The nurse provides a client with a dose of the beta-selective adrenergic agonist isoproterenol. Which assessment finding indicates the medication is effective?
Constricted pupils
Warm, dry skin
Increased heart rate
Decreased urine output
The Correct Answer is C
A. Constricted pupils are not an expected response to isoproterenol, which generally causes dilation of the pupils due to sympathetic stimulation.
B. Warm, dry skin is not a direct indicator of the effectiveness of isoproterenol; it could result from various factors unrelated to the medication's action.
C. Increased heart rate indicates that isoproterenol, which is a beta-agonist, is effectively stimulating the beta-adrenergic receptors, leading to increased cardiac output and heart rate.
D. Decreased urine output is not a sign of effectiveness and could indicate adverse effects such as reduced renal perfusion.

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 A
Explanation
A. A return to normal respiratory rate, rhythm, and depth is correct because opioid antagonists, such as naloxone, are primarily used to reverse the respiratory depression caused by opioid overdose.
B. Management of alcohol withdrawal symptoms is incorrect; opioid antagonists do not address alcohol withdrawal.
C. A reduction in the client's rating of their pain is incorrect; opioid antagonists counteract the effects of opioids, which can result in increased pain levels rather than reduction.
D. Alertness and improve memory function is incorrect; while opioid antagonists may improve alertness by reversing sedation, the primary goal focuses on restoring respiratory function.
