A nurse is reinforcing teaching about foot care for a client who has diabetes. Which of the following client statements indicates an understanding of the teaching?

I can apply lotion between my toes after showering.

I can wear open-toe shoes.

I should wear cotton socks.

I should round the corners of my toenails when trimming them.

Answer and Explanation

The Correct Answer is C

Choice A: This is incorrect because applying lotion between the toes can create a moist environment that promotes fungal growth and infection. The client should apply lotion to the feet but avoid the areas between the toes.

Choice B: This is incorrect because wearing open-toe shoes can expose the feet to injury and infection. The client should wear well-fitting, closed-toe shoes that protect the feet and prevent pressure ulcers.

Choice C: This is correct because wearing cotton socks can help keep the feet dry and prevent fungal infections. Cotton socks also provide cushioning and reduce friction.

Choice D: This is incorrect because rounding the corners of the toenails can cause ingrown nails, which can lead to infection and ulceration. The client should trim the toenails straight across and file any sharp edges.

Correct Answer is B

Explanation

Choice A reason: Chest x-ray showing cardiomegaly is not a new finding for the client who has heart failure, as it indicates enlargement of the heart due to increased workload and pressure on the cardiac chambers.

Choice B reason: PaCO2 55 mmHg is an abnormal finding for the client who has heart failure, as it indicates respiratory acidosis, which is a condition where the lungs cannot eliminate enough carbon dioxide and the blood becomes too acidic. This can be caused by pulmonary edema, which is a complication of heart failure that impairs gas exchange and ventilation.

Choice C reason: Potassium level 4.5 mEq/L is a normal finding for the client who has heart failure, as it indicates adequate electrolyte balance and renal function.

Choice D reason: Urinary output of 1,000 mL in 12 hr is a normal finding for the client who has heart failure, as it indicates adequate fluid status and cardiac output.

A. The client takes ibuprofen for headaches. B. The client had a hemorrhoidectomy 1 year ago. C. The client has a history of breast cancer. D. The client consumed citrus juice 3 days before the test.

Correct Answer is A

Explanation

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.
