WGU Pathophysiology Final Exam

1. A 9-year-old girl has a diffuse collection of symptoms that are indicative of deficits in endocrine and autonomic nervous system control. She also suffers from persistent fluid and electrolyte imbalances. On which aspect of the nervous system listed below would her health care providers focus their diagnostic efforts?

Correct answer: C

Rationale: The correct answer is C: The hypothalamus. The hypothalamus plays a central role in regulating endocrine and autonomic functions, including fluid and electrolyte balance. In this case, the girl's symptoms of deficits in endocrine and autonomic nervous system control, along with fluid and electrolyte imbalances, point towards dysfunction in the hypothalamus. Choices A, B, and D are incorrect because the thalamus is mainly involved in sensory relay, the pituitary gland regulates various hormones but is controlled by the hypothalamus, and the midbrain is responsible for motor control and arousal, not endocrine or autonomic functions.

2. A patient with a history of breast cancer is being prescribed tamoxifen (Nolvadex). What should the nurse include in the patient education about the use of this medication?

Correct answer: A

Rationale: The correct answer is A. Tamoxifen is known to increase the risk of venous thromboembolism, a serious side effect. Patients should be educated about the signs and symptoms of blood clots, such as swelling, pain, or redness in the affected limb, and the importance of seeking immediate medical attention if they occur. Choice B is incorrect because hot flashes are a common side effect of tamoxifen but not a critical concern like venous thromboembolism. Choice C is incorrect as tamoxifen is not associated with a decreased risk of osteoporosis. Choice D is incorrect because while weight gain can occur with tamoxifen, it is not as crucial to educate the patient about as the risk of venous thromboembolism.

3. A patient's current medical condition is suggestive of impaired erythropoiesis. Which of the following laboratory studies would be most clinically relevant in diagnosing this health problem?

Correct answer: B

Rationale: In this scenario, where impaired erythropoiesis is suspected, the most clinically relevant laboratory studies would focus on red blood cell parameters. Therefore, assessing RBC count, hemoglobin levels, and hematocrit values would provide direct insights into erythropoiesis. Choices A, C, and D are not directly related to erythropoiesis assessment. White blood cell count with a differential is more indicative of immune response and infection. INR and aPTT are coagulation studies, while d-dimer and C-reactive protein levels are more associated with inflammation and thrombotic events.

4. When teaching a patient about the use of finasteride (Proscar) for benign prostatic hyperplasia (BPH), what should the nurse emphasize about the expected outcomes of this therapy?

Correct answer: B

Rationale: The correct answer is B. The effects of finasteride in treating BPH may take several weeks or months to become noticeable as it works by shrinking the prostate gland over time. Therefore, patients should be informed that improvement in symptoms may not be immediate. Choice A is incorrect because improvement in symptoms is not expected within a few days. Choice C is incorrect as immediate improvement in urinary flow is not typical with finasteride. Choice D is incorrect because finasteride manages BPH symptoms but does not cure the condition.

5. A patient with osteoporosis is prescribed raloxifene (Evista). What is the primary therapeutic action of this medication?

Correct answer: A

Rationale: The correct answer is A. Raloxifene works by decreasing bone resorption and increasing bone density. This helps in preventing further bone loss and reducing the risk of fractures in patients with osteoporosis. Choice B is incorrect because raloxifene does not stimulate the formation of new bone, but rather helps to maintain existing bone mass. Choice C is incorrect as raloxifene does not directly increase calcium absorption in the intestines. Choice D is also incorrect as raloxifene does not increase the excretion of calcium through the kidneys.
