A client has a new prescription for zolpidem, a hypnotic. The client tells the home health nurse that he plans to take a dose of the medication during the day because he is exhausted and needs to take a short afternoon nap prior to an evening activity in his home. Which action should the nurse take?

Encourage the client to wait until bedtime to take the medication.

Remind the client to drink plenty of fluids when taking the medication.

Advise the client to take the medication with the noon meal.

Explain that the client needs to allow for sleep time of at least two hours.

Answer and Explanation

The Correct Answer is A

Choice A reason: Zolpidem is a hypnotic drug that induces sleep by enhancing the activity of gamma-aminobutyric acid (GABA), a neurotransmitter that inhibits brain activity. Zolpidem is used to treat insomnia, or difficulty falling asleep or staying asleep. Zolpidem should be taken only at bedtime, when the client is ready to go to sleep and can devote at least seven to eight hours for uninterrupted sleep. Taking zolpidem during the day can cause excessive sedation, drowsiness, confusion, memory loss, and impaired coordination. Therefore, the nurse should encourage the client to wait until bedtime to take the medication and avoid daytime naps.

Choice B reason: Reminding the client to drink plenty of fluids when taking the medication is not an action that the nurse should take in this situation, but rather a general recommendation that applies to most medications. Drinking fluids can help to prevent dehydration, flush out toxins, and maintain kidney function. However, drinking fluids is not specific to zolpidem and does not affect its absorption or metabolism.

Choice C reason: Advising the client to take the medication with the noon meal is not an action that the nurse should take in this situation, but rather a harmful suggestion that can reduce the effectiveness of zolpidem and increase its side effects. Taking zolpidem with food can delay its onset of action and make it less potent. Taking zolpidem at noon can also interfere with the client's circadian rhythm, or natural sleep-wake cycle, and cause daytime sleepiness and nighttime insomnia.

Choice D reason: Explaining that the client needs to allow for sleep time of at least two hours is not an action that the nurse should take in this situation, but rather an inaccurate and insufficient information that can mislead the client and endanger their safety. Zolpidem has a half-life of about two hours, which means that half of its dose is eliminated from the body in two hours. However, this does not mean that its effects wear off in two hours. Zolpidem can still cause residual sedation and impairment for several hours after taking it. The client needs to allow for sleep time of at least seven to eight hours when taking zolpidem, not just two hours.

Correct Answer is C

Explanation

Choice A reason: Replacing leafy vegetables with a protein source is not necessary or advisable for a vegetarian client who takes warfarin. Leafy vegetables are rich in vitamin K, which can interfere with warfarin's anticoagulant effect, but they also provide other nutrients and benefits for health. Protein sources such as nuts or beans may also contain vitamin K or other substances that can affect warfarin's action.

Choice B reason: Commending the client for her healthy lifestyle and encouraging her to continue her current diet habits is not appropriate or safe for a vegetarian client who takes warfarin. Leafy vegetables can alter warfarin's anticoagulant effect and increase the risk of bleeding or clotting complications if not monitored closely by the healthcare provider.

Choice C reason: Advising the client that the healthcare provider needs to be made aware of her current diet is the best response for a vegetarian client who takes warfarin. Leafy vegetables can affect warfarin's anticoagulant effect by increasing vitamin K levels in the body, which counteracts warfarin's action. The healthcare provider can adjust the warfarin dose accordingly and monitor the client's international normalized ratio (INR), which is a measure of blood clotting time.

Choice D reason: Confirming that her diet choices will help the medication be more effective in preventing blood clots is incorrect and misleading for a vegetarian client who takes warfarin. Leafy vegetables can decrease warfarin's anticoagulant effect by increasing vitamin K levels in the body, which enhances blood clotting. This can reduce the effectiveness of warfarin and increase the risk of thromboembolic events, such as stroke or pulmonary embolism.

Correct Answer is ["0.1"]

Explanation

To find out how many mL of dalteparin are needed for 2500 units, we need to use a proportion formula:

- (units of dalteparin)/(mL of dalteparin) = (units of dalteparin prescribed)/(mL of dalteparin needed)

- We can plug in the values that we know into the formula:

- (5000 units)/(0.2 mL) = (2500 units)/(x mL)

- We can cross-multiply and solve for x:

- 5000x = 2500 x 0.2

- x = (2500 x 0.2)/5000

- x = 0.1

- Therefore, the nurse should administer 0.1 mL of dalteparin to deliver 2500 units of the medication.
