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. A client received IV Verapamil to treat supraventricular tachycardia (SVT). The client's pulse rate is now 98/min, and blood pressure is 74/44 mm Hg. The nurse should anticipate a prescription for which of the following IV medications?
- A. Calcium gluconate
- B. Sodium bicarbonate
- C. Potassium chloride
- D. Magnesium sulfate
Correct answer: A
Rationale: In this situation, where the client's blood pressure is significantly lowered due to Verapamil administration, the nurse should anticipate a prescription for Calcium gluconate. Calcium gluconate is used to reverse severe hypotension caused by Verapamil. It should be given slowly intravenously as it counteracts the vasodilation caused by Verapamil, helping to normalize blood pressure levels. Sodium bicarbonate is not indicated for low blood pressure. Potassium chloride and magnesium sulfate are not the appropriate choices to address hypotension caused by Verapamil.
3. A patient is being discharged with a new prescription for Hydrochlorothiazide. Which of the following instructions should the nurse include?
- A. Take the medication before bedtime.
- B. Monitor for increased blood pressure.
- C. Take the medication with food.
- D. Monitor for leg cramps.
Correct answer: D
Rationale: The correct instruction the nurse should include is to monitor for leg cramps. Leg cramps can be a sign of hypokalemia, which is a potential adverse effect of Hydrochlorothiazide. By monitoring for leg cramps, the patient can detect signs of low potassium levels and report them to the healthcare provider promptly. This proactive approach helps prevent complications associated with hypokalemia. The other options are incorrect because taking Hydrochlorothiazide before bedtime or with food is not specific to the medication's adverse effects. Monitoring for increased blood pressure is not typically a common adverse effect of this medication.
4. A healthcare professional is preparing to administer Diltiazem IV to a client who has atrial fibrillation. Which of the following findings should the healthcare professional report immediately?
- A. Bradycardia.
- B. Hypertension.
- C. Shortness of breath.
- D. Tachycardia.
Correct answer: A
Rationale: The correct answer is bradycardia. Diltiazem, a calcium channel blocker, can lead to bradycardia as a side effect. Bradycardia should be reported immediately because it can result in serious cardiac complications, especially in a client with atrial fibrillation. Hypertension, shortness of breath, and tachycardia are not typically associated with Diltiazem administration and would not be immediate concerns in this scenario.
5. A client has a new prescription for Methotrexate. Which of the following instructions should be included in the teaching?
- A. Avoid drinking alcohol while taking this medication.
- B. Take the medication with a high-fat meal.
- C. Expect increased hair growth.
- D. You should never stop taking the medication without consulting your healthcare provider.
Correct answer: A
Rationale: The correct instruction for a client taking Methotrexate is to avoid drinking alcohol. Methotrexate can cause liver toxicity, and alcohol consumption can increase this risk. It is important to emphasize the avoidance of alcohol while on this medication to prevent adverse effects and ensure treatment effectiveness. The other options are incorrect: Taking Methotrexate with a high-fat meal is not necessary as it can be taken with or without food. Increased hair growth is not an expected effect of Methotrexate; in fact, hair loss is a potential side effect. Stopping the medication without consulting a healthcare provider can be dangerous and may lead to worsening of symptoms or relapse, making option D incorrect.
