A patient with a myocardial infarction (MI) is being treated with intravenous morphine. What is the primary reason for administering morphine to this patient?

Correct Answer: C

Rationale: The primary reason for administering morphine to a patient with MI is to reduce cardiac workload. Morphine acts as a vasodilator and decreases preload and afterload on the heart, reducing myocardial oxygen demand. This helps to improve coronary blood flow and decrease the workload on the heart muscle, which is crucial in the setting of an MI. Explanation for other choices: A: While morphine can help reduce pain in MI, the primary reason for administering it is to reduce cardiac workload. B: Morphine may have a calming effect, but the primary goal is to reduce cardiac workload. D: Morphine can actually decrease respiratory rate as a side effect, making this choice incorrect.

Correct Answer: C

Rationale: The correct answer is C, administering prescribed opioid analgesics. This intervention is appropriate for severe abdominal pain in acute pancreatitis as opioids are effective in managing pain. Encouraging oral intake (A) can worsen symptoms, a supine position (B) can exacerbate pain, and a heating pad (D) can aggravate inflammation. Administering opioid analgesics provides direct pain relief and is the most effective intervention for alleviating severe abdominal pain in acute pancreatitis.

Correct Answer: A

Rationale: The correct answer is A. The rationale is that radioactive iodine therapy can harm a developing fetus, so patients should avoid close contact with pregnant women for one week. Choice B is incorrect as iodine supplements can interfere with the therapy. Choice C is incorrect as fluid intake should not be restricted unless specifically advised by the healthcare provider. Choice D is incorrect as there is no need to use disposable utensils for all meals.

Correct Answer: B

Rationale: The correct answer is B: Muscle weakness. Myasthenia gravis is characterized by muscle weakness due to an autoimmune attack on acetylcholine receptors at the neuromuscular junction. This leads to impaired muscle contraction and weakness, especially in the face, neck, and extremities. Joint pain (A) is not a typical symptom of myasthenia gravis. Loss of sensation (C) is more indicative of a sensory nerve disorder rather than a motor disorder like myasthenia gravis. Severe headache (D) is not a common symptom of myasthenia gravis; it is more likely to be associated with other conditions such as migraines or intracranial pathology.

Correct Answer: B

Rationale: The correct answer is B: Limit foods high in protein. Levodopa competes with amino acids for absorption in the small intestine, so consuming high-protein foods can reduce its effectiveness. Limiting protein intake can help maximize the absorption and efficacy of levodopa. Increasing vitamin C (option A) is not directly related to levodopa metabolism. Avoiding fiber (option C) is not necessary for levodopa therapy. Increasing sodium intake (option D) is not indicated for levodopa treatment in Parkinson's disease.
