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 A reason: Introducing popcorn as a healthy snack at 12 months of age is not recommended due to the risk of choking. Popcorn is a choking hazard for young children and should be avoided until they are older.
Choice B reason: Providing 36 oz of milk per day to a toddler may be excessive and can lead to iron deficiency anemia due to the displacement of other iron-rich foods. The American Academy of Pediatrics recommends 16-24 oz of milk per day for toddlers.
Choice C reason: Offering 8 to 10 oz of juice per day to a preschooler exceeds the American Academy of Pediatrics' recommendation of limiting juice to 4-6 oz per day for children 1-6 years old to prevent dental caries and ensure they consume more whole fruits.
Choice D reason: Encouraging a 15-year-old to increase calcium intake is appropriate as adolescence is a critical period for bone development. Adequate calcium intake supports optimal bone growth and density, helping to prevent osteoporosis later in life.
Correct Answer is A
Explanation
Choice A reason: Hyperpyrexia, or extremely high fever, is a common symptom of acetylsalicylic acid (aspirin) poisoning. The body's response to the toxic levels of aspirin can lead to an elevated temperature as part of a systemic inflammatory response.
Choice B reason: Jaundice is not a typical symptom of acute acetylsalicylic acid poisoning. It is more commonly associated with liver conditions that cause an increase in bilirubin levels.
Choice C reason: Neck vein distention is not a common finding in acetylsalicylic acid poisoning. It is often seen in conditions that cause increased pressure in the venous system, such as heart failure.
Choice D reason: Polyuria, or excessive urination, is not a direct symptom of acetylsalicylic acid poisoning. While changes in urination can occur due to renal involvement, hyperpyrexia is a more immediate concern.
