A client asks nurse Carlos the rationale for giving multi-drug treatment for tuberculosis. Which is an appropriate response?

Correct Answer: D

Rationale: The correct answer is D because using multiple drugs for tuberculosis reduces the development of resistant strains of the bacteria. When multiple drugs are used simultaneously, it decreases the likelihood of the bacteria developing resistance to any single drug. This approach helps to ensure that the treatment remains effective over time. Explanation for other choices: A: While using multiple drugs may allow for reduced dosages, the primary rationale is not solely to administer lower levels of drugs. B: Although using multiple drugs may help in managing side effects, the primary rationale is to prevent the development of resistant strains. C: While multiple drugs may have a synergistic effect, the main purpose is to prevent resistance rather than potentiate the action of individual drugs.

Correct Answer: B

Rationale: The correct answer is B: soften the fecal mass and lubricate the walls of the rectum and colon. First, the oil retention enema helps soften the fecal mass, making it easier to pass. Second, the oil lubricates the walls of the rectum and colon, reducing friction and making the passage of stool smoother. This helps prepare the fecal impaction for removal during the subsequent cleansing enema. Choices A, C, and D are incorrect because they do not directly address the primary goal of softening the fecal mass and lubricating the walls of the intestines to facilitate the removal of the impaction.

Correct Answer: C

Rationale: Step-by-step rationale for choice C (Serum potassium level of 5.8 mEq/L) being the best to support a diagnosis of Addison's disease: 1. Addison's disease is characterized by adrenal insufficiency, leading to decreased aldosterone secretion. 2. Decreased aldosterone causes hyperkalemia due to impaired potassium excretion. 3. Elevated serum potassium levels above the normal range (3.5-5.0 mEq/L) are a classic finding in Addison's disease. 4. Therefore, a serum potassium level of 5.8 mEq/L strongly supports the diagnosis of Addison's disease. Summary: - Choice A (BUN level): BUN is not specific to Addison's disease and does not directly relate to adrenal function. - Choice B (Serum sodium level): Hyponatremia is a common finding in Addison's disease, but it is not as specific as hyperkalemia. - Choice D (Blood glucose level): Blood glucose

Correct Answer: B

Rationale: The correct answer is B: Increased urine osmolarity. In hyperglycemia, the body tries to eliminate excess glucose through increased urine output, causing a concentrated urine with high osmolarity. This indicates fluid deficit. Cool, clammy skin (A) may suggest poor perfusion but not fluid volume deficit. Distended neck veins (C) are more indicative of fluid overload. Serum sodium level (D) may be elevated in fluid deficit but does not directly assess volume status like urine osmolarity does.

Correct Answer: D

Rationale: The correct answer is D because crying whenever diabetes is mentioned indicates emotional distress, a key component of ineffective coping. This response suggests the client is overwhelmed by the diagnosis, affecting their ability to cope effectively. In contrast, choices A, B, and C focus more on physical aspects and management of diabetes, not coping mechanisms. Weight gain could be related to poor diet or medication side effects, skipping insulin doses might indicate non-adherence, and failure to monitor blood glucose could be due to lack of knowledge or resources. Overall, D is the best choice as it directly relates to the client's emotional response to the diagnosis.
