Safe and Effective Care Environment NCLEX RN Questions

1. The NFPA diamond has four colors. The blue diamond:

A. indicates hazards to health.
B. designates that it is safe to use water to put out this type of fire.
C. indicates that ice is necessary to treat an injury with this type of chemical.
D. indicates that the chemical may be incinerated upon disposal.

Correct answer: A

Rationale: The National Fire Protection Agency (NFPA) uses a safety diamond to communicate the level of threat posed by a specific chemical. The blue diamond in the NFPA diamond system signifies potential health hazards associated with the use of that chemical. Choice B is incorrect because the blue diamond does not indicate anything about using water to extinguish fires. Choice C is incorrect as the NFPA diamond does not provide information on treating injuries. Choice D is also incorrect as the blue diamond does not suggest incineration upon disposal; it pertains to health hazards.

2. When educating a client about their new prescription for warfarin, what should the nurse advise?

A. To have his white blood cell count tested once a month
B. To avoid any activities that could lead to injury
C. To avoid eating leafy green vegetables
D. Both A and B

Correct answer: B

Rationale: The correct answer is to advise the client to avoid any activities that could lead to injury when taking warfarin. Warfarin is an anticoagulant medication that decreases blood clotting, increasing the risk of bleeding. Engaging in activities that may result in injury can lead to uncontrolled bleeding, which can be serious. While monitoring white blood cell count is not specifically related to warfarin therapy, avoiding leafy green vegetables is important due to their vitamin K content, which can interfere with warfarin's effectiveness. Therefore, the client should be educated to avoid activities that could cause injury to prevent potential bleeding complications.

3. Which of the following is part of client teaching regarding antiembolism stockings?

A. Instruct the client to roll the top portion of the stocking down if it is too long
B. Stockings are applied with the toes uncovered at the end
C. Measure for thigh-high stockings from the foot to the knee
D. Stockings are to be smooth from end to end without wrinkles

Correct answer: D

Rationale: When educating clients about antiembolism stockings, it is essential to emphasize that the stockings should be smooth from end to end without wrinkles. Wrinkles in the stockings can impede circulation, defeating the purpose of wearing them to prevent blood clot formation. Instructing the client to roll the top portion of the stocking down if it is too long (Choice A) is incorrect as it can create unnecessary pressure points. Stockings should be applied with the toes covered at the end (Choice B) to ensure proper compression. Measuring for thigh-high stockings should be done from the knee to the foot (Choice C) to ensure the correct fit and compression gradient.

4. When assessing a pulse, what should be noted?

A. Rate
B. Rate and quality
C. Rate, quality, and fullness
D. Rate, quality, fullness, and regularity

Correct answer: C

Rationale: When assessing a pulse, it is important to note the rate (number of beats per minute), quality (regular or irregular), and fullness (thread and weak or full and bounding). These aspects provide crucial information about the patient's cardiovascular status. Regularity, as mentioned in option D, is not typically assessed during a pulse check and is not necessary for routine pulse assessment. Choice A is too limited as it overlooks important aspects beyond just the rate. Choice B improves by adding quality but still lacks the fullness aspect. Choice C is the most comprehensive and accurate as it includes all three essential aspects for a thorough pulse assessment.

5. Which acronym would BEST describe the procedure for assessing a patient that appears unconscious?

A. WBC
B. QRS
C. XYZ
D. ABC

Correct answer: D

Rationale: The correct answer is D, 'ABC.' The ABC method stands for Airway, Breathing, Circulation. When encountering an unconscious patient, it is crucial to first ensure their Airway is clear by performing the 'head tilt, chin lift' maneuver. Next, assess Breathing by observing for chest rise and fall, listening for breath sounds, and feeling for airflow. Finally, check for Circulation by assessing for a pulse. Choices A, B, and C ('WBC,' 'QRS,' 'XYZ') are incorrect as they do not represent the standard approach to assessing an unconscious patient.
