A nurse assesses four patients. Which patient has greatest risk for hypomagnesemia?

A. "It might help if I tried sleeping only on my back."
Sleeping on the back can actually worsen obstructive sleep apnea because gravity can cause the tongue and soft tissues to obstruct the airway more easily. The recommended position to reduce apneic episodes is to sleep on the side.

B. "I’ll sleep better if I take a sleeping pill at night."
Taking a sleeping pill can relax the muscles of the throat, which might worsen sleep apnea by increasing the likelihood of airway obstruction during sleep.

C. "If I could lose about 50 pounds, I might stop having so many apneic episodes."
Weight loss is a key factor in reducing the frequency and severity of obstructive sleep apnea. Excess weight, particularly around the neck, can increase the risk of airway obstruction during sleep.

D. "I’ll get a humidifier to run at my bedside at night."
While a humidifier can make the air more comfortable to breathe, it does not directly reduce the number of apneic episodes. It might help with symptoms like dry mouth or nasal congestion but is not a primary treatment for obstructive sleep apnea.

A) Painful urination: Painful urination, also known as dysuria, is not a typical symptom of BPH. Dysuria is more commonly associated with conditions such as urinary tract infections (UTIs) or urethritis rather than BPH.

B) Urge incontinence: While BPH can cause lower urinary tract symptoms such as urgency and frequency, urge incontinence (involuntary loss of urine associated with a sudden urge to urinate) is not typically a primary symptom of BPH. Urge incontinence is more commonly associated with overactive bladder (OAB) syndrome.

C) Critically elevated prostate-specific antigen (PSA) level: While BPH can cause an elevation in PSA levels, a critically elevated PSA level alone is not a definitive diagnostic finding for BPH. PSA levels can be elevated in various conditions affecting the prostate gland, including BPH, prostate cancer, and prostatitis. Therefore, PSA levels must be interpreted in conjunction with other clinical findings and diagnostic tests to accurately assess prostate health and diagnose specific prostate conditions.

D) Difficulty starting the flow of urine: Benign prostatic hyperplasia (BPH) is characterized by the enlargement of the prostate gland, which can obstruct the flow of urine through the urethra. This obstruction leads to symptoms such as difficulty starting the flow of urine, weak urinary stream, urinary hesitancy, and incomplete bladder emptying. These symptoms occur due to the mechanical obstruction of the urethra by the enlarged prostate gland. Difficulty starting the flow of urine is a hallmark symptom of BPH and is often one of the earliest manifestations experienced by affected individuals.
