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. A client with a tracheostomy is experiencing thick, tenacious secretions. Which intervention should the nurse implement first?

• A. Encourage fluid intake to thin secretions.
• B. Administer a mucolytic agent.
• C. Increase humidity in the client's room.
• D. Perform deep suctioning as needed.

Correct answer: C

Rationale: Increasing humidity in the client's room is the initial intervention for managing thick, tenacious secretions in a client with a tracheostomy. Adequate humidity helps to hydrate secretions, making them easier to clear, thus improving airway clearance. Encouraging fluid intake (Choice A) can be beneficial but is not the first-line intervention. Administering a mucolytic agent (Choice B) may be considered if increasing humidity alone is insufficient. Performing deep suctioning (Choice D) should be reserved for when other measures like increasing humidity have been ineffective.

3. The nurse is assessing a female client's blood pressure because she reported feeling dizzy. The blood pressure cuff is inflated to 140 mm Hg and as soon as the cuff is deflated a Korotkoff sound is heard. Which intervention should the nurse implement next?

• A. Wait 1 minute and palpate the systolic pressure before auscultating again.
• B. Increase the inflation pressure by 20 mm Hg and measure again.
• C. Switch to a larger cuff and repeat the measurement.
• D. Document the finding as normal.

Correct answer: A

Rationale: If a Korotkoff sound is heard immediately upon deflation, it may indicate an inaccurate reading. Waiting and palpating the systolic pressure can help confirm the accuracy of the measurement. Choice A is the correct intervention because it allows the nurse to ensure the accuracy of the blood pressure reading. Choice B is incorrect as increasing the inflation pressure is not necessary in this situation. Choice C is also incorrect as switching to a larger cuff is not warranted based on the information provided. Choice D is incorrect because documenting the finding as normal without further verification could lead to inaccurate information.

4. While caring for a toddler receiving oxygen (02) via face mask, the nurse observes that the child's lips and nares are dry and cracked. Which intervention should the nurse implement?

• A. Ask the mother what she usually uses on the child's lips and nose.
• B. Apply a petroleum jelly (Vaseline) to the child's nose and lips.
• C. Use a topical lidocaine (Zylocaine viscous) analgesic for cracked lips.
• D. Use a water-soluble lubricant on affected oral and nasal mucosa.

Correct answer: D

Rationale: A water-soluble lubricant is safe to use in conjunction with oxygen therapy, unlike petroleum jelly which is flammable.

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

• A. Serum creatinine of 2.0 mg/dl
• B. Serum potassium of 5.5 mEq/L
• C. Serum calcium of 8.0 mg/dl
• D. Hemoglobin of 12 g/dl

Correct answer: B

Rationale: A serum potassium level of 5.5 mEq/L is concerning in a client with ESRD scheduled for hemodialysis as it indicates hyperkalemia, which can lead to serious cardiac complications. Hyperkalemia can be exacerbated during hemodialysis, making it crucial to closely monitor serum potassium levels before the procedure. Monitoring serum creatinine, serum calcium, or hemoglobin levels is important in managing ESRD but is not the immediate focus before hemodialysis. Therefore, option B is the correct choice.
