Nursing Elites

1. One of the most critical needs of the infant is control of body temperature. The nurse caring for a newborn warms all equipment that comes in direct contact with the newborn to help prevent which type of heat loss?

• A. Convection
• B. Evaporation
• C. Conduction
• D. Radiation

Correct answer: C

Rationale: The correct answer is Conduction (choice C). Conduction heat loss occurs when the newborn’s skin comes into direct contact with a cooler surface, so warming equipment helps prevent this. Choice A, Convection, is the transfer of heat through air or water currents, not direct contact. Choice B, Evaporation, is the loss of heat through moisture on the skin evaporating, not direct contact. Choice D, Radiation, is the transfer of heat in the form of waves or particles, not direct contact.

2. Which disease would require strict isolation of the patient?

• A. Mumps
• B. Chickenpox
• C. Exanthema subitum (roseola)
• D. Erythema infectiosum (fifth disease)

Correct answer: B

Rationale: The correct answer is B: Chickenpox. Chickenpox is highly infectious and is transmitted through direct contact, droplet spread, and contaminated objects. Due to its high communicability, strict isolation of the patient is necessary to prevent the spread of the disease. Mumps is primarily transmitted through direct contact with the infected person's saliva, with peak contagiousness before the onset of swelling. Exanthema subitum (roseola) has an unknown transmission source. Erythema infectiosum (fifth disease) is contagious before the appearance of symptoms. Therefore, these diseases do not require the same level of strict isolation as chickenpox.

3. What is the most frequent cause of hypovolemic shock in children?

• A. Sepsis
• B. Blood loss
• C. Anaphylaxis
• D. Heart failure

Correct answer: B

Rationale: Hypovolemic shock in children is most frequently caused by blood loss, which can result from trauma, surgery, or gastrointestinal bleeding. Sepsis and anaphylaxis can lead to different types of shock (septic and anaphylactic), and heart failure is related to cardiogenic shock.

4. What should preoperative care of a newborn with an anorectal malformation include?

• A. Frequent suctioning
• B. Gastrointestinal decompression
• C. Feedings with sterile water only
• D. Supine position with head elevated

Correct answer: C

Rationale: Preoperative care for a newborn with an anorectal malformation should include feedings with sterile water only. This approach is important to avoid complications before surgery. Gastrointestinal decompression is necessary to prevent abdominal distention and potential aspiration, making choice B incorrect. Frequent suctioning and placing the newborn in a supine position with the head elevated are not typically part of the preoperative care protocol for an anorectal malformation, thus choices A and D are incorrect.

5. What is the most common cause of bronchiolitis in infants?

• A. Adenovirus
• B. Influenza virus
• C. Respiratory syncytial virus
• D. Parainfluenza virus

Correct answer: C

Rationale: The correct answer is C, Respiratory syncytial virus (RSV). RSV is the leading cause of bronchiolitis, a common respiratory condition in infants that results in inflammation of the small airways in the lung. It is highly contagious and can cause severe respiratory distress in young children, particularly those under 2 years old. Choice A, Adenovirus, is not the most common cause of bronchiolitis in infants. Choice B, Influenza virus, may cause respiratory infections but is not the primary cause of bronchiolitis. Choice D, Parainfluenza virus, can cause croup and other upper respiratory infections but is not the main cause of bronchiolitis in infants.
