A nurse is preparing to administer three liquid medications to a client who has an NG feeding tube with continuous enteral feedings. Which of the following actions should the nurse take?

Correct Answer: D

Rationale: The correct answer is D: Flush the NG feeding tube with 30 mL of water immediately following medication administration. This is important to ensure that the medications are completely delivered into the client's system and to prevent any potential clogging of the feeding tube. Flushing with water helps clear any residual medication in the tube, maintaining its patency. A: Mixing the medications together is not recommended as it may alter the effectiveness of each individual medication. B: Diluting each medication with tap water is not necessary and may dilute the medication's concentration, affecting its effectiveness. C: Maintaining the head of the bed flat for 30 min following medication administration is not directly related to the proper administration of medications through an NG tube.

Correct Answer: C

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.

Correct Answer: C

Rationale: The correct answer is C: vitamins. Vitamins are absorbed in the GI tract without being digested because they are already in a form that can be easily absorbed by the body. Unlike starch, proteins, and triglycerides which require digestion by enzymes to break them down into smaller molecules for absorption, vitamins are typically small molecules that can be directly absorbed into the bloodstream. Therefore, vitamins do not undergo digestion in the GI tract and are absorbed as they are. Starch, proteins, and triglycerides require digestion to be broken down into their respective components before they can be absorbed.

Correct Answer: A

Rationale: The correct answer is A: opening into the oropharynx. The fauces are the opening at the back of the mouth that leads into the oropharynx, connecting the mouth to the throat. This is where food and liquid pass through when swallowing. Choices B, C, and D are incorrect because the fauces specifically refer to the opening into the oropharynx, not the space between the cheek and gums, the cavity containing the tongue and teeth, or the opening into the larynx.

Correct Answer: A

Rationale: The correct answer is A because the esophagus contains skeletal muscles at the superior end (upper part) for voluntary control during swallowing and smooth muscles at the inferior end (lower part) for involuntary peristalsis to move food to the stomach. This arrangement allows for both conscious and unconscious control of food movement. Now, let's analyze why the other choices are incorrect: B: The esophagus does have a tunica submucosa, which is important for support and nourishment of the mucosa. C: Villi and microvilli are found in the small intestine, not the esophagus, and they increase surface area for nutrient absorption. D: The esophagus does have a tunica mucosa, which contains mucous glands to aid in lubrication and protection of the lining.
