WGU Pathophysiology Final Exam Questions

Question 1 of 5

The unique clinical presentation of a 3-month-old infant in the emergency department leads the care team to suspect botulism. Which assessment question posed to the parents is likely to be most useful in the differential diagnosis?

Correct Answer: B

Rationale: The correct answer is B. Poor feeding and constipation are common early symptoms of infant botulism, which is caused by a neurotoxin that impairs muscle function. Option A is unrelated to the presentation of botulism. Option C does not directly relate to the symptoms of botulism. Option D is more indicative of respiratory issues rather than the constellation of symptoms seen in botulism.

Question 2 of 5

A patient is prescribed finasteride (Proscar) for benign prostatic hyperplasia (BPH). What outcome should the nurse expect to observe?

Correct Answer: A

Rationale: The correct answer is A: Decreased urinary frequency and urgency. Finasteride is expected to decrease urinary frequency and urgency in patients with BPH by reducing prostate size. It works by inhibiting the enzyme that converts testosterone to dihydrotestosterone, which helps shrink the prostate gland. Choices B, C, and D are incorrect. Finasteride does not increase prostate size, blood pressure, or the risk of kidney stones.

Question 3 of 5

A patient is being treated with hormone replacement therapy (HRT) for menopausal symptoms. What are the risks associated with long-term HRT that the nurse should discuss with the patient?

Correct Answer: A

Rationale: The correct answer is A. Long-term HRT is associated with increased risks of cardiovascular events and breast cancer. These risks should be discussed with the patient to ensure they are informed about the potential adverse effects. Choice B is incorrect because HRT does not decrease the risk of osteoporosis; in fact, it may increase the risk of certain conditions like cardiovascular events. Choice C is incorrect as HRT is associated with an increased risk of venous thromboembolism, not a decreased risk. Choice D is incorrect because while HRT may have positive effects like improving symptoms of menopause, it is not primarily indicated for improving mood and energy levels.

Question 4 of 5

The unique clinical presentation of a 3-month-old infant in the emergency department leads the care team to suspect botulism. Which assessment question posed to the parents is likely to be most useful in the differential diagnosis?

Correct Answer: B

Rationale: The correct answer is B. Poor feeding and constipation are common early symptoms of infant botulism, which is caused by a neurotoxin that impairs muscle function. Option A is unrelated to the presentation of botulism. Option C does not directly relate to the symptoms of botulism. Option D is more indicative of respiratory issues rather than the constellation of symptoms seen in botulism.

Question 5 of 5

An older adult patient comes to the clinic complaining of not being able to do what he used to be able to. You know that normal changes associated with aging include:

Correct Answer: B

Rationale: Normal changes associated with aging include a slowed metabolic rate and decreased brain weight. Option A, 'Improved blood flow,' is incorrect as aging is generally associated with reduced vascular health rather than improved blood flow. Option D, 'Improved nerve fiber conduction,' is incorrect as aging typically leads to a decline in nerve function rather than improvement.
