1. What therapeutic effect is expected from tamsulosin (Flomax) in a male patient with benign prostatic hyperplasia (BPH)?

A. Relaxation of the muscles in the prostate and bladder neck, leading to improved urinary flow.
B. Increase in urine flow and relief of urinary obstruction.
C. Reduction in prostate size and improvement in urinary symptoms.
D. Improvement in erectile function.

Correct answer: A

Rationale: The correct answer is A: 'Relaxation of the muscles in the prostate and bladder neck, leading to improved urinary flow.' Tamsulosin is an alpha-blocker that specifically targets alpha-1 receptors in the prostate and bladder neck, causing relaxation of smooth muscles. This relaxation results in improved urinary flow and reduced symptoms of BPH. Choice B is incorrect because while tamsulosin does improve urinary flow, it does not directly increase urine flow. Choice C is incorrect because tamsulosin does not reduce prostate size. Choice D is incorrect as tamsulosin does not have a primary effect on erectile function.

2. What should the nurse teach the boy about anabolic steroid abuse?

A. The ability of anabolic steroids to build muscle is greatly exaggerated in the media.
B. Anabolic steroids are universally dangerous but are especially harmful to adolescents.
C. The muscle mass resulting from steroid use will atrophy unless doses are continually increased.
D. Anabolic steroids will reduce the boy's ability to perform weight-bearing exercise later in life.

Correct answer: B

Rationale: The correct answer is B because anabolic steroids are indeed universally dangerous, but they pose greater risks to adolescents due to their impact on growth and development. Choice A is incorrect because anabolic steroids do have the potential to build muscle mass, though not to the extent often portrayed in the media. Choice C is incorrect as muscle mass gained from steroid use may persist for a period even after discontinuation. Choice D is incorrect as anabolic steroids can enhance muscle performance initially, though long-term use can have adverse effects on health and not specifically on the ability to perform weight-bearing exercises.

3. A 70-year-old woman has difficulty with driving, and she has been frequently getting lost. Her husband said she has also been acting strangely and seems to want to sleep a lot. He said the other night she kept saying she was seeing animals such as lions in her room. He says her memory is not too bad, but he is very concerned about her health. Physical examination reveals an alert woman with stable vital signs. Bradykinesia and limb rigidity are noted. These findings are consistent with:

A. Alzheimer's disease.
B. vascular dementia.
C. dementia with Lewy bodies.
D. frontotemporal dementia.

Correct answer: C

Rationale: The correct answer is dementia with Lewy bodies (DLB). Hallucinations, parkinsonian symptoms (like bradykinesia and limb rigidity), and fluctuating cognition are characteristic of DLB. Alzheimer's disease (Choice A) typically presents with memory loss as a prominent feature. Vascular dementia (Choice B) is associated with a history of strokes and step-wise cognitive decline. Frontotemporal dementia (Choice D) often presents with changes in behavior and personality rather than the parkinsonian symptoms seen in this case.

4. Which of the following might result from severe diarrhea?

A. Respiratory acidosis
B. Metabolic alkalosis
C. Respiratory alkalosis
D. Metabolic acidosis

Correct answer: D

Rationale: The correct answer is D: Metabolic acidosis. Severe diarrhea can lead to metabolic acidosis because the loss of bicarbonate ions in the stool results in an overall decrease in the body's bicarbonate levels. Respiratory acidosis (choice A) is caused by retention of carbon dioxide, usually due to inadequate alveolar ventilation. Metabolic alkalosis (choice B) is characterized by elevated pH and bicarbonate levels, usually caused by conditions like vomiting. Respiratory alkalosis (choice C) is a condition of low blood carbon dioxide levels and high pH, often due to hyperventilation.

5. A male patient is concerned about the risk of prostate cancer while receiving finasteride (Proscar) for benign prostatic hyperplasia (BPH). What should the nurse explain about this risk?

A. Finasteride has been shown to lower the risk of developing prostate cancer.
B. Finasteride has no effect on the risk of developing prostate cancer.
C. Finasteride may increase the risk of developing prostate cancer, so regular screening is important.
D. Finasteride does not affect the risk of prostate cancer, so regular screening is unnecessary.

Correct answer: A

Rationale: The correct answer is A. Finasteride has been shown to lower the risk of developing prostate cancer. Studies have demonstrated that finasteride can reduce the incidence of prostate cancer. However, it is still recommended to have regular screening to monitor for any potential issues. Choice B is incorrect as finasteride has shown to have a positive effect on reducing prostate cancer risk. Choice C is inaccurate because finasteride decreases, not increases, the risk of prostate cancer. Choice D is incorrect as regular screening is still necessary despite the risk reduction associated with finasteride.
