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 ["0.6"]
Explanation
Step 1: The medication is prescribed as 30 mg every 12 hours, which means it is given twice a day. So, the total daily dosage in mg is 30 mg × 2 = 60 mg.
Step 2: The medication is available in 30 mg per 0.3 mL. So, to find out how many mL correspond to 60 mg, we set up a proportion: (30 mg / 0.3 mL) = (60 mg / x mL). Solving for x gives x = (0.3 mL / 30 mg) × 60 mg = 0.6 mL.
Therefore, the practical nurse should administer 0.6 mL of the medication each day.
Correct Answer is A
Explanation
Circumoral cyanosis is a bluish discoloration around the mouth that indicates inadequate oxygenation. It is an abnormal finding in a full-term newborn and requires immediate assessment and intervention by the PN.
The other options are not correct because:
B. A positive Babinski's reflex is a normal finding in newborns that indicates intact neurological function. It is elicited by stroking the sole of the foot and observing the fanning of the toes.
C. A negative Ortolani's sign is a normal finding in newborns that indicates no hip dislocation or dysplasia. It is elicited by abducting the hips and feeling for any clicking or clunking sensation.
D. A large sacral "stork bite" is a common benign birthmark that appears as a reddish patch on the lower back or nape of the neck. It usually fades within the first year of life and does not require any treatment.
