1. Which cardiac defects are associated with tetralogy of Fallot?

A. Right ventricular hypertrophy, atrial and ventricular defects, and mitral valve stenosis
B. Origin of the aorta from the right ventricle and of the pulmonary artery from the left ventricle
C. Right ventricular hypertrophy, ventricular septal defect, pulmonic stenosis, and overriding aorta
D. Altered connection between the pulmonary artery and the aorta, right ventricular hypertrophy, and an atrial septal defect

Correct answer: C

Rationale: Tetralogy of Fallot is characterized by a combination of four specific cardiac defects: right ventricular hypertrophy, ventricular septal defect, pulmonic stenosis, and overriding aorta. Choice A is incorrect as it includes mitral valve stenosis, which is not typically part of tetralogy of Fallot. Choice B describes transposition of the great arteries rather than tetralogy of Fallot. Choice D includes an atrial septal defect, which is not part of the classic presentation of tetralogy of Fallot.

2. What foods are appropriate for a 30-month-old toddler on a regular diet?

A. Hamburger with bun and grapes
B. Chicken fingers and french fries
C. Hot dog with bun and potato chips
D. Macaroni and cheese and Cheerios

Correct answer: D

Rationale: Macaroni and cheese and Cheerios are appropriate choices for a 30-month-old toddler on a regular diet. These foods are easy to chew, digest, and are generally well-liked by toddlers. Option A, a hamburger with bun and grapes, may be difficult for a toddler to handle due to the size of the hamburger and grapes pose a choking hazard. Option B, chicken fingers and french fries, may be too greasy and processed for a toddler's developing digestive system. Option C, hot dog with bun and potato chips, is also not ideal as hot dogs can be a choking hazard and potato chips are high in salt and may not provide adequate nutrition.

3. Which of the following techniques represents the most appropriate method of opening the airway of an infant with no suspected neck injury?

A. lift up the chin and hyperextend the neck
B. tilt the head back without hyperextending the neck
C. gently lift the chin while maintaining slight flexion of the neck
D. perform the technique as you would for an older child or adult

Correct answer: B

Rationale: The correct technique for opening the airway of an infant with no suspected neck injury is to tilt the head back without hyperextending the neck. This method helps to keep the airway open without risking injury to the infant's delicate neck structures. Choice A, lifting up the chin and hyperextending the neck, can potentially harm the infant's neck. Choice C, gently lifting the chin while maintaining slight flexion of the neck, is not as effective as tilting the head back. Choice D is incorrect as infants require a different approach compared to older children or adults due to their anatomical differences.

4. During the second week of hospitalization for intravenous antibiotic therapy, a 2-year-old toddler whose family is unable to visit often smiles easily, goes to all the nurses happily, and does not express interest in the parent when the parent does visit. The parent tells the nurse, 'I am pleased about the adjustment but somewhat concerned about my child’s reaction to me.' How should the nurse respond?

A. The child is repressing feelings towards the parent.
B. Routines have been established, and the child feels safe.
C. The child has given up fighting and accepts the separation.
D. Behavior has improved because the child feels better physically.

Correct answer: C

Rationale: The correct answer is C. The child's behavior of smiling easily, interacting happily with nurses, and showing disinterest in the parent when they visit indicates that the child has emotionally withdrawn and accepted the separation. This response suggests that the child may have given up fighting against the separation from the parent due to prolonged hospitalization. Choices A, B, and D are incorrect. Choice A about the child repressing feelings towards the parent is not supported by the scenario. Choice B about routines and feeling safe does not address the emotional aspect of the child's behavior. Choice D about improved behavior due to feeling better physically does not explain the emotional dynamics at play in the child's behavior.

5. When teaching the parents of a child with a diagnosis of type 1 diabetes mellitus about insulin administration, what should the nurse emphasize?

A. Rotate injection sites
B. Administer insulin before meals
C. Store insulin in the refrigerator
D. Administer insulin at bedtime

Correct answer: A

Rationale: The correct answer is to rotate injection sites. This practice helps prevent lipodystrophy, a localized loss of fat tissue that can affect insulin absorption. By rotating sites, the child can avoid developing lumps or indentations in the skin where insulin is repeatedly injected. Administering insulin before meals (choice B) may be necessary for certain types of insulin but is not the priority when teaching about insulin administration. Storing insulin in the refrigerator (choice C) is important for maintaining its potency, but it is not the primary emphasis when teaching about insulin administration. Administering insulin at bedtime (choice D) may be necessary based on the child's insulin regimen but is not the primary consideration for teaching injection techniques and site rotation.
