1. Which physiological acid-base balance complication would be most important for the nurse to assess in a patient with diarrhea?

• A. High serum pH
• B. Normal serum pH
• C. Metabolic alkalosis
• D. Metabolic acidosis

Correct answer: D

Rationale: The correct answer is metabolic acidosis. Diarrhea can lead to the loss of bicarbonate, causing an imbalance in the acid-base status of the body, specifically resulting in metabolic acidosis. High serum pH (choice A) is incorrect as diarrhea-induced bicarbonate loss would lower pH, not increase it. Normal serum pH (choice B) is not the best answer as diarrhea can disrupt the acid-base balance. Metabolic alkalosis (choice C) is an alkaline state, which is less likely to be caused by diarrhea.

2. Which family theory explains how families react to stressful events and suggests factors that promote adaptation to these events?

• A. Interactional theory
• B. Family stress theory
• C. Erikson's psychosocial theory
• D. Developmental systems theory

Correct answer: B

Rationale: Family stress theory explains how families respond to stress and identifies factors that help families adapt to and manage stressful events effectively.

3. Frequent urine tests for specific gravity are required on a 6-month-old infant. What method is the most appropriate way to collect small amounts of urine for these tests?

• A. Apply a urine collection bag to the perineal area.
• B. Tape a small medicine cup inside of the diaper.
• C. Aspirate urine from cotton balls inside the diaper with a syringe without a needle.
• D. Use a syringe without a needle to aspirate urine from a superabsorbent disposable diaper.

Correct answer: C

Rationale: Aspirating urine from cotton balls inside the diaper is a minimally invasive method and effective for collecting small amounts of urine. Using a collection bag can be more cumbersome, and other methods are not as effective for this age.

4. Which is described as an elevated, circumscribed skin lesion that is less than 1 cm in diameter and filled with serous fluid?

• A. Cyst
• B. Papule
• C. Pustule
• D. Vesicle

Correct answer: D

Rationale: A vesicle is an elevated, circumscribed lesion filled with serous fluid, typically less than 1 cm in diameter.

5. 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.
