A female client with multiple sclerosis reports having less fatigue and improved memory since she began using the herbal supplement, ginkgo biloba. Which information is most important for the nurse to include in the teaching plan for this client?

Choice A reason: Monitoring for signs of sodium and fluid retention is not relevant to this situation, as broad spectrum antibiotics do not affect sodium or fluid balance. Sodium and fluid retention may be caused by other conditions such as heart failure, kidney disease, or liver disease.

Choice B reason: Obtaining wound and blood specimens for culture and sensitivity is most important before administering the first dose of a broad spectrum antibiotic, as this can help identify the specific type and strain of bacteria causing the infection and determine which antibiotic is most effective against it. Broad spectrum antibiotics are effective against a wide range of bacteria, but they may also kill beneficial bacteria and increase the risk of resistance or superinfection.

Choice C reason: Obtaining a complete blood count and serum electrolytes is not necessary before administering the first dose of a broad spectrum antibiotic, as these tests do not provide information about the type or severity of infection. A complete blood count may show an elevated white blood cell count or other changes in response to infection, but it does not identify the causative organism. Serum electrolytes may show abnormalities due to dehydration, vomiting, diarrhea, or other factors, but they do not indicate infection.

Choice D reason: Performing irrigation and topical antibiotic application to wound area is not sufficient before administering the first dose of a broad spectrum antibiotic, as this may not reach all sites of infection or eradicate all bacteria. Irrigation and topical antibiotic application may help clean and prevent further contamination of wound area, but they do not replace systemic antibiotic therapy.

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.
