What is the primary purpose of administering a large-volume IV bolus?
To provide additional electrolytes during imbalance correction.
To maintain normal blood pressure in hypertensive patients.
To rapidly replace fluid loss due to dehydration or trauma.
To treat hypothermia by warming the body rapidly.
The Correct Answer is C
A. To provide additional electrolytes during imbalance correction: While IV fluids may contain electrolytes, bolus administration is not typically used to correct gradual electrolyte imbalances. Electrolyte replacement is usually done more slowly to avoid complications like hypernatremia or hyperkalemia.
B. To maintain normal blood pressure in hypertensive patients: Bolus IV fluids are not indicated for managing hypertension. Rapid fluid administration could worsen blood pressure control in these patients.
C. To rapidly replace fluid loss due to dehydration or trauma: A large-volume IV bolus delivers fluids quickly to restore intravascular volume, improve perfusion, and prevent shock. This intervention is essential in acute dehydration, hemorrhage, or trauma to stabilize hemodynamics.
D. To treat hypothermia by warming the body rapidly: Warming fluids may assist in hypothermia management, but the primary purpose of a bolus is volume expansion, not rapid temperature correction. Warming alone is addressed separately.

Correct Answer is C
Explanation
A. No identifiers are needed: Administering medication without verifying the client is unsafe and violates standard nursing practice. Omitting identifiers significantly increases the risk of medication errors and patient harm.
B. One identifier: Using only one identifier is insufficient to ensure accurate patient identification, as it may not reliably distinguish between clients with similar names or demographics. Safety standards require additional verification.
C. Two identifiers: Using two client identifiers—such as full name and date of birth, or medical record number—before medication administration is the standard of care. This practice reduces the risk of errors and ensures that medications are given to the correct client.
D. Three identifiers: While using three identifiers may add extra confirmation, current guidelines from The Joint Commission and most hospital policies recommend two identifiers as the required standard for safe medication administration.
Correct Answer is C
Explanation
A. QHS: This abbreviation stands for “every night at bedtime” and is used to indicate the timing of medication administration, not frequency on alternating days.
B. BID: BID means “twice a day” and specifies that the medication should be administered approximately every 12 hours. It does not indicate alternating day dosing.
C. QOD: QOD is the standard abbreviation for “every other day,” indicating that the medication should be given on alternating days. This abbreviation is commonly used in outpatient and inpatient orders to simplify scheduling.
D. TID: TID stands for “three times a day,” usually spaced about every 8 hours, and does not reflect an every-other-day schedule.
