Nursing Elites

1. A client is receiving daily doses of Oprelvekin. Which of the following laboratory values should the nurse monitor to determine the effectiveness of this medication?

• A. Hemoglobin
• B. Absolute neutrophil count
• C. Platelet count
• D. Total white blood cell count

Correct answer: C

Rationale: The nurse should monitor the platelet count to determine the effectiveness of Oprelvekin. The expected outcome for this medication is a platelet count greater than 50,000/mm^3. Oprelvekin is a medication used to stimulate platelet production, making platelet count a crucial parameter to assess its effectiveness. Monitoring hemoglobin, absolute neutrophil count, or total white blood cell count is not specifically related to the action or effectiveness of Oprelvekin.

2. A client prescribed Warfarin is receiving discharge instructions from a nurse. Which of the following herbal supplements should the nurse instruct the client to avoid?

• A. St. John's wort
• B. Echinacea
• C. Garlic
• D. Ginseng

Correct answer: A

Rationale: St. John's wort can reduce the effectiveness of Warfarin by interacting with its metabolism pathways, potentially leading to decreased anticoagulant effects. Therefore, clients on Warfarin therapy should avoid St. John's wort. While echinacea, garlic, and ginseng are also herbal supplements that can interact with Warfarin, St. John's wort is particularly known for its significant impact on Warfarin metabolism. Echinacea may increase the risk of bleeding when taken with Warfarin, garlic may potentiate the anticoagulant effects of Warfarin, and ginseng may also increase the risk of bleeding. However, St. John's wort is the most crucial to avoid due to its significant impact on Warfarin metabolism.

3. A healthcare provider is reviewing the health record of a client who asks about using Propranolol to treat hypertension. The provider should recognize which of the following conditions is a contraindication for taking propranolol?

• A. Asthma
• B. Glaucoma
• C. Hypertension
• D. Tachycardia

Correct answer: A

Rationale: The correct answer is A: Asthma. Propranolol is a nonselective beta-adrenergic blocker that blocks both beta1 and beta2 receptors. Blockade of beta2 receptors in the lungs causes bronchoconstriction, making it contraindicated in clients with asthma. Using propranolol in asthma can exacerbate bronchoconstriction and potentially lead to respiratory distress or exacerbation of asthma symptoms. Choices B, C, and D are incorrect. Glaucoma, hypertension, and tachycardia are not contraindications for taking propranolol. In fact, propranolol is commonly used to treat hypertension and tachycardia.

4. A client is being discharged with a new prescription for Lisinopril. Which of the following instructions should be included by the healthcare provider?

• A. Avoid salt substitutes.
• B. Take this medication at bedtime.
• C. Increase your intake of potassium-rich foods.
• D. Take this medication with food.

Correct answer: A

Rationale: The correct answer is to instruct the client to avoid salt substitutes. Lisinopril, an ACE inhibitor, can lead to hyperkalemia, so it's essential to avoid salt substitutes that may contain potassium which can further elevate potassium levels. Choice B is incorrect because Lisinopril is typically taken once daily in the morning, not at bedtime. Choice C is incorrect as increasing potassium intake can exacerbate hyperkalemia when taking Lisinopril. Choice D is incorrect as Lisinopril is usually taken on an empty stomach, not with food.

5. 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.
