A nurse is caring for a child in diabetic ketoacidosis (DKA). The nurse knows she needs to specifically look at what blood level that will initially be elevated but then shift into the cells once insulin is given.

A. Isotretinoin does not typically alter potassium levels. Routine monitoring of potassium is not indicated in healthy adolescents taking isotretinoin, as the medication does not have known effects on renal potassium handling or cause electrolyte imbalances in this context. Monitoring potassium is only relevant if the patient has other conditions or medications that affect electrolytes.

B. Isotretinoin can cause hyperlipidemia, increasing cholesterol and triglyceride levels, which may raise the risk for pancreatitis or long-term cardiovascular issues. Baseline lipid panels are obtained before starting therapy, with periodic monitoring during treatment to detect and manage elevations promptly.

C. Isotretinoin is not nephrotoxic, meaning it does not typically impair kidney function. Routine monitoring of BUN and creatinine is not necessary unless the adolescent has preexisting kidney disease or other risk factors. Focus should remain on labs directly affected by the medication.

D. Isotretinoin has no significant impact on serum sodium levels. Hyponatremia is not a known complication of isotretinoin therapy, so routine sodium monitoring is unnecessary in otherwise healthy clients. Laboratory monitoring should prioritize liver function tests and lipid profiles, which are more likely to be affected.

A. Burow’s solution is an astringent used for conditions such as weeping eczema or mild skin irritations, but it does not treat bacterial infections like cellulitis. It may provide soothing, but it is not an effective therapeutic intervention for cellulitis.

B. Cryotherapy involves freezing tissue and is used for lesions such as warts or certain skin growths, not for bacterial infections like cellulitis. It has no role in treating acute bacterial infections.

C. Topical antifungals are used for fungal infections such as tinea infections, not for bacterial cellulitis. Cellulitis requires systemic treatment targeting bacteria.

D. Cellulitis is a bacterial infection of the skin and subcutaneous tissue, commonly caused by Staphylococcus aureus or Streptococcus species. The first-line treatment is typically oral antibiotics for mild to moderate infections. Severe cases may require IV antibiotics. Administering antibiotics addresses the underlying infection, reduces inflammation, and prevents the spread of infection.
