A nurse is caring for a client who started taking amitriptyline 6 days ago.
The client reports that the medication is not helping.
Which of the following responses should the nurse make?
"I will inform your provider so she can prescribe a different medication.”
"You will need to take this medication on an empty stomach for it to be more effective.”
"You will need to wait a couple of weeks to feel the therapeutic effect of the medication.”
"I will ask your provider to increase the dose of the medication.”
The Correct Answer is C
Choice A rationale:
While it’s important for the provider to be informed if the medication isn’t working, it’s premature to change the medication after only 6 days.
Choice B rationale:
Amitriptyline does not need to be taken on an empty stomach to be effective.
Choice C rationale:
Amitriptyline, a tricyclic antidepressant, often takes several weeks before a therapeutic effect is felt.
Choice D rationale:
Increasing the dose prematurely can lead to unnecessary side effects. It’s better to wait for the medication to take effect.

Correct Answer is D
Explanation
Choice A rationale:
Two loose stools in the past 24 hours could be a symptom of Clostridioides difficile infection, but it’s not necessarily a priority finding. The infection can cause diarrhea, but it’s not life-threatening.
Choice B rationale:
A WBC count of 11,000/mm³ is slightly elevated, indicating a possible infection. However, it’s not necessarily a priority finding as it’s not significantly high.
Choice C rationale:
A heart rate of 104/min is slightly elevated, indicating possible stress or anxiety. However, it’s not necessarily a priority finding as it’s not significantly high.
Choice D rationale:
Creatinine level of 3.1 mg/dL is significantly high, indicating possible kidney damage, which can be a side effect of vancomycin treatment. This should be reported to the provider immediately.
Correct Answer is C
Explanation
Choice A rationale:
Dry mouth is a common side effect of diphenhydramine. Diphenhydramine is an antihistamine that is often used to treat allergies, insomnia, and symptoms of the common cold. It works by blocking the effects of histamine, a substance in the body that causes allergy symptoms. One of the effects of histamine is increased salivation, so when diphenhydramine blocks this effect, it can lead to dry mouth.
Choice B rationale:
Nausea is also a common side effect of diphenhydramine. This can occur because diphenhydramine can slow down the emptying of the stomach, leading to feelings of nausea. Additionally, diphenhydramine can affect the vestibular system in the inner ear, which can also lead to feelings of nausea.
Choice C rationale:
Agitation is considered an idiosyncratic reaction to diphenhydramine. An idiosyncratic reaction is an unusual or unexpected reaction to a drug that is not related to the usual pharmacological action of the drug. While diphenhydramine is typically used for its sedative effects, in some cases it can cause paradoxical central nervous system stimulation, leading to agitation.
Choice D rationale:
Dizziness is another common side effect of diphenhydramine. This occurs because diphenhydramine can affect the vestibular system in the inner ear, which plays a key role in maintaining balance. When this system is affected, it can lead to feelings of dizziness.
