a 10-year-old is hit in the head with a baseball during practice and is diagnosed with concussion, even though no loss of consciousness occurred. the primary care nurse practitioner is evaluating the child 2 weeks after the injury and learns that the child is still experiencing some sleepiness every day. the neurological exam is normal. the child and the parent are adamant that the child be allowed to return to play baseball. what will the nurse practitioner recommend?

Explanation:

Question 3

1. For teaching parents to brush with fluoride toothpaste: Infants this age (9 months) may not be ready for toothpaste use, and swallowing fluoride toothpaste can be a risk, so this is incorrect.
2. Applying sodium fluoride varnish: This is a common and safe practice to promote dental health in infants with emerging teeth, especially when local water has fluoride (but varnish provides additional protection).
3. Prescribing oral fluoride supplementation: Since the local water supply has fluoride, supplementation is not necessary and can lead to excess fluoride intake.
4. Encouraging initial dental appointment: While dental care is important, the immediate action for promoting healthy dentition here is the varnish application, and initial dental appointments for infants are often not the first step in this context.

(Assuming options include things like "Recommend a gradual return to play", "Allow immediate return", "Wait for all symptoms to resolve", etc. Since the child still has sleepiness (post - concussion symptom) and neurological exam is normal, the nurse practitioner should recommend a gradual return to play or wait until symptoms resolve. But with partial text, the key is that post - concussion, even with normal neuro exam, residual symptoms (sleepiness) mean the child should not return to play yet and needs further monitoring or a gradual return plan. If one of the options is to recommend waiting until sleepiness resolves or a graduated return, that would be correct. For example, if an option is "Recommend the child wait until sleepiness resolves before returning to play", that would be correct as post - concussion symptoms (like sleepiness) need to resolve before returning to contact sports like baseball.)

(Note: Since the full options are not visible, the above is a general explanation based on pediatric concussion management guidelines. If you can provide the full options, a more precise answer can be given.)

Answer:

B. Apply sodium fluoride varnish to the infant’s teeth
