The nurse on the medical-surgical unit is reviewing discharge instructions with a client who has a history of glaucoma. The nurse should anticipate the use of what medications?
Oral Cholinergics
Loop diuretics
Potassium-sparing diuretics
Antibiotics
The Correct Answer is A
A. Oral Cholinergics: Cholinergic medications, such as pilocarpine, help reduce intraocular pressure by increasing the outflow of aqueous humor. They are commonly used in the treatment of glaucoma to protect against optic nerve damage and preserve vision.
B. Loop diuretics: Loop diuretics like furosemide are used to manage fluid overload in conditions like heart failure or hypertension, not glaucoma. They do not influence intraocular pressure or aqueous humor dynamics.
C. Potassium-sparing diuretics: Potassium-sparing diuretics affect renal excretion of electrolytes and fluids, not intraocular pressure. They have no direct role in glaucoma treatment and are not prescribed for this condition.
D. Antibiotics: Antibiotics are prescribed to treat or prevent infection, particularly in conjunctivitis or post-surgical eye care. They are not used to manage chronic conditions like glaucoma unless there is a concurrent infection.

Correct Answer is A
Explanation
A. Increase fluid intake: Increasing fluid intake helps restore cerebrospinal fluid volume that may have been lost during the lumbar puncture, which often causes post-lumbar puncture headaches. Hydration supports healing of the puncture site and can reduce the intensity and duration of the headache.
B. Administer pain medication: Pain medication can provide symptomatic relief but does not address the underlying cause of the headache, which is cerebrospinal fluid leakage and decreased pressure. While useful, it is not the primary intervention to facilitate resolution.
C. Darken the client's room and close the door: This action can help reduce sensory stimuli and provide comfort during a headache but does not directly treat the cause of a post-lumbar puncture headache. It is an adjunct comfort measure rather than a primary treatment.
D. Elevate the head of the bed to 30 degrees: Elevating the head may actually worsen a post-lumbar puncture headache by promoting further cerebrospinal fluid leakage. Typically, keeping the client flat or slightly elevated is recommended to reduce symptoms.
Correct Answer is B
Explanation
A. "I have intense pain above my eyebrow.": Pain above the eyebrow may indicate conditions like sinusitis or angle-closure glaucoma, but retinal detachment typically presents without pain. Its symptoms are visual rather than sensory.
B. "It looked like a curtain was closing and I can only see bright flashes of light.": A sudden curtain-like shadow and flashes of light (photopsia) are classic signs of retinal detachment. These occur due to the retina pulling away from the back of the eye, disrupting vision.
C. "My vision has a cloudy appearance.": Cloudy vision is more commonly associated with cataracts or corneal issues. Retinal detachment usually presents with more acute and dramatic vision changes like darkening or loss of visual fields.
D. "I'm having trouble with my peripheral vision.": Peripheral vision loss can occur in retinal detachment but tends to follow the more distinctive symptoms like flashes and a curtain-like shadow. While relevant, it’s not diagnostically specific.
