1. A child weighing 20 kg has a new prescription for cefoxitin at 80 mg/kg/day administered intravenously every 6 hours. How much cefoxitin should be administered with each dose?

• A. 400 mg
• B. 200 mg
• C. 1600 mg
• D. 100 mg

Correct answer: A

Rationale: To determine the amount of cefoxitin to be administered with each dose, first, calculate the total daily dose by multiplying the child's weight (20 kg) by the prescribed dose (80 mg/kg/day): 80 mg/kg/day × 20 kg = 1600 mg/day. Since the medication is administered every 6 hours (4 doses/day), divide the total daily dose by the number of doses: 1600 mg / 4 = 400 mg. Therefore, each dose should be 400 mg. Choice B (200 mg) is incorrect because it is half the calculated dose. Choice C (1600 mg) is incorrect as it represents the total daily dose, not the dose per administration. Choice D (100 mg) is incorrect as it is a quarter of the calculated dose.

2. A client has a prescription for a 24-hour urine collection. Which of the following actions should the nurse take?

• A. Discard the first voiding.
• B. Keep the urine in a single container on ice.
• C. Include the last voiding in the collection.
• D. Instruct the client to urinate into the toilet, stop midstream, and finish urinating into the specimen container.

Correct answer: A

Rationale: The correct action for the nurse to take when a client has a prescription for a 24-hour urine collection is to discard the first voiding. This initial voiding is typically not collected to allow for the accurate start of the 24-hour collection period. All subsequent urine voided within the specified time frame is then collected. Including the last voiding in the collection is important to ensure that the full 24-hour period is covered. It is essential to keep the urine cool by storing it in a single container on ice to prevent degradation of components. Instructing the client to stop midstream and finish urinating into the specimen container is not required for a 24-hour urine collection and is an unnecessary step.

3. When assessing the respiratory system for complications of immobility, what action should the nurse take?

• A. Inspect chest wall movements primarily during the expiratory cycle.
• B. Auscultate the entire lung region to assess lung sounds.
• C. Focus auscultation on the upper lung fields.
• D. Assess the patient at least every 4 hours.

Correct answer: B

Rationale: The correct action for the nurse when assessing the respiratory system for complications of immobility is to auscultate the entire lung region. This approach allows the nurse to identify any diminished breath sounds, crackles, or wheezes that may indicate respiratory issues. Inspecting chest wall movements primarily during the expiratory cycle (Choice A) may not provide a comprehensive assessment of lung sounds. Focusing auscultation on the upper lung fields (Choice C) may miss important findings in the lower lung fields. Assessing the patient at least every 4 hours (Choice D) is important for monitoring overall patient condition but does not specifically address the assessment of respiratory complications related to immobility.

4. A client with chronic kidney disease is being assessed. Which of the following laboratory values would be most concerning?

• A. Serum creatinine of 3.0 mg/dL
• B. Serum potassium of 6.5 mEq/L
• C. Blood urea nitrogen (BUN) of 45 mg/dL
• D. Hemoglobin of 10 g/dL

Correct answer: B

Rationale: In a client with chronic kidney disease, elevated serum potassium levels (hyperkalemia) are the most concerning finding. Hyperkalemia can lead to life-threatening cardiac dysrhythmias. Monitoring and managing serum potassium levels are crucial in patients with kidney disease to prevent severe complications. While elevated creatinine (Choice A) and BUN (Choice C) are indicative of impaired kidney function, hyperkalemia poses a more immediate threat to the client's health. Hemoglobin levels (Choice D) can be affected by chronic kidney disease but are not as acutely dangerous as severe hyperkalemia.

5. What finding signifies that children have attained the stage of concrete operations according to Piaget?

• A. Demonstrates exploration of the environment through sight and movement
• B. Thinks in mental images or word pictures
• C. Makes the moral judgment that 'stealing is wrong'
• D. Reasons that homework is time-consuming yet necessary

Correct answer: C

Rationale: The correct answer is C, 'Makes the moral judgment that 'stealing is wrong''. This finding signifies the attainment of the concrete operational stage according to Piaget. At this stage, children begin to understand rules and logic, including moral judgments. Choice A is incorrect because it does not specifically relate to concrete operational thinking. Choice B is incorrect as it refers more to the preoperational stage where children engage in symbolic thought. Choice D is also incorrect as it involves practical reasoning, which is not directly related to the concrete operational stage according to Piaget.
