How can the nurse determine a patient's history of allergies? (Select all that apply.)

A) Only administer 40 mg: This option is not appropriate without consulting the healthcare provider. Simply administering a smaller dose without confirming the rationale behind the prescribed 120 mg could result in inadequate treatment for the patient.

B) Use at least two patient identifiers whenever administering a medication: Utilizing two patient identifiers (such as name and date of birth) is essential to ensure that the medication is administered to the correct patient. This step is a key practice in medication safety to prevent errors.

C) Read labels at least two times to make sure it is the correct medication: Carefully reading labels at least twice helps confirm that the nurse is administering the correct medication and dosage. This practice reduces the risk of errors and ensures that the right drug is given.

D) Double-check all calculations: Verifying calculations is critical, especially when dealing with high doses or unusual orders. This step ensures accuracy in the dosage administered and helps prevent medication errors that could lead to toxicity or ineffective treatment.

E) Question unusually large or small doses: It is essential to question any dosage that appears significantly outside the usual range, such as the prescribed 120 mg of Lasix, which exceeds the standard dosing guidelines. Consulting with the healthcare provider for clarification is crucial in such cases to ensure patient safety.

A) Three times a day: This option suggests administering medication at intervals that would total three doses in a 24-hour period. However, "BID" specifically refers to taking a medication twice a day, typically at evenly spaced intervals.

B) Twice a day: The abbreviation "BID" stands for "bis in die," which is Latin for "twice a day." This means that the patient will receive the medication two times within a 24-hour period, often recommended to maintain consistent therapeutic levels.

C) After meals: While some medications are taken after meals for better absorption or to minimize gastrointestinal side effects, the term "BID" does not specify timing relative to meals. Therefore, this option does not accurately describe the frequency of administration.

D) Four times a day: This option indicates administering medication four times within a 24-hour period, which would be represented by the abbreviation "QID" (quater in die) rather than "BID." Thus, it does not align with the definition of taking medication twice daily.
