Correct Answer: C

Rationale: The correct answer is administering factor VIII. Hemophilia is a genetic disorder characterized by a deficiency in clotting factors, such as factor VIII. Administering factor VIII is crucial in managing bleeding episodes in hemophiliac patients. Pain medication (Choice A) may be necessary but is not the priority in this situation. Monitoring for signs of infection (Choice B) is important for overall care but is not the priority during a bleeding episode. Ensuring a safe environment (Choice D) is also important but not the priority intervention when managing a bleeding episode in a child with hemophilia.

Correct Answer: B

Rationale: The correct priority nursing intervention for a child diagnosed with diabetes insipidus is to monitor fluid balance. Diabetes insipidus is a condition characterized by excessive urination and thirst, which can lead to dehydration. Monitoring fluid balance is essential to prevent dehydration and ensure the child's hydration status remains stable. Administering insulin (Choice A) is not indicated in diabetes insipidus because it is a disorder of the posterior pituitary gland, not the pancreas. Administering diuretics (Choice C) would exacerbate fluid loss in a child already at risk for dehydration. Monitoring vital signs (Choice D) is important but not the priority when compared to maintaining fluid balance in a child with diabetes insipidus.

Correct Answer: C

Rationale: The correct answer is Chickenpox (varicella). This viral disease typically starts with malaise and a highly pruritic rash that begins on the abdomen and then spreads to the face and proximal extremities. Chickenpox can result in serious complications such as pneumonia and encephalitis. Rubella (German measles) presents with a milder rash and is less pruritic than chickenpox. Rubeola (measles) is characterized by a rash that spreads from the head to the trunk. Scarlet fever is caused by group A Streptococcus bacteria and is not a viral illness.

Correct Answer: C

Rationale: The correct answer is C: A ready source of glucose should be available. When managing type 1 diabetes, it is crucial to have a quick source of glucose readily available in case of hypoglycemia. This ensures that the adolescent can quickly raise their blood sugar levels to prevent complications. Choices A, B, and D are incorrect as they do not address the immediate need for glucose in managing hypoglycemia. While it is important for meals to be consumed regularly and in a controlled manner, specifying that they should be eaten at home or foods weighed using a gram scale is not as critical as ensuring a quick source of glucose in emergency situations.

Correct Answer: B

Rationale: The correct technique for opening the airway of an infant with no suspected neck injury is to tilt the head back without hyperextending the neck. This method helps to keep the airway open without risking injury to the infant's delicate neck structures. Choice A, lifting up the chin and hyperextending the neck, can potentially harm the infant's neck. Choice C, gently lifting the chin while maintaining slight flexion of the neck, is not as effective as tilting the head back. Choice D is incorrect as infants require a different approach compared to older children or adults due to their anatomical differences.
