Nursing Elites

1. The healthcare provider prescribes an IV solution of isoproterenol (Isuprel) 1 mg in 250 ml of D5W at 300 mcg/hour. The nurse should program the infusion pump to deliver how many ml/hour?

• A. 50 ml/hour
• B. 25 ml/hour
• C. 75 ml/hour
• D. 100 ml/hour

Correct answer: C

Rationale: To calculate the infusion rate, convert 1 mg to 1,000 mcg (1 mg = 1,000 mcg) and then use the formula D/H x Q, where D is the desired dose, H is the dose on hand, and Q is the quantity of solution. In this case, it would be 300 mcg/hour / 1,000 mcg x 250 ml = 75 ml/hour. Therefore, the nurse should program the infusion pump to deliver 75 ml/hour. Choice A (50 ml/hour), Choice B (25 ml/hour), and Choice D (100 ml/hour) are incorrect as they do not correspond to the calculated rate of 75 ml/hour.

2. A client with a history of chronic kidney disease (CKD) is scheduled for a CT scan with contrast. Which laboratory value should the nurse review before the procedure?

• A. Serum creatinine
• B. Blood urea nitrogen (BUN)
• C. Serum potassium
• D. Serum glucose

Correct answer: A

Rationale: The correct answer is A: Serum creatinine. Before a CT scan with contrast, the nurse should review the serum creatinine level. This is crucial in patients with CKD because contrast agents can potentially worsen kidney function and lead to contrast-induced nephropathy. Monitoring serum creatinine helps assess kidney function and determine the risk of complications. Choices B, C, and D are less relevant in this scenario. Blood urea nitrogen (BUN) is another marker of kidney function, but serum creatinine is a more specific indicator. Serum potassium levels are important in assessing electrolyte balance but are not directly related to the risk of contrast-induced nephropathy. Serum glucose levels are not typically a primary concern before a CT scan with contrast in a patient with CKD.

3. During a clinic visit, a client with a kidney transplant asks, 'What will happen if chronic rejection develops?' Which response is best for the nurse to provide?

• A. Dialysis would need to be resumed if chronic rejection becomes a reality.
• B. Immunosuppressive therapy would be intensified.
• C. A second transplant would be scheduled immediately.
• D. We would monitor your kidney function closely.

Correct answer: A

Rationale: The best response for the nurse to provide is that dialysis would need to be resumed if chronic rejection becomes a reality. Chronic rejection of a transplanted kidney can lead to kidney failure, necessitating the need for dialysis until another transplant is possible. Choice B is incorrect because although immunosuppressive therapy may be adjusted, the immediate concern is the potential need for dialysis. Choice C is incorrect because scheduling a second transplant immediately is not typically the first step following chronic rejection. Choice D is also incorrect as close monitoring of kidney function is essential but does not address the immediate need for dialysis if chronic rejection occurs.

4. When a male Korean-American client looks away when asked by the nurse to describe his problem, what is the best initial nursing action?

• A. Ask for assistance from social services to find a Korean interpreter.
• B. Establish indirect eye contact with the client.
• C. Allow several minutes for the client to respond.
• D. Repeat the question using simpler language.

Correct answer: C

Rationale: In this scenario, the best initial nursing action is to allow several minutes for the client to respond. This approach respects the cultural norms of the client, as in some cultures, direct eye contact may be perceived as disrespectful or intrusive. By giving the client time to gather his thoughts and respond at his own pace, the nurse promotes effective communication and demonstrates cultural sensitivity. Asking for assistance from social services to find a Korean interpreter (Choice A) may be necessary for further communication but is not the best initial action. Establishing indirect eye contact (Choice B) may still make the client uncomfortable. Repeating the question using simpler language (Choice D) may not address the underlying cultural aspect affecting the client's response.

5. A client with type 1 diabetes is admitted with diabetic ketoacidosis (DKA). Which laboratory value requires immediate intervention?

• A. Serum glucose of 300 mg/dl
• B. Serum potassium of 5.5 mEq/L
• C. Serum bicarbonate of 18 mEq/L
• D. Serum sodium of 135 mEq/L

Correct answer: C

Rationale: A serum bicarbonate level of 18 mEq/L requires immediate intervention in a client with diabetic ketoacidosis (DKA). A low serum bicarbonate level indicates metabolic acidosis, which can be life-threatening. This condition needs urgent correction to restore acid-base balance. Serum glucose of 300 mg/dl, serum potassium of 5.5 mEq/L, and serum sodium of 135 mEq/L are abnormal values, but they do not pose an immediate threat to the client's life compared to the metabolic acidosis indicated by the low serum bicarbonate level.
