Nursing Elites

1. The client with chronic obstructive pulmonary disease (COPD) is receiving supplemental oxygen. Which laboratory value is most concerning?

• A. Serum sodium of 135 mEq/L
• B. Serum potassium of 4.0 mEq/L
• C. Serum bicarbonate of 18 mEq/L
• D. Serum glucose of 300 mg/dl

Correct answer: C

Rationale: A serum bicarbonate level of 18 mEq/L is concerning in a client with COPD receiving supplemental oxygen as it indicates metabolic acidosis, which can occur due to the body compensating for chronic respiratory acidosis. This condition requires immediate intervention to restore the acid-base balance. Choice A, serum sodium of 135 mEq/L, is within normal range (135-145 mEq/L) and not directly related to COPD or oxygen therapy. Choice B, serum potassium of 4.0 mEq/L, falls within the normal range (3.5-5.0 mEq/L) and is not typically affected by COPD or oxygen therapy. Choice D, serum glucose of 300 mg/dl, though elevated, is not directly related to COPD or oxygen therapy and would require management but is not the most concerning value in this scenario.

2. A client with chronic kidney disease (CKD) is admitted with hyperkalemia. Which laboratory value is most concerning?

• 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 concerning in a client with CKD as it indicates hyperkalemia, which requires immediate intervention to prevent cardiac complications. Hyperkalemia can lead to life-threatening arrhythmias, particularly in patients with impaired kidney function. Serum sodium, creatinine, and blood glucose levels, while important, are not as acutely dangerous as severe hyperkalemia in this context.

3. Which instruction is most important for a client who receives a new plan of care to treat osteoporosis?

• A. Start a weight-bearing exercise plan.
• B. Increase consumption of foods rich in calcium.
• C. Arrange a bone density test every year.
• D. Stay upright after taking the medication.

Correct answer: D

Rationale: The correct answer is D: 'Stay upright after taking the medication.' This instruction is crucial for clients receiving medications like bisphosphonates to prevent esophageal irritation or erosion. While weight-bearing exercises (choice A) are important for bone health, staying upright after medication intake takes precedence. Increasing calcium-rich foods (choice B) is beneficial but not the most important immediate instruction. Scheduling bone density tests (choice C) is necessary for monitoring osteoporosis but is not as critical as staying upright after medication.

4. A male client with impaired renal function who takes ibuprofen daily for chronic arthritis is showing signs of gastrointestinal (GI) bleeding. After administering IV fluids and a blood transfusion, his blood pressure is 100/70 mm Hg, and his renal output is 20 ml/hour. Which intervention should the nurse include in his care plan?

• A. Maintain the client NPO during the diuresis phase.
• B. Evaluate daily serial renal laboratory studies for progressive elevations.
• C. Observe the urine character for sedimentation and cloudy appearance.
• D. Monitor for the onset of polyuria greater than 150 ml/hour.

Correct answer: B

Rationale: In this scenario, the correct intervention for the nurse to include in the care plan is to evaluate daily serial renal laboratory studies for progressive elevations. This is crucial in monitoring renal function and detecting any worsening renal impairment. Option A is not directly related to managing renal function in this case. Option C focuses more on urinary characteristics rather than renal function monitoring. Option D addresses polyuria, which is an excessive urine output, but it does not specifically address the need for evaluating renal laboratory studies for progressive elevations.

5. A client with end-stage renal disease (ESRD) is scheduled for hemodialysis. Which laboratory value should be reported to the healthcare provider before the procedure?

• A. Serum creatinine of 2.5 mg/dL
• B. Serum potassium of 6.5 mEq/L
• C. Serum calcium of 8 mg/dL
• D. Serum bicarbonate of 24 mEq/L

Correct answer: B

Rationale: The correct answer is B. A serum potassium level of 6.5 mEq/L is dangerously high and should be reported before hemodialysis to prevent cardiac complications. High potassium levels can lead to life-threatening arrhythmias. Serum creatinine (Choice A) is elevated in renal dysfunction but not the most critical value to report before hemodialysis. Serum calcium (Choice C) and serum bicarbonate (Choice D) levels are within normal limits and are not immediate concerns before hemodialysis.
