# SECTION I: FUNDAMENTAL CONCEPTS OF COMFORT, REST,
AND SLEEP (Questions 1-10)
**1. A nurse is teaching a client about the difference between rest and
sleep. Which statement by the client indicates correct understanding?**
A) "Rest and sleep are the same and cannot be distinguished."
B) "Rest is a state of mental and physical relaxation without necessarily
being asleep."
C) "Sleep requires complete unconsciousness, while rest requires only
lying down."
D) "Rest is only physical, while sleep is only mental."
**Correct Answer: B**
**Rationale:** Rest is a state of calm, relaxation, and reduced activity
(mental and physical) that does not require unconsciousness. Sleep is a
state of altered consciousness with reduced responsiveness to external
stimuli. Option A is incorrect; they are distinct. Option C is incorrect
because sleep is not complete unconsciousness (it is reversible). Option
D is incorrect because both have mental and physical components.

**2. A nurse is planning care for a hospitalized client. Which statement
best describes the purpose of promoting adequate sleep?**
A) Sleep allows the body to conserve energy for the next day only.
B) Sleep is a passive state with no physiological benefits.
C) Sleep promotes cellular repair, memory consolidation, immune
function, and restoration of energy.
D) Sleep is only necessary for children and older adults.
**Correct Answer: C**
**Rationale:** Sleep has multiple physiological and psychological
benefits: tissue repair, growth hormone release, immune system
strengthening, memory consolidation, and cognitive restoration. Sleep is
essential across the lifespan. Option A is incomplete; Option B is false;
Option D is false.

**3. A nurse is assessing a client's sleep patterns. The client reports
difficulty falling asleep. The nurse documents this as:**
A) Insomnia (difficulty initiating sleep)
, 4|Page
B) Hypersomnia
C) Narcolepsy
D) Sleep apnea
**Correct Answer: A**
**Rationale:** Insomnia can be difficulty falling asleep (sleep
initiation), difficulty staying asleep (sleep maintenance), or early
morning awakening. Hypersomnia is excessive daytime sleepiness.
Narcolepsy is sudden sleep attacks. Sleep apnea is cessation of breathing
during sleep.
---
**4. A client asks the nurse, "How many hours of sleep do I really
need?" Which response is most accurate?**
A) "All adults need exactly 8 hours of sleep per night."
B) "Sleep needs vary by individual, but most adults need 7-9 hours per
night."
C) "Older adults need less than 5 hours of sleep."
D) "Sleep needs decrease significantly after age 30."
**Correct Answer: B**
