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?

Choice A rationale

Monitoring frequency of urination indicates bladder involvement, often related to cystitis. However, it does not indicate ascending progression to the kidneys, which is more severe and requires additional symptoms.

Choice B rationale

Dysuria, or painful urination, typically signifies lower urinary tract infection rather than progression to upper urinary tract infection, such as pyelonephritis. It is not specific to kidney involvement.

Choice C rationale

Flank pain and fever are hallmark symptoms of pyelonephritis, indicating ascending progression of infection from the bladder to the kidneys. These symptoms signal systemic involvement and require immediate medical attention.

Choice D rationale

Pyuria and hematuria are signs of bladder infection but do not indicate progression to kidney infection. These are specific to inflammation or infection in the lower urinary tract.

Choice A rationale

The frontal lobe controls executive functions like reasoning and planning, not object identification errors. Damage here leads to issues with decision-making and voluntary movement, not misidentification of objects.

Choice B rationale

The temporal lobe processes auditory information and object recognition. Injury disrupts the brain's ability to associate visual stimuli with correct labels, causing errors like calling a pen "a key.”.

Choice C rationale

The parietal lobe processes sensory information related to touch, pain, and spatial awareness. Damage causes difficulty with spatial relations and perception but doesn't typically involve visual misidentification.

Choice D rationale

The occipital lobe handles visual processing. Damage affects vision or visual interpretation but does not impair the recognition or labeling of objects directly.
