1. A nurse is preparing to administer heparin 8,000 units subcutaneously every eight hours. The amount available is heparin injection 10,000 units/mL. How many milliliters should the nurse administer per dose? (Round the answer to the nearest tenth)
- A. 0.8 mL
- B. 0.9 mL
- C. 10.0 mL
- D. 98.0 mL
Correct answer: A
Rationale: To determine the volume of heparin to administer per dose, divide the prescribed dose (8,000 units) by the concentration of heparin available (10,000 units/mL). 8000 units / 10000 units/mL = 0.8 mL. Therefore, the nurse should administer 0.8 mL per dose. Choice B, 0.9 mL, is incorrect as the correct calculation results in 0.8 mL. Choices C and D are significantly higher and incorrect, indicating an inaccurate calculation.
2. A nurse is administering insulin glulisine 10 units subcutaneously at 0730 to an adolescent client who has type 1 diabetes mellitus. The nurse should anticipate the onset of action of the insulin at which of the following times?
- A. 0745
- B. 0700
- C. 0645
- D. 0457
Correct answer: A
Rationale: Insulin glulisine has a rapid onset of action, typically around 15 minutes. Therefore, the nurse should expect the onset around 0745. Choice A is correct as it aligns with the expected onset time. Choices B, C, and D are incorrect as they do not match the typical onset time of insulin glulisine.
3. A nurse is providing teaching to a group of new parents about medications. The nurse should include that aspirin is contraindicated for children who have a viral infection due to the risk of developing which of the following adverse effects?
- A. Reye's syndrome
- B. Visual disturbances
- C. Diabetes mellitus
- D. Wilms' tumor
Correct answer: A
Rationale: The correct answer is A: Reye's syndrome. Aspirin use in children with viral infections has been associated with Reye's syndrome, a serious condition that causes swelling in the liver and brain. Visual disturbances (choice B) are not typically associated with aspirin use in children with viral infections. Diabetes mellitus (choice C) and Wilms' tumor (choice D) are not adverse effects of aspirin use in this context.
4. A nurse is providing teaching to a client who has cirrhosis and a new prescription for lactulose. The nurse should instruct the client that lactulose has which of the following therapeutic effects?
- A. Increases blood pressure
- B. Prevents esophageal bleeding
- C. Decreases heart rate
- D. Reduces ammonia levels
Correct answer: D
Rationale: The correct answer is D: Reduces ammonia levels. Lactulose is used to reduce blood ammonia levels in clients with hepatic encephalopathy. Options A, B, and C are incorrect because lactulose does not have the therapeutic effect of increasing blood pressure, preventing esophageal bleeding, or decreasing heart rate.
5. A client with a severe urinary tract infection (UTI) asks why both ciprofloxacin and phenazopyridine are needed. Which of the following responses should the nurse make?
- A. Phenazopyridine decreases adverse effects of ciprofloxacin.
- B. Combining phenazopyridine with ciprofloxacin shortens the course of therapy.
- C. The use of phenazopyridine allows for a lower dosage of ciprofloxacin.
- D. Ciprofloxacin treats the infection, and phenazopyridine treats pain.
Correct answer: D
Rationale: Ciprofloxacin is an antibiotic that treats the infection, while phenazopyridine is a urinary analgesic that relieves pain. Choice A is incorrect because phenazopyridine does not decrease adverse effects of ciprofloxacin; it primarily addresses pain. Choice B is incorrect because combining phenazopyridine with ciprofloxacin does not shorten the course of therapy; they serve different purposes. Choice C is incorrect because the use of phenazopyridine does not allow for a lower dosage of ciprofloxacin; they have independent roles in UTI management.
