Nursing Elites

1. A child has a central venous access device for intravenous (IV) fluid administration. A blood sample is needed for a complete blood count, hemogram, and electrolytes. What is the appropriate procedure to implement for this blood sample?

• A. Perform a new venipuncture to obtain the blood sample.
• B. Interrupt the IV fluid and withdraw the blood sample needed.
• C. Withdraw a blood sample equal to the amount of fluid in the device, discard, and then withdraw the sample needed.
• D. Flush the line and central venous device with saline and then aspirate the required amount of blood for the sample.

Correct answer: C

Rationale: Withdrawing and discarding a sample equal to the amount of fluid in the device ensures that the blood drawn is not diluted by the IV fluids, providing accurate lab results.

2. Which information about hemophilia will the nurse include in the teaching plan for the parents of a child diagnosed with hemophilia?

• A. Autosomal dominant disorder in which the blood clotting factors are deficient.
• B. X-linked recessive inherited disorder in which blood clotting factors are deficient.
• C. X-linked recessive inherited disorder involving decreased platelets causing prolonged bleeding.
• D. Autosomal recessive disorder in which the blood clotting factors are deficient.

Correct answer: B

Rationale: The correct answer is B: Hemophilia is an X-linked recessive disorder, primarily affecting males and passed from mothers to sons. It involves a deficiency in clotting factors, leading to prolonged bleeding. Choice A is incorrect as hemophilia is not autosomal dominant. Choice C is incorrect as hemophilia does not involve platelets. Choice D is incorrect as hemophilia is not autosomal recessive.

3. 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.

4. The nurse is preparing a 9-year-old boy before obtaining a blood specimen by venipuncture. The child tells the nurse he does not want to lose his blood. What approach is best by the nurse?

• A. Explain that it will not be painful.
• B. Suggest to him that he not worry about losing just a little bit of blood.
• C. Discuss with him how his body is always in the process of making blood.
• D. Tell the child that he will not even need a Band-Aid afterward because it is a simple procedure.

Correct answer: C

Rationale: Discussing how the body continuously makes blood helps the child understand that losing a small amount is normal and not harmful. This educational approach also helps reduce anxiety by giving the child a sense of control over the situation.

5. The predominant characteristic of the intellectual development of a child aged 2 to 7 years is egocentricity. Which of the following best describes this concept?

• A. Selfishness
• B. Unable to see another’s point of view
• C. Able to put self in another’s place
• D. Prefers to play alone

Correct answer: B

Rationale: Egocentricity in children aged 2 to 7 years means they are unable to see things from another person's perspective. This characteristic is a normal part of their cognitive development during this stage. Choice A, 'Selfishness,' is not an accurate description as egocentricity is more about a limited ability to understand others' viewpoints rather than intentional selfishness. Choice C, 'Able to put self in another’s place,' is incorrect as egocentric children struggle to do this. Choice D, 'Prefers to play alone,' is not directly related to egocentricity but may be a behavior exhibited by some children for various reasons.
