What NCLEX Expects You To Do

  • Assess IV site regularly for pain, swelling, redness, coolness, leaking, or warmth.
  • Stop an infusion when infiltration or serious complications are suspected according to policy.
  • Recognize fluid overload cues such as crackles, dyspnea, edema, and rising blood pressure.
  • Verify compatibility and rate before administering IV medications.

High-Yield Quick Facts

QF-5-1

Infiltration often presents with swelling, coolness, pallor, discomfort, and slowed infusion.

QF-5-2

Phlebitis often presents with warmth, redness, tenderness, and a palpable cord.

QF-5-3

Fluid overload can cause crackles, dyspnea, edema, and increased blood pressure.

QF-5-4

Use an infusion pump for medications requiring precise control.

QF-5-5

Never ignore patient reports of burning or pain at the IV site.

Common NCLEX Traps

  • Slowing the IV but leaving an infiltrated catheter in place.
  • Charting redness without acting on phlebitis.
  • Focusing on the bag volume while the patient is short of breath.

Priority Nursing Actions

  • Stop the infusion and assess the site when infiltration is suspected.
  • Elevate extremity and follow policy for warm/cold compress based on fluid/medication.
  • Assess lung sounds and notify provider for suspected overload.

Safety

  • Vesicant infiltration can cause tissue injury.
  • Fluid overload is more dangerous for older adults and patients with cardiac or renal disease.

Medication Notes

  • Check compatibility before mixing medications or fluids.
  • High-alert IV medications need independent checks per policy.

Labs & Assessment

  • Monitor electrolytes and renal function when IV fluids or electrolyte replacements are used.
  • Strict intake and output helps evaluate fluid balance.

Take Topic Quiz
MCQ A nurse is reviewing care for a client with IV Therapy. Which finding or action best reflects safe NCLEX priority thinking?

A. Stop the infusion and assess the site when infiltration is suspected.

B. Slowing the IV but leaving an infiltrated catheter in place.

C. Delay assessment until all routine teaching is complete.

D. Focus only on memorizing the diagnosis name without reassessing the patient.

Correct answer: A
Rationale: Option A is correct because it connects the topic to immediate nursing judgment, patient safety, and reassessment. NCLEX questions usually reward the action that addresses the most relevant cue and reduces risk first.

SATA The nurse is teaching a student about IV Therapy. Which statements should be included? Select all that apply.

A. Infiltration often presents with swelling, coolness, pallor, discomfort, and slowed infusion.

B. Stop the infusion and assess the site when infiltration is suspected.

C. Vesicant infiltration can cause tissue injury.

D. Slowing the IV but leaving an infiltrated catheter in place.

E. Monitor electrolytes and renal function when IV fluids or electrolyte replacements are used.

F. Assessment findings are not needed when a topic is already familiar.

Correct answer: A,B,C,E
Rationale: A, B, C, and E are correct because they combine high-yield facts, priority nursing action, safety risk, and assessment or lab cues. SATA items often test whether the student can keep several safe ideas in mind at once.

NGN Based on the case, which response best shows Next Gen NCLEX clinical judgment?

A. Recognize the abnormal cue, connect it to the likely problem, choose the safest first action, and reassess the outcome.

B. Select the first familiar fact from memory and move to the next question.

C. Ignore the trend because one value or symptom rarely changes priority.

D. Provide broad teaching before deciding whether the patient is stable.

Correct answer: A
Rationale: The NGN case requires the full clinical judgment chain: recognize cues, analyze meaning, prioritize the likely problem, generate a solution, take action, and evaluate the response. This is exactly why quick facts should be paired with readiness assessment.
