1. Which of the following examination techniques would MOST efficiently screen for the expected
dysfunction in a patient whose skin distal to the mid-calf is darker than the skin proximal to the mid-
calf?
A) Capillary refill time
B) Venous filling time
C) Dorsalis pedis pulse
D) Sensory filament testing
Correct Answer: Venous filling time
Rationale: Darkened skin distal to the mid-calf is characteristic of chronic venous insufficiency, where
venous stasis leads to hemosiderin deposition. Venous filling time directly assesses venous return and
valvular function. Capillary refill and pulse assessments evaluate arterial status, while sensory testing
addresses neurologic function.
2. Which of the following ranges for respiratory rate would be NORMAL for an 8-year-old child?
A) 12 to 20 breaths per minute
B) 18 to 30 breaths per minute
C) 24 to 40 breaths per minute
D) 30 to 60 breaths per minute
Correct Answer: 18 to 30 breaths per minute
Rationale: Normal respiratory rate for a school-aged child (6–12 years) is 18–30 breaths per minute. The
12–20 range applies to adults, 24–40 applies to toddlers (1–3 years), and 30–60 applies to infants (0–12
months). Knowing age-appropriate vital signs is essential for accurate patient assessment.
3. Which clinical manifestation would MOST likely be associated with right ventricular failure?
,A) Pulmonary edema
B) Jugular venous distention
C) Paroxysmal nocturnal dyspnea
D) Muscular weakness and fatigue
Correct Answer: Jugular venous distention
Rationale: Right ventricular failure causes backup of blood into the systemic venous system, resulting in
jugular venous distention, peripheral edema, and hepatomegaly. Pulmonary edema, paroxysmal
nocturnal dyspnea, and orthopnea are hallmark signs of left ventricular failure, not right-sided failure.
4. Which heart sound heard in a 70-year-old adult MOST likely indicates ventricular failure?
A) S1
B) S2
C) S3
D) S4
Correct Answer: S3
Rationale: An S3 heart sound (ventricular gallop) in an older adult is abnormal and suggests decreased
ventricular compliance or heart failure. S1 and S2 are normal heart sounds. S4 may indicate restrictive
cardiomyopathy or aortic stenosis but is not specifically associated with ventricular failure.
5. Which scenario BEST describes the effect of climatic conditions on an individual who has exercise-
induced asthma?
A) Bronchospasm is facilitated by exercise in a humid environment compared with a dry environment
B) Bronchospasm is facilitated by exercise in a warm environment compared with a cold environment
C) Bronchospasm is blunted when exercising in a cold, dry environment compared with a warm, humid
environment
D) Bronchospasm is facilitated by exercise in a cold, dry environment compared with a warm, humid
environment
, Correct Answer: Bronchospasm is facilitated by exercise in a cold, dry environment compared with a
warm, humid environment
Rationale: Cold, dry air causes increased heat and water loss from the airways, triggering bronchospasm
in exercise-induced asthma. Warm, humid environments reduce airway irritation and are protective. The
other options reverse or misstate this established physiologic relationship.
6. Which of the following interventions is MOST appropriate for a patient with chronic obstructive
pulmonary disease who demonstrates prolonged expiratory phase and pursed-lip breathing?
A) Incentive spirometry
B) Pursed-lip breathing
C) Segmental breathing
D) Glossopharyngeal breathing
Correct Answer: Pursed-lip breathing
Rationale: Pursed-lip breathing creates positive end-expiratory pressure, which keeps small airways
open during expiration and reduces air trapping in COPD. Incentive spirometry promotes deep
inspiration. Segmental breathing targets specific lung regions. Glossopharyngeal breathing is used in
neuromuscular conditions with ventilatory impairment.
7. A patient with Fair (3/5) quadriceps strength, intact sensation, and 0/10 pain would benefit MOST
from which electrical stimulation parameters?
A) Frequency of 35 pps, duration of 50 microseconds
B) Frequency of 35 pps, duration of 150 microseconds
C) Frequency of 50 pps, duration of 250 microseconds
D) Frequency of 150 pps, duration of 50 microseconds
Correct Answer: Frequency of 50 pps, duration of 250 microseconds
