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 ["200"]

Explanation

To calculate the infusion rate in mL/hr for administering clindamycin 900 mg in 100 mL dextrose 5% over 30 minutes, you would use the formula: (Total Volume in mL / Time in hours) = Rate in mL/hr. Since the medication needs to be administered over 30 minutes, you convert 30 minutes into hours, which is 0.5 hours. Using the formula, you get (100 mL / 0.5 hours) = 200 mL/hr. Therefore, the nurse should set the IV pump to deliver 200 mL/hr.
