                                    = 10 mL

Calculation:

Ordered Dose = 125 mg

= 2.5 mL

Calculation:

Ordered Dose = 125 mg

Available Dose = 250 mg

= (125 / 250) × 5

= 0.5 × 5

= 2.5 mL

Calculation:

Neither represents a smaller quantity: Both units measure volume, but their sizes differ. Deciliters are larger than centiliters, so it is inaccurate to say neither is smaller. Understanding metric prefixes helps clarify which unit is smaller.

Both are equal: Centiliters and deciliters are not equal in size. One deciliter equals ten centiliters, meaning their volumes are different. Recognizing metric relationships prevents confusion in conversions and measurements.

Deciliters: A deciliter represents 1/10 of a liter, which is larger than a centiliter (1/100 of a liter). Choosing deciliters as the smaller unit would be incorrect because they contain a greater volume than centiliters.

It ensures that the medication is within expiration date: Checking expiration is important but is only one aspect of safety; double-checking focuses on verifying the correct medication and dose.

It is a formality that does not impact safety: Double-checking is a critical safety measure, not a mere formality, especially for high-risk medications where errors can have serious consequences.

It allows nurses to practice teamwork and communication: While it does promote collaboration, the primary purpose of the double-check is to ensure accuracy and prevent medication errors.

Calculation:

1. meter = 100 centimeters

To convert 0.01 meters to centimeters, multiply the value in meters by 100:

Centimeters = Meters x 100

        = 0.01 x 100

        = 1

Calculation:

1. meter = 100 centimeters

To convert 0.01 meters to centimeters, multiply the value in meters by 100:

Centimeters = Meters x 100

        = 0.01 x 100

        = 1

Calculation:

1. meter = 100 centimeters

To convert 0.01 meters to centimeters, multiply the value in meters by 100:

Centimeters = Meters x 100

        = 0.01 x 100

        = 1

It lists contraindications for use: Contraindications are typically listed separately in prescribing information or patient leaflets, not in the brand name itself.

It provides detailed pharmacokinetic data: Pharmacokinetic information, such as absorption and metabolism, is not included in the brand name; this data is found in reference materials or drug monographs.

It shows the drug's chemical structure: The chemical structure is part of the scientific description of the drug, not indicated by the brand name on the label.

Calculation

• Convert the Ordered Dose to Milligrams (mg)

conversion factor: 1 g = 1,000 mg.

Ordered Dose (mg) = 1.5 g x 1,000 mg/g

                  = 1,500 mg

• Calculate the Number of Tablets

Ordered Dose (D): 1,500 mg

Available Dose (H): 500 mg

Tablets = Ordered Dose (D) / Available Dose (H)

= 1,500 mg / 500 mg

             = 3 tablets

Calculation

• Convert the Ordered Dose to Milligrams (mg)

conversion factor: 1 g = 1,000 mg.

Ordered Dose (mg) = 1.5 g x 1,000 mg/g

                  = 1,500 mg

• Calculate the Number of Tablets

Ordered Dose (D): 1,500 mg

Available Dose (H): 500 mg

Tablets = Ordered Dose (D) / Available Dose (H)

= 1,500 mg / 500 mg

             = 3 tablets

                  = 1,500 mg

• Calculate the Number of Tablets

Ordered Dose (D): 1,500 mg

Available Dose (H): 500 mg

Tablets = Ordered Dose (D) / Available Dose (H)

= 1,500 mg / 500 mg

             = 3 tablets

Discard the medication and record the refusal: While documenting the refusal is necessary, discarding the medication without further action does not address the reason for refusal or promote patient understanding and adherence. The nurse should first explore why the patient is refusing.

Notify the healthcare provider and wait for further instructions: Informing the provider is important, but waiting without engaging the patient may delay necessary treatment. Nursing intervention to educate the patient should occur first to support shared decision-making.

Leave the medication at the bedside for later use: Leaving the medication unattended can be unsafe, as the patient may take it incorrectly or it may be lost. Medications should only be administered when the patient is informed and agrees, ensuring safety and accountability.

The medication should be taken with antacids: Taking the medication with antacids may interfere with absorption for some drugs, but this is not universally required for patients with liver dysfunction. The primary concern is altered metabolism, not absorption.

The medication should be administered via a different route: Changing the route is not automatically necessary for liver dysfunction. Oral administration is usually safe unless the drug is extensively metabolized by the liver or the patient cannot take medications orally.

The medication's half-life will be reduced: Liver dysfunction typically slows metabolism, which prolongs the drug’s half-life rather than reducing it. A longer half-life increases the risk of accumulation and toxicity, making dose adjustment necessary.
