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.While cystic fibrosis is characterized by a high concentration of sodium chloride in sweat due to defective chloride channels, this is not the cause of the barrel chest and clubbing of the fingers.
B.The barrel chest and clubbing of the fingers are often seen in children with cystic fibrosis due to chronic hypoxia (lack of oxygen). Chronic lung infections, airway obstruction, and respiratory insufficiency associated with cystic fibrosis lead to prolonged low oxygen levels, which can result in these physical changes.
C.Decreased respiratory capacity, often due to the chronic respiratory issues associated with cystic fibrosis, can result in a barrel chest (increased chest diameter due to air trapping) and clubbing of the fingers (a sign of chronic hypoxia).
D.Decreased respiratory capacity (due to thick mucus and airway obstruction) does contribute to chronic respiratory issues in cystic fibrosis, but the direct cause of the barrel chest and clubbing is the chronic lack of oxygen (hypoxia) rather than decreased capacity alone. The changes in the chest and fingers are a result of prolonged oxygen deprivation.
Correct Answer is B
Explanation
A. Exposure to contaminated body fluid:
HIV can be transmitted through exposure to contaminated body fluids such as blood, semen, vaginal fluids, and breast milk. However, in the context of infants, mother-to-child transmission is the primary mode of concern.
B. Mother-to-child transmission:
Mother-to-child transmission, also known as perinatal or vertical transmission, is the major means of HIV transmission in infants. It can occur during pregnancy, childbirth, or breastfeeding when the virus is passed from an HIV-positive mother to her child.
C. Blood transfusions:
While HIV transmission through blood transfusions was a concern in the past, current blood screening and testing procedures have significantly reduced this risk. It is not a major means of transmission in the infant population.
D. Sharing of infected needles:
The sharing of infected needles is a risk factor for HIV transmission among individuals who use injection drugs. However, this mode of transmission is not relevant to infants, as they are not typically exposed to such risk factors.
