Correct Answer: B

Rationale: The correct answer is B: inadequate supply of oxygen to the myocardium. Angina pectoris is chest pain or discomfort caused by reduced blood flow to the heart muscle. This lack of oxygenated blood supply to the myocardium leads to ischemia, resulting in the characteristic chest pain. Choice A is incorrect as it refers to a decrease in alveolar surface area for gas exchange, which is related to conditions like emphysema, not angina. Choice C is incorrect as it pertains to pulmonary circulation, not coronary circulation. Choice D is incorrect as an increase in alveolar surface area would not be a cause of angina pectoris.

Correct Answer: C

Rationale: The correct initial treatment for stage IV ovarian cancer is major surgery (Choice C). This is because at this advanced stage, surgery is typically performed to debulk the tumor and remove as much cancerous tissue as possible, followed by chemotherapy to target any remaining cancer cells. Radiation therapy (Choice A) is not typically the initial treatment for ovarian cancer. Chemotherapy (Choice B) is often used in combination with surgery, but surgery is usually the first line of treatment for stage IV disease. Choosing no treatment (Choice D) would be detrimental as the cancer is advanced and requires immediate intervention.

Correct Answer: B

Rationale: The correct answer is B: Tachycardia. Levothyroxine is a synthetic form of thyroid hormone used to treat hypothyroidism. If the dose is too high, it can lead to symptoms of hyperthyroidism, including tachycardia (rapid heartbeat). This is because an excess of thyroid hormone can increase the heart rate. Dysuria (choice A) is not a common adverse effect of levothyroxine. Leg cramps (choice C) are more commonly associated with electrolyte imbalances. Blurred vision (choice D) is not a typical adverse effect of levothyroxine.

Correct Answer: D

Rationale: The correct answer is D, a behavior change. Urinary retention in older adults with a neurologic deficit can manifest as a behavior change, such as increased agitation, confusion, or restlessness due to discomfort from the inability to empty the bladder. Amnesia (A) is memory loss and not directly related to urinary retention. Hypertension (B) and hypotension (C) are related to blood pressure regulation and are not specific signs of urinary retention. In contrast, a behavior change (D) is a common and characteristic sign indicating urinary retention in this population.

Correct Answer: A

Rationale: Step-by-step rationale: 1. The nurse should clarify discrepancies of assessment data with the client to ensure accurate information. 2. The client's denial of breathing problems conflicts with physical signs, indicating a potential lack of awareness or reluctance to disclose symptoms. 3. By clarifying with the client, the nurse can address any misunderstandings or encourage honest communication. 4. This approach promotes client-centered care and ensures a comprehensive understanding of the client's health status. Summary: - Choice A is correct as it addresses the need to clarify discrepancies with the client for accurate assessment. - Choice B is incorrect as validation with the healthcare team may not provide insight into the client's perception. - Choice C is incorrect as it does not address the need to resolve conflicting assessment data. - Choice D is incorrect as family input may not provide accurate information if the client denies symptoms.
