Correct Answer: D

Rationale: The correct nursing intervention essential before surgery for an infant with Hirschsprung disease is maintaining NPO (nothing by mouth) status. This is important to prevent aspiration during and after the surgical procedure. Administering antibiotics (Choice A) may be necessary in some cases but is not the priority intervention before surgery. Ensuring bowel rest (Choice B) is not directly related to preparing for surgery and may not be the most critical intervention. Performing regular enemas (Choice C) is not recommended before surgery for Hirschsprung disease as it can aggravate the condition.

Correct Answer: C

Rationale: Postpartum hemorrhage can lead to shock due to excessive bleeding. Oxygen should be provided to support oxygenation. Treatment for shock, which includes maintaining vital signs and perfusion, is crucial. Uterine massage helps prevent further bleeding by promoting uterine contraction. This combination of interventions is essential for managing postpartum hemorrhage effectively. Choices A, B, and D lack the comprehensive approach needed for managing postpartum hemorrhage, as they do not address the treatment of shock, which is vital in this scenario.

Correct Answer: C

Rationale: The correct answer is C. At the age of 8, children are typically eager to take on responsibilities and participate in self-care activities. This is a crucial developmental characteristic to consider when educating a child about managing a chronic condition like type 1 diabetes. Choice A is incorrect as children at this age are usually in the concrete operational stage, not abstract level, of cognition. Choice B is incorrect because while peer influence is important, it does not reach its peak at this age. Choice D is incorrect as exploring self-identity is more characteristic of adolescence, not 8-year-old children.

Correct Answer: B

Rationale: Vomiting and poor appetite are common symptoms of neuroblastoma, a malignancy that arises from neural crest cells in the adrenal glands or sympathetic nervous system. This tumor can cause abdominal swelling due to its location and size, leading to symptoms like vomiting and decreased appetite. The presence of a maculopapular rash on the palms (Choice A) is not a typical finding associated with neuroblastoma. Irritability and failure to thrive (Choice C) are nonspecific symptoms that can be seen in various conditions but are not specifically indicative of neuroblastoma. Auscultation revealing wheezing with diminished lung sounds (Choice D) may suggest respiratory conditions rather than neuroblastoma.

Correct Answer: D

Rationale: The correct answer is D. The grasp reflex and startle reflex (Moro reflex) are normal in newborns but typically disappear as the infant's nervous system matures and voluntary control develops. At around five months of age, these reflexes are replaced by voluntary movements as part of the normal developmental process. Choices A, B, and C are incorrect. Choice A suggests delaying a decision until further assessment, which is not necessary as the disappearance of these reflexes is a normal part of infant development. Choice B implies a developmental delay, which is not the case as these reflexes naturally disappear with age. Choice C recommending additional sensory stimulation is unnecessary and not the reason for the absence of these reflexes.
