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 teaching a patient to use the three-point gait technique of crutch use:

A. The injured leg moves ahead at the same time as both crutches.
B. One crutch moves at a time and is then followed by the injured leg.
C. Both crutches move ahead at the same time followed by both legs at the same time.
D. None of the above are correct.

Correct answer: A

Rationale: The correct technique for a three-point gait involves the injured leg moving simultaneously with both crutches, followed by the uninjured leg. This gait pattern is utilized when the patient is unable to bear full weight on one of their legs. Choice A accurately describes the appropriate sequence of movements for the three-point gait technique. Choices B and C do not accurately reflect the correct pattern of movement during the three-point gait technique, making them incorrect. Choice D is incorrect as there is a correct option among the choices provided.

3. The nurse supervises unlicensed assistive personnel (UAP) who are providing care for a patient with right lower lobe pneumonia. The nurse should intervene if which action by UAP is observed?

A. UAP splint the patient's chest during coughing.
B. UAP assist the patient to ambulate to the bathroom.
C. UAP help the patient to a bedside chair for meals.
D. UAP lower the head of the patient's bed to 15 degrees.

Correct answer: D

Rationale: The correct action for the nurse to intervene in is when the UAP lowers the head of the patient's bed to 15 degrees. This position can decrease ventilation in a patient with pneumonia, potentially worsening their condition. Choices B and C involve assisting the patient with activities of daily living and promoting mobility, which are appropriate for the patient's care. Choice A, splinting the patient's chest during coughing, can help the patient manage coughing effectively, which is also appropriate for a patient with pneumonia.

4. A client is being assisted with ambulation in the hallway using a gait belt when they become dizzy and start to faint. What is the first action the nurse should take?

A. Stand behind the client and prepare to catch them if they fall
B. Assist the client to sit in the nearest chair or slide down along a wall
C. Grasp the client under the arms and pull them upward
D. Call for help from nearby staff

Correct answer: A

Rationale: If a client becomes dizzy and starts to faint while being assisted with ambulation, the nurse's first action should be to assist the client into a sitting position to prevent or reduce the impact of a fall. This can be done by guiding the client to sit in the nearest chair or sliding down along a wall for support. Option A is incorrect because standing behind the client may not prevent a fall and could potentially lead to injury. Option C is incorrect as pulling the client upward may worsen the situation. Option D, calling for help, is not the first action to take when the client is at risk of falling.

5. When providing mouth care to a patient in a coma, what should you do to provide good and safe mouth care?

A. keep the head of the bed up to prevent aspiration
B. brush the teeth and rinse the mouth with a cup of water
C. use a special foam swab to brush only the tongue
D. use a special foam swab to brush the tongue and teeth

Correct answer: D

Rationale: When providing mouth care to a patient in a coma, it is crucial to use a special foam swab to brush the tongue and teeth. This method helps maintain good oral hygiene for comatose patients. Special foam swabs are designed to effectively clean all areas of the mouth, including the cheeks and tongue, ensuring thorough care. Using water for mouth care in comatose patients can lead to aspiration, so it is important to avoid this practice. Keeping the head of the bed up alone does not prevent aspiration during mouth care for comatose patients, making choice A incorrect. Merely brushing the tongue (choice C) or using a foam swab only on the tongue (choice B) may not provide the comprehensive mouth care necessary for patients in a coma.
