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 4-week-old premature infant has been receiving epoetin alfa (Epogen) for the last three weeks. Which assessment finding indicates to the healthcare provider that the drug is effective?
- A. Slowly increasing urinary output over the last week.
- B. Respiratory rate changes from the 40s to the 60s.
- C. Changes in apical heart rate from the 180s to the 140s.
- D. Change in indirect bilirubin from 12 mg/dl to 8 mg/dl.
Correct answer: C
Rationale: The correct answer is C. Epoetin alfa stimulates erythropoiesis, leading to an increase in red blood cell production and improving oxygen-carrying capacity. As the oxygenation status improves, there is a reduction in heart rate. Therefore, changes in apical heart rate from the 180s to the 140s indicate that the drug is effective. Choices A, B, and D are incorrect because they do not directly reflect the expected outcome of epoetin alfa therapy. Increasing urinary output, changes in respiratory rate, and decreasing bilirubin levels are not primary indicators of the drug's effectiveness in this context.
3. The healthcare provider is preparing to administer magnesium sulfate to a laboring client whose blood pressure has increased from 110/60 mmHg to 140/90 mmHg. Which action is the highest priority?
- A. Provide a quiet environment with subdued lighting.
- B. Have calcium gluconate immediately available.
- C. Assess deep tendon reflexes (DTRs) every 4 hours.
- D. Insert a Foley catheter with a urimeter to monitor hourly output.
Correct answer: B
Rationale: Having calcium gluconate readily available is crucial when administering magnesium sulfate, as it serves as the antidote in case of magnesium toxicity. Magnesium sulfate can lead to respiratory depression and cardiac arrest in cases of overdose or toxicity, making the prompt availability of calcium gluconate essential for immediate administration to counteract these effects. Providing a quiet environment with subdued lighting may be beneficial for the client's comfort but is not the highest priority in this situation. Assessing deep tendon reflexes every 4 hours is important when administering magnesium sulfate, but it is not the highest priority compared to having calcium gluconate available. Inserting a Foley catheter with a urimeter to monitor hourly output is not the highest priority when preparing to administer magnesium sulfate in this scenario.
4. A 36-week primigravida is admitted to labor and delivery with severe abdominal pain and bright red vaginal bleeding. Her abdomen is rigid and tender to touch. The fetal heart rate (FHR) is 90 beats/minute, and the maternal heart rate is 120 beats/minute. What action should the nurse implement first?
- A. Alert the neonatal team and prepare for neonatal resuscitation
- B. Notify the healthcare provider from the client’s bedside
- C. Obtain written consent for an emergency cesarean section
- D. Draw a blood sample for stat hemoglobin and hematocrit
Correct answer: B
Rationale: In this scenario, the priority action for the nurse is to notify the healthcare provider from the client's bedside. The clinical presentation of severe abdominal pain, bright red vaginal bleeding, rigid and tender abdomen, along with fetal bradycardia (FHR 90 bpm) and maternal tachycardia (120 bpm) indicates an urgent need for medical intervention. Notifying the healthcare provider promptly allows for immediate assessment and decision-making to address the critical condition and ensure timely and appropriate management for both the mother and fetus.
5. The client delivered hours ago and has a boggy uterus displaced above and to the right of the umbilicus. What action should the nurse take?
- A. Inspect the perineal pad.
- B. Encourage voiding.
- C. Monitor vital signs.
- D. Notify the healthcare provider.
Correct answer: B
Rationale: A boggy uterus that is displaced above and to the right of the umbilicus may indicate a full bladder, which can impede uterine contraction and lead to hemorrhage. Encouraging the client to void helps relieve pressure on the uterus, promoting better contraction and preventing postpartum hemorrhage.
