A nurse is teaching a client who has chronic kidney disease about limiting foods that are high in potassium. Which of the following foods should the nurse instruct the client to avoid? (Select all that apply)
Raisins
Asparagus
Bananas
Tomatoes
Green Beans
Correct Answer : A,C,D
Choice A reason:
Raisins are dried grapes and are known to have a higher concentration of nutrients, including potassium. For individuals with chronic kidney disease (CKD), consuming foods like raisins that are high in potassium can lead to hyperkalemia, a condition where potassium levels in the blood are higher than normal. This can be dangerous as it may cause heart rhythm problems.
Choice B reason:
Asparagus is considered a lower-potassium food, making it a safer choice for people with CKD. It's important for individuals with CKD to manage their potassium intake, but asparagus can be included in their diet in appropriate portions.
Choice C reason:
Bananas are well-known for being rich in potassium. For someone with CKD, eating bananas can contribute to an excessive intake of potassium, which their kidneys may not be able to eliminate efficiently, potentially leading to hyperkalemia.
Choice D reason:
Tomatoes, including tomato products like sauces, juices, and purees, are high in potassium. Therefore, they should be limited or avoided in the diet of a person with CKD to prevent complications associated with high potassium levels.
Choice E reason:
Green beans are considered to be a lower-potassium vegetable. They can be included in a kidney-friendly diet, provided they are consumed in moderation and balanced with other dietary needs.

Correct Answer is C
Explanation
Choice A reason:
Kernig's sign is associated with meningitis and is not related to the symptoms of tingling sensations that can occur after a subtotal thyroidectomy. This sign is elicited by extending the client's leg at the knee while the hip is flexed, which would not be relevant in this case.
Choice B reason:
Brudzinski's sign is another indicator of meningitis and involves involuntary flexion of the hips and knees when attempting to flex the client's neck. Similar to Kernig's sign, it is not pertinent to the postoperative symptoms of a subtotal thyroidectomy.
Choice C reason:
Chvostek's sign is a clinical sign of existing neuromuscular irritability seen in hypocalcemia, which can occur after thyroid surgery due to accidental removal or damage to the parathyroid glands. Tapping on the facial nerve triggers twitching of the facial muscles, which correlates with the tingling sensations reported by the client.
Choice D reason:
Babinski's sign is used to assess neurological function, particularly of the central nervous system, and is not related to the symptoms of hypocalcemia. It involves stroking the sole of the foot to observe the toes' movements, which would not provide information about the tingling sensations the client is experiencing.
Correct Answer is B
Explanation
Choice A reason:
Placing the leg under a heat lamp every 3 hours is not recommended for the treatment of cellulitis. Heat lamps can cause burns and excessive drying of the skin, which may worsen the condition.
Choice B reason:
Wrapping a warm, wet towel around the affected area is a safe and effective way to apply heat therapy for cellulitis. It can help improve blood flow and relieve discomfort without the risk of burns associated with dry heat sources.
Choice C reason:
Using a heating pad directly on the skin, especially when lying down, can increase the risk of burns and is not recommended for treating cellulitis. Heating pads can provide uneven heat and may exacerbate swelling and inflammation.
Choice D reason:
Soaking the leg in water is not typically advised for cellulitis, especially if there are open wounds or breaks in the skin. Immersion in water can introduce new bacteria to the affected area and potentially worsen the infection.
