The nurse is discussing the blood flow pattern of the heart. The nurse should recognize which of the following as the accurate blood flow pattern of the heart?

A. Clear and equal breath sounds bilaterally

Explanation: Clear and equal breath sounds bilaterally indicate normal lung sounds, suggesting proper air exchange in both lungs. This is a normal finding and does not require immediate reporting.

B. Oxygen saturation of 98% on room air

Explanation: An oxygen saturation level of 98% on room air indicates adequate oxygenation of the blood. This is a normal and healthy oxygen saturation level and does not require immediate reporting.

C. Cough producing clear, thin sputum

Explanation: A cough producing clear, thin sputum is indicative of a non-infected or non-inflammatory condition in the respiratory system. Clear and thin sputum is often normal, especially in the absence of other symptoms. It does not require immediate reporting unless the client has other concerning symptoms.

D. Visible use of accessory muscles during inhalation

Explanation: Visible use of accessory muscles, such as neck or intercostal muscles, during inhalation suggests that the client is working hard to breathe. This could indicate respiratory distress, potentially due to conditions like asthma, COPD (Chronic Obstructive Pulmonary Disease), or other severe lung problems. It's a concerning sign and should be reported to the healthcare practitioner promptly for further evaluation and intervention.

A. The atria contract toward the end of diastole and push the remaining blood into the ventricles.

This choice is correct. During atrial systole (atrial contraction), the atria contract, pushing the remaining blood into the ventricles. This additional filling of the ventricles optimizes cardiac output.

B. The atria contract during systole and attempt to push against closed valves.

This statement is incorrect. The atria do not contract during systole; they contract during diastole (atrial systole) to fill the ventricles.

C. Atrial kick is the pressure exerted against the atria as the ventricles contract during systole.

This statement is incorrect. Atrial kick refers to the atrial contraction, not the pressure exerted against the atria.

D. Contraction of the atria at the beginning of diastole can be felt as a palpitation.

This statement is not entirely accurate. A palpitation is a sensation of rapid or strong heartbeat, which might be felt during various cardiac events, not specifically during atrial contraction at the beginning of diastole.
