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. The healthcare provider is examining a patient who is reporting "feeling cold."? Which is a mechanism of heat loss in the body?
- A. Exercise
- B. Radiation
- C. Metabolism
- D. Food digestion
Correct answer: B
Rationale: When the body needs to lose heat, one of the mechanisms it employs is radiation. Radiation involves the transfer of heat from the body to the environment in the form of infrared waves. While metabolism, exercise, and food digestion contribute to heat production, they are not mechanisms for heat loss. Metabolism generates heat as a byproduct, exercise increases metabolic rate leading to heat production, and food digestion involves some heat generation, but these processes do not directly facilitate heat loss. Therefore, in the scenario where the patient is feeling cold, radiation is the primary mechanism for the body to lose excess heat and maintain a stable internal temperature.
3. A registered nurse who usually works in a spinal rehabilitation unit is floated to the emergency department. Which of these clients should the charge nurse assign to this RN?
- A. A middle-aged client who says, "I took too many diet pills"? and "my heart feels like it is racing out of my chest."?
- B. A young adult who says, "I hear songs from heaven. I need money for beer. I quit drinking two (2) days ago for my family. Why are my arms and legs jerking?"?
- C. An adolescent who has been on pain medications for terminal cancer with an initial assessment finding of pinpoint pupils and a relaxed respiratory rate of 11.
- D. An elderly client who reports having taken a "large crack hit"? 10 minutes prior to walking into the emergency room.
Correct answer: C
Rationale: When assigning a floated nurse from another unit to a client in the emergency department, the goal is to choose a patient with minimal anticipated immediate complications. In this scenario, the adolescent with terminal cancer who has been on pain medications and presents with pinpoint pupils and a relaxed respiratory rate of 11 is the most stable option. These assessment findings indicate opioid toxicity, which, while serious, has the least risk of immediate complications compared to the other clients. Choice A involves a middle-aged client experiencing symptoms of possible cardiac issues due to diet pill overdose, which requires urgent intervention. Choice B presents a young adult with concerning symptoms of potential psychosis or substance withdrawal, requiring immediate attention. Choice D involves an elderly client who recently used crack, posing a high-risk situation that requires prompt evaluation and intervention. Therefore, the correct choice is the adolescent with opioid toxicity, as this client has the least immediate risk of complications among the options provided.
4. Which practice will help reduce the risk of a needlestick injury?
- A. Expose the end of the needle only when ready to enter the room for the procedure
- B. Never recap a needle after use
- C. Keep a sharps container nearby where it can be easily accessed
- D. Exchange needles from a central area rather than passing them between workers
Correct answer: C
Rationale: To reduce the risk of a needlestick injury, it is essential to keep a sharps container nearby where it can be easily accessed. This practice ensures quick and safe disposal of needles after use, minimizing the chances of accidental needlesticks. Recapping needles should be avoided as it increases the risk of injuries. Passing needles between workers should also be avoided to prevent accidental needle pricks during handovers. Therefore, the best practice to prevent needlestick injuries is to maintain a sharps container nearby for safe and immediate disposal of needles.
5. What is the most effective step in hand washing?
- A. Using friction to remove potential pathogens.
- B. Using hospital-grade soap.
- C. Moisturizing the hands after washing to prevent cracking.
- D. Washing hands with soap for at least 15 seconds.
Correct answer: A
Rationale: The most effective step in hand washing is using friction to remove potential pathogens. While using soap, moisturizing hands, and washing for a sufficient duration are important aspects of hand hygiene, the mechanical action of rubbing hands together with friction is crucial in dislodging and removing dirt, debris, and potential pathogens. Hospital-grade soap may be beneficial, but the physical act of friction is key to effective hand washing. Moisturizing after washing is important for skin health but not the most effective step in the hand washing process. Simply washing hands for a specific duration, such as 15 seconds, without proper friction may not effectively remove contaminants. Therefore, using friction for thorough cleaning is the most crucial step in hand washing.
