Nursing Elites

1. Which of the following conditions is characterized by a 'machine-like' murmur in children?

• A. Patent ductus arteriosus
• B. Ventricular septal defect
• C. Atrial septal defect
• D. Coarctation of the aorta

Correct answer: A

Rationale: The correct answer is A, Patent ductus arteriosus. This condition is characterized by a continuous 'machine-like' murmur due to abnormal blood flow between the aorta and pulmonary artery. Ventricular septal defect (choice B) is characterized by a harsh holosystolic murmur, atrial septal defect (choice C) typically presents with a fixed split S2 and a pulmonary flow murmur, and coarctation of the aorta (choice D) is associated with a systolic murmur in the back and bilateral lower extremities.

2. What is the most effective method to prevent infection in the newborn?

• A. Using disposable items
• B. Practicing proper hand hygiene by staff and family
• C. Administering prophylactic antibiotics
• D. Isolating the newborn from others

Correct answer: B

Rationale: The most effective method to prevent infection in newborns is by practicing proper hand hygiene by staff and family. This is crucial as it helps reduce the transmission of infectious agents, protecting vulnerable newborns. Using disposable items may help, but proper hand hygiene is more effective. Administering prophylactic antibiotics without a specific indication can lead to antibiotic resistance and is not recommended. Isolating the newborn from others is not practical and may not be necessary if proper hand hygiene is maintained.

3. What changes could the school nurse implement at the school to help reduce students’ risk for developing type 2 diabetes?

• A. Increase the amount of daily physical activity.
• B. Decrease the amount of daily physical activity.
• C. Test each child’s urine monthly.
• D. Teach parents to avoid administering aspirin to their child.

Correct answer: A

Rationale: Increasing physical activity helps improve insulin sensitivity and can prevent or delay the onset of type 2 diabetes in children. Regular physical activity is a key component in managing weight and reducing the risk of chronic diseases. Decreasing physical activity (Choice B) would not be beneficial in reducing the risk of type 2 diabetes. Testing each child’s urine monthly (Choice C) is not directly related to preventing type 2 diabetes. Teaching parents to avoid administering aspirin to their child (Choice D) is important for Reye's syndrome prevention but not directly related to reducing the risk of type 2 diabetes.

4. An intravenous line is needed in a school-age child. What medication is an appropriate analgesic for use with this patient?

• A. TAC (tetracaine, epinephrine [Adrenalin], cocaine) 15 minutes before the procedure.
• B. A transdermal fentanyl (Duragesic) patch at the site of venipuncture.
• C. EMLA (eutectic mixture of local anesthetics) immediately before the procedure.
• D. LMX (4% liposomal lidocaine cream) 30 minutes before the procedure.

Correct answer: D

Rationale: LMX is an effective analgesic agent when applied to the skin 30 minutes before a procedure. It eliminates or reduces the pain from most procedures involving skin puncture. TAC provides skin anesthesia about 15 minutes after application to nonintact skin, making it more suitable for wound suturing. Transdermal fentanyl patches are designed for continuous pain control, not rapid pain control needed for a procedure like venipuncture. EMLA, for maximum effectiveness, must be applied approximately 60 minutes before the procedure, making it less suitable for immediate pain relief required for intravenous line placement.

5. The nurse is preparing an airborne infection isolation room for a patient. Which communicable disease does the patient likely have?

• A. Varicella
• B. Pertussis
• C. Influenza
• D. Scarlet fever

Correct answer: A

Rationale: Varicella (chickenpox) is an airborne infectious disease, requiring isolation to prevent the spread of the virus.
