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 B
Explanation
A. Rebound hypertension can occur if antihypertensive medications are abruptly stopped, but it is not a direct reason for switching from an ACE inhibitor to an angiotensin II receptor blocker.
B. A persistent cough is a well-known side effect of ACE inhibitors due to the accumulation of bradykinin. If the client experienced this side effect, it would likely prompt the healthcare provider to switch to an angiotensin II receptor blocker, which does not typically cause this issue.
C. A transient ischemic attack (TIA) would require urgent intervention but is not a reason for changing from an ACE inhibitor to an angiotensin II receptor blocker.
D. Non-adherence to ACE inhibitor treatment may lead to ineffective blood pressure control but would not directly justify a switch to a different class of medication.
Correct Answer is B
Explanation
A. Prothrombin time (PT) is used to monitor warfarin therapy, not heparin therapy.
B. Activated partial thromboplastin time (aPTT) is the primary laboratory test used to assess the effectiveness of heparin therapy, measuring the time it takes for blood to clot and ensuring therapeutic levels.
C. The International normalized ratio (INR) is also related to warfarin therapy rather than heparin.
D. Serum potassium level is not relevant for assessing heparin therapy but may be monitored for other reasons.
