The nurse is implementing care for a school-age child admitted to the pediatric intensive care unit with diabetic ketoacidosis (DKA). Which prescribed intervention should the nurse implement first?

Correct Answer: A

Rationale: The correct first intervention when managing a child with diabetic ketoacidosis is to begin intravenous saline solution to address dehydration and restore electrolyte balance. Rehydration is essential to improve perfusion and correct electrolyte imbalances. Administering insulin without addressing dehydration can potentially lead to further complications. Placing the child on a cardiac monitor or pulse oximetry monitor is important but not the initial priority in managing DKA.

Correct Answer: B

Rationale: Limiting screen time is a crucial recommendation to prevent childhood obesity. Excessive screen time is associated with sedentary behavior and increased consumption of unhealthy snacks, leading to weight gain. Encouraging high-calorie snacks (Choice A) contradicts the goal of preventing obesity. While fast food as a treat (Choice C) can be consumed occasionally, it should not be encouraged as a regular practice. Allowing the child to eat freely (Choice D) without restrictions can lead to overeating and unhealthy dietary habits, contributing to obesity risk.

Correct Answer: A

Rationale: The correct answer is A: 'They may occur in minor illnesses.' Febrile seizures can occur even in minor illnesses, particularly in young children, and are often triggered by a rapid increase in body temperature. Choice B is incorrect because the cause of febrile seizures is not always readily identified. Choice C is incorrect as febrile seizures commonly occur in children aged 6 months to 5 years, which includes the toddler years. Choice D is incorrect as febrile seizures are slightly more common in males than females.

Correct Answer: B

Rationale: The correct answer is to limit screen time when preventing childhood obesity. Excessive screen time is associated with a sedentary lifestyle and can lead to increased consumption of unhealthy foods. Encouraging high-calorie snacks (choice A) contradicts the goal of preventing obesity. While fast food as an occasional treat (choice C) can be acceptable in moderation, it should not be encouraged as a preventive measure against obesity. Allowing the child to eat freely (choice D) without guidance can lead to overconsumption of unhealthy foods and contribute to obesity risk.

Correct Answer: A

Rationale: A heart rate below 100 beats/min in a newborn indicates the need for positive pressure ventilation to improve oxygenation. Providing positive pressure ventilations helps in assisting the newborn's breathing efforts to ensure adequate oxygenation. Choice B, providing blow-by oxygen, may not be sufficient to address the underlying issue of inadequate breathing. Choice C, assessing the newborn's skin condition and color, is important but not the most immediate action needed for a heart rate below 100 beats/min. Choice D, starting chest compressions, is not indicated as the infant is breathing spontaneously and has a heart rate, albeit lower than normal, which does not warrant chest compressions.

Correct Answer: D

Rationale: The Resiliency model of family stress, adjustment, and adaptation is the appropriate theory in this scenario. This model focuses on identifying risks and protective factors that help families achieve positive outcomes despite challenges. Duvall's developmental theory primarily focuses on family life cycle stages, Friedman's structural functional theory emphasizes the interdependence of family members, and Von Bertalanffy's general system theory applied to families looks at the family as a dynamic system. These theories do not specifically address the concept of resilience and adaptation in the face of stressors like homelessness.

Correct Answer: C

Rationale: The priority nursing action after corrective surgery for hypertrophic pyloric stenosis (HPS) is to assess the IV site for infiltration. This is crucial as it ensures proper fluid administration and prevents complications such as phlebitis or infiltration-related tissue damage. Applying restraints (Choice A) would not be appropriate in this situation as it is not related to the immediate post-operative care of an infant with an IV infusion. Administering a mild sedative (Choice B) is not indicated as the primary concern post-surgery is monitoring the IV site and the infant's response to the surgery. Attaching the nasogastric tube to wall suction (Choice D) is not the priority at this time, as assessing the IV site takes precedence to prevent potential complications.

Correct Answer: C

Rationale: In acute glomerulonephritis, weight loss is most likely due to the reduction of edema. Edema is a common symptom of glomerulonephritis, which causes fluid retention and swelling in the body. As treatment progresses and the condition improves, the reduction of edema leads to weight loss. Choices A, B, and D are incorrect as they do not directly address the underlying pathophysiology of acute glomerulonephritis and its impact on weight loss.

Correct Answer: C

Rationale: In this scenario, the correct answer is C. Any vital signs outside the expected range in an infant should be documented and reported, as they may indicate a developing condition that requires prompt attention. Choice A is incorrect because slow respirations in infants should not be dismissed without assessment and documentation. Choice B is incorrect because a drop in respiratory rate in this case was significant and should have been documented. Choice D is incorrect because even though infants have underdeveloped respiratory tracts, any abnormal respiratory rate should be taken seriously and documented for monitoring and intervention if necessary.
