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?

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 laboratory test would be most important for the nurse to assess when caring for a toddler suspected of having cystic fibrosis?

Correct answer: C

Rationale: The sweat chloride test is the primary diagnostic test for cystic fibrosis. Cystic fibrosis is characterized by abnormal transport of chloride and sodium across epithelial cell membranes, leading to increased chloride in sweat. This test is crucial for diagnosing cystic fibrosis in suspected cases. Liver enzymes (Choice A), serum calcium (Choice B), and urine creatinine (Choice D) are not specific tests for cystic fibrosis and would not provide the necessary information for diagnosis in this case.

3. Which is considered a block to effective communication?

Correct answer: B

Rationale: Using clichés is a communication block because it can come across as dismissive or insincere, hindering meaningful dialogue.

4. The nurse is conducting discharge teaching to an adolescent with a methicillin-resistant Staphylococcus aureus (MRSA) infection. What should the nurse include in the instructions?

Correct answer: B

Rationale: Avoiding sharing of towels and washcloths, using bleach when laundering, and taking daily baths with antibacterial soap are critical to prevent the spread of MRSA. Cold water is not effective for laundering in these cases.

5. The nurse is caring for a child after a cleft palate repair who is on a clear liquid diet. Which feeding device should the nurse use to deliver the clear liquid diet?

Correct answer: D

Rationale: An open cup is recommended for feeding after cleft palate repair to prevent injury to the surgical site and avoid creating negative pressure, which could disrupt the repair.
