Before administering an antibiotic that can cause nephrotoxicity, which laboratory value is most important for the practical nurse (PN) to review?

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.

Troponin I and CK-MB are cardiac enzymes that are released into the bloodstream when the heart muscle is injured or necrotic. Elevated levels of these enzymes indicate that the client has suffered a myocardial infarction (MI) or heart attack. The damaged heart tissue can impair the electrical conduction system of the heart and cause abnormal heart rhythms or dysrhythmias, which can be life-threatening. The PN should monitor the client's cardiac status closely and report any changes to the charge nurse.

The other options are not correct because:

B. The client is not at risk for pulmonary embolism, which is a blockage of a pulmonary artery by a blood clot or other material. Pulmonary embolism does not cause elevated cardiac enzymes, but it can cause chest pain, shortness of breath, and hypoxia.

C. The client is not at risk for recurrent long-term angina pain, which is chest pain caused by reduced blood flow to the heart muscle due to narrowed or blocked coronary arteries. Angina pain does not cause elevated cardiac enzymes, but it can be a warning sign of an impending MI.

D. The lab results do not indicate risk factors for transient ischemic attack (TIA), which is a temporary interruption of blood flow to a part of the brain due to a clot or plaque. TIA does not cause elevated cardiac enzymes, but it can cause neurological symptoms such as weakness, numbness, or speech difficulties.
