Correct Answer is D

Explanation

Choice A rationale
Frothy sputum is more commonly associated with left-sided heart failure, where fluid backs up into the lungs. It is not a typical finding in right-sided heart failure.
Choice B rationale

Orthopnea, or difficulty breathing while lying flat, is more commonly associated with left-sided heart failure. Right-sided heart failure primarily affects the systemic circulation.
Choice C rationale
Dyspnea, or shortness of breath, can occur in both left-sided and right-sided heart failure. However, it is more prominently associated with left-sided heart failure.
Choice D rationale
Peripheral edema, or swelling in the legs and ankles, is a common finding in right-sided heart failure. It occurs due to the backup of blood in the systemic circulation, leading to fluid accumulation in the tissues.

A. Sweating. B. Tachycardia. C. Polydipsia. D. Polyuria.

Correct Answer is D

Explanation

Choice A rationale
Sweating is incorrect. While sweating can be a symptom of hypoglycemia, it is not a specific indicator of effective diabetes management.
Choice B rationale
Tachycardia is incorrect. Tachycardia can occur during hypoglycemia due to the body’s release of adrenaline, but it is not a specific indicator of effective diabetes management.
Choice C rationale
Polydipsia is incorrect. Polydipsia, or excessive thirst, is a symptom of hyperglycemia, indicating poor blood sugar control.
Choice D rationale
Polyuria is correct. Polyuria, or frequent urination, is a symptom of hyperglycemia. Effective diabetes management aims to reduce hyperglycemia and its symptoms.
