Correct Answer: D

Rationale: A productive cough with pink, frothy sputum is a classic sign of pulmonary edema, indicating fluid in the lungs. This finding requires immediate intervention to prevent respiratory compromise and worsening of the condition. Peripheral edema (Choice A) is a manifestation of heart failure but is not as urgent as addressing pulmonary edema. Oxygen saturation of 88% (Choice B) is low and requires attention, but the pink, frothy sputum signifies acute respiratory distress. Jugular vein distention (Choice C) can be seen in heart failure, but the immediate concern in this scenario is addressing the pulmonary edema to ensure adequate gas exchange and oxygenation.

Correct Answer: D

Rationale: The correct answer is to advise the client to begin a low sodium diet immediately. High sodium intake can contribute to elevated blood pressure levels. By reducing sodium intake, blood pressure can be effectively lowered. Option A, participating in an exercise program, is beneficial for overall health but may not provide immediate impact on blood pressure. Option B, obtaining blood pressure daily for 2 weeks, may not address the underlying cause or provide immediate intervention. Option C, increasing dietary intake of omega-3 fatty acids, though beneficial for heart health, may not have an immediate impact on lowering blood pressure compared to reducing sodium intake.

Correct Answer: C

Rationale: In a client with COPD receiving oxygen therapy, an effective response is indicated by a respiratory rate of 20 breaths per minute. This suggests that the client is effectively oxygenating while maintaining an appropriate respiratory rate. Choices A, B, and D are incorrect because expectorating secretions easily, having an oxygen saturation of 92%, and arterial blood gases showing a pH of 7.35 are not specific indicators of the effectiveness of oxygen therapy in COPD. Oxygen saturation of 92% may still be suboptimal in COPD, and arterial blood gases showing a pH of 7.35 may not necessarily reflect the overall effectiveness of oxygen therapy.

Correct Answer: B

Rationale: A reduction in fasting blood glucose levels indicates the effectiveness of the diabetes management education provided. Monitoring blood glucose levels is a crucial aspect of diabetes management, and a decrease in average readings signifies improvement in managing blood sugar levels. Choices A, C, and D are not direct outcome evaluations related to the effectiveness of the education provided in managing diabetes. Parking convenience, attendance, and teaching strategies are not direct indicators of the impact on the clients' health outcomes.

Correct Answer: D

Rationale: After hemodialysis, muscle cramps can indicate an electrolyte imbalance, such as low potassium or magnesium levels, which requires immediate intervention to prevent potential complications like cardiac arrhythmias. Weight gain of 1 pound, dizziness, and fatigue are common post-hemodialysis symptoms that may not necessarily require immediate intervention unless they are severe or persisting.
