Nursing Elites

1. An infant is diagnosed with Hirschsprung disease. What nursing intervention is essential before surgery?

• A. Administering antibiotics
• B. Ensuring bowel rest
• C. Performing regular enemas
• D. Maintaining NPO status

Correct answer: D

Rationale: Maintaining NPO (nothing by mouth) status is essential before surgery for a patient with Hirschsprung disease to prevent aspiration. Administering antibiotics, ensuring bowel rest, and performing regular enemas are not the priority interventions before surgery for this condition. Administering antibiotics may be necessary in the postoperative period to prevent infection, ensuring bowel rest can be beneficial but is not the priority, and performing regular enemas is not typically recommended before surgery for Hirschsprung disease.

2. A child is admitted with extensive burns. The nurse notes burns on the child’s lips and singed nasal hairs. The nurse should suspect that the child has a(n)

• A. chemical burn
• B. inhalation injury
• C. electrical burn
• D. hot-water scald

Correct answer: B

Rationale: Burns on the lips and singed nasal hairs indicate inhalation injury, suggesting the child has inhaled hot gases or smoke. This presentation is common in cases where the respiratory tract is exposed to hot gases or smoke, leading to potential airway compromise. Choice A, chemical burn, is incorrect because there is no mention of exposure to chemicals, and the symptoms described are more indicative of inhalation injury. Choice C, electrical burn, is incorrect as there is no evidence of electrical involvement in the scenario provided. Choice D, hot-water scald, is incorrect because the presence of singed nasal hairs points more towards inhalation injury than a scald from hot water, emphasizing the need to prioritize airway management and respiratory support.

3. When teaching a class about trisomy 21, the instructor would identify the cause of this disorder as:

• A. nondisjunction.
• B. X-linked recessive inheritance.
• C. genomic imprinting.
• D. autosomal dominant inheritance.

Correct answer: A

Rationale: Trisomy 21, also known as Down syndrome, is caused by nondisjunction, which is an error in cell division that leads to the presence of an extra chromosome 21. This additional chromosome alters the normal genetic makeup, resulting in the characteristics associated with Down syndrome. Therefore, the correct answer is nondisjunction (Choice A). Choices B, C, and D are incorrect because Trisomy 21 is not caused by X-linked recessive inheritance, genomic imprinting, or autosomal dominant inheritance. Understanding the specific genetic mechanism involved in Trisomy 21 is crucial for grasping the basis of this chromosomal disorder.

4. What is the priority nursing responsibility when a 3-year-old child in a crib has a clamped jaw and is having a tonic-clonic seizure?

• A. Apply restraints.
• B. Administer oxygen.
• C. Protect the child from self-injury.
• D. Insert a plastic airway in the child’s mouth.

Correct answer: C

Rationale: During a tonic-clonic seizure, the priority nursing responsibility is to protect the child from self-injury. Applying restraints is not recommended during a seizure as it can lead to further harm. Administering oxygen may be necessary after the seizure to support oxygenation, but it is not the priority during the seizure itself. Inserting a plastic airway is also not indicated as the jaw is clamped, and the child should not have anything placed in the mouth during a seizure. Therefore, the correct action is to ensure the child's safety by protecting them from self-injury, preventing harm from uncontrolled movements and potential falls.

5. A nurse is caring for an infant with phenylketonuria (PKU). What diet should the nurse anticipate will be ordered by the health care provider?

• A. Fat-free
• B. Protein-enriched
• C. Phenylalanine-free
• D. Low-phenylalanine

Correct answer: D

Rationale: A low-phenylalanine diet is required for infants with PKU to prevent the buildup of phenylalanine, which can lead to brain damage.
