1. Which type of cell is responsible for producing antibodies in the immune system?

• A. B lymphocytes
• B. T lymphocytes
• C. Macrophages
• D. Neutrophils

Correct answer: A

Rationale: The correct answer is A: B lymphocytes. B lymphocytes (B cells) are a crucial part of the adaptive immune system. They produce antibodies, which are proteins that specifically target and neutralize pathogens such as bacteria and viruses. T lymphocytes (choice B) are involved in cell-mediated immunity rather than antibody production. Macrophages (choice C) are phagocytic cells that engulf and digest pathogens but do not produce antibodies. Neutrophils (choice D) are a type of white blood cell that primarily function in the innate immune response by phagocytosing pathogens.

2. A Native American client is admitted with a diagnosis of psychosis not otherwise specified. The client's family seems to regard the client's hallucinations as normal. What assessment can be made?

• A. The client's family regards the hallucinations from a cultural context
• B. The client will benefit from a talking circle
• C. The client will need a medicine man
• D. The client will need a single room

Correct answer: A

Rationale: Choice A is correct because the family may interpret the client's hallucinations through their cultural lens, potentially viewing them as normal or spiritually significant. Understanding and acknowledging the cultural context is essential for providing culturally sensitive care. Choices B, C, and D are incorrect because while talking circles and seeking guidance from a medicine man may be culturally relevant interventions in some contexts, the priority in this situation is to recognize and respect the family's perspective on the client's hallucinations.

3. In obtaining an orthostatic vital sign measurement, what action should the nurse take first?

• A. Count the client's radial pulse
• B. Apply a blood pressure cuff
• C. Instruct the client to lie supine
• D. Assist the client to stand upright

Correct answer: C

Rationale: The correct first action when obtaining an orthostatic vital sign measurement is to instruct the client to lie supine. This allows for establishing a baseline measurement of vital signs before any positional changes. Counting the client's radial pulse (Choice A) is a step that follows after the initial supine position to assess changes in pulse rate. Applying a blood pressure cuff (Choice B) and assisting the client to stand upright (Choice D) are actions that come later in the process after the baseline measurements are obtained in the supine position.

4. Which of the following is a primary intervention for a patient experiencing hypoglycemia?

• A. Administering insulin
• B. Providing a complex carbohydrate meal
• C. Giving 15 grams of a fast-acting carbohydrate, like glucose tablets
• D. Encouraging the patient to exercise

Correct answer: C

Rationale: Giving 15 grams of a fast-acting carbohydrate, such as glucose tablets, is the primary intervention for hypoglycemia. This rapid-acting carbohydrate helps quickly raise blood sugar levels, providing immediate relief to the patient. Administering insulin (Choice A) would further lower blood sugar levels, exacerbating the hypoglycemia. Providing a complex carbohydrate meal (Choice B) would not act quickly enough to address the immediate low blood sugar issue. Encouraging the patient to exercise (Choice D) is inappropriate during hypoglycemia as it can further deplete glucose levels.

5. A client has a prescription for a transcutaneous electrical nerve stimulator (TENS) unit for pain management during the postoperative period following a lumbar laminectomy. Which information should the nurse reinforce about the action of this adjuvant pain modality?

• A. The discharge of electricity will distract the client's focus from the pain
• B. An infusion of medication in the spinal canal will block pain perception
• C. Pain perception in the cerebral cortex is dulled by the unit's discharge of an electrical stimulus
• D. A mild electrical stimulus on the skin surface closes the gates of nerve conduction for severe pain

Correct answer: D

Rationale: The correct answer is D. TENS works by delivering a mild electrical stimulus to the skin, which can help close the 'gates' in the nervous system to block pain signals from reaching the brain, thus reducing pain perception. Choice A is incorrect because TENS does not distract from pain but rather helps manage it. Choice B is incorrect as it describes a different pain management technique involving medication in the spinal canal. Choice C is incorrect because TENS acts peripherally on nerve conduction rather than dulling pain perception in the cerebral cortex.
