1. According to the principle of asepsis, which situation should the PN consider to be sterile?
- A. A one-inch border around the edges of a sterile field set up in the operating room
- B. A sterile glove that the PN thinks might have touched hair
- C. A wrapped, unopened sterile 4x4 gauze pad placed on a damp table top
- D. An open sterile Foley catheter kit set up on a table at the PN's waist level
Correct answer: A
Rationale: According to the principle of asepsis, the one-inch border around the edges of a sterile field set up in the operating room is considered non-sterile, while the central area remains sterile. Therefore, the PN should consider the situation described in choice A to be sterile. Choice B is incorrect because a glove that may have touched hair is contaminated. Choice C is incorrect as a sterile item placed on a damp surface is considered contaminated. Choice D is incorrect as a sterile kit set up at the PN's waist level is prone to contamination.
2. Which of the following is NOT a second-line agent used for the treatment of Tuberculosis?
- A. Amikacin
- B. Moxifloxacin
- C. Rifabutin
- D. Cycloserine
Correct answer: C
Rationale: The correct answer is C, Rifabutin. Rifabutin is actually a first-line drug used in the treatment of tuberculosis. Choices A, B, and D (Amikacin, Moxifloxacin, and Cycloserine) are considered second-line agents for tuberculosis treatment. These drugs are used when the first-line medications are either ineffective or cannot be tolerated by the patient.
3. What is the first step in using an automated external defibrillator (AED) on a patient who has collapsed?
- A. Apply the pads to the chest
- B. Turn on the AED and follow the voice prompts
- C. Check the patient's pulse
- D. Ensure the area is clear before delivering a shock
Correct answer: B
Rationale: The correct answer is B: Turn on the AED and follow the voice prompts. This is the first step in using an AED as the device will guide you through the process of analyzing the heart rhythm and delivering a shock if necessary. Choice A, applying the pads to the chest, comes after turning on the AED. Checking the patient's pulse (Choice C) is not necessary before using an AED as the device is specifically designed to assess the need for defibrillation. Ensuring the area is clear (Choice D) is important for safety but is not the initial step in using an AED.
4. When a woman in early pregnancy is leaving the clinic, she blushes and asks the nurse if it is true that sex during pregnancy is bad for the baby. What is the best response for the nurse to give?
- A. The baby is protected by the sac. Sex is perfectly alright.
- B. It is unlikely to harm the baby. What you do with your personal life is your concern.
- C. Intercourse during pregnancy is usually alright, but you need to ask the doctor if it is acceptable for you.
- D. In a normal pregnancy, intercourse will not harm the baby. However, many women experience a change in desire. How are you feeling?
Correct answer: D
Rationale: Choice D is the best response as it reassures the patient that intercourse in a normal pregnancy will not harm the baby. It also shows empathy by acknowledging that many women experience changes in sexual desire during pregnancy. This response validates the patient's concerns and opens up a dialogue about her feelings. Choice A is incorrect as it lacks information about changes in sexual desire and oversimplifies the situation. Choice B is dismissive of the patient's concerns and does not provide adequate information. Choice C is not the best response as it suggests asking the doctor without offering immediate reassurance or addressing the patient's worries.
5. 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.
