A nurse is preparing to administer diphenhydramine 35 mg IM to a client who has schizophrenia. Available is diphenhydramine for injection 50 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.7"]
To determine how many mL to administer, use the formula:
mL= Desired Dose/Available Dose per mL mL= 35mg/50 mg/mL
= 0.7 mL
Thus, the nurse should administer 0.7 mL of diphenhydramine.

Correct Answer is A
Explanation
A. Checking the patient's baseline blood pressure helps to determine if the current reading of 98/66 mm Hg is normal for them or if it represents a significant change.
B. This may not be necessary if the blood pressure is normal for the patient. Hypotension is relative, and what is considered low for one person might be normal for another.
C. While this is a good practice, it should be done after determining if there is a significant change from the baseline. The irregular pulse could be due to various factors, including medications, but the first step is to understand the patient's normal range.
D. The patient's pulse is 76 beats/min, which is not bradycardic (bradycardia is defined as a heart rate less than 60 beats/min). Therefore, notifying the doctor of bradycardia is not appropriate in this case.
