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 D
Explanation
A. The patient’s statement about the peak of NPH insulin being 6-12 hours is correct; it is important to know when to monitor for hypoglycemia.
B. Taking NPH before breakfast is appropriate, as it is typically given in the morning to provide coverage for meals throughout the day.
C. The duration of NPH insulin lasting for 12-18 hours is accurate, which is crucial for understanding how long the patient can expect blood glucose control.
D. NPH insulin should not be taken right before meals as it does not act quickly enough to cover immediate carbohydrate intake. Rapid-acting insulin is typically used for that purpose, indicating a need for further teaching.

A. Nitroglycerin is contraindicated with erectile dysfunction medications such as sildenafil (Viagra) because both can cause significant drops in blood pressure when used together, potentially leading to severe cardiovascular complications.
B. Furosemide is a diuretic and does not have a direct contraindication with erectile dysfunction medications, although it may contribute to electrolyte imbalances.
C. Verapamil is a calcium channel blocker that does not directly contraindicate the use of erectile dysfunction medications but should be monitored for potential interactions affecting heart rate and blood pressure.
D. Acetaminophen is a pain reliever and does not pose a contraindication for erectile dysfunction medications.
