Pharmacy Technician Certification Exam Answers

Question 1

The generic for Nasonex is:

Your Answer: Option(s)

Correct Answer: Option(s) A

Rationale

The generic for Nasonex is mometasone furoate.

Mometasone furoate is a corticosteroid used primarily in the treatment of allergic rhinitis and other inflammatory conditions. It is the active ingredient in Nasonex, which helps to reduce inflammation in the nasal passages.

A) mometasone furoate
This is the correct answer, as mometasone furoate is the active ingredient in Nasonex. It functions by inhibiting inflammatory responses, making it effective for treating nasal symptoms associated with allergies.

B) loteprednol etabonate
Loteprednol etabonate is another corticosteroid, but it is primarily used in the treatment of ocular conditions, such as inflammation after eye surgery. It does not pertain to Nasonex, which is specifically formulated for nasal use.

C) desloratadine
Desloratadine is an antihistamine used to relieve allergy symptoms such as runny nose and sneezing. Unlike mometasone furoate, it does not have the same anti-inflammatory properties and is not related to Nasonex.

D) fluticasone
Fluticasone is also a corticosteroid, but it is marketed under different brand names, such as Flonase. While both fluticasone and mometasone furoate are used for nasal allergy symptoms, fluticasone is not the generic name for Nasonex.

Conclusion
Mometasone furoate stands as the generic name for Nasonex, distinguishing it from other corticosteroids and antihistamines. Understanding the active ingredient is crucial for identifying the medication's uses and effects, particularly in treating allergic conditions. This knowledge helps ensure proper medication management and enhances patient care in allergy treatment.

Question 2

A pharmacy technician opens a sealed stock bottle of amlodipine 5 mg tablets and notices that many of the tablets have crumbled into smaller pieces. This is most likely due to:

Your Answer: Option(s)

Correct Answer: Option(s) C

Rationale

Physical instability is the most likely cause of the amlodipine tablets crumbling into smaller pieces.

Physical instability refers to changes in the physical properties of a drug formulation that can lead to degradation, such as crumbling or breaking apart. This can occur due to factors like moisture, temperature fluctuations, or mechanical stress during handling or transportation.

A) Photosensitivity
Photosensitivity occurs when a drug is sensitive to light, potentially leading to chemical degradation or loss of potency when exposed to light sources. However, photosensitivity typically does not cause physical crumbling of tablets, which is more related to the mechanical stability of the formulation rather than its chemical integrity.

B) Microbial contamination
Microbial contamination refers to the presence of harmful microorganisms that can lead to spoilage or degradation of pharmaceutical products. While this can affect drug safety and efficacy, it is unlikely to result in the crumbling of solid dosage forms like tablets, which are generally designed to resist microbial growth unless moisture or physical damage has occurred.

C) Physical instability
Physical instability encompasses various factors that can lead to the breakdown of the tablet structure, such as improper storage conditions or formulation issues. The crumbling observed in the amlodipine tablets suggests that they have experienced conditions that compromised their structural integrity, making this the most plausible explanation for the observation.

D) Correct storage
Correct storage refers to maintaining the recommended conditions for a drug to ensure its stability and efficacy. If the tablets are crumbling, it indicates that they have not been stored correctly or have been subjected to conditions that exceed their stability limits, thus this option does not apply to the situation described.

Conclusion
The crumbling of amlodipine 5 mg tablets is most likely due to physical instability, pointing to issues with the tablet formulation or environmental conditions that have affected their structural integrity. Understanding the reasons for such instability is crucial for ensuring the longevity and safety of pharmaceutical products, which rely on maintaining their physical and chemical properties throughout their shelf life.

Question 3

Which of the following auxiliary labels would be most appropriate to affix to a bottle of cephalexin oral suspension after reconstitution?

Your Answer: Option(s)

Correct Answer: Option(s) D

Rationale

Keep refrigerated; Discard after 14 days.

Cephalexin oral suspension, once reconstituted, should be stored in a refrigerator and used within 14 days to ensure its efficacy and safety. This ensures the medication remains effective while preventing degradation that could occur at room temperature.

A) Protect from light; Discard after 7 days
While protecting from light is important for some medications, cephalexin does not specifically require this precaution. Additionally, the recommended discard time after reconstitution is longer than 7 days, making this option incorrect.

B) Protect from light; Discard after 14 days
Though the discard time of 14 days is accurate, cephalexin oral suspension does not necessitate protection from light. Therefore, this option is partially correct but still unsuitable due to the incorrect auxiliary label.

C) Keep refrigerated; Discard after 7 days
This choice correctly states that the suspension should be kept refrigerated; however, the discard timeframe is incorrect. The correct duration after reconstitution is 14 days, not 7, which makes this option inaccurate.

D) Keep refrigerated; Discard after 14 days
This option accurately reflects the proper storage conditions for the reconstituted cephalexin oral suspension, requiring refrigeration and a discard period of 14 days, thus ensuring the medication remains effective and safe for use within that timeframe.

Conclusion
The correct labeling for reconstituted cephalexin oral suspension is crucial for patient safety and medication efficacy. It should be kept refrigerated and discarded after 14 days to prevent degradation. Understanding the specific storage requirements and discard × for medications helps in maintaining their effectiveness and ensures patient adherence to treatment regimens.

Question 4

How much menthol is required to compound a formula reading: 'camphor 0.3%, menthol 0.25%, hydrocortisone 1%, Aquaphor q.s. ad 600 g'?

Your Answer: Option(s)

Correct Answer: Option(s) C

Rationale

1500 mg of menthol is required to compound the formula.

To determine the amount of menthol needed in the formula, we calculate 0.25% of the total weight of the compounded formula, which is 600 g. This calculation results in 1500 mg of menthol.

A) 15 mg
This choice underestimates the required amount of menthol. To find 0.25% of 600 g, which is 1.5 g or 1500 mg, is significantly higher than 15 mg. Therefore, this option does not meet the criteria set by the formula.

B) 150 mg
While this choice is closer than option A, it still does not reflect the correct calculation for 0.25% of 600 g. The correct calculation yields 1500 mg, meaning 150 mg is only 10% of the required amount, making this choice incorrect.

C) 1500 mg
Calculating 0.25% of 600 g gives us 1.5 g, which converts to 1500 mg. This is indeed the precise amount of menthol needed as per the formula specifications, confirming this option as correct.

D) 15 g
This option significantly overestimates the needed amount of menthol. Since 15 g converts to 15000 mg, it far exceeds the calculated requirement of 1500 mg. Hence, this choice is not valid for the given formulation.

Conclusion
To accurately compound the formula specified, the amount of menthol required is determined by calculating 0.25% of 600 g, resulting in 1500 mg. This ensures the formulation meets the required concentrations of its components, while all other options either underestimate or overestimate the necessary amount of menthol. Proper calculations are essential in pharmaceutical formulations to guarantee efficacy and safety.

Question 5

A prescription for acetaminophen 325 mg tablets was inadvertently filled with acetaminophen 500 mg tablets, but the verifying pharmacist caught and corrected the mistake prior to dispensing. It would be most appropriate to report this situation as a(n):

Your Answer: Option(s)

Correct Answer: Option(s) A

Rationale

A near miss.

This situation qualifies as a near miss because the error was identified and corrected before any harm could occur to the patient. Reporting it as a near miss allows the pharmacy to analyze the incident and implement preventive measures for the future.

A) near miss
A near miss refers to an event that could have resulted in harm but was caught before any actual harm occurred. In this case, the pharmacist's intervention prevented the patient from receiving the incorrect dosage of acetaminophen, making it a prime example of a near miss that should be reported for quality improvement.

B) adverse drug reaction
An adverse drug reaction involves harmful or unintended responses to a medication after it has been administered. Since the error was caught before the medication was dispensed, no patient experienced any adverse effects, making this choice inappropriate for the scenario.

C) drug allergy
A drug allergy is an immune response to a medication that can cause various symptoms, ranging from mild to severe. In this case, there was no indication that the patient had an allergic reaction, nor was the medication administered, so this option does not apply to the situation described.

D) sentinel event
A sentinel event is a serious incident that results in death, permanent harm, or severe temporary harm. Since the pharmacist corrected the error before it could cause any harm, this situation does not meet the definition of a sentinel event.

Conclusion
The incident where a prescription was filled with the wrong dosage of acetaminophen but caught before dispensing is best categorized as a near miss. This classification highlights the importance of reporting and analyzing such events to enhance patient safety and prevent future occurrences. By addressing near misses, healthcare providers can improve their systems and processes, ultimately ensuring better outcomes for patients.
