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

Answer and Explanation

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. By directly relaxing vascular smooth muscle is not how lisinopril primarily works; it does not act directly on smooth muscle but rather affects hormonal pathways.

B. By blocking aldosterone from binding to mineralocorticoid receptors is a secondary effect of the angiotensin-converting enzyme (ACE) inhibitors but not the primary action of lisinopril itself.

C. By blocking the movement of calcium ions into arterial smooth muscles describes the action of calcium channel blockers, not ACE inhibitors like lisinopril.

D. By inhibiting the transformation of angiotensin I to angiotensin II is the correct answer because lisinopril inhibits the ACE enzyme, reducing the production of angiotensin II, which lowers blood pressure and decreases strain on the heart.

A. "This insulin peaks in 6-12 hours." B. "I will take this insulin before breakfast." C. "This insulin lasts for 12-18 hours." D. "I will take this insulin right before eating meals to cover my carbohydrate intake."

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.
