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","C","D"]
Explanation
A. Sit up comfortably in the bed is incorrect; the client should be in an upright position, which can be done while sitting up comfortably, but it’s essential to emphasize a more upright posture for optimal administration.
B. Tilt the head slightly to the side is correct; this position helps facilitate the delivery of the medication into the nasal passages.
C. Insert the tip of the nose piece into one nostril is correct; proper insertion ensures effective delivery of the medication.
D. Hold the breath for a few seconds after administering the spray is correct; this allows the medication to be absorbed more effectively.
E. Blow the nose 1 minute after administering the spray is incorrect; clients should avoid blowing their nose immediately after use to allow for proper absorption of the medication.
