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.
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. Bronchophony: Bronchophony is an increase in clarity of spoken sounds when auscultating the lungs, typically indicating lung consolidation or pathology. It is not an adventitious sound associated with airflow through narrowed bronchioles.
B. Wheezes: Wheezes are high-pitched, musical sounds that occur when air passes through narrowed or obstructed airways, such as in cases of severe asthma. They are often heard during expiration and indicate bronchoconstriction or inflammation in the airways. This is the correct answer for the scenario presented.
C. Bronchial sounds: Bronchial sounds are normal breath sounds typically heard over the trachea and major bronchi. They are characterized by a higher pitch and a hollow quality. They are not classified as adventitious sounds and are not indicative of asthma.
D. Whispered pectoriloquy: Whispered pectoriloquy is a clinical finding where whispered sounds are heard more clearly over areas of lung consolidation. Like bronchophony, it does not represent an adventitious sound caused by airflow through narrowed bronchioles and is more indicative of lung pathology.
Correct Answer is ["B","C","E","F"]
Explanation
A. Forlani: No known clinical test named "Forlani" is used to assess the acoustic nerve (cranial nerve VIII). Standard assessments for hearing and vestibular function do not include this test, making this an incorrect option.
B. Rinne: The Rinne test evaluates conductive versus sensorineural hearing loss by comparing air conduction and bone conduction using a tuning fork. Normally, air conduction should be greater than bone conduction, but in conductive hearing loss, bone conduction is either equal to or greater than air conduction. It helps assess cranial nerve VIII function and differentiate between middle and inner ear pathology.
C. Weber: The Weber test is another tuning fork test used to differentiate between conductive and sensorineural hearing loss. The tuning fork is placed on the midline of the forehead, and sound should be heard equally in both ears. If sound lateralizes to one ear, it suggests conductive hearing loss in that ear or sensorineural loss in the opposite ear, aiding in the evaluation of cranial nerve VIII.
D. Kinecki: No known clinical test named "Kinecki" is used to assess the acoustic nerve. The main tests for hearing assessment involve tuning forks, spoken-word tests, and audiometry, none of which include a test by this name, making this option incorrect.
E. Whisper Test: The Whisper Test is a simple screening method to assess hearing by whispering words or numbers behind the patient and having them repeat what was heard. This test evaluates the function of cranial nerve VIII by determining whether the patient can perceive soft sounds at a standard distance, providing a quick but effective measure of hearing acuity.
F. Audiogram (formal hearing test): An audiogram is a comprehensive, formal test that measures hearing ability at different frequencies and intensities. It provides detailed information about sensorineural and conductive hearing loss by assessing how well different pitches and volumes are detected, making it one of the most accurate methods for evaluating cranial nerve VIII function.
