A nurse is reviewing the laboratory report of a client who has diabetic ketoacidosis (DKA) Which of the following findings should the nurse expect?

Serum glucose 600 mg/dL.

Serum bicarbonate 28 mEq/L.

Serum potassium 2.5 mEq/L.

Serum sodium 150 mEq/L.

Answer and Explanation

The Correct Answer is A

Choice A reason:

Serum glucose 600 mg/dL. This is an expected finding for a client who has diabetic ketoacidosis (DKA) DKA results from a deficiency of insulin, which leads to hyperglycemia and ketosis. The normal range for serum glucose is 70 to 110 mg/dL.

Choice B reason:

Serum bicarbonate 28 mEq/L. This is not an expected finding for a client who has DKA. A client who has DKA experiences ketosis, which results in ketones in the urine and blood. The nurse should expect a client who has DKA to have an HCO3- less than 15 mEq/L. This decreased value is due to an increased production of ketones, which results in metabolic acidosis. The normal range for serum bicarbonate is 22 to 26 mEq/L.

Choice C reason:

Serum potassium 2.5 mEq/L. This is not an expected finding for a client who has DKA. A client who has DKA experiences osmotic diuresis and subsequent dehydration, which can cause electrolyte imbalances. The nurse should expect a client who has DKA to have elevated serum potassium levels due to the movement of potassium from the intracellular to the extracellular space in response to acidosis. The normal range for serum potassium is 3.5 to 5 mEq/L.

Choice D reason:

Serum sodium 150 mEq/L. This is not an expected finding for a client who has DKA. A client who has DKA experiences osmotic diuresis and subsequent dehydration, which can cause electrolyte imbalances. The nurse should expect a client who has DKA to have decreased serum sodium levels due to the dilutional effect of excess glucose in the blood. The normal range for serum sodium is 136 to 145 mEq/L.

Correct Answer is C

Explanation

Choice A reason: This is incorrect because 0.9% sodium chloride (normal saline) is an isotonic solution, not a hypotonic one. Isotonic solutions have the same concentration of solutes as blood plasma and do not cause fluid movement across the cell membrane.

Choice B reason:

This is incorrect because 0.9% sodium chloride (normal saline) is an isotonic solution, not a hypertonic one. Hypertonic solutions have a higher concentration of solutes than blood plasma and cause fluid to move out of the cells and into the vascular space.

Choice C reason:

This is correct because 0.9% sodium chloride (normal saline) is an isotonic solution that will expand the vascular space by adding fluid without changing the concentration of solutes. This is useful for patients with hyponatremia (low sodium level in the blood) who need to restore their fluid and electrolyte balance.

Choice D reason:

This is incorrect because 0.9% sodium chloride (normal saline) is an isotonic solution that will expand the vascular space by adding fluid without changing the concentration of solutes. It will not have no effect on fluid movement, as it will increase the intravascular volume.

A. Cheese. B. Broccoli. C. Almonds. D. Bananas. E. Sardines.

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.
