A nurse is preparing to administer amoxicillin 30 mg/kg/day in 2 equally divided doses every 12 hr to a toddler who weighs 33 lb. Available is amoxicillin 200 mg/5 mL suspension.

How many mL should the nurse administer per dose?

Choice A rationale

A colonoscopy is the standard investigation for colorectal cancer. It allows for the visualization of the entire colon and rectum, and can also allow for the removal of polyps and the taking of biopsies if needed.

Choice B rationale

Endoscopic retrograde cholangiopancreatography (ERCP) is a procedure used to diagnose diseases of the gallbladder, biliary system, pancreas, and liver, not rectal cancer.

Choice C rationale

An upper GI series, which involves X-rays of the esophagus, stomach, and small intestine, would not be used for screening for rectal cancer.

Choice D rationale

An upper GI endoscopy, which involves the use of a flexible endoscope to visualize the esophagus, stomach, and duodenum, would not be used for screening for rectal cancer.

Choice A rationale

Glaucoma is a condition that damages the eye’s optic nerve and can result in vision loss and blindness. However, it doesn’t cause a cloudy, opaque area over the lens of the eye.

Choice B rationale

Diabetic retinopathy is a diabetes complication that affects eyes. It’s caused by damage to the blood vessels of the light-sensitive tissue at the back of the eye (retina). But it doesn’t cause a cloudy, opaque area over the lens of the eye.

Choice C rationale

Macular degeneration is a medical condition which may result in blurred or no vision in the center of the visual field. But it doesn’t cause a cloudy, opaque area over the lens of the eye.

Choice D rationale

A cataract is a clouding of the lens in the eye that affects vision. Cataracts are very common in older people. Symptoms of cataracts include cloudy or blurry vision.
