The nurse is teaching a client with cancer about skin care for the portal site receiving external beam radiation. Which client action regarding skin care indicates a need for further teaching?

Choice A reason: This is correct because abdominal obesity, also known as central obesity or visceral fat, is one of the criteria for diagnosing metabolic syndrome and a major risk factor for diabetes mellitus and vascular disease. Abdominal obesity is defined as having a waist circumference of more than 40 inches (102 cm) for men or 35 inches (88 cm) for women. Abdominal obesity can increase insulin resistance, inflammation, and blood pressure, which can lead to impaired glucose metabolism and cardiovascular complications.

Choice B reason: This is correct because blood pressure of 150/96 mm Hg is another criterion for diagnosing metabolic syndrome and a significant risk factor for diabetes mellitus and vascular disease. Blood pressure is defined as the force exerted by blood against the walls of blood vessels. Normal blood pressure is less than 120/80 mm Hg, while high blood pressure (hypertension) is 140/90 mm Hg or higher. High blood pressure can damage the blood vessels and organs, such as the heart, kidneys, eyes, and brain, and increase the risk of heart attack, stroke, kidney failure, and vision loss.

Choice C reason: This is incorrect because elevated high density lipoproteins (HDL), also known as good cholesterol, are not a criterion for diagnosing metabolic syndrome or a risk factor for diabetes mellitus and vascular disease. In fact, HDL are beneficial for cardiovascular health because they help remove excess cholesterol from the blood and prevent plaque buildup in the arteries. Normal HDL levels are 40 mg/dL (1.0 mmol/L) or higher for men and 50 mg/dL (1.3 mmol/L) or higher for women.

Choice D reason: This is correct because increased triglyceride levels are another criterion for diagnosing metabolic syndrome and a risk factor for diabetes mellitus and vascular disease. Triglycerides are a type of fat that circulates in the blood and provides energy to cells. Normal triglyceride levels are less than 150 mg/dL (1.7 mmol/L), while high triglyceride levels are 200 mg/dL (2.3 mmol/L) or higher. High triglyceride levels can increase insulin resistance, inflammation, and blood clotting, which can impair glucose metabolism and increase the risk of heart attack and stroke.

Choice E reason: This is correct because hyperglycemia, also known as high blood sugar, is another criterion for diagnosing metabolic syndrome and a hallmark of diabetes mellitus. Hyperglycemia occurs when the body cannot produce enough insulin or use it properly to regulate the amount of glucose in the blood. Normal blood glucose levels are 70 to 99 mg/dL (3.9 to 5.5 mmol/L) before meals and less than 140 mg/dL (7.8 mmol/L) two hours after meals, while hyperglycemia is 126 mg/dL (7.0 mmol/L) or higher before meals or 200 mg/dL (11.1 mmol/L) or higher two hours after meals. Hyperglycemia can damage the blood vessels and organs, such as the eyes, kidneys, nerves, and feet, and increase the risk of infections, ulcers, amputations, and diabetic ketoacidosis.

Choice F reason: This is incorrect because hypothyroidism, also known as underactive thyroid, is not a criterion for diagnosing metabolic syndrome or a direct risk factor for diabetes mellitus and vascular disease. Hypothyroidism occurs when the thyroid gland does not produce enough thyroid hormones, which regulate the body's metabolism, growth, and development. Hypothyroidism can cause symptoms such as fatigue, weight gain, cold intolerance, dry skin, hair loss, constipation, and depression. However, hypothyroidism does not affect the blood glucose or lipid levels directly, but rather indirectly through its effects on weight and appetite.

Choice A reason: Place the client in a room near the elevator: This does **not** promote client safety, because it exposes the client to more noise and disturbance, which can increase stress and blood pressure. A quiet and calm environment is preferable for stroke clients.

Choice B reason: Complete a swallow study before giving anything by mouth: This **promotes** client safety, because it assesses the client's ability to swallow and prevent aspiration. Stroke clients may have impaired swallowing due to facial weakness or sensory loss.

Choice C reason: Provide a call button kept within reach: This **promotes** client safety, because it allows the client to communicate their needs and request assistance when needed. Stroke clients may have limited mobility or vision, which can increase their risk of falls or injuries.

Choice D reason: Initiate use of the bed alarm: This **promotes** client safety, because it alerts the staff if the client tries to get out of bed without assistance. Stroke clients may have impaired judgment or balance, which can lead to falls or accidents.

Choice E reason: Place client belongings out of reach: This does **not** promote client safety, because it makes the client feel frustrated and helpless. Stroke clients may have difficulty reaching for their belongings due to hemiparesis or hemiplegia, which can affect their self-care and independence. The nurse should place the client's belongings within reach on their unaffected side and encourage them to use them as much as possible.

Choice F reason: Instruct the client to call before getting up: This **promotes** client safety, because it ensures that the client has adequate support and supervision when getting up. Stroke clients may have orthostatic hypotension, which can cause dizziness or fainting when changing positions. The nurse should assist the client to get up slowly and monitor their vital signs.
