Correct Answer: D

Rationale: The correct finding the nurse should report to the provider is decreased breath sounds in the right lower lobe. This can indicate a respiratory infection or atelectasis in clients with COPD, requiring further evaluation and intervention. Choice A, an oxygen saturation of 91%, although slightly lower than normal, does not necessarily require immediate reporting unless the client's baseline is significantly higher. Choice B, the use of pursed-lip breathing, is actually a beneficial technique for clients with COPD to improve oxygenation and reduce shortness of breath, so it does not need reporting. Choice C, a productive cough with green sputum, can be common in clients with COPD and may indicate an infection, but it is not as concerning as decreased breath sounds in a specific lung lobe which may signify a more acute issue.

Correct Answer: A

Rationale: Corrected Rationale: Potassium levels should be monitored closely in a patient receiving digoxin to avoid hypokalemia. Digoxin can increase the risk of developing life-threatening arrhythmias in the presence of low potassium levels. Monitoring sodium, calcium, or glucose levels is not specifically necessary for patients on digoxin, making choices B, C, and D incorrect.

Correct Answer: C

Rationale: The correct answer is C: 'Use a blood pressure cuff that fits snugly around the arm.' Using a properly fitting cuff is essential for accurate blood pressure measurements. Choice A is incorrect because the timing of medication administration should be individualized and not specified in the question. Choice B is incorrect as checking blood pressure once a week may not provide sufficient monitoring for a client with hypertension. Choice D is incorrect because stopping medication abruptly once blood pressure is normal can lead to rebound hypertension and complications.

Correct Answer: B

Rationale: The correct answer is B: Hemoglobin 12 g/dL. In a client with heart failure, a decrease in hemoglobin levels can indicate anemia, which can exacerbate heart failure symptoms. Reporting this finding to the provider is crucial for appropriate management. Choice A, Potassium 4.0 mEq/L, is within the normal range (3.5-5.0 mEq/L) and does not typically require immediate reporting. Choice C, BUN 18 mg/dL, and Choice D, Sodium 137 mEq/L, are also within normal ranges and not directly related to heart failure management. Therefore, the hemoglobin level is the most critical finding to report in this scenario.

Correct Answer: A

Rationale: The correct answer is Lisinopril. Lisinopril is an ACE inhibitor commonly prescribed to patients with hypertension to manage their blood pressure. Metformin is used to treat type 2 diabetes, not hypertension (choice B). Atorvastatin is a statin used to lower cholesterol levels, not primarily prescribed for hypertension (choice C). Aspirin is used for its antiplatelet effects and in preventing cardiovascular events, but it is not a first-line treatment for hypertension (choice D). Therefore, Lisinopril is the most suitable choice for a patient with hypertension.
