Nursing Elites

1. A client with chronic obstructive pulmonary disease (COPD) is admitted with an exacerbation. Which laboratory value is most concerning?

• A. Serum potassium of 6.5 mEq/L
• B. Serum bicarbonate of 18 mEq/L
• C. Serum glucose of 350 mg/dl
• D. Serum sodium of 135 mEq/L

Correct answer: A

Rationale: A serum potassium level of 6.5 mEq/L is concerning in a client with COPD exacerbation as it may lead to life-threatening arrhythmias, requiring immediate intervention. Hyperkalemia can cause cardiac arrhythmias, which pose a significant risk to the patient's life. Options B, C, and D are not typically associated with immediate life-threatening risks in the context of a COPD exacerbation.

2. In a client with cirrhosis admitted with jaundice and ascites, which laboratory value is most concerning?

• A. Serum bilirubin of 3.0 mg/dl
• B. Serum albumin of 3.0 g/dl
• C. Serum ammonia level of 80 mcg/dl
• D. Serum sodium level of 135 mEq/L

Correct answer: C

Rationale: A serum ammonia level of 80 mcg/dl is most concerning in a client with cirrhosis as it may indicate hepatic encephalopathy, requiring immediate intervention. Elevated ammonia levels are associated with impaired liver function and can lead to mental status changes. Serum bilirubin (Choice A) is elevated in cirrhosis but not as concerning for acute intervention as high ammonia levels. Serum albumin (Choice B) and serum sodium (Choice D) levels are important in cirrhotic patients but are not as directly associated with hepatic encephalopathy as ammonia levels.

3. A client with chronic kidney disease (CKD) is scheduled for a hemodialysis session. Which laboratory value should the nurse monitor closely?

• A. Serum potassium
• B. Serum creatinine
• C. Serum sodium
• D. Serum chloride

Correct answer: C

Rationale: The correct answer is C: Serum sodium. In a client with chronic kidney disease (CKD) scheduled for hemodialysis, monitoring serum sodium levels closely is essential. Hemodialysis can cause rapid shifts in sodium levels, leading to electrolyte imbalances. While serum potassium (choice A) is important to monitor in CKD, it is not the most crucial before hemodialysis. Serum creatinine (choice B) is an indicator of kidney function but is not the most immediate concern before hemodialysis. Serum chloride (choice D) is not typically the primary electrolyte of concern in CKD patients before hemodialysis.

4. A male client reports the onset of numbness and tingling in his fingers and around his mouth. Which lab test is important for the nurse to review before contacting the healthcare provider?

• A. Capillary glucose
• B. Urine specific gravity
• C. Serum calcium
• D. White blood cell count

Correct answer: C

Rationale: The correct answer is C: Serum calcium. Numbness and tingling in the fingers and around the mouth are indicative of hypocalcemia. Serum calcium levels should be reviewed as they play a crucial role in diagnosing and managing hypocalcemia. Option A, capillary glucose, is not relevant to the symptoms described. Option B, urine specific gravity, is not typically used to assess numbness and tingling. Option D, white blood cell count, is unrelated to the symptoms presented by the client.

5. A client with diabetes mellitus is admitted with a blood glucose level of 640 mg/dl and is unresponsive. Which intervention should the nurse implement first?

• A. Administer 50% dextrose IV push
• B. Administer IV fluids as prescribed
• C. Check the client's blood glucose level
• D. Prepare the client for immediate dialysis

Correct answer: B

Rationale: Administering IV fluids as prescribed is the priority intervention in a client with a blood glucose level of 640 mg/dl and unresponsiveness. Severe hyperglycemia can lead to dehydration and electrolyte imbalances, and administering IV fluids can help manage hyperglycemia and prevent further complications. Administering dextrose IV push (Choice A) can exacerbate hyperglycemia in this scenario. Checking the client's blood glucose level (Choice C) is important but not the immediate priority when the client is unresponsive. Immediate dialysis (Choice D) is not indicated as the first intervention for hyperglycemia.
