1. After teaching a client to increase dietary potassium intake, a nurse assesses the client's understanding. Which dietary meal selection indicates the client correctly understands the teaching?

Correct answer: C

Rationale: Choice C is the correct answer as it includes foods high in potassium, such as raisins, whole wheat toast, and milk. Potassium is essential for various bodily functions, including maintaining proper heart and muscle function. Choices A, B, and D do not contain significant sources of potassium. Choice A consists mainly of carbohydrates and sugar, choice B focuses on protein and carbohydrates, and choice D provides carbohydrates and some fruit but lacks high-potassium options like in choice C.

2. Your patient has the following arterial blood gas results: pH 7.26, PaCO2 28, HCO3 11 mEq/L. How would the nurse interpret the results?

Correct answer: D

Rationale: The given arterial blood gas results show a low pH, indicating acidosis, with normal pH range being 7.35 to 7.45. The low PaCO2 suggests alkalosis, while the low bicarb level indicates acidosis. In this scenario, the primary issue is the metabolic acidosis, as the pH bicarb relationship supports this. The compensatory response to metabolic acidosis is a decrease in PaCO2, leading to a respiratory alkalosis. Therefore, the correct interpretation is 'Metabolic acidosis with a compensatory respiratory alkalosis.' Choices A, B, and C are incorrect as they do not accurately reflect the relationship between the pH, PaCO2, and HCO3 levels in the arterial blood gas results provided.

3. When planning the care of a patient with a fluid imbalance, the nurse understands that in the human body, water and electrolytes move from the arterial capillary bed to the interstitial fluid. What causes this to occur?

Correct answer: D

Rationale:

4. Electrolytes:

Correct answer: D

Rationale: The correct answer is D. Electrolytes are substances that dissociate into ions when dissolved in water, allowing the solution to conduct electricity. Choice A is incorrect because glucose does not form electrolytes when added to water. Choice B is incorrect as it states that electrolytes dissociate but do not form ions, which is inaccurate as electrolytes do form ions in water solutions. Choice C is also incorrect as it states that electrolytes form ions but may not necessarily dissociate, which goes against the definition of electrolytes that must dissociate into ions for conductivity. Therefore, choice D is the most accurate as it correctly describes that electrolytes dissociate in water solutions and form ions, highlighting the essential characteristics of electrolytes.

5. A nurse preparing to start an IV on a newly admitted patient teaches the patient about the procedure and begins to prepare the site. The nurse should always start by:

Correct answer: C

Rationale: Before preparing the skin, the nurse should ask the patient if they are allergic to latex or iodine, which are commonly used in IV therapy setup. This is crucial to prevent potential allergic reactions at the IV site or even life-threatening anaphylaxis. Leaving one hand ungloved (choice A) is not a recommended practice as both hands should be gloved for infection control. While preparing the skin with an iodine solution (choice B) is a step in the process, ensuring the patient's safety by checking for allergies comes first. Removing excessive hair at the selected site (choice D) is not necessary and can lead to skin irritation.
