1 of 5
A nurse is assessing a client who is nonverbal for acute pain. Which of the following findings is a manifestation of pain?
Correct Answer: B
Rationale: Elevated blood pressure is a common response to acute pain due to sympathetic nervous system activation. Pain typically increases respiratory and heart rates and dilates pupils, not the opposite.
Question 2 of 5
A nurse is caring for a client who is receiving oxygen at $2 \mathrm{~L}/\min$ via a nasal cannula. The nurse recognizes the client is receiving which of the following inspired oxygen concentration?
Correct Answer: D
Rationale: At 2 L/min via nasal cannula, the inspired oxygen concentration is approximately 24-28%, as each liter adds about 4% to the room air’s 21%. Thus, 28% is correct.
Question 3 of 5
A nurse is caring for a client who has chronic obstructive pulmonary disease (COPD). The client tells the nurse, 'I can feel the congestion in my lungs, and I certainly cough a lot, but I can’t seem to bring anything up.' Which of the following actions should the nurse take to help this client with tenacious bronchial secretions?
Correct Answer: C
Rationale: Increased fluid intake thins bronchial secretions, aiding expectoration in COPD. Low-salt diets, oxygen, and semi-Fowler’s position don’t directly address secretion viscosity.
Question 4 of 5
Which activity should the nurse implement to decrease shearing force on a client's stage II pressure injury?
Correct Answer: D
Rationale: Preventing sliding in bed reduces shearing forces that worsen pressure injuries. Pulling up under arms increases shear, hydration aids skin health indirectly, and cream reduces friction, not shear.
Question 5 of 5
A nurse is teaching a client about the sleep-wake cycle. The nurse should include that which of the following factors can interfere with the sleep-wake cycle? (Select All that Apply)
Correct Answer: A,B,C,D
Rationale: Bright light disrupts melatonin production, delaying sleep. Evening caffeine blocks adenosine, reducing sleepiness. A 20-minute nap, especially late in the day, can reduce nighttime sleep drive. Emotional stress increases alertness, hindering sleep. A regular bedtime schedule reinforces the sleep-wake cycle, not disrupts it.
