Nursing Elites

1. A healthcare professional is preparing to administer heparin 15,000 units subcutaneously every 12 hours. The available heparin injection is 20,000 units/mL. How many milliliters should the healthcare professional administer per dose?

• A. 0.8 mL
• B. 0.75 mL
• C. 0.5 mL
• D. 1 mL

Correct answer: A

Rationale: To calculate the volume to administer, use the formula: Desired dose / Concentration = Volume to administer. In this case, (15,000 units / 20,000 units/mL) = 0.75 mL. Since the volume needs to be rounded up to the nearest tenth, the correct answer is 0.8 mL. Choice B (0.75 mL) is incorrect because it does not account for rounding up the volume. Choices C (0.5 mL) and D (1 mL) are incorrect as they do not reflect the precise calculation based on the given concentration and desired dose.

2. A client is prescribed Digoxin. Which of the following findings should the nurse monitor as a sign of potential toxicity?

• A. Bradycardia
• B. Hypertension
• C. Hyperglycemia
• D. Hypocalcemia

Correct answer: A

Rationale: Bradycardia is a common sign of Digoxin toxicity. Digoxin can lead to toxicity, which can manifest as various signs and symptoms, including bradycardia. Monitoring the client's heart rate closely is crucial to detect and manage potential toxicity early. Hypertension, hyperglycemia, and hypocalcemia are not typically associated with Digoxin toxicity; therefore, they are incorrect choices.

3. What does it mean when a medication has a half-life?

• A. It only lasts for 30 minutes after the medication is given
• B. How long it takes for half of the dose to be eliminated from the bloodstream
• C. It is the peak of how effective the medicine is
• D. Drug is greatly reduced before it reaches the systemic circulation

Correct answer: B

Rationale: When a medication has a half-life, it refers to the time it takes for half of the dose to be eliminated from the bloodstream. This parameter is crucial in understanding the duration of action and dosing intervals for medications in clinical practice. Choice A is incorrect as the half-life is not about how long the medication lasts but about elimination from the body. Choice C is incorrect because the half-life is not about the peak effectiveness of the medicine. Choice D is incorrect as it does not accurately define the concept of half-life.

4. A client has a new prescription for Nevirapine, an NNRTI. Which of the following statements should the nurse include in discharge teaching?

• A. Take this medication with food to increase absorption.
• B. Avoid alcohol while taking this medication.
• C. Take this medication at the same time every day.
• D. Take this medication on an empty stomach.

Correct answer: B

Rationale: The correct statement to include in discharge teaching about Nevirapine, an NNRTI, is to advise the client to avoid alcohol while taking this medication. Alcohol can interact with Nevirapine and lead to potential adverse effects or decreased effectiveness. Choice A is incorrect because Nevirapine should be taken without food or on an empty stomach for optimal absorption. Choice C is a general recommendation for most medications but not specifically for Nevirapine. Choice D is incorrect as Nevirapine should not be taken on an empty stomach.

5. When instructing a client with a new prescription for Timolol on how to insert eye drops, which area should the nurse instruct the client to press on to prevent systemic absorption of the medication?

• A. Bony orbit
• B. Nasolacrimal duct
• C. Conjunctival sac
• D. Outer canthus

Correct answer: B

Rationale: Pressing on the nasolacrimal duct, located near the inner corner of the eye, blocks the lacrimal punctum and prevents the medication from entering the systemic circulation. This technique helps to ensure the medication stays localized in the eye, enhancing its therapeutic effect while minimizing systemic side effects. Choices A, C, and D are incorrect. The bony orbit is the eye socket and not a site to press for preventing systemic absorption. The conjunctival sac is where eye drops are instilled, not pressed on. The outer canthus is also not the correct area to press to prevent systemic absorption.
