Key ideas to know
Start with the relationships between ideas. Then close the notes and explain each one from memory.
- 01
Medication administration requires verification of the client, medication, dose, route, time, indication, allergies, and required assessment.
- 02
A nurse checks current findings and relevant laboratory results before giving medicines with hold parameters.
- 03
Medication reconciliation compares the current regimen across admission, transfer, and discharge.
- 04
High-alert medicines require added safeguards because errors can cause severe harm.
- 05
An adverse drug reaction is an unintended harmful response at a usual dose.
- 06
Intravenous therapy requires assessment of the site, prescribed fluid, rate, compatibility, and client response.
- 07
Parenteral nutrition requires glucose monitoring and careful line care according to policy.
- 08
Client teaching includes purpose, schedule, administration, common effects, danger signs, and when to contact a clinician.

7Why are infusion pumps used?Show answer ＋
To control fluid or medicine delivery at a programmed rate.
8What information belongs in medication teaching?Show answer ＋

Explain it in your own words
Use the answer as a check after you have written or spoken your response.
01A client's pulse is below a prescribed hold parameter before a cardiac medicine. What should the nurse do?
Hold the dose, reassess, review the prescription, and contact the prescriber according to policy.
02Why should two intravenous medicines be checked for compatibility?
Incompatible medicines can precipitate, lose activity, or cause harm when mixed in the same line.
03A client develops facial swelling and breathing difficulty after a new medicine. What comes first?
Stop the medicine when applicable, address airway and breathing, call for emergency assistance, and follow the emergency protocol.
04Why is abrupt interruption of parenteral nutrition a concern?
Its high glucose delivery can lead to rapid blood-glucose shifts, so interruption requires prompt assessment and prescribed management.
05How does teach-back test medication teaching?
The client explains or demonstrates the plan in their own words, allowing the nurse to find and correct gaps.
