A nurse is preparing to administer a dexamethasone 1.5 mg/kg/day PO to divide equally every 6 hr to a preschool-age child who weighs 22 lb. Available is dexamethasone oral solution 1 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["3.8"]

Convert the child’s weight to kg:

22 lb ×1kg/2.2lb = 10 kg

Calculate the daily dose:

1.5 mg/kg/day × 10 kg=15mg/day

Divide the total daily dose by the number of doses per day (every 6 hours):

15mg/day ÷ 4doses/day =3.75mg/dose

Convert the dose to mL using the concentration:

3.75mg × 1 mL/1 mg = 3.75 mL

Round to the nearest tenth:

3.75 mL≈ 3.8 mL

Answer: The nurse should administer 3.8 mL per dose.

Correct Answer is C

Explanation

A. "He takes his medication between meals with water." Taking carbamazepine with food helps reduce gastrointestinal upset, but taking it between meals is not critical unless there are specific issues. This is not a priority unless the patient is experiencing significant GI discomfort.

B. "He only sleeps about 5 hours each night." Insufficient sleep can exacerbate seizure disorders, but it is not directly life-threatening. Improving sleep hygiene is important but not the most immediate concern compared to other symptoms.

C. "He seems to be getting a lot more bumps and bruises lately." Increased bruising can indicate thrombocytopenia, a potential side effect of carbamazepine, which can lead to serious bleeding issues. This is the priority as it may indicate a severe adverse effect requiring immediate medical attention and possible adjustment of medication.

D. "He has not been eating as much lately." Decreased appetite can be a side effect of many medications, including carbamazepine, but it is generally not immediately dangerous unless it leads to significant weight loss or nutritional deficiencies. It’s important but not the most urgent concern.

A. Maintain medical asepsis during dressing changes. B. Administer pain medication 30 min to 1 hour before physical therapy. C. Allow the child to set her own schedule for care. D. Provide low-calorie snacks.

Correct Answer is B

Explanation

A. Maintain medical asepsis during dressing changes: While cleanliness is important, aseptic (sterile) technique is typically required for burn care to prevent infection.

B. Administer pain medication 30 min to 1 hour before physical therapy: Pain management is crucial to facilitate participation in physical therapy and improve outcomes.

C. Allow the child to set her own schedule for care: A structured schedule is necessary to ensure regular treatment and care for burns.

D. Provide low-calorie snacks: High-calorie, protein-rich foods are necessary to meet increased metabolic demands for healing.
