The nurse reads the following on the heparin drug label:
HEPARIN
20,000
USP units per mL
1-mL Multi-Dose Vial
The nurse correctly determines:
HEPARIN contains tall man lettering.
HEPARIN is the brand name of the drug.
The vial must be discarded after the first dose regardless of the dose administered.
The vial can be used for the administration of multiple doses.
The Correct Answer is D
A. HEPARIN contains tall man lettering: Tall man lettering is used to differentiate look-alike or sound-alike drug names, usually by capitalizing parts of the name. In this case, the label uses all capital letters for the drug name, which is standard labeling, not tall man lettering.
B. HEPARIN is the brand name of the drug: HEPARIN is the generic name of the medication. Brand names are typically capitalized and trademarked, whereas this label shows the generic drug name.
C. The vial must be discarded after the first dose regardless of the dose administered: The label specifies it is a 1-mL multi-dose vial. Multi-dose vials are intended for multiple uses, so discarding after the first dose is unnecessary unless sterility is compromised.
D. The vial can be used for the administration of multiple doses: The label clearly states “1-mL Multi-Dose Vial,” indicating that it is designed for multiple administrations. Proper aseptic technique must be used for each withdrawal to maintain sterility.

Correct Answer is B
Explanation
- Calculate the number of tablets per dose:
Ordered dose = 25 mg
Available tablet strength = 50 mg per tablet
Tablets to administer = (Ordered dose / Available strength)
= (25 mg / 50 mg/tablet)
= 0.5 tablet (or 1/2 tablet).
Correct Answer is C
Explanation
A. Injected into the subcutaneous tissue: Subcutaneous injections deliver medication into the fatty tissue under the skin. This route is not appropriate for a sublingual order and would prevent rapid absorption through the oral mucosa.
B. Placed between the gum and lining of the cheek: This describes the buccal route, which allows absorption through the cheek lining. While similar to sublingual, it is not the intended route for a sublingual medication, which must be placed under the tongue for rapid systemic absorption.
C. Placed under the tongue: Sublingual administration involves placing the medication beneath the tongue, allowing it to dissolve and absorb directly into the bloodstream. This route bypasses the gastrointestinal tract and first-pass metabolism, providing rapid onset of action.
D. Inhaled through the nasal mucosa: Nasal administration delivers medication through the respiratory mucosa and is not appropriate for sublingual drugs. Using this route would result in improper absorption and therapeutic effect.
