A child who weighs 55 pounds receives a prescription for cefotaxime 150 mg/kg/day intravenously in divided doses every 6 hours.
How many mg should the nurse administer each day?
3000 mg.
3300 mg.
3600 mg.
3750 mg.
The Correct Answer is D
Step 1 is to convert the child’s weight from pounds to kilograms since the dosage is prescribed in mg/kg. We know that 1 kg is approximately 2.2 lbs. So, the child’s weight in kg is 55 lbs ÷ 2.2 = 25 kg (rounded to the nearest whole number for simplicity).
Step 2 is to calculate the total daily dosage. The prescription is for 150 mg/kg/day. So, the total daily dosage is 150 mg/kg/day × 25 kg = 3750 mg/day.
So, the correct answer is, after analysing all choices, the nurse should administer 3750 mg of cefotaxime each day.

Correct Answer is B
Explanation
Choice A rationale:
Assessment of tobacco use geared toward adolescents. Rationale: While assessing tobacco use is essential for promoting health in adolescents, the question is about developing a class about mental health and addressing the increase in suicides in the community. Assessing tobacco use is not directly related to this topic. Stress self-management techniques are more relevant.
Choice B rationale:
Exploration of stress self-management techniques. Rationale: This is the correct answer. Addressing stress and teaching adolescents self-management techniques is crucial in the context of mental health promotion and suicide prevention. Adolescents often face stressors, and providing them with effective strategies to manage stress can contribute to their overall well-being.
Choice C rationale:
Video with statistics showing trends in suicide rates. Rationale: While providing statistics about suicide rates can be informative, it may not be the most engaging or effective method for teaching adolescents about mental health and stress management. Interactive activities and skill-building exercises are often more beneficial.
Choice D rationale:
Handouts for local substance abuse treatment centers. Rationale: Providing handouts for substance abuse treatment centers
Correct Answer is C
Explanation
The correct answer is choicec. Administer prescribed stool softener.
Choice A rationale:
Administering prescribed PRN sleep medications can help the client rest, but it is not the highest priority. Managing pain and preventing complications from the laceration are more critical.
Choice B rationale:
Encouraging the use of prescribed analgesic perineal sprays can help manage pain and promote healing, but it is not as crucial as preventing constipation, which can cause significant discomfort and complications.
Choice C rationale:
Administering prescribed stool softeners is the highest priority because a fourth-degree laceration involves the anal sphincter and rectal mucosa.Preventing constipation is essential to avoid straining during bowel movements, which can cause pain and disrupt the healing process.
Choice D rationale:
Encouraging breastfeeding to promote uterine involution is important for postpartum recovery, but it is not directly related to the care of a fourth-degree laceration. Managing pain and preventing complications from the laceration take precedence.
