1. Which of the following white blood cells is the smallest and can be involved in humoral immunity?

Correct answer: A

Rationale: The correct answer is 'Lymphocyte.' Lymphocytes are the smallest type of white blood cells and play a crucial role in humoral immunity by producing antibodies. Monocytes are actually the largest white blood cells and are involved in phagocytosis rather than humoral immunity. Basophils are a type of granulocyte involved in allergic reactions, and erythrocytes are red blood cells responsible for oxygen transport, not part of the immune system.

2. In which of the following examples would informed consent not be required?

Correct answer: D

Rationale: In emergency situations where immediate treatment is necessary to prevent further harm or save a life, such as in option B where a child is rushed to the Emergency Room after a fall, informed consent may be waived to provide prompt care. In option A, though the patient is apprehensive about surgery and chooses not to learn the risks, informed consent is not required as it is the patient's right to refuse information. In option C, when an adult is in a coma with no next of kin listed, decisions may be made in the patient's best interest following legal and ethical guidelines. Therefore, informed consent is not needed in any of the scenarios presented.

3. A nurse is providing discharge instructions for a client who had back surgery. All of the following indicate that the client is ready for discharge EXCEPT:

Correct answer: D

Rationale: When determining if a client is ready for discharge after back surgery, it is essential to ensure that there are no signs of complications or emerging issues. A postoperative temperature of 100.8°F may indicate a developing infection, and the client should not be discharged until this is further evaluated by the physician. Choices A, B, and C are indicators that the client is progressing well and ready for discharge, as having sutures, being able to shower, and using an ice pack are typically expected postoperative activities without indicating a need for further hospitalization.

4. At a community health fair, the blood pressure of a 62-year-old client is 160/96 mmHg. The client states, "My blood pressure is usually much lower."? The nurse should tell the client to:

Correct answer: A

Rationale: The blood pressure reading of 160/96 mmHg is moderately high, indicating hypertension. Given that the client mentions their blood pressure is usually lower, there is concern for acute complications like a stroke. Therefore, an immediate reassessment of the blood pressure within the next 15 minutes is warranted to confirm the reading and take appropriate actions if necessary. Waiting for two months (Choice B) or a week (Choice D) could pose risks of delaying intervention. Seeing the healthcare provider immediately (Choice C) is a good option, but in this case, the urgency is not as high as to require immediate attention at the healthcare provider's office.

5. Mrs. G is seen for follow-up after testing for chronically high blood glucose levels. Her physician diagnoses her with type 1 diabetes. Which of the following information is part of this client's education about this condition?

Correct answer: C

Rationale: Type 1 diabetes is an autoimmune condition where the immune system attacks and destroys the beta cells in the pancreas, leading to a lack of insulin production. Insulin is essential for regulating blood glucose levels and enabling cells to use glucose for energy. Understanding that type 1 diabetes results from the destruction of beta cells helps patients comprehend the need for insulin replacement therapy. Choices A and B are incorrect as type 1 diabetes is not primarily caused by diet or exercise habits. Choice D is incorrect because type 1 diabetes is not about the body's cells rejecting insulin but rather the lack of insulin production due to beta cell destruction.
