A client diagnosed with primary open-angle glaucoma received a prescription for miotic eye drops. Which instruction should the nurse plan to include in this client's teaching?

"Wash your hands after each administration of eye drops."

"Squeeze your eye closed after administering the drops."

"Do not allow the dropper bottle to touch the eye."

"Administer the medication directly on the cornea."

Answer and Explanation

The Correct Answer is C

A. "Wash your hands after each administration of eye drops" is important but not specific to the safe administration of miotic eye drops. Washing hands before administration is more relevant to preventing infection.

B. "Squeeze your eye closed after administering the drops" can force the medication out of the eye, reducing its effectiveness. Instead, the client should be instructed to close the eye gently and apply pressure to the inner canthus to prevent systemic absorption.

C. "Do not allow the dropper bottle to touch the eye" is correct because it prevents contamination of the dropper, which could lead to eye infections.

D. "Administer the medication directly on the cornea" is incorrect because eye drops should be placed in the conjunctival sac, not directly on the cornea, to minimize irritation and maximize absorption.

Correct Answer is B

Explanation

A. Compare muscle strength bilaterally is not the most immediate concern. Although muscle weakness is a potential sign of hypokalemia, the priority is assessing for cardiac complications, as potassium imbalances can cause life-threatening arrhythmias.

B. Determine apical heart rate and rhythm is the most important intervention. A potassium level of 2.5 mEq/L is dangerously low and can lead to life-threatening cardiac arrhythmias. The nurse should assess the heart rate and rhythm to detect any abnormalities such as bradycardia, tachycardia, or irregular rhythms, which are common in hypokalemia.

C. Observe color and amount of urine is not the priority. While renal function is important, the immediate concern in this case is the potential for severe cardiac complications due to the low potassium level.

D. Assess strength of deep tendon reflexes is important for detecting signs of hypokalemia, but it is secondary to assessing the heart, as potassium imbalances primarily affect cardiac function.

A. A private room with both contact and airborne precautions. B. A semiprivate room with a roommate who has the same diagnosis and airborne precautions. C. A private room with both standard and droplet precautions. D. A semiprivate room with a roommate who has the same diagnosis and contact precautions.

Correct Answer is A

Explanation

A. A private room with both contact and airborne precautions is appropriate for a client with varicella zoster virus (chickenpox or shingles in an immunocompromised state). This virus can spread through direct contact with lesions and airborne transmission of respiratory droplets.

B. A semiprivate room with a roommate who has the same diagnosis and airborne precautions could be considered if the roommate also has the same strain of the virus, but a private room is generally preferred to minimize cross-contamination risks.

C. A private room with both standard and droplet precautions is insufficient. Airborne precautions are necessary because varicella zoster virus can spread via airborne routes.

D. A semiprivate room with a roommate who has the same diagnosis and contact precautions does not account for the airborne transmission risk, making this option inappropriate.
