Nursing Elites

1. Which word completes the sentence 'He was ____ by the unexpected turn of events.'?

• A. elated (joyful)
• B. bewildered (confused)
• C. vindicated (justified)
• D. apathetic (uninterested)

Correct answer: B

Rationale: In the sentence, 'He was bewildered by the unexpected turn of events,' the word 'bewildered' means confused, which is the most suitable choice to convey the feeling caused by unexpected events. 'Elated' means joyful, 'vindicated' means justified, and 'apathetic' means uninterested, making them less fitting in the context of being surprised or thrown off by unexpected events.

2. During micturition, the process involves a combination of:

• A. Gravity alone
• B. Voluntary muscle contractions only
• C. Involuntary muscle contractions only
• D. Both voluntary and involuntary muscle contractions

Correct answer: D

Rationale: During micturition, which is the process of urination, both voluntary and involuntary muscle contractions are involved. Voluntary muscle contractions include the relaxation of the external urethral sphincter, allowing the release of urine, while involuntary muscle contractions involve the detrusor muscle in the bladder contracting to expel urine. Choices A, B, and C are incorrect because micturition is not solely dependent on gravity, voluntary muscle contractions, or involuntary muscle contractions alone. The correct answer is D as both types of muscle contractions are necessary for the complete process of urination.

3. What do hair follicles house in the skin?

• A. Blood vessels (Blood vessels are not housed within hair follicles)
• B. Nerve endings (Nerve endings are present but not housed within hair follicles)
• C. Hair shafts and hair roots
• D. Sebaceous glands (These glands are often attached to hair follicles)

Correct answer: C

Rationale: Hair follicles are structures in the skin that contain the hair shaft (the visible part of the hair) and the hair root (the part of the hair beneath the skin). The hair shaft is the portion of the hair that is visible above the skin, while the hair root is the part that extends below the surface into the follicle. Therefore, the correct answer is that hair follicles house the hair shafts and hair roots. Choices A, B, and D are incorrect because blood vessels are not housed within hair follicles, nerve endings are present but not housed within hair follicles, and sebaceous glands are often attached to hair follicles but not housed within them.

4. What are the two primary functions of the respiratory system?

• A. Delivering nutrients and removing CO2
• B. Delivering O2 and removing CO2, maintaining blood pH
• C. Maintaining blood pH and delivering nutrients
• D. Delivering O2 and nutrients to the cells

Correct answer: B

Rationale: The correct answer is B. The respiratory system's primary functions include delivering oxygen (O2) to the body's cells for cellular respiration and removing carbon dioxide (CO2), thereby aiding in the maintenance of blood pH. These functions are crucial for gas exchange and the overall metabolic processes within the body. Choice A is incorrect as the respiratory system primarily delivers O2, not nutrients, and removes CO2, not delivering it. Choice C is incorrect as while the respiratory system helps maintain blood pH by removing CO2, it does not primarily deliver nutrients. Choice D is incorrect as it combines the functions of delivering O2 and nutrients, which are distinct roles of different systems in the body.

5. Which of the following facts would be the most relevant to include here?

• A. NO CHANGE; best as written
• B. was another activist group that
• C. had a lot of members that
• D. was another school that

Correct answer: B

Rationale: Option B provides relevant context by specifying that the BPP was another activist group. This clarification helps to establish a parallel between the BPP and the NAACP in terms of their function and purpose. Choice C is incorrect as the number of members is not the key point being compared in the sentence. Choice D is incorrect as it introduces an unrelated comparison involving schools, which is not relevant to the context provided in the sentence.
