A 69-year-old male presents to the primary care clinic with progressive lower urinary tract symptoms over the past year, including urinary hesitancy, weak stream, nocturia (3–4 times nightly), and a sensation of incomplete bladder emptying. He denies dysuria or hematuria. Digital rectal exam reveals a symmetrically enlarged, smooth prostate. PSA is mildly elevated but stable compared with prior results. Transrectal ultrasound estimates prostate volume at 45 g. You conclude his diagnosis is benign prostatic hypertrophy with moderate to severe symptoms and an enlarged prostate. His medical history includes hypertension and hyperlipidemia, both well controlled. Current medications include amlodipine and atorvastatin. He reports no history of orthostatic hypotension. Question Which pharmacologic management plan is most appropriate at this time?

Suppose you fill up your tires with air in the summer when the ambient temperature is 80°F. You fill them up to 35 psi or 241,000 Pa gauge pressure. If the volume of the tire stays the same, and no air enters or leaves the tire, what will the gauge pressure be in winter when the ambient temperature is 15°F?
