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. When caring for a child diagnosed with cystic fibrosis, what is the priority nursing intervention?

• A. Administering pancreatic enzymes
• B. Providing respiratory therapy
• C. Encouraging physical activity
• D. Encouraging frequent handwashing

Correct answer: A

Rationale: The priority nursing intervention when caring for a child with cystic fibrosis is administering pancreatic enzymes. Cystic fibrosis is a genetic disorder that affects the digestive and respiratory systems. Administering pancreatic enzymes is crucial in aiding digestion as patients with cystic fibrosis often have pancreatic insufficiency. While providing respiratory therapy and encouraging physical activity are important aspects of care for individuals with cystic fibrosis, administering pancreatic enzymes takes precedence in addressing the malabsorption issues associated with the condition. Encouraging frequent handwashing is also essential in infection control, but it is not the priority intervention specifically related to managing cystic fibrosis.

3. A healthcare professional is educating a group of parents on preventing childhood obesity. What should the professional recommend?

• A. Encourage high-calorie snacks
• B. Limit screen time
• C. Encourage fast food as a treat
• D. Allow the child to eat freely

Correct answer: B

Rationale: The correct answer is to limit screen time when preventing childhood obesity. Excessive screen time is associated with a sedentary lifestyle and can lead to increased consumption of unhealthy foods. Encouraging high-calorie snacks (choice A) contradicts the goal of preventing obesity. While fast food as an occasional treat (choice C) can be acceptable in moderation, it should not be encouraged as a preventive measure against obesity. Allowing the child to eat freely (choice D) without guidance can lead to overconsumption of unhealthy foods and contribute to obesity risk.

4. The nurse is caring for a 15-year-old boy who has sustained burn injuries. The nurse observes the burn developing a purplish color with discharge and a foul odor. The nurse suspects which infection?

• A. Burn wound cellulitis.
• B. Invasive burn cellulitis.
• C. Burn impetigo.
• D. Staphylococcal scalded skin syndrome.

Correct answer: B

Rationale: Invasive burn cellulitis is characterized by the burn developing a dark brown, black, or purplish color with discharge and a foul odor. This description aligns with the symptoms observed in the 15-year-old boy. Burn wound cellulitis (Choice A) typically presents with erythema, edema, warmth, and tenderness at the burn site, without the characteristic changes seen in this case. Burn impetigo (Choice C) is a superficial infection characterized by honey-colored crusts, not consistent with the purplish color and foul odor described. Staphylococcal scalded skin syndrome (Choice D) is a condition caused by exotoxins produced by Staphylococcus aureus, leading to widespread desquamation of the skin, but it does not typically present with the specific findings mentioned in the scenario.

5. A parent and 3-month-old infant are visiting the well-baby clinic for a routine examination. What should the nurse include in the accident prevention teaching plan?

• A. Remove small objects from the floor.
• B. Cover electric outlets with safety plugs.
• C. Remove toxic substances from low areas.
• D. Test the temperature of water before bathing.

Correct answer: D

Rationale: Testing the temperature of water before bathing is crucial to prevent burns, which is a significant risk for infants due to their sensitive skin. Infants have delicate skin that can easily be burned by water that is too hot. Testing the water temperature before bathing ensures that the water is at a safe and comfortable level for the infant. While choices A, B, and C are also important in accident prevention, such as reducing choking hazards, preventing electric shocks, and avoiding poisoning, testing the water temperature before bathing is the most immediate and direct action to prevent harm to the infant during bathing.
