Nursing Elites

1. A nurse is preparing to administer ampicillin 500 mg in 50 ml of dextrose 5% in water (D5W) to infuse over 15 min. The drop factor of the manual IV tubing is 10 gtt/mL. How many gtt/min should the nurse set the manual IV infusion to deliver? (Round to the nearest whole number)

• A. 33 gtt/min
• B. 66 gtt/min
• C. 10 gtt/min
• D. 14 gtt/min

Correct answer: A

Rationale: To calculate the IV flow rate, you multiply the drop factor (10 gtt/mL) by the volume to be infused per minute (50 mL / 15 min). This gives you 10 gtt/mL × 50 mL / 15 min = 33.33. Rounding to the nearest whole number, the nurse should set the manual IV infusion to deliver 33 gtt/min. Choice B (66 gtt/min) is incorrect as it is the result of doubling the correct answer. Choice C (10 gtt/min) is incorrect as it only considers the drop factor without accounting for the volume to be infused. Choice D (14 gtt/min) is incorrect as it miscalculates the infusion rate based on the given information.

2. A nurse is administering insulin glulisine 10 units subcutaneously at 0730 to an adolescent client who has type 1 diabetes mellitus. The nurse should anticipate the onset of action of the insulin at which of the following times?

• A. 0745
• B. 0700
• C. 0645
• D. 0457

Correct answer: A

Rationale: Insulin glulisine has a rapid onset of action, typically around 15 minutes. Therefore, the nurse should expect the onset around 0745. Choice A is correct as it aligns with the expected onset time. Choices B, C, and D are incorrect as they do not match the typical onset time of insulin glulisine.

3. A nurse is preparing to administer prochlorperazine 2.5 mg IV. Available is prochlorperazine injection 5 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth)

• A. 0.5 mL
• B. 0.005 mL
• C. 0.05 mL
• D. 5 mL

Correct answer: A

Rationale: To calculate the mL needed, set up a proportion: 5 mg / 1 mL = 2.5 mg / X mL. Cross multiply to find X: 5 * X = 2.5 * 1, X = 2.5 / 5 = 0.5 mL. Therefore, the nurse should administer 0.5 mL. Choice B, 0.005 mL, is incorrect as it doesn't match the calculated result. Choice C, 0.05 mL, is incorrect as it is ten times the correct value. Choice D, 5 mL, is incorrect as it represents the total volume of the entire vial, not the amount needed for the specific dose.

4. A nurse is providing teaching to a parent of a child who has asthma and a new prescription for a cromolyn sodium metered dose inhaler. Which of the following statements by the parent indicates the need for further teaching?

• A. I will give my child a dose as soon as wheezing starts.
• B. My child should rinse out his mouth after using the inhaler.
• C. My child should exhale completely before placing the inhaler in his mouth.
• D. If my child has difficulty breathing in the dose, a spacer can be used.

Correct answer: A

Rationale: The correct answer is A. Cromolyn sodium is a preventive medication and should not be used as a rescue inhaler when wheezing starts. This indicates a need for further teaching as the parent should understand that cromolyn sodium is not meant for immediate relief of symptoms. Choice B is correct as rinsing the mouth after using the inhaler helps reduce the risk of oral thrush, a common side effect. Choice C is correct as exhaling completely before using the inhaler helps ensure proper inhalation of the medication. Choice D is correct as a spacer can be used if the child has difficulty coordinating breathing with the inhaler, improving medication delivery.

5. A nurse is preparing to administer furosemide 4 mg/kg/day PO divided into 2 equal doses daily to a toddler who weighs 22 lb. How many mg should the nurse administer per dose? (Round the answer to the nearest whole number)

• A. 20 mg
• B. 15 mg
• C. 10 mg
• D. 30 mg

Correct answer: A

Rationale: To calculate the dosage per dose, first, convert the toddler's weight from pounds to kilograms: 22 lb / 2.2 = 10 kg. Then, multiply the weight by the dosage: 4 mg × 10 kg = 40 mg/day. Since this total daily dose is divided into 2 equal doses, the nurse should administer 20 mg per dose. Therefore, the correct answer is 20 mg. Choice B (15 mg) is incorrect because it does not account for the correct weight conversion and dosage calculation. Choice C (10 mg) is incorrect as it only considers the weight conversion but doesn't multiply it by the dosage. Choice D (30 mg) is incorrect as it miscalculates the dosage by not dividing the total daily dose into 2 equal parts.
