Nursing Elites

1. 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.

2. A nurse is preparing to administer heparin 8,000 units subcutaneously every eight hours. The amount available is heparin injection 10,000 units/mL. How many milliliters should the nurse administer per dose? (Round the answer to the nearest tenth)

• A. 0.8 mL
• B. 0.9 mL
• C. 10.0 mL
• D. 98.0 mL

Correct answer: A

Rationale: To determine the volume of heparin to administer per dose, divide the prescribed dose (8,000 units) by the concentration of heparin available (10,000 units/mL). 8000 units / 10000 units/mL = 0.8 mL. Therefore, the nurse should administer 0.8 mL per dose. Choice B, 0.9 mL, is incorrect as the correct calculation results in 0.8 mL. Choices C and D are significantly higher and incorrect, indicating an inaccurate calculation.

3. A nurse is providing teaching to a newly licensed nurse about caring for a client who has a prescription for gemfibrozil. The nurse should instruct the newly licensed nurse to monitor which of the following laboratory tests?

• A. Platelet count
• B. Electrolyte levels
• C. Thyroid function
• D. Liver function

Correct answer: D

Rationale: The correct answer is D: Liver function. Gemfibrozil can lead to hepatotoxicity, making it crucial to monitor liver function tests. Monitoring platelet count (choice A) is not specifically indicated for gemfibrozil. Electrolyte levels (choice B) and thyroid function (choice C) are not directly affected by gemfibrozil, so they are not the primary laboratory tests to monitor in this case.

4. A nurse is preparing a discharge teaching plan for a client who is to begin long-term oral prednisone for asthma. Which of the following instructions should the nurse include in the plan?

• A. Stop taking the medication if a rash occurs.
• B. Take the medication on an empty stomach to enhance absorption.
• C. Schedule the medication on alternate days to decrease adverse effects.
• D. Treat shortness of breath with an extra dose of the medication.

Correct answer: C

Rationale: When initiating long-term oral prednisone therapy for asthma, it is essential to schedule the medication on alternate days. This approach helps reduce the risk of adverse effects commonly associated with corticosteroid use. Choice A is incorrect because abrupt discontinuation of prednisone can lead to adrenal insufficiency. Choice B is incorrect as prednisone should be taken with food to minimize gastrointestinal side effects. Choice D is incorrect because using an extra dose of prednisone to treat shortness of breath is not appropriate and can lead to overdosing.

5. 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.
