Pathophysiology Practice Exam

1. How will taking an oral contraceptive affect the physiologically of an insulin-dependent diabetic patient?

Correct answer: C

Rationale: Taking an oral contraceptive can lead to an increase in blood glucose levels in insulin-dependent diabetic patients. This occurs due to the hormonal changes induced by the contraceptive, which can impact insulin sensitivity. Therefore, diabetic patients need to closely monitor their blood glucose levels when starting an oral contraceptive to prevent complications. The other choices are incorrect as oral contraceptives do not typically lead to an increase in heart rate, risk of hypoglycemia, or risk of metabolic alkalosis in this context.

2. A patient has been prescribed mifepristone (RU-486) to terminate a pregnancy. How does this drug achieve its therapeutic effect?

Correct answer: A

Rationale: Mifepristone (RU-486) functions by inhibiting the action of progesterone, a hormone crucial for maintaining pregnancy. By blocking progesterone, mifepristone disrupts the uterine environment necessary for pregnancy continuation, ultimately leading to termination. Choice B is incorrect because mifepristone does not increase estrogen levels; instead, it acts on progesterone. Choice C is incorrect as mifepristone's mechanism does not involve altering the uterine lining to prevent implantation. Choice D is incorrect because mifepristone does not directly stimulate uterine contractions; its primary action is through progesterone inhibition.

3. A nurse practitioner is assessing a 7-year-old boy who has been brought to the clinic by his mother, who is concerned about her son's increasingly frequent, severe headaches. Which of the nurse's questions is least likely to yield data that will confirm or rule out migraines as the cause of his problem?

Correct answer: C

Rationale: The correct answer is C. In assessing a child for migraines, asking about food allergies is least likely to yield data that will confirm or rule out migraines as the cause of his headaches. Food allergies are unrelated to the typical symptoms and triggers of migraines, such as family history, associated symptoms like nausea and vomiting, and pain-free intervals between headaches. Therefore, in this scenario, focusing on food allergies is less relevant for identifying migraines as the cause of the boy's headaches.

4. 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.

5. A patient is starting on alendronate (Fosamax) for osteoporosis. What instructions should the nurse provide to ensure the effectiveness of the medication?

Correct answer: A

Rationale: The correct answer is to take alendronate with a full glass of water and remain upright for at least 30 minutes. This is essential to prevent esophageal irritation and ensure proper absorption. Choice B is incorrect because taking alendronate at bedtime can increase the risk of esophageal irritation due to lying down. Choice C is incorrect as taking alendronate with milk can reduce its absorption. Choice D is incorrect because alendronate should be taken on an empty stomach to enhance its effectiveness.
