A nurse is teaching a client about a medication that has a receptor with an antagonist effect.
Which information should the nurse include in the teaching?
This medication will not change the effects of normal cellular functions.
This medication can block the usual receptor activity.
This medication will increase the effects of normal cellular functions.
This medication will increase and decrease the effects on normal cellular functions.
The Correct Answer is B
Choice A rationale
This statement is incorrect because an antagonist medication changes the effects of normal cellular functions by blocking receptors.
Choice B rationale
An antagonist medication binds to receptors and blocks the usual receptor activity, preventing the normal action of the endogenous substance.
Choice C rationale
This statement describes an agonist medication, which binds to receptors and increases the effects of normal cellular functions.
Choice D rationale
This statement is incorrect because an antagonist medication does not both increase and decrease the effects on normal cellular functions; it primarily blocks receptor activity.

Correct Answer is A
Explanation
Choice A rationale
Losartan is an angiotensin II receptor blocker (ARB) that helps lower blood pressure by relaxing blood vessels. It is often prescribed for clients who cannot tolerate angiotensin-converting enzyme (ACE) inhibitors like Captopril or Lisinopril due to side effects such as a persistent cough.
Choice B rationale
Digoxin is a medication primarily used to treat heart failure and atrial fibrillation. It is not typically prescribed for the management of hypertension as it does not directly lower blood pressure.
Choice C rationale
Captopril is an ACE inhibitor that can cause a persistent cough in some patients. Since the client has experienced this side effect, it is unlikely that Captopril would be prescribed again.
Choice D rationale
Lisinopril is another ACE inhibitor, similar to Captopril. Given the client's history of a cough caused by ACE inhibitors, Lisinopril is also not a suitable option.
Correct Answer is B
Explanation
Choice A rationale
While metformin is commonly used as a first-line medication for type 2 diabetes, this choice does not specifically address a critical safety concern related to metformin.
Choice B rationale
Metformin can interact with contrast dyes used in imaging studies, increasing the risk of acute renal failure due to lactic acidosis. Patients need to be aware of this interaction to avoid potential complications.
Choice C rationale
Metformin is used to lower blood glucose levels, not increase them. This choice is incorrect.
Choice D rationale
While metformin is associated with less weight gain compared to other diabetes medications, this choice does not address the critical interaction with contrast dye.
