A college student comes to the school's health clinic troubled by urinary frequency and burning with right lower back pain. Which intervention should the nurse implement first?

C. Herpes zoster is caused by the reactivation of the varicella-zoster virus, the same virus that causes chickenpox (varicella). Asking whether everyone at home has already had varicella helps assess the risk of exposure to susceptible individuals who could potentially develop chickenpox upon exposure to the herpes zoster rash.
A. Sharing combs and brushes may increase the risk of transmitting head lice, fungal infections, or bacterial infections, but it is not directly relevant to the assessment of herpes zoster.
B. Dry patches on the feet and hands may be indicative of various dermatological conditions such as eczema or psoriasis, but they are not specific to herpes zoster. Herpes zoster typically presents as a painful rash with clusters of fluid-filled blisters along a specific dermatome
D. Asking about the effectiveness of antifungal creams is relevant if the client is being treated for a fungal infection, but it does not provide information specific to herpes zoster.

D. In a client presenting with urinary symptoms and lower back pain, measuring the temperature and pulse rate is essential for assessing for signs of systemic infection, such as fever (elevated temperature) and tachycardia (elevated pulse rate). These vital signs can help determine the urgency of the situation and guide further assessment and management.
A. Palpating the right flank for tenderness may be appropriate to assess for signs of kidney involvement, such as in pyelonephritis. However, this intervention is not the first priority. Assessing for systemic signs of infection, such as fever, is more urgent.
B. Evaluating the urine for a strong odor may provide additional information about the student's symptoms, but it is not the first intervention priority.

C. Testing the urine for the presence of hematuria (blood in the urine) is an important diagnostic step in evaluating urinary symptoms, but it is not the first intervention priority. Hematuria may be present in various conditions, including UTIs, kidney stones, or other urinary tract disorders.
