The nurse is reviewing a metric to household equivalent measurement conversion chart. Which of the following written equivalent measurements would the nurse question?

15 mL = 3 tsp/1 tbsp

10 mL = 2 tsp

30 mL = 6 tsp

30 mL = ½ OZ

Answer and Explanation

The Correct Answer is D

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.

Correct Answer is A

Explanation

A. The tablets in the new refill contain the same amount of medication: 0.75 mg is equivalent to 750 mcg (1 mg = 1000 mcg), so the dose strength has not changed. The patient is receiving the same amount of active drug.

B. The tablets in the refill bottle contain less medication: Converting 0.75 mg to micrograms shows it equals 750 mcg, so the refill does not contain less medication.

C. The tablets in the refill bottle have a greater dose of medication: The dose is identical, not greater. There is no change in the amount of active ingredient per tablet.

D. The pharmacy needs to provide tablets that contain 750 mcg of medication: Although the labeling changed, 0.75 mg is equivalent to 750 mcg. The refill is correct and safe to use.

A. Question the metformin HCI order. B. Prepare to administer the 0900 medications. C. Clarify the digoxin order. D. Clarify the hydrochlorothiazide order.

Correct Answer is C

Explanation

A. Question the metformin HCI order: Metformin 500 mg PO daily at 0900 is a standard dose for type 2 diabetes management. There is no immediate concern with the dose or timing that would make it unsafe or require urgent clarification. It can be prepared as scheduled.

B. Prepare to administer the 0900 medications: While administering medications on time is important, the nurse must first ensure that all prescriptions are safe and accurate. Administering digoxin without clarifying a potentially unsafe dose could put the client at risk for toxicity.

C. Clarify the digoxin order: Digoxin 0.25 mg PO daily is commonly prescribed, but decimal errors are a frequent source of medication mistakes. The nurse must verify the order with the healthcare provider before administration to prevent overdose or underdose, which could cause serious cardiac complications.

D. Clarify the hydrochlorothiazide order: Hydrochlorothiazide 25 mg every 12 hours is a typical regimen for hypertension or fluid management. The dose is standard, and there is no immediate safety concern requiring urgent clarification.
