To decrease intraocular pressure following cataract surgery, the nurse should instruct the client to avoid:

Deep breathing.

Ambulation.

Coughing.

Lying supine.

Answer and Explanation

The Correct Answer is C

Choice A rationale

Deep breathing doesn't significantly affect intraocular pressure. Techniques enhancing oxygen exchange are safe and recommended for general well-being during postoperative recovery periods.

Choice B rationale

Ambulation promotes circulation and is generally safe after surgery. Avoiding ambulation is unnecessary for maintaining intraocular pressure levels unless medically contraindicated.

Choice C rationale

Coughing increases intraocular pressure due to abrupt pressure changes within the chest cavity and ocular system. This should be avoided to prevent complications after cataract surgery.

Choice D rationale

Lying supine does not inherently increase intraocular pressure unless other factors like improper postoperative positioning are involved. Proper positioning is important but lying supine itself isn't contraindicated.

Correct Answer is B

Explanation

Choice A rationale

Fluid intake does not directly impact intraocular pressure. Management of glaucoma focuses on medications like eye drops and surgical interventions rather than restricting fluid intake.

Choice B rationale

Glaucoma treatments, including eye drops, aim to manage intraocular pressure. These medications are required lifelong to prevent optic nerve damage and preserve vision.

Choice C rationale

Excess salt impacts systemic blood pressure but does not directly influence intraocular pressure. Glaucoma management targets ocular pressure, not dietary sodium reduction.

Choice D rationale

Avoiding eye overuse may reduce strain but does not address intraocular pressure. Effective glaucoma treatment relies on pharmacological or surgical measures rather than activity limitation.

Correct Answer is ["2525"]

Explanation

Step 1 is calculate intake from lactated Ringer’s: 150 mL/hr × 9 hrs = 1350 mL.

Step 2 is calculate cefazolin intake: 100 mL × 1 dose = 100 mL.

Step 3 is calculate intake from two units of packed RBCs: 275 mL + 250 mL = 525 mL.

Step 4 is calculate intake from two IV boluses: 250 mL × 2 = 500 mL.

Step 5 is calculate intake from ranitidine infusion: 50 mL × 1 dose = 50 mL.

Step 6 is calculate total intake: 1350 mL + 100 mL + 525 mL + 500 mL + 50 mL = 2525 mL. Final calculated intake is 2525 mL.
