Correct Answer is ["A","C","E"]

Explanation

Choice A reason:

Cheese is a good source of calcium, which is essential for bone health and muscle contraction. Calcium also helps regulate the heart rhythm and blood clotting. Cheese can provide about 200 mg of calcium per ounce.

Choice B reason:

Broccoli is a cruciferous vegetable that contains goitrogens, which are substances that can interfere with thyroid hormone synthesis and cause or worsen hypothyroidism. Hypothyroidism can lead to low levels of parathyroid hormone (PTH), which is responsible for maintaining calcium balance in the body. Therefore, broccoli should be avoided or limited by clients who have hypocalcemia due to hypoparathyroidism.

Choice C reason:

Almonds are rich in magnesium, which is a mineral that helps regulate calcium absorption and metabolism. Magnesium also plays a role in nerve and muscle function, blood pressure, and blood sugar control. Almonds can provide about 80 mg of magnesium per ounce.

Choice D reason:

Bananas are high in potassium, which is a mineral that can affect the balance of calcium in the body. High levels of potassium can cause hyperkalemia, which can lower the serum calcium level by increasing the renal excretion of calcium and decreasing the release of PTH. Therefore, bananas should be avoided or limited by clients who have hypocalcemia due to hypoparathyroidism.

Choice E reason:

Sardines are a type of oily fish that contain vitamin D, which is a fat-soluble vitamin that helps increase the intestinal absorption of calcium and phosphorus. Vitamin D also works with PTH to regulate the bone resorption and formation of calcium. Sardines can provide about 250 IU of vitamin D per 3 ounces.

A. Administer magnesium sulfate IV. B. Monitor the client's blood pressure and heart rate. C. Encourage the client to increase intake of green leafy vegetables. D. Prepare to administer calcium gluconate IV. E. Assess the client for Chvostek's sign and Trousseau's sign.

Correct Answer is ["A","C","E"]

Explanation

Choice A reason:

Administer magnesium sulfate IV. This is correct because magnesium sulfate is the treatment of choice for severe hypomagnesemia. It can rapidly increase the blood level of magnesium and correct the symptoms of deficiency.

Choice B reason:

Monitor the client's blood pressure and heart rate. This is incorrect because monitoring vital signs is not a specific intervention for hypomagnesemia. However, it is important to monitor the client for signs of hypotension and bradycardia, which can occur as adverse effects of magnesium sulfate therapy.

Choice C reason:

Encourage the client to increase intake of green leafy vegetables. This is correct because green leafy vegetables are rich sources of dietary magnesium. Increasing the intake of magnesium-rich foods can help prevent or treat mild hypomagnesemia.

Choice D reason:

Prepare to administer calcium gluconate IV. This is incorrect because calcium gluconate is not indicated for hypomagnesemia. Calcium gluconate is used to treat hypocalcemia, which can occur as a complication of hypomagnesemia. However, calcium gluconate should not be given until the magnesium level is corrected, as low magnesium can impair the response to calcium.

Choice E reason:

Assess the client for Chvostek's sign and Trousseau's sign. This is correct because Chvostek's sign and Trousseau's sign are clinical tests for neuromuscular irritability, which can occur in hypomagnesemia. Chvostek's sign is elicited by tapping the facial nerve in front of the ear and observing for facial twitching. Trousseau's sign is elicited by inflating a blood pressure cuff above the systolic pressure for 3 minutes and observing for carpal spasm.
