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 providing teaching to a newly licensed nurse about administering morphine via IV bolus to a client. Which of the following information should the nurse include in the teaching?
- A. Respiratory depression can occur within 7 minutes after the morphine is administered.
- B. The morphine will peak within a few minutes.
- C. Withhold the morphine if the client has a respiratory rate less than 16/min.
- D. Administer the morphine over 2 minutes.
Correct answer: A
Rationale: The correct answer is A because respiratory depression is a significant risk when administering morphine, and it can occur within 7 minutes after administration. This information is crucial for the nurse to recognize and respond promptly. Choice B is incorrect because the peak effect of morphine via IV bolus is typically reached within a few minutes, not specifically 10 minutes. Choice C is incorrect because withholding morphine based solely on a respiratory rate less than 16/min may not be appropriate without considering other factors such as pain level, oxygen saturation, and overall respiratory status. Choice D is incorrect because administering morphine over 2 minutes may not prevent respiratory depression if it occurs rapidly after administration. Nurses should be vigilant for signs of respiratory depression regardless of the administration duration.
3. A nurse is providing teaching to a client who has a new prescription for hydrochlorothiazide 50 mg PO daily to treat hypertension. Which of the following instructions should the nurse include in the teaching?
- A. Take hydrochlorothiazide as needed for edema.
- B. Check your weight once weekly.
- C. Take the hydrochlorothiazide on an empty stomach.
- D. Take the hydrochlorothiazide in the morning.
Correct answer: D
Rationale: The correct answer is to take hydrochlorothiazide in the morning. This medication is usually advised to be taken in the morning to prevent nocturia, which is excessive urination at night. Option A is incorrect because hydrochlorothiazide should be taken daily as prescribed, not as needed for edema. Option B is incorrect as monitoring weight weekly may not be specifically related to hydrochlorothiazide therapy. Option C is incorrect as hydrochlorothiazide does not need to be taken on an empty stomach.
4. A nurse is caring for an older adult client who has a prescription for zolpidem at bedtime to promote sleep. The nurse should plan to monitor the client for which of the following adverse effects?
- A. Ecchymosis
- B. Decreased urine output
- C. Increased blood pressure
- D. Dizziness
Correct answer: D
Rationale: The correct answer is D: Dizziness. Zolpidem is known to cause dizziness, especially in older adults. This adverse effect can increase the risk of falls and injuries in the elderly population. Monitoring for dizziness is crucial to ensure patient safety. Choice A, Ecchymosis, is the development of bruising and is not a common adverse effect of zolpidem. Choices B and C, Decreased urine output and Increased blood pressure, are not typically associated with zolpidem use. Therefore, they are incorrect choices in this scenario.
5. A nurse is planning to administer chlorothiazide 20 mg/kg/day PO divided equally and administered twice daily for a toddler who weighs 28.6 lb. The amount available is chlorothiazide oral suspension 250 mg/5 mL. How many mL should the nurse administer per dose? (Round to the nearest tenth)
- A. 2.6 mL
- B. 2.63 mL
- C. 2.7 mL
- D. 2.2 mL
Correct answer: A
Rationale: To find the dose per administration, first convert the toddler's weight to kg: 28.6 lb ÷ 2.2 = 13 kg. Then calculate the total daily dose: 20 mg/kg × 13 kg = 260 mg/day. Since it is divided into two doses, each dose is 130 mg. The concentration of the oral suspension is 250 mg/5 mL = 50 mg/mL. Therefore, to find the volume needed per dose, divide the dose by the concentration: 130 mg ÷ 50 mg/mL = 2.6 mL per dose. Hence, the nurse should administer 2.6 mL per dose. Choices B, C, and D are incorrect as they do not accurately calculate the dosage of chlorothiazide needed per dose based on the toddler's weight and the concentration of the oral suspension.
