Nursing Elites

1. The parents of a newborn with phenylketonuria (PKU) need help and support in adhering to specific dietary restrictions. They ask the nurse, “How long will our child have to be on this diet?” How should the nurse respond?

• A. “We are still not sure; you should discuss this with your health care provider.”
• B. “If your baby does well, foods containing protein can gradually be introduced.”
• C. “Your child needs to be on this diet at least through adolescence and into adulthood.”
• D. “This is a lifelong problem, and it is recommended that dietary restrictions must be continued.”

Correct answer: D

Rationale: The correct answer is D: “This is a lifelong problem, and it is recommended that dietary restrictions must be continued.” Phenylketonuria (PKU) is a metabolic disorder where the body cannot process phenylalanine properly. The diet for PKU must be continued lifelong to prevent cognitive and developmental issues, as phenylalanine buildup can cause irreversible damage. Choice A is incorrect because the nurse should provide information about the lifelong nature of the dietary restrictions for PKU. Choice B is incorrect as it suggests reintroducing protein-containing foods, which is not recommended for individuals with PKU. Choice C is incorrect as it underestimates the duration of the necessary dietary restrictions for PKU.

2. While assessing a child admitted for an asthma attack, a nurse in the emergency department observes large welts and scars on the child's back. What additional information must be included in the nurse’s assessment?

• A. History of an injury
• B. Signs of child abuse
• C. Presence of food allergies
• D. Recent recovery from chickenpox

Correct answer: B

Rationale: The correct answer is B: Signs of child abuse. When a nurse observes large welts and scars on a child, it raises concern for possible child abuse. It is crucial for the nurse to assess further for signs of abuse, document findings, and report appropriately to protect the child. Choice A, history of an injury, is not specific to potential abuse and may not provide insight into the current situation. Choice C, presence of food allergies, is not directly related to the observed welts and scars. Choice D, recent recovery from chickenpox, is also unrelated to the signs of abuse and does not impact the immediate assessment of the child's safety.

3. A child with a cardiac malformation associated with left-to-right shunting is being cared for by a nurse. What does the nurse consider to be the major characteristic of this type of congenital disorder?

• A. Elevated hematocrit
• B. Severe growth retardation
• C. Clubbing of the fingers and toes
• D. Increased blood flow to the lungs

Correct answer: D

Rationale: The major characteristic of a cardiac malformation associated with left-to-right shunting is increased blood flow to the lungs. This increased flow can lead to pulmonary hypertension and heart failure if left untreated. Elevated hematocrit (Choice A) is not a typical characteristic of this condition. Severe growth retardation (Choice B) is not directly associated with left-to-right shunting. Clubbing of the fingers and toes (Choice C) is more commonly seen in conditions involving chronic hypoxia.

4. When caring for an alert 4-year-old child with a mild airway obstruction, respiratory distress, a strong cough, and normal skin color, what should be included?

• A. Back blows, abdominal thrusts, transport
• B. Oxygen, avoiding agitation, transport
• C. Assisting ventilations, back blows, transport
• D. Chest thrusts, finger sweeps, transport

Correct answer: B

Rationale: The correct approach for a child with a mild airway obstruction, respiratory distress, and normal skin color includes providing oxygen to support breathing, avoiding agitation that could worsen the situation, and arranging for transport to a healthcare facility. Option A is incorrect because abdominal thrusts are not recommended in a mild airway obstruction scenario, and back blows are typically used for choking. Option C is incorrect because assisting ventilations may not be necessary in a child with a strong cough and normal skin color. Option D is incorrect because chest thrusts are not recommended for a mild airway obstruction, and finger sweeps are used for foreign body airway obstructions.

5. The instructor is educating a group of students about myelination in a child. Which statement by the students indicates that the teaching was successful?

• A. Myelination continues into adolescence.
• B. The process occurs in a head-to-toe fashion.
• C. Myelination speeds up nerve impulses.
• D. Myelination increases the specificity and efficiency of nerve impulses.

Correct answer: B

Rationale: The correct answer is B. Myelination occurs in a cephalocaudal (head-to-toe) pattern, improving nerve function progressively. Choice A is incorrect because myelination continues beyond 4 years of age and into adolescence. Choice C is incorrect as myelination speeds up nerve impulses rather than slowing them down. Choice D is incorrect because myelination increases the specificity and efficiency of nerve impulses, making them more focused and precise.
