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

Abnormal growth results in loss of bladder muscle tone.

Inflammation causes spasms of the gland.

The enlarged gland compresses the urethra.

Nerve compression decreases the sensation that the bladder is full

Answer and Explanation

The Correct Answer is C

Benign prostatic hyperplasia (BPH) is a condition characterized by non-cancerous growth of the prostate gland, leading to its enlargement. This enlargement can contribute to urinary retention by obstructing the flow of urine through the urethra. Here's the breakdown of the explanation:

A) Abnormal growth results in loss of bladder muscle tone:

While BPH can lead to urinary symptoms such as urinary frequency, urgency, and nocturia, it does not directly cause loss of bladder muscle tone. Instead, the enlarged prostate gland obstructs the bladder outlet, making it difficult for urine to pass through the urethra.

B) Inflammation causes spasms of the gland:

Inflammation of the prostate gland, known as prostatitis, can cause symptoms such as pelvic pain, dysuria, and urinary frequency, but it is not typically associated with BPH. BPH is characterized by benign growth of the prostate tissue rather than inflammation and spasms.

C) The enlarged gland compresses the urethra:

Correct. The primary mechanism by which BPH causes urinary retention is by compressing the urethra, which obstructs the flow of urine from the bladder. As the prostate gland enlarges, it can constrict the urethra, leading to symptoms such as hesitancy, weak urinary stream, incomplete emptying, and urinary retention.

D) Nerve compression decreases the sensation that the bladder is full:

While compression of nerves in the pelvic region can contribute to urinary symptoms, such as decreased sensation of bladder fullness, it is not the primary mechanism by which BPH causes urinary retention. The compression of the urethra by the enlarged prostate gland is the main factor leading to urinary obstruction and retention.

Correct Answer is C

Explanation

Smoking is a well-established risk factor for lung cancer, and the pathophysiological process underlying this association involves the exposure of the lungs to carcinogenic agents present in tobacco smoke. Here's why option C is the correct choice:

A) Vasoconstrictive properties of nicotine reduce oxygenation and stimulate metabolism:

While nicotine is a primary addictive component of tobacco smoke and can lead to vasoconstriction, reduced oxygenation, and increased metabolism, these effects primarily contribute to cardiovascular diseases associated with smoking, such as coronary artery disease and stroke, rather than the development of lung cancer.

B) Drug addiction changes the neurochemical messages in the brain causing cravings:

This statement addresses the addictive nature of nicotine and its impact on neurochemistry, leading to cravings and dependence. While addiction is a significant aspect of tobacco use, it does not directly explain the pathophysiological process by which smoking causes lung cancer.

C) Carcinogenic agents in tobacco alter cellular cytology, morphology, and function of the lung:

Correct. Tobacco smoke contains numerous carcinogenic compounds, such as polycyclic aromatic hydrocarbons (PAHs), nitrosamines, and benzene, which can directly damage the DNA of lung cells. This DNA damage can lead to mutations and alterations in cellular cytology, morphology, and function, ultimately contributing to the development of lung cancer.

D) Risk for comorbidities increase incidence of chronic diseases and decrease longevity:

While smoking is associated with an increased risk of various comorbidities and chronic diseases, such as cardiovascular diseases, respiratory diseases, and certain cancers, this option does not specifically address the pathophysiological process of lung cancer development.

A. Herpes simplex virus. B. Vulvovaginitis. C. Human papillomavirus (HPV). D. Chronic yeast infections.

Correct Answer is C

Explanation

A. Herpes simplex virus:

While herpes simplex virus (HSV) infection is a sexually transmitted infection that can cause genital ulcers and lesions, it is not directly associated with an increased risk of cervical cancer. However, individuals with genital herpes may have an increased risk of acquiring human papillomavirus (HPV), which is a significant risk factor for cervical cancer.

B. Vulvovaginitis:

Vulvovaginitis refers to inflammation or infection of the vulva and vagina and can be caused by various factors, including bacterial, fungal, or viral infections. While chronic inflammation or infection may contribute to cellular changes in the cervix, it is not a direct risk factor for cervical cancer.

C. Human papillomavirus (HPV):

Human papillomavirus (HPV) infection is the most significant risk factor for developing cervical cancer. Certain high-risk strains of HPV, particularly HPV types 16 and 18, are strongly associated with the development of cervical dysplasia and cervical cancer. Persistent infection with high-risk HPV strains can lead to cellular changes in the cervix, eventually progressing to cervical cancer.

D. Chronic yeast infections:

Chronic yeast infections, also known as recurrent vulvovaginal candidiasis, are caused by the overgrowth of Candida species in the vaginal area. While chronic yeast infections can cause discomfort and recurrent symptoms, they are not directly linked to an increased risk of cervical cancer. However, chronic irritation or inflammation in the genital area may increase the susceptibility to other infections, including HPV.
