A client is admitted to the intensive care unit (ICU) with increasing shortness of breath due to a pulmonary embolism (PE). Which finding should the nurse immediately report to the healthcare provider (HCP)?

Reference Range:

• Central venous pressure (CVP) [2 to 14 cm H2O]

Rationale:
A. Administer famotidine 20 mg IV: Famotidine is used for stress ulcer prophylaxis in critically ill clients but does not address the current protocol-driven abnormalities. The client’s immediate issues relate to glucose control, hemodynamics, and oxygenation.

B. Raise oxygen by 10 percent: The client’s oxygen saturation is 92% on 50% oxygen, which is acceptable in the setting of critical illness and MODS. There is no evidence of acute hypoxemia requiring escalation at this time. Oxygen therapy adjustments are not prioritized when saturation goals are being met.

C. Increase dopamine 2 mcg/kg/min: Dopamine is being titrated to maintain a MAP greater than 65 mm Hg, and the current MAP is 66 mm Hg, meeting the target. Increasing dopamine could unnecessarily raise heart rate and myocardial oxygen demand. No titration is indicated while the hemodynamic goal is achieved.

D. Titrate insulin infusion by 1 unit/hour: The blood glucose level of 160 mg/dL falls within the 150–199 mg/dL range, which requires an increase in insulin infusion by 1 unit/hour per protocol. Adjusting the insulin drip maintains tight glycemic control, which is essential in MODS to reduce infection risk and improve outcomes.

Rationale:

• Cardiogenic shock: The client presents with hypotension, tachycardia, altered mental status, cool clammy skin, oliguria, and severe hypoxia, all of which indicate inadequate tissue perfusion. Echocardiography confirms severe mitral regurgitation with ventricular dilation, leading to poor forward cardiac output. Elevated cardiac markers and atrial fibrillation with rapid ventricular response further compromise cardiac function.

• Heart failure (HF): Although the client has signs of heart failure, including dyspnea, edema, and crackles, the presence of hypotension and end-organ hypoperfusion indicates progression beyond simple heart failure. Cardiogenic shock represents a severe complication of heart failure with systemic consequences. The unstable vital signs and altered mental status support shock physiology. Therefore, heart failure alone does not fully explain the severity of findings.

• Myocardial infarction (MI): Elevated troponins suggest myocardial injury but do not confirm an acute MI as the primary condition. The clinical picture is dominated by pump failure rather than coronary occlusion. Severe mitral regurgitation and ventricular dilation explain the cardiogenic shock more directly. MI may be contributory but is not the primary condition.

• Hypertrophic cardiomyopathy (HCM): HCM typically presents with diastolic dysfunction, preserved systolic function, and a systolic murmur that increases with decreased preload. This client instead shows ventricular dilation and severe mitral regurgitation on echocardiogram. The hemodynamic collapse and volume overload are inconsistent with HCM pathology.

• Administer dopamine: Dopamine at low to moderate doses supports cardiac output by improving myocardial contractility and maintaining blood pressure. The client’s hypotension and signs of poor perfusion make vasoactive support essential. Dopamine helps preserve end-organ perfusion while definitive surgical intervention is planned.

• Administer morphine: Morphine reduces preload and afterload by promoting venodilation, which decreases pulmonary congestion and myocardial oxygen demand. It also relieves severe chest pain and anxiety, both of which increase sympathetic stimulation and worsen cardiac workload. In cardiogenic shock with pulmonary congestion, morphine can improve breathing comfort. Pain control also supports hemodynamic stability.

• Place client on reverse isolation: Reverse isolation is used to protect immunocompromised clients, not those experiencing cardiogenic shock. There is no evidence of neutropenia or infection risk requiring isolation. This intervention would not address perfusion or oxygenation issues. Priority interventions should focus on hemodynamic support.

• Insert nasogastric tube (NGT): An NGT is not indicated in cardiogenic shock unless there is bowel obstruction or severe gastric distention. The client’s hypoactive bowel sounds reflect hypoperfusion, not a gastrointestinal obstruction. Inserting an NGT would not improve cardiac output or oxygenation.

• Transfer client to a cardiac specialty facility: While advanced care is needed, the client is already receiving specialty-level interventions including invasive monitoring and surgical preparation. Immediate stabilization takes priority over transfer logistics. The focus is maintaining perfusion while preparing for mitral valve replacement.

• Urinary output: Urinary output is a sensitive indicator of renal perfusion and overall cardiac output. The client has had no urine output, signaling severe hypoperfusion. Monitoring output allows the nurse to evaluate response to inotropes and fluid management. Improvement suggests better tissue perfusion and stabilization.

• Respiratory rate: An elevated respiratory rate reflects hypoxia and pulmonary congestion caused by left-sided cardiac failure. Monitoring respirations helps assess oxygenation status and response to interventions such as morphine and oxygen therapy. Decreasing tachypnea indicates improved pulmonary circulation and gas exchange.

• Sulfate sensitivity: There is no indication of medication allergy or hypersensitivity reactions. Monitoring sulfate sensitivity is unrelated to the client’s cardiovascular instability. This parameter does not provide information about cardiac output or perfusion.

• Neck vein distention: Neck vein distention reflects volume overload and elevated central venous pressure but does not adequately assess improvement in shock state. While present, it is less useful for tracking response to therapy than urine output or respiratory status. Shock management focuses on perfusion rather than static volume indicators.

• Angioedema: Angioedema is associated with allergic reactions and airway compromise, which are not evident in this case. There is no facial swelling or airway involvement reported. Monitoring for angioedema would not help assess cardiogenic shock progression.
