1. The healthcare provider prescribes Amoxicillin 500mg PO every 8hrs for a child who weighs 22 pounds. The available suspension is labeled Amoxicillin Suspension 250mg/5ml. The recommended maximum dose is 50mg/kg/24hr. How many mL should the nurse administer in a single dose based on the child’s weight?
- A. 10mL
- B. 15mL
- C. 7.5mL
- D. 5mL
Correct answer: A
Rationale: To calculate the dose for the child weighing 22 pounds, first convert the weight to kg: 22 lbs ÷ 2.2 = 10 kg. The maximum dose based on weight would be 10 kg × 50 mg/kg/24hr = 500 mg/24hr. Since the medication is prescribed every 8 hours, the dose for each administration would be 500 mg ÷ 3 doses = 166.67 mg. As the available suspension is 250mg/5ml, the nurse should administer 166.67 mg ÷ 250 mg/mL = 0.67 mL per dose. However, since it's not practical to administer a fraction of a milliliter, the nurse should round up to the nearest appropriate dose, which is 10mL.
2. A 34-week primigravida woman with preeclampsia is receiving Lactated Ringer’s 500ml with magnesium sulfate 20 grams at the rate of 3g/hr. How many ml/hr should the nurse program the infusion pump?
- A. 75ml/hr
- B. 100ml/hr
- C. 50ml/hr
- D. 25ml/hr
Correct answer: A
Rationale: To calculate the infusion rate, divide the total quantity to be infused (500ml) by the total time (1 hour) which equals 500ml/hr. Since the magnesium sulfate is being given at 3g/hr, and 1g of magnesium sulfate is in 5ml of solution, the rate will be 3g/hr x 5ml/g = 15ml/hr. Therefore, the total infusion rate should be 500ml/hr + 15ml/hr = 515ml/hr. Hence, the nurse should program the infusion pump to deliver 75ml/hr (515ml/hr total - 500ml/hr Lactated Ringer's rate). This choice is correct because it accounts for both the Lactated Ringer's and magnesium sulfate rates. Choice B, 100ml/hr, is incorrect as it does not consider the additional magnesium sulfate infusion rate. Choice C, 50ml/hr, is incorrect because it does not account for the magnesium sulfate infusion. Choice D, 25ml/hr, is incorrect as it is too low and does not consider the magnesium sulfate being infused concurrently.
3. After a full-term vaginal delivery, a postpartum client's white blood cell count is 15,000/mm3. What action should the nurse take first?
- A. Check the differential, as the WBC count can be normal for this client.
- B. Assess the client's temperature, pulse, and respirations every 4 hours.
- C. Notify the healthcare provider, as this finding may indicate infection.
- D. Assess the client's perineal area for signs of a perineal hematoma.
Correct answer: A
Rationale: In postpartum clients, a white blood cell count of 15,000/mm3 can be within normal limits due to physiological changes that occur after childbirth. Checking the differential count would provide a more detailed analysis of the specific types of white blood cells present, helping to differentiate between normal postpartum changes and potential infection. This action allows the nurse to gather more information before escalating the situation to the healthcare provider or initiating other assessments. Assessing vital signs and the perineal area are important aspects of postpartum care but may not be the priority in this scenario where the white blood cell count can be influenced by normal physiological changes.
4. The nurse is caring for a 5-year-old child with Reye’s syndrome. Which goal of treatment most clearly relates to caring for this child?
- A. Reduce cerebral edema and lower intracranial pressure
- B. Avert hypotension and septic shock
- C. Prevent cardiac arrhythmias and heart failure
- D. Promote kidney perfusion and normal blood pressure
Correct answer: A
Rationale: Reducing cerebral edema and lowering intracranial pressure is the primary goal of treatment for Reye’s syndrome.
5. A full-term, 24-hour-old infant in the nursery regurgitates and suddenly turns cyanotic. What should the nurse do first?
- A. Suction the oral and nasal passages.
- B. Give oxygen by positive pressure.
- C. Stimulate the infant to cry.
- D. Turn the infant onto the right side.
Correct answer: A
Rationale: In a situation where an infant regurgitates and turns cyanotic, the priority action should be to clear any potential airway obstruction. Suctioning the oral and nasal passages is crucial to ensure the infant's airway is clear and allow for proper breathing. This intervention takes precedence over providing oxygen, stimulating the infant to cry, or repositioning the infant.
