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 are the most common signs and symptoms of leukemia related to bone marrow involvement?

• A. petechiae, infection, fatigue
• B. headache, papilledema, irritability
• C. muscle wasting, weight loss, fatigue
• D. decreased intracranial pressure, psychosis, confusion

Correct answer: A

Rationale: The correct answer is A: petechiae, infection, fatigue. In leukemia, bone marrow involvement leads to a decrease in normal blood cell production, resulting in petechiae (small red or purple spots on the skin), increased susceptibility to infections due to decreased white blood cells, and fatigue from anemia. Choices B, C, and D are incorrect because they do not directly relate to the typical signs and symptoms of leukemia with bone marrow involvement. Headache, papilledema, irritability, muscle wasting, weight loss, decreased intracranial pressure, psychosis, and confusion are not typically associated with leukemia and bone marrow involvement.

3. 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 appropriate age.
• D. buy shoes that close with Velcro rather than laces.

Correct answer: C

Rationale: Moving a child to a regular bed by the appropriate age is not recommended as it can increase the risk of falls. Toddlers should transition to a regular bed only when developmentally ready to prevent accidents. Keeping medications in a medicine cabinet (Choice A) promotes safety by preventing accidental ingestion. Securing gates at entrances to staircases (Choice B) helps prevent falls down stairs. Buying shoes that close with Velcro rather than laces (Choice D) is a good practice to prevent tripping and falling.

4. A nurse is teaching the parents of a child with a diagnosis of type 1 diabetes mellitus about blood glucose monitoring. What should the nurse emphasize?

• A. Checking blood glucose levels before meals and at bedtime
• B. Using a lancet device to obtain blood samples
• C. Using urine test strips for monitoring
• D. Recognizing signs of hypoglycemia

Correct answer: A

Rationale: Checking blood glucose levels before meals and at bedtime is essential for managing type 1 diabetes mellitus. This timing helps in assessing the effectiveness of insulin therapy, making adjustments to insulin doses, and preventing hyperglycemia and hypoglycemia. Option B is incorrect because it focuses on the method of obtaining blood samples rather than the timing of monitoring. Option C is incorrect as urine test strips are not recommended for accurate blood glucose monitoring in type 1 diabetes. Option D, recognizing signs of hypoglycemia, is important but not the primary emphasis when teaching about blood glucose monitoring.

5. A nurse is assessing a child with suspected rheumatic fever. What clinical manifestation is the nurse likely to observe?

• A. Jaundice
• B. Peeling skin on the hands and feet
• C. High fever
• D. Severe joint pain

Correct answer: D

Rationale: The correct answer is D, severe joint pain. Rheumatic fever commonly presents with severe joint pain due to joint inflammation. Jaundice (choice A) is not typically associated with rheumatic fever. Peeling skin on the hands and feet (choice B) is more indicative of conditions like Kawasaki disease. While a high fever (choice C) can be present, it is not as specific to rheumatic fever as severe joint pain. Severe joint pain, along with other criteria like carditis, subcutaneous nodules, erythema marginatum, and Sydenham chorea, are major criteria used in the diagnosis of rheumatic fever.
