HESI 799 RN Exit Exam

Correct Answer: B

Rationale: Evaluating daily renal laboratory studies is crucial in this scenario. The client has impaired renal function, recent GI bleeding, and is at risk for further kidney damage due to ibuprofen use. Monitoring renal labs helps assess kidney function and detect any progressive elevations, guiding further interventions. Option A is not directly related to renal function monitoring. Option C focuses more on urine appearance than renal function assessment. Option D mentions polyuria, which is excessive urine output, but the question describes a client with reduced renal output.

Correct Answer: D

Rationale: In this situation, the client's capillary refill of 8 seconds is the assessment finding that warrants immediate intervention by the nurse. A capillary refill greater than 3 to 5 seconds indicates poor perfusion, which could be a sign of inadequate circulation and oxygenation. Checking capillary refill is a quick and useful way to assess peripheral perfusion. Bruises on arms and legs may indicate a bleeding disorder but are not as urgent as addressing poor perfusion. A round and tight abdomen could suggest ascites, which is already known in this case. Pitting edema in lower legs is a common finding in malnutrition and ascites but does not require immediate intervention as poor capillary refill does.

Correct Answer: C

Rationale: The correct answer is C: Peaked T waves on the ECG. In hyperkalemia, elevated potassium levels can affect the heart's electrical activity, leading to changes on the ECG such as peaked T waves. This finding is concerning as it can progress to serious cardiac arrhythmias, including ventricular tachycardia and fibrillation. Bradycardia (choice A) and decreased deep tendon reflexes (choice D) are not typically associated with hyperkalemia. While muscle weakness (choice B) can occur in hyperkalemia due to its effect on neuromuscular function, the most concerning assessment finding indicating the need for immediate intervention in this scenario is peaked T waves on the ECG.

Correct Answer: B

Rationale: Serum troponin is the most specific and sensitive indicator of myocardial infarction. Troponin levels rise within 3-4 hours after myocardial damage, peak at 10-24 hours, and remain elevated for up to 10-14 days. Creatine kinase (CK) and myoglobin can also be elevated in myocardial infarction, but troponin is more specific to cardiac muscle damage. C-reactive protein (CRP) is a marker of inflammation and is not specific for myocardial infarction.
