A nurse is evaluating the effectiveness of IV fluid therapy for a client who has dehydration. Which of the following findings indicates improvement?

Decreased urine specific gravity.

Increased hematocrit level.

Decreased skin turgor.

Increased serum osmolarity.

Answer and Explanation

The Correct Answer is A

Choice A reason:

Decreased urine specific gravity indicates improvement in hydration status. Urine specific gravity is a measure of the concentration of solutes in the urine. It reflects the ability of the kidney to concentrate or dilute urine. A high urine specific gravity (>1.030) indicates concentrated urine, which can be caused by dehydration, reduced renal blood flow, or increased fluid loss. A low urine specific gravity (<1.010) indicates diluted urine, which can be caused by overhydration, diuretic use, or impaired renal function. A normal urine specific gravity ranges from 1.010 to 1.030.

Choice B reason:

Increased hematocrit level indicates worsening of dehydration. Hematocrit is the percentage of red blood cells in the total blood volume. It is affected by the plasma volume and the number of red blood cells. A high hematocrit (>47% for males and >42% for females) indicates hemoconcentration, which can be caused by dehydration, polycythemia, or hypoxia. A low hematocrit (<37% for males and <32% for females) indicates hemodilution, which can be caused by overhydration, anemia, or hemorrhage. A normal hematocrit ranges from 37% to 47% for males and 32% to 42% for females.

Choice C reason:

Decreased skin turgor indicates persistent dehydration. Skin turgor is the elasticity of the skin that reflects its hydration status. It is assessed by pinching a fold of skin on the chest, abdomen, or forearm and releasing it. Normally, the skin should return to its original position in less than 3 seconds. If the skin remains elevated or takes longer to return, it indicates poor skin turgor, which can be caused by dehydration, aging, or edema.

Choice D reason:

Increased serum osmolarity indicates worsening of dehydration. Serum osmolarity is a measure of the concentration of solutes in the blood plasma. It reflects the balance between water and electrolytes in the body fluids. A high serum osmolarity (>300 mOsm/kg) indicates hyperosmolarity, which can be caused by dehydration, hypernatremia, hyperglycemia, or mannitol infusion. A low serum osmolarity (<280 mOsm/kg) indicates hypoosmolarity, which can be caused by overhydration, hyponatremia, syndrome of inappropriate antidiuretic hormone secretion (SIADH), or diuretic use. A normal serum osmolarity ranges from 280 to 300 mOsm/kg.

Correct Answer is ["A","B"]

Explanation

Choice A reason:

Furosemide is a potassium-wasting diuretic that may reduce the potassium level in your blood. To counteract the loss of potassium, you should try to eat enough potassium-rich foods in your diet. Some examples of potassium-rich foods include bananas, orange juice, apricots, acorn squash, butternut squash, Hubbard squash, prunes, raisins, and bran products.

Choice B reason:

Furosemide is used to treat high blood pressure and edema by causing the kidneys to get rid of unneeded water and salt from the body into the urine. To enhance the effect of furosemide and prevent fluid retention, you should decrease intake of foods high in sodium. Some examples of sodium-rich foods include processed meats, canned soups, pickles, cheese, salted nuts, and snack foods.

Choice C reason:

Furosemide does not affect the calcium level in your blood significantly. Therefore, there is no need to increase intake of foods high in calcium when taking furosemide. However, you should still consume adequate amounts of calcium for your bone health and other functions. Some examples of calcium-rich foods include milk, yogurt, cheese, broccoli, kale, and fortified cereals.

Choice D reason:

Furosemide does not affect the protein level in your blood significantly. Therefore, there is no need to decrease intake of foods high in protein when taking furosemide. However, you should still consume moderate amounts of protein for your muscle health and other functions. Some examples of protein-rich foods include eggs, fish, poultry, meat, beans, nuts, and seeds.

Choice E reason:

Furosemide can cause dehydration and electrolyte imbalance by increasing urine output. Therefore, you should increase intake of fluids as tolerated to prevent these complications. You should drink enough water to keep your urine clear or pale yellow. You should also avoid alcohol and caffeine as they can worsen dehydration.

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.
