Extract:
Question 1 of 5
A nurse is reviewing the serum laboratory findings for a client who has hypertension and is prescribed hydrochlorothiazide. Which of the following findings should the nurse report to the provider?
Correct Answer: B
Rationale: Potassium 2.3 mEq/L is significantly below the normal range (3.5-5.0 mEq/L), indicating hypokalemia, which can lead to arrhythmias and requires prompt reporting.
Question 2 of 5
A nurse is caring for a client in the emergency department (ED). The client presents with substernal chest pain that comes and goes. The client states that the pain has been occurring for the last 6 hours. The pain, at times, radiates down the left arm. The client also reports intermittent nausea. The client appears pale and slightly diaphoretic. The client rates current pain as 8 on a scale of 0 to 10. The nurse is planning care for the client. For each potential prescription, indicate whether it is indicated, nonessential, or contraindicated.
| Options | Indicated | Nonessential | Contraindicated |
|---|---|---|---|
| Administering oxygen to maintain oxygen saturation >94%. | |||
| Intubation. | |||
| Continuous ECG monitoring. | |||
| Obtain the client's family history of cardiovascular disease. |
Correct Answer: A,C
Rationale: Administering oxygen to maintain oxygen saturation >94% is indicated to prevent myocardial hypoxia in suspected acute coronary syndrome. Continuous ECG monitoring is essential to detect arrhythmias, ischemia, and ST changes.
Question 3 of 5
A nurse is performing an ECG on a client who is experiencing chest pain. Which of the following statements should the nurse make?
Correct Answer: B
Rationale: Electrodes applied to the chest and extremities detect the electrical activity of the heart, necessary for accurate ECG readings and diagnosing potential cardiac issues.
Question 4 of 5
A nurse is teaching a newly licensed nurse about evaluating a cardiac rhythm. Which of the following options should the nurse identify as the P wave in the ECG complex?
Correct Answer: A
Rationale: The first upward deflection in an ECG represents the P wave, indicating atrial depolarization. It precedes the QRS complex and corresponds to the electrical activity associated with atrial contraction, initiating the cardiac cycle.
Question 5 of 5
A nurse is teaching a client who has hypertension and a new prescription for atenolol. Which of the following findings should the nurse include as adverse effects of this medication?
Correct Answer: D
Rationale: Bradycardia, a decrease in heart rate, is a known adverse effect of atenolol as it reduces sympathetic nervous system activity.
