Which of the following is usually involved in Multiple myeloma?

Correct Answer: A

Rationale: Multiple myeloma is a type of cancer that develops in plasma cells, which are a type of white blood cells involved in the body's immune response. As a result, multiple myeloma primarily affects the hematologic system, which includes the blood and blood-forming tissues. This cancer typically arises in the bone marrow and can lead to an overproduction of abnormal plasma cells, which can crowd out healthy blood cells. Symptoms of multiple myeloma can include anemia, bone pain, recurrent infections, fatigue, and kidney problems, all of which are related to the hematologic system.

Correct Answer: B

Rationale: Nitrous oxide, also known as "laughing gas," is a safe and effective pharmacological option for pain management during labor. Nitrous oxide is commonly used in labor and delivery settings as it has minimal effects on the baby and allows the woman to remain in control of her pain management. It provides quick pain relief when inhaled and can be adjusted to the woman's needs during labor. Ibuprofen, morphine, and diazepam are not typically used for pain management during labor due to their potential risks and side effects, especially for the baby.

Correct Answer: D

Rationale: The presentation described is characteristic of a parathyroid adenoma. Parathyroid adenomas are benign neoplasms that can present as painless, well-defined nodules usually located in the lower pole of the thyroid gland or in close proximity, such as the lateral aspect of the neck above the clavicle. Fine-needle aspiration cytology of a parathyroid adenoma typically reveals polygonal cells with abundant granular cytoplasm, often referred to as chief cells. This is key in differentiating it from other conditions mentioned in the question.

Correct Answer: C

Rationale: The presentation described in the question, including the skin lesion resembling a "bull's eye" rash at the site of a tick bite, is characteristic of Lyme disease. Lyme disease is caused by the spirochete bacterium Borrelia burgdorferi, which is transmitted to humans through the bite of infected black-legged ticks (Ixodes scapularis). The symptoms of Lyme disease include fever, headache, myalgia, and the erythema migrans rash, which appears as a red circular rash with central clearing resembling a bull's eye.

Correct Answer: B

Rationale: Unilateral neglect is a common condition following a stroke where the individual fails to attend to one side of their body or to the space on that side. In this case, Mang Jose exhibiting signs of unilateral neglect by only shaving one side of his face, neglecting the other side. This behavior demonstrates a lack of awareness or attention to the affected side of his body, indicating a classic symptom of unilateral neglect.

Correct Answer: B

Rationale: Attending a lecture-demonstration on doing first aid is essential for the growth of a student nurse as it equips them with crucial knowledge and skills to respond effectively in emergency situations. First aid training teaches basic life-saving techniques and how to provide immediate care until medical professionals arrive. This knowledge is vital in the healthcare field, allowing the student nurse to provide immediate assistance and potentially save lives. By learning first aid procedures, the student nurse can enhance their skills, confidence, and overall capability to care for patients in various settings. This continuous learning and improvement are key to personal growth and professional development in the healthcare industry.

Correct Answer: C

Rationale: The scenario described is suggestive of a meniscus injury. A twisting injury during sports activity leading to acute knee pain and swelling, accompanied by joint effusion and tenderness along the joint line, is commonly associated with meniscus tears. The meniscus is a C-shaped cartilage structure located between the femur and tibia in the knee joint, providing cushioning and stability. The symptoms of a meniscus tear typically include pain, swelling, joint line tenderness, and sometimes mechanical symptoms like locking or clicking. Treatment may involve rest, physical therapy, or in some cases, surgery to repair or remove the torn meniscus.

Correct Answer: D

Rationale: The desired nursing action to help the pregnant patient make a decision on breastfeeding is to assist in identifying a breastfeeding goal and plan. When patients are indecisive about breastfeeding, it is essential for the nurse to support them in setting specific goals and creating a plan that aligns with their values and circumstances. This approach can help the patient feel empowered and confident in their decision-making process. Providing pamphlets and books (choice A) may be helpful, but personalized assistance in identifying a breastfeeding goal and plan is more likely to address the patient's individual needs and concerns. Providing ample time for the patient to decide (choice B) is important, but guidance and support in setting a clear goal can facilitate the decision-making process. Referring the patient to a nutritionist (choice C) may be beneficial for dietary concerns but may not directly address the decision-making process regarding breastfeeding.

Correct Answer: A

Rationale: Plasma cells are the primary type of cells responsible for the production of antibodies during the humoral immune response. When activated by antigens, B cells differentiate into plasma cells, which are specialized in producing large quantities of antibodies. These antibodies are essential in fighting off infections by binding to antigens and marking them for destruction by other immune cells. T helper cells assist in activating B cells, but the actual production of antibodies is mainly carried out by plasma cells. Memory B cells are involved in mounting a rapid and specific secondary response upon re-exposure to the same antigen. Macrophages play a role in phagocytosis and antigen presentation, but they are not the primary cells responsible for producing antibodies during the humoral immune response.
