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. Which nursing intervention has the highest priority for a multigravida who delivered twins and is at risk for postpartum hemorrhage?

• A. Maintain cold packs on the perineum for 24 hours.
• B. Assess the client's pain level frequently.
• C. Observe for appropriate interaction with the infants.
• D. Assess fundal tone and lochia flow.

Correct answer: D

Rationale: Assessing fundal tone and lochia flow is crucial in the early detection and prevention of postpartum hemorrhage. Fundal tone helps identify uterine atony, a common cause of postpartum hemorrhage, while monitoring lochia flow can indicate excessive bleeding. Cold packs on the perineum, although helpful for pain and swelling, are not the priority in this situation. Pain assessment and observing interactions with infants are important but secondary to assessing for signs of postpartum hemorrhage.

3. The nurse is assessing a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value should be closely monitored?

• A. Serum potassium level
• B. Hemoglobin level
• C. White blood cell count
• D. Serum sodium level of 135 mEq/L

Correct answer: A

Rationale: The correct answer is A: Serum potassium level. In clients receiving erythropoietin therapy for chronic kidney disease, monitoring serum potassium levels is crucial due to the risk of developing hyperkalemia. Erythropoietin therapy can stimulate red blood cell production, leading to an increase in potassium levels. Monitoring potassium levels helps prevent complications associated with hyperkalemia, such as cardiac arrhythmias. Choices B, C, and D are incorrect because while hemoglobin levels are relevant for assessing the effectiveness of erythropoietin therapy, monitoring potassium levels is more critical due to the potential adverse effects of elevated potassium levels in CKD patients on this therapy.

4. A client with chronic kidney disease (CKD) is admitted with hyperkalemia. Which laboratory value requires immediate intervention?

• A. Serum potassium of 6.5 mEq/L
• B. Serum sodium of 135 mEq/L
• C. Serum creatinine of 2.0 mg/dL
• D. Blood glucose of 150 mg/dL

Correct answer: A

Rationale: A serum potassium level of 6.5 mEq/L is most concerning in a client with CKD as it indicates severe hyperkalemia, requiring immediate intervention. Hyperkalemia can lead to life-threatening cardiac arrhythmias. Serum sodium levels within the normal range (135 mEq/L) are not immediately concerning. Serum creatinine of 2.0 mg/dL may indicate impaired kidney function but does not require immediate intervention for hyperkalemia. Blood glucose of 150 mg/dL is within normal limits and does not directly correlate with hyperkalemia in this scenario.

5. A client with hypertension receives a prescription for enalapril, an angiotensin-converting enzyme (ACE) inhibitor. Which instruction should the nurse include in the medication teaching plan?

• A. Increase intake of potassium-rich foods.
• B. Report increased bruising or bleeding.
• C. Stop medication if a cough develops.
• D. Limit intake of leafy green vegetables.

Correct answer: B

Rationale: The correct instruction for the nurse to include in the medication teaching plan is to 'Report increased bruising or bleeding.' ACE inhibitors can cause thrombocytopenia, which lowers platelet count and increases the risk of bruising and bleeding. Choice A is incorrect because while ACE inhibitors may cause potassium levels to increase, the instruction should not be to increase intake of potassium-rich foods without healthcare provider guidance. Choice C is incorrect because a cough is a common side effect of ACE inhibitors due to bradykinin accumulation, and stopping the medication abruptly is not recommended without consulting the healthcare provider. Choice D is incorrect because there is no need to limit intake of leafy green vegetables specifically with ACE inhibitors; however, consistent intake of vitamin K-rich foods is recommended to maintain a stable INR for clients taking anticoagulants.
