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. The nurse is obtaining a health history from parents of a 4-month-old boy with congenital hypothyroidism. What would the nurse most likely assess?

• A. The child's growth is above normal for his age.
• B. The child is active and playful.
• C. The skin appears pink and healthy.
• D. It is difficult to keep the child awake.

Correct answer: D

Rationale: The correct answer is D. Congenital hypothyroidism in infants often leads to lethargy and difficulty staying awake due to low thyroid hormone levels. Assessing the child's ability to stay awake is crucial in identifying signs of hypothyroidism. Choices A, B, and C are incorrect because above-normal growth, being active and playful, and having healthy-looking skin are not typical manifestations of congenital hypothyroidism. Instead, infants with hypothyroidism may exhibit poor weight gain, decreased activity, and dry, pale skin.

3. What is an early sign of congestive heart failure that the nurse should recognize?

• A. Tachypnea
• B. Bradycardia
• C. Inability to sweat
• D. Increased urinary output

Correct answer: A

Rationale: Tachypnea, which refers to rapid breathing, is an early sign of congestive heart failure. In heart failure, the heart's inability to pump efficiently can lead to fluid accumulation in the lungs, causing the child to breathe faster to try to compensate for the decreased oxygen exchange. Bradycardia (slow heart rate) is not typically associated with congestive heart failure; instead, it may indicate a different issue. Inability to sweat is not a common early sign of congestive heart failure. Increased urinary output is not a typical early sign of congestive heart failure; instead, it may be a sign of other conditions like diabetes or kidney issues.

4. A child with Duchenne muscular dystrophy is to receive prednisone as part of their treatment plan. After teaching the child's parents about this drug, which statement by the parents indicates the need for additional teaching?

• A. We should give this drug after he eats something.
• B. We need to watch carefully for possible infections.
• C. The drug should not be stopped abruptly.
• D. He might experience weight gain with this drug.

Correct answer: A

Rationale: The correct statement should be, 'We should give this drug after he eats something.' Prednisone should be administered with food to help prevent gastrointestinal upset. Choice B is correct as monitoring for infections is important due to prednisone's immunosuppressive effects. Choice C is correct as prednisone should not be stopped suddenly to prevent withdrawal symptoms. Choice D is correct as weight gain is a common side effect of prednisone.

5. 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.
