1. A client is admitted with a diagnosis of diabetic ketoacidosis (DKA). Which clinical finding is most concerning to the nurse?
- A. Kussmaul respirations
- B. Blood glucose level of 300 mg/dl
- C. Serum potassium of 3.2 mEq/L
- D. Positive urine ketones
Correct answer: C
Rationale: The correct answer is C: Serum potassium of 3.2 mEq/L. A low serum potassium level in a client with DKA is concerning due to the risk of cardiac arrhythmias. Kussmaul respirations (choice A) are a compensatory mechanism for metabolic acidosis in DKA. A blood glucose level of 300 mg/dl (choice B) is elevated but expected in DKA. Positive urine ketones (choice D) are a classic finding in DKA and not as concerning as low serum potassium.
2. A client with chronic kidney disease (CKD) is receiving erythropoietin therapy. Which laboratory value should the nurse monitor closely?
- A. Serum potassium
- B. Hemoglobin
- C. White blood cell count
- D. Serum creatinine
Correct answer: A
Rationale: The correct answer is A: Serum potassium. When a client with chronic kidney disease is receiving erythropoietin therapy, monitoring serum potassium closely is essential. Erythropoietin therapy can lead to increased red blood cell production, which may cause potassium levels to rise, potentially resulting in hyperkalemia. Monitoring potassium levels helps prevent complications associated with hyperkalemia. Choices B, C, and D are incorrect because they are not directly impacted by erythropoietin therapy in the context of CKD.
3. The nurse is caring for 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 calcium level
Correct answer: A
Rationale: The correct answer is A: Serum potassium level. When a client with chronic kidney disease is receiving erythropoietin therapy, monitoring serum potassium levels is crucial due to the risk of developing hyperkalemia. Erythropoietin can stimulate red blood cell production, leading to an increase in potassium levels. Monitoring potassium helps prevent complications associated with hyperkalemia, such as cardiac arrhythmias. Choices B, C, and D are incorrect because while hemoglobin levels are relevant in assessing the effectiveness of erythropoietin therapy, monitoring potassium levels is more critical in this scenario.
4. A client with cirrhosis is admitted with ascites and jaundice. Which assessment finding is most concerning?
- A. Peripheral edema
- B. Confusion and altered mental status
- C. Increased abdominal girth
- D. Yellowing of the skin
Correct answer: B
Rationale: Confusion and altered mental status are concerning signs of hepatic encephalopathy in a client with cirrhosis. Hepatic encephalopathy is a serious complication of liver disease that requires immediate intervention. Peripheral edema may be present due to fluid accumulation, increased abdominal girth can indicate ascites which is common in cirrhosis, and yellowing of the skin is a typical manifestation of jaundice in liver dysfunction, all of which are important but not as immediately concerning as signs of hepatic encephalopathy.
5. The nurse discovers that an elderly client with no history of cardiac or renal disease has an elevated serum magnesium level. To further investigate the cause of this electrolyte imbalance, what information is most important for the nurse to obtain from the client's medical history?
- A. Frequency of laxative use for chronic constipation
- B. Dietary intake of magnesium-rich foods
- C. Use of magnesium-containing supplements
- D. History of alcohol use
Correct answer: A
Rationale: The correct answer is A. Frequent use of magnesium-containing laxatives can lead to hypermagnesemia, particularly in elderly clients. Option B, dietary intake of magnesium-rich foods, may contribute to elevated serum magnesium levels but is less likely the cause in this scenario. Option C, the use of magnesium-containing supplements, can also contribute to hypermagnesemia but is not as common in elderly clients without a history of using such supplements. Option D, history of alcohol use, is less relevant to the development of elevated serum magnesium levels compared to laxative use for chronic constipation.
