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. What is important to include in discharge instructions for parents of a child who has had a tonsillectomy?

• A. Encourage the child to gargle with salt water
• B. Encourage fluid intake
• C. Provide the child with hard candy
• D. Apply heat to the neck

Correct answer: B

Rationale: Encouraging fluid intake is essential in the discharge instructions for a child who has had a tonsillectomy. It helps keep the throat moist, aids in preventing dehydration, and promotes healing. Gargling with salt water is not typically recommended after a tonsillectomy as it may irritate the surgical site. Providing the child with hard candy is not advisable as it can irritate the throat and potentially cause harm. Applying heat to the neck is also not recommended post-tonsillectomy as it can increase swelling and discomfort in the surgical area.

3. A child has been diagnosed with gastroesophageal reflux disease (GERD). What position should the nurse recommend the child be placed in after eating?

• A. Supine
• B. Prone
• C. Semi-Fowler's
• D. Trendelenburg

Correct answer: C

Rationale: After eating, it is beneficial to place a child with GERD in a semi-Fowler's position. This position helps prevent reflux by keeping the child's head elevated above the stomach, reducing the chances of gastric contents flowing back into the esophagus. Placing the child supine (lying flat on their back) can worsen reflux symptoms by allowing gravity to work against the natural flow of gastric contents. Prone position (lying on the stomach) is not recommended due to the increased risk of aspiration. Trendelenburg position (feet elevated above head) is also inappropriate as it can lead to increased pressure on the abdomen, potentially worsening reflux symptoms.

4. Congenital heart defects have traditionally been divided into acyanotic or cyanotic defects. Based on the nurse’s knowledge of congenital heart defects, this system in clinical practice is

• A. helpful because it explains the hemodynamics involved
• B. helpful because children with cyanotic defects are easily identified
• C. problematic because cyanosis is rarely present in children
• D. problematic because children with acyanotic heart defects may develop cyanosis

Correct answer: D

Rationale: The classification system of congenital heart defects into acyanotic or cyanotic defects is problematic because children with acyanotic heart defects may develop cyanosis, complicating the differentiation. Cyanosis can occur in some acyanotic defects due to various reasons such as right-to-left shunting or decreased pulmonary blood flow, making the classification based solely on cyanosis misleading. Choice A is incorrect because while the classification may involve hemodynamics, the main issue lies in the potential for acyanotic defects to develop cyanosis. Choice B is incorrect as the ease of identifying children with cyanotic defects does not address the main problem with the classification system. Choice C is also incorrect as the presence of cyanosis is not the only factor determining the classification's validity.

5. What would be important for the nurse to include when teaching an adolescent about tinea pedis?

• A. Keep your feet moist and exposed to the air as much as possible.
• B. Dry the area between your toes thoroughly.
• C. Wear nylon or synthetic socks every day.
• D. Walk barefoot in the school locker room.

Correct answer: B

Rationale: The correct answer is B: 'Dry the area between your toes thoroughly.' When educating an adolescent about tinea pedis, emphasis should be placed on keeping the feet dry, especially between the toes, to minimize the risk of fungal infection. Choice A is incorrect as keeping the feet moist can exacerbate the condition. Choice C is incorrect because nylon or synthetic socks can trap moisture, promoting fungal growth. Choice D is incorrect as walking barefoot in locker rooms increases the risk of contracting tinea pedis from contaminated surfaces.
