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. Performing a blood sugar analysis is important, but the immediate symptoms indicate hypoglycemia, and rapid treatment is necessary before confirming blood sugar levels.
B. Having the client drink a glass of orange juice provides a quick source of glucose to counteract hypoglycemia, which is the most appropriate initial response to address the client's symptoms.
C. Administering 1 ampule of 50% dextrose intravenously is an appropriate intervention for severe hypoglycemia but is not the initial step for a client who can still take oral carbohydrates.
D. Administering insulin would worsen the client's condition by lowering blood sugar levels further, which is not indicated in this scenario.
Correct Answer is C
Explanation
A. An increased risk for CNS depression is not typically associated with opioid agonist-antagonists; instead, these medications may produce a ceiling effect on sedation compared to full agonists.
B. Respiratory depression is more commonly associated with full opioid agonists rather than agonist-antagonists. Agonist-antagonists can sometimes counteract respiratory depression caused by full agonists.
C. Opioid withdrawal symptoms can occur when a client who is dependent on full agonist opioids is given an agonist-antagonist, as these medications can displace the agonist from receptors, leading to withdrawal.
D. Hypotension is a possible side effect of opioids but is not a specific concern with the use of agonist-antagonists in the context of opioid therapy.
