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

Administering oxygen at 6 liters per minute via nasal cannula risks hypercapnia in a client with emphysema due to impaired CO2 elimination. Oxygen should be titrated to maintain safe saturation levels, usually 88–92%.

Choice B rationale

Ipratropium is a bronchodilator that safely alleviates airway constriction in emphysema without systemic cardiovascular effects, making it suitable for a client with coronary artery disease and chronic obstructive pulmonary conditions.

Choice C rationale

Propranolol is contraindicated in emphysema due to its beta-blocking effects, which may exacerbate bronchoconstriction and reduce respiratory function, posing a significant risk to the client’s health.

Choice D rationale

Organic herbal supplements lack evidence-based safety and efficacy, especially in complex medical conditions like coronary artery disease and emphysema. They can also interact adversely with prescribed medications.

A. Obtain a blood specimen to check for serum drug levels. B. Administer lorazepam IV to stop the convulsive activity. C. Check the client's blood pressure and heart rate.

Correct Answer is B

Explanation

Choice A rationale

Checking serum drug levels provides insight into compliance and effectiveness but doesn’t address immediate seizure cessation, prioritizing treatment over diagnostic assessment.

Choice B rationale

Administering lorazepam IV halts seizure activity quickly by enhancing GABA activity, calming neuronal excitation, and stabilizing the patient’s condition, reducing potential complications.

Choice C rationale

Monitoring vitals like blood pressure and heart rate is essential but doesn’t directly address convulsive activity, which requires immediate pharmacological intervention to prevent status epilepticus progression. .
