Which of the following is a common cause of cardiogenic shock?

Anaphylaxis

Hypovolemia

Pulmonary embolism

Myocardial infarction

Answer and Explanation

The Correct Answer is D

D. Myocardial infarction (heart attack) is a common cause of cardiogenic shock. In myocardial infarction, part of the heart muscle becomes ischemic or necrotic due to occlusion of a coronary artery. This leads to impaired cardiac function and reduced cardiac output, resulting in cardiogenic shock. Prompt recognition and treatment of myocardial infarction are crucial to prevent or manage cardiogenic shock.
A. Anaphylaxis is a severe allergic reaction that can lead to systemic vasodilation and distributive shock, but it is not a common cause of cardiogenic shock. In anaphylaxis, the primary mechanism of shock is typically related to widespread vasodilation and increased vascular permeability rather than impaired cardiac function.
B. Hypovolemic shock occurs due to a decrease in intravascular volume, leading to inadequate tissue perfusion. It is not a common cause of cardiogenic shock, as the underlying mechanism is different. In hypovolemic shock, the primary issue is the loss of circulating blood volume, whereas cardiogenic shock involves impaired cardiac function.
C. Pulmonary embolism can lead to acute right heart strain or failure, which may result in hemodynamic instability and shock. However, pulmonary embolism typically causes obstructive shock rather than cardiogenic shock. Obstructive shock occurs when blood flow is obstructed, such as by a pulmonary embolism, leading to reduced cardiac output.

Correct Answer is D

Explanation

D. Asystole represents the absence of electrical activity in the heart and is not amenable to defibrillation. Therefore, the RRT would continue cardiopulmonary resuscitation (CPR) with chest compressions and may administer medications or other interventions as indicated. This statement provides accurate information to the family about the patient's condition and the actions being taken by the RRT.

A. Defibrillation is not indicated for asystole. Asystole represents a flatline on the cardiac monitor, indicating the absence of electrical activity in the heart. Defibrillation is only effective for certain types of cardiac rhythms, such as ventricular fibrillation or pulseless ventricular tachycardia. Therefore, the RRT would not use defibrillation for a patient in asystole.

B. It does not provide the family with information about the patient's condition or the actions being taken by the RRT. Moreover, excluding the family from the patient's care may cause additional distress and prevent them from being present to support their loved one during a critical situation.

C. Cardiopulmonary resuscitation (CPR) is performed to maintain blood flow and oxygenation to vital organs during cardiac arrest. However, it does not restore normal blood flow or circulation. The goal of CPR is to provide temporary support until advanced interventions can be initiated or until return of spontaneous circulation (ROSC) is achieved.

A. Position the head of the client's bed in the flat position. B. Provide humidity by maintaining moisture within the ventilator tubing. C. Turn the client every 4 hr. D. Brush the client's teeth with a suction toothbrush every 12 hr.

Correct Answer is D

Explanation

D. Oral hygiene is crucial in reducing the risk of VAP as it helps to reduce the bacterial load in the oral cavity, which can be aspirated into the lower respiratory tract. Using a suction toothbrush to mechanically remove dental plaque and bacteria from the teeth and oral mucosa can help to prevent VAP.

A. Elevating the head of the bed to between 30 and 45 degrees (semi-recumbent position) is recommended to prevent aspiration of oral or gastric contents, which can contribute to the development of VAP. This position helps to promote drainage of secretions and reduces the risk of reflux.

B. While maintaining appropriate humidity levels in the ventilator tubing helps to prevent drying of the respiratory mucosa and promote secretion clearance, it does not directly reduce the risk of VAP. Other interventions are more directly related to VAP prevention.

C. Regular turning and repositioning of the client help to prevent pooling of secretions, improve ventilation-perfusion matching, and reduce the risk of pressure ulcers. Turning the client every 2 hours is often recommended to optimize lung expansion and secretion clearance, thereby reducing the risk of VAP.
