1. The nurse is caring for a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value requires immediate intervention?

A. Serum potassium of 5.5 mEq/L
B. Serum creatinine of 2.5 mg/dL
C. Hemoglobin of 10 g/dL
D. White blood cell count of 10,000/mm³

Correct answer: A

Rationale: A serum potassium level of 5.5 mEq/L is most concerning in a client receiving erythropoietin therapy as it indicates hyperkalemia, requiring immediate intervention. High potassium levels can lead to severe cardiac arrhythmias and must be addressed promptly. The other laboratory values, though abnormal, do not present immediate life-threatening risks as hyperkalemia does.

2. A client with hyperthyroidism is admitted to the postoperative unit after subtotal thyroidectomy. Which of the client's serum laboratory values requires intervention by the nurse?

A. Total calcium 5.0 mg/dL.
B. Serum sodium 140 mEq/L.
C. Serum potassium 4.0 mEq/L.
D. Serum glucose 90 mg/dL.

Correct answer: A

Rationale: The correct answer is A. A calcium level of 5.0 mg/dL is critically low and could indicate hypoparathyroidism, a possible complication after thyroidectomy. Low calcium levels can lead to tetany, seizures, and cardiac dysrhythmias, requiring immediate intervention. Choices B, C, and D fall within the normal range and do not require immediate intervention in this scenario.

3. After multiple attempts to stop drinking, an adult male is admitted to the medical intensive care unit (MICU) with delirium tremens. He is tachycardic, diaphoretic, restless, and disoriented. Which finding indicates a life-threatening condition?

A. Widening QRS complexes and flat T waves
B. Tachycardia and elevated blood pressure
C. Restlessness and anxiety
D. Diaphoresis and dehydration

Correct answer: A

Rationale: The correct answer is A: Widening QRS complexes and flat T waves. In the context of an adult male with delirium tremens and symptoms like tachycardia, diaphoresis, restlessness, and disorientation, the presence of widening QRS complexes and flat T waves on an ECG suggests severe electrolyte imbalance, particularly hypokalemia. This severe electrolyte imbalance can lead to life-threatening arrhythmias such as ventricular tachycardia or fibrillation. Tachycardia and elevated blood pressure (choice B) can be expected in delirium tremens but do not directly indicate a life-threatening condition as widening QRS complexes and flat T waves do. Restlessness and anxiety (choice C) are common symptoms of delirium tremens but do not specifically signify a life-threatening condition. Diaphoresis and dehydration (choice D) are also common in delirium tremens but do not directly point towards a life-threatening electrolyte imbalance as widening QRS complexes and flat T waves do.

4. The nurse provides feeding tube instructions to the wife of a client with end-stage cancer. The client's wife performs a return demonstration correctly but begins crying and tells the nurse, 'I just don't think I can do this every day.' The nurse should direct further teaching strategies toward which learning domain?

A. Cognitive.
B. Affective.
C. Comprehension.
D. Psychomotor.

Correct answer: B

Rationale: The correct answer is B: Affective. The affective domain involves feelings and emotions, which are significant factors in the wife’s ability to cope and perform the required care. In this scenario, the wife's emotional response indicates a need for further support and teaching strategies to address her emotional concerns and build her confidence. Choices A, C, and D are incorrect because the issue at hand is not purely cognitive (knowledge), comprehension (understanding), or psychomotor (physical skills), but rather an emotional response that falls under the affective domain.

5. A 7-year-old boy is brought to the clinic because of facial edema. He reports that he has been voiding small amounts of dark, cloudy, tea-colored urine. The parents state that their son had a sore throat 2 weeks earlier, but it has resolved. After assessing the child's vital signs and weight, what intervention should the nurse implement next?

A. Perform an otoscopic examination
B. Measure the child's abdominal girth
C. Collect a urine specimen for routine urinalysis
D. Obtain a blood specimen for serum electrolytes

Correct answer: C

Rationale: Collecting a urine specimen for routine urinalysis is the next appropriate intervention. The symptoms described, including facial edema and tea-colored urine, are indicative of glomerulonephritis, a condition affecting the kidneys. A urine specimen can help assess renal function and the presence of blood and protein in the urine, which are common in glomerulonephritis. Performing an otoscopic examination (Choice A) is not relevant to the presenting symptoms. Measuring the child's abdominal girth (Choice B) is not necessary at this point as it does not directly address the urinary symptoms. Obtaining a blood specimen for serum electrolytes (Choice D) may provide information about electrolyte imbalances but is not the most appropriate initial step in this case.
