Which explanation should the nurse give to a male client on why benign prostatic hyperplasia (BPH) often causes urinary retention

A) Bronchioles:

Bronchioles are small airways in the lungs that lack cartilage and are primarily responsible for conducting air to the alveoli. While changes in bronchioles, such as bronchoconstriction or bronchiolitis, can contribute to airflow limitation in conditions like asthma or chronic bronchitis, they are not primarily associated with the pathophysiological processes of emphysema.

B) Trachea:

The trachea, or windpipe, is the large airway that connects the larynx to the bronchi. It serves as a conduit for air movement into and out of the lungs but is not directly involved in gas exchange. Changes in the trachea are not typically associated with the pathophysiological processes of emphysema.

C) Bronchi:

Bronchi are larger airways in the lungs that branch off from the trachea and further divide into bronchioles. While chronic bronchitis, a common comorbidity of emphysema in chronic obstructive pulmonary disease (COPD), primarily affects the bronchi, it is not the primary structure associated with the pathophysiological processes of emphysema.

D) Alveoli:

Correct. Emphysema is a type of COPD characterized by the destruction of alveolar walls, leading to enlarged airspaces and loss of lung elasticity. This structural damage results in decreased surface area for gas exchange and impaired diffusion of oxygen and carbon dioxide across the alveolar-capillary membrane. Alveolar destruction in emphysema leads to poor gas exchange and contributes to the characteristic symptoms of dyspnea, hypoxemia, and hypercapnia in affected individuals. Therefore, the alveoli are directly associated with the pathophysiological processes of emphysema

Gout is a form of inflammatory arthritis characterized by sudden, severe attacks of pain, redness, and swelling in the joints, commonly affecting the big toe joint (first metatarsophalangeal joint). The primary pathophysiological process underlying gout involves the deposition of monosodium urate crystals in the joints and surrounding tissues. Here's an explanation of why option A is the correct answer:

A) Deposition of crystals in the synovial space of the joints produces inflammation and irritation:

Correct. Elevated levels of uric acid in the blood can lead to the formation of monosodium urate crystals, which then accumulate in the synovial fluid of joints, particularly in the big toe joint in many cases. These crystals trigger an inflammatory response, activating immune cells and causing swelling, redness, warmth, and severe pain in the affected joint. The inflammation and irritation result from the body's response to the presence of these crystals.

B) Chondrocyte injury destroys joint cartilage, producing osteophytes and joint inflammation:

This option describes a process more characteristic of osteoarthritis, where degeneration of joint cartilage leads to inflammation and the formation of osteophytes (bone spurs). Gout does not directly involve chondrocyte injury.

C) An immune complex and autoantibody deposition in connective tissue results in inflammation:

This process describes the pathophysiology of autoimmune diseases such as rheumatoid arthritis, where immune complexes and autoantibodies contribute to inflammation and tissue damage. In gout, the inflammation is primarily triggered by the deposition of urate crystals rather than immune complex deposition.

D) An autoimmune inflammation involving IgG response to an antigen causes joint destruction:

This option describes the autoimmune process seen in diseases like rheumatoid arthritis, where antibodies target specific antigens, leading to joint destruction. Gout is not an autoimmune disease, and joint destruction in gout is primarily due to inflammation caused by urate crystal deposition rather than autoimmune mechanisms.
