Pathophysiology Practice Questions

1. Multiple sclerosis manifests as asymmetrical and in different parts of the body because:

Correct answer: A

Rationale: The correct answer is A. Multiple sclerosis is characterized by the immune system attacking the myelin sheath in the central nervous system. This attack leads to patchy damage on the myelin sheath, resulting in asymmetrical neurological symptoms. Choices B, C, and D are incorrect because they do not accurately describe the pathophysiology of multiple sclerosis. In multiple sclerosis, it is the autoreactive lymphocytes that target and damage the myelin sheath, not acetylcholine receptors, T lymphocytes, or cortical motor cells.

2. What is the primary therapeutic action of tamsulosin (Flomax) in a male patient with benign prostatic hyperplasia (BPH)?

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, a medication commonly prescribed for BPH, works by selectively blocking alpha-1 adrenergic receptors in the prostate, causing relaxation of smooth muscles in the prostate and bladder neck. This relaxation reduces the constriction in these areas, improving urinary flow and reducing symptoms such as hesitancy, urgency, frequency, and weak stream. Choice B is incorrect because tamsulosin does not directly reduce the size of the prostate. Choice C is incorrect as tamsulosin primarily acts by relaxing muscles rather than directly increasing urine flow. Choice D is incorrect as tamsulosin is not indicated for improving erectile function.

3. A patient has been prescribed an estrogen-progestin oral contraceptive. The nurse should emphasize that the risk of thrombophlebitis is most likely in patients who:

Correct answer: B

Rationale: The correct answer is B: Smoke cigarettes. Smoking is a significant risk factor for thrombophlebitis, especially when combined with estrogen-progestin contraceptives. Choice A, being diabetic, does not directly increase the risk of thrombophlebitis in this context. Choice C, having a history of hypertension, is not a primary risk factor for thrombophlebitis. Choice D, being older than 40, is not the most likely factor associated with an increased risk of thrombophlebitis in patients taking estrogen-progestin oral contraceptives.

4. Which of the following would the nurse see in a client with thrombocytopenia?

Correct answer: A

Rationale: Thrombocytopenia is characterized by a decreased platelet cell count, leading to an increased risk of bleeding. Therefore, the correct answer is A. Choice B, a decreased white blood cell count, is not typically associated with thrombocytopenia. Choice C, an increased red blood cell count, is not a characteristic finding in thrombocytopenia. Choice D, an increased platelet cell count, is the opposite of what is observed in thrombocytopenia.

5. A client on an acute medicine unit of a hospital with a diagnosis of small bowel obstruction is reporting intense, diffuse pain in her abdomen. Which physiologic phenomenon is most likely contributing to her complaint?

Correct answer: C

Rationale: Visceral pain is associated with distension, ischemia, and inflammation of internal organs. In the case of a small bowel obstruction, the intense, diffuse pain reported by the client is likely due to the distension and ischemia of the small bowel. Somatic pain (Choice A) would be more localized and sharp, typically arising from the parietal peritoneum. Referred pain (Choice B) is pain perceived at a site distant from the actual pathology. Neuropathic pain (Choice D) involves dysfunction or damage to the nervous system and is not typically associated with the described physiologic phenomenon of distension and ischemia in the context of a small bowel obstruction.
