Perry et al.: Nursing Interventions & Clinical Skills, 6th Edition

MULTIPLE CHOICE

1. The patient’s oral temperature is 39° C. Which conclusion can the nurse make about the patient on the basis of this information?

a.

The patient is febrile.

b.

The patient is afebrile.

c.

An infection is present.

d.

Inflammation is present.

ANS: A

A temperature of 39° C is above normal, and the patient with an above-average temperature is febrile. Afebrile indicates a lack of fever but does not necessarily imply a subnormal temperature. An infection often causes a fever in the patient, but a physical examination and laboratory work or culture are necessary before concluding that the patient has an infection. A patient with an inflammation can have a fever, but the patient can have an inflammation without being febrile.

2. The nurse is preparing to obtain a set of vital signs. Which is the most important factor for the nurse to consider when measuring patient vital signs?

a.

Documentation of vital signs requires timely and accurate recording.

b.

Normal limits are very narrow and are generally the same for all patients.

c.

Measuring equipment must be used correctly and appropriately.

d.

Environmental factors play a minor role on patient vital signs.

ANS: C

It is important that each device be used correctly and appropriately to ensure patient safety and to obtain correct, complete patient information. Improper equipment distorts the results, increasing the risk of patient injury. If data are obtained with improper equipment and patient treatment is based on the faulty data, the people who use the improper equipment and the faulty data are liable for the results. This is especially important when assessing temperature and blood pressure since a variety of devices are available for measuring these vital signs. Documentation is an important part of taking vital signs; however, if the nurse uses improper equipment or technique to obtain vital signs, accurate and prompt recording is to no avail. Depending on the parameter, the normal limits are not relatively narrow. The benefit of a wider normal range is that the body is able to respond to stress and recover while remaining within normal limits. Environmental factors play a significant role on vital signs (e.g., an overly warm room affects patient temperature).

3. A patient has a severe upper respiratory and ear infection and has been experiencing diarrhea. Assessment of the temperature would be most accurate if the nurse checked the temperature using which site?

a.

The rectum

b.

The axilla

c.

Under the tongue

d.

The tympanic membrane

ANS: B

The axilla is the only area listed where there is no infection or health issue and where there is no interference to its accuracy. The rectum is an inappropriate site because of the diarrhea. The oral route, under the tongue, is an inappropriate site because of the severe upper respiratory infection. If the patient cannot breathe through the nose, mouth breathing occurs, and the mouth cannot be closed to create a seal for an accurate temperature measurement. The tympanic membrane is an inappropriate site because of the ear infection.

4. The nurse is validating the measurement of an infant’s pulse by a nursing student. Which method should the nurse use to obtain the most accurate count?

a.

Compress the bell of the stethoscope over the apex of the heart.

b.

Locate the pulsations in the antecubital space.

c.

Palpate the superficial artery on the medial side of the wrist.

d.

Place the thumb and forefinger along the ridge on the outer side of the wrist.

ANS: B

Counting the pulsations in the antecubital fossa from the brachial artery would give the most accurate count. Compressing the bell of the stethoscope turns it into a diaphragm; the bell is never compressed during use. Placing the thumb and forefinger along the ridge on the outer side of the wrist locates the radial artery, the preferred site for measuring an adult’s pulse.

5. A patient born without arms needs to have a blood pressure assessment. Which artery should the nurse use to most accurately obtain this measurement?

a.

Femoral

b.

Carotid

c.

Brachial

d.

Popliteal

ANS: D

The nurse can use the popliteal artery to measure blood pressure by applying a properly sized cuff to the patient’s thigh. The femoral artery does not provide an area for assessment of the blood pressure. The brachial arteries are in the arm. The carotid artery, which is in the neck, is impossible to use for blood pressure measurement because applying cuff pressure to temporarily occlude both carotid arteries would stop blood flow to the brain and risk cerebral hypoxia.

6. The nurse is running a blood pressure screening clinic at the community health center. Which action should the nurse implement to obtain an accurate measurement of a patient’s blood pressure on an upper extremity?

a.

Use a cuff with a cuff width that is 40% wider than the circumference of the arm.

b.

Limit the cuff deflation rate to 10 mm Hg per second or heartbeat.

c.

Record the second Korotkoff sound as the systolic pressure.

d.

Apply the diaphragm of the stethoscope lightly over the brachial artery.

ANS: A

For accurate results, a properly sized blood pressure cuff is at least 40% wider than the circumference of the patient’s arm on which the blood pressure is measured. Deflating the cuff at 10 mm Hg is excessively fast. The systolic blood pressure is the first Korotkoff sound. The diaphragm is placed firmly over the brachial artery to prevent environmental sound from interfering with blood pressure auscultation.

OBJ: NCLEX: Physiological Integrity TOP: Nursing Process: Implementation

7. The patient is unstable; so the nurse is using an electronic blood pressure device to measure blood pressures every 15 minutes. What should the nurse do to verify the accuracy of the electronic blood pressure measurements?

a.

Check when the device was last calibrated.

b.

Know that the device adheres to current medical industry standards.

c.

Take a manual blood pressure within several minutes of the electronic reading.

d.

Verify that the systolic pressure is within 20% of patient baseline.

ANS: C

If the blood pressure readings from the electronic blood pressure measurement device are close to the patient’s blood pressure on auscultation using a sphygmomanometer, the nurse assumes that the electronic device is accurate. Knowing when the device was calibrated does not guarantee its current accuracy. Medical industry standards do not exist for electronic blood pressure devices. A systolic measurement accurate within 20% of the patient’s baseline is grossly inaccurate, and using such a measurement can potentially lead to catastrophic results.

8. A patient has an electronic blood pressure cuff that inflates every 15 minutes for a reading. Which activity by the nursing student would require the nurse to intervene?

a.

The cuff is positioned carefully on the gown sleeve for comfort.

b.

The cuff is removed every 2 hours for a skin assessment.

c.

The alarm limits on the electronic device are checked frequently.

d.

The cuff is rotated to the other extremity every few hours as possible.

ANS: A

The cuff should be directly on the patient’s skin, not over the gown, for an accurate reading. All other actions are appropriate.

9. The nurse delegates temperature measurement to nursing assistive personnel (NAP). For which patient should the nurse instruct the NAP to use the tympanic thermometer?

a.

10-year-old patient with a left leg fracture

b.

12-hour-old infant in the newborn nursery

c.

5-year-old patient with bilateral otitis media

d.

15-year-old patient with postbilateral tympanoplasties

ANS: A

The 10-year-old patinet is a suitable candidat for use of the typmanic thermometer if the NAP uses proper technique for positioning the sensor becaue of the age and condition of the child. The anatomy of the ear canal makes it difficult to position the probe accurately in neonates. Whenever ear infections are present, a tympanic thermometer can cause injury and record an inaccurate reading because of fluid, wax, or infectious material in the ear. Tympanic temperatures are prohibited when ear surgery has just been performed because they increase the risk for injury and infection.

10. The nurse needs to measure the adult patient’s temperature, but the patient has just finished a cup of coffee. Which is the best type of temperature for the nurse to obtain accurate results efficiently?

a.

Rectal

b.

Axillary

c.

Tympanic

d.

Disposable

ANS: C

The nurse obtains a tympanic temperature because the hot coffee will affect an oral reading. A tympanic temperature is a more reliable indicator of body temperature than the oral reading because a tympanic temperature is a core temperature. Rectal temperatures for adult patients are reserved for occasions when continuous temperature monitoring is required or if no other core temperature site is available; in addition, rectal temperatures are embarrassing for an alert adult patient. Axillary temperatures are not as reliable as tympanic temperatures and do not reflect core temperature. Disposable thermometers are the least accurate method.

11. The nurse is preparing to obtain a rectal temperature. Nursing care is correct if the nurse inserts the thermometer how far into the rectum of an adult?

a.

1.3 cm (1/2 inch)

b.

3.5 cm (1 1/2 inches)

c.

5.1 cm (2 inches)

d.

6.4 cm (1 1/2 inches)

ANS: B

The nurse inserts the thermometer 2.5 to 3.5 cm (1 to 1 1/2 inches) to obtain a rectal temperature on an adult. The sensor tip will be deep enough into the rectum to eliminate environmental effects but not too deep to risk penetration or trauma to intestinal tissue. 1.3 cm (1/2 inch) is not far enough for an accurate reading. 5.1 and 6.4 cm (2 and 2 1/2 inches) are too far to insert the thermometer into an adult.

DIF: Cognitive Level: Comprehend REF: Page 109

OBJ: NCLEX: Physiological Integrity TOP: Nursing Process: Implementation

12. While inserting a rectal thermometer, the nurse encounters resistance. What action should the nurse take?

a.

Remove the thermometer immediately.

b.

Ask the patient to take a few deep breaths.

c.

Apply mild pressure to advance the thermometer.

d.

Remove the thermometer and reinsert gently.

ANS: A

If resistance is felt, the nurse should remove the thermometer probe. Applying pressure to advance the thermometer is contraindicated to prevent complications such as harm to the mucosa. If there is an obstruction or a large amount of stool, having the patient take a few deep breaths is useless. The obstruction or impaction will have to be dealt with first. If the nurse removes and then reinserts the thermometer, the stimulation reactivates the sphincter reflex. The resistance will more than likely still be present.

13. The nurse notes that the patient’s tympanic temperature is 37.88° C (100.2° F) at 4 PM on the patient’s second postoperative day. What should the nurse do initially?

a.

Check the leukocyte count.

b.

Collaborate for cultures.

c.

Ask the patient to drink some fluid.

d.

Offer the patient another blanket.

ANS: C

The nurse should ask the patient to drink more fluid and cough and deep breathe because low-grade temperatures frequently indicate dehydration and atelectasis in postoperative patients; in addition, patient temperatures generally peak in late afternoon. The nurse evaluates the patient’s temperature again in 2 hours and expects to obtain a lower temperature. If not, the nurse assesses the patient for infection and collaborates with the provider to plan care. Until the nurse tries fluid and verifies the temperature, collaborating for specimen cultures is premature; in addition, the provider potentially will not want to culture for a low-grade temperature.

14. The nurse is teaching a family member how to check a teenager’s temperature using a tympanic thermometer. Which step is most important for the nurse to include in order to obtain an accurate reading?

a.

Pull the pinna down and back.

b.

Pull the pinna up and back.

c.

Place the probe loosely into the ear canal.

d.

Point the probe toward the eye.

ANS: B

To obtain a tympanic temperature using proper technique, the nurse inserts the thermometer tip into the ear, and pulls the pinna up and back for children older than 3. The tip must fit securely in the ear canal to block environmental effects. The tip of the thermometer should point toward the patient’s nose for proper positioning.

15. A patient has been experiencing some circulatory issues, and an apical-radial pulse is ordered. Nursing care is correct if which procedure is followed?

a.

One nurse counts the apical pulse at the same time another nurse counts the radial pulse.

b.

The nurse delegates this procedure to an experienced licensed practical nurse/licensed vocational nurse (LPN/LVN) and nursing assistive personnel (NAP) with 10 years’ experience.

c.

The nurse counts the apical pulse for 60 seconds and then the radial pulse for 60 seconds.

d.

The apical pulse is counted for 30 seconds, the radial pulse for 30 seconds, and the results are doubled.

ANS: A

The pulse rate must be counted for 60 seconds at the two sites at the same time by two different people. If the patient is unstable or experiencing problems, this cannot be delegated to NAP. The radial and apical pulses are counted at the same time by two different people. The apical and radial pulses are counted for a full minute, not 30 seconds.

16. The nurse is preparing to measure the patient’s blood pressure with an electronic blood pressure device. Which concept is most important for the nurse to consider?

a.

Use the extremity closest to the nurse.

b.

The cuff size must match the extremity being used.

c.

The brachial artery is always the best one to use.

d.

The temporal artery is used if neither arm is available.

ANS: B

The cuff must be the appropriate size for the extremity used. If the thigh is used, the nurse must use a larger cuff. The extremity used has nothing to do with proximity to the nurse. It depends on the patient’s status. In some instances the brachial artery in the upper arm is not available for blood pressure assessment such as after a mastectomy, if the extremity is injured, or if an intravenous line is in place. The temporal artery is impossible to use for blood pressure measurement because the temporal arteries are on the lateral aspects of the skull.

17. The nurse is preparing to assess the apical pulse. At which location should the nurse listen to obtain an accurate apical pulse on an adult patient?

a.

At the fifth intercostal space at the left sternal border

b.

At the fifth left intercostal space at the midclavicular line

c.

At the second intercostal space at the left midclavicular line

d.

At the second right intercostal space at the midclavicular line

ANS: B

To auscultate an adult’s apical pulse, the nurse places the stethoscope at the left fifth intercostal space at the midclavicular line directly over the point of maximal impulse and the location for auscultating the mitral valve. The fifth left intercostal space at the left sternal border locates the tricuspid valve. The second intercostal space at the left midclavicular line locates the pulmonic valve. The second right intercostal space at the midclavicular line locates the aortic valve.

18. The nursing assistant reports the following vital signs for four patients just evaluated. Which patient should the nurse see first?

a.

25 respirations per minute for a toddler

b.

38 respirations per minute for a newborn

c.

12 respirations per minute for an 8-year-old child

d.

14 respirations per minute for an adult patient

ANS: C

The 8-year-old child is the nurse’s priority because the rate is too slow for the patient’s developmental stage. The normal range for a child is 20 to 30 breaths per minute. The range for respirations for a toddler is 25 to 32 breaths per minute; thus 25 breaths are within the normal limits. The range for respirations for a newborn is 35 to 40 breaths per minute; thus 38 breaths are within the normal limits. The range for respirations for an adult is 12 to 20 breaths per minute; thus 14 breaths are within the normal limits.

19. At what distance above the antecubital fossa does the nurse position a blood pressure (BP) cuff when using the brachial artery to measure BP?

a.

2.5 cm (1 inch)

b.

0.6 cm (1/4 inch)

c.

1.3 cm (1/2 inch)

d.

5.1 cm (2 inches)

ANS: A

The nurse positions the BP cuff 2.5 cm (1 inch) above the antecubital fossa when using the brachial artery. This allows proper placement of the stethoscope.

20. The patient is morbidly obese and the nurse uses a blood pressure (BP) cuff that is too narrow for the patient’s arm. What problem will the nurse encounter because of the cuff used?

a.

The Korotkoff sounds will not be heard.

b.

Only a palpable BP can be obtained.

c.

The stethoscope cannot be positioned correctly.

d.

A false high BP reading will occur.

ANS: D

Using a cuff that is too narrow results in a false high BP measurement and makes care planning impossible. A properly sized cuff should be obtained as quickly as possible. Until it arrives, the nurse should continue to measure BP with the smaller cuff and observe the patient to ensure safety. Obesity potentially leads to diminished Korotkoff sounds. The assessment finding will warrant further investigation such as rechecking the blood pressure in several minutes. A palpable BP provides a systolic pressure only; the nurse obtains a palpable BP by inflating the cuff to occlude the artery and then palpating the brachial or radial pulse. The point at which the pulse returns is the systolic pressure. The nurse should have less difficulty positioning the stethoscope because the narrow cuff exposes more skin.

21. The nurse is assessing a new orientee’s knowledge of when to take vital signs. The following statement indicates a need for more education.

a.

I should take vital signs upon admission.

b.

I should take vital signs when there is any change in condition.

c.

I should take vital signs at the beginning and end of a blood transfusion.

d.

I should take vital signs if a patient reports feeling different.

ANS: C

Vital signs should be taken in all of those situations including before and after blood transfusions, but they also need to be taken during blood transfusions. The nurse would want to clarify that statement to make sure the nurse knows to check the vital signs during blood transfusions.

22. While positioning the patient for a routine blood pressure check, the patient asks the nurse why a support was placed under the arm before the BP cuff was applied. Which response by the nurse is most accurate?

a.

“This method prevents any problems in obtaining an accurate reading.”

b.

“This method helps the arm relax so the reading will be correct.”

c.

“I want you to be as comfortable as possible during this time.”

d.

“Just sit back and relax and let me get this reading right now.”

ANS: B

Supporting the arm ensures the muscles are relaxed, improving the likelihood for an accurate reading. Comfort is important but not the primary reason for providing support. Many variables can cause an inaccurate reading, including the wrong cuff size or improper placement of the stethoscope. Telling the patient to just “sit back and relax” ignores the patient’s question and is not an appropriate response.

23. The nurse assesses the patient’s respirations and sees that they are abnormally shallow (i.e., two to three breaths followed by an irregular period of apnea). Documentation by the nurse would be correct if which phrase were used?

a.

Biot’s respirations

b.

Cheyne-Stokes respirations

c.

Kussmaul’s respirations

d.

Hyperpneic respirations

ANS: A

This is an accurate description of Biot’s respirations. Cheyne-Stokes respirations have an irregular rate and depth characterized by alternating periods of apnea and hyperventilation. Kussmaul’s respirations are abnormally deep but regular. Hyperpneic respirations are increased in depth and can often be seen during exercise.

24. The nurse is caring for a lethargic, 18-year-old patient with a respiratory rate of 32 breaths per minute. What is the first action the nurse should take?

a.

Place the patient in high-Fowler’s position.

b.

Assess the remaining vital signs.

c.

Reassess the respiratory rate.

d.

Notify the healthcare provider.

ANS: A

The patient’s head should be elevated quickly to promote better lung expansion. The remaining vital signs can be assessed after taking actions to improve the patient’s breathing. The healthcare provider will be notified, but the nurse’s first responsibility is to the patient.

25. You have delegated the task of obtaining a pulse oximetry reading to the NAP. Which of the following statements by the NAP indicates a need for further education?

a.

“The pulse oximetry reading was 95%.”

b.

“The patient’s pulse rate was 78 according to the readout.”

c.

“I made sure the patient did not have nail polish on.”

d.

“I made sure the patient was not receiving a respiratory treatment.”

ANS: B

Pulse oximetry should not be used to obtain heart rates because they will not detect an irregular pulse. The patient’s nail polish should be removed and the patient should not be receiving respiratory treatments or PT during the readings because it can affect them. The readings are given in percentages.

26. The patient’s oral temperature is 37.1° C (98.78° F) at 1 PM. Which of the following actions should the nurse take next? (Select all that apply.)

a.

Administer acetaminophen (Tylenol) 650 mg by mouth now.

b.

Off the patient an additional blanket.

c.

Document that the patient is normotensive.

d.

Compare this with the patient’s prior readings.

ANS: C

This temperature is within normal limits. Because the temperature reading is within normal limits, other intervnetions are not needed. Providing a blanket would increase the temperature. Comparing the temperature with other readings would be done if the temperature was outside of the normal range. Treating the patient with acetaminophen would be done if the patient’s temperature was elevated and you had a healthcare provider order.
