Final Exam Pathophysiology

1. A child is experiencing difficulty with chewing and swallowing. The nurse knows that which cells may be innervating specialized gut-related receptors that provide taste and smell?

Correct answer: C

Rationale: The correct answer is C: Special visceral afferent cells. These cells are responsible for innervating taste and smell receptors related to the gut. Special somatic afferent fibers (choice A) are involved in sensations like touch and proprioception, not taste and smell. General somatic afferents (choice B) carry sensory information from the skin and musculoskeletal system, not taste and smell. General visceral afferent neurons (choice D) transmit sensory information from internal organs, but not specifically related to taste and smell sensations.

2. A patient is being treated with raloxifene (Evista) for osteoporosis. What should the nurse teach the patient about this medication?

Correct answer: C

Rationale: The correct answer is C. Raloxifene is a selective estrogen receptor modulator (SERM) used to prevent bone loss. It should be taken with food to reduce gastrointestinal side effects, not on an empty stomach. Choices A and B are incorrect because raloxifene is indeed a SERM that prevents bone loss, but it does not directly work by increasing bone formation or decreasing bone resorption. Choice D is incorrect as weight gain and fluid retention are not common side effects of raloxifene.

3. When evaluating the success of adding raltegravir to the drug regimen of a 42-year-old female patient with HIV, which laboratory value should the nurse prioritize?

Correct answer: C

Rationale: The correct answer is C: The patient's viral load. In HIV management, monitoring the viral load is crucial to assess the effectiveness of antiretroviral therapy. A decrease in viral load indicates the treatment's success in controlling the HIV infection. Choices A, B, and D are less relevant in this context. C-reactive protein levels and erythrocyte sedimentation rate are markers of inflammation and non-specific indicators of infection, not specifically for HIV. CD4 count is important but not as immediate for evaluating the response to the newly added medication compared to monitoring the viral load.

4. What is the etiology and most likely treatment for myasthenia gravis in a 22-year-old female college student?

Correct answer: B

Rationale: Myasthenia gravis is characterized by a decline in functioning acetylcholine receptors rather than autoimmune destruction of skeletal muscle cells (Choice A), cerebellar lesions (Choice C), or excess acetylcholinesterase production (Choice D). The most likely treatment for myasthenia gravis involves corticosteroids to reduce inflammation and intravenous immunoglobulins to block the antibodies attacking acetylcholine receptors. Intensive physical therapy and anabolic steroids are not primary treatments for myasthenia gravis.

5. Rhabdomyolysis can result in serious complications. In addition to muscle pain and weakness, a patient will complain of:

Correct answer: C

Rationale: Dark urine is a classic symptom of rhabdomyolysis. When muscle breakdown occurs, myoglobin is released into the bloodstream and filtered by the kidneys, leading to dark urine. Paresthesias (choice A) refer to abnormal sensations like tingling or numbness and are not typically associated with rhabdomyolysis. Bone pain (choice B) is not a prominent symptom of rhabdomyolysis. Diarrhea (choice D) is not a common complaint in rhabdomyolysis cases and is not directly related to muscle breakdown.
