Saunders NCLEX RN Practice Questions
1. A nursing unit is implementing a new electronic charting program for the nursing staff to use. Which of the following best describes a disadvantage of using electronic charting?
- A. The information is more likely to be lost or used inappropriately.
- B. Any provider in the unit can have access to the client's medical records.
- C. The system diminishes communication between nurses and providers.
- D. The program may be confusing and difficult to implement.
Correct answer: D
Rationale: A significant disadvantage of implementing a new electronic charting program is the potential for complexity and difficulty in implementation. Introducing a new system requires time and education for staff to adapt and use it appropriately. Users may experience confusion as they learn to navigate the new charting techniques, which can impact workflow efficiency and accuracy. Option A is incorrect because electronic charting systems are designed to enhance data security and integrity, reducing the risk of information being lost or misused. Option B is incorrect as access control mechanisms can restrict who can view specific patient records. Option C is incorrect as electronic charting systems often facilitate communication between healthcare providers by providing real-time access to patient information.
2. A patient with peripheral vascular disease is receiving discharge instructions. Which of the following information should be included?
- A. Walk barefoot whenever possible.
- B. Use a heating pad to keep feet warm.
- C. Avoid crossing the legs.
- D. Use antibacterial ointment to treat skin lesions prone to infection.
Correct answer: C
Rationale: Patients with peripheral vascular disease should be advised to avoid crossing their legs as this can impede blood flow. Peripheral vascular disease, also known as arteriosclerosis obliterans, is primarily caused by atherosclerosis. Atherosclerosis results in the gradual progression of arterial occlusion due to the formation of atheromas. Crossed legs can further restrict blood flow, exacerbating the condition. Walking barefoot should be discouraged to prevent potential injuries to the feet. Using a heating pad can lead to burns and should be avoided to prevent thermal injuries. While using antibacterial ointment for skin lesions may be beneficial, it is not the priority instruction for patients with peripheral vascular disease.
3. Which of the following components is associated with hypertonic dehydration?
- A. Plasma sodium levels above 150 mEq/L
- B. Fluid moves from extracellular space to intracellular space
- C. Water loss is greater than electrolyte loss
- D. Physical signs and symptoms are grossly apparent
Correct answer: C
Rationale: The correct answer is 'Water loss is greater than electrolyte loss.' In hypertonic dehydration, there is a higher loss of water compared to electrolytes, leading to elevated concentrations of electrolytes in the body. This condition is characterized by plasma sodium levels above 150 mEq/L. As water moves from the extracellular space to the intracellular space, it results in cellular dehydration. Choice A is incorrect because the plasma sodium levels associated with hypertonic dehydration are typically above 150 mEq/L, not between 130 and 150 mEq/L. Choice B is incorrect as fluid moves from the extracellular space to the intracellular space in hypertonic dehydration. Choice D is incorrect because physical signs and symptoms may not always be grossly apparent in hypertonic dehydration.
4. While caring for a client who has just come from surgery and is in the recovery room with an endotracheal tube in place, the nurse deflates the cuff on the tube and removes it. The client sits up in bed, grasps his throat, and begins to make wheezing sounds. Which of the following conditions is the most likely cause of this situation?
- A. The client is choking on part of the tube
- B. The client has anxiety
- C. The client is having a laryngospasm
- D. The client is having a normal response from anesthesia
Correct answer: D
Rationale: After surgery, some clients may experience a laryngospasm during emergence from anesthesia. A laryngospasm can lead to the closure of the laryngeal opening due to spasm of the vocal cords. In this scenario, the client's symptoms of wheezing and throat grasping are indicative of a laryngospasm rather than choking on the tube, anxiety, or a normal response from anesthesia. The nurse should act promptly to open the airway to aid breathing and consider administering muscle relaxants as necessary.
5. A nurse is assessing a client's pulse oximetry on the surgical unit. As part of routine interventions, the nurse turns off the exam light over the client's bed. Which of the following best describes the rationale for this intervention?
- A. External light sources may cause falsely high oximetry values
- B. A bright light in the client's face may cause a low pulse oximetry
- C. External light sources may cause falsely low oximetry values
- D. The client needs a dark and quiet room to recover and maintain proper oxygenation
Correct answer: A
Rationale: When assessing a client's pulse oximetry values, the nurse should turn off any extra environmental lights that are unnecessary, including exam lights or over-bed lights. External light sources may cause falsely high oximetry values when the extra light interferes with the sensor of the oximeter, leading to inaccurate readings. Choice B is incorrect because a bright light in the client's face would not directly affect the pulse oximetry values. Choice C is incorrect as external light sources typically cause falsely high, not low, oximetry values. Choice D is incorrect as the primary reason for turning off the light is to prevent falsely high readings, not solely for the client's comfort.
