A nurse is caring for a 6-month-old infant who has gastroenteritis. Which of the following findings should the nurse identify as a manifestation of severe dehydration?
Produces tears when crying
Sunken anterior fontanel
Weight loss of 5%
Capillary refill time 3 seconds
The Correct Answer is B
Choice A reason: Producing tears when crying is not typically a sign of severe dehydration. In fact, the ability to produce tears may suggest that the infant is not severely dehydrated.
Choice B reason: A sunken anterior fontanel is a classic sign of severe dehydration in infants. The fontanel, which is the soft spot on the top of a baby's head, can appear sunken when there is significant fluid loss.
Choice C reason: While weight loss can be a sign of dehydration, a 5% weight loss alone does not necessarily indicate severe dehydration. Other clinical signs should also be considered.
Choice D reason: A capillary refill time of 3 seconds is at the upper limit of normal. Prolonged capillary refill time can be a sign of dehydration, but it is not as specific as a sunken anterior fontanel for severe dehydration.

Correct Answer is D
Explanation
Choice Areason: An upper respiratory infection 2 days ago, if the child is currently well, is not a contraindication for the MMR vaccine. Vaccines can be given to children with a minor illness.
Choice Breason: A temperature of 37.2° C (99°F) is a mild elevation and is not a contraindication for receiving the MMR vaccine. Vaccination can proceed if the child is only mildly ill.
Choice C reason: A family history of seizures is not a contraindication for the MMR vaccine. While there is a small risk of febrile seizures, the benefits of vaccination outweigh the risks.
Choice D reason: An allergy to neomycin is a contraindication for the MMR vaccine because neomycin is used in the vaccine production process. Children with a known severe allergic reaction to neomycin should not receive the vaccine.
Correct Answer is D
Explanation
Choice A reason: While exposure to secondhand smoke is unhealthy and should be avoided, it is not commonly listed as a trigger for seizures. The primary concern with secondhand smoke is its impact on respiratory health.
Choice Breason: A prolonged headache can be a symptom of various conditions, but it is not generally considered a direct trigger for seizures. However, if a headache is related to a neurological condition, it may be associated with an increased risk of seizures.
Choice Creason: Decreased temperature, or being cold, is not typically a trigger for seizures. Seizure triggers are usually related to changes in the body's internal environment or external stimuli that affect the nervous system.
Choice D reason: Inadequate sleep is a well-known trigger for seizures. Sleep deprivation can lead to increased seizure activity in individuals with seizure disorders. Ensuring adequate and regular sleep is an important part of managing seizure disorders.
