A nurse is assisting with teaching a class about nutrients.
The nurse should include that which of the following is a function of fats?
Regulates nerve cell transmission.
Converts to sugar to provide energy.
Facilitates the absorption of vitamins.
Builds and repairs tissue.
The Correct Answer is C
Choice A rationale
Regulating nerve cell transmission is primarily a function of electrolytes like sodium, potassium, and calcium, as well as neurotransmitters. While fats are components of nerve cell membranes, they do not directly regulate the transmission of nerve impulses.
Choice B rationale
Converting to sugar (glucose) to provide energy is the primary function of carbohydrates. While fats can be metabolized for energy, they are broken down into fatty acids and glycerol, not directly into glucose. Gluconeogenesis can convert glycerol to glucose, but this is a secondary energy pathway.
Choice C rationale
Fats are crucial for the absorption of fat-soluble vitamins (A, D, E, and K). These vitamins are lipophilic, meaning they dissolve in fats. Dietary fat is necessary in the small intestine to emulsify these vitamins, allowing them to be absorbed across the intestinal lining into the bloodstream.
Choice D rationale
Building and repairing tissue is the primary function of proteins, which are composed of amino acids. While fats are components of cell membranes and contribute to overall cell structure, they do not play the main role in tissue synthesis and repair.

Correct Answer is D
Explanation
Choice A rationale
Securing the tube and retesting the pH in one hour is insufficient to confirm correct placement. While a pH of 3 suggests gastric placement (normal gastric pH is typically 1.5 to 3.5), it doesn't definitively rule out placement in the respiratory tract or intestines, as these can occasionally have acidic pH levels. Delaying definitive confirmation could lead to serious complications if the tube is misplaced.
Choice B rationale
Inserting the tube an additional 1-2 inches and retesting the pH is not a reliable method for confirming placement. Advancing the tube further without radiographic confirmation could increase the risk of trauma to the gastrointestinal tract or even pulmonary aspiration if the initial placement was incorrect. pH testing alone is not conclusive.
Choice C rationale
Auscultating for the "swoosh" of air while injecting air into the NG tube is an outdated and unreliable method for confirming placement. The sound can be misleading and may be heard even if the tube is incorrectly positioned in the esophagus or lungs. This method does not provide definitive proof of gastric placement and poses a risk of aspiration.
Choice D rationale
Obtaining an x-ray is the gold standard for confirming nasogastric tube placement. Radiographic imaging allows for direct visualization of the tube's trajectory and ensures that the distal tip is correctly positioned in the stomach or duodenum. This method provides the most accurate and reliable confirmation, minimizing the risk of complications such as aspiration or misadministration of feedings and medications.
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.
