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. When teaching a client with a new prescription for nitroglycerin patches, which of the following instructions should the nurse include?

• A. Apply the patch at the same time every day.
• B. Rotate the application site daily.
• C. Remove the patch for 12 hours each day.
• D. Cut the patch in half if needed.

Correct answer: B

Rationale: The correct instruction for a client with a new prescription for nitroglycerin patches is to rotate the application site daily. This is important to prevent skin irritation and ensure optimal absorption of the medication. Applying the patch at the same time every day (Choice A) is not necessary for nitroglycerin patches. Removing the patch for 12 hours each day (Choice C) would disrupt the continuous delivery of medication. Cutting the patch in half (Choice D) can alter the dose and is not recommended unless directed by a healthcare provider.

3. A client is receiving warfarin therapy. Which of the following findings should the nurse identify as an adverse effect of warfarin?

• A. Nausea
• B. Epistaxis
• C. Diarrhea
• D. Dyspepsia

Correct answer: B

Rationale: Epistaxis, or nosebleeds, can be an indication of excessive anticoagulation while on warfarin therapy. Warfarin is a blood thinner that helps prevent blood clots. Epistaxis can occur as a result of the blood-thinning effects of warfarin, leading to increased bleeding tendencies, including nosebleeds. Nausea, diarrhea, and dyspepsia are not typically associated with warfarin therapy; therefore, they are not the adverse effects the nurse should identify in a client receiving warfarin.

4. How is lithium typically administered?

• A. Intravenously
• B. Intramuscularly
• C. Orally
• D. Sublingually

Correct answer: C

Rationale: Lithium is typically administered orally to ensure proper absorption and distribution in the body. By taking lithium orally, it allows the medication to be absorbed through the gastrointestinal tract and distributed effectively. Intravenous and intramuscular routes are not commonly used for lithium administration as they can lead to rapid, unpredictable absorption and increase the risk of toxicity. Sublingual administration is also not the typical route for lithium, as it is usually taken orally for consistent and controlled absorption.

5. When caring for a client with a wound infection, which action should the nurse perform first in the plan of care?

• A. Administer antibiotic medication.
• B. Obtain a wound specimen for culture.
• C. Review WBC laboratory findings.
• D. Apply a dressing to the wound.

Correct answer: B

Rationale: The priority action when caring for a client with a wound infection is to obtain a wound specimen for culture before initiating antibiotic therapy. This step is crucial to identify the specific microorganism causing the infection, allowing for targeted antibiotic treatment. Reviewing WBC laboratory findings and applying a wound dressing are important steps, but obtaining a wound specimen for culture takes precedence as it guides appropriate antibiotic therapy by identifying the causative organism.
