Zorluk: KolayReduction of Risk Potential

An older adult client with a history of heart failure is prescribed a daily dose of oral furosemide. The most recent comprehensive metabolic panel reveals a serum potassium level of 2.62.6 mEq/L (2.62.6 mmol/L). Which action should the practical nurse take?

  1. A
    Administer the scheduled furosemide and document the potassium result in the electronic health record.
  2. Withhold the furosemide and immediately report the potassium level to the supervising registered nurse.Cevap
  3. C
    Verify the client's identity using only the room number before administering the medication.
  4. D
    Accept a verbal order to administer potassium chloride via intravenous push to correct the deficit.

Cevap

The nurse must withhold the diuretic medication and immediately notify the supervising registered nurse about the critically low potassium level.
The normal serum potassium level is 3.53.5 to 5.05.0 mEq/L (3.53.5 to 5.05.0 mmol/L). A level of 2.62.6 mEq/L (2.62.6 mmol/L) indicates severe hypokalemia. Furosemide is a potassium-wasting loop diuretic. Administering it would further lower the potassium level, placing the client at high risk for lethal cardiac dysrhythmias. The practical nurse must prioritize client safety by withholding the dose and escalating the critical finding immediately.

Adım Adım Çözüm

1
Interpret the serum potassium laboratory result.
The value of 2.62.6 mEq/L is significantly below the normal adult range of 3.53.5 to 5.05.0 mEq/L, indicating severe hypokalemia.
Recognizing abnormal laboratory values is the first essential step in clinical risk reduction.
2
Analyze the relationship between the prescribed medication and the critical laboratory value.
Furosemide is a loop diuretic that causes the kidneys to excrete potassium. Giving this medication will worsen the client's already severe hypokalemia.
Understanding medication mechanism of action prevents the administration of contraindicated drugs.
3
Determine the safest nursing intervention within the practical nurse scope of practice.
The safest action is to withhold the dose and escalate the critical finding to the registered nurse or healthcare provider.
The practical nurse must act promptly to prevent harm and communicate critical data to the supervising team.
