Nursing Elites

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

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

Correct answer: C

Rationale: Before a CT scan with contrast, the nurse should review the serum creatinine level. This is crucial in assessing kidney function because contrast agents can potentially worsen renal function, leading to contrast-induced nephropathy. Monitoring serum creatinine helps in identifying patients at risk and taking necessary precautions. Serum potassium (Choice A) is important in conditions like hyperkalemia but is not the priority before a contrast CT scan. Blood urea nitrogen (BUN) (Choice B) is another renal function test but is not as specific as serum creatinine for assessing kidney function. Serum glucose (Choice D) is important in monitoring blood sugar levels, especially in diabetic patients, but it is not directly related to the risk of contrast-induced nephropathy in this scenario.

2. 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.

3. A client with chronic liver disease is admitted with ascites and jaundice. Which assessment finding is most concerning?

• A. Enlarged spleen
• B. Increased abdominal girth
• C. Yellowing of the skin
• D. Confusion and altered mental status

Correct answer: D

Rationale: Confusion and altered mental status are concerning in a client with chronic liver disease, as they may indicate hepatic encephalopathy, a serious complication that requires immediate intervention. Enlarged spleen (choice A) can be a common finding in liver disease due to portal hypertension but may not be as acute as hepatic encephalopathy. Increased abdominal girth (choice B) is typically seen in ascites, which is already present in this client. Yellowing of the skin (choice C) is a manifestation of jaundice, also a known symptom in liver disease but not as acute as confusion and altered mental status.

4. In caring for a client with a PCA infusion of morphine sulfate through the right cephalic vein, the nurse assesses that the client is lethargic with a blood pressure of 90/60, pulse rate of 118 beats per minute, and respiratory rate of 8 breaths per minute. What assessment should the nurse perform next?

• A. Note the appearance and patency of the client's peripheral IV site.
• B. Palpate the volume of the client's right radial pulse.
• C. Auscultate the client's breath sounds bilaterally.
• D. Observe the amount and dose of morphine in the PCA pump syringe.

Correct answer: D

Rationale: In this scenario, the nurse is dealing with a lethargic client with concerning vital signs after a PCA infusion of morphine sulfate. The next assessment the nurse should perform is to observe the amount and dose of morphine in the PCA pump syringe. This is crucial to evaluate for possible overdose, as the client's symptoms could be indicative of opioid toxicity. Checking the morphine amount and dose will help the nurse adjust the treatment accordingly. Choices A, B, and C do not directly address the potential cause of the client's lethargy and abnormal vital signs related to the morphine infusion.

5. A client with a history of severe rheumatoid arthritis is receiving a corticosteroid. Which assessment finding should the nurse report to the healthcare provider immediately?

• A. Blood glucose level of 180 mg/dL
• B. Weight gain of 2 pounds in 24 hours
• C. Blood pressure of 140/90 mmHg
• D. Increased joint pain

Correct answer: C

Rationale: Elevated blood pressure (140/90 mmHg) is a significant finding that the nurse should report immediately. Hypertension can be a severe side effect of corticosteroid therapy, especially in clients with preexisting conditions like rheumatoid arthritis. It requires prompt intervention to prevent complications such as cardiovascular events. The other options, while important to monitor, are not as critical as elevated blood pressure in this context. A blood glucose level of 180 mg/dL may indicate hyperglycemia, weight gain could be due to fluid retention, and increased joint pain is expected in a client with severe rheumatoid arthritis.
