Provision of Care and Clinical Interventions
From Plan to Action
Provision of care translates the care plan into safe, evidence-informed interventions. Know the rationale for each intervention, the expected outcome, and the parameters that require you to stop or escalate. Interventions cluster into physiologic support (oxygen therapy, positioning, hydration, nutrition, mobility), psychosocial support, and education.
Technical Competence
Candidates should understand principles behind common procedures: aseptic technique for invasive access, correct positioning to protect airway and skin, oxygen delivery devices and their approximate fraction of inspired oxygen, and the difference between interventions that require a prescription and independent nursing actions (repositioning, comfort measures, hygiene, safety).
Evaluation
Every intervention needs evaluation: did the pain score fall, did the oxygen saturation rise, did the wound edges approximate? Document the response, not just the act.
Traps
Question writers love interventions that are correct in isolation but wrong in sequence - for example, mobilizing a patient before assessing orthostatic risk, or giving a full meal before confirming swallow safety. Another trap is choosing a task outside scope of practice or one that requires a new order. Watch for "which action should the nurse take next" versus "first" - next follows the current step, first precedes everything.
Worked Example
A postoperative patient reports sudden calf pain and swelling. Massaging the calf is a plausible comfort intervention but is contraindicated because it may dislodge a thrombus. The correct response is to keep the patient still, notify the provider, and anticipate imaging and anticoagulation. The rule: when a new finding could represent a serious complication, immobilize, assess, and escalate rather than treat symptomatically.
