1. A healthcare professional is preparing to administer heparin 15,000 units subcutaneously every 12 hr. The amount available is heparin injection 20,000 units/mL. How many mL 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, which is rounded up to 0.8 mL. Therefore, the healthcare professional should administer 0.8 mL per dose of heparin. Choice B (0.75 mL) is incorrect as it is the exact calculated volume but needs to be rounded up. Choices C (0.5 mL) and D (1 mL) are incorrect as they do not reflect the correct calculated volume for the desired dose of heparin.
2. When preparing to administer IV Acyclovir for Herpes Zoster, what action should the nurse take?
- A. Infuse the medication over 1 hour.
- B. Monitor the client's blood pressure every 15 minutes during infusion.
- C. Administer a stool softener.
- D. Monitor the client's blood glucose level every 4 hours during infusion.
Correct answer: A
Rationale: The correct action for the nurse is to infuse IV Acyclovir over at least 1 hour to prevent nephrotoxicity. Rapid infusion can lead to adverse effects, so a slow infusion rate is crucial for patient safety. Monitoring blood pressure, administering a stool softener, or monitoring blood glucose levels are not directly related to the administration of IV Acyclovir for Herpes Zoster.
3. A client has a new prescription for Metoprolol. Which of the following instructions should the nurse include?
- A. Take this medication with food.
- B. Monitor for signs of hyperglycemia.
- C. Avoid sudden discontinuation of the medication.
- D. Increase your intake of potassium-rich foods.
Correct answer: C
Rationale: The correct answer is to instruct the client to avoid sudden discontinuation of Metoprolol. Metoprolol is a beta-blocker that should be tapered off gradually to prevent rebound hypertension and other cardiac issues. Abruptly stopping Metoprolol can lead to serious complications, so it is essential for the client to follow the healthcare provider's guidance on discontinuation. Choice A is incorrect because Metoprolol can be taken with or without food. Choice B is incorrect as Metoprolol is not typically associated with causing hyperglycemia. Choice D is also incorrect as there is no need to increase potassium-rich foods specifically due to taking Metoprolol.
4. A client with chronic myeloid leukemia is receiving hydroxyurea. Which of the following findings should the nurse monitor?
- A. Hyperkalemia
- B. Hypertension
- C. Neutropenia
- D. Tinnitus
Correct answer: C
Rationale: The nurse should monitor the client for neutropenia when receiving hydroxyurea, as it is a common adverse effect caused by bone marrow suppression. Neutropenia increases the risk of infections, making it crucial for the nurse to closely monitor the client's white blood cell count.
5. A client has a new prescription for Warfarin. Which of the following statements by the client indicates a need for further teaching?
- A. I will avoid eating large amounts of green leafy vegetables.
- B. I will take my medication at the same time every day.
- C. I will increase my intake of foods high in potassium.
- D. I will report any signs of bleeding to my provider.
Correct answer: C
Rationale: The correct answer is C because Warfarin interacts with vitamin K, not potassium. Therefore, the client needs to be cautious with foods high in vitamin K, such as green leafy vegetables, rather than foods high in potassium. Choices A, B, and D are correct statements regarding Warfarin therapy and do not indicate a need for further teaching.
