A nurse is preparing to administer heparin 15,000 units every 12 hr subcutaneously to a client who weighs 80 kg. Available is 10,000 units/mL. How many mL should the nurse administer with each dose?

(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A: This is incorrect. The client having difficulty reading large print indicates a need for an ophthalmology referral, not an occupational therapy referral. An ophthalmologist can assess and treat vision problems caused by stroke.

Choice B: This is incorrect. The client coughing while drinking from a straw indicates a need for a speech therapy referral, not an occupational therapy referral. A speech therapist can assess and treat swallowing problems caused by stroke.

Choice C: This is incorrect. The client being unable to bear her full weight while walking indicates a need for a physical therapy referral, not an occupational therapy referral. A physical therapist can assess and treat mobility problems caused by stroke.

Choice D: This is correct. The client becoming exhausted while brushing her teeth indicates a need for an occupational therapy referral. An occupational therapist can assess and treat functional problems caused by stroke, such as fatigue, self-care, cognition, and leisure activities.

Choice A reason: Taking ibuprofen or other nonsteroidal anti-inflammatory drugs (NSAIDs) can cause a false-positive result on a fecal occult blood screening test, as they can irritate the gastrointestinal mucosa and cause bleeding.

Choice B reason: Having a hemorrhoidectomy 1 year ago is unlikely to cause a false-positive result on a fecal occult blood screening test, as hemorrhoids are usually a source of bright red blood that can be seen with naked eye, not occult blood that requires chemical detection.

Choice C reason: Having a history of breast cancer is not related to a false-positive result on a fecal occult blood screening test, as breast cancer does not affect the gastrointestinal tract or cause bleeding in stool.

Choice D reason: Consuming citrus juice 3 days before the test is not likely to cause a false-positive result on a fecal occult blood screening test, as citrus juice does not contain any substances that can interfere with the chemical reaction of the test. However, consuming red meat, raw vegetables, vitamin C supplements, or iron supplements within 3 days before the test can cause false-negative results, as they can mask or degrade occult blood in stool.
