The nurse is caring for a patient who has a temporary percutaneous dialysis catheter in

Correct Answer: D

Rationale: The correct answer is D because assessing the catheter site for redness and swelling is crucial in monitoring for signs of infection, which is a common complication with percutaneous dialysis catheters. This step helps in early detection and prompt intervention to prevent further complications. Incorrect choices: A: This choice is too vague and does not provide specific guidance on catheter care. B: Applying a sterile gauze dressing is important, but it is not the most critical step in caring for a percutaneous dialysis catheter. C: Replacing the transparent dressing every 10 days is not recommended as it may increase the risk of infection due to unnecessary manipulation of the catheter site.

Correct Answer: D

Rationale: Correct Answer: D Rationale: 1. Body fluids consist of water and solutes dissolved in it, such as ions, proteins, and other molecules. 2. Referring to body fluids as 'body water' would not account for the presence of solutes in the fluids. 3. It is essential to acknowledge that body fluids are a combination of water and various dissolved substances. 4. By recognizing that body fluids are water plus solutes, the complexity and composition of these fluids are accurately represented. Summary of other choices: A. Incorrect. Internal body cavities are still considered part of the body, so this does not explain why 'body water' is inaccurate. B. Incorrect. Sweat is still a body fluid that contains water and solutes, so this does not address the inaccuracy in the term 'body water.' C. Incorrect. While some body fluids may contain lipids, not all body fluids are lipid-based, so this does not explain the inaccuracy of the term '

Correct Answer: B

Rationale: When isotonic fluid is added to the ECF, the concentration of solutes in the ECF remains the same as the ICF. Thus, there will be no osmotic gradient to drive fluid movement between the ECF and ICF, resulting in no net fluid shift. Option A is incorrect because in an isotonic solution, there is no concentration gradient to drive fluid from ICF to ECF. Option C is incorrect as fluid will not shift from ECF to ICF due to the isotonic nature of the added fluid. Option D is incorrect as adding isotonic fluid does not affect solute movement between the ECF and ICF. Thus, the correct answer is B.

Correct Answer: C

Rationale: Step 1: The body produces H+ ions through metabolic processes like nutrient breakdown and intermediary metabolism. Step 2: O2 is not a direct source of H+ production in the body. Step 3: O2 is involved in cellular respiration but does not directly generate H+ ions. Step 4: CO2 can indirectly lead to H+ production through carbonic acid formation. Step 5: Therefore, the correct answer is C: O2, as it is not a direct source of H+ production in the body.

Correct Answer: A

Rationale: The correct answer is A: Desmopressin acetate (DDAVP). Desmopressin is a synthetic analogue of vasopressin that acts on the kidneys to increase water reabsorption, reducing urine output in diabetes insipidus. This medication helps to concentrate the urine and restore fluid balance in hypovolemic patients. Choice B: Benadryl is an antihistamine with anticholinergic properties and is not indicated for treating diabetes insipidus. Choice C: Calcium gluconate is used to treat calcium deficiencies and has no role in managing diabetes insipidus. Choice D: Prednisone is a corticosteroid used for its anti-inflammatory properties and is not the appropriate treatment for diabetes insipidus. In summary, Desmopressin (DDAVP) is the correct choice as it directly targets the underlying cause of diabetes insipidus by promoting water reabsorption in the
