NCLEX RN Predictor Exam
1. A resident brings several electronic devices to a nursing home. One of the devices has a two-pronged plug. What rationale should the nurse provide when explaining why an electrical device must have a three-pronged plug?
- A. Controls stray electrical currents.
- B. Promotes efficient use of electricity.
- C. Shuts off the appliance if there is an electrical surge.
- D. Divides the electricity among the appliances in the room.
Correct answer: A
Rationale: A three-pronged plug functions as a ground to dissipate stray electrical currents. This helps prevent electrical shocks and ensures the safety of the user. Choice B is incorrect because the number of prongs on a plug does not impact the efficient use of electricity. Choice C is incorrect because a three-pronged plug does not shut off the appliance during an electrical surge; that role is typically fulfilled by surge protectors. Choice D is incorrect as a three-pronged plug does not divide electricity among appliances in a room; it primarily serves as a safety measure to handle excess electrical currents.
2. In addition to standard precautions, the nurse caring for a patient with rubella would plan to implement what type of precautions?
- A. Droplet precautions
- B. Airborne precautions
- C. Contact precautions
- D. Universal precautions
Correct answer: A
Rationale: Rubella is an illness transmitted by large-particle droplets, so the nurse should implement droplet precautions in addition to standard precautions. Airborne precautions are used for diseases spread through small particles in the air, such as tuberculosis, varicella, and rubeola. Contact precautions are utilized for diseases transmitted by direct contact with the patient or their environment. Universal precautions and body substance isolations are part of the CDC's standard precautions recommendations, but do not specifically address the transmission route of rubella.
3. When providing mouth care to a patient in a coma, what should you do to provide good and safe mouth care?
- A. keep the head of the bed up to prevent aspiration
- B. brush the teeth and rinse the mouth with a cup of water
- C. use a special foam swab to brush only the tongue
- D. use a special foam swab to brush the tongue and teeth
Correct answer: D
Rationale: When providing mouth care to a patient in a coma, it is crucial to use a special foam swab to brush the tongue and teeth. This method helps maintain good oral hygiene for comatose patients. Special foam swabs are designed to effectively clean all areas of the mouth, including the cheeks and tongue, ensuring thorough care. Using water for mouth care in comatose patients can lead to aspiration, so it is important to avoid this practice. Keeping the head of the bed up alone does not prevent aspiration during mouth care for comatose patients, making choice A incorrect. Merely brushing the tongue (choice C) or using a foam swab only on the tongue (choice B) may not provide the comprehensive mouth care necessary for patients in a coma.
4. While performing the physical examination, why does the nurse share information and briefly teach the patient?
- A. To help the patient feel more comfortable and gain control of the situation
- B. To build rapport and increase the patient's confidence in the examiner
- C. To assist the patient in understanding his or her disease process and treatment modalities
- D. To aid the patient in identifying questions about his or her disease and potential areas of needed education
Correct answer: B
Rationale: Sharing information and briefly teaching the patient during a physical examination helps build rapport and increase the patient's confidence in the examiner. This approach gives the patient a sense of control in a situation that can often be overwhelming. While sharing information may make the patient feel more comfortable, the primary goal is to enhance the patient's confidence in the examiner. Providing information does not necessarily directly assist the patient in understanding their disease process and treatment modalities, as this may require a more in-depth explanation. The main focus is on establishing a trusting relationship and empowering the patient during the examination, rather than solely aiding in identifying questions or areas needing education.
5. What is the flap of tissue that covers the trachea upon swallowing called?
- A. Epidermis
- B. Endocardium
- C. Epiglottis
- D. Epistaxis
Correct answer: C
Rationale: The correct answer is C: Epiglottis. The epiglottis is a flap of tissue that covers the trachea when swallowing to prevent food or liquid from entering the airway. Choice A, Epidermis, is the outer layer of the skin and is not related to the trachea. Choice B, Endocardium, is the inner lining of the heart chambers and is also unrelated to the trachea. Choice D, Epistaxis, refers to a nosebleed and is not the correct term for the tissue covering the trachea.
