A nurse is caring for a client who has a small-bore jejunostomy tube and is receiving a continuous tube feeding with a high-viscosity formula. Which of the following actions should the nurse take to prevent the tubing from clogging?
Administer the feeding by gravity drip.
Flush the tubing with 10 mL water every 6 hr.
Replace the bag and tubing every 24 hr.
Heat the formula prior to infusion.
The Correct Answer is B
Choice A reason: Administering the feeding by gravity drip is not an appropriate action for a client who has a small-bore jejunostomy tube and is receiving a high-viscosity formula. Gravity drip can cause overfeeding, aspiration, and abdominal distension. The nurse should use an infusion pump to regulate the flow rate and volume of the feeding.
Choice B reason: Flushing the tubing with 10 mL water every 6 hr is an appropriate action for a client who has a small-bore jejunostomy tube and is receiving a high-viscosity formula. Flushing the tubing prevents clogging, maintains patency, and hydrates the client. The nurse should also flush the tubing before and after medication administration, and whenever the feeding is interrupted or discontinued.
Choice C reason: Replacing the bag and tubing every 24 hr is not an appropriate action for a client who has a small-bore jejunostomy tube and is receiving a high-viscosity formula. Replacing the bag and tubing every 24 hr does not prevent clogging, and may increase the risk of infection and contamination. The nurse should replace the bag and tubing every 48 hr, or as per facility policy.
Choice D reason: Heating the formula prior to infusion is not an appropriate action for a client who has a small-bore jejunostomy tube and is receiving a high-viscosity formula. Heating the formula can alter its composition, reduce its nutritional value, and increase the risk of bacterial growth. The nurse should use room-temperature formula and store it in a refrigerator when not in use.

Correct Answer is A
Explanation
Choice A reason: Vitamin D is a fat-soluble vitamin that is essential for bone health, immune function, and calcium absorption. It is mainly obtained from exposure to sunlight and animal sources, such as dairy products, eggs, and fish. Vegans are at risk for vitamin D deficiency, especially if they live in areas with limited sunlight or do not take supplements.
Choice B reason: Vitamin C is a water-soluble vitamin that is important for collagen synthesis, wound healing, and antioxidant activity. It is abundant in plant sources, such as fruits and vegetables. Vegans are not likely to be deficient in vitamin C, unless they have a very restricted diet or a malabsorption disorder.
Choice C reason: Magnesium is a mineral that is involved in many enzymatic reactions, muscle contraction, nerve transmission, and bone formation. It is widely distributed in plant and animal foods, such as nuts, seeds, legumes, grains, and green leafy vegetables. Vegans are not prone to magnesium deficiency, unless they have a chronic condition that affects magnesium absorption or excretion.
Choice D reason: Folic acid is a water-soluble vitamin that is essential for DNA synthesis, cell division, and red blood cell production. It is found in fortified grains, cereals, breads, and pasta, as well as in dark green leafy vegetables, beans, and lentils. Vegans are not at risk for folic acid deficiency, as long as they consume enough of these foods or take supplements.
Correct Answer is B
Explanation
Choice A reason: Flossing dentures is not necessary, as dentures do not have spaces between the teeth where plaque and food particles can accumulate. Flossing dentures may damage the denture material or cause it to loosen.
Choice B reason: Dentures should be cleaned with a soft material to prevent scratches or damage. A washcloth is gentle enough to clean the denture surfaces without causing harm.
Choice C reason: Wiping dentures before storing them in a dry container at night is not advisable, as it may cause the dentures to crack or warp. Dentures should be soaked in water or a denture cleanser solution overnight to keep them moist and prevent them from losing their shape.
Choice D reason: Wrapping gloved fingers with gauze to remove dentures is not a standard practice. Dentures should be removed carefully by rocking them slightly to break the seal with the gums. Using gauze is unnecessary and may not be as effective or safe for the dentures or the oral tissues.
