Q1Which of the following blood pressure readings would be classified as Stage 1 hypertension in an adult patient?
Show answer
✓ Correct answer: 138/88 mmHg
Stage 1 hypertension is defined as systolic blood pressure of 130-139 mmHg or diastolic blood pressure of 80-89 mmHg. The reading of 138/88 mmHg falls within this range.
Q2A respiratory rate of 36 breaths per minute would be considered normal in which of the following patients?
Show answer
✓ Correct answer: Newborn infant
In newborn infants, a respiratory rate of 30-60 breaths per minute is considered normal. For adults, normal respiratory rates range from 12-20 breaths per minute, while school-age children typically have rates of 18-30 breaths per minute. A rate of 36 would be abnormally high for an adult but within normal range for a newborn.
Q3When measuring blood pressure, which of the following techniques is considered correct?
Show answer
✓ Correct answer: Placing the cuff on bare skin, not over clothing
For proper blood pressure measurement, the patient should be seated with back supported and feet flat on the floor, arm supported at heart level, and should avoid talking during measurement. The cuff should be placed on bare skin, not over clothing.
Q4Which pulse characteristic is associated with aortic regurgitation?
Show answer
✓ Correct answer: Water-hammer (collapsing) pulse
A water-hammer or collapsing pulse (Corrigan's pulse) is characterized by a rapid upstroke and collapse, which is typically found in patients with aortic regurgitation. It represents the rapid ejection of blood followed by rapid runoff due to backward flow across the incompetent aortic valve.
Q5A patient presents with a temperature of 95.1°F (35.1°C). This finding is consistent with:
Show answer
✓ Correct answer: Mild hypothermia
Hypothermia is defined as a core body temperature below 95°F (35°C). A temperature of 95.1°F (35.1°C) indicates mild hypothermia, which can occur due to environmental exposure, metabolic disorders, or certain medications.
Q6Which of the following pulse rates would be considered tachycardia in an adult patient at rest?
Show answer
✓ Correct answer: 112 beats per minute
Tachycardia in adults is defined as a heart rate greater than 100 beats per minute. A resting pulse of 112 bpm would be classified as tachycardia and warrants further investigation.
Q7Pulsus paradoxus, an abnormal decrease in systolic blood pressure during inspiration, is most commonly associated with which condition?
Show answer
✓ Correct answer: Cardiac tamponade
Pulsus paradoxus is an exaggerated drop in systolic blood pressure during inspiration (greater than 10 mmHg). It is classically associated with cardiac tamponade, but can also be found in severe asthma, COPD, and pericarditis.
Q8Which vital sign change would most likely be observed in a patient with significant blood loss?
Show answer
✓ Correct answer: Increased heart rate
With significant blood loss, compensatory mechanisms attempt to maintain perfusion to vital organs. This typically results in tachycardia (increased heart rate) as the body tries to maintain cardiac output despite reduced blood volume.
Q9The proper technique for measuring respiratory rate includes:
Show answer
✓ Correct answer: Counting breaths for 60 seconds without the patient's awareness
To accurately measure respiratory rate, the practitioner should count the number of breaths over a full 60 seconds without the patient's awareness. Patients who are aware their breathing is being monitored may consciously or unconsciously alter their breathing pattern, resulting in an inaccurate measurement.
Q10During examination of the eyes, which of the following pupillary responses would be considered abnormal?
Show answer
✓ Correct answer: Unequal pupil size in response to the same light stimulus
Unequal pupil size (anisocoria) under the same lighting conditions is an abnormal finding that may indicate neurological issues, trauma, or other pathologies affecting the pupils or their neural pathways.
