Correct Answer: C

Rationale: The correct answer is C: A decreased number of functioning acetyl-choline receptor sites. This is because in diseases like myasthenia gravis, there is an autoimmune attack on acetylcholine receptor sites, leading to decreased functionality. Choice A is incorrect because it refers to a genetic defect in acetylcholine production, which is not typically the cause of myasthenia gravis. Choice B is incorrect as it suggests a reduced amount of acetylcholine, which is not the primary issue in myasthenia gravis. Choice D is incorrect as it mentions inhibition of the enzyme Ache, which is not the main mechanism in this disease.

Correct Answer: B

Rationale: The correct answer is B because using a PICOT question involves formulating a research question to guide evidence-based practice. B indicates the nurse is implementing interventions based on scientific research, aligning with the PICOT framework (Patient, Intervention, Comparison, Outcome, Timeframe). This approach ensures that care decisions are supported by the best available evidence, leading to improved patient outcomes. Choice A is incorrect because practicing nursing based on court evidence does not align with the PICOT framework. Choice C is incorrect as using standardized care plans for all patients may not consider individual patient needs and preferences as required in a PICOT question. Choice D is incorrect as planning care based on tradition does not involve integrating current research evidence as in the PICOT approach.

Correct Answer: A

Rationale: The correct answer is A: Liver. The liver is a common site for metastasis because it receives blood from various organs, making it a prime location for cancer cells to travel and establish secondary tumors. Additionally, the liver has a rich blood supply and provides a favorable environment for cancer cells to thrive. In contrast, B (Reproductive tract) and C (Colon) are not as common sites for metastasis compared to the liver. Choice D (White blood cells) is incorrect as metastasis involves the spread of cancer cells to distant organs, not within the blood cells themselves.

Correct Answer: A

Rationale: The correct answer is A: Increase fluid intake. This is important for a client undergoing radiation and chemotherapy for non-Hodgkin's lymphoma to prevent dehydration, help flush out toxins, and support kidney function. Increasing fluid intake can also help manage side effects like nausea and vomiting. Choices B, C, and D are incorrect because low-fat meals, soft bland foods, and foods rich in folic acid are not specifically indicated for clients undergoing radiation and chemotherapy for non-Hodgkin's lymphoma.

Correct Answer: B

Rationale: The correct answer is B: Fluid retention and weight gain. Prednisone is a corticosteroid that can cause fluid retention and weight gain as common adverse reactions. Here's the rationale: Prednisone is known to increase sodium and water retention in the body, leading to fluid retention and subsequent weight gain. This occurs due to the drug's impact on the body's electrolyte balance. Tetany and tremors (Choice A) are not common adverse reactions associated with prednisone use. Anorexia and weight loss (Choice C) are also not typical reactions, as prednisone is more likely to cause weight gain. Choice D, "None of the above," is incorrect as prednisone commonly causes fluid retention and weight gain as adverse reactions.
