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. The nurse is selecting a site to begin an intravenous infusion on a 2-year-old child. The superficial veins on his hand and arm are not readily visible. What intervention should increase the visibility of these veins?

• A. Gently tap over the site.
• B. Apply a cold compress to the site.
• C. Raise the extremity above the level of the body
• D. Use a rubber band as a tourniquet for 5 minutes.

Correct answer: A

Rationale: Gently tapping over the site helps dilate the veins and increase visibility. Applying a cold compress or raising the extremity above the body level constricts the veins, making them harder to access. Prolonged tourniquet use can cause discomfort and venous congestion.

3. The parents of a young child ask the nurse for suggestions about discipline. When discussing the use of time-outs, which should the nurse include?

• A. Send the child to his or her room if the child has one.
• B. A general rule for length of time is 1 hour per year of age.
• C. Select an area that is safe and nonstimulating, such as a hallway.
• D. If the child cries, refuses, or is more disruptive, try another approach.

Correct answer: C

Rationale: Time-outs should be in a safe, nonstimulating area, with the length typically being 1 minute per year of the child's age, not 1 hour.

4. Where is the best place to observe for the presence of petechiae in dark-skinned individuals?

• A. Face
• B. Buttocks
• C. Oral mucosa
• D. Palms and soles

Correct answer: C

Rationale: The oral mucosa and conjunctivae are the best places to observe petechiae in dark-skinned individuals because these areas have less pigmentation.

5. Which condition is characterized by a 'seal-like' barking cough in children?

• A. Croup
• B. Asthma
• C. Bronchitis
• D. Pneumonia

Correct answer: A

Rationale: Croup is the correct answer. Croup is characterized by a 'seal-like' barking cough due to inflammation and narrowing of the upper airways, particularly the larynx and trachea. It is most common in young children and can cause significant respiratory distress, especially at night. Treatment often includes humidified air and corticosteroids. Asthma (choice B) typically presents with wheezing and shortness of breath, not a barking cough. Bronchitis (choice C) is characterized by productive cough with mucus, not a barking cough. Pneumonia (choice D) often presents with fever, productive cough, and chest pain, not a barking cough.
