1. Which of the following is a factor that leads to increased risk for dehydration in the elderly?

• A. More insensible losses
• B. Increase in muscle mass
• C. Decline in kidney function
• D. Decrease in fat

Correct answer: C

Rationale: The correct answer is C: Decline in kidney function. As people age, their kidneys may not work as effectively in conserving water and concentrating urine, leading to a higher risk of dehydration. Choice A is incorrect because more insensible losses do not directly relate to an increased risk of dehydration in the elderly. Choice B, an increase in muscle mass, is not a factor that leads to dehydration. Choice D, a decrease in fat, is also not a direct factor contributing to dehydration in the elderly.

2. As you are walking in the park, a huge black Labrador runs up to you and places his paws on your shoulders. Immediately your heart starts racing, you feel palpitations, anxiety, and your hands become a little shaky. The nurse knows that this response is primarily caused by:

• A. cerebral cortex.
• B. somatic nervous system.
• C. limbic system.
• D. autonomic nervous system.

Correct answer: D

Rationale: The autonomic nervous system controls involuntary bodily functions like heart rate, respiration, and sweating. In the given scenario, the 'fight or flight' response is activated, leading to increased heart rate, palpitations, anxiety, and shaky hands. The cerebral cortex is involved in conscious thought processes and decision-making, not the immediate physiological response observed here. The somatic nervous system regulates voluntary movements, while the limbic system is responsible for emotions and memory, but the autonomic nervous system is primarily responsible for the physiological responses seen in this situation.

3. What adverse effect should the nurse monitor for during testosterone therapy in a male patient?

• A. Increased risk of cardiovascular events
• B. Increased risk of liver dysfunction
• C. Increased risk of prostate cancer
• D. Increased risk of bone fractures

Correct answer: A

Rationale: The correct answer is A: Increased risk of cardiovascular events. Testosterone therapy can lead to an increased risk of cardiovascular events, such as heart attacks and strokes. This is why nurses should monitor for signs and symptoms of cardiovascular issues during therapy. Choices B, C, and D are incorrect because testosterone therapy is not typically associated with an increased risk of liver dysfunction, prostate cancer, or bone fractures. It is crucial for nurses to prioritize cardiovascular monitoring in patients receiving testosterone therapy.

4. What is the best method to identify which type of stroke the client has?

• A. Obtain a 12-lead electrocardiogram STAT
• B. Obtain a blood specimen for electrolytes and blood cultures
• C. Ask the client about current allergies
• D. Obtain a cranial computerized tomogram (CT) STAT

Correct answer: D

Rationale: The correct answer is to obtain a cranial computerized tomogram (CT) STAT. A cranial CT scan is the best method to quickly identify the type of stroke a client is experiencing. Options A, B, and C are not appropriate for identifying the type of stroke as they are not specific to assessing stroke types.

5. Which of the following is a cause of edema?

• A. Decreased plasma proteins
• B. Hypotension
• C. Dehydration
• D. Polyuria

Correct answer: A

Rationale: The correct answer is A: Decreased plasma proteins. Edema can be caused by decreased plasma proteins, which reduce the osmotic pressure that keeps fluid in the blood vessels. Hypotension (choice B) is low blood pressure and is not a direct cause of edema. Dehydration (choice C) involves a lack of body fluid, but it is not a direct cause of edema. Polyuria (choice D) is excessive urination and not a direct cause of edema.
