The nurse would contact the health care provider before administering an adrenergic drug to a client who is also taking which drug?
Antibiotic
MAO inhibitor
Diuretic
Analgesic
The Correct Answer is B
A. Antibiotics do not typically interact with adrenergic drugs in a way that would necessitate contacting the healthcare provider before administration.
B. MAO inhibitors can cause significant interactions with adrenergic drugs, potentially leading to hypertensive crises due to increased norepinephrine levels. Therefore, the nurse should contact the healthcare provider to assess the risks before administering an adrenergic agent.
C. Diuretics may affect fluid and electrolyte balance, but they do not pose a direct interaction risk with adrenergic drugs that would require prior consultation with the healthcare provider.
D. Analgesics do not have a significant interaction with adrenergic drugs that would warrant contacting the healthcare provider, as they are used for pain management and can often be safely administered together.

Correct Answer is C
Explanation
A. Metformin does not stimulate the pancreas to produce more insulin; that action is characteristic of sulfonylureas.
B. Metformin does not increase the absorption of glucose in the intestines; rather, it works by reducing the amount of glucose released into the bloodstream.
C. Metformin primarily decreases glucose production in the liver and improves insulin sensitivity in peripheral tissues, which helps lower blood sugar levels. This makes it effective for managing type 2 diabetes.
D. While metformin can have effects on fat metabolism, its primary action is not to decrease fat breakdown but to manage blood glucose levels.
Correct Answer is A
Explanation
A. "There can be an unsafe reaction between your antidepressant and St. John's wort, which is why taking them both is discouraged." is correct; St. John's wort can reduce the effectiveness of SSRIs and may increase the risk of serotonin syndrome, making it vital for the nurse to address this safety concern.
B. "Herbal remedies often contain unknown doses of the desired ingredient, which can be dangerous." is a valid point, but it does not specifically address the interaction with the client’s current medication.
C. "It's very important that you not take the St. John's wort at the same time of day as your antidepressant." is misleading; the concern is not just about timing but about taking both together at all.
D. "It's very important that you comply with your prescribed treatment." while true, this response does not directly address the specific risks associated with combining St. John's wort and citalopram.
