A nurse is caring for a school-age child who has a prescription for amoxicillin 320 mg PO every 8 hr for 10 days. Available is amoxicillin suspension 400 mg/5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["4"]
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.

Correct Answer is C
Explanation
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 C
Explanation
A. Visual acuity 20/30 bilaterally: Visual acuity of 20/30 bilaterally indicates relatively good vision in both eyes, but it does not necessarily indicate strabismus. Strabismus is related to eye alignment rather than visual acuity.
B. Peripheral vision 70° downward: Peripheral vision refers to the ability to see objects outside the direct line of vision. While changes in peripheral vision can occur in various eye conditions, such as glaucoma, it is not specific to strabismus.
C. Movement of the uncovered eye during a cover test: This is the correct option. During a cover test, one eye is covered while the other eye fixates on an object. If the uncovered eye moves to try to align with the covered eye, it may indicate strabismus or a misalignment of the eyes.
D. Light reflects symmetrically within each pupil during a corneal light reflex test: A corneal light reflex test assesses the alignment of the eyes by observing the reflection of light on the corneas. While asymmetry in the corneal light reflex can indicate strabismus, the description provided in this option suggests that the light reflects symmetrically within each pupil, which is a normal finding.
