Correct Answer: C

Rationale: The correct answer is C: "You may feel a burning sensation when the dye is injected." This is important to include in preprocedure teaching for carotid angiography because it prepares the patient for a common sensation they may experience during the procedure. Providing this information helps manage expectations and reduce anxiety. Choice A is incorrect because carotid angiography is typically done with the patient awake. Choice B is incorrect as carotid angiography usually takes around 30-60 minutes. Choice D is incorrect because there can be complications associated with carotid angiography, such as allergic reactions or damage to blood vessels.

Correct Answer: D

Rationale: Step 1: Multiple sclerosis (MS) is a progressive disease affecting the central nervous system. Step 2: Axon degeneration occurs in MS, leading to impaired nerve signal transmission. Step 3: MS is characterized by sclerosed patches, or plaques, in the nervous system. Step 4: Demyelination of the brain and spinal cord is a hallmark feature of MS. Step 5: Therefore, all of the above choices are correct as they accurately describe key features of MS.

Correct Answer: C

Rationale: The hallmark of nephritic syndrome is edema due to proteinuria leading to hypoalbuminemia. Protein loss in urine causes decreased colloid osmotic pressure, leading to fluid leaking into tissues, causing edema. Osmotic diuresis (A) is unrelated to nephritic syndrome. Hypolipidemia (B) and hyperproteinemia (D) are not characteristic of nephritic syndrome.

Correct Answer: C

Rationale: The correct answer is C: Health promotion. In this scenario, the nurse identified the patient's desire to enhance urinary elimination abilities through self-catheterization, indicating a readiness for positive change. Health promotion diagnoses focus on improving well-being and enhancing quality of life. This diagnosis supports the patient's proactive approach to managing their condition. Incorrect choices: A: Risk - This diagnosis would be used if the patient was at risk for complications related to urinary elimination, not actively seeking to improve it. B: Problem focused - This type of diagnosis would be used if the patient was experiencing issues with urinary elimination that needed to be addressed. D: Collaborative problem - This diagnosis would involve identifying a problem that requires collaboration between healthcare professionals to resolve, which is not the case in this scenario.

Correct Answer: D

Rationale: Step 1: Levothyroxine (Synthroid) is the synthetic form of the thyroid hormone T4, the main hormone produced by the thyroid gland. Step 2: Levothyroxine is the preferred agent for thyroid hormone replacement therapy in hypothyroidism due to its stable and consistent potency. Step 3: Levothyroxine is well-absorbed by the body and has a long half-life, allowing for once-daily dosing. Step 4: Other choices are incorrect because Methimazole is used to treat hyperthyroidism, Livothyronine is a form of T3 hormone not commonly used for replacement therapy, and Thyroid USP dessicated is derived from animal thyroid glands and has inconsistent hormone content. Summary: Levothyroxine (Synthroid) is the preferred choice for thyroid hormone replacement therapy due to its synthetic nature, stable potency, good absorption, and long half-life.
