What should the nurse assess the patient for after discontinuing the TPN?

Hypoglycemia.

Hyperthermia.

Flatulence.

Tachycardia.

Answer and Explanation

The Correct Answer is A

Choice A rationale

Abrupt cessation of total parenteral nutrition (TPN) can lead to a rapid decrease in blood glucose levels. While receiving TPN, the body is continuously supplied with glucose. When this external glucose source is suddenly removed, the pancreas may continue to secrete insulin at a rate higher than needed, resulting in hypoglycemia. Signs and symptoms of hypoglycemia include sweating, tremors, confusion, and dizziness.

Choice B rationale

Hyperthermia, or elevated body temperature above the normal range of approximately 36.5°C to 37.5°C (97.7°F to 99.5°F), is not a typical complication following the discontinuation of TPN. Fever is usually associated with infection or inflammation, neither of which are a direct consequence of stopping TPN.

Choice C rationale

Flatulence, or the accumulation of gas in the digestive tract leading to bloating and the passage of gas, is related to dietary intake and digestive processes. Discontinuing TPN, which bypasses the digestive system, would not directly cause an increase in flatulence. In fact, digestive issues might improve once oral or enteral feeding resumes.

Choice D rationale

Tachycardia, an abnormally rapid heart rate (typically defined as above 100 beats per minute in adults), is not a direct physiological consequence of discontinuing TPN. While changes in fluid balance or electrolyte levels (which can occur with TPN but are monitored closely) could indirectly affect heart rate, hypoglycemia is a more immediate and direct risk upon TPN cessation.

Correct Answer is B

Explanation

Choice A rationale

While saturated fats are part of the body's metabolic processes, their primary negative impact at elevated levels isn't directly interfering with the overall metabolic pathways in a disruptive manner. The issue lies more specifically with their influence on lipid profiles rather than a broad metabolic dysfunction.

Choice B rationale

Saturated fats, primarily found in animal products, have been shown to increase low-density lipoprotein (LDL) cholesterol levels in the blood. Elevated LDL cholesterol is a major risk factor for atherosclerosis, a condition where plaque builds up in the arteries, narrowing them and increasing the risk of heart disease and stroke.

Choice C rationale

Hydrogenation is a process used to solidify unsaturated fats, creating trans fats, which are even more detrimental to cholesterol levels than saturated fats. Saturated fats themselves are naturally solid at room temperature and do not inherently need to be hydrogenated to achieve this state.

Choice D rationale

Saturated fats do not typically block the absorption of essential nutrients. The digestive system is designed to absorb a variety of fats, including saturated fats, along with other nutrients. The primary concern with high intake of saturated fats is their negative impact on blood lipid levels.

Correct Answer is ["1610"]

Explanation

Step 1: Convert ounces to milliliters for oral intake. 8 ounces of coffee × 30 mL/ounce = 240 mL. 3 ounces of juice × 30 mL/ounce = 90 mL. 12 ounces of soda × 30 mL/ounce = 360 mL.

Step 2: Calculate the amount of water consumed from the pitcher. Initial amount - Remaining amount = Consumed amount. 800 mL - 200 mL = 600 mL.

Step 3: Calculate the total oral fluid intake. Coffee + Juice + Soda + Water = Total oral intake. 240 mL + 90 mL + 360 mL + 600 mL = 1290 mL.

Step 4: Calculate the total IV fluid intake over 8 hours. IV rate × Time = Total IV fluid. 40 mL/hour × 8 hours = 320 mL.

Step 5: Calculate the total fluid intake (oral + IV). Total oral intake + Total IV fluid = Total intake. 1290 mL + 320 mL = 1610 mL.

The nurse should document 1610 mL as the client's total intake for the shift.
