Correct Answer: B

Rationale: Scheduling weekly home visits to monitor hCG levels is critical for early detection of choriocarcinoma, a potential complication of GTD. Choice A is incorrect because a home pregnancy test is not the appropriate method to monitor for choriocarcinoma. Choice C is less frequent than necessary for close monitoring. Choice D is incorrect as chemotherapy administration should be based on confirmed diagnosis and treatment plan, not initiated during the first home visit.

Correct Answer: A

Rationale: The most important intervention for the nurse to implement during the initial visit is to determine how the client is cared for when the caregiver is not present. This is crucial for ensuring continuous and adequate care, especially for a bed-bound client with multiple sclerosis who relies heavily on the caregiver. While developing a client needs assessment (choice B) and evaluating the caregiver's ability (choice C) are important, understanding the care plan in the caregiver's absence takes precedence. Reviewing daily interventions with the caregiver (choice D) is valuable but not as critical as knowing the care plan during the caregiver's absence.

Correct Answer: C

Rationale: The correct answer is C because diets rich in milk and cream stimulate gastric acid secretion, which can exacerbate a duodenal ulcer. Therefore, it is essential to avoid foods that are rich in milk and cream. Choice A is incorrect because switching to decaffeinated coffee and tea does not address the issue of avoiding milk and cream products. Choice B is incorrect because while eating frequent small meals can help with discomfort, it does not address the specific issue of avoiding milk and cream. Choice D is incorrect as it does not address the need to avoid milk and cream products.

Correct Answer: A

Rationale: Administering oxygen therapy is the priority intervention in managing chest pain in a client with a history of myocardial infarction. Oxygen helps improve oxygenation to the heart muscle, which is crucial in reducing further damage. Obtaining an electrocardiogram (ECG) is important to assess for changes indicative of myocardial infarction, but providing oxygen takes precedence as it directly addresses the physiological need for oxygen. Administering nitroglycerin and aspirin are important interventions but are typically implemented after oxygen therapy to address vasodilation and antiplatelet effects, respectively.

Correct Answer: A

Rationale: The correct answer is A: Irregular pulse. An irregular pulse may indicate an arrhythmia, which could be exacerbated by atenolol, a beta-blocker used to treat angina pectoris. Atenolol works by slowing the heart rate, so if the patient already has an irregular pulse, it could worsen with the medication. Tachycardia (choice B) would actually be an expected finding in a patient with angina pectoris, and atenolol is used to help reduce the heart rate in such cases. Chest pain (choice C) is a symptom that atenolol is meant to alleviate, so it would not be a reason to withhold the medication. Urinary frequency (choice D) is not directly related to the administration of atenolol for angina pectoris and would not require immediate reporting to the healthcare provider.
