Administration Equipment - Pharmacy Technician Certification Exam Ptce

Which patient group most commonly benefits from using a spacer with a metered-dose inhaler?

Patients with poor inhaler coordination (often children or older adults). Requires assistance to synchronize inhalation with actuation, making the device essential for optimal drug delivery.
Which syringe is specifically designed to measure and administer tuberculin tests?

Tuberculin syringe (1 mL with 0.01 mL graduations). Provides fine graduations for accurate measurement of small volumes required in intradermal injections for tuberculosis skin testing.
Identify the correct device for administering an intramuscular vaccine supplied as a single-dose prefilled unit.

Prefilled syringe with appropriate IM needle attached or supplied separately. Ensures sterile, ready-to-use delivery with a needle size (e.g., 23-25G, 1-1.5 inch) optimal for muscle penetration.
Which device is used to administer oral liquids accurately when small volumes are required?

Oral syringe (without a needle). Offers calibrated markings in milliliters for precise dosing, avoiding household spoons that can lead to errors.
Which device should be selected to transfer fluid between containers without using a needle and syringe?

Transfer spike (dispensing pin). Enables needle-free, sterile connection for efficient bulk fluid movement in compounding processes.
Which device should be selected to prevent coring when puncturing vial stoppers repeatedly?

Non-coring needle (Huber-type for appropriate systems). Designed with a beveled tip that displaces rather than cuts rubber, reducing particulate contamination.
Which device should be selected to administer medication via the rectal route in a measured volume?

Rectal syringe or rectal applicator tip. Allows for controlled insertion and delivery of suppositories or enemas with minimal discomfort.
Which needle type should be selected to withdraw medication from a vial efficiently, then replaced before injection?

Filter needle or large-bore draw-up needle, then change to injection needle. Facilitates withdrawal by filtering debris or allowing faster draw, with replacement ensuring patient safety.
Which filter size is commonly used to remove larger particles and clarify solutions (not sterilizing)?

$0.45\ \mu\text{m}$ filter. Traps visible particulates and some bacteria without fully sterilizing, suitable for pre-filtration steps.
Which administration device is used to deliver medication from a metered-dose inhaler more effectively?

Spacer (or valved holding chamber). Improves aerosol deposition in the lungs by holding the medication temporarily, reducing oropharyngeal loss.
Which device is used to deliver medication into the nose in a measured spray dose?

Nasal spray pump (metered spray device). Produces a fine mist for even distribution to nasal mucosa, ensuring consistent dosing per actuation.
Which option is appropriate for measuring $0.3\ \text{mL}$ of an oral solution for a pediatric dose?

Oral syringe (mL markings). Provides accurate calibration for small volumes, reducing dosing errors in sensitive populations.
Which syringe tip is preferred for thick or viscous liquids and faster medication transfer?

Catheter-tip syringe. Has a tapered, elongated tip that allows for easier flow of high-viscosity substances without clogging.
Which needle gauge should be selected when a smaller bore is needed (slower flow, less trauma)?

A higher gauge number (e.g., 25G is smaller than 18G). Denotes a finer diameter needle that minimizes tissue damage and is ideal for delicate injections requiring controlled flow.
Which device converts liquid medication into an inhalable mist for respiratory administration?

Nebulizer. Utilizes compressed air or ultrasonic power to aerosolize solutions for passive inhalation over several minutes.
Which administration tool is preferred for measuring larger oral liquid volumes for a patient dose?

Oral dosing cup (or calibrated dosing spoon). Provides volume graduations suitable for dispensing amounts like 5-30 mL accurately and conveniently.
Which IV filter is used to reduce particulate contamination for most aqueous IV solutions?

$0.2\ \mu\text{m}$ in-line IV filter. Captures microorganisms and small particles to maintain solution integrity during intravenous administration.
Which needle gauge should be selected when a larger bore is needed (faster flow)?

A lower gauge number (e.g., 18G is larger than 25G). Indicates a larger diameter needle that facilitates quicker fluid delivery and is suitable for viscous medications.
Which device should be selected to reduce needlestick injury risk during injections?

Safety needle or safety-engineered syringe device. Incorporates mechanisms like retractable needles or shields to comply with safety standards and minimize sharps injuries.
Which device is used to deliver medication into the eye while minimizing contamination risk?

Sterile ophthalmic dropper bottle (do not touch tip to eye). Delivers precise drops while the no-touch technique preserves sterility and prevents microbial introduction.
Which device is used to administer medication into the vagina (e.g., creams) in a measured dose?

Vaginal applicator. Enables targeted placement of semisolid formulations deep into the vaginal canal for effective absorption.
Which syringe type is used for very small doses and has markings in units (U)?

Insulin syringe (U-100 units scale). Features a specialized scale calibrated in insulin units for precise measurement of small subcutaneous doses, typically 0.3 to 1 mL capacity.
Which IV filter pore size is typically used for lipid-containing infusions such as TPN with lipids?

$1.2\ \mu\text{m}$ in-line filter. Permits passage of lipid emulsions while filtering out larger contaminants without obstructing flow.
Which syringe connection type reduces accidental disconnection by using a twist-lock design?

Luer-lock syringe. Employs a threaded collar that securely locks the needle in place, preventing slippage during high-pressure injections.
Which filter size is standard for sterilizing filtration of solutions during compounding?

$0.22\ \mu\text{m}$ sterile filter. Retains bacteria and most microorganisms, ensuring aseptic conditions in pharmaceutical preparations.
