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. The healthcare provider prescribes oxytocin 2 milliunits/minute to induce labor for a client at 41-weeks gestation. The nurse initiates an infusion of Ringer’s Lactate solution 1000 mL with oxytocin 10 units. How many mL/hour should the nurse program the infusion pump?
- A. 12 mL/hour
- B. 2 mL/hour
- C. 22 mL/hour
- D. 42 mL/hour
Correct answer: A
Rationale: To calculate the infusion rate in mL/hour, first, convert 2 milliunits/minute to milliunits/hour by multiplying by 60 to get 120 milliunits/hour. Then, calculate the mL/hour using the formula: milliunits/hour (120) × total volume (1000 mL) ÷ units in IV solution (10 units) = 1200 mL/hour. Therefore, the nurse should program the infusion pump to deliver 12 mL/hour to provide the prescribed dose of oxytocin. Choice B is incorrect as it does not reflect the correct calculation. Choice C is incorrect as it is not derived from the correct formula. Choice D is incorrect as it is not the result of the accurate calculation based on the provided information.
3. The LPN/LVN assesses a client admitted to the labor and delivery unit and obtains the following data: dark red vaginal bleeding, uterus slightly tense between contractions, BP 110/68, FHR 110 beats/minute, cervix 1 cm dilated and uneffaced. Based on these assessment findings, what intervention should the nurse implement?
- A. Insert an internal fetal monitor.
- B. Assess for cervical changes q1h.
- C. Monitor bleeding from IV sites.
- D. Perform Leopold's maneuvers.
Correct answer: C
Rationale: Monitoring for bleeding from IV sites is the priority intervention in this situation. The dark red vaginal bleeding, uterine tension, and other assessment findings suggest a potential placental abruption. Monitoring bleeding from IV sites can help detect coagulopathy, which may be associated with placental abruption. Options A, B, and D are not the most appropriate interventions in this scenario. Inserting an internal fetal monitor, assessing for cervical changes, and performing Leopold's maneuvers are not the priority actions when dark red vaginal bleeding and uterine tension are present, indicating a potential emergency situation.
4. A client at 28 weeks gestation calls the antepartum clinic and reports experiencing a small amount of bright red vaginal bleeding without uterine contractions or abdominal pain. What instruction should the LPN/LVN provide?
- A. Come to the clinic today for an ultrasound.
- B. Go immediately to the emergency room.
- C. Lie on your left side for about one hour and see if the bleeding stops.
- D. Bring a urine specimen to the lab tomorrow to determine if you have a urinary tract infection.
Correct answer: A
Rationale: Bright red vaginal bleeding without pain could indicate placental issues such as previa. An ultrasound is necessary to evaluate the cause. It is important to rule out potential serious conditions like placental previa, which can lead to further complications for both the mother and the fetus. Therefore, prompt evaluation through an ultrasound at the clinic is essential for appropriate management and ensuring the well-being of the client and her baby.
5. A 4-year-old boy presents with a rash and is diagnosed with varicella (chickenpox). What is the most appropriate intervention to manage this condition?
- A. Administer oral acyclovir.
- B. Apply calamine lotion to soothe itching.
- C. Encourage scratching to relieve itching.
- D. Encourage bed rest to avoid spreading the rash.
Correct answer: B
Rationale: The most appropriate intervention for managing varicella (chickenpox) in a 4-year-old child is to apply calamine lotion to soothe itching. Calamine lotion helps alleviate the itching associated with the chickenpox rash, providing relief to the child. It is important to discourage scratching to prevent complications such as scarring or secondary bacterial infections. Encouraging bed rest can be beneficial for comfort but is not the primary intervention to manage chickenpox.
