Rationale: The correct instruction for cord care is to keep the cord stump dry until it falls off. This helps prevent infection and promotes healing.
Choice A is incorrect because the timing of when the cord stump falls off can vary, usually between 1-3 weeks.
Choice B is incorrect as a black cord stump can be a normal part of the healing process, so it is unnecessary to contact the provider for this reason.
Choice C is incorrect because cleaning the cord with hydrogen peroxide daily is not recommended as it can delay healing and cause irritation.

Correct Answer: D

Rationale: Elevating the client's right arm on a pillow is essential post-mastectomy to reduce swelling and promote circulation. Placing the client in the supine position may not be comfortable or ideal after a mastectomy. Encouraging the client to lift objects with the right arm can strain the surgical site and hinder healing. Measuring the client's blood pressure on the right arm should be avoided to prevent disruption to the area and inaccurate readings.

Correct Answer: A

Rationale: The correct answer is A. Clients prescribed lithium need regular monitoring of blood levels to ensure the medication's effectiveness and safety. This monitoring helps to keep the medication within the therapeutic range and prevent toxicity.
Choice B is incorrect because lithium is usually taken with food to minimize gastrointestinal side effects.
Choice C is not directly related to lithium therapy; however, excessive sodium intake can affect lithium levels.
Choice D is incorrect as abruptly stopping lithium can lead to adverse effects and should only be done under healthcare provider guidance.

Correct Answer: B

Rationale: The correct answer is B: "Avoid foods that are high in fat." Clients with IBS should avoid foods high in fat as they can exacerbate symptoms such as abdominal pain, bloating, and diarrhea. High-fiber foods, choice A, can sometimes worsen symptoms in individuals with IBS. Increasing intake of dairy products, choice C, may also worsen symptoms for some individuals with IBS, especially if they are lactose intolerant. Drinking carbonated beverages, choice D, can contribute to bloating and gas, making symptoms worse for individuals with IBS.

Correct Answer: C

Rationale: The correct answer is C. Pain in the right shoulder after a cholecystectomy is common due to residual gas from the procedure.

Choices A, B, and D are incorrect. It is important to avoid heavy lifting for a longer period than just 1 week to prevent complications. Resuming usual activities after 2 weeks may not be appropriate depending on the individual's recovery. Following a low-protein diet is not a standard recommendation post-cholecystectomy.
