A nurse is caring for a patient with acne who has been prescribed tetracycline. The patient states that they drink a glass of milk every morning with breakfast. What is the nurse's best response?
"Milk helps the medication absorb more quickly."
"You should avoid milk and dairy products when taking tetracycline, as they reduce its effectiveness."
"It is safe to take milk with tetracycline, as long as you increase your water intake."
"It is fine to drink milk if taken at least 1 hour before or 2 hours after."
The Correct Answer is B
A. Milk does not enhance the absorption of tetracycline; rather, it contains calcium, which can bind to the antibiotic and reduce its absorption.
B. Avoiding milk and dairy products while taking tetracycline is essential as they reduce the medication's effectiveness by forming insoluble complexes with the drug.
C. Taking milk with tetracycline is not safe due to the risk of decreased absorption; simply increasing water intake does not negate this interaction.
D. While spacing the intake of milk and tetracycline might seem beneficial, it is best to avoid dairy entirely during the treatment to ensure maximum efficacy of the medication.

Correct Answer is C
Explanation
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.
