NCLEX RN Exam Prep
1. Your elderly patient has a temperature of 98.5 degrees. Is there anything else that a nurse should do, in addition to documenting this temperature?
- A. No, this temperature is within normal limits.
- B. No, this temperature is normally hyperthermic.
- C. Yes, this temperature is highly hyperthermic.
- D. Yes, this temperature is highly hypothermic.
Correct answer: A
Rationale: No, there is nothing else that a nurse should do. A temperature of 98.5 degrees for an elderly patient falls within normal limits. Other choices are incorrect because the temperature is not hyperthermic (abnormally high) or hypothermic (abnormally low), making choices B, C, and D inaccurate responses in this scenario.
2. Which of the following actions can help prevent a fire in the area where a healthcare professional works?
- A. Using an adaptor when plugging in client equipment
- B. Marking equipment that is not working properly and using it carefully until it can be inspected by maintenance
- C. Notifying visitors or posting signs that indicate oxygen is in use in certain areas
- D. Keeping extra equipment stored in one area with other supplies and materials
Correct answer: C
Rationale: The correct action to help prevent a fire in a healthcare setting is to notify visitors or post signs indicating that oxygen is in use in certain areas. Oxygen is a combustible material, and awareness of its presence is crucial to prevent fire hazards. By informing all individuals in the facility about the use of oxygen through clear signs or notifications, the risk of improper use and potential fire accidents can be minimized. Choice A is incorrect because using an adaptor when plugging in client equipment is not directly related to fire prevention. Choice B is also incorrect as marking faulty equipment and using it until inspection does not directly address fire prevention. Choice D is not a recommended action for fire prevention; storing extra equipment with supplies does not address the specific fire risk associated with oxygen use.
3. What is the first aid for frostbite?
- A. Running cold water over the affected area. Warm or hot water will shock the area and cause more tissue damage.
- B. Run warm water over the area to rapidly rewarm the affected area.
- C. Run hot water over the area to warm the area as quickly as possible.
- D. Cover the area with a blanket, using a heating pad if the blanket isn't warm enough.
Correct answer: A
Rationale: First aid for frostbite involves running cold water over the affected area. It is important to avoid warm or hot water as it can shock the area and cause further tissue damage. Warm water should not be used to rapidly rewarm the affected area. Similarly, hot water should also be avoided as it can warm the area too quickly and potentially cause harm. Covering the area with a blanket and using a heating pad may not be effective and can even lead to more damage. Seeking medical assistance is crucial if the tissue appears necrotic to prevent further complications.
4. What does preload refer to?
- A. The volume of blood entering the left side of the heart
- B. The volume of blood entering the right side of the heart
- C. The pressure in the venous system that the heart must overcome to pump the blood
- D. The pressure in the arterial system that the heart must overcome to pump the blood
Correct answer: B
Rationale: Preload refers to the volume of blood that enters the right side of the heart. This volume stretches the fibers in the heart before contraction. Preload is an essential factor in determining the force of ventricular contraction. Choices A, C, and D are incorrect. Choice A is incorrect because preload is specifically related to the volume of blood entering the right side of the heart. Choices C and D are incorrect as they refer to afterload, which is the pressure that the heart must overcome to pump blood out of the ventricles into the systemic or pulmonary circulation.
5. To properly read a meniscus,
- A. hold the measuring device at eye level and read the bottom of the curve of the liquid level
- B. hold the measuring device at eye level and read the top of the curve of the liquid level where the liquid adheres to the walls of the container.
- C. hold the measuring device at table level and, looking down into the measuring device, read the bottom of the curve of the liquid level.
- D. hold the measuring device at table level and, looking down into the measuring device, read the top of the curve of the liquid level.
Correct answer: A
Rationale: To properly read a meniscus, it is essential to hold the measuring device at eye level to avoid parallax error. Reading the bottom of the curve of the liquid level is correct because the meniscus is the concave or convex curve at the liquid's surface. Choice B is incorrect because reading the top of the curve where the liquid adheres to the walls of the container can lead to inaccurate measurements. Choices C and D are incorrect as they suggest holding the device at table level, which can introduce parallax error and result in an incorrect reading.
