The CE Shop Realestate Pennsylvania Exam Answers

Question 1

What volume, in tsp, of a 20 mEq/15 mL solution would deliver a dose of 40 mEq?

Your Answer: Option(s)

Correct Answer: Option(s) B

Rationale

6 tsp of a 20 mEq/15 mL solution would deliver a dose of 40 mEq.

To determine the volume required to deliver a specific dose, you can use the concentration of the solution. The solution has a concentration of 20 mEq per 15 mL, which translates to a need for 6 tsp to achieve a total of 40 mEq.

A) 2
Choosing 2 tsp would only deliver a fraction of the required dose. Since 20 mEq is present in 15 mL (which is approximately 3 tsp), 2 tsp would yield less than 20 mEq, making it insufficient for a 40 mEq dose.

B) 6
This is the correct choice, as 6 tsp corresponds to the required 40 mEq. With the concentration of 20 mEq per 15 mL, you can calculate that 6 tsp (or 30 mL) contains 40 mEq, thus satisfying the dosage requirement.

C) 30
30 tsp is an excessive volume that would far exceed the 40 mEq needed. At the concentration of 20 mEq per 15 mL, 30 tsp would deliver significantly more than 40 mEq, which is unnecessary and impractical for the dosage.

D) 40
40 tsp would also deliver significantly more than the desired 40 mEq. At the concentration provided, this volume is impractical and would lead to an overdose, as it would yield a much higher mEq than required.

Conclusion
To achieve a dose of 40 mEq from a 20 mEq/15 mL solution, one must calculate the required volume in teaspoons. The correct volume is 6 tsp, which aligns perfectly with the dosage needed, avoiding both underdose and overdose scenarios. Understanding the relationship between concentration and volume is crucial in ensuring accurate medication delivery.

Question 2

According to USP Chapter 800, gowns worn during the preparation of hazardous nonsterile compounds must:

Your Answer: Option(s)

Correct Answer: Option(s) B

Rationale

Gowns worn during the preparation of hazardous nonsterile compounds must be selected based on the specific hazardous drugs being handled.

Selecting gowns according to the specific hazardous drugs ensures adequate protection for personnel by matching the gown's properties with the risks associated with the drugs being handled.

A) have seams or closures that could allow hazardous drugs to reach the skin
This choice is incorrect because gowns must be designed to prevent any hazardous drugs from reaching the skin. Seams and closures that allow for such exposure would violate safety protocols outlined in USP Chapter 800.

C) be made of reusable material to absorb hazardous drug residue
While gowns can be made of reusable materials, the focus should be on their protective capabilities rather than their absorbency. Gowns should be made of materials that prevent permeation by hazardous drugs, not necessarily those that absorb residues. Using non-permeable materials is critical for safety.

D) have short sleeves and open cuffs to minimize hazardous drug exposure
This choice is incorrect as short sleeves and open cuffs would actually increase the risk of exposure to hazardous drugs. USP Chapter 800 recommends gowns with long sleeves and closed cuffs to provide better protection against exposure during the preparation of hazardous compounds.

Conclusion
Gowns are a critical component of personal protective equipment when handling hazardous nonsterile compounds. According to USP Chapter 800, their selection must be tailored to the specific hazardous drugs being handled to ensure maximum safety and minimize exposure risks. Incorrect choices emphasize features that could compromise safety, highlighting the importance of rigorous adherence to protective guidelines in pharmaceutical practice.

Question 3

A pharmacy technician receives an order for azithromycin 200 mg/5 mL PO daily. What dosage form should be dispensed?

Your Answer: Option(s)

Correct Answer: Option(s) C

Rationale

The dosage form that should be dispensed is a suspension.

Azithromycin 200 mg/5 mL is a liquid formulation typically used for oral administration, which indicates that a suspension is the most appropriate dosage form for this prescription.

A) Tablet
Tablets are solid dosage forms that require swallowing whole and are typically not appropriate for those who may have difficulty swallowing, such as children. Since the prescribed azithromycin is in a liquid form (200 mg/5 mL), a tablet would not match the required dosage form.

B) Capsule
Capsules, like tablets, are solid dosage forms that contain the medication in a gelatin shell. While capsules can sometimes be opened and mixed with liquids, the order specifies a liquid dosage form (200 mg/5 mL), making a capsule unsuitable for this prescription.

C) Suspension
Suspensions are liquid dosage forms where the active ingredient is dispersed throughout a liquid medium, allowing for easy administration. The prescription for azithromycin at 200 mg/5 mL explicitly indicates a liquid formulation, confirming that a suspension is the correct choice.

D) Suppository
Suppositories are solid forms of medication intended for insertion into the rectum, where they dissolve and are absorbed. This dosage form does not align with the oral administration specified in the order (PO), thus making it an inappropriate choice for dispensing azithromycin.

Conclusion
In summary, the order specifies azithromycin in a liquid form at a dosage of 200 mg/5 mL for oral use, which necessitates dispensing a suspension. Solid dosage forms such as tablets, capsules, and suppositories do not fulfill the requirement for this specific medication and administration route. Therefore, a suspension is the appropriate and effective choice for this prescription.

Question 4

Following reconstitution, Varivax should be administered within a maximum of:

Your Answer: Option(s)

Correct Answer: Option(s) A

Rationale

Varivax should be administered within a maximum of 30 minutes following reconstitution.

Following the reconstitution of Varivax, it is crucial to administer the vaccine promptly within 30 minutes to ensure its effectiveness and stability. Delaying administration beyond this timeframe can compromise the vaccine's potency and safety.

A) 30 minutes
This is the correct answer as Varivax must be used immediately after reconstitution, ideally within 30 minutes, to maintain its efficacy. Administration beyond this period can reduce the vaccine's effectiveness due to potential degradation.

B) 48 hours
This choice is incorrect because administering Varivax 48 hours after reconstitution exceeds the recommended timeframe for effective use. The vaccine may lose its effectiveness if not used promptly, rendering it ineffective for immunization purposes.

C) 7 days
This option is also incorrect, as Varivax should not be administered 7 days after reconstitution. Such a delay would significantly increase the risk of the vaccine being ineffective, as the vaccine's components may degrade over time beyond the recommended 30-minute window.

D) 2 weeks
Choosing 2 weeks is incorrect since this timeframe is far too long for the administration of Varivax after reconstitution. Similar to the previous choices, waiting 2 weeks would likely lead to a complete loss of vaccine potency and efficacy.

Conclusion
In summary, Varivax must be administered within 30 minutes of reconstitution to ensure its effectiveness. Delays beyond this period, even up to 48 hours or more, can lead to a loss of potency, making timely administration essential for successful immunization. This strict guideline underscores the importance of proper vaccine handling and administration protocols in clinical practice.

Question 5

A prescription calls for one capsule of a medication to be administered PO a.c. daily for 14 days. What directions should appear on the label?

Your Answer: Option(s)

Correct Answer: Option(s) C

Rationale

Take one capsule by mouth before a meal once daily for 14 days.

The prescription specifies "PO a.c.," indicating the medication should be taken by mouth (PO) before meals (a.c., or "ante cibum"). This instruction is essential for ensuring the medication's effectiveness and minimizing potential gastrointestinal side effects.

A) Take one capsule by mouth daily for 14 days
This option correctly states the dosage and duration but omits the critical detail regarding timing in relation to meals. Without the specification that the capsule should be taken before meals, this instruction may lead to improper administration and could affect the medication's efficacy.

B) Take one capsule by mouth after a meal once daily for 14 days
This choice completely contradicts the prescription's instructions. Taking the medication after a meal rather than before can significantly alter its absorption and effectiveness, potentially leading to reduced therapeutic outcomes or increased side effects.

C) Take one capsule by mouth before a meal once daily for 14 days
This option accurately reflects the prescription's requirements. It explicitly states that the capsule should be taken before meals, which is critical for the intended effects of the medication. Adhering to this instruction ensures optimal absorption and therapeutic efficacy.

D) Take one capsule by mouth with a meal once daily for 14 days
Like option B, this choice misinterprets the timing of the medication. Taking it with a meal rather than before can interfere with the absorption rate of the medication, potentially compromising its effectiveness and leading to unintended side effects.

Conclusion
The prescription clearly indicates that the medication must be taken before meals, as denoted by "PO a.c." This specificity is vital for ensuring the proper administration and therapeutic effect of the medication. Options A, B, and D fail to adhere to this requirement, highlighting the importance of precise language in medication instructions to prevent misadministration and to ensure patient safety.
