1. Phenytoin is an antiarrhythmic and anticonvulsant that has an unlabeled use for:
- A. Headaches
- B. Cold remedy
- C. Neuropathic pain
- D. Antianxiety
Correct answer: C
Rationale: Phenytoin, an antiarrhythmic and anticonvulsant medication, is also used off-label for treating neuropathic pain. While its primary indications are for managing heart rhythm disorders and seizures, it has shown efficacy in managing neuropathic pain, expanding its clinical utility. Choices A, B, and D are incorrect as phenytoin is not commonly used for headaches, cold remedies, or antianxiety purposes.
2. A client has a new prescription for Hydralazine. Which of the following adverse effects should the nurse instruct the client to monitor?
- A. Tachycardia
- B. Hyperglycemia
- C. Hyponatremia
- D. Constipation
Correct answer: A
Rationale: Corrected Rationale: Hydralazine is a vasodilator that can cause reflex tachycardia as an adverse effect. The client should monitor their pulse and report any significant increases, as tachycardia can indicate a severe adverse reaction to the medication. Choice B, Hyperglycemia, is not a common adverse effect of Hydralazine. Choice C, Hyponatremia, and Choice D, Constipation, are also not typically associated with Hydralazine use. Therefore, the correct answer is A: Tachycardia.
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. Which of the following drugs is associated with Stevens-Johnson syndrome?
- A. Valproic acid
- B. Quinidine
- C. Isoniazid
- D. Ethosuximide
Correct answer: D
Rationale: Stevens-Johnson syndrome is a severe skin reaction that can be associated with Ethosuximide.
5. A patient is receiving education about a new prescription for Omeprazole to manage heartburn. What information should the nurse include in the teaching?
- A. Take this medication at bedtime.
- B. This medication decreases the production of gastric acid.
- C. Take this medication 2 hours after eating.
- D. This medication can cause hyperkalemia.
Correct answer: B
Rationale: The correct information to include when teaching a patient about Omeprazole is that it decreases the production of gastric acid. Omeprazole works by inhibiting the proton pump in the stomach lining, thereby reducing acid secretion. This mechanism helps in managing heartburn symptoms effectively. Choice A is incorrect because Omeprazole is usually taken before a meal. Choice C is incorrect as Omeprazole is typically taken before meals, not after. Choice D is incorrect because hyperkalemia is not a common side effect of Omeprazole.
