Correct Answer: D

Rationale: Poor wound healing is a common clinical manifestation of type 1 diabetes mellitus. Elevated blood glucose levels in diabetes can lead to impaired wound healing by affecting various cellular processes involved in the healing cascade. Moist skin (Choice A) is not typically associated with type 1 diabetes mellitus. Weight gain (Choice B) is more commonly seen in type 2 diabetes due to insulin resistance. Fluid overload (Choice C) is not a typical clinical manifestation of type 1 diabetes mellitus. Therefore, the correct answer is poor wound healing.

Correct Answer: A

Rationale: The correct answer is A. Most childhood cancers, such as leukemias and sarcomas, affect tissues rather than specific organs, unlike many adult cancers. Choice B is incorrect because childhood cancers may not always be localized when found. Choice C is incorrect as childhood cancers can be responsive to treatment, although treatment approaches may differ from adult cancers. Choice D is incorrect as the majority of childhood cancers cannot be prevented; however, certain risk factors can be managed to reduce the risk of developing cancer.

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.

Correct Answer: B

Rationale: In the scenario described, the priority is to relieve pressure from the umbilical cord protruding from the vaginal opening by gently pushing it back inside using your gloved fingers. This action helps prevent cord compression, maintains blood flow to the fetus, and ensures fetal oxygenation. Massaging the uterus (Choice A) is not appropriate in this situation as it can potentially worsen the cord compression. Placing the mother on her left side and providing rapid transport (Choice C) can be considered after relieving the pressure on the cord. Elevating the mother's lower extremities and providing immediate transport (Choice D) is not the correct approach when dealing with a visible umbilical cord; instead, the focus should be on relieving pressure from the cord to prevent fetal compromise.

Correct Answer: B

Rationale: The correct answer is B: Signs of dehydration. Infants with hypertrophic pyloric stenosis (HPS) are at high risk of dehydration due to frequent vomiting. Assessing for signs of dehydration, such as decreased urine output, dry mucous membranes, and sunken fontanelles, is crucial for early intervention and management. Choices A, C, and D are not the most critical assessments for HPS. The quality of the cry (choice A) may not provide as much relevant information in this case. Coughing up of feedings (choice C) may be a symptom but is not as crucial as assessing for dehydration. Characteristics of the stool (choice D) are important but assessing for signs of dehydration takes precedence due to the immediate risk it poses to the infant's health.
