1 kilogram (kg) is equal to how many pounds (lbs)?
1 lb
22 lbs
0.22 lbs
2.2 lbs
The Correct Answer is D
A. 1 lb.: One pound is significantly less than one kilogram, as 1 lb equals approximately 0.45 kg. Using this conversion would result in underestimating a client’s weight, leading to potential medication dosing errors.
B. 22 lbs.: This value is far too high; 22 lbs equals roughly 10 kilograms. Such a miscalculation would cause a serious overdose if medication doses were calculated based on weight.
C. 0.22 lbs.: This figure underestimates the conversion by a factor of ten. One kilogram is much heavier than 0.22 lbs, and using this value could lead to dangerous underdosing of weight-based medications.
D. 2.2 lbs.: One kilogram equals 2.2 pounds, which is the correct conversion. This standard ratio is essential for accurate medication calculations, particularly in pediatrics and clinical settings where weight-based dosing is required.

Correct Answer is D
Explanation
A. Demerol (meperidine HCL) 50 mg, IM, prior to surgery.: This order specifies administration before surgery, which serves as its clear endpoint. It is a single preoperative dose and therefore has a defined termination point.
B. Mevacor (lovastatin) 10 mg, po, every 12 hours for 7 days.: The inclusion of “for 7 days” provides a definite duration, meaning the order will automatically terminate after the specified treatment period ends.
C. Lasix (furosemide) 40 mg, IV, STAT.: A STAT order is intended for immediate, one-time administration, so it has an inherent termination after that single dose is given.
D. Motrin (ibuprofen) 400 mg, po, daily.: This order does not specify a stop date or duration of therapy, meaning it would continue indefinitely until changed or discontinued by the provider. It is therefore written without a termination.
Correct Answer is A
Explanation
A. Call the physician and have the order clarified: Ambiguous or unclear medication orders must always be clarified directly with the prescribing provider to prevent medication errors and ensure patient safety.
B. Administer the medication twice a day and as needed: Giving medication without clarification risks overdose or underdose due to unclear dose range.
C. Talk to the unit secretary on the floor who is good at reading the physician's handwriting: Only the prescriber can legally clarify or change an order, not clerical staff.
D. Consult a pharmacist to interpret the order: While pharmacists can offer guidance, they cannot confirm intent; the prescriber must clarify the specific dose and frequency.
