A patient needs to receive a liquid medication dosage of 2 tablespoons. How many milliliters should the nurse administer?
A. 15 milliliters
Calculation: Ordered Dose = 2 tablespoons Conversion:1 tablespoon = 15 mL Volume in mL = Number of tablespoons × 15 mL = 2 × 15 = 30 mL
B. 30 milliliters
Calculation: Ordered Dose = 2 tablespoons Conversion:1 tablespoon = 15 mL Volume in mL = Number of tablespoons × 15 mL = 2 × 15 = 30 mL
C. 10 milliliters
Calculation: Ordered Dose = 2 tablespoons Conversion:1 tablespoon = 15 mL Volume in mL = Number of tablespoons × 15 mL = 2 × 15 = 30 mL
D. 25 milliliters
Calculation: Ordered Dose = 2 tablespoons Conversion:1 tablespoon = 15 mL Volume in mL = Number of tablespoons × 15 mL = 2 × 15 = 30 mL

Calculation:
Ordered Dose = 2 tablespoons
Conversion:1 tablespoon = 15 mL
Volume in mL = Number of tablespoons × 15 mL
= 2 × 15
= 30 mL
Similar Questions
In the formula method, what does 'Q' stand for?
A. Quality of the medication
Quality of the medication: Quality refers to the purity or potency of a drug, which is not represented by 'Q' in the formula method and does not impact the calculation directly.
B. Quantity of the drug form
Quantity of the drug form: In the D/H × Q formula, 'Q' represents the quantity of the dosage form available, such as tablets, capsules, or milliliters. This allows the nurse to calculate the exact amount of medication to administer safely.
C. Questioning the dosage
Questioning the dosage: While questioning unclear orders is important for safety, 'Q' in the formula does not represent questioning; it is a mathematical component used to determine dosage.
D. Quick administration
Quick administration: 'Q' does not indicate speed of administration. The formula is used to calculate the correct dose, not the rate at which it is given.

Which of the following actions by a nurse demonstrates adherence to the Right Route in medication administration?
A. Asking a colleague about the correct route for unfamiliar medications.
Asking a colleague about the correct route for unfamiliar medications: Consulting a colleague is a helpful safety measure, but it does not directly demonstrate adherence to the right route for the specific administration at that moment.
B. Checking the medication order and verifying the route with the drug label before administration.
Checking the medication order and verifying the route with the drug label before administration: Verifying the prescribed route against the medication label ensures the drug is given correctly, preventing administration errors and ensuring patient safety. This step directly aligns with the Right Route principle.
C. Administering a medication intravenously that is ordered for oral use.
Administering a medication intravenously that is ordered for oral use: This action violates the Right Route and can result in serious harm or toxicity, as different routes have different absorption rates and systemic effects.
D. Confirming the route with the patient before administration.
Confirming the route with the patient before administration: While patient confirmation adds a safety layer, the nurse must primarily rely on the provider’s order and drug label to ensure the correct route, as patients may not always know the proper method.

A physician orders 250 mg of a medication. The available dosage strength is 500 mg per 2 mL. Using the formula method, how much should the nurse administer?
A. 1 mL
Calculation using the Formula Method Desired Dose (D): 250 mg Dose on Hand (H): 500 mg Quantity (Q): 2 mL The formula method is: Amount to Administer = (Desired (D) / Have (H)) x Quantity (Q) = (250 mg / 500 mg) x 2 mL = 0.5 x 2 mL = 1 mL
B. 0.5 mL
Calculation using the Formula Method Desired Dose (D): 250 mg Dose on Hand (H): 500 mg Quantity (Q): 2 mL The formula method is: Amount to Administer = (Desired (D) / Have (H)) x Quantity (Q) = (250 mg / 500 mg) x 2 mL = 0.5 x 2 mL = 1 mL
C. 1.5 mL
Calculation using the Formula Method Desired Dose (D): 250 mg Dose on Hand (H): 500 mg Quantity (Q): 2 mL The formula method is: Amount to Administer = (Desired (D) / Have (H)) x Quantity (Q) = (250 mg / 500 mg) x 2 mL = 0.5 x 2 mL = 1 mL
D. 2 mL
Calculation using the Formula Method Desired Dose (D): 250 mg Dose on Hand (H): 500 mg Quantity (Q): 2 mL The formula method is: Amount to Administer = (Desired (D) / Have (H)) x Quantity (Q) = (250 mg / 500 mg) x 2 mL = 0.5 x 2 mL = 1 mL
Full Explanation
Calculation using the Formula Method
Desired Dose (D): 250 mg
Dose on Hand (H): 500 mg
Quantity (Q): 2 mL
The formula method is:
Amount to Administer = (Desired (D) / Have (H)) x Quantity (Q)
= (250 mg / 500 mg) x 2 mL
= 0.5 x 2 mL
= 1 mL
