Update | Graded A+
Question 1
A healthcare provider gives a verbal medication order to a nurse during a
busy shift. The nurse is uncertain whether the medication dose was 0.5 mg or
5 mg. What is the BEST action?
A. Administer 0.5 mg because it is the safer dose
B. Administer 5 mg because the provider probably intended the therapeutic
dose
C. Clarify the order with the prescribing provider before administering the
medication
D. Ask another nurse to choose the appropriate dose
Correct Answer: C
Explanation:
An ambiguous medication order should never be interpreted by guessing. The
nurse should clarify the order with the authorized prescriber and confirm the
medication, dose, route, frequency, and other relevant elements before
administration. Selecting a dose independently creates a significant
medication-safety risk.
Question 2
A nurse receives a telephone order from a provider. Which action provides the
BEST verification of the order?
A. Document the order from memory after ending the call
B. Repeat the order back to the provider for confirmation
C. Ask another nurse what the provider usually orders
D. Wait until the next shift to document it
Correct Answer: B
1
,Explanation:
Read-back or repeat-back is an important safety practice for verbal and
telephone orders. The nurse repeats the order to the provider, allowing errors
involving medication name, dose, route, frequency, or other instructions to be
identified immediately.
Question 3
A provider writes an order that reads: “MS 4 mg IV now.” What is the nurse's
PRIMARY concern?
A. The order does not specify the patient's room number
B. The abbreviation “MS” may be ambiguous
C. IV medications never require clarification
D. The dose is automatically incorrect
Correct Answer: B
Explanation:
Ambiguous abbreviations can result in serious medication errors. The nurse
should clarify the intended medication rather than assuming that “MS” means
morphine or another medication. Medication orders should be clear,
complete, and unambiguous.
Question 4
A nurse receives an order to administer a medication “PRN for pain.” Which
additional information is MOST important before implementing the order?
A. The provider's preferred pharmacy
B. The specific indication, dose, route, and frequency or minimum interval
C. The patient's insurance provider
D. The date of the patient's previous admission
Correct Answer: B
2
,Explanation:
A PRN order must provide sufficient information for safe administration. The
nurse needs to know what the medication is being used for, the dose, route,
and when it may be repeated. An incomplete PRN order should be clarified
before administration.
Question 5
A nurse transcribes a new medication order into the medication
administration record and notices that the prescribed dose differs
substantially from the patient's previous dose. What should the nurse do
FIRST?
A. Change the new order to match the old dose
B. Administer the new dose because the provider wrote it
C. Verify the order and clarify the discrepancy when necessary
D. Delete the old medication history
Correct Answer: C
Explanation:
A significant dose change may be intentional, but it could also represent a
prescribing or transcription error. The nurse should compare the order with
available clinical information and clarify the discrepancy through the
appropriate process before administering an unsafe or questionable dose.
Question 6
Which characteristic BEST describes a complete medication order?
A. Medication name only
B. Medication name, dose, route, frequency, and other required instructions
C. Medication name and room number
D. Medication name and patient's diagnosis only
Correct Answer: B
3
, Explanation:
A complete order contains sufficient information for safe implementation.
Depending on the medication and institution, this may include the medication
name, dose, route, frequency, indication, duration, parameters, and other
necessary instructions.
Question 7
A provider gives a verbal order while the nurse is simultaneously receiving
another emergency communication. What is the safest approach?
A. Try to remember the order and enter it later
B. Ask the provider to repeat the order and use read-back verification
C. Ask a nursing assistant to interpret the order
D. Administer the medication based on the portion remembered
Correct Answer: B
Explanation:
Interruptions and competing tasks increase the risk of transcription errors.
The nurse should obtain the complete order, repeat it back, and ensure that all
critical elements are accurately understood and documented.
Question 8
A medication order states: “Give insulin per sliding scale.” No sliding-scale
protocol or parameters are attached or otherwise available. What should the
nurse do?
A. Estimate the dose based on the patient's glucose level
B. Use a previous patient's sliding scale
C. Clarify the order and obtain the specific parameters
D. Automatically administer the lowest dose
Correct Answer: C
