For the past six hours, a postoperative male client has refused pain medication because he believed that he could "tough it out." When an opioid analgesic is administered, the client has difficulty obtaining a satisfactory level of comfort. Which action is best for the practical nurse (PN) to use in assisting this client to deal with his pain?

The correct answer is choice B, Serum creatinine. Choice A rationale:

The white blood cell count (WBC) is an important parameter for assessing the body's immune response to infections. While it can provide valuable information about the presence of an infection, it is not directly related to nephrotoxicity. Therefore, it is not the most important laboratory value to review before administering an antibiotic that can cause nephrotoxicity.

Choice B rationale:

Serum creatinine is a crucial laboratory value to assess kidney function. It is a waste product that is filtered by the kidneys, and its level in the blood is a reliable indicator of kidney function. If the serum creatinine level is elevated, it suggests impaired kidney function, which can be a warning sign of nephrotoxicity. Reviewing the serum creatinine level before administering nephrotoxic antibiotics is essential to ensure that the client's kidneys are functioning adequately and to avoid potential harm.

Choice C rationale:

Hemoglobin and hematocrit are indicators of the client's red blood cell count and blood's oxygen-carrying capacity. While these values can provide information about the client's overall health status, they are not directly related to nephrotoxicity. Therefore, they are not the most important laboratory values to review in this particular scenario.

Choice D rationale:

Serum calcium levels are essential for assessing bone health, nerve function, and muscle contractions. However, they are not directly related to nephrotoxicity, and reviewing serum calcium levels alone would not provide sufficient information about kidney function. Hence, it is not the most critical value to review before administering nephrotoxic antibiotics

The correct answer is Choice B. Refer to the dermatologist for prescribed long-term therapy. Choice A rationale:

Omitting specific foods like chocolate, carbonated drinks, and fried foods from the diet is a common misconception about acne management. While a healthy diet can contribute to overall skin health, there is no direct evidence to support the notion that avoiding these foods alone will effectively treat acne. Acne is a complex skin condition influenced by various factors, including hormonal imbalances and genetics.

Choice B rationale:

Referring the client to a dermatologist for prescribed long-term therapy is the most appropriate recommendation for managing acne. Dermatologists are medical professionals specialized in skin conditions and can provide personalized treatment plans based on the client's specific type and severity of acne. They may prescribe topical or oral medications, such as retinoids, antibiotics, or hormonal therapy, to effectively manage acne.

Choice C rationale:

Expressing blackheads and using an exfoliating scrub is not a recommended approach for managing acne. Manual extraction of blackheads can lead to skin irritation, infection, and scarring. Exfoliating scrubs can also cause damage to the skin, especially if used too frequently or if the acne is inflamed.

Choice D rationale:

Washing the hair and skin daily with mild soap and warm water is a general hygiene recommendation and may help to keep the skin clean, but it is not a specific and effective treatment for acne. Acne requires targeted therapies to address its underlying causes and manage its symptoms.
