Nursing Elites

1. A client with chronic kidney disease (CKD) is scheduled for a renal biopsy. Which laboratory value should the nurse review before the procedure?

• A. Serum potassium
• B. Serum creatinine
• C. Hemoglobin
• D. White blood cell count

Correct answer: B

Rationale: Before a renal biopsy, the nurse should review the serum creatinine level. Serum creatinine is a key indicator of kidney function. In clients with chronic kidney disease (CKD), monitoring creatinine levels is crucial as elevated levels may indicate worsening kidney function, which could impact the safety and outcome of the biopsy. Hemoglobin (choice C) is important for assessing oxygen-carrying capacity but is not directly related to the kidney biopsy procedure. Serum potassium (choice A) is important to monitor in CKD but is not specifically crucial before a renal biopsy. White blood cell count (choice D) is more relevant for assessing infection or inflammation, which is not the primary concern before a renal biopsy.

2. A client with liver cirrhosis is admitted with ascites and jaundice. Which assessment finding is most concerning?

• A. Serum albumin of 3.0 g/dL
• B. Bilirubin of 3.0 mg/dL
• C. Ammonia level of 80 mcg/dL
• D. Prothrombin time of 18 seconds

Correct answer: C

Rationale: An ammonia level of 80 mcg/dL is elevated and concerning in a client with liver cirrhosis, as it may indicate hepatic encephalopathy. Elevated ammonia levels can lead to cognitive impairment, altered mental status, and even coma. Serum albumin, bilirubin, and prothrombin time are also important markers in liver cirrhosis but are not as directly associated with the risk of hepatic encephalopathy as elevated ammonia levels.

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 atrial fibrillation is receiving digoxin (Lanoxin) and warfarin (Coumadin). Which assessment finding should the nurse report to the healthcare provider immediately?

• A. Heart rate of 58 beats per minute
• B. Presence of a new murmur
• C. INR of 2.5
• D. Blood pressure of 110/70 mmHg

Correct answer: B

Rationale: The correct answer is B. The presence of a new murmur in a client with atrial fibrillation may indicate a valvular problem or other complications, requiring immediate reporting. A heart rate of 58 beats per minute is within the normal range for some individuals with atrial fibrillation, so it is not an immediate concern. An INR of 2.5 is within the therapeutic range for a client on warfarin, indicating appropriate anticoagulation. A blood pressure of 110/70 mmHg is also within the normal range and does not pose an immediate threat to the client's health.

5. A client with type 2 diabetes is admitted with hyperglycemic hyperosmolar syndrome (HHS). Which laboratory value is most concerning?

• A. Serum glucose of 300 mg/dL
• B. Blood pressure of 140/90 mmHg
• C. Serum osmolarity of 320 mOsm/kg
• D. Serum pH of 7.30

Correct answer: C

Rationale: In a client with hyperglycemic hyperosmolar syndrome (HHS), a serum osmolarity of 320 mOsm/kg is the most concerning laboratory value. This high osmolarity indicates severe dehydration, which can lead to serious complications. Elevated serum glucose levels (choice A) are expected in HHS but do not directly reflect dehydration. Blood pressure (choice B) and serum pH (choice D) are important parameters to monitor but are not the most concerning values in HHS compared to serum osmolarity.
