The practical nurse (PN) is reviewing a client's recent ophthalmic screening test results. Findings of optic neuropathy, loss of peripheral vision, and increased intraocular pressure are consistent with which medical condition?
Glaucoma.
Macular edema.
Cataract.
Diabetic retinopathy.
The Correct Answer is A
Glaucoma is a group of eye diseases that damage the optic nerve and cause vision loss. It is often associated with increased intraocular pressure, which can compress the nerve fibers and reduce blood flow to the retina. The most common type of glaucoma, open-angle glaucoma, causes gradual loss of peripheral vision.
The other options are not correct because:
A. Macular edema is a condition that causes swelling and fluid accumulation in the macula, the central part of the retina that is responsible for sharp and detailed vision. It can cause blurred or distorted vision, but it does not affect the optic nerve or the peripheral vision.
B. Cataract is a condition that causes clouding of the lens, which is the transparent structure that focuses light onto the retina. It can cause blurred, dim, or yellowed vision, but it does not affect the optic nerve or the intraocular pressure.
C. Diabetic retinopathy is a complication of diabetes that damages the blood vessels in the retina and causes bleeding, leakage, or scarring. It can cause blurred, fluctuating, or darkened vision, but it does not affect the optic nerve or the intraocular pressure.

Correct Answer is B
Explanation
This is the best intervention for the PN to implement because it relieves the muscle spasm and reduces the pain of a leg cramp. Leg cramps are common during pregnancy and labor due to changes in calcium levels, fluid balance, or pressure on nerves and blood vessels.
A. Massaging the calf and foot is not recommended because it may increase pain or cause injury to the muscle or nerve.
C. Checking the pedal pulse in the affected leg is not necessary unless there is a suspicion of vascular compromise or thrombosis, which are unlikely causes of a leg cramp.
D. Elevating the leg above the heart is not helpful because it may impair blood flow or increase pressure on the nerve or muscle.
Correct Answer is B
Explanation
The correct answer is choice B. Attach the drainage bag to the bed frame.
Choice A rationale:
Measuring the urinary output in the bag is a routine task but does not address the improper placement of the drainage bag. The immediate concern is to ensure the drainage bag is correctly positioned to prevent complications.
Choice B rationale:
Attaching the drainage bag to the bed frame is the correct action. The drainage bag should be kept below the level of the bladder and attached to a non-movable part of the bed to prevent backflow and reduce the risk of infection.
Choice C rationale:
Applying gloves and emptying the drainage bag is not the immediate priority. The drainage bag should not be allowed to overfill, but in this scenario, it is only half-full, so this action is not urgent.
Choice D rationale:
Removing the looped tubing from the bed is important to ensure proper drainage and prevent backflow, but it does not address the incorrect placement of the drainage bag, which is the primary concern in this situation.
