Zorluk: OrtaPhysiological Adaptation

A nurse is caring for a client who is receiving an intravenous infusion of ceftriaxone for a severe infection. Ten minutes into the infusion, the client suddenly reports throat tightness, severe dizziness, and develops visible facial swelling. Arrange the following nursing actions in the correct order of priority.

  1. 1Stop the intravenous antibiotic infusion.
  2. 2Assess airway patency and apply high-flow oxygen.
  3. 3Administer intramuscular epinephrine.
  4. 4Initiate a rapid bolus of 0.9% sodium chloride.
  5. 5Administer intravenous diphenhydramine.

Cevap

Stop the infusion, assess the airway and apply oxygen, administer intramuscular epinephrine, initiate an IV fluid bolus, and finally administer intravenous diphenhydramine.
The correct sequence relies on the core principles of emergency management: removing the offending agent, stabilizing the ABCs (Airway, Breathing, Circulation), and administering therapies in order of life-saving necessity. Stopping the antibiotic halts further antigen exposure. Immediately assessing the airway and oxygenating the client addresses the highest immediate risk (asphyxiation). Epinephrine is the definitive primary treatment for anaphylaxis to reverse respiratory and hemodynamic compromise. IV fluids then support circulation to correct distributive shock. Finally, adjunctive medications like diphenhydramine are given to manage non-life-threatening symptoms.

Adım Adım Çözüm

1
Remove the triggering stimulus.
The intravenous ceftriaxone infusion is immediately discontinued.
Continuing the infusion will worsen the anaphylactic reaction and accelerate cardiovascular and respiratory collapse.
2
Prioritize Airway and Breathing.
Airway patency is assessed and high-flow oxygen is administered.
Anaphylaxis commonly causes laryngeal edema and bronchospasm, making airway protection the most critical physiological priority after removing the trigger.
3
Administer life-saving pharmacology.
Intramuscular epinephrine is injected.
Epinephrine provides rapid alpha- and beta-adrenergic stimulation to relieve airway obstruction and elevate blood pressure.
4
Support Circulation.
A rapid bolus of 0.9% sodium chloride is initiated.
Massive vasodilation leads to distributive shock and severe hypotension, requiring immediate intravascular volume expansion.
5
Provide adjunctive symptom management.
Intravenous diphenhydramine is administered.
H1 receptor antagonists alleviate peripheral symptoms like pruritus and urticaria, but they do not treat the primary life-threatening manifestations of anaphylaxis.
