The nurse is receiving the shift report for four clients on a progressive care step-down unit. Which client should the nurse assess FIRST?

  1. A client 48 hours post-myocardial infarction who reports mild agitation, has a blood pressure of 102/86 mm Hg, and a newly auscultated holosystolic murmur at the apexCevap
  2. B
    A client with end-stage renal disease who missed hemodialysis, exhibits Kussmaul respirations, and has an arterial blood gas of pH 7.29, PaCO2 31 mm Hg, and HCO3 14 mEq/L
  3. C
    A client receiving an intravenous vancomycin infusion who develops sudden intense facial erythema, a heart rate of 106 bpm, and a blood pressure of 110/64 mm Hg
  4. D
    A client 18 hours post-craniotomy who reports a dull headache, has a heart rate of 62 bpm, a respiratory rate of 16 breaths/min, and a blood pressure of 138/84 mm Hg

Cevap

The client who is 48 hours post-myocardial infarction with a blood pressure of 102/86 mm Hg and a new holosystolic murmur
The client who is 48 hours post-myocardial infarction is exhibiting early signs of acute papillary muscle rupture, a catastrophic mechanical complication. The newly auscultated holosystolic murmur indicates severe, acute mitral regurgitation. The exceedingly narrow pulse pressure of 16 mm Hg (102 - 86) combined with mild agitation are compensatory sympathetic responses to rapidly plummeting cardiac output. This client is in impending cardiogenic shock and requires immediate echocardiography, hemodynamic support, and emergency surgical intervention to survive.

Adım Adım Çözüm

1
Analyze the clinical data for the post-myocardial infarction client.
The client has a new holosystolic murmur, mild agitation, and a severely narrowed pulse pressure of 16 mm Hg (102 - 86).
A new murmur post-MI strongly suggests a mechanical complication like papillary muscle rupture. The narrow pulse pressure indicates severe compensatory vasoconstriction due to plummeting cardiac output.
2
Evaluate the arterial blood gas values for the client with end-stage renal disease.
pH is 7.29 (acidosis), HCO3 is 14 mEq/L (metabolic cause), and PaCO2 is 31 mm Hg (respiratory compensation).
This is a predicted physiological adaptation (metabolic acidosis with partial respiratory compensation) for missed dialysis, making it less acutely life-threatening than a mechanical cardiac failure.
3
Assess the symptoms of the client receiving vancomycin.
Facial erythema and mild tachycardia with a stable blood pressure (110/64 mm Hg).
These are classic signs of Red Man syndrome, a non-allergic histamine release that is managed simply by slowing the infusion, rather than a true anaphylactic shock.
4
Review the vital signs for the post-craniotomy client.
Heart rate is 62 bpm, respiratory rate is 16, and blood pressure is 138/84 mm Hg.
These findings do not constitute Cushing's triad (widening pulse pressure, bradycardia, irregular respirations), meaning a life-threatening increase in intracranial pressure is not currently evident.
5
Prioritize the clients based on the immediate risk to life.
The post-MI client is entering rapidly fatal cardiogenic shock and requires immediate life-saving intervention.
Acute papillary muscle rupture is a critical emergency that will swiftly progress to cardiovascular collapse without immediate hemodynamic support and surgery.
