Itworks by increasing acetylcholine levels in the brain, improving memory and cognitive function.

FDA-approved for all stages of Alzheimer’s disease.

B. Azilect❌→Used for Parkinson’s disease, not Alzheimer's.

Azilect (Rasagiline) is a monoamine oxidase-B (MAO-B) inhibitorthat helps manage Parkinson’s symptoms but is not indicated for dementia.

C. Ambien❌→Used for insomnia, not Alzheimer's dementia.

Ambien (Zolpidem) is a sedative-hypnotic for sleep disordersand does not treat cognitive decline.

D. Atacand❌→Used for hypertension, not dementia.

Atacand (Candesartan) is an angiotensin receptor blocker (ARB) used to treat high blood pressure and heart failure.

FDA Approved Uses for Donepezil (Aricept)– Confirms its indication for all stages of Alzheimer’s disease.

Alzheimer’s Association Treatment Guidelines– Listscholinesterase inhibitors as first-line therapy for dementia.

PTCB PTCE Exam Content Outline– Covers pharmacologic treatments for cognitive disorders.

Why Not the Other Options?Key References:

Step 1: Convert pounds to kilograms

1 kg = 2.2 lbs

132 lbs ÷ 2.2 = 60 kg

Step 2: Calculate total dose

5 mg/kg × 60 kg = 300 mg

Thus, the correct answer isC. 660 mg.

Linaclotide (brand name: Linzess)must be dispensed in its original containerbecause:

It is highly moisture-sensitive, and removing it from its original container may lead to degradation.

The manufacturer provides a desiccantin the original packaging toprotect against humidity.

A. Furosemide❌→Does not require original container.

While furosemide tablets should be stored properly,they do not require dispensing in the original container.

C. Valsartan❌→Does not require original container.

Valsartan tablets arestable outside the original container.

D. Sertraline❌→Does not require original container.

Sertraline (Zoloft)can be repackagedwithout stability issues.

FDA Linzess Storage Guidelines– States that Linzessmust be stored in its original container with desiccant.

USP <797> & <800> Guidelines– Cover proper storage and handling of moisture-sensitive drugs.

PTCB PTCE Exam Content Outline– Includes special drug storage requirements.

ISMP maintains a “List of Confused Drug Names” highlighting look-alike/sound-alike name pairs with a history of mix-ups. Chlordiazepoxide (a benzodiazepine) and chlorpromazine (a typical antipsychotic) are a classic LASA pair on ISMP lists and in technician study materials, given their similar prefixes (“chlor…”) and length/appearance, leading to documented wrong-drug errors. While other pairs may also resemble one another, ISMP’s established examples include chlordiazepoxide/chlorpromazine specifically.

USP <800> mandates that hazardous drug exposure requires immediate decontamination.

Flushing the affected area with large amounts of water for at least 15minutes is the first step.

For eye exposure, an eye wash station must be used immediately.

Why Other Options Are Incorrect:

A. Writing a report first?❌Incident reports should be done AFTER flushing the area.

B. Ice bag?❌Ice can worsen chemical burns.

C. Soapy water?❌Soap may react with chemicals, causing further irritation.

Nitroglycerin sublingual tablets are light- and moisture-sensitive, requiring storage in tight, light-resistant containers. Removing them from their original glass container can compromise potency. Therefore, they must always be dispensed in the original container provided by the manufacturer.

According to USP Packaging and Storage Requirements and Mosby’s Pharmacy Technician:

“Nitroglycerin SL tablets lose potency quickly when exposed to air or light. Do not repackage; dispense only in manufacturer-supplied container.”

Other options do not require original container for stability:

Methotrexate – may be repackaged

Metoprolol XL – stable in unit-dose or amber vials

Allopurinol – routine packaging allowed
