1mL is equal to how many drops (gtts)?

A. 2.0 mg: Writing a trailing zero before the decimal point can cause a tenfold overdose if the decimal is missed or misread. This is a high-risk notation and is not recommended for safety.

B. 0.2 mg: Leading zeros before a decimal point are required for doses less than one to prevent misinterpretation. “0.2 mg” clearly indicates two-tenths of a milligram and minimizes the risk of a tenfold dosing error.

C. 0.20 mg: Although technically correct, the extra zero may be unnecessary and could be misinterpreted in some handwritten contexts. The standard safe practice emphasizes clarity and minimal ambiguity, which “0.2 mg” provides.

D. 2 mg: This represents two milligrams, not two-tenths of a milligram. Using this notation would result in a tenfold overdose if intended as 0.2 mg.

A. The chest x-ray should be performed after obtaining consent from the patient's family: While consent may be required for certain procedures, a STAT order indicates urgency and does not delay care for nonemergent consent in standard imaging. Family consent is not a prerequisite in emergency or urgent situations.

B. The chest x-ray should be performed within the next 24 hours: Orders with a 24-hour timeframe are typically labeled as “routine” or “PRN,” not STAT. Waiting up to 24 hours does not meet the urgency implied by STAT.

C. The chest x-ray should be performed during the patient's next scheduled radiology appointment: Scheduling for a routine appointment would delay urgent diagnostic information. STAT orders bypass standard scheduling to prioritize immediate evaluation.

D. The chest x-ray should be performed immediately: STAT indicates that the procedure must be done without delay to assess or address an acute change in the patient’s condition. Immediate performance ensures timely diagnosis and intervention, aligning with the urgency of the order.
