B. 150 minutes
C. 300 minutes
D. 60 minutes
Answer: B
Rationale: The current guidelines recommend that adults engage in at least 150 minutes of
moderate-intensity aerobic activity per week for substantial health benefits.
2. Which of the following describes ‘Isotonic’ exercise?
A. Muscle contraction with change in muscle length and joint movement
B. Muscle contraction without shortening the joint
C. Resistance against a fixed object
D. High-intensity bursts of activity without oxygen
Answer: A
Rationale: Isotonic exercises involve muscle shortening and active movement, such as
walking, swimming, or bicycling.
,3. A patient has a Body Mass Index (BMI) of 28.5 kg/m2. How should the nurse
classify this patient’s weight status?
A. Underweight
B. Normal weight
C. Overweight

4. Which stage of the sleep cycle is characterized by vivid, full-color dreaming
and increased heart rate?
A. NREM Stage 1
B. REM Sleep
C. NREM Stage 3
D. NREM Stage 2

7. Which nutrient is essential for wound healing and collagen synthesis?
A. Vitamin D
B. Vitamin B12

A. Exercise vigorously right before bedtime
B. Use the bedroom only for sleep and sex
C. Drink a glass of red wine to help fall asleep
