A medication'sstabilityrefers tohow well it maintains potency, effectiveness, and safety over time. Several factors candegrade medications, includingoxygen, moisture, temperature, and light.

Oxygen exposurecan causeoxidation, leading to drug degradation and loss of potency.

Many medications, especiallyvitamins (e.g., vitamin C), biologics, and certain antibiotics, are susceptible to oxidative damage.

Medications requiring protection from oxygen are often packaged inair-tight containersorblister packs.

A. Allergies→ Incorrect; allergies affect thepatient, not the drug’sstability.

B. Equivalence→ Incorrect; equivalence refers tobioavailabilitybetween generic and brand-name drugs, not drug stability.

D. Indications→ Incorrect; indications refer toapproved uses of a drug, not factors affecting its stability.

According to theCDC Hand Hygiene Guidelines,alcohol-based hand sanitizershould be used:

Before and after direct patient contact(if hands are not visibly dirty).

Before and after wearing gloves(if no contamination is visible).

Lorazepam oral concentrate is a high-potency liquid formulation often dispensed in 2 mg/mL. Due to its strength and risk of dosing errors, it must be dispensed with a calibrated oral syringe for accurate dosing, especially in pediatric or geriatric patients.

From Pharmacy Technician Certification Exam Review:

“Concentrated oral liquids should always be dispensed with calibrated measuring devices to prevent overdose or underdose.”

Other options:

Enoxaparin – subcutaneous injection

Albuterol/ipratropium – inhalation

Polyethylene glycol 3350 – powder mixed with water (no syringe required)

A. Intended effect→ Incorrect; the intended effect of ciprofloxacin isbacterial infection treatment, not photosensitivity.

C. Synergistic effect→ Incorrect; asynergistic effectoccurs whentwo drugs work togetherto produce a greater effect, which is not the case here.

D. Anaphylactic reaction→ Incorrect;anaphylaxisis asevere allergic reactionwithrespiratory distress, hypotension, and swelling, not photosensitivity.
