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: B

Rationale: The correct answer is B, anaphylactic shock and angioedema, as it is the most severe complication of allergies and can be life-threatening. Anaphylactic shock can lead to airway constriction, severe drop in blood pressure, and organ failure. Angioedema can cause swelling of the face, lips, and throat, leading to difficulty breathing. Bronchitis (A) is a respiratory condition that can occur due to allergies but is not typically life-threatening. Cardiac arrest (C) is a serious complication but not directly related to allergies. Asthma and nasal polyps (D) are common allergic conditions but are not as immediately life-threatening as anaphylactic shock.

Correct Answer: C

Rationale: The correct answer is C: bacteria. Hepatitis is primarily caused by viruses (such as Hepatitis A, B, C), toxins (like alcohol or certain medications), and chemicals/drugs. Bacteria do not typically cause hepatitis as it is a viral infection that affects the liver. Therefore, choice C is the exception among the listed causes. Viruses directly target liver cells, toxins can damage the liver, and certain chemicals/drugs can lead to liver inflammation. Hence, bacteria do not play a significant role in causing hepatitis.

Correct Answer: C

Rationale: The correct answer is C: Take piroxicam with food or oral antacid. This instruction helps to reduce GI irritation by providing a protective barrier for the stomach lining. Piroxicam is known to cause GI upset due to its effect on prostaglandin synthesis. Taking it with food or an antacid can help minimize this side effect. Choice A (Space the administration every 4 hours) does not address the issue of GI irritation and is not a recommended strategy for preventing this side effect. Choice B (Use the drug for a short time only) is not a direct intervention to prevent GI upset and does not provide guidance on how to manage the side effect when taking the medication. Choice D (Decrease the piroxicam dosage) may not be necessary if the client can manage the side effects with the simple intervention of taking it with food or an antacid.

Correct Answer: C

Rationale: Correct Answer: C - Encourage fluid intake of 3000ml/day Rationale: Encouraging fluid intake of 3000ml/day helps to flush out bacteria from the urinary tract, reducing the risk of infection spread. Adequate hydration also prevents further stone formation. Incorrect Choices: A: Administering IV fluids and blood transfusions may not directly address the urinary tract infection. B: Administering narcotic analgesics may mask symptoms but not treat the root cause of the infection. D: Suggesting herbs or spices does not address the need for adequate fluid intake to manage the urinary tract infection.
