1. A patient is prescribed acetaminophen 650 mg PO every 6 hr PRN for pain. The available acetaminophen liquid is 500 mg/5 mL. How many mL should the nurse administer per dose?

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 nurse should administer 6.5 mL of acetaminophen liquid per dose to provide the prescribed 650 mg of acetaminophen. Choice B, 7 mL, is incorrect because the correct calculation results in 6.5 mL. Choice C, 5 mL, is incorrect as it is the concentration of the acetaminophen liquid, not the final volume needed. Choice D, 8 mL, is incorrect because it does not reflect the accurate calculation based on the prescription and concentration.

2. Which of the following conditions are not treated with Barbiturates?

Correct answer: B

Rationale: Hypotension is not treated with barbiturates. Barbiturates are primarily used for treating seizures, insomnia, and anxiety, but they are not indicated for the treatment of hypotension.

3. What is the therapeutic use of Phenytoin?

Correct answer: C

Rationale: Phenytoin is primarily used to diminish seizure activity and is effective in terminating ventricular arrhythmias. It works by stabilizing neuronal membranes, reducing repetitive neuronal firing, and limiting the spread of seizure activity in the brain. While phenytoin does not have a direct role in preventing thrombus formation or extending existing thrombi, it is crucial in managing seizures and certain arrhythmias.

4. A client has a new prescription for Filgrastim. Which of the following instructions should be included by the healthcare provider?

Correct answer: C

Rationale: The correct answer is C: 'Report bone pain to your healthcare provider.' Filgrastim is known to cause bone pain as a common side effect. Therefore, it is crucial for clients to report any bone pain to their healthcare provider to monitor for potential complications or the need for further management. Choices A, B, and D are incorrect because taking Filgrastim with food, avoiding it with orange juice, and expecting a persistent cough are not relevant instructions associated with this medication.

5. A staff educator is reviewing medication dosages and factors that influence medication metabolism with a group of nurses at an in-service presentation. Which of the following factors should the educator include as a reason to administer lower medication dosages? (Select all that apply.)

Correct answer: C

Rationale: Liver failure impairs metabolism, leading to increased medication concentrations. When liver function is compromised, lower dosages are necessary to prevent adverse effects. Increased renal secretion is not a reason for lower medication dosages, as it primarily affects excretion rather than metabolism. Increased medication-metabolizing enzymes would usually require higher dosages to achieve the desired effect. Peripheral vascular disease does not directly impact medication metabolism or dosage requirements.
