A nurse is administering 30 mg/kg/day of amoxicillin every six hours to a 48.6 lb client. The concentration available is 0.2 g/5 mL. How many mL will the nurse administer to the client per dose? Round to the nearest tenths place. Record numerical answer only.
The Correct Answer is ["4.1"]
Convert the client's weight from pounds (lb) to kilograms (kg).
Weight in kg = 48.6 lb / 2.2 lb/kg
= 22.09 kg.
Calculate the total daily desired dose in milligrams (mg).
Total daily desired dose (mg) = Desired dose (mg/kg/day) × Weight (kg)
= 30 mg/kg/day × 22.09 kg
= 662.7 mg/day.
Determine the number of doses per day.
Doses are administered every six hours, so Number of doses per day = 24 hours / 6 hours/dose
= 4 doses/day.
Calculate the dose per administration in milligrams (mg).
Dose per administration (mg) = Total daily desired dose (mg) / Number of doses per day
= 662.7 mg / 4 doses
= 165.675 mg.
Convert the available concentration from grams (g) to milligrams (mg).
Available concentration = 0.2 g/5 mL
1 g = 1000 mg
Available concentration in mg/mL = (0.2 g × 1000 mg/g) / 5 mL
= 200 mg / 5 mL
= 40 mg/mL.
Calculate the volume in milliliters (mL) to administer per dose.
Volume (mL) = Desired dose per administration (mg) / Available concentration (mg/mL)
= 165.675 mg / 40 mg/mL
= 4.141875 mL.
Round the answer to the nearest tenths place.
= 4.1mL

Correct Answer is C
Explanation
A. Epilepsy: Smoking during pregnancy is not linked to epilepsy in the newborn. Epilepsy is typically associated with genetic or neurological factors rather than maternal smoking.
B. Type 1 diabetes mellitus: Type 1 diabetes is an autoimmune condition and is not directly associated with smoking during pregnancy. Smoking can increase the risk of gestational diabetes, but not Type 1 diabetes.
C. Growth restriction: Smoking during pregnancy is a major risk factor for intrauterine growth restriction (IUGR). The toxins in cigarettes can reduce blood flow to the placenta, limiting the oxygen and nutrients available to the fetus, which can result in smaller-than-expected growth.
D. Hearing loss: While maternal smoking can increase the risk of preterm birth and other complications, it is not a direct cause of hearing loss in newborns. Hearing loss is more commonly linked to genetic factors or infections.
Correct Answer is C
Explanation
A. Prevention of oral infection: While oral infection prevention is important, the main concern for a newborn with cleft lip and palate is ensuring proper nutrition. Difficulty with feeding due to the cleft requires immediate intervention to ensure adequate nourishment before surgery.
B. Visual stimulation: Visual stimulation is beneficial for infant development but is not the primary focus in preoperative care for a newborn with a cleft lip and palate. The priority is addressing feeding challenges that affect the baby’s nutritional intake.
C. Nutrition: Infants with cleft lip and palate often struggle with feeding, making proper nutrition the most critical concern. Special feeding techniques are needed to ensure the infant receives enough nourishment before surgery to promote growth and health.
D. Prevention of pneumonia: Although preventing pneumonia is essential, the immediate focus for a newborn with cleft lip and palate is ensuring adequate nutrition. Nutritional support is necessary to maintain overall health and reduce the risk of complications, including pneumonia.
