An infant weighing 6 pounds 3 ounces has morphine 0.5 mg IV q 2 hours prn ordered for post op pain. The recommended dosage for a child is 0.1-0.2 mg/kg/dose q2-4 hours prn. Prove mathematically the ordered dose by the physician (mg/kg/dose) and is it safe to give.
The Correct Answer is ["0.1696"]
To calculate the ordered dose by the physician in mg/kg/dose, we need to convert the infant's weight from pounds and ounces to kilograms. One pound is equal to 0.4536 kg and one ounce is equal to 0.02835 kg. Therefore, the infant's weight in kilograms is:
6 x 0.4536 + 3 x 0.02835 = 2.948 kg
The ordered dose by the physician is 0.5 mg IV q 2 hours prn. To find the dose in mg/kg/dose, we divide the dose in mg by the weight in kg:
0.5 / 2.948 = 0.1696 mg/kg/dose
The recommended dosage for a child is 0.1-0.2 mg/kg/dose q2-4 hours prn. The ordered dose by the physician falls within this range, so it is a safe dosage for the infant.

Correct Answer is B
Explanation
A. Internet resources, movies, and television have the most accurate and current information for your adolescent to learn about sexuality issues:
This statement may not be accurate, as the internet, movies, and television can sometimes provide misinformation or biased perspectives. It's crucial to emphasize the importance of reliable and evidence-based sources when adolescents seek information about sexuality.
B. Being honest and straightforward with teenagers will encourage them to ask about subjects like sexuality:
This statement is valuable as it emphasizes open communication. Being honest and straightforward creates an environment where adolescents feel comfortable approaching their caregivers with questions or concerns about sexuality. It promotes trust and a supportive relationship.
C. Most schools have excellent programs to teach adolescents about sex and sexuality:
While some schools do have comprehensive sex education programs, the quality of these programs can vary. Additionally, the involvement of parents and caregivers in discussions about sex and sexuality is essential. Relying solely on school programs may not cover all aspects, and caregivers play a crucial role in reinforcing positive attitudes and values.
D. Teenagers spend so much time with their peers, and that is usually how they find out about sex:
While it's true that peers can influence adolescents, relying solely on peer influence for information about sex may not provide accurate or comprehensive knowledge. Caregivers should aim to create an open and honest dialogue to supplement information from peers and address any misconceptions.
