Nursing Elites

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 6-year-old child is diagnosed with rheumatic fever and demonstrates associated chorea (sudden aimless movements of the arms and legs). Which information should the nurse provide to the parents?

• A. Muscle tension decreases with fine motor skill projects, so these activities should be encouraged.
• B. The chorea or movements are temporary and will eventually disappear.
• C. Permanent lifestyle changes are not needed to promote safety in the home.
• D. Consistent discipline is not directly related to controlling the movements.

Correct answer: B

Rationale: Chorea, or sudden aimless movements associated with rheumatic fever, is temporary in nature and will eventually disappear on its own. It is important for the nurse to reassure the parents that these movements are part of the condition and typically resolve over time without the need for permanent lifestyle changes or strict discipline. Providing accurate information and reassurance to the parents can help alleviate concerns and promote understanding of the condition's course. Choices A, C, and D are incorrect because muscle tension, permanent lifestyle changes, and consistent discipline are not directly related to the resolution of chorea in rheumatic fever.

3. Using Nägele's rule, what is the estimated date of delivery for a pregnant client who reports that the first day of her last menstrual period was August 2, 2006?

• A. April 25, 2007.
• B. May 9, 2007.
• C. May 29, 2007.
• D. June 2, 2007.

Correct answer: B

Rationale: Nägele's rule is used to estimate the date of delivery. It involves adding 7 days to the first day of the last menstrual period (August 2), which gives August 9. Then, subtracting 3 months from August 9, we arrive at May 9 of the following year as the estimated date of delivery. This makes choice B, 'May 9, 2007,' the correct answer. Choices A, C, and D are incorrect as they do not follow the correct calculation based on Nägele's rule.

4. A laboring client’s membranes rupture spontaneously. The nurse notices that the amniotic fluid is greenish-brown. What intervention should the nurse implement first?

• A. Turn the client to her left side
• B. Contact the healthcare provider
• C. Assess the fetal heart rate
• D. Check the cervical dilation

Correct answer: C

Rationale: The correct answer is to assess the fetal heart rate. When amniotic fluid is greenish-brown, it may indicate the presence of meconium, which can be concerning as it may lead to fetal distress. Assessing the fetal heart rate will help determine the well-being of the fetus and guide further actions to ensure the safety of both the mother and the baby.

5. 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.
