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. I will ensure the tablet is the same color as the tablets the client takes at home.: Tablet color can vary between manufacturers, even for the same medication and dosage. Relying on color for verification is unsafe and can lead to medication errors; nurses must always verify the label and order instead.
B. I will only ask the client's name to verify I have the right client.: Using only the client’s name fails to meet the safety standard for patient identification. At least two identifiers, such as name and date of birth or medical record number, must be used to ensure accurate patient verification.
C. I will give HS medications each morning.: HS stands for “at bedtime,” so giving such medications in the morning represents a timing error. Administering medications at the wrong time can reduce therapeutic effectiveness or cause unintended side effects.
D. I will be sure to check for the right dose of medication.: Checking the correct dosage is one of the essential “rights” of medication administration. Verifying the dose helps prevent underdosing or overdosing and ensures safe and effective therapeutic outcomes for the client.
Correct Answer is C
Explanation
A. Having up-to-date knowledge about medications.: Nurses must maintain current knowledge of pharmacologic principles, including indications, contraindications, side effects, and interactions, to ensure safe and effective medication administration.
B. Administering medications.: Administering medications is a core nursing responsibility in the acute care setting. The nurse ensures the right drug, dose, route, time, and patient, while also monitoring for therapeutic effects and adverse reactions.
C. Prescribing medications.: Nurses generally do not prescribe medications unless they hold advanced practice roles with prescriptive authority, such as nurse practitioners. In most settings, prescribing is the responsibility of physicians or qualified prescribers.
D. Preparing medications.: Preparing medications accurately is part of the nurse’s role to ensure proper dosing and prevent administration errors. This includes verifying orders, calculating doses, and maintaining aseptic technique during preparation.
