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. A healthcare provider is preparing a 2-year-old child for surgery. What preoperative teaching should be provided to this child?
- A. Explaining the procedure in simple terms
- B. Using a doll to demonstrate the procedure
- C. Showing pictures of the hospital environment
- D. Allowing the child to play with medical equipment
Correct answer: B
Rationale: Using a doll to demonstrate the procedure is the most appropriate preoperative teaching method for a 2-year-old child. It helps them understand what to expect in a non-threatening way by providing a visual representation of the upcoming surgery. Explaining the procedure in simple terms may be too abstract for a child of this age, as they may not fully comprehend verbal explanations. Showing pictures of the hospital environment may not be as effective as using a doll, as it may not provide a concrete understanding of the actual procedure. Allowing the child to play with medical equipment is unsafe and does not adequately prepare them for the surgery, as it may lead to misunderstandings or fear regarding the equipment's actual use during the surgery.
3. A child with a diagnosis of appendicitis is scheduled for surgery. What preoperative intervention is important for the nurse to perform?
- A. Administering antibiotics
- B. Maintaining strict NPO status
- C. Encouraging fluid intake
- D. Monitoring for signs of infection
Correct answer: D
Rationale: The correct preoperative intervention for a child with appendicitis scheduled for surgery is to monitor for signs of infection. This is crucial to ensure that any potential infections are promptly identified and managed before surgery. Administering antibiotics, maintaining strict NPO status, and encouraging fluid intake are important interventions in various clinical situations but are not the priority in this scenario. Administering antibiotics may be part of the treatment plan but is typically prescribed by a physician. Maintaining NPO status is important to prevent complications related to anesthesia but may not directly address the specific needs of a child with appendicitis. Encouraging fluid intake is generally beneficial for hydration but may not be the primary concern before surgery for appendicitis.
4. 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: Petechiae, infection, and fatigue are common signs and symptoms of leukemia related to bone marrow involvement. Petechiae are small red or purple spots on the skin caused by bleeding under the skin due to low platelet counts. Infection susceptibility increases due to decreased white blood cells from compromised bone marrow function. Fatigue is a common symptom of anemia resulting from decreased red blood cell production. Choices B, C, and D are incorrect as they do not align with the typical signs and symptoms of leukemia associated with bone marrow dysfunction.
5. A 2-year-old child who was admitted to the hospital for further surgical repair of a clubfoot is standing in the crib, crying. The child refuses to be comforted and calls for the mother. As the nurse approaches the crib to provide morning care, the child screams louder. Knowing that this behavior is typical of the stage of protest, what is the most appropriate nursing intervention?
- A. Use comforting measures while holding the child.
- B. Fill the basin with water and proceed to bathe the child.
- C. Sit by the crib and bathe the child later when the anxiety decreases.
- D. Postpone the bath for a day because a child this upset should not be traumatized further.
Correct answer: C
Rationale: During the stage of protest, children may exhibit distress and cling to familiar figures, resisting interactions with others. The most appropriate nursing intervention is to sit by the crib, offer comfort, and wait until the child's anxiety decreases before proceeding with bathing. This approach allows the child to feel supported and gradually transition to accepting care. Choice A is incorrect because forcing comfort may escalate the child's distress. Choice B is inappropriate as it disregards the child's emotional state and rushes into the bathing procedure. Choice D is not ideal as it suggests delaying care for an extended period, which may not address the child's immediate needs for comfort and hygiene.
