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 a client is discharged with nitroglycerin (Nitrostat), what should the nurse include in client education?
- A. “Your chest pain should go away with one tablet.”
- B. “If your chest pain doesn’t go away after three tablets, call 911; you might be having a heart attack.”
- C. “If your chest pain doesn’t go away with one tablet, you can repeat the dose as many times as you need to.”
- D. “Be sure to call 911 before you take any tablets.”
Correct answer: B
Rationale: The correct answer instructs the client on the appropriate use of nitroglycerin. Nitroglycerin is used to relieve chest pain or angina. If the chest pain does not subside after taking one tablet, the client should take a maximum of three tablets at 5-minute intervals. If the pain persists after three tablets, it could indicate a heart attack, and emergency medical help should be sought. This education is crucial to ensure the client knows when to seek immediate medical attention.
3. A nurse is providing discharge instructions to a client who has a new prescription for a Fentanyl transdermal patch. Which of the following instructions should the nurse include?
- A. Apply the patch to a hairy area.
- B. Change the patch every 24 hours.
- C. Avoid exposure to heat sources.
- D. Cut the patch to adjust the dosage.
Correct answer: C
Rationale: The correct instruction that the nurse should include when providing discharge instructions for a client with a Fentanyl transdermal patch is to avoid exposure to heat sources. Heat can increase the absorption of the medication, leading to a risk of overdose. Choice A is incorrect because the patch should be applied to a clean, non-hairy area. Choice B is incorrect as the Fentanyl patch is usually changed every 72 hours, not every 24 hours. Choice D is incorrect as the patch should never be cut to adjust the dosage.
4. A client has a new prescription for Verapamil. Which of the following instructions should the nurse include?
- A. Increase your intake of high-fiber foods.
- B. Take the medication with grapefruit juice.
- C. Expect to feel drowsy or lightheaded.
- D. Avoid dairy products while taking this medication.
Correct answer: A
Rationale: The correct instruction to include when a client is prescribed Verapamil is to increase their intake of high-fiber foods. Verapamil can cause constipation as a side effect, and increasing fiber intake can help prevent constipation. High-fiber foods promote bowel regularity and can counteract the constipating effects of Verapamil. Choices B, C, and D are incorrect because taking Verapamil with grapefruit juice can lead to adverse reactions, drowsiness or lightheadedness is not a typical side effect of Verapamil, and there is no need to avoid dairy products specifically while taking this medication.
5. A healthcare professional is reviewing the laboratory results of a client who is taking Lithium for Bipolar Disorder. Which of the following findings should the healthcare professional report to the provider immediately?
- A. Lithium level of 1.0 mEq/L
- B. Potassium level of 3.5 mEq/L
- C. Sodium level of 140 mEq/L
- D. Creatinine level of 1.0 mg/dL
Correct answer: D
Rationale: A creatinine level of 1.0 mg/dL should be reported to the provider immediately. While a lithium level of 1.0 mEq/L falls within the therapeutic range, a creatinine level of 1.0 mg/dL could suggest early signs of kidney dysfunction, especially concerning in a client on long-term lithium therapy. It is crucial to monitor kidney function closely because lithium can be nephrotoxic over time. Elevated creatinine levels may indicate impaired kidney function and should prompt immediate reporting to the healthcare provider. Potassium and sodium levels within normal range are not immediate concerns when compared to potential kidney issues.
