Correct Answer is D

Explanation

A. Thigh muscles: While thigh muscles assist in venous return, they are not as critical as the calf muscles in moving blood from the feet.

B. Arterial pulsations: Arterial pulsations help in the forward movement of blood in the arteries but do not directly assist with venous return from the feet.

C. Venous flow: Venous flow is the general term for blood movement in veins, but it does not specify the mechanism responsible for moving blood from the feet.

D. Calf muscles: The calf muscles, through their contraction (often referred to as the "muscle pump"), are crucial in helping to push blood upwards from the feet towards the inferior vena cava. This mechanism is essential for effective venous return.

A. Bronchitis B. Heart failure C. Pneumonia D. Tuberculosis

Correct Answer is B

Explanation

A. Bronchitis primarily causes coughing and mucus production, and does not specifically relate to trouble breathing while lying down.

B. Heart failure often leads to orthopnea (difficulty breathing while lying flat) and paroxysmal nocturnal dyspnea (waking up at night with difficulty breathing). These symptoms align with the client's reported issues.

C. Pneumonia usually presents with acute symptoms such as cough, fever, and chest pain, rather than the specific nocturnal breathing difficulty described.

D. Tuberculosis typically involves symptoms like chronic cough, night sweats, and weight loss, rather than difficulty breathing while lying down.
