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 A
Explanation
A. Phenylephrine is a decongestant that can raise blood pressure, making it contraindicated for individuals with hypertension. Advising a patient with hypertension to avoid phenylephrine is essential to prevent potential cardiovascular complications.
B. While patients with diabetes should be cautious about certain medications, phenylephrine is not specifically contraindicated in this condition.
C. A 17-year-old female with an upper respiratory infection typically does not have contraindications for phenylephrine unless there are underlying conditions not mentioned.
D. Gout does not have a direct contraindication for phenylephrine use, so the patient may not need to avoid it unless other health issues are present.
