1. During shift report, the central electrocardiogram (EKG) monitoring system alarms. Which client alarm should the nurse investigate first?
- A. Respiratory apnea of 30 seconds
- B. Oxygen saturation rate of 88%
- C. Eight premature ventricular beats every minute
- D. Disconnected monitor signal for the last 6 minutes.
Correct answer: A
Rationale: The correct answer is A: Respiratory apnea of 30 seconds. Respiratory apnea indicates a cessation of breathing, which is a life-threatening emergency requiring immediate intervention. Priority should be given to assessing and managing airway, breathing, and circulation. Option B, oxygen saturation rate of 88%, can indicate hypoxemia, but addressing the lack of breathing takes precedence. Option C, eight premature ventricular beats every minute, and option D, a disconnected monitor signal, are important but do not pose an immediate threat to the client's life compared to respiratory apnea.
2. A client with a history of myocardial infarction is experiencing chest pain. Which intervention should the nurse implement first?
- A. Administer oxygen therapy as prescribed.
- B. Administer aspirin as prescribed.
- C. Administer nitroglycerin sublingually as prescribed.
- D. Obtain an electrocardiogram (ECG).
Correct answer: A
Rationale: Administering oxygen therapy is the initial priority in managing chest pain in a client with a history of myocardial infarction. Oxygen therapy helps improve oxygenation, which is crucial in reducing myocardial damage. While administering aspirin and nitroglycerin are essential interventions in the treatment of myocardial infarction, oxygen therapy takes precedence because it addresses the immediate need for oxygen supply to the heart muscle. Obtaining an ECG is important but can be done after ensuring adequate oxygenation.
3. The nurse is caring for a client with a chest tube following a pneumothorax. Which finding requires immediate intervention?
- A. Oxygen saturation of 94%
- B. Crepitus around the insertion site
- C. Subcutaneous emphysema
- D. Drainage of 50 ml per hour
Correct answer: C
Rationale: Subcutaneous emphysema is the most critical finding requiring immediate intervention in a client with a chest tube following a pneumothorax. It may indicate a pneumothorax recurrence or air leak, which can lead to respiratory compromise. Oxygen saturation of 94% is slightly low but may not require immediate intervention. Crepitus around the insertion site can be a normal finding post-procedure. Drainage of 50 ml per hour is within the expected range for a chest tube output and does not indicate an immediate concern.
4. A woman who takes pyridostigmine for myasthenia gravis (MG) arrives at the emergency department complaining of extreme muscle weakness. Her adult daughter tells the nurse that since yesterday her mother has been unable to smile. Which assessment finding warrants immediate intervention by the nurse?
- A. Uncontrollable drooling.
- B. Inability to raise voice.
- C. Tingling of extremities.
- D. Eyelid drooping.
Correct answer: A
Rationale: Uncontrollable drooling can be a sign of a myasthenic crisis, which requires immediate medical intervention to prevent respiratory failure. Drooling indicates difficulty in swallowing, which can lead to aspiration and respiratory compromise. Inability to raise voice (choice B) and tingling of extremities (choice C) are not typically associated with myasthenic crisis. Although eyelid drooping (choice D) is a common symptom of myasthenia gravis, it is not as urgent as uncontrollable drooling in indicating a potential crisis.
5. 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.
