Correct Answer: C

Rationale: Children with von Willebrand disease have a deficiency in a clotting protein, putting them at risk of bleeding episodes. The priority nursing intervention for a child with von Willebrand disease is to guard against bleeding injuries to prevent excessive bleeding or hemorrhage. Choices A, B, and D are not the priority interventions for von Willebrand disease. While reducing exposure to infection is important for any hospitalized child, it is not the priority for von Willebrand disease. Eliminating contact with cold objects is more relevant for conditions like Raynaud's disease. Reducing contact with other children is not a specific priority related to managing von Willebrand disease.

Correct Answer: C

Rationale: The most crucial assessment in this scenario is to measure the infant's pulse. Pulse measurement is essential to evaluate the severity of dehydration, which can be a significant concern in a baby experiencing vomiting and diarrhea for several days. Assessing the abdomen for tenderness may provide information on potential causes of symptoms but is not as urgent as monitoring hydration status. Determining exposure to a virus is important for infection control but does not directly address the immediate issue of dehydration. Evaluating the infant's cry, although a form of communication, does not provide critical information regarding the baby's physiological status in this situation.

Correct Answer: B

Rationale: The correct answer is B. Introducing solid foods 4 to 7 days apart is crucial as it allows time to identify any allergic reactions or intolerances to specific foods. This gradual introduction helps parents monitor their infant's response to new foods and pinpoint any potential issues, ensuring the infant's safety and well-being. Choices A, C, and D are incorrect because starting with one tablespoon of the food, mixing new food with rice cereal, and removing foods when the infant refuses them are not recommended practices for introducing solid foods to infants.

Correct Answer: D

Rationale: The correct answer is D. Wearing long sleeves and pants helps prevent tick bites, which can transmit Lyme disease. Ticks carrying Lyme disease are often found in wooded or grassy areas, so covering exposed skin can reduce the risk of being bitten by an infected tick. Choices A, B, and C do not address the specific mode of transmission of Lyme disease through tick bites, making them incorrect.

Correct Answer: A

Rationale: The correct answer is A: 'We should monitor our child's growth and appetite regularly.' Correct monitoring of the child's growth and appetite is crucial when a child is on ADHD medications, especially stimulants, as these medications can have side effects related to growth and appetite. Monitoring these parameters regularly helps in assessing the medication's impact and making any necessary adjustments. Choices B, C, and D are incorrect: B talks about drowsiness, C mentions avoiding stomach upset, and D refers to increased urination and limiting fluid intake. While these are potential side effects of medications, they do not directly address the importance of monitoring growth and appetite, which is crucial in children on ADHD medications.
