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. After performing the appropriate client assessment, which of the following inferences would the nurse make?
- A. Client is hypotensive
- B. Respiratory rate of 20 breaths per minute
- C. Oxygen saturation of 95%
- D. Client relays anxiety about blood work
Correct answer: A
Rationale: An inference is the nurse's judgment or interpretation of cues gathered during an assessment. In this scenario, identifying a client as hypotensive would be an inference based on blood pressure readings that indicate lower than normal values. Respiratory rate and oxygen saturation levels (choices B and C) are important cues that provide additional data but do not directly point to a specific conclusion like hypotension. The client expressing anxiety about blood work (choice D) is relevant information but relates more to their emotional state rather than a physiological assessment finding.
3. A client with an enlarged prostate is having trouble starting his flow of urine when using the bathroom. Another name for this condition is:
- A. Hesitancy
- B. Oliguria
- C. Retention
- D. Urgency
Correct answer: A
Rationale: Urinary hesitancy occurs when a client has difficulty starting a flow of urine while using the bathroom. Hesitancy may be due to physiological factors, such as obstruction from an enlarged prostate, or due to psychological factors, such as anxiety or embarrassment. Oliguria refers to decreased urine output, retention is the inability to empty the bladder fully, and urgency is the sudden and strong need to urinate.
4. 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.
5. You are working the 4 pm to 12 midnight evening shift. You are taking care of a group of patients. The supervising RN identifies 5 patients who get a medication at 'HS'. When will you give this medication?
- A. After the dinner meal
- B. Whenever requested
- C. At the patient's bedtime
- D. Before the end of the shift
Correct answer: C
Rationale: The correct answer is to give the medication at the patient's bedtime. 'HS' is a medical abbreviation that stands for 'hora somni,' which translates to 'at bedtime' or 'at the hours of sleep.' This timing ensures that the medication is administered appropriately to align with the patient's sleep schedule and maximize its effectiveness. Choices A, B, and D are incorrect because giving the medication after dinner, whenever requested, or before the end of the shift may not coincide with the intended purpose of the medication, potentially affecting its efficacy and patient outcomes.
