When assessing a patient's lungs, what should the nurse recall about the left lung?

Is shorter than the right lung because of the underlying stomach.

Primarily consists of an upper lobe on the posterior chest.

Is divided by the horizontal fissure.

Consists of two lobes.

Answer and Explanation

The Correct Answer is D

A. Is shorter than the right lung because of the underlying stomach: The right lung is actually shorter than the left lung due to the position of the liver beneath it, which pushes the right diaphragm higher. The left lung is longer but narrower due to the space occupied by the heart.

B. Primarily consists of an upper lobe on the posterior chest: The left lung has both upper and lower lobes visible on the posterior chest. The lower lobe is larger and occupies most of the posterior lung field, while the upper lobe is primarily seen anteriorly and laterally.

C. Is divided by the horizontal fissure: The horizontal fissure is found in the right lung, separating the upper and middle lobes. The left lung has only one fissure, the oblique fissure, which separates its two lobes.

D. Consists of two lobes: The left lung is divided into an upper and lower lobe by the oblique fissure. Unlike the right lung, which has three lobes, the left lung has only two due to the space occupied by the heart, forming the cardiac notch.

Correct Answer is B

Explanation

A. Loss of the outer hair on the eyebrows attributable to a decrease in hair follicles: It is normal for older adults to experience changes in hair growth, including loss of eyebrow hair due to a decrease in hair follicles. This finding is considered a typical age-related change and not abnormal.

B. Unequal pupillary constriction in response to light: This finding is considered abnormal and may indicate a potential neurological issue or damage to the optic or oculomotor nerves. Normal pupillary response should be equal and reactive to light, so any discrepancy in pupillary constriction warrants further evaluation.

C. Decrease in tear production: A decrease in tear production is common in older adults due to age-related changes in lacrimal gland function. This condition, known as dry eye syndrome, is not considered abnormal for this age group.

D. Presence of arcus senilis observed around the cornea: Arcus senilis is characterized by a gray or white ring around the cornea due to lipid deposits and is commonly seen in older adults. While it may indicate elevated cholesterol levels in younger individuals, its presence in elderly patients is usually not abnormal.

A. May show evidence of some clouding of his level of consciousness. B. Will be oriented to place and person, but the patient may not be certain of the date. C. Disruptive behavior D. Will state, "I am so relieved to be out of intensive care."

Correct Answer is B

Explanation

A. May show evidence of some clouding of his level of consciousness: While patients who have been in intensive care for an extended period may experience some clouding of consciousness or altered mental status, it is not a universal finding. This option implies a more significant alteration in consciousness than typically expected in a patient transitioning to a medical-surgical unit.

B. Will be oriented to place and person, but the patient may not be certain of the date: This is a common expectation for patients who have been in an intensive care setting for a prolonged period. They may maintain orientation to person and place due to their familiarity with the environment and staff, but they might have difficulty recalling the date due to the stress of hospitalization and changes in routine.

C. Disruptive behavior: While some patients may exhibit changes in behavior after a long stay in intensive care, it is not a standard expectation. Many patients may be more subdued and fatigued rather than disruptive.

D. Will state, "I am so relieved to be out of intensive care": While this response might occur, it is not guaranteed. Patients may have mixed emotions about their transition from intensive care, including anxiety or confusion. Therefore, this statement is not a definitive expectation during the mental status examination.
