Correct Answer: C

Rationale: The correct answer is C: sodium and chloride. In the extracellular fluid, sodium and chloride are the major electrolytes due to their roles in maintaining fluid balance, nerve function, and muscle contraction. Potassium and phosphate (choice B) are primarily found in intracellular fluid, while potassium and chloride (choice A) are not the major electrolytes in extracellular fluid. Similarly, sodium and phosphate (choice D) are not major extracellular electrolytes. Thus, choice C is the correct answer based on the significant presence and functions of sodium and chloride in the extracellular fluid.

Correct Answer: B

Rationale: The correct answer is B because the mental health examination should be integrated into the health history interview. This allows for a comprehensive understanding of the patient's mental health status. Gathering mental health information during the health history interview is crucial as it provides insight into the patient's current mental state, past history, and potential risk factors. This integrated approach is efficient and effective in assessing the patient's mental health needs. A is incorrect because while family input can be valuable, it is not always the best or only resource for information about coping skills. C is incorrect as integrating the mental health examination into the health history interview should not necessarily take an enormous amount of extra time if done efficiently. D is incorrect as a complete mental health examination may not always be necessary to assess the patient's level of functioning; integrating mental health information into the health history interview can often provide sufficient insight.

Correct Answer: A

Rationale: The correct answer is A: Blood urea nitrogen (BUN). In CKD, the kidneys are unable to effectively filter waste products, leading to an increase in BUN levels. Elevated BUN indicates impaired kidney function. Calcium, potassium, and sodium levels may also be affected in CKD, but they are more likely to be imbalanced rather than consistently elevated. Calcium levels may be low due to impaired vitamin D activation, potassium levels may be high due to decreased excretion, and sodium levels can fluctuate based on fluid status. Therefore, while these lab values may be abnormal in CKD, BUN is the most consistently elevated marker of kidney dysfunction.

Correct Answer: A

Rationale: The correct answer is A: Administer antibiotics. Antibiotics are crucial in treating wound infections as they target and eliminate the infection-causing bacteria, preventing the infection from spreading and promoting healing. Applying a cold compress (choice B) or heat (choice C) may provide temporary relief but do not address the underlying infection. Administering IV fluids (choice D) may be necessary for hydration, but it does not directly treat the infection. Antibiotics directly target the infection, making it the most important intervention for a client with a wound infection.

Correct Answer: B

Rationale: The correct answer is B because conveying respect for differences helps build trust and encourages patients to share their perspectives openly. This fosters a positive patient-provider relationship and enhances communication. Choice A is incorrect as patients have unique behaviors. Choice C is incorrect as cultural expectations do not fully explain individual differences. Choice D is incorrect as expressing one's culture is not solely dependent on exposure to Canadian values.
