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. The nurse is preparing to perform a physical assessment. The correct action by the nurse is reflected by which statement?

A. Performs the examination from both sides of the bed.
B. Examines tender or painful areas last to help relieve the patient's anxiety.
C. Follows a flexible examination sequence, considering the patient's age and condition.
D. Organizes the assessment to ensure that the patient does not change positions too often.

Correct answer: D

Rationale: The nurse should organize the assessment to minimize the patient's need to change positions frequently, ensuring efficiency and comfort. It is essential to perform the examination from both sides of the bed to facilitate a comprehensive assessment. Examining tender or painful areas last can help reduce patient discomfort and anxiety. The examination sequence should be flexible, taking into account the patient's age, condition, and specific needs. This approach allows for a tailored and patient-centered assessment, optimizing the quality of care provided.

3. What technique would the nurse use to accurately assess a rectal temperature in an adult?

A. Use a lubricated blunt tip thermometer.
B. Insert the thermometer 2 to 3 inches into the rectum.
C. Leave the thermometer in place for up to 8 minutes if the patient is febrile.
D. Wait 2 to 3 minutes if the patient has recently smoked a cigarette.

Correct answer: A

Rationale: To accurately assess a rectal temperature in an adult, a nurse should use a lubricated rectal thermometer with a short, blunt tip. The thermometer is inserted only 2 to 3 cm (1 inch) into the rectum and left in place for 2 minutes. Choice B is incorrect as inserting the thermometer 2 to 3 inches would be too deep and inaccurate. Choice C is incorrect as leaving the thermometer in place for up to 8 minutes is unnecessary and can cause discomfort. Choice D is incorrect as smoking a cigarette does not impact rectal temperatures.

4. A 30-year-old woman has recently moved to the United States with her husband. They are living with the woman's sister until they can get a home of their own. When company arrives to visit the woman's sister, the woman feels suddenly shy and retreats to the back bedroom to hide until the company leaves. She explains that her reaction to guests is simply because she does not know how to speak "perfect English."? What is this woman likely experiencing?

A. Culture shock
B. Cultural taboos
C. Cultural unfamiliarity
D. Culture disorientation

Correct answer: A

Rationale: The woman in the scenario is likely experiencing culture shock. Culture shock is a term used to describe the state of disorientation or inability to respond to the behavior of a different cultural group due to sudden strangeness, unfamiliarity, and incompatibility with the individual's perceptions and expectations. In this case, the woman's feelings of shyness and retreating due to not feeling confident in speaking 'perfect English' align with symptoms of culture shock. The other choices are incorrect: Cultural taboos refer to behaviors or actions that are prohibited within a particular culture; cultural unfamiliarity suggests a lack of knowledge about a specific culture, which is not the case here; and culture disorientation is not a commonly used term in cultural psychology, making it an incorrect option.

5. When performing an EKG, the patient starts to laugh out of feelings of anxiety. What would you expect the EKG to show? (Choose the BEST answer.)

A. Increased pulse rate, normal EKG
B. Decreased pulse rate, abnormal EKG
C. Tachycardia, poor EKG graph
D. Bradycardia, poor EKG graph

Correct answer: C

Rationale: When a patient laughs due to anxiety during an EKG, it is likely to cause tachycardia, which is a rapid heart rate. This increased heart rate can lead to poor EKG graph quality as the electrical signals from large moving muscles can interfere with data collection from the chest leads. Therefore, in this scenario, the EKG is expected to show tachycardia with poor graph quality. Choices A, B, and D are incorrect because a patient laughing out of anxiety is more likely to result in an increased pulse rate (tachycardia) rather than a decreased pulse rate (bradycardia) or a normal EKG.
