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 is preparing to administer methylergonovine maleate (Methergine) to a postpartum client. Based on what assessment finding should the healthcare provider withhold the drug?
- A. Respiratory rate of 22 breaths/min
- B. A large amount of lochia rubra
- C. Blood pressure 149/90
- D. Positive Homan’s sign
Correct answer: C
Rationale: A blood pressure of 149/90 is an indication to withhold Methergine due to its potential to further increase blood pressure. Methergine is a medication that can cause vasoconstriction, leading to elevated blood pressure. In this case, administering Methergine could exacerbate the elevated blood pressure, posing a risk to the patient. Therefore, it is crucial to withhold the medication in the presence of hypertension to prevent adverse effects. The other options are not directly related to the administration of Methergine. A respiratory rate of 22 breaths/min is within the normal range. A large amount of lochia rubra may indicate normal postpartum bleeding. A positive Homan’s sign is associated with deep vein thrombosis, which is not a contraindication for administering Methergine.
3. A client at 32-weeks gestation is diagnosed with preeclampsia. Which assessment finding is most indicative of an impending convulsion?
- A. 3+ deep tendon reflexes and hyperreflexia.
- B. Periorbital edema, flashing lights, and aura.
- C. Epigastric pain in the third trimester.
- D. Recent decreased urinary output.
Correct answer: A
Rationale: In a client with preeclampsia, 3+ deep tendon reflexes and hyperreflexia are indicative of severe preeclampsia. These neurological signs suggest an increased risk for seizures, making option A the most indicative of an impending convulsion. Choices B, C, and D are not directly associated with an impending convulsion in a client with preeclampsia.
4. A 6-week-old infant diagnosed with pyloric stenosis has recently developed projectile vomiting. Which assessment finding indicates to the nurse that the infant is becoming dehydrated?
- A. Weak cry without tears.
- B. Bulging fontanel.
- C. Visible peristaltic wave.
- D. Palpable mass in the right upper quadrant.
Correct answer: A
Rationale: In infants, a weak cry without tears is a classic sign of dehydration. Tears are produced by the lacrimal glands, and reduced tear production is a result of dehydration. This assessment finding should alert the nurse to the infant's dehydration status, requiring prompt intervention to prevent further complications.
5. 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.
