Nursing Elites

1. The nurse is caring for a client with chronic heart failure who is receiving furosemide (Lasix). Which laboratory value requires immediate intervention?

• A. Serum potassium of 3.0 mEq/L
• B. Serum sodium of 135 mEq/L
• C. Serum creatinine of 1.8 mg/dL
• D. Blood glucose of 200 mg/dL

Correct answer: A

Rationale: A serum potassium level of 3.0 mEq/L is most concerning in a client receiving furosemide as it indicates hypokalemia, which requires immediate intervention. Hypokalemia can lead to serious cardiac arrhythmias, which can be life-threatening. Serum sodium of 135 mEq/L and serum creatinine of 1.8 mg/dL are within normal ranges and do not require immediate intervention in this case. Blood glucose of 200 mg/dL is elevated but does not pose an immediate threat to the client's life in the context of heart failure and furosemide therapy.

2. The client with end-stage renal disease (ESRD) is scheduled for hemodialysis. Which laboratory value is most concerning?

• A. Serum potassium of 6.0 mEq/L
• B. Serum creatinine of 2.5 mg/dL
• C. Serum calcium of 8.0 mg/dL
• D. Hemoglobin of 10 g/dL

Correct answer: A

Rationale: A serum potassium level of 6.0 mEq/L is most concerning in a client with ESRD scheduled for hemodialysis as it indicates hyperkalemia, which can lead to serious cardiac complications such as arrhythmias and cardiac arrest. Immediate intervention is required to lower potassium levels. Choice B, serum creatinine of 2.5 mg/dL, is elevated but expected in ESRD due to impaired kidney function. Choice C, serum calcium of 8.0 mg/dL, is within the normal range and not typically a priority in this situation. Choice D, hemoglobin of 10 g/dL, is slightly low but not an immediate concern for a client scheduled for hemodialysis unless significantly lower and causing severe symptoms.

3. A client with a history of chronic heart failure is admitted with shortness of breath and crackles in the lungs. Which laboratory value should be closely monitored?

• A. Serum creatinine of 2.0 mg/dL
• B. Serum sodium of 135 mEq/L
• C. Serum potassium of 5.5 mEq/L
• D. Blood glucose of 150 mg/dL

Correct answer: C

Rationale: A serum potassium level of 5.5 mEq/L should be closely monitored in a client with chronic heart failure as it may indicate hyperkalemia, requiring intervention. Hyperkalemia can lead to life-threatening cardiac arrhythmias in patients with heart failure. Serum creatinine (Choice A) is important to monitor for kidney function but is not the priority in this case. Serum sodium (Choice B) and blood glucose (Choice D) levels are not typically the primary focus when assessing a client with heart failure presenting with respiratory symptoms and crackles in the lungs.

4. A client with a spinal cord injury at the T1 level is admitted with a suspected deep vein thrombosis (DVT) in the right leg. Which intervention should the nurse implement first?

• A. Administer prescribed anticoagulant therapy
• B. Place the client on bedrest
• C. Elevate the client's right leg
• D. Apply compression stockings to the right leg

Correct answer: B

Rationale: The correct answer is to place the client on bedrest. Placing the client on bedrest is the priority intervention as it helps prevent the risk of embolization from the DVT, which could lead to a life-threatening pulmonary embolism. Administering anticoagulant therapy, elevating the client's right leg, or applying compression stockings are important interventions in managing DVT but should come after ensuring the client is on bedrest to prevent the dislodgment of the clot.

5. A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with pneumonia. Which assessment finding requires immediate intervention?

• A. Oxygen saturation of 90%
• B. Respiratory rate of 24 breaths per minute
• C. Use of accessory muscles
• D. Inspiratory crackles

Correct answer: C

Rationale: The correct answer is C: Use of accessory muscles. In a client with COPD and pneumonia, the use of accessory muscles indicates increased work of breathing and may signal respiratory failure. Immediate intervention is necessary to prevent further deterioration of the respiratory status. Choice A, an oxygen saturation of 90%, though low, may not require immediate intervention as it is above the typical threshold for initiating supplemental oxygen. Choice B, a respiratory rate of 24 breaths per minute, falls within the normal range for an adult and may not be an immediate cause for concern. Choice D, inspiratory crackles, are indicative of fluid in the lungs but may not require immediate intervention unless accompanied by other concerning signs like decreased oxygen saturation or increased respiratory distress.
