Complete the diagram by dragging from the choices below to specify what condition the client is most likely experiencing, 2 actions the nurse should take to address that condition, and 2 parameters the nurse should monitor to assess the client's progress.

Answer and Explanation

The Correct Answer is []

AF is characterized by irregular, rapid heartbeat (100 to 175 beats per minute (bpm) and the absence of distinct P waves.

Management of unstable atrial fibrillation include immediate pharmacological or electrical cardioversion and anticoagulation.

Atrial fibrillation leads to ineffective pumping and stasis of blood in the heart which increases the risk of stroke.

On initiating anticoagulation, PTT/INR is important to ensure that the drug is administered at doses that achieve the optimal therapeutic effect.

Correct Answer is D

Explanation

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.

A. "PEEP prevents the lung air sacs from collapsing during exhalation." B. "PEEP allows the breathing machine to deliver 100% 02 to the lungs." C. "PEEP will push more air into the lungs during inhalation." D. "PEEP will prevent lung damage while the patient is on the ventilator."

Correct Answer is A

Explanation

A. Positive end-expiratory pressure (PEEP) is applied during mechanical ventilation to prevent alveolar collapse at the end of expiration. It helps maintain the patency of the alveoli, improving oxygenation and preventing atelectasis.
B. While PEEP can improve oxygenation by recruiting collapsed alveoli and increasing functional residual capacity, it does not directly affect the concentration of oxygen delivered by the ventilator. Oxygen concentration is adjusted separately from PEEP settings.
C. PEEP is applied at the end of expiration to maintain positive pressure in the airways and alveoli, preventing them from collapsing. It does not directly affect the delivery of air during inhalation.
D. PEEP can help prevent lung damage by maintaining alveolar recruitment and reducing the risk of atelectasis and barotrauma. However, it is not the sole factor in preventing lung damage, and other ventilator settings and strategies also play a role in protecting the lungs.
