,Q1. A patient presents with a core temperature of 39.5°C (103.1°F) measured rectally.
Which physiological response is most likely to be impaired, and what compensatory
mechanism might be blunted?
A. Vasodilation of cutaneous vessels; shivering thermogenesis
B. Sweating; nonshivering thermogenesis in brown adipose tissue
C. Vasoconstriction of peripheral vessels; piloerection
D. Increased metabolic rate; behavioral thermoregulation
Correct Answer: B. Sweating; nonshivering thermogenesis in brown adipose tissue
Rationale: At a core temperature of 39.5°C, the hypothalamus is set to a higher set point;
the body attempts to lose heat via sweating and vasodilation. Shivering and nonshivering
thermogenesis are heat-producing mechanisms that are suppressed during fever.
Vasoconstriction and piloerection conserve heat and are inappropriate during fever.
Behavioral thermoregulation is a conscious response, not a primary physiological
compensation.
Why Wrong:
A - Vasodilation is correct, but shivering thermogenesis is a heat-producing response
that would be inhibited, not impaired.
C - Vasoconstriction and piloerection are heat-conserving responses, opposite to what
is expected during fever.
D - Increased metabolic rate and behavioral thermoregulation are not the primary
physiological compensatory mechanisms during fever.

Q2. A patient's radial pulse is irregular. Upon auscultation of the apical pulse, the
nurse notes a rate of 88 beats/min, while the radial pulse is 72 beats/min. Which
condition best explains this discrepancy, and what is the resulting pulse deficit?
A. Atrial fibrillation; pulse deficit of 16 beats/min
B. Premature ventricular contractions; pulse deficit of 16 beats/min
C. Sinus arrhythmia; pulse deficit of 16 beats/min
D. Third-degree heart block; pulse deficit of 16 beats/min
Correct Answer: A. Atrial fibrillation; pulse deficit of 16 beats/min
Rationale: A pulse deficit (apical minus radial) occurs when some cardiac contractions do
not generate a palpable peripheral pulse, as seen in atrial fibrillation due to weak or
non-perfusing beats. The difference is 88 - 72 = 16 beats/min. Premature ventricular
contractions can also cause a pulse deficit, but atrial fibrillation is the classic cause of a
persistent, irregularly irregular pulse with a deficit. Sinus arrhythmia is a normal
variation with no deficit. Third-degree heart block causes bradycardia, not an irregular
pulse with a deficit.
Page 3
, Why Wrong:
B - PVCs can cause a pulse deficit, but the classic cause of an irregularly irregular
pulse with a significant deficit is atrial fibrillation.
C - Sinus arrhythmia is a normal variation and does not produce a pulse deficit.
D - Third-degree heart block typically presents with bradycardia and may have a pulse
deficit, but the rhythm is regular, not irregular.

Q3. A nurse is measuring a patient's blood pressure using a cuff that is too narrow for
the arm circumference. Which of the following errors will most likely occur, and what
is the underlying physiological mechanism?
A. Falsely low reading; incomplete occlusion of the brachial artery
B. Falsely high reading; excessive pressure needed to compress the artery
C. Falsely low reading; auscultatory gap due to turbulent flow
D. Falsely high reading; inability to detect Korotkoff sounds
Correct Answer: B. Falsely high reading; excessive pressure needed to compress the
artery
Rationale: A cuff that is too narrow requires higher inflation pressure to compress the
brachial artery, leading to a falsely elevated blood pressure reading. This is because the
pressure is not distributed evenly, and more force is needed to occlude the artery. A cuff
that is too wide yields falsely low readings. Auscultatory gap is related to cuff deflation,
not cuff size. Inability to detect Korotkoff sounds is not a direct consequence of cuff width.
Why Wrong:
A - Incomplete occlusion would cause a falsely low reading, but a narrow cuff
over-occludes, not under-occludes.
C - Auscultatory gap is a phenomenon of auscultation, not cuff size, and it causes a
falsely low systolic reading.
D - Inability to detect Korotkoff sounds would cause a falsely low reading, not high,
and is not due to cuff width.

Measurement in Humans
Q4. A patient with chronic obstructive pulmonary disease (COPD) has an SpO2 of
88% on room air. The nurse notes that the patient is alert and oriented. Which
nursing action is most appropriate, and what is the rationale?
A. Administer high-flow oxygen to raise SpO2 to 100%; prevents tissue hypoxia
B. Maintain current oxygen therapy; target SpO2 of 88-92% to avoid suppressing
hypoxic drive
C. Increase oxygen to achieve SpO2 of 94%; ensures adequate cerebral oxygenation
D. Discontinue oxygen therapy; SpO2 of 88% is acceptable in COPD
