A nurse is teaching a client who is on a low-sodium diet. Which of the following instructions should the nurse include? (Select all that apply.)

Limit intake of canned soups.

Choose botled salad dressings.

Choose diet sodas over botled water.

Replace processed meats with fresh meat products.

Read labels on foods before eating.

Answer and Explanation

Correct Answer : A,D,E

Choice A: Limit intake of canned soups is correct because canned soups are high in sodium and can increase blood
pressure and ﬂuid retention. The nurse should advise the client to choose low-sodium or homemade soups instead.

Choice B: Choose botled salad dressings is incorrect because botled salad dressings are also high in sodium and can have added sugars and fats. The nurse should advise the client to make their own salad dressings with vinegar, oil, herbs, and spices.

Choice C: Choose diet sodas over botled water is incorrect because diet sodas are not a healthy alternative to water. Diet sodas contain artificial sweeteners, caﬀeine, and phosphoric acid, which can aﬀect the body's pH balance and calcium absorption. The nurse should advise the client to drink plain water or ﬂavored water with natural ingredients.

Choice D: Replace processed meats with fresh meat products is correct because processed meats such as bacon, ham, sausage, and hot dogs are high in sodium and preservatives. The nurse should advise the client to choose fresh meat products such as chicken, turkey, fish, or lean beef.

Choice E: Read labels on foods before eating is correct because reading labels can help the client identify the sodium content and other ingredients in foods. The nurse should advise the client to look for foods that have less than 140 mg of sodium per serving and avoid foods that have salt, sodium, or monosodium glutamate (MSG) in the ingredient list.

Correct Answer is D

Explanation

Choice A: 18 mg/dL is incorrect because it is within the normal range of BUN, which is 7 to 20 mg/dL. BUN stands for blood urea nitrogen, which is a measure of the amount of nitrogen in the blood that comes from urea, a waste product of protein metabolism. BUN can reﬂect the kidney function and hydration status of the client.

Choice B: 10 mg/dL is incorrect because it is also within the normal range of BUN. A low BUN level can indicate liver problems, malnutrition, or overhydration.

Choice C: 13 mg/dL is incorrect because it is also within the normal range of BUN. A normal BUN level does not necessarily rule out dehydration, as other factors such as diet, medications, and blood loss can aﬀect the BUN level.

Choice D: 25 mg/dL is correct because it is above the normal range of BUN and indicates a high BUN level. A high BUN level can indicate dehydration, kidney failure, urinary tract obstruction, heart failure, or excessive protein intake. The nurse should report this value to the provider as it may require further evaluation and treatment.

A. PaCO2 50 mm Hg B. HCO3 30 mEq/L C. pH 7.45 D. Potassium 3.3 mEq/L

Correct Answer is A

Explanation

The correct answer is a) PaCO2 50 mm Hg. This is because respiratory acidosis is a condition in which the lungs cannot remove enough carbon dioxide from the blood, resulting in a high level of PaCO2. The normal range of PaCO2 is 35 to 45 mm Hg.

Choice b) HCO3 30 mEq/L is incorrect because this is a normal value for bicarbonate, which is a buﬀer that helps maintain the acid-base balance in the blood. The normal range of HCO3 is 22 to 26 mEq/L.

Choice c) pH 7.45 is incorrect because this is a normal value for the acidity or alkalinity of the blood. The normal range of pH is 7.35 to 7.45. Respiratory acidosis causes a low pH, indicating acidemia.

Choice d) Potassium 3.3 mEq/L is incorrect because this is a low value for potassium, which is an electrolyte that helps regulate nerve and muscle function, ﬂuid balance, and blood pressure. The normal range of potassium is 3.5 to 5.0 mEq/L. Respiratory acidosis can cause hyperkalemia, or high potassium levels, due to the shift of hydrogen ions into cells and potassium out of cells.
