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.
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.

B. Providing access to a video about diabetes may be part of the teaching plan but should come after assessing the client's baseline knowledge.
C. Establishing short-term, realistic goals is important but should follow the assessment of the client's current knowledge and understanding.

Correct Answer is ["0.5"]
Explanation
To administer the correct dose of lorazepam, which is 1 mg, when only 2 mg tablets are available, the nurse should administer half a tablet. This is because each tablet contains 2 mg of lorazepam, and the prescribed dose is 1 mg. Therefore, dividing the tablet into two equal parts will provide the necessary 1 mg dose. The answer, rounded to the nearest tenth as per the instruction, is 0.5.
