Nursing Elites

1. What illnesses does respiratory hygiene and cough etiquette by the Centers for Disease Control and Prevention (CDC) prevent?

• A. HBV, Hib, and pertussis
• B. HSV, influenza, and HBV
• C. RSV, influenza, and adenovirus
• D. RSV, pertussis, and varicella

Correct answer: C

Rationale: The correct answer is C: RSV, influenza, and adenovirus. The CDC recommends respiratory hygiene and etiquette to prevent the transmission of respiratory syncytial virus (RSV), influenza, adenovirus, and other droplet-transmitted unknown viruses. Choices A, B, and D are incorrect because HBV, Hib, pertussis, HSV, and varicella are not typically transmitted via droplets but through other modes of transmission.

2. What is an important intervention in providing a neutral thermal environment for an LBW infant in an incubator?

• A. Use wool blankets.
• B. Avoid using disposable diapers.
• C. Prevent heat loss.
• D. Closely monitor both incubator and rectal temperatures.

Correct answer: C

Rationale: Preventing heat loss in a low birth weight (LBW) infant is crucial in maintaining a neutral thermal environment. The use of cotton blankets is recommended over wool blankets. Avoiding disposable diapers is not directly related to maintaining a neutral thermal environment. While monitoring temperatures is important, the key intervention is preventing heat loss to ensure the infant's survival.

3. Which pediatric disorder is associated with a 'boot-shaped' heart on a chest x-ray?

• A. Tetralogy of Fallot
• B. Transposition of the great arteries
• C. Coarctation of the aorta
• D. Ventricular septal defect

Correct answer: A

Rationale: The correct answer is A: Tetralogy of Fallot. Tetralogy of Fallot is often associated with a 'boot-shaped' heart appearance on a chest x-ray due to the characteristic heart anatomy in this condition. This appearance is caused by the combination of pulmonary stenosis, overriding aorta, ventricular septal defect, and right ventricular hypertrophy. Choice B, Transposition of the great arteries, is incorrect because it presents with a 'egg-on-a-string' appearance on x-ray due to the abnormal position of the aorta and pulmonary artery. Choice C, Coarctation of the aorta, typically presents with rib notching on x-ray. Choice D, Ventricular septal defect, does not produce the 'boot-shaped' heart appearance seen in Tetralogy of Fallot.

4. 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.

5. What is typically the first sign of puberty in females?

• A. Breast development
• B. Menarche
• C. Pubic hair growth
• D. Axillary hair growth

Correct answer: A

Rationale: The correct answer is A: Breast development (thelarche) is usually the first sign of puberty in females, typically beginning between ages 8 and 13. This marks the start of puberty, followed by pubic hair growth, a growth spurt, and eventually menarche (the onset of menstruation). Pubic hair growth and axillary hair growth usually follow breast development in the sequence of pubertal changes. Therefore, the first noticeable change indicating the onset of puberty in females is the development of breast buds.
