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. "I will take this medication at bedtime to help with my symptoms." is correct; famotidine is often taken at bedtime to reduce nocturnal gastric acid secretion and help manage symptoms.
B. "I can take this medication with antacids for faster relief." is incorrect; antacids can interfere with the absorption of famotidine, and patients should be advised to separate the doses by at least an hour.
C. "I should avoid alcohol while taking this medication." is correct; alcohol can increase the risk of gastrointestinal irritation and should generally be avoided.
D. "I will monitor for signs of unusual bleeding or bruising." is correct; while famotidine is not typically associated with bleeding risks, monitoring for signs of unusual bleeding is a good practice when taking any medication, particularly in patients with risk factors.
Correct Answer is B
Explanation
A. Administer the insulin to the client is incorrect as the nurse should first verify the dosage for safety before administration.
B. Check the dosage with another nurse is correct because double-checking the insulin dosage with another licensed nurse is a critical safety step to prevent medication errors.
C. Check the client's blood sugar again is incorrect; while monitoring blood sugar is important, it is not the immediate next action after preparing the insulin.
D. Ensure a meal tray is available is incorrect; although the client should have a meal ready after insulin administration, the priority action before administering the medication is to confirm the dosage.
