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 teaching a group of parents in the daycare center about accident prevention, the nurse explains that young toddlers are prone to injuries from falls. When receiving feedback, the nurse identifies that more teaching is needed when one parent states, 'I will:'

• A. keep medications in a medicine cabinet.
• B. have secured gates at entrances to staircases.
• C. move our child to a regular bed by the age of three.
• D. buy shoes that fasten with Velcro rather than laces.

Correct answer: C

Rationale: The correct answer is C. Moving a child to a regular bed by the age of three can increase the risk of falls as young toddlers may not have the motor skills to safely navigate a larger bed. This indicates a need for more teaching on safety measures. Choices A, B, and D are all appropriate safety measures that can help prevent accidents and injuries in young children. Keeping medications in a medicine cabinet, having secured gates at entrances to staircases, and choosing shoes that fasten with Velcro instead of laces are all good practices to ensure a safe environment for toddlers.

3. The nurse is assessing a 4-year-old client. Which finding suggests to the nurse this child may have a genetic disorder?

• A. The inquiry determines the child had feeding problems.
• B. The child weighs 40 lb (18.2 kg) and is 40 in (101.6 cm) in height.
• C. The child has low-set ears with lobe creases.
• D. The child can hop on one foot but cannot skip.

Correct answer: C

Rationale: Low-set ears with lobe creases are often associated with genetic disorders, such as Down syndrome, and can indicate underlying chromosomal abnormalities. This physical characteristic is a common feature seen in various genetic syndromes. The other choices, including feeding problems, weight and height measurements, and motor skills, are not typically specific indicators of genetic disorders in the absence of other associated features.

4. Why does a cleft lip predispose an infant to infection?

• A. Waste products accumulate along the defect.
• B. There is evidence of inadequate circulation in the defective area.
• C. Nutrition is inadequate due to ineffective feeding.
• D. Mouth breathing dries the oropharyngeal mucous membranes.

Correct answer: D

Rationale: The correct answer is D. Mouth breathing due to a cleft lip can dry the mucous membranes, making them more susceptible to infection. Choice A is incorrect because waste products do not accumulate along the defect to predispose the infant to infection. Choice B is incorrect as there is no evidence of inadequate circulation being a primary factor in infection predisposition in cleft lip cases. Choice C is incorrect because although ineffective feeding may lead to other issues, it is not the main reason for infection predisposition in infants with a cleft lip.

5. What is the priority nursing intervention for a child with juvenile idiopathic arthritis (JIA)?

• A. Encouraging a diet high in protein
• B. Administering nonsteroidal anti-inflammatory drugs (NSAIDs)
• C. Applying heat to affected joints
• D. Providing range-of-motion exercises

Correct answer: B

Rationale: The priority nursing intervention for a child with juvenile idiopathic arthritis (JIA) is to administer nonsteroidal anti-inflammatory drugs (NSAIDs). NSAIDs help manage pain and inflammation associated with JIA, making them crucial in providing relief to the child. Encouraging a diet high in protein (Choice A) may be beneficial for overall health but is not the priority in managing JIA symptoms. Applying heat to affected joints (Choice C) can provide comfort but does not address the underlying inflammation. Providing range-of-motion exercises (Choice D) is important for maintaining joint mobility but is not the priority intervention when managing acute symptoms of JIA.
