A patient has been newly prescribed gentamicin 120mg, IM, once.

After reviewing the patient’s home medication list, which medication should the nurse be most concerned about?

Choice A rationale
A persistent cough is not directly related to the administration of famotidine. Famotidine is a histamine-2 blocker that works by decreasing the amount of acid the stomach produces. It is used to treat and prevent ulcers in the stomach and intestines and to treat conditions in which the stomach produces too much acid. A persistent cough could be a symptom of many other conditions, but it is not a direct indicator of the effectiveness or ineffectiveness of famotidine.
Choice B rationale
The absence of a sour taste in the mouth, often associated with acid reflux, could suggest that famotidine is working as it should. However, the absence of a sour taste does not definitively indicate that the medication has had its intended effect, as the patient may not have experienced this symptom even before taking the medication.
Choice C rationale
Famotidine is used to decrease the amount of acid in the stomach. A normal stomach pH is typically around 1.5 to 3.5, which is highly acidic. If a patient’s stomach pH is measured at 5, which is less acidic than normal, it could suggest that the famotidine has not had its intended effect of reducing stomach acid.
Choice D rationale
While headaches are listed as a common side effect of famotidine, the presence of headaches does not necessarily suggest that the medication has not had its intended effect. Headaches could be caused by a variety of factors and are not a direct indicator of the level of stomach acid or the effectiveness of famotidine.

Choice A rationale
While aromatherapy sprays can provide a calming environment, there is limited evidence to suggest that they can effectively reduce chemotherapy-induced nausea and vomiting.
Choice B rationale
Physical activity like a brisk walk outside can be beneficial for overall health, but it may not directly help in reducing nausea and vomiting caused by chemotherapy.
Choice C rationale
Avoiding well-seasoned, spicy, and fatty foods can help reduce nausea and vomiting during chemotherapy. These types of foods can irritate the stomach and make nausea worse.
Choice D rationale
Drinking a warm glass of milk may not be helpful in reducing chemotherapy-induced nausea and vomiting. In fact, dairy products can sometimes exacerbate nausea.
