Nursing Elites

1. Where would nonpathologic cyanosis normally be present in the newborn shortly after birth?

• A. Feet and hands
• B. Bridge of nose
• C. Circumoral area
• D. Mucous membranes

Correct answer: A

Rationale: Nonpathologic cyanosis in newborns shortly after birth is typically present in the feet and hands, known as acrocyanosis. This is a normal finding due to the immature peripheral circulation in newborns. Cyanosis of the bridge of the nose, circumoral area, and mucous membranes indicates generalized cyanosis, which suggests a potential underlying distress or major abnormality. Therefore, choice A is correct as it describes the expected location for nonpathologic cyanosis in newborns, while choices B, C, and D represent areas associated with abnormal cyanosis.

2. What urine test result is considered abnormal?

• A. pH 4.0
• B. WBC 1 or 2 cells/ml
• C. Protein level absent
• D. Specific gravity 1.020

Correct answer: A

Rationale: A urine pH of 4.0 is abnormally low, indicating possible acidosis or other metabolic conditions. WBC count of 1-2 cells/ml, absence of protein, and a specific gravity of 1.020 are within normal limits.

3. Which sign is indicative of developmental dysplasia of the hip in infants?

• A. Ortolani sign
• B. Romberg sign
• C. Trendelenburg sign
• D. Gower's sign

Correct answer: A

Rationale: The Ortolani sign is a specific maneuver used during physical examination to detect hip instability or dislocation in infants. A positive Ortolani sign, where the hip is felt to slip back into the socket, is indicative of developmental dysplasia of the hip, a condition that can lead to long-term disability if not treated early. Romberg sign is used to assess sensory ataxia, Trendelenburg sign indicates weakness of the hip abductor muscles, and Gower's sign is seen in children with proximal muscle weakness climbing up their own body from a supine position due to conditions like muscular dystrophy.

4. The nurse is caring for an infant after a cleft lip repair. Which of these measures should be included in the plan of care?

• A. Position prone
• B. Provide fluids from a cup
• C. Position supine
• D. Avoid elbow restraints

Correct answer: C

Rationale: The correct measure that should be included in the plan of care for an infant after a cleft lip repair is to position the infant supine. Placing the infant in a supine position helps protect the surgical site from injury and promotes proper healing. Choice A, 'Position prone,' is incorrect as placing the infant prone can put pressure on the surgical site and hinder healing. Choice B, 'Provide fluids from a cup,' is not directly related to the surgical care of a cleft lip repair. Choice D, 'Avoid elbow restraints,' is not specific to the postoperative care of a cleft lip repair.

5. When should a child receive the first dose of the hepatitis B virus (HBV) vaccine if the mother is hepatitis B surface antigen (HBsAg) negative?

• A. 2 months of age, before hospital discharge.
• B. Birth before discharge from the hospital.
• C. 6 months of age, at the third well-child visit.
• D. No time (this vaccine is not currently recommended).

Correct answer: B

Rationale: If the mother is HBsAg negative, it is recommended that the child receives the first dose of the hepatitis B vaccine at birth before discharge from the hospital. This is to provide early protection against the hepatitis B virus. The second dose of the vaccine is typically given at the first well-child visit, and the third dose is usually administered at a later date. The Advisory Committee on Immunization Practices of the Centers for Disease Control and Prevention and the Committee on Infectious Diseases of the American Academy of Pediatrics govern the recommendations for immunization, including the hepatitis B virus vaccine. Choice A is incorrect as the first dose should ideally be given at birth. Choice C is incorrect as waiting until 6 months of age may leave the child vulnerable to infection during the early months of life. Choice D is incorrect as the hepatitis B vaccine is recommended for all newborns, especially if the mother is HBsAg negative, to prevent transmission of the virus.
