The nurse is preparing 0900 medications for Patients A, B, C, and D.

Patient A: Order: vemurafenib 0.96 g PO daily; Available: 240 mg tablets

Patient B: Order: colchicine 1.2 mg PO today; Available: 0.6 mg tablets

Patient C: Order: citalopram 20 mg PO daily; Available: 10 mg/5 mL

Patient D: Order: ceftazidime 1 g IV every 12 hr; Available: 1 g/50 mL

Which of the following orders will require the nurse to do a conversion before administering the ordered 0900 medication?

Patient A

Patient B

Patient C

Patient D

Answer and Explanation

The Correct Answer is C

A. Patient A: The ordered dose is 0.96 g (960 mg) and the available tablets are 240 mg. The nurse can calculate the number of tablets needed directly (960 ÷ 240 = 4 tablets) without converting units, so no additional conversion is required.

B. Patient B: The order is 1.2 mg and the available tablets are 0.6 mg. The nurse can determine the number of tablets by simple division (1.2 ÷ 0.6 = 2 tablets) without unit conversion.

C. Patient C: The ordered dose is 20 mg, but the available medication is 10 mg/5 mL. The nurse must convert the desired dose into the corresponding volume (mL) to administer the correct amount orally, requiring a unit conversion.

D. Patient D: The order is 1 g IV, and the available concentration is 1 g/50 mL. Since the dose and available concentration are both in grams, the nurse can administer 50 mL directly, and no conversion between units is needed.

Correct Answer is C

Explanation

A. Administer extended-release tablets once a day: While extended-release formulations are often given once daily, the exact frequency must be confirmed with the prescriber’s order. The label alone does not specify the dosing schedule.

B. Instruct the patient to chew the tablet slowly: Extended-release tablets are formulated to release the drug over time. Chewing them can destroy the coating and cause rapid absorption, increasing the risk of adverse effects.

C. Instruct the patient to swallow the entire tablet: Swallowing the extended-release tablet whole ensures that the medication is released gradually as designed. This maintains therapeutic levels and reduces the risk of toxicity.

D. Crush and dissolve the tablet in 15 mL of water: Crushing or dissolving an extended-release tablet disrupts the controlled-release mechanism, potentially leading to overdose and loss of efficacy.

A. 15 mL = 3 tsp/1 tbsp B. 10 mL = 2 tsp C. 30 mL = 6 tsp D. 30 mL = ½ OZ

Correct Answer is D

Explanation

A. 15 mL = 3 tsp/1 tbsp: This is a correct conversion. One teaspoon equals 5 mL, so 3 teaspoons equal 15 mL, which also equals 1 tablespoon. This measurement is accurate and safe for patient use.

B. 10 mL = 2 tsp: One teaspoon equals 5 mL, so 2 teaspoons equal 10 mL. This conversion is correct and aligns with standard household equivalents.

C. 30 mL = 6 tsp: Six teaspoons multiplied by 5 mL per teaspoon equals 30 mL. This conversion is accurate and does not require questioning.

D. 30 mL = ½ OZ: One ounce equals 30 mL, so ½ ounce equals 15 mL, not 30 mL. This conversion is incorrect and could result in a doubling of the prescribed dose, making it unsafe.
