1. A client has a new prescription for Warfarin. The nurse should identify that the concurrent use of which of the following medications increases the client's risk of bleeding?
- A. Vitamin K
- B. Calcium carbonate
- C. Acetaminophen
- D. Ranitidine
Correct answer: C
Rationale: The correct answer is Acetaminophen. Acetaminophen, especially in high doses, can increase the risk of bleeding in clients taking warfarin. Warfarin works by inhibiting the clotting factors dependent on vitamin K, so Vitamin K intake should be consistent but not excessive. Calcium carbonate and ranitidine do not significantly increase the risk of bleeding when used concurrently with Warfarin.
2. A healthcare professional is preparing to administer a dose of Hydromorphone IV to a client. Which of the following actions should the healthcare professional take?
- A. Administer the medication over 5 minutes.
- B. Administer a dose of Naloxone prior to giving the Hydromorphone.
- C. Assess the client's blood pressure prior to administration.
- D. Inject the medication into the client's subcutaneous tissue.
Correct answer: A
Rationale: The correct action for the healthcare professional preparing to administer IV Hydromorphone to a client is to administer the medication over 5 minutes. This slow administration is crucial to reduce the risk of hypotension and respiratory depression. Administering the medication rapidly can lead to adverse effects. Option B, administering Naloxone prior to Hydromorphone, is incorrect because Naloxone is used as an antidote for opioid overdose, not as a routine pre-medication. Option C, assessing the client's blood pressure before administration, is important but not the immediate action to take to reduce adverse effects of Hydromorphone. Option D, injecting the medication into the client's subcutaneous tissue, is incorrect as Hydromorphone is meant for intravenous administration for rapid onset of action.
3. 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.
4. A client is taking Glipizide to treat Diabetes Mellitus. Which of the following laboratory tests should the nurse monitor to evaluate the effectiveness of this medication?
- A. Cholesterol level.
- B. Hematocrit.
- C. Blood glucose level.
- D. Calcium level.
Correct answer: C
Rationale: The correct answer is C: Blood glucose level. Monitoring the client's blood glucose level is crucial when taking Glipizide, a medication used to lower blood glucose levels in individuals with Diabetes Mellitus. By monitoring the blood glucose level, the nurse can evaluate the effectiveness of the medication in managing the client's condition. Choices A, B, and D are incorrect as they are not directly related to assessing the effectiveness of Glipizide in treating Diabetes Mellitus. Cholesterol level, hematocrit, and calcium level may be important for other aspects of the client's health but are not the primary indicators of Glipizide's effectiveness.
5. At what amount does Acetaminophen stop effectively controlling pain?
- A. Over 1,000 mg
- B. 750 mg
- C. Over 1,500 mg
- D. 150 mg
Correct answer: A
Rationale: Acetaminophen is known to lose its effectiveness in controlling pain beyond a dosage of 1,000 mg. Taking more than 1,000 mg will not provide additional pain relief but can increase the risk of adverse effects. Choice B (750 mg) is incorrect because this amount is within the typical recommended dose range for Acetaminophen. Choice C (Over 1,500 mg) is incorrect as it suggests a higher dose than the point at which Acetaminophen starts to lose its effectiveness. Choice D (150 mg) is too low a dose to effectively control pain for most adults.
