The client is being discharged from the ambulatory care unit following cataract removal.
The nurse provides instructions regarding home care.
Which of the following, if stated by the client, indicates an understanding of the instructions?
I will sleep on the operative side for two weeks.
I will not lift anything more than 30 pounds (13.6 kg).
I will wear an eye shield at night and glasses during the day.
I will avoid using eye drops for the first week.
The Correct Answer is C
Choice A rationale
Sleeping on the operative side increases pressure on the eye, risking complications like increased intraocular pressure and disrupted healing of surgical incisions. Postoperative care avoids this positioning.
Choice B rationale
Lifting items over 5-10 pounds risks increased intraocular pressure. Guidelines usually limit lifting to light objects, not 30 pounds. Heavy lifting can cause strain affecting surgical recovery.
Choice C rationale
Eye shields protect the operative site during sleep, preventing accidental trauma, while glasses shield from debris during daytime. These preventive measures support proper healing and recovery post-cataract surgery.
Choice D rationale
Avoiding eye drops disrupts healing as prescribed medications manage inflammation and prevent infections after surgery. Proper use of eye drops supports post-surgical recovery effectively.

Correct Answer is B
Explanation
Choice A rationale
Ventriculostomies are inserted directly through the skull into the ventricles, not via the femoral artery. This method provides direct access to cerebrospinal fluid for drainage and pressure monitoring.
Choice B rationale
Ventriculostomies are placed to monitor intracranial pressure and drain excess cerebrospinal fluid, managing conditions like hydrocephalus or elevated intracranial pressure following brain injury or surgery.
Choice C rationale
An EEG monitors electrical brain activity but is unrelated to ventriculostomy placement. Ventriculostomy focuses on fluid drainage and pressure management, not on electrical diagnostic procedures.
Choice D rationale
Ventriculostomies carry a significant risk of infection due to the invasive nature of the procedure. Proper aseptic technique is critical to minimizing, not eliminating, the risk of infection.
Correct Answer is A
Explanation
Choice A rationale
Cervical spinal cord injuries at or above C3 disrupt the phrenic nerve, impairing diaphragm control, leading to respiratory failure. Mechanical ventilation compensates for the loss of neural signals required for effective breathing.
Choice B rationale
Unconsciousness alone does not necessitate ventilation unless breathing is compromised. Here, respiratory failure stems from cervical nerve injury, not loss of consciousness, requiring mechanical support.
Choice C rationale
The lungs themselves are not damaged in cervical spinal cord injuries; the issue lies in disrupted nerve signals needed for diaphragm and respiratory muscle function, necessitating ventilatory assistance.
Choice D rationale
Smoking history does not explain the acute respiratory failure caused by cervical spinal cord injuries. The need for ventilation directly results from damage to the neural control of respiratory muscles.
