The practical nurse (PN) is reviewing a client's recent ophthalmic screening test results. Findings of optic neuropathy, loss of peripheral vision, and increased intraocular pressure are consistent with which medical condition?

The correct answer is choiceB. Culture for sensitive organisms.

Choice A rationale:

C-reactive protein (CRP) levels are indicative of inflammation in the body and can help identify the presence of an infection. However, CRP levels do not provide specific information about the type of organism causing the infection, which is crucial for targeted treatment.

Choice B rationale:

A culture for sensitive organisms is essential in this scenario because it identifies the specific bacteria or other pathogens present in the wound. This information is critical for selecting the appropriate antibiotic therapy to treat the infection effectively.

Choice C rationale:

Serum albumin levels are important for assessing nutritional status and overall health, which can impact wound healing. Low albumin levels can indicate poor nutritional status and delayed wound healing, but they do not provide immediate information about the infection itself.

Choice D rationale:

Serum blood glucose (BG) levels are crucial for managing diabetes and can affect wound healing. High blood glucose levels can impair the immune response and slow down the healing process. However, like CRP, BG levels do not provide specific information about the type of infection present in the wound.

The correct answer is choiceB. Remove the warm compress.

Choice A rationale:

Turning the lights on in the room would likely exacerbate the resident’s photophobia (sensitivity to light), causing more discomfort.Photophobia is a common symptom of bacterial conjunctivitis, and keeping the room dim can help alleviate this discomfort.

Choice B rationale:

Removing the warm compress is the correct action. Warm compresses can sometimes be used to relieve symptoms of conjunctivitis, but they are generally more appropriate for viral or allergic conjunctivitis.In the case of bacterial conjunctivitis, warm compresses can potentially worsen the infection by providing a warm, moist environment that promotes bacterial growth.Instead, a cool compress is often recommended to reduce inflammation and discomfort.

Choice C rationale:

Elevating the head of the bed can help reduce swelling and promote drainage, but it is not directly related to the immediate relief of eye pain and photophobia in bacterial conjunctivitis.This action might be more relevant for conditions involving fluid retention or respiratory issues.

Choice D rationale:

Offering an oral analgesic could help manage the resident’s pain, but it does not address the underlying issue of the warm compress potentially worsening the bacterial infection.Pain management is important, but it should be combined with appropriate measures to treat the infection and alleviate symptoms.
