Correct Answer: C

Rationale: Water should be instilled into the feeding tube between administering the two medications to maintain the patency of the feeding tube and ensure that the total dose of medication enters the stomach and does not remain in the tube. These liquid medications do not need to be diluted when administered via a feeding tube. Mixing the medications in one syringe can lead to interactions or alterations in the medications' properties. Withdrawing any fluid from the tube before instilling each medication can cause inaccurate dosing and incomplete administration. Therefore, the correct action is to administer water between the doses of the two liquid medications to ensure proper delivery and avoid any complications.

Correct Answer: B

Rationale: Clients with cholecystitis, which is inflammation of the gallbladder, should follow a low-fat diet to reduce symptoms. Broiled fish, green beans, and an apple (Option B) is the most suitable choice as it is low in fat. Steak, baked beans, and a salad (Option A) provide a high amount of fat and protein, which may exacerbate symptoms of cholecystitis. Pork chops, macaroni and cheese, and grapes (Option C) and avocado salad, milk, and angel food cake (Option D) contain high-fat foods that are not recommended for individuals with cholecystitis. Therefore, Option B is the most appropriate choice for a client with cholecystitis.

Correct Answer: B

Rationale: The correct answer is the right cephalic vein. The cephalic vein is a large and superficial vein commonly used for IV access. Documenting the specific anatomic name of the vein used for IV access, such as the cephalic vein, is essential for accurate medical records. Option A, the left brachial vein, is incorrect as the brachial vein is too deep to be accessed for IV infusion. Option C, the dorsal side of the right wrist, is not a recommended IV access site due to fragile veins and potential pain for the patient. Option D, right upper extremity, is too broad and lacks the specificity necessary for precise documentation of the IV access site.

Correct Answer: D

Rationale: To ensure safe medication use, the nurse should encourage the client to call the clinic nurse or healthcare provider if any questions arise. This direct communication allows for personalized assistance and clarification tailored to the client's specific concerns. Providing Internet sites (Choice A) may lead to unreliable information, and a drug reference book (Choice B) may not address individualized questions. While the written instructions may contain information (Choice C), they may not cover all potential queries the client might have, making direct contact with the healthcare provider the most appropriate option.

Correct Answer: B

Rationale: To ensure optimal benefits from a metered-dose inhaler, the client should be instructed to compress the inhaler while slowly breathing in through the mouth. This technique facilitates the medication to reach deep into the lungs, allowing for an optimal bronchodilation effect. Option B is correct as it promotes the proper coordination of inhaler compression and inhalation, ensuring effective drug delivery. Options A, C, and D are incorrect as they do not support deep lung penetration of the medication, which is essential for its effectiveness in treating respiratory conditions.
