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 healthcare professional is planning to administer IV Alteplase to a client who is demonstrating manifestations of a massive Pulmonary Embolism. Which of the following interventions should the healthcare professional plan to take?

• A. Administer IM Enoxaparin along with the Alteplase dose.
• B. Hold direct pressure on puncture sites for up to 30 min.
• C. Administer Aminocaproic acid IV prior to alteplase infusion.
• D. Prepare to administer Alteplase within 8 hr of manifestation onset.

Correct answer: B

Rationale: The correct intervention when administering IV Alteplase is to hold direct pressure on puncture sites for 10 to 30 minutes or until oozing of blood stops. This helps prevent bleeding complications associated with thrombolytic therapy. Administering IM Enoxaparin is not indicated with Alteplase, as it is an anticoagulant rather than a thrombolytic agent. Aminocaproic acid is not typically administered prior to alteplase infusion in the context of a massive Pulmonary Embolism. While timely administration of Alteplase is important, the specific timeframe within which it should be administered may vary based on the clinical situation, so a strict 8-hour window is not universally applicable.

3. What is an expected outcome for Lithium use in patients with bipolar disorder?

• A. Reduced risk of myocardial infarction
• B. Reduced risk of GI ulcers
• C. Decrease in respiratory distress
• D. Decreased incidence of acute manic episodes

Correct answer: D

Rationale: The correct answer is D: Decreased incidence of acute manic episodes. Lithium is commonly used to treat bipolar disorder by helping to stabilize mood and reduce the intensity and frequency of manic episodes. This leads to better overall management of the disorder. Choices A, B, and C are incorrect because lithium is not known to reduce the risk of myocardial infarction, GI ulcers, or respiratory distress in patients with bipolar disorder.

4. During a unit of whole blood transfusion, a client develops a cough, shortness of breath, elevated blood pressure, and distended neck veins. The healthcare professional should anticipate a prescription for which of the following medications?

• A. Epinephrine
• B. Lorazepam
• C. Furosemide
• D. Diphenhydramine

Correct answer: C

Rationale: In the scenario described, the client is exhibiting signs of fluid overload, which can occur during blood transfusion. Furosemide, a loop diuretic, is commonly prescribed in such situations to help relieve manifestations of circulatory overload by promoting diuresis and reducing fluid volume. Therefore, the correct choice is C - Furosemide. Epinephrine (Choice A) is not indicated for fluid overload but for severe allergic reactions. Lorazepam (Choice B) is a benzodiazepine used for anxiety or sedation, not for fluid overload. Diphenhydramine (Choice D) is an antihistamine often used for allergic reactions, not for fluid overload.

5. How can the nurse best explain the difference between angina and a myocardial infarction to a client presenting with severe chest pain?

• A. “Angina usually resolves with rest, and is rarely fatal, while a myocardial infarction necessitates immediate treatment and can be life-threatening.”
• B. “There is a clear distinction between the two. You will receive treatment based on the diagnosis of a myocardial infarction.”
• C. “Both conditions result from a clot obstructing the coronary arteries. Angina occurs with the blockage of a small vessel, whereas a myocardial infarction occurs with a blockage of a large vessel.”
• D. “Angina may not cause as intense chest pain, whereas a myocardial infarction always presents with severe chest pain.”

Correct answer: A

Rationale: When educating a client about the differences between angina and a myocardial infarction, it is crucial to emphasize key distinguishing factors. Angina typically improves with rest and is not usually life-threatening, whereas a myocardial infarction requires urgent intervention as it can be life-threatening. This explanation helps the client understand the urgency and severity associated with a myocardial infarction compared to angina.
