Nursing Elites

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 assessing a client who has a new prescription for chlorpromazine to treat schizophrenia. The client has a mask-like facial expression and is experiencing involuntary movements and tremors. Which of the following medications should the nurse anticipate administering?

• A. Amantadine
• B. Bupropion
• C. Phenelzine
• D. Hydroxyzine

Correct answer: A

Rationale: The correct answer is Amantadine. Amantadine is used to treat extrapyramidal symptoms, such as mask-like facial expressions, involuntary movements, and tremors, which are common side effects of antipsychotic medications like chlorpromazine. Bupropion is an antidepressant and not indicated for treating these symptoms. Phenelzine is a monoamine oxidase inhibitor used for depression and anxiety disorders, not for extrapyramidal symptoms. Hydroxyzine is an antihistamine used for anxiety and allergic conditions, not for the side effects described in the client.

3. A client with chronic kidney failure and an AV fistula for hemodialysis is prescribed epoetin alfa. Which of the following therapeutic effects should the nurse include in the teaching?

• A. Reduces blood pressure
• B. Inhibits clotting of fistula
• C. Promotes RBC production
• D. Stimulates growth of neutrophils

Correct answer: C

Rationale: The correct answer is C: Promotes RBC production. Epoetin alfa stimulates erythropoiesis (red blood cell production) to treat anemia associated with chronic kidney failure. This helps in increasing the hemoglobin levels and improving oxygen-carrying capacity. Choices A, B, and D are incorrect as epoetin alfa does not have direct effects on reducing blood pressure, inhibiting clotting of the fistula, or stimulating the growth of neutrophils.

4. A nurse is preparing to administer prochlorperazine 2.5 mg IV. Available is prochlorperazine injection 5 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth)

• A. 0.5 mL
• B. 0.005 mL
• C. 0.05 mL
• D. 5 mL

Correct answer: A

Rationale: To calculate the mL needed, set up a proportion: 5 mg / 1 mL = 2.5 mg / X mL. Cross multiply to find X: 5 * X = 2.5 * 1, X = 2.5 / 5 = 0.5 mL. Therefore, the nurse should administer 0.5 mL. Choice B, 0.005 mL, is incorrect as it doesn't match the calculated result. Choice C, 0.05 mL, is incorrect as it is ten times the correct value. Choice D, 5 mL, is incorrect as it represents the total volume of the entire vial, not the amount needed for the specific dose.

5. A nurse is preparing to administer lactated Ringer's (LR) 1,000 mL IV to infuse over 8 hr. The drop factor of the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number).

• A. 21 gtt/min
• B. 20 gtt/min
• C. 25 gtt/min
• D. 18 gtt/min

Correct answer: A

Rationale: To calculate the IV infusion rate in gtt/min: 1000 mL / 480 min × 10 gtt/mL = 20.83 ≈ 21 gtt/min. Therefore, the correct answer is A. Choice B (20 gtt/min) is incorrect because the calculation results in 20.83 gtt/min, rounded to 21. Choices C (25 gtt/min) and D (18 gtt/min) are incorrect as they are not the closest whole number approximation to the calculated value.
