Midwifery Exam Questions Questions
Question 1 of 5
The progression of coronary artery plaque formation can lead to a variety of pathologic conditions. When subtotal plaque disruption occurs resulting in vasoconstriction, platelet activation, and embolization, it most commonly causes which clinical phenomenon?
Correct Answer: C
Rationale: The correct answer is C: Transmural myocardial infarction. Subtotal plaque disruption leads to vasoconstriction, platelet activation, and embolization, causing complete occlusion of a coronary artery. This results in ischemia of the entire thickness of the myocardial wall, leading to transmural myocardial infarction. Endothelial cell dysfunction (A) is an early event in atherosclerosis but does not directly result from subtotal plaque disruption. Prinzmetal's angina (B) is caused by transient coronary artery spasm rather than plaque disruption. Non-ST elevation myocardial infarction (D) involves incomplete blockage of a coronary artery and typically does not result from subtotal plaque disruption.
Question 2 of 5
The AGACNP is rounding on a patient following splenectomy for idiopathic thrombocytopenia purpura. On postoperative day 2, a review of the laboratory studies is expected to reveal
Correct Answer: B
Rationale: Step 1: Post-splenectomy, platelet count typically drops temporarily, leading to a risk of bleeding. Step 2: To compensate, the body increases hemoglobin (Hgb) levels to maintain oxygen-carrying capacity. Step 3: Therefore, on postoperative day 2, an increased Hgb level is expected. Summary: A is incorrect because MCV is not typically affected in this scenario. C is incorrect because platelet count usually decreases post-splenectomy. D is incorrect as albumin levels are not directly impacted by splenectomy for ITP.
Question 3 of 5
T. O. is a 44-year-old female patient who presents for evaluation of sudden, severe upper abdominal pain. She is clear about the onset, which was profound and occurred approximately one hour ago. She denies that the onset had any relationship to food or eating, and she denies nausea or vomiting. On examination, she is lying on her right side with her hips and knees flexed to draw her knees to her chest. Vital signs are stable, but examination reveals involuntary guarding. The abdomen is painful and tympanic to percussion in all quadrants. CBC reveals a white blood cell count of 15,600L. The AGACNP suspects
Correct Answer: B
Rationale: The correct answer is B: Acute pancreatitis. The clinical presentation of sudden, severe upper abdominal pain not related to food intake, along with the patient's position (lying on right side with hips and knees flexed), and presence of involuntary guarding suggest acute pancreatitis. The elevated white blood cell count indicates an inflammatory process. Dissecting aortic aneurysm (A) typically presents with abrupt, severe chest or back pain radiating to the abdomen, with signs of shock. Perforated peptic ulcer (C) presents with sudden, severe abdominal pain often related to food intake, with signs of peritonitis. Mallory-Weiss tear (D) presents with hematemesis after forceful or prolonged vomiting.
Question 4 of 5
A patient with chronic hepatic encephalopathy is being discharged home. Discharge teaching centers upon long-term management strategies to prevent ammonia accumulation. Teaching for this patient includes instruction about
Correct Answer: C
Rationale: The correct answer is C: Protein intake of 50 g daily. In hepatic encephalopathy, reducing protein intake helps decrease ammonia production. Excessive ammonia leads to neurological symptoms. Lactulose (choice A) is correct for hepatic encephalopathy as it helps eliminate ammonia through the gut. Spironolactone (choice B) is a diuretic and not indicated for hepatic encephalopathy. Zolpidem (choice D) is a sleep aid and not relevant to managing ammonia accumulation. In summary, choice C is correct because it directly targets the underlying issue of ammonia accumulation in hepatic encephalopathy, while the other choices do not address this specific concern.
Question 5 of 5
In which form of hypospadias should circumcision be deferred in order to preserve the prepuce for later surgical repair?
Correct Answer: A
Rationale: In ventral displacement hypospadias, circumcision should be deferred to preserve prepuce for later surgical repair as the prepuce is needed for reconstruction. The prepuce can be used as a tissue graft to correct the hypospadias. In proximal displacement, the urethral opening is closer to the scrotum, making prepuce preservation less critical. Midscrotal hypospadias and meatus proximal to the corona do not typically involve prepuce preservation for surgical repair.
