1. A nurse is preparing to administer amoxicillin 250 mg liquid suspension PO every 8 hr to an older adult client. The amount available is amoxicillin 50 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest whole number)
- A. 5 mL
- B. 6 mL
- C. 4 mL
- D. 7 mL
Correct answer: A
Rationale: To calculate the amount of amoxicillin in mL needed per dose, we can use the formula: 50 mg/mL = 250 mg / X mL. Cross multiply to solve for X: 50X = 250. Divide both sides by 50 to find X, which equals 5 mL per dose. Therefore, the nurse should administer 5 mL of amoxicillin per dose. Choice B, 6 mL, is incorrect as it does not match the calculated result. Choice C, 4 mL, is incorrect as it is too low based on the calculation. Choice D, 7 mL, is incorrect as it is too high based on the calculation.
2. A nurse is providing discharge teaching to a client who has heart failure and a new prescription for digoxin 0.215 mg PO daily and furosemide 20 mg PO daily. Which of the following statements by the client indicates an understanding of the teaching?
- A. I know that blurred vision is something I will expect to happen while taking digoxin.
- B. I will measure my urine output each day and document it in my diary.
- C. I will skip a dose of my digoxin if my resting heart rate is below 72 beats per minute.
- D. I will eat fruits and vegetables that have high potassium content every day.
Correct answer: D
Rationale: Clients taking digoxin and furosemide are at risk for hypokalemia. Eating potassium-rich foods can help maintain normal potassium levels.
3. 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.
4. A client with congestive heart failure taking digoxin reports nausea and refuses to eat breakfast. Which action should the nurse take first?
- A. Encourage the client to eat the toast on the breakfast tray.
- B. Administer an antiemetic.
- C. Inform the client's provider.
- D. Check the client's apical pulse.
Correct answer: D
Rationale: The correct action for the nurse to take first is to check the client's apical pulse. Nausea can be a sign of digoxin toxicity, and one of the early signs of digoxin toxicity is changes in the pulse rate. By checking the client's apical pulse, the nurse can assess if the digoxin level is too high. Encouraging the client to eat or administering an antiemetic may not address the underlying issue of digoxin toxicity. While informing the provider is important, assessing the client's condition through checking the apical pulse should be the immediate priority.
5. A nurse is caring for a client who has a new prescription for ergotamine. The nurse should recognize that ergotamine is administered to treat which of the following conditions?
- A. Raynaud's phenomenon
- B. Migraine headaches
- C. Ulcerative colitis
- D. Anemia
Correct answer: B
Rationale: Ergotamine is used to treat migraine headaches by constricting blood vessels in the brain. Therefore, the correct answer is B. Choice A, Raynaud's phenomenon, is incorrect as ergotamine is not indicated for this condition. Choice C, Ulcerative colitis, is incorrect as ergotamine is not used to treat this gastrointestinal disorder. Choice D, Anemia, is incorrect as ergotamine is not prescribed for anemia.
