A nurse is assisting in the selection of food for a client who has hyperkalemia. Which of the following foods should the nurse avoid selecting as it contains the greatest amount of potassium?
1 cup of brown rice
One medium raw tomato
1 oz of cheddar cheese
One small baked potato
The Correct Answer is D
Choice A reason: 1 cup of brown rice contains about 84 mg of potassium, which is low compared to other foods.
Choice B reason: One medium raw tomato contains about 292 mg of potassium, which is moderate compared to other foods.
Choice C reason: 1 oz of cheddar cheese contains about 28 mg of potassium, which is very low compared to other foods.
Choice D reason: One small baked potato contains about 738 mg of potassium, which is very high compared to other foods. Potassium is important for nerve and muscle function, but too much can cause irregular heartbeat, muscle weakness, and nausea.

Correct Answer is B
Explanation
Choice A reason: Dry eyes are not caused by vitamin D deficiency, but by other factors such as aging, medication, environmental conditions, or eye diseases. Vitamin D does not have a direct role in eye health or function.
Choice B reason: Fractures are caused by vitamin D deficiency, as vitamin D helps the body absorb calcium, which is essential for bone health and strength. Vitamin D deficiency can lead to osteoporosis, a condition in which the bones become brittle and prone to breaking.
Choice C reason: Infection is not caused by vitamin D deficiency, but by other factors such as exposure to pathogens, weakened immune system, or poor hygiene. Vitamin D may have some role in modulating immune responses, but it is not a primary factor in preventing infection.
Choice D reason: Swelling is not caused by vitamin D deficiency, but by other factors such as injury, inflammation, fluid retention, or allergic reaction. Vitamin D does not have a direct role in regulating fluid balance or reducing inflammation.
Correct Answer is C
Explanation
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.
