Correct Answer: B

Rationale: The correct answer is B: Signs of dehydration. Assessing for signs of dehydration is crucial in infants with hypertrophic pyloric stenosis (HPS) because they are at high risk due to frequent vomiting. Dehydration can lead to serious complications if not promptly addressed. Choices A, C, and D are not the priority assessments for HPS. While the quality of the cry can provide some information on the infant's distress level, dehydration assessment takes precedence. Coughing up feedings may not be specific to HPS, and characteristics of the stool, although important in general assessments, are not the priority in this situation.

Correct Answer: B

Rationale: Allowing the child to play with a favorite toy while taking the medication is the best approach to gain cooperation. This strategy can help distract and calm the child during the medication administration process. Choice A may not be as effective with a young child who may not fully understand the explanation. Offering a reward (choice C) may reinforce negative behavior and create a dependency on rewards for cooperation. Giving the medication with food (choice D) may not always be appropriate and may not address the cooperation aspect.

Correct Answer: C

Rationale: The most appropriate nursing diagnosis for a child with acute glomerulonephritis is fluid volume excess related to decreased plasma filtration. Acute glomerulonephritis is characterized by inflammation of the glomeruli in the kidneys, leading to decreased plasma filtration and retention of fluid. This results in fluid volume excess rather than fluid deficit (choice B) or fluid accumulation in tissues and third spaces (choice D). The diagnosis of 'risk for injury related to malignant process and treatment' (choice A) is not directly related to the pathophysiology of acute glomerulonephritis.

Correct Answer: A

Rationale: The correct answer is monitoring fluid and electrolyte balance. Gastroenteritis is characterized by inflammation of the gastrointestinal tract, leading to fluid loss. Maintaining fluid and electrolyte balance is essential in managing gastroenteritis to prevent dehydration and electrolyte imbalances. Encouraging regular exercise (Choice B) is not a priority in the acute phase of gastroenteritis when the focus is on rehydration and symptom management. Administering antipyretics (Choice C) may be considered for fever management but is not the priority over monitoring fluid and electrolyte balance. Administering antibiotics (Choice D) is not routinely indicated for viral gastroenteritis, which is a common cause of the condition in children.

Correct Answer: D

Rationale: Poor wound healing is a common clinical manifestation of type 1 diabetes mellitus. High blood glucose levels in diabetes can impair the body's ability to heal wounds effectively. Choices A, B, and C are incorrect. Moist skin is not a typical clinical manifestation of type 1 diabetes; instead, skin may become dry due to dehydration. Weight gain is unlikely as type 1 diabetes is characterized by weight loss. Fluid overload is also uncommon in type 1 diabetes, which is more commonly associated with dehydration due to frequent urination.
