High Alert LASA - Pharmacy Technician Certification Exam Ptce

1. In sterile compounding, insulin vials resemble another vial; how can technology prevent LASA errors in pharmacies?
   Answer: Barcode scan product and patient label This question tests the PTCE candidate's ability to identify high-alert medications and LASA risks, crucial for patient safety and quality assurance. High-alert medications are drugs that bear a heightened risk of causing significant harm if used incorrectly; LASA risks involve medications that are easily confused due to similar names or packaging. In the given scenario, barcode scanning is emphasized as a technological measure to prevent LASA errors with insulin vials in sterile compounding. The correct answer identifies an effective use of technology for LASA prevention, demonstrating an understanding of PTCE guidelines. A common distractor might suggest relying on visual cues like vial cap colors, reflecting a misunderstanding of the content. To help candidates, emphasize learning the specific characteristics and examples of high-alert and LASA medications, and practice scenario-based questions to apply these concepts accurately.
2. Which of the following pairs represents a brand and generic name for the same high-alert anticoagulant?
   Answer: Lovenox and enoxaparin Lovenox is the brand name for enoxaparin, a low-molecular-weight heparin, which is a high-alert medication due to bleeding risk. The other pairs are incorrect: Plavix (clopidogrel) and warfarin are different drugs (B, D), and heparin and dalteparin are different types of heparinoids (C).
3. A prescription for 'MS Contin' is processed. This medication is considered high-alert due to its active ingredient, morphine sulfate. What is the primary safety measure a technician should observe when handling this type of medication?
   Answer: Ensure it is not stored near look-alike packaging for magnesium sulfate. Morphine sulfate (MS) and magnesium sulfate (MgSO4) are a classic look-alike pair due to their abbreviations. A mix-up could be fatal, as magnesium sulfate is used for seizures or electrolyte replacement and has a vastly different dose. Verifying the dose (B) is always important, but the specific LASA risk with magnesium sulfate is a critical safety concern to address through storage strategies.
4. The use of 'Tall Man lettering' (e.g., buPROPion and busPIRone) is a safety strategy designed to reduce errors between which type of medications?
   Answer: Look-alike/sound-alike medications Tall Man lettering is an error-prevention strategy recommended by the FDA and ISMP to help differentiate the names of look-alike/sound-alike (LASA) drug pairs. It draws attention to the dissimilar parts of the names to prevent mix-ups during prescribing, transcribing, and dispensing.
5. According to the Institute for Safe Medication Practices (ISMP), which of the following medications is classified as a high-alert medication due to its narrow therapeutic index and high risk of causing significant patient harm if used in error?
   Answer: Warfarin Warfarin is an anticoagulant classified as a high-alert medication because errors in dosing can lead to severe bleeding or clotting events. Amoxicillin (antibiotic), loratadine (antihistamine), and ibuprofen (NSAID) have a wider margin of safety and are not on the ISMP list of high-alert medications for community pharmacy.
6. During IV prep, a technician selects potassium chloride concentrate; which of the following medications is considered high-alert?
   Answer: Potassium chloride concentrate This question tests the PTCE candidate's ability to identify high-alert medications and LASA risks, crucial for patient safety and quality assurance. High-alert medications are drugs that bear a heightened risk of causing significant harm if used incorrectly; LASA risks involve medications that are easily confused due to similar names or packaging. In the given scenario, potassium chloride concentrate is highlighted as a high-alert medication during IV preparation.

8. While the technician correctly identifies the allergy issue, which of the following high-alert medications also poses a significant risk of severe respiratory depression similar to codeine?
   Answer: Methadone Methadone, like codeine, is an opioid and high-alert medication that poses significant risk of life-threatening respiratory depression. While heparin (bleeding), insulin (hypoglycemia), and concentrated potassium chloride (cardiac arrest) are also high-alert medications, they do not share the respiratory depression risk profile of opioids.
9. Which entire class of medications is considered high-alert because of the risk of profound hypoglycemia if an incorrect product or dose is administered?
   Answer: Insulins Insulins are a major class of high-alert medications. Errors involving insulin, such as confusing long-acting and short-acting types (e.g., Lantus and Novolog), can lead to severe and potentially fatal hypoglycemia (low blood sugar).
10. A pharmacy receives a new prescription for hydralazine. Which of the following medications on the pharmacy shelf presents the most significant risk for a dispensing error due to its look-alike/sound-alike (LASA) name?
    Answer: Hydroxyzine Hydralazine (an antihypertensive) and hydroxyzine (an antihistamine/anxiolytic) are a well-known LASA pair. An error could lead to untreated hypertension or unintended sedation. The other options, while all starting with 'hydro-', are less phonetically and orthographically similar to hydralazine.
