1. A healthcare professional is asked to draw blood in the antecubital (AC) space. Which of the following veins are found in the AC?

• A. Cephalic
• B. Median cubital
• C. Basilic
• D. All of the above

Correct answer: D

Rationale: The correct answer is 'All of the above.' All three of these veins - the cephalic, median cubital, and basilic veins - are located in the antecubital space, which is the area in front of the elbow on the arm. The cephalic vein runs along the outer side of the arm, the basilic vein runs along the inner side of the arm, and the median cubital vein is a connecting vein between the cephalic and basilic veins. Therefore, all three veins can be accessed when drawing blood from the antecubital space. Choices A, B, and C are incorrect because each of these veins individually can be found in the antecubital space.

2. How does the procedure for taking a pulse rate on an infant differ from an adult?

• A. Pulse rates are taken on infants using a different method.
• B. The apical pulse method is used on infants.
• C. Pulse rates on infants are taken with a sphygmomanometer.
• D. Pulse rates on infants are taken apically in the third intercostal space.

Correct answer: B

Rationale: The correct answer is B: The apical pulse method is used on infants. This method involves placing a stethoscope in the fifth intercostal space, mid-clavicular line, and counting the beats for a full minute. It is a preferred method for infants due to their small size and the difficulty in palpating peripheral pulses accurately. Choices A, C, and D are incorrect. Choice A is incorrect as pulse rates are indeed taken on infants, albeit using a different method. Choice C is incorrect as a sphygmomanometer is typically used for measuring blood pressure, not pulse rates. Choice D is incorrect as pulse rates on infants are usually taken apically in the fifth intercostal space, not the third.

3. The nurse is conducting a health fair for older adults. Which statement is true regarding vital sign measurements in aging adults?

• A. The pulse is easier to palpate due to the rigidity of the blood vessels.
• B. An increased respiratory rate and a shallower inspiratory phase are expected findings.
• C. A widened pulse pressure occurs from changes in the systolic and diastolic blood pressures.
• D. Changes in the body's temperature regulatory mechanism decrease the older adult's likelihood of developing a fever.

Correct answer: B

Rationale: Aging causes a decrease in vital capacity and decreased inspiratory reserve volume. As a result, the examiner may observe a shallower inspiratory phase and an increased respiratory rate in older adults. Contrary to common belief, the increased rigidity of arterial walls actually makes the pulse easier to palpate in aging adults. Pulse pressure is widened, not decreased, due to changes in systolic and diastolic blood pressures. Furthermore, changes in the body's temperature regulatory mechanism make older individuals less likely to develop a fever but more susceptible to hypothermia.

4. A 4-month-old child is at the clinic for a well-baby checkup and immunizations. Which of these actions is most appropriate when the nurse is assessing an infant's vital signs?

• A. The infant's radial pulse should be palpated, and the nurse should notice any fluctuations resulting from activity or exercise.
• B. The nurse should auscultate an apical rate for 1 minute and then assess for any normal irregularities, such as sinus dysrhythmia.
• C. The infant's blood pressure should be assessed by using a stethoscope with a large diaphragm piece to hear the soft muffled Korotkoff sounds.
• D. The infant's chest should be observed and the respiratory rate counted for 1 minute; the respiratory pattern may vary significantly.

Correct answer: B

Rationale: The nurse auscultates an apical rate, not a radial pulse, with infants and toddlers. The pulse should be counted by listening to the heart for 1 full minute to account for normal irregularities, such as sinus dysrhythmia. Children younger than 3 years of age have such small arm vessels; consequently, hearing Korotkoff sounds with a stethoscope is difficult. The nurse should use either an electronic blood pressure device that uses oscillometry or a Doppler ultrasound device to amplify the sounds. An infant's respiratory rate should be assessed by observing the infant's abdomen, not chest, because an infant's respirations are normally more diaphragmatic than thoracic. The nurse should auscultate an apical heart rate, not palpate a radial pulse, with infants and toddlers.

5. When measuring the vital signs of a 6-month-old infant, which action by the nurse is correct?

• A. Respirations are measured first, followed by pulse and temperature.
• B. Vital signs should be measured as frequently as in an adult.
• C. Procedures are explained to the parent, and the infant is encouraged to handle the equipment.
• D. The nurse should first measure the infant's vital signs before performing a physical examination.

Correct answer: A

Rationale: When assessing vital signs in a 6-month-old infant, the correct order is to measure respirations first, followed by pulse and temperature. This sequence is important to avoid potential alterations in respiratory and pulse rates caused by factors like crying or discomfort. Measuring the temperature first, especially rectally, may lead to an increase in respiratory and pulse rates, which can skew the results. It is crucial to follow this specific order to obtain accurate baseline values. Therefore, option A is the correct choice. Option B is incorrect as the frequency of measuring vital signs in infants differs based on individual needs rather than being consistently more frequent than in adults. Option C is not directly related to the correct sequence for measuring vital signs in infants. Option D is incorrect because the physical examination typically follows the assessment of vital signs in clinical practice.
