1. Pertussis vaccination should begin at which age?

Correct answer: B

Rationale: The DTaP vaccine, which includes pertussis, is typically started at 2 months of age as part of the recommended immunization schedule.

2. Which is a complication that can occur after abdominal surgery if pain is not managed?

Correct answer: A

Rationale: Poorly managed pain after abdominal surgery can lead to complications like atelectasis due to shallow breathing, which may occur if the child avoids deep breaths because of pain.

3. Which laboratory value at the time of diagnosis should the nurse anticipate would determine the worst prognosis for a child with leukemia?

Correct answer: D

Rationale: A high white blood cell count (leukocytes of 275,000/mcL) at diagnosis is associated with a worse prognosis in leukemia because it indicates a more aggressive disease with a higher tumor burden. Slow response to chemotherapy (choice A) is a consequence of the aggressive disease and not a determining factor at diagnosis. Platelets of 150,000/mcL (choice B) and leukocytes less than 10,000/mcL (choice C) are within normal ranges and not indicative of a worse prognosis in leukemia.

4. What is the most effective way to prevent the spread of hand, foot, and mouth disease in a daycare setting?

Correct answer: A

Rationale: Handwashing is indeed the most effective way to prevent the spread of hand, foot, and mouth disease in children. Proper hand hygiene helps in removing and killing germs that can cause infections. While isolating sick children and disinfecting toys are important measures to prevent the spread of diseases, they are not as effective as handwashing. Encouraging vaccination, in this case, is not relevant since there is no specific vaccine available for hand, foot, and mouth disease.

5. What amount of fluid loss occurs with moderate dehydration?

Correct answer: B

Rationale: Moderate dehydration is typically defined as a loss of 50 to 90 mL/kg of body weight. This amount reflects significant fluid loss that requires medical attention but is not yet severe.
