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.

Answer and Explanation

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 D

Explanation

A. Indicates the beginning of diastole: This statement is not accurate. S2, the second heart sound, indicates the end of systole and the beginning of diastole. It is specifically associated with the closure of the aortic and pulmonary valves.

B. Coincides with the carotid artery pulse: This statement is not accurate. S2 is associated with the closure of the aortic and pulmonary valves in the heart, not with the carotid artery pulse.

C. Is louder than an S1: This statement is not accurate. S1, the first heart sound, is usually louder than S2. S1 is associated with the closure of the mitral and tricuspid valves and marks the beginning of systole.

D. Is caused by the closure of the semilunar valves: This statement is accurate. S2 is caused by the closure of the aortic and pulmonary valves, which are the semilunar valves in the heart. It marks the end of systole and the beginning of diastole.

A. The eyes converge to focus on the light. B. The eye focuses the image in the center of the pupil. C. Dilation of both pupils occurs in response to bright light. D. Constriction of both pupils occurs in response to bright light.

Correct Answer is D

Explanation

A. The eyes converge to focus on the light.

This statement refers to the convergence reflex, where both eyes move medially (towards each other) to maintain single binocular vision when focusing on a near object. It is not related to the pupillary light reflex, which involves changes in pupil size in response to light.

B. The eye focuses the image in the center of the pupil.

This choice does not accurately describe the pupillary light reflex. The pupillary light reflex involves constriction of the pupil in response to light, not focusing an image in the center of the pupil.

C. Dilation of both pupils occurs in response to bright light.

This statement is incorrect. In response to bright light, the pupils should constrict, not dilate. Dilation of pupils in bright light could indicate an abnormal response, such as in cases of certain neurological conditions or drug use.

D. Constriction of both pupils occurs in response to bright light.

This choice is correct. In the pupillary light reflex, both pupils constrict when exposed to bright light. This response is a protective mechanism to prevent excessive light from entering the eyes, ensuring optimal visual acuity.
