Nursing Elites

1. Based on developmental norms for a 5-year-old child, at what apical pulse did the nurse decide to withhold a scheduled dose of digoxin (Lanoxin) elixir and notify the health care provider?

• A. 60 beats/min
• B. 70 beats/min
• C. 90 beats/min
• D. 100 beats/min

Correct answer: C

Rationale: For a 5-year-old child, an apical pulse below 90 beats/min is a reason to withhold digoxin. Digoxin is a medication commonly used to treat heart conditions, and its administration is based on heart rate parameters. A pulse rate below 90 beats/min indicates bradycardia. In pediatric patients, bradycardia below this threshold may be a sign of toxicity or potential adverse effects of digoxin, necessitating withholding the medication and informing the healthcare provider. Choices A, B, and D are incorrect as they represent pulse rates above the threshold for withholding digoxin in a 5-year-old child.

2. A 5-year-old child is admitted to the hospital with a diagnosis of bacterial meningitis. What is the priority nursing intervention?

• A. Administering antibiotics
• B. Isolating the child
• C. Monitoring vital signs
• D. Administering fluids

Correct answer: B

Rationale: The priority nursing intervention for a child admitted with bacterial meningitis is isolating the child. Isolation is crucial to prevent the spread of the highly contagious infection to other patients and healthcare workers. Administering antibiotics (Choice A) is important but isolating the child takes precedence to contain the spread of the infection. Monitoring vital signs (Choice C) and administering fluids (Choice D) are essential aspects of care but do not address the immediate need to prevent transmission of the infection.

3. A child with a cardiac malformation associated with left-to-right shunting. What does this type of congenital disorder lead to primarily?

• A. Elevated hematocrit
• B. Severe growth retardation
• C. Clubbing of the fingers and toes
• D. Increased blood flow to the lungs

Correct answer: D

Rationale: Left-to-right shunting in a cardiac malformation results in increased blood flow to the lungs. This increased blood flow can lead to pulmonary hypertension and heart failure if left untreated. Elevated hematocrit (Choice A) is not a characteristic directly associated with left-to-right shunting. Severe growth retardation (Choice B) is not a typical manifestation of this type of congenital disorder. Clubbing of the fingers and toes (Choice C) is more commonly seen in conditions like chronic respiratory or cardiac diseases, not specifically with left-to-right shunting and associated cardiac malformations.

4. A child with a diagnosis of leukemia is receiving chemotherapy. What is the priority nursing intervention?

• A. Monitoring for signs of infection
• B. Providing nutritional support
• C. Monitoring for signs of bleeding
• D. Monitoring for signs of pain

Correct answer: A

Rationale: The priority nursing intervention for a child with leukemia receiving chemotherapy is monitoring for signs of infection. Chemotherapy can suppress the immune system, increasing the risk of infections. Detecting and managing infections promptly is crucial to prevent complications and improve outcomes. Providing nutritional support is important, but infection prevention takes precedence due to the immediate threat it poses to the child's health. Monitoring for signs of bleeding is relevant in leukemia due to decreased platelet count, but infection surveillance is more critical. Monitoring for signs of pain is essential, but addressing infections promptly is the priority to prevent further deterioration in the child's condition.

5. When teaching a class about trisomy 21, the instructor would identify the cause of this disorder as:

• A. nondisjunction.
• B. X-linked recessive inheritance.
• C. genomic imprinting.
• D. autosomal dominant inheritance.

Correct answer: A

Rationale: Trisomy 21, also known as Down syndrome, is caused by nondisjunction, which is an error in cell division that leads to the presence of an extra chromosome 21. This additional chromosome alters the normal genetic makeup, resulting in the characteristics associated with Down syndrome. Therefore, the correct answer is nondisjunction (Choice A). Choices B, C, and D are incorrect because Trisomy 21 is not caused by X-linked recessive inheritance, genomic imprinting, or autosomal dominant inheritance. Understanding the specific genetic mechanism involved in Trisomy 21 is crucial for grasping the basis of this chromosomal disorder.
