NCLEX RN Actual Exam Test Bank

1. Where is the duodenum located in the digestive system?

A. It is the first part of the small intestine, located immediately after the stomach.
B. It is the section of the digestive system where the gall bladder delivers bile.
C. It is the section of the small intestine where the pancreas delivers digestive juices.
D. None of the above.

Correct answer: D

Rationale: The duodenum is the first part of the small intestine, located immediately after the stomach. It is where the majority of digestion takes place in the gut. The pancreas delivers digestive juices containing amylase and lipase, while the gall bladder delivers bile to aid in the digestion of fats. Choice A incorrectly states that the duodenum is the third section of the small intestine, which is inaccurate. Choice B incorrectly associates the duodenum with the gall bladder, which is not where the duodenum is located. Choice C incorrectly states that the duodenum is where the pancreas delivers digestive juices, which is partly correct but not the main function of the duodenum. Therefore, the correct answer is 'None of the above' as none of the choices accurately describe the location or functions of the duodenum.

2. When would chest thrusts be performed in an emergency situation?

A. When performing CPR to initiate cardiovascular circulation.
B. When assessing responsiveness of an unconscious patient.
C. When assisting a pregnant woman who is choking.
D. None of the above examples indicate the need for chest thrusts.

Correct answer: C

Rationale: In the scenario of an emergency where a pregnant woman is choking, chest thrusts are performed to clear the airway obstruction. This technique is used instead of abdominal thrusts to avoid potential harm to the fetus. While chest thrusts are not as effective as abdominal thrusts in clearing obstructions, they are the preferred method in this specific situation. Choices A and B are incorrect as chest thrusts are not typically performed during CPR to initiate cardiovascular circulation or when assessing responsiveness of an unconscious patient. Choice D is incorrect as chest thrusts are indeed warranted when assisting a pregnant woman who is choking.

3. A patient is having difficulty understanding how to properly run her glucose meter. Which of the following teaching methods would best help the patient understand how to use her instrument correctly?

A. Give the patient an instruction booklet and encourage her to call the office if she has questions.
B. Tell the patient to ask a healthcare provider to demonstrate how to use the instrument.
C. Have the patient watch a video demonstrating the use of the instrument.
D. Demonstrate the proper use of the instrument and then have the patient perform the process while still in the office.

Correct answer: D

Rationale: By using a demonstration and performance method of patient education, the patient is offered a chance to perform a task and have learning assessed while still in the office. This ensures that any questions that the patient has can be answered immediately, and any performance issues observed by the medical assistant can also be corrected promptly. Choice A is not as effective as providing a demonstration in person, as it may not address the patient's specific learning needs or allow for immediate feedback. Choice B suggests asking a healthcare provider to demonstrate, which is similar to the correct answer but may not always be readily available in the office. Choice C, watching a video, lacks the interactive component and immediate feedback that a live demonstration provides, making it less effective in this scenario.

4. A client is being instructed on how to use crutches. Which of the following information should be included in the teaching?

A. Place the majority of body weight on the axilla.
B. Dry crutch tips with a paper towel if they become wet.
C. Use the crutches for support to lift both feet simultaneously when ascending stairs.
D. Both B and C.

Correct answer: B

Rationale: When instructing a client on how to use crutches for ambulation, it is important to emphasize keeping the crutch tips dry to prevent slipping while bearing weight on them. Moisture on the crutch tips can lead to accidents. Therefore, the correct answer is to dry the crutch tips with a paper towel if they become wet. Choice A, placing the majority of body weight on the axilla, is incorrect as the weight should be borne through the hands, not the axilla, to avoid nerve damage. Choice C, using the crutches to lift both feet simultaneously when ascending stairs, is incorrect as the client should ascend stairs by placing weight on the unaffected leg first, followed by the crutches and then the affected leg. This method provides stability and safety during stair climbing.

5. Should standard precautions be used when providing post mortem care to a patient who has died from a massive heart attack and had no other diseases, illnesses, or infections?

A. Yes, because the patient must be treated with respect
B. Yes, you still must use standard precautions
C. No, because the patient had no infections
D. No, because this is not respectful

Correct answer: B

Rationale: Yes, you must still use standard precautions when providing post mortem care, regardless of the patient's medical history. Standard precautions are essential to prevent the transmission of potential infectious agents and protect both the healthcare provider and others from exposure. Even if the patient did not have known infections, it is crucial to maintain a safe environment and uphold professional standards of care. Choice A is incorrect as using standard precautions is primarily for infection control rather than solely for respect. Choices C and D are incorrect as the absence of infections or the notion of respect does not negate the need for standard precautions in post mortem care.
