A nurse is providing teaching to the parent of a child who has a new prescription for methylphenidate. Which of the following instructions should the nurse include?
"Monitor your child for excessive sleepiness."
"Administer the medication with a caffeinated beverage."
"Administer the second dose of the medication at lunch time."
"Monitor your child for weight gain."
The Correct Answer is C
A. "Monitor your child for excessive sleepiness."
Methylphenidate is a central nervous system stimulant used to treat attention deficit hyperactivity disorder (ADHD). It typically causes insomnia or decreased need for sleep rather than excessive sleepiness. This option is incorrect, as it does not align with the expected side effects of the medication.
B. "Administer the medication with a caffeinated beverage."
Caffeine is also a stimulant, and combining it with methylphenidate could increase the risk of side effects such as increased heart rate, anxiety, or jitteriness. This instruction is incorrect and unsafe.
C. "Administer the second dose of the medication at lunch time."
Methylphenidate is usually given in divided doses, with the second dose often administered at lunchtime. This timing helps maintain therapeutic levels during the school day while minimizing the risk of insomnia. This option is correct and appropriate for managing the medication.
D. "Monitor your child for weight gain."
A common side effect of methylphenidate is appetite suppression, which can lead to weight loss, not weight gain. This option is incorrect, as the nurse should instruct the parent to monitor for weight loss instead.

Correct Answer is B
Explanation
A. Coarctation of the aorta
Coarctation of the aorta involves a narrowing of the aorta, leading to decreased blood flow to the lower body. It is not associated with increased pulmonary blood flow.
B. Patent ductus arteriosus
Patent ductus arteriosus (PDA) is a congenital heart defect where the ductus arteriosus, a fetal blood vessel that usually closes shortly after birth, remains open. This allows blood to flow from the aorta into the pulmonary artery, increasing pulmonary blood flow. Therefore, option B is correct.
C. Tetralogy of Fallot
Tetralogy of Fallot is a congenital heart defect characterized by four abnormalities, including a ventricular septal defect (VSD), pulmonary stenosis, right ventricular hypertrophy, and an overriding aorta. While it can lead to cyanosis due to right-to-left shunting, it is not primarily associated with increased pulmonary blood flow.
D. Tricuspid atresia
Tricuspid atresia involves the absence of the tricuspid valve, leading to a lack of direct blood flow from the right atrium to the right ventricle. It usually presents with decreased pulmonary blood flow rather than increased pulmonary blood flow.
Correct Answer is ["4"]
Explanation
To calculate the dose of amoxicillin for a child, the nurse needs to use the following formula:
Dose (mL) = prescribed dose (mg) / concentration (mg/mL)
In this case, the prescribed dose is 320 mg and the concentration is 400 mg/5 mL. Plugging these values into the formula, we get:
Dose (mL) = 320 mg / (400 mg/5 mL)
Dose (mL) = 320 mg x (5 mL/400 mg)
Dose (mL) = 4 mL
Therefore, the nurse should administer 4 mL of amoxicillin suspension per dose.
