The nurse is performing an assessment of the clients lungs. The nurse recognizes that the left lung:
Consists of two lobes.
Primarily consists of an upper lobe on the posterior chest.
Is shorter than the right lung because of the underlying stomach.
is divided by the horizontal fissure.
The Correct Answer is A
A. Consists of two lobes.
This statement is correct. The left lung consists of two lobes: the upper lobe and the lower lobe. The right lung, not the left lung, has three lobes: upper, middle, and lower lobes.
B. Primarily consists of an upper lobe on the posterior chest.
This statement is not accurate. The upper lobe of the left lung is present in the anterior and posterior parts of the chest. It is not limited to the posterior chest.
C. Is shorter than the right lung because of the underlying stomach.
This statement is not correct. The left lung is not shorter due to the underlying stomach. The left lung is slightly smaller than the right lung to accommodate the space for the heart, but this size difference is not due to the stomach.
D. Is divided by the horizontal fissure.
This statement is not accurate. The left lung is not divided by the horizontal fissure. The horizontal fissure is a feature of the right lung, not the left lung. The left lung is divided by the oblique fissure into the upper and lower lobes

Correct Answer is A
Explanation
A. Wheezes:
Wheezes are continuous, high-pitched, whistling lung sounds that are heard especially during expiration and sometimes during inspiration. They are caused by the rapid movement of air through narrowed or constricted airways, which is common in conditions like asthma. Wheezing is a characteristic adventitious sound associated with asthma and other obstructive respiratory disorders.
B. Whispered Pectoriloquy:
Whispered Pectoriloquy is an increased loudness of whispering noted during auscultation with a stethoscope on the lung fields. This phenomenon occurs when sound is transmitted clearly through consolidated or compressed lung tissue, making whispered sounds more distinct. It is a sign of lung consolidation, often seen in conditions like pneumonia.
C. Bronchial Sounds:
Bronchial sounds are harsh, high-pitched sounds heard over the trachea and the large bronchi. These sounds are normally heard during expiration. If they are heard over peripheral lung areas, it can indicate consolidation or compression of lung tissue, possibly due to pneumonia or tumor.
D. Bronchophony:
Bronchophony is a phenomenon in which spoken sounds are heard more clearly and distinctly through the stethoscope on auscultation of the lungs. Normally, sounds are muffled during auscultation. Increased clarity of spoken sounds can indicate lung consolidation, similar to whispered pectoriloquy, and is often associated with conditions like pneumonia.
Correct Answer is C
Explanation
In this sequence:
Vena cava brings deoxygenated blood from the body into the right atrium.
Blood flows from the right atrium to the right ventricle through the tricuspid valve.
The right ventricle pumps blood into the pulmonary artery to the lungs.
In the lungs, blood is oxygenated and returns to the heart via the pulmonary veins into the left atrium.
From the left atrium, blood moves to the left ventricle through the bicuspid (mitral) valve.
The left ventricle then pumps oxygenated blood into the body through the aorta.
This sequence represents the systemic and pulmonary circulation of the heart.
