NCLEX RN Predictor Exam

1. 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.

2. A client is being admitted to the hospital because of a seizure that occurred at his home. The client has no previous history of seizures. In planning the client's nursing care, which of the following measures is most essential at the time of admission?

A. Place a padded tongue depressor at the head of the bed.
B. Pad the bed with blankets.
C. Inform the client about the importance of wearing a medical identification tag.
D. Teach the client about seizures.

Correct answer: B

Rationale: The most essential measure when admitting a client who had a seizure is to pad the bed with blankets (Option B). This is crucial to prevent injury in case of another seizure. Placing a padded tongue depressor at the head of the bed (Option A) is incorrect as current nursing guidelines advise against putting anything in the client's mouth during a seizure. Informing the client about wearing a medical identification tag (Option C) and teaching the client about seizures (Option D) are important but are more relevant once the cause of the seizure is known. It's crucial to remember that not all seizures are classified as epilepsy.

3. A patient works with a nurse to establish outcomes. The nurse believes that one outcome suggested by the patient is not in the patient's best interest. What is the nurse's best action?

A. Remain silent.
B. Educate the patient that the outcome is not realistic.
C. Explore with the patient possible consequences of the outcome.
D. Formulate an appropriate outcome without the patient's input.

Correct answer: C

Rationale: In this scenario, the nurse should collaborate with the patient rather than impose personal opinions. While the nurse should respect the patient's autonomy, they also have a duty to provide guidance. By exploring possible consequences of the suggested outcome with the patient, the nurse can facilitate a discussion that helps the patient make an informed decision. This approach respects the patient's input while ensuring their well-being. Remaining silent (Choice A) may not address the issue, educating the patient unilaterally (Choice B) may be perceived as dismissive, and formulating an outcome without patient input (Choice D) disregards the patient's autonomy and preferences.

4. While assisting a client from bed to chair, the nurse observes that the client looks pale and is beginning to perspire heavily. The nurse would then do which of the following activities as a reassessment?

A. Help client into the chair more quickly
B. Document client's vital signs taken just prior to moving the client
C. Help client back to bed immediately
D. Observe client's skin color and take another set of vital signs

Correct answer: D

Rationale: In this scenario, the nurse has observed concerning signs in the client during the transfer process. The appropriate action for reassessment would be to observe the client's skin color and take another set of vital signs. This will provide essential data to evaluate the client's condition more accurately. Options A, B, and C are interventions that do not address the need for reassessment. Moving the client more quickly, documenting previous vital signs, or returning the client to bed do not directly address the need to reassess the client's current condition.

5. 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.
