Correct Answer: D

Rationale: When a patient's central venous access device (CVAD) becomes infected, administering antibiotics through the line is essential to attempt to eliminate microorganisms within the catheter. The goal is to prevent the necessity of removing the catheter, which might be required if the infection persists. Choice A, 'To prevent infiltration of the peripheral line,' is incorrect as the priority is addressing the catheter infection, not preventing issues with a peripheral line. Choice B, 'To reduce the pain and discomfort associated with antibiotic administration in a small vein,' is not relevant to the rationale for choosing the CVAD for antibiotic administration. Choice C, 'To lessen the chance of an allergic reaction to the antibiotic,' is also incorrect as the main focus is managing the catheter-associated infection rather than allergy prevention.

Correct Answer: B

Rationale: The correct answer is 'She pulls a toy behind her.' This behavior is consistent with the developmental stage of an 18-month-old who enjoys push-pull toys. Dressing oneself usually begins around 3 years old, building a tower of eight blocks at approximately 3 years old, and copying a horizontal or vertical line at about 4 years old. Choices A, C, and D are incorrect as they represent skills that are typically observed in older children.

Correct Answer: B

Rationale: The correct answer is telling the client that the medication will change the color of the urine. Rifampin can change the color of the urine and body fluid. Teaching the client about these changes is important as the client might think this is a complication. Answer A is incorrect because there is no specific requirement to take rifampin with juice. Answer C is incorrect because rifampin should be taken at consistent times, not necessarily before going to bed. Answer D is incorrect as rifampin should be taken regularly as prescribed, not based on symptoms like night sweats.

Correct Answer: C

Rationale: The correct answer is a client with diabetes mellitus, type II. Thiazide diuretics like hydrochlorothiazide can cause metabolic abnormalities, including elevated blood glucose levels. This increase is linked to diuretic-induced potassium deficiency, which reduces insulin secretion, leading to higher plasma glucose levels. Thiazides are commonly used in clients with renal impairment and hypertension. Moreover, thiazides decrease calcium excretion, reducing the risk of renal calculi, so it is not contraindicated for clients with kidney stones. Therefore, clients with diabetes mellitus, type II should avoid therapy with hydrochlorothiazide due to the potential adverse effects on blood glucose levels.

Correct Answer: D

Rationale: In cases where elderly clients deny abuse and refuse assistance, it is crucial for the nurse to respect their autonomy while also ensuring their safety. Educating the client about available services is the appropriate action as it empowers the client with information without imposing any decisions on them. It allows the client to make informed choices regarding their well-being. Reporting the incident to the authorities (Choice B) may be necessary if there is immediate danger, but in this scenario, the client denies abuse. Arranging an appointment with the client's family (Choice C) may not be appropriate without the client's consent or in cases where the family might be involved in the abuse. Simply doing nothing (Choice A) is not the best course of action as the nurse should still provide support and resources to the client.
