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. The nurse is discussing development and play activities with the parent of a 2-month-old boy. Which statement by the parent would indicate a correct understanding of the teaching?

• A. I can give my baby a ball of yarn to pull apart or different textured fabrics to feel
• B. I can use a music box and soft mobiles as appropriate play activities for my baby
• C. I should introduce a cup and spoon or push-pull toys for my baby at this age
• D. I do not have to worry about appropriate play activities at this age

Correct answer: B

Rationale: At 2 months, infants are most stimulated by visual and auditory activities, such as a music box or soft mobiles. These activities help in sensory development and are appropriate for this age.

3. What physiologic state(s) produces the clinical manifestations of nervous system stimulation and excitement, such as overexcitability, nervousness, and tetany?

• A. Metabolic acidosis
• B. Respiratory alkalosis
• C. Metabolic and respiratory acidosis
• D. Metabolic and respiratory alkalosis

Correct answer: D

Rationale: Both metabolic and respiratory alkalosis can cause overexcitability and nervous system stimulation due to a decrease in ionized calcium levels, which can cause symptoms such as tetany and paresthesias. Acidosis typically has the opposite effect, leading to depression of the nervous system.

4. A mother brings 6-month-old Eric to the clinic for a well-baby checkup. She comments, "I want to go back to work, but I don't want Eric to suffer because I'll have less time with him." Which is the nurse's most appropriate answer?

• A. "I'm sure he'll be fine if you get a good babysitter."
• B. "You will need to stay home until Eric starts school."
• C. "Let's talk about the childcare options that will be best for Eric."
• D. "You should go back to work so Eric will get used to being with others."

Correct answer: C

Rationale: The best approach is to discuss childcare options that would suit Eric's needs, allowing the mother to make an informed decision without guilt or pressure.

5. 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.
