Correct Answer: A

Rationale: The correct answer is A: Myasthenia gravis. In myasthenia gravis, there is a decrease in acetylcholine receptors at the neuromuscular junction, leading to muscle weakness and fatigue. This occurs due to autoimmune destruction of these receptors. ALS (B) affects motor neurons, not acetylcholine receptors. Guillain-Barre syndrome (C) is an autoimmune disorder affecting peripheral nerves, not neuromuscular junctions. Muscular dystrophy (D) is a genetic disorder causing muscle degeneration, not affecting acetylcholine receptors.

Correct Answer: D

Rationale: The correct answer is D because referring the patient to a pain management specialist for evaluation is essential in this scenario. The specialist can conduct a comprehensive assessment to identify the underlying causes of the intractable pain and recommend a tailored pain management plan. This approach ensures a multidisciplinary approach to address the complex nature of the patient's pain. Choice A is incorrect because simply increasing the dosage of the current opioid medication may not effectively address the underlying cause of the pain and can lead to potential side effects or opioid tolerance. Choice B is incorrect as switching to a different opioid medication without a thorough evaluation may not guarantee better pain control and can increase the risk of adverse effects or inadequate pain relief. Choice C is incorrect as administering adjuvant analgesic medications without addressing the root cause of the pain may not provide adequate pain relief and does not address the need for a specialized pain management plan.

Correct Answer: C

Rationale: The correct answer is C because encouraging the patient to ask questions and express concerns promotes patient empowerment and active participation in self-care. This approach fosters communication, understanding, and collaboration between the nurse and patient, leading to better medication adherence. Choice A is incorrect as it lacks patient involvement. Choice B is helpful but does not necessarily empower the patient. Choice D is directive and does not encourage active participation or empowerment.

Correct Answer: B

Rationale: The correct answer is B: IgA. In multiple myeloma, there is a proliferation of abnormal plasma cells, leading to a decrease in normal antibody production. IgA is the most abundant immunoglobulin in mucosal secretions and plays a crucial role in mucosal immunity. Therefore, a deficiency in IgA is common in patients with multiple myeloma. IgG is the most abundant immunoglobulin in the blood and is typically less affected in multiple myeloma. IgM is the first antibody produced in response to an infection and is less likely to be deficient in this case. IgE is primarily involved in allergic responses and is not typically affected in multiple myeloma.

Correct Answer: A

Rationale: The correct answer is A: Scabies. This presentation is classic for scabies infestation caused by the Sarcoptes scabiei mite. The intensely pruritic linear burrows are pathognomonic. Close contact with an individual with scabies increases the likelihood of transmission. The other choices, B: Pediculosis, C: Tinea corporis, and D: Contact dermatitis, do not typically present with linear burrows on the hands and wrists. Pediculosis presents with lice infestation, Tinea corporis with circular lesions, and contact dermatitis with erythema and edema.
