A nurse is providing teaching about blood pressure measurement to a client who has hypertension. Which of the following instructions should the nurse include?
Use an electronic device.
Inflate the cuff to 140/90 mmHg.
Place the cuff on the upper arm.
Measure blood pressure after exercise.
The Correct Answer is C
Choice A reason: Using an electronic device is not a reliable method for measuring blood pressure because it may give inaccurate readings due to movement, noise, or battery issues. An electronic device should be calibrated regularly and compared with a manual device.
Choice B reason: Inflating the cuff to 140/90 mmHg is not a correct procedure for measuring blood pressure because it may cause discomfort and false readings. The cuff should be inflated to about 20 to 30 mmHg above the expected systolic pressure or until the pulse disappears.
Choice C reason: Placing the cuff on the upper arm is a correct procedure for measuring blood pressure because it ensures that the cuff is at the same level as the heart and that the brachial artery is compressed. The cuff should be snug and fit around 80% of the arm circumference.
Choice D reason: Measuring blood pressure after exercise is not a good time for measuring blood pressure because it may reflect a temporary increase due to physical activity. Blood pressure should be measured after resting for at least 5 minutes in a quiet and comfortable environment.

Correct Answer is C
Explanation
Choice Areason: Graham crackers are made from wheat flour, which contains gluten. Peanut butter is a good source of fat and protein, but it may also contain traces of gluten from cross-contamination.
Choice Breason: Poached eggs are a good source of protein, but wheat bagel contains gluten, which is a protein found in wheat, barley, and rye. Gluten can damage the small intestine and cause malabsorption, diarrhea, and abdominal pain in people with celiac disease.
Choice C reason: Rice cereal is gluten-free and a good source of carbohydrates. Sliced bananas are gluten-free and a good source of potassium, fiber, and vitamin C.
Choice D reason: Rye toast contains gluten, which can harm people with celiac disease. Herbal tea is gluten-free and can help with hydration, but it does not provide enough calories or nutrients.
Correct Answer is B
Explanation
Choice A reason: Consume ten percent of total calories from saturated fat is not a correct instruction for the DASH diet. The DASH diet recommends limiting saturated fat intake to less than six percent of total calories, as saturated fat can raise blood cholesterol and increase the risk of heart disease.
Choice B reason: Consume foods that are high in calcium is a correct instruction for the DASH diet. The DASH diet emphasizes eating foods that are rich in calcium, such as low-fat dairy products, leafy green vegetables, and fortified cereals. Calcium helps regulate blood pressure and prevent osteoporosis.
Choice C reason: Increase intake of refined carbohydrates is not a correct instruction for the DASH diet. The DASH diet advises reducing intake of refined carbohydrates, such as white bread, white rice, and sweets. Refined carbohydrates can increase blood sugar and insulin levels and contribute to obesity and diabetes.
Choice D reason: Limit sodium intake to 3,200 milligrams per day is not a correct instruction for the DASH diet. The DASH diet recommends limiting sodium intake to less than 2,300 milligrams per day, or even lower to 1,500 milligrams per day for some people. Sodium can increase blood pressure and fluid retention and damage the kidneys and blood vessels.
