A patient with a history of venous thromboembolism is being considered for hormone replacement therapy (HRT). What should the nurse discuss with the patient regarding the risks of HRT?
- A. Discuss the potential for increased bone density.
- B. Discuss the potential for an increased risk of cardiovascular events.
- C. Discuss the potential for a reduced risk of breast cancer.
- D. Discuss the potential for improved mood and energy levels.
Correct Answer: B
Rationale: The correct answer is B because hormone replacement therapy (HRT) is associated with an increased risk of cardiovascular events, including venous thromboembolism. Patients with a history of venous thromboembolism are at higher risk, so discussing this potential risk is crucial. Choice A, increased bone density, is not a major risk of HRT. Choice C, reduced risk of breast cancer, is not a common discussion point regarding HRT risks. Choice D, improved mood and energy levels, is more related to the benefits of HRT rather than its risks.

A report comes back indicating that muscular atrophy has occurred. A nurse recalls that muscular atrophy involves a decrease in muscle cell size:
- A. Number
- B. Size
- C. Vacuoles
- D. Lipofuscin
Correct Answer: B
Rationale: The correct answer is B: Size. Muscular atrophy is characterized by a reduction in the size of muscle cells. This decrease in size can be due to various factors such as disuse, aging, or disease. Choice A, Number, is incorrect because muscular atrophy does not involve a decrease in the number of muscle cells but rather their size. Choice C, Vacuoles, is incorrect as vacuoles are not directly related to the definition of muscular atrophy. Choice D, Lipofuscin, is incorrect as lipofuscin is a pigment associated with aging and has no direct connection to the decrease in muscle cell size seen in muscular atrophy.
A person is given an attenuated antigen as a vaccine. When the person asks what was given in the vaccine, how should the nurse respond? The antigen is:
- A. Alive, but less infectious
- B. Mutated, but highly infectious
- C. Normal, but not infectious
- D. Inactive, but infectious
Correct Answer: A
Rationale: An attenuated antigen used in a vaccine is alive but less infectious, aiming to stimulate an immune response. Choice B is incorrect because an attenuated antigen is not highly infectious. Choice C is incorrect as the antigen is intentionally altered to be less infectious. Choice D is incorrect as an attenuated antigen is not infectious.
A male patient with benign prostatic hyperplasia (BPH) is prescribed finasteride (Proscar). What should the nurse include in the patient education?
- A. The medication is expected to reduce the size of the prostate, which should improve urinary symptoms over time.
- B. The medication will improve symptoms within a few days.
- C. The medication will cure BPH after treatment is complete.
- D. The medication may cause erectile dysfunction as a side effect.
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
While in an induced coma for 3 weeks, a badly burned firefighter awakens and thanks his son for singing Happy Birthday to him a week earlier. Which part of the brain is responsible for allowing him to hear and comprehend while comatose?
- A. Cerebellum
- B. Thalamus
- C. Temporal lobe
- D. Occipital lobe
Correct Answer: C
Rationale: The temporal lobe is responsible for processing auditory information, allowing the patient to hear and comprehend while in a coma. The cerebellum is primarily associated with coordination and balance, not auditory processing. The thalamus serves as a relay station for sensory information but is not specifically responsible for auditory processing. The occipital lobe is mainly involved in processing visual information, not auditory functions.
A patient is prescribed dutasteride (Avodart) for benign prostatic hyperplasia (BPH). What outcome should the nurse expect to observe if the drug is having the desired effect?
- A. Decreased size of the prostate gland
- B. Increased urinary output
- C. Increased urine flow
- D. Decreased blood pressure
Correct Answer: A
Rationale: The correct answer is A: Decreased size of the prostate gland. Dutasteride is a medication used for BPH to reduce the size of the prostate gland, thereby improving urinary flow and decreasing symptoms. Choice B, increased urinary output, is incorrect as dutasteride primarily targets the size of the prostate gland rather than directly affecting urinary output. Choice C, increased urine flow, is related to the expected outcome of dutasteride therapy but is not as direct as the reduction in the size of the prostate gland. Choice D, decreased blood pressure, is not an expected outcome of dutasteride therapy for BPH.
