Nursing Elites

1. A healthcare professional is reviewing the laboratory report of a child with tetralogy of Fallot that indicates an elevated RBC count. What does the professional identify as the cause of the polycythemia?

• A. Low tissue oxygen needs
• B. Tissue oxygen needs
• C. Diminished iron level
• D. Hypertrophic cardiac muscle

Correct answer: B

Rationale: The correct answer is B: Tissue oxygen needs. Polycythemia occurs as the body's response to chronic hypoxia by increasing RBC production to enhance oxygen delivery. In tetralogy of Fallot, a congenital heart defect, the heart's structure causes reduced oxygen levels in the blood. This chronic hypoxia stimulates the bone marrow to produce more red blood cells, leading to an elevated RBC count. Choice A is incorrect as low blood pressure is not directly related to polycythemia in this context. Choice C, diminished iron level, is not the cause of polycythemia in tetralogy of Fallot. Choice D, hypertrophic cardiac muscle, is not the primary cause of the elevated RBC count in this case.

2. A group of students is reviewing information about the various types of insulin used to treat type 1 diabetes. The students demonstrate understanding of the information when they identify which of these insulins as having the longest duration?

• A. Lispro
• B. Regular
• C. NPH
• D. Glargine

Correct answer: D

Rationale: The correct answer is Glargine (Lantus) as it has the longest duration of action among the insulins listed, lasting 12 to 24 hours. Lispro (A) and Regular (B) are rapid-acting insulins with shorter durations of action. NPH (C) is an intermediate-acting insulin with a duration of action of about 12-16 hours. Therefore, Glargine is the correct choice for the insulin with the longest duration.

3. A parent of an 11-month-old infant who has a cleft palate asks the nurse why it was recommended that closure of the palate should be done before the age of 2. How should the nurse respond?

• A. “After age 2, surgery is frightening and should be avoided if possible.”
• B. “Eruption of the 2-year molars often complicates the surgical procedure.”
• C. “As your child gets older, the palate gets wider and more difficult to repair.”
• D. “Surgery should be performed before your child starts to use faulty speech patterns.”

Correct answer: D

Rationale: Closure of the cleft palate is recommended before the age of 2 to prevent the development of faulty speech patterns. Performing surgery at a younger age helps avoid speech difficulties that may arise if the repair is delayed. Choice A is incorrect as it focuses on fear, not the developmental aspect. Choice B is incorrect as the eruption of molars is not the primary reason for early surgery. Choice C is incorrect because the difficulty of repair is not solely related to the width of the palate but also to speech development.

4. A parent brings an 18-month-old toddler to the clinic. The parent states, 'My child is so difficult to please, has temper tantrums, and annoys me by throwing food from the table.' What is the nurse’s best response?

• A. “Toddlers need discipline to prevent the development of antisocial behaviors.”
• B. “Toddlers are learning to assert independence, and this behavior is expected at this age.”
• C. “It is best to leave the toddler alone in the crib after calmly explaining why the behavior is unacceptable.”
• D. “This is the way a toddler expresses needs, and this behavior is acceptable during the initiative stage of development.”

Correct answer: B

Rationale: The correct answer is B: “Toddlers are learning to assert independence, and this behavior is expected at this age.” At 18 months, toddlers are in the stage of developing autonomy and independence. They may exhibit behaviors like temper tantrums and defiance as they assert their independence and test limits. It is crucial for parents and caregivers to understand that these behaviors are typical for toddlers at this age. Choice A is incorrect because discipline should be age-appropriate and focus on positive reinforcement rather than preventing antisocial behaviors. Choice C is inappropriate as leaving a toddler alone in a crib after explaining unacceptable behavior is not a recommended approach and can lead to feelings of abandonment. Choice D is inaccurate as the described behavior is more related to asserting independence rather than the initiative stage of development.

5. You are called to a residence for a 'sick' 5-year-old child. When you arrive and begin your assessment, you note that the child is unconscious with a respiratory rate of 8 breaths/min and a heart rate of 50 beats/min. Management of this child should consist of

• A. 100% oxygen via a non-rebreathing mask and rapid transport
• B. positive pressure ventilations with a BVM device and rapid transport
• C. chest compressions, artificial ventilations, and rapid transport
• D. back blows and chest thrusts while attempting artificial ventilations

Correct answer: C

Rationale: In a 5-year-old child who is unconscious with a respiratory rate of 8 breaths/min and a heart rate of 50 beats/min, the priority is to initiate chest compressions, artificial ventilations, and rapid transport. These vital interventions are crucial in cases of severe respiratory and cardiovascular compromise. Choice A is incorrect because administering 100% oxygen alone may not address the underlying issues of inadequate ventilation and circulatory support. Choice B is not the most appropriate initial intervention in this scenario; chest compressions should precede positive pressure ventilations. Choice D is incorrect as back blows and chest thrusts are indicated in choking emergencies, not in this case of respiratory and cardiovascular compromise.
