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 ["B","C"]

Explanation

B. stroke volume is the amount of blood ejected from the left ventricle with each contraction (systole) of the heart. Changes in stroke volume directly affect cardiac output. An increase in stroke volume leads to an increase in cardiac output, while a decrease in stroke volume results in a decrease in cardiac output. Factors that can affect stroke volume include preload, afterload, and contractility of the heart.

C. Heart rate refers to the number of heartbeats per minute. Heart rate directly affects cardiac output by determining how frequently the heart contracts and pumps blood. An increase in heart rate (tachycardia) leads to an increase in cardiac output, while a decrease in heart rate (bradycardia) results in a decrease in cardiac output. Factors such as sympathetic and parasympathetic nervous system activity, hormones, and medications can influence heart rate.

A. Respiratory rate does not directly affect stroke volume or heart rate but changes in respiratory rate can indirectly impact cardiac output through their effects on venous return and preload.

D. Blood pressure represents the force exerted by the blood against the walls of the arteries. While blood pressure does not directly affect cardiac output, it is influenced by cardiac output and systemic vascular resistance (SVR).

A. Bradycardia. B. Muffled heart sounds C. Flattened neck veins. D. Sudden lethargy.

Correct Answer is B

Explanation

B. Muffled heart sounds, often described as distant or indistinct, are classic findings in cardiac tamponade. The accumulation of fluid in the pericardial sac dampens the transmission of sound from the heart to the chest wall, resulting in muffled heart sounds on auscultation. This finding is known as Beck's triad, which also includes hypotension and jugular venous distention.

A. Bradycardia is not a typical finding in cardiac tamponade. In fact, tachycardia is more commonly observed due to the compensatory response to decreased cardiac output and decreased stroke volume. The sympathetic nervous system is activated, leading to an increase in heart rate as a compensatory mechanism to maintain cardiac output.

C. Flattened neck veins are not consistent with cardiac tamponade. In cardiac tamponade, jugular venous distention (JVD) is typically observed due to increased venous pressure resulting from impaired right ventricular filling. The presence of JVD is an important clinical finding in cardiac tamponade and can help differentiate it from other causes of shock.

D. Sudden lethargy can occur in various medical emergencies, including cardiac tamponade, but it is not a specific or diagnostic finding for this condition. In cardiac tamponade, symptoms may include dyspnea, chest pain, hypotension, and signs of decreased cardiac output such as cool extremities and altered mental status. However, sudden lethargy alone may not be specific enough to confirm cardiac tamponade.
