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: B

Rationale: In a pediatric patient presenting with altered mental status, high fever, and a generalized rash, seizures are a significant concern. Febrile seizures can occur in children with high fevers and may lead to further complications. It is crucial to monitor for seizures and be prepared to manage them promptly. Vomiting, combativeness, and respiratory distress are also important considerations in pediatric patients; however, given the clinical presentation described, seizures take priority as they are a common complication in this scenario.

Correct Answer: D

Rationale: Patent ductus arteriosus (PDA) is an abnormal connection between the pulmonary artery and the aorta. In a fetus, the ductus arteriosus is a normal connection between these two vessels, allowing blood to bypass the lungs. However, it should close shortly after birth. When it remains open (patent), it leads to PDA. Choices A, B, and C do not accurately describe PDA. Choice A describes an enlarged aorta, choice B describes a ventricular septal defect, and choice C describes pulmonary stenosis, which are different cardiac conditions.

Correct Answer: D

Rationale: Initiating pain assessment with a standardized pain scale is crucial in managing pain effectively during a sickle cell crisis. This step allows the nurse to objectively evaluate the child's pain level and tailor the pain management plan accordingly. Administering medication without a proper assessment could lead to inappropriate pain management. Using guided imagery and therapeutic touch may be beneficial as adjunct therapies but should not replace the initial pain assessment. Meperidine is not typically the first-line choice for pain management in sickle cell crisis due to its potential for neurotoxic metabolites.

Correct Answer: A

Rationale: Infection is the greatest risk for an infant with exstrophy of the bladder due to the exposure of the bladder and surrounding tissues. The bladder mucosa and adjacent tissues being exposed increase the susceptibility to infections. Dehydration (Choice B) is not the primary concern in this condition. Urinary retention (Choice C) is less likely as exstrophy of the bladder usually presents with constant dribbling of urine. Intestinal obstruction (Choice D) is not directly related to exstrophy of the bladder.
