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. The healthcare provider prescribes magnesium sulfate 6 grams intravenously (IV) to be infused over 20 minutes for a client with preterm labor. The IV bag contains magnesium sulfate 20 grams in dextrose 5% in water 500 mL. How many mL/hour should the nurse set the infusion pump?

• A. 150 mL/hour
• B. 250 mL/hour
• C. 50 mL/hour
• D. 275 mL/hour

Correct answer: A

Rationale: To calculate the infusion rate, first, determine the total volume to be infused (6 grams of magnesium sulfate) over a specific time frame (20 minutes). Then, calculate the concentration of magnesium sulfate in the IV bag to determine the mL/hour rate. The IV bag contains 20 grams of magnesium sulfate in 500 mL of solution, which means there are 4 grams of magnesium sulfate per 100 mL. Since 6 grams are required, the nurse should set the pump to deliver 150 mL/hour to infuse the prescribed dose over 20 minutes. Choice B, 250 mL/hour, is incorrect because it miscalculates the amount of magnesium sulfate infused per hour. Choice C, 50 mL/hour, is incorrect as it is too slow to deliver the required dose in the specified time frame. Choice D, 275 mL/hour, is incorrect as it overestimates the infusion rate and would deliver the dose too quickly.

3. Twenty minutes after a continuous epidural anesthetic is administered, a laboring client's blood pressure drops from 120/80 to 90/60. What action should the healthcare provider take?

• A. Notify the healthcare provider or anesthesiologist immediately.
• B. Continue to assess the blood pressure every 5 minutes.
• C. Place the woman in a lateral position.
• D. Turn off the continuous epidural.

Correct answer: C

Rationale: Placing the woman in a lateral position is the appropriate action to improve venous return and cardiac output, helping to stabilize the blood pressure. This position can alleviate pressure on the inferior vena cava, reducing the risk of hypotension associated with epidural anesthesia. Turning off the continuous epidural would not be the initial action as it may not be necessary and could lead to inadequate pain relief for the client. Notifying the healthcare provider or anesthesiologist immediately is premature and should be done after attempting non-invasive interventions. Continuing to assess the blood pressure every 5 minutes is important, but placing the woman in a lateral position should be the first intervention to address the hypotension.

4. A male infant with a 2-day history of fever and diarrhea is brought to the clinic by his mother, who tells the nurse that the child refuses to drink anything. The nurse determines that the child has a weak cry with no tears. Which intervention is most important to implement?

• A. Provide a bottle of electrolyte solution.
• B. Infuse normal saline intravenously.
• C. Administer an antipyretic rectally.
• D. Apply an external cooling blanket.

Correct answer: B

Rationale: Infusing normal saline intravenously is crucial to treat dehydration caused by fever and diarrhea. In this scenario, the infant's weak cry with no tears indicates severe dehydration, necessitating rapid fluid replacement via intravenous normal saline to restore fluid balance and prevent complications.

5. Albumin 25% IV is prescribed for a child with nephrotic syndrome. Which assessment finding indicates to the nurse that the medication is having the desired effect?

• A. Weight gain.
• B. Reduction of fever.
• C. Improved caloric intake.
• D. Reduction of edema.

Correct answer: D

Rationale: The correct answer is D: Reduction of edema. Albumin helps reduce edema by increasing oncotic pressure, drawing fluid back into the blood vessels. In nephrotic syndrome, there is an abnormal loss of protein in the urine, leading to decreased oncotic pressure and fluid shifting into the interstitial spaces, causing edema. Administering albumin helps restore the oncotic pressure, reducing edema, which is a desirable effect of the medication.
