7.4 Physical Measurements, Point-of-Care Testing & Supporting Medication Administration
Key Takeaways
NAPRA's 2024 competencies expect pharmacy technicians to measure height, weight and blood pressure accurately and to record weight in kilograms, noting whether it was measured or self-reported.
Technicians perform point-of-care tests only when an authorized health professional has recommended them, and the pharmacist or ordering professional interprets the result.
Blood pressure is measured after about 5 minutes of seated rest, with the back supported, feet flat, arm at heart level, and a cuff whose bladder encircles 80% to 100% of the arm.
Where a province authorizes it, trained pharmacy technicians may administer certain injections, but only after the patient has been assessed and the order confirmed.
Anaphylaxis after an injection is treated at once with intramuscular epinephrine 1 mg/mL into the anterolateral thigh and a 911 call, following the pharmacy's protocol.
Physical Measurements, Point-of-Care Testing & Supporting Medication Administration
Exam Tip: NAPRA's 2024 competencies expect a pharmacy technician to measure a patient's physical attributes (height, weight, blood pressure), perform point-of-care tests that an authorized health professional has recommended, support the care plan, and, where the province authorizes it, administer medications by injection and respond to adverse effects of administration. PEBC blueprint key competencies 1.1, 1.2, 1.4 and 1.5 all sit in Providing Care: Clinical Care (17% of Part I). The recurring exam theme is that the technician gathers accurate data and acts within the ordered plan, and the pharmacist or another authorized professional interprets the results.
1. Measuring Physical Attributes (NAPRA 1.1.4a)
Accurate measurements feed directly into dosing checks that the pharmacist performs, such as mg/kg pediatric doses, creatinine clearance, and body surface area for chemotherapy.
| Measurement | Technique Points | Why It Matters |
|---|---|---|
| Weight | Calibrated scale on a flat surface; light clothing, shoes off; record in kilograms and note whether measured or self-reported. | Pediatric mg/kg dosing, Cockcroft-Gault creatinine clearance, weight-based anticoagulants. |
| Height | Stadiometer, heels together against the wall, head level; record in centimetres. | Body mass index and body surface area (Mosteller). |
| Blood pressure | Seated with back supported, feet flat, legs uncrossed, arm at heart level, after about 5 minutes of quiet rest; correct cuff size (bladder encircling 80% to 100% of the arm); no talking during the reading; repeat and record per protocol. | Screening and monitoring of hypertension. A cuff that is too small reads falsely high; a cuff that is too large reads falsely low. |
| Heart rate | Count for 30 to 60 seconds, or use the validated automated device reading. | Context for beta-blocker, digoxin or stimulant monitoring. |
Scope boundary: The technician measures and records accurately. If a reading falls outside the pharmacy's referral thresholds, or the patient has symptoms (e.g., chest pain, severe headache, blurred vision with a very high reading), the technician immediately involves the pharmacist and follows the emergency protocol. The technician does not diagnose.
2. Point-of-Care Testing (NAPRA 1.2.5a)
NAPRA's wording is specific: pharmacy technicians perform point-of-care tests that have been recommended for the patient by an authorized health professional. Examples include capillary blood glucose, INR fingerstick monitoring, lipid panels, and rapid antigen or strep tests, where the province and the pharmacy's program allow them.
Core technique for a capillary (fingerstick) test:
- Confirm the order or recommendation, the patient's identity (two identifiers), and consent.
- Check the device: in-date strips or cartridges, quality-control check completed and logged, device calibrated.
- Clean the site and let it dry completely, then lance the side of the fingertip.
- Wipe away the first drop if the device instructions say so, and fill the strip without smearing or squeezing hard, since heavy squeezing dilutes the sample with tissue fluid.
- Dispose of the lancet directly into a sharps container; record the result, device, lot and time.
- Hand the result to the pharmacist (or the authorized professional who ordered it) for interpretation. The technician does not tell the patient what the number means for their therapy.
Infection-prevention rules apply to every test: hand hygiene, gloves, single-use lancets, and cleaning and disinfecting the device between patients according to the manufacturer's instructions.
3. Supporting the Care Plan (NAPRA 1.4.3a to 1.4.5a)
Technicians help put the pharmacist's and prescriber's plan into action without making clinical decisions:
- Support implementation (1.4.3a): schedule follow-up appointments, prepare compliance packaging that reflects a dose change, arrange delivery, and complete third-party paperwork.
- Medical device selection (1.4.4a): help the patient choose a device only after an authorized health professional has recommended it, for example a valved holding chamber, a blood glucose meter model the pharmacist recommended, or a pill splitter.
- Non-clinical information (1.4.5a): explain storage, how to use a device, refill timing, and cost coverage. Anything that needs clinical or therapeutic knowledge (side effects, whether to take a missed dose, interactions) goes to the pharmacist.
4. Administering Medications and Responding to Reactions (NAPRA 1.4.1 and 1.4.2)
NAPRA lists "administer medication by injection and other routes, using aseptic technique" and "respond to adverse effects related to medication administration" as competencies for pharmacy professionals. The authority to inject is provincial, and several provinces now allow trained, authorized pharmacy technicians to administer certain vaccines or injections. NAPRA notes that professionals who administer medications should also meet the Public Health Agency of Canada's immunization competencies.
Before the injection:
- Confirm that the pharmacist or another authorized prescriber has assessed the patient and that the product, dose, route and site match the order.
- Screen using the pharmacy's form (previous reactions, allergies to components, current illness), obtain informed consent, and document it.
- Prepare the dose with aseptic technique; check the product, expiry, cold chain and appearance.
Common injection technique points:
- Intramuscular (IM): deltoid for most adults, anterolateral thigh for infants; 90-degree angle; needle length chosen for the patient's size.
- Subcutaneous (SC): back of the upper arm or abdomen; commonly a 45-degree angle, or 90 degrees with a short pen needle.
- Dispose of the needle immediately in a sharps container. Do not recap unless the device is designed for it.
After the injection:
- Observe the patient for the period required by the pharmacy's protocol (commonly 15 minutes after vaccination, and longer when there is a specific concern).
- Fainting (vasovagal syncope): have the patient sit or lie down, protect them from falling, and monitor until they recover. Syncope usually resolves quickly and has no hives or breathing difficulty.
- Anaphylaxis: sudden hives or swelling, difficulty breathing, wheeze, or low blood pressure within minutes. Follow the pharmacy's anaphylaxis protocol at once: call 911, give intramuscular epinephrine 1 mg/mL (1:1,000) into the anterolateral thigh, commonly 0.01 mg/kg up to 0.5 mg for adults (0.3 mg or 0.5 mg in practice, or an auto-injector of the right strength), repeat the dose after about 5 minutes if there is no improvement (as the protocol directs), position the patient, and monitor. Document the event and report the adverse event following immunization to public health.
5. Gathering Monitoring Information (NAPRA 1.5.1a to 1.5.3a)
At refill time, the technician can collect information the pharmacist needs to monitor therapy: home blood pressure or glucose logs, how the patient is using a device, and whether refills are early or late. The technician passes on concerns about adherence or device problems, and the pharmacist decides what they mean clinically.
A registered pharmacy technician is asked to take a patient's blood pressure for the pharmacist's hypertension follow-up. The patient has just climbed two flights of stairs, is sitting with legs crossed, and has a large upper arm that the standard adult cuff barely closes around. What should the technician do?
Take the reading immediately with the standard cuff so the patient is not kept waiting, and add 10 mmHg to correct for the small cuff.
Have the patient rest seated for about 5 minutes with back supported, feet flat and legs uncrossed, use a larger cuff whose bladder encircles 80% to 100% of the arm, then measure with the arm at heart level.
Measure over the patient's sweater sleeve with the arm hanging at the side, because clothing protects the skin from the cuff.
Skip the measurement and ask the patient to report their usual home reading, since technicians should not take blood pressure.
A pharmacy runs an INR point-of-care testing program. A patient on warfarin asks the registered pharmacy technician to do a fingerstick INR test 'and tell me whether I should change my dose,' but the patient's record has no recommendation or order for testing. What is the most appropriate response?
Perform the test and advise the patient to take half a tablet less if the result is above 3.0.
Perform the test and tell the patient the result is normal if it is between 1.0 and 4.0.
Refuse to involve anyone, because INR testing is outside pharmacy practice in all provinces.
Explain that the test is done when it has been recommended by an authorized health professional, involve the pharmacist to assess and order or arrange it, and leave interpretation and dosing advice to the pharmacist.
Two minutes after a technician authorized by the province to administer vaccines gives an intramuscular influenza vaccine, the patient develops widespread hives, throat tightness and wheezing. Which action should come first under a standard pharmacy anaphylaxis protocol?
Give intramuscular epinephrine 1 mg/mL into the anterolateral thigh at the protocol dose and call 911, then monitor and repeat epinephrine after about 5 minutes if there is no improvement, as the protocol directs.
Give an oral antihistamine and observe for 30 minutes before deciding whether to call for help.
Have the patient lie down and wait, because this is most likely a vasovagal faint that will resolve on its own.
Give epinephrine 0.1 mg/mL (1:10,000) intravenously through a new peripheral line.
