1. A healthcare professional is preparing to administer acetaminophen 650 mg PO every 6 hr PRN for pain. The amount available is acetaminophen liquid 500 mg/5 mL. How many mL should the healthcare professional administer per dose?
- A. 6.5 mL
- B. 7 mL
- C. 5 mL
- D. 8 mL
Correct answer: A
Rationale: To calculate the volume to administer: (Desired dose / Concentration) = Volume to administer. In this case, (650 mg / 500 mg) x 5 mL = 6.5 mL. Therefore, the healthcare professional should administer 6.5 mL of acetaminophen per dose to achieve the desired 650 mg dose for pain relief. Choice A is correct because it accurately calculates the volume required based on the concentration of the liquid acetaminophen. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the concentration of the liquid medication and the desired dose.
2. Which of the following is not a side effect of loop diuretics?
- A. Alkalosis
- B. Nausea
- C. Hypotension
- D. Potassium deficits
Correct answer: B
Rationale: Nausea is not commonly associated with loop diuretics. Loop diuretics are known to cause electrolyte imbalances such as potassium deficits, metabolic alkalosis, and hypotension due to excessive fluid loss. Nausea is not a typical side effect of loop diuretics.
3. Which of the following conditions is not treated with Prednisone?
- A. Cushing’s disease
- B. Testicular cancer
- C. Lymphomas
- D. Chronic leukemias
Correct answer: B
Rationale: Prednisone is not a common treatment for testicular cancer. Prednisone is used in conditions like Cushing’s disease, lymphomas, and chronic leukemias due to its anti-inflammatory and immunosuppressive properties. However, testicular cancer treatment typically involves surgery, chemotherapy, and radiation therapy, but not Prednisone.
4. A client is taking Epoetin Alfa for anemia. Which of the following laboratory tests should the nurse monitor to evaluate the effectiveness of the therapy?
- A. White blood cell count
- B. Platelet count
- C. Hematocrit
- D. Serum potassium level
Correct answer: C
Rationale: The nurse should monitor the hematocrit level to evaluate the effectiveness of Epoetin Alfa therapy. Epoetin Alfa stimulates red blood cell production, leading to an increase in hematocrit levels. Monitoring the hematocrit helps assess the response to therapy and ensures that the medication is effectively addressing the anemia. White blood cell count and platelet count are not directly affected by Epoetin Alfa therapy. Serum potassium level monitoring is important for other medications that may impact potassium levels but is not specifically relevant to assessing the effectiveness of Epoetin Alfa in treating anemia.
5. A provider prescribes phenobarbital for a client who has a seizure disorder. The medication has a long half-life of 4 days. How many times per day should the nurse expect to administer this medication?
- A. One
- B. Two
- C. Three
- D. Four
Correct answer: A
Rationale: Phenobarbital, with a long half-life of 4 days, remains at therapeutic levels in the body for an extended period. Due to this prolonged duration of action, the nurse should administer phenobarbital once a day to maintain a consistent therapeutic effect without the need for multiple daily doses. Administering the medication more than once a day would not be necessary and could increase the risk of side effects or toxicity. Therefore, the correct answer is to administer phenobarbital once a day.
