A nurse is monitoring a client who is on telemetry. Which of the following findings on the ECG strip should the nurse recognize as normal sinus rhythm?

The T wave is in the inverted position.

The P wave falls before the QRS complex.

The QRS duration is 0.20 seconds.

The P-R interval measures 0.22 seconds.

Answer and Explanation

The Correct Answer is B

A. The T wave in the inverted position can indicate ischemia or electrolyte imbalances but does not define normal sinus rhythm.
B. The P wave falling before the QRS complex is characteristic of normal sinus rhythm.
C. A QRS duration of 0.20 seconds is within the normal range and does not specifically define normal sinus rhythm.
D. The P-R interval typically ranges from 0.12 to 0.20 seconds, and a slightly prolonged interval here wouldn't necessarily exclude normal sinus rhythm.

Correct Answer is ["5"]

Explanation

To calculate the infusion time for a 1-L bag of 0.9% sodium chloride at a rate of 200 mL/hr, you would divide the total volume of the IV bag by the hourly infusion rate. Since there are 1000 mL in a 1-L bag, you would calculate 1000 mL divided by 200 mL/hr, which equals 5 hours.

A. Propranolol B. Pantoprazole C. Lovastatin D. Morphine

Correct Answer is A

Explanation

A. Propranolol is a beta-blocker used to control blood pressure and heart rate. However, the nurse has a hold order for propranolol if the apical pulse (heart rate) is less than 50 beats per minute. The nurse documented a heart rate of 42 bpm at 0815, which falls below the hold parameter for propranolol. Administering propranolol in this case could worsen the client's bradycardia (slow heart rate) and therefore requires an incident report.
B. Pantoprazole is a proton pump inhibitor and doesn't have a direct impact on heart rate within the usual therapeutic range.
C. Lovastatin is a cholesterol medication and wouldn't cause a significant drop in heart rate at this dosage.
D. While morphine can slow the heart rate, it's typically used for pain management and may be necessary for the client's comfort. However, the nurse should monitor the respiratory rate closely due to potential respiratory depression.
E. Cefuroxime is an antibiotic and wouldn't significantly affect heart rate.
