Strength And Dose - Pharmacy Technician Certification Exam Ptce
- Choose the correct product: Rx says "bupropion XL 150 mg"; options are SR 150 mg or XL 150 mg tablets.
- Bupropion XL 150 mg tablets. XL indicates 24-hour extended-release, differing from SR which is typically 12-hour sustained-release.
- What does the abbreviation "soln" indicate as the required dosage form on a prescription label?
- Solution. "Soln" refers to a homogeneous liquid dosage form where the active ingredient is fully dissolved, not requiring shaking.
- Find the correct dosage form: Rx says "clotrimazole 1% cream"; options are 1% cream or 1% topical solution.
- Clotrimazole 1% cream. Prescriptions specify dosage forms; cream is a semi-solid emulsion for skin application, unlike liquid topical solutions.
- What does the abbreviation "inj" indicate as the required dosage form on a prescription?
- Injection. "Inj" specifies a sterile dosage form intended for parenteral administration via needle or syringe.
- Choose the correct strength: Rx says "morphine sulfate oral solution 10 mg/5 mL"; stock is 2 mg/mL solution.
- 2 mg/mL solution (equivalent to 10 mg/5 mL). 2 mg/mL equals 10 mg/5 mL because 5 mL × 2 mg/mL = 10 mg, confirming equivalent concentrations.
- Which option is correct when a prescription specifies "chewable" for an oral tablet?
- Dispense chewable tablet dosage form. Chewable tablets are formulated to be chewed before swallowing, often for better palatability or absorption.
- Which option is correct when a prescription specifies "enteric-coated" for an oral tablet?
- Dispense an EC/DR product, not IR. Enteric-coated tablets are delayed-release to protect the drug from stomach acid, unlike immediate-release forms.
- Which option is correct when a prescription specifies "oral solution" rather than "oral suspension"?
- Dispense solution (no shaking required). Oral solutions are homogeneous liquids that do not separate, unlike suspensions which require shaking to redistribute particles.
- What does the abbreviation "cap" indicate as the required dosage form on a prescription?
- Capsule. "Cap" is a common abbreviation in prescriptions denoting the capsule dosage form for oral administration.
- What does the abbreviation "IR" indicate about the release characteristics of an oral dosage form?
- Immediate-release. "IR" indicates a formulation that releases the drug quickly for immediate therapeutic effect.
- Identify the correct strength to dispense: Rx says "levothyroxine 0.05 mg"; options are 50 mcg or 0.5 mg tablets.
- 50 mcg tablets. 0.05 mg equals 50 mcg, as 1 mg = 1000 mcg, ensuring accurate strength conversion for thyroid medication.
- What does the abbreviation "ODT" indicate as the required dosage form on a prescription?
- Orally disintegrating tablet. "ODT" refers to tablets designed to disintegrate rapidly in the mouth without water for easier administration.
- What does the abbreviation "DR" indicate about the release characteristics of an oral dosage form?
- Delayed-release (often enteric-coated). "DR" refers to formulations that release the drug after a delay, often protected by enteric coating to bypass stomach acid.
- Identify the correct strength to dispense: Rx says "digoxin 125 mcg"; stock is labeled 0.125 mg tablets.
- 0.125 mg tablets. 125 mcg converts to 0.125 mg since 1000 mcg = 1 mg, matching the stock labeling for precise dosing.
- What does the abbreviation "ER" indicate about the release characteristics of an oral dosage form?
- Extended-release. "ER" denotes a formulation that releases the drug over an extended period to maintain therapeutic levels longer.
- What does the abbreviation "SR" indicate about the release characteristics of an oral dosage form?
- Sustained-release. "SR" describes a formulation that releases the drug gradually over time to prolong its action.
- Choose the correct product: Rx says "metoprolol succinate ER 50 mg"; options are tartrate IR 50 mg or succinate ER 50 mg.
- Metoprolol succinate ER 50 mg. Metoprolol succinate is the extended-release salt form, distinct from the immediate-release tartrate salt.
- What does the abbreviation "SL" indicate about the route and dosage form for a tablet?
- Sublingual tablet. "SL" specifies administration under the tongue for rapid absorption, typically for tablets that dissolve quickly.
- What does the abbreviation "tab" indicate as the required dosage form on a prescription?
- Tablet. "Tab" is a standard abbreviation used in prescriptions to specify the tablet dosage form for oral medications.
- What does the abbreviation "supp" indicate as the required dosage form on a prescription?
- Suppository. "Supp" indicates a solid dosage form designed for insertion into body cavities like the rectum or vagina.
- Identify the dosage form to dispense: Rx says "nitroglycerin 0.4 mg SL"; stock has 0.4 mg transdermal patches.
- 0.4 mg sublingual tablets. SL specifies sublingual route for rapid onset, incompatible with transdermal patches designed for skin application.
- What does the abbreviation "susp" indicate as the required dosage form on a prescription label?
- Suspension. "Susp" denotes a liquid dosage form where solid particles are dispersed in a vehicle, requiring shaking before use.
- Identify the correct dosage form: Rx says "albuterol HFA inhaler"; options are nebulizer solution or HFA MDI.
- Albuterol HFA metered-dose inhaler. HFA specifies hydrofluoroalkane propellant in metered-dose inhalers, distinct from nebulizer solutions requiring a device.
- Identify the strength to dispense: Rx says "amoxicillin 500 mg caps"; stock has 250 mg/5 mL suspension.
- Do not substitute; prescription requires 500 mg capsules. Prescriptions specify dosage forms; substituting suspension for capsules alters administration and may affect bioavailability.
