A nurse is preparing to administer morphine 7.5 mg subcutaneous. Available is morphine injection 10 mg/mL. How many mL should the nurse administer?
(Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["0.75"]

To calculate the volume of morphine injection that the nurse should administer, we can use the following steps:

Determine the volume to be administered:

We have a concentration of 10 mg/mL.

7.5 mg ÷ 10 mg/mL = 0.75 mL

Therefore, the nurse should administer 0.75 mL of morphine injection subcutaneously.

A. Immediately report a dry cough B. Low heart rate is common with this medication C. Do not take this medication with birth control D. Do not get up without assistance

Correct Answer is D

Explanation

Choice A reason: This is incorrect because a dry cough is not a common or serious side effect of hydralazine. A dry cough is more likely to occur with angiotensin-converting enzyme (ACE) inhibitors, which are another class of antihypertensive drugs.

Choice B reason: This is incorrect because hydralazine does not cause a low heart rate. In fact, hydralazine can cause a reflex increase in heart rate as a result of lowering the blood pressure. This is why hydralazine is often given with a beta-blocker, which can slow down the heart rate.

Choice C reason: This is incorrect because hydralazine does not interact with birth control. However, the nurse should advise the client to use effective contraception while taking hydralazine, as this medication can cause fetal harm if used during pregnancy.

Choice D reason: This is correct because hydralazine can cause orthostatic hypotension, which is a sudden drop in blood pressure when changing positions. This can lead to dizziness, fainting, and falls. The nurse should instruct the client to avoid getting up too quickly and to ask for assistance if needed.
