A nurse is about to replace a nearly depleted container of total parenteral nutrition (TPN) for a patient, but discovers a delay in the delivery of the new TPN solution from the pharmacy.
Which solution should the nurse administer until the next TPN solution is available?

0.9% sodium chloride.

Dextrose 10% in water.

3% sodium chloride.

Lactated Ringer’s.

Answer and Explanation

The Correct Answer is B

Choice A rationale

0.9% sodium chloride, also known as normal saline, is an isotonic solution that is commonly used for hydration and to replace lost fluids. However, it does not provide any calories or nutrients, which are necessary for patients receiving TPN1.

Choice B rationale

Dextrose 10% in water (D10W) is the recommended solution to administer until the next TPN solution is available. This is a hypertonic fluid that provides dextrose to the patient, helping to maintain their blood glucose levels and reducing the risk of hypoglycemia.

Choice C rationale

3% sodium chloride is a hypertonic saline solution that is typically used to treat patients with severe hyponatremia (low sodium levels). It is not suitable as a replacement for TPN as it does not provide the necessary nutrients and can lead to hypernatremia (high sodium levels) if used inappropriately.

Choice D rationale

Lactated Ringer’s solution is an isotonic solution that is commonly used for fluid resuscitation in patients with significant fluid loss. While it does contain multiple electrolytes that mimic those found in plasma, it does not provide any calories or nutrients, making it unsuitable as a replacement for TPN1.

Correct Answer is A

Explanation

Choice A rationale: Wet-to-dry dressings are a form of mechanical debridement. This method involves applying a wet dressing to the wound and allowing it to dry. When the dressing is removed, it also removes some of the dead or damaged tissue from the wound, helping to clean the wound and promote healing. This method can be painful and is not selective, meaning it can also remove healthy tissue. However, it is often used for wounds with a large amount of debris or necrotic tissue.

Choice B rationale: Surgical debridement is another method of wound debridement, but it is not a form of mechanical debridement. This method involves using surgical instruments to remove dead or damaged tissue. It is the fastest method of debridement and is often used for wounds that are infected or have a large amount of necrotic tissue. However, it requires a skilled practitioner and can be painful.

Choice C rationale: Enzymatic debridement involves applying a topical ointment that contains enzymes to the wound. These enzymes help to break down dead or damaged tissue. This method is selective and only removes necrotic tissue, leaving healthy tissue intact. However, it is not a form of mechanical debridement.

Choice D rationale: Autolytic debridement is a method that uses the body’s own enzymes and moisture to break down dead or damaged tissue. This is the slowest method of debridement but is also the least painful and is selective for necrotic tissue. Like enzymatic debridement, autolytic debridement is not a form of mechanical debridement.

A. Constipation B. Diarrhea C. Electrolyte imbalance D. Delayed gastric emptying

Correct Answer is B

Explanation

Choice A rationale

Constipation is not typically resolved by diluting enteral feeding formula.

Choice B rationale

Diarrhea can be a common side effect of enteral feeding, and diluting the formula can help manage this.

Choice C rationale

While electrolyte imbalance can occur with enteral feeding, diluting the formula is not typically done to resolve this issue.

Choice D rationale

Delayed gastric emptying is not typically resolved by diluting enteral feeding formula.
