One day after giving birth to a 4050-g (8-lb 15-oz) male newborn, a 22-year-old woman experiences involuntary loss of urine. The urine loss occurs intermittently in the absence of an urge to urinate. It is not exacerbated by sneezing or coughing. Pregnancy was uncomplicated except for two urinary tract infections that were treated with nitrofurantoin. Delivery was complicated by prolonged labor and severe labor pains; the patient received epidural analgesia. Her temperature is 36.2°C (97.2°F), pulse is 70/min, and blood pressure is 118/70 mm Hg. The abdomen is distended and tender to deep palpation. Pelvic examination shows a uterus that extends to the umbilicus; there is copious thick, whitish-red vaginal discharge. Neurologic examination shows no abnormalities. Which of the following is the most likely cause of this patient's urinary incontinence?
ACurrent urinary tract infection
BDamage to nerve fibers
CRecurrent urinary tract infections
DProlonged labor
EBladder atony
A 62-year-old man presents to the office because of painless rectal bleeding for the past 3 months. He describes intermittent streaks of bright red blood on the toilet paper after wiping and blood on but not mixed within the stool. Occasionally, he has noted a small volume of blood within the toilet bowl, and he associates this with straining. For the past 2 weeks, he has noticed an 'uncomfortable lump' in his anus when defecating, which goes away by itself immediately afterwards. He says he has no abdominal pain, weight loss, or fevers. He is a well-appearing man that is slightly obese. Digital rectal examination shows bright red blood on the examination glove following the procedure. Anoscopy shows enlarged blood vessels above the pectinate line. Which of the following is the most likely cause?
AGrade 2 internal hemorrhoids
BGrade 3 internal hemorrhoids
CThrombosed external hemorrhoids
DGrade 1 internal hemorrhoids
