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 B
Explanation
Choice A reason: Applying tepid water to the old dressings can help with their removal and may reduce discomfort, but it does not address the greatest risk to the client, which is infection.
Choice B reason: Checking the wound sites for manifestations of infection is crucial as burn injuries compromise the skin's protective barrier, making the client highly susceptible to infections. Infections can lead to further complications and delay healing.
Choice C reason: Performing passive range-of-motion exercises is important for maintaining joint mobility and preventing contractures in burn patients, but it is not the primary intervention for addressing the greatest risk of infection.
Choice D reason: Adjusting the room temperature to 33°C (91.4°F) can create a more comfortable environment for the burn patient and prevent hypothermia, but it is not directly related to the prevention of infection, which is the greatest risk.
Correct Answer is D
Explanation
Choice A reason: Soaking hairbrushes in boiling water is a good practice for decontamination, but it is not specific to the treatment of impetigo, which is a bacterial skin infection.
Choice B reason: Acyclovir is an antiviral medication and would not be effective against impetigo, which is caused by bacteria, typically Staphylococcus aureus or Streptococcus pyogenes.
Choice C reason: Sealing soft toys in a plastic bag for 14 days may help to prevent the spread of infection, but it is not a direct treatment for impetigo itself.
Choice D reason: Applying a bactericidal ointment, such as mupirocin, is a standard treatment for impetigo. It helps to eliminate the bacteria causing the infection and promotes healing of the skin lesions.
