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 printing out an EKG, a nurse notices that the QRS complexes are extremely small. What should be the next step?

A. Alert the physician immediately as this is a sign of impending cardiac arrest.
B. Check to see that all leads are attached and rerun the EKG.
C. Increase the sensitivity control to 20 mm deflection.
D. Decrease the run speed to 50.

Correct answer: C

Rationale: Increasing the sensitivity control to 20 mm deflection will double the sensitivity, allowing for better observation of the small QRS complexes. This step is crucial in obtaining a clearer EKG reading. Choice A is incorrect because small QRS complexes do not necessarily indicate impending cardiac arrest; it's more likely a technical issue. Choice B is not the first step to take when small QRS complexes are observed; it's important to adjust the settings first. Choice D is incorrect because decreasing the run speed to 50 is not the appropriate action for this situation; adjusting the sensitivity control is more relevant to improve the visualization of the complexes.

3. You are working the 8 am to 4 pm shift. You begin to vomit at 3 pm and you do not think that you are able to continue working. You decide to immediately go home without notifying your RN supervisor. You have ________________.

A. enough sick time, so this is not a problem.
B. finished all your work, so this is not a problem.
C. seriously abandoned the patients.
D. seriously abused and neglected the patients.

Correct answer: D

Rationale: Patient abandonment is a serious violation that can lead to disciplinary action and immediate termination of employment. It is defined as leaving patients without proper consent from the supervisor. In this scenario, leaving work without notifying the RN supervisor and potentially leaving patients unattended is considered patient abandonment, as it compromises patient safety and care. Choices A and B are incorrect because having sick time or finishing work does not justify leaving without proper protocol. Choice D is incorrect as the scenario does not indicate abuse or neglect towards the patients.

4. During an office visit, the healthcare provider is assessing a patient's skin. What part of the hand and technique would be used to best assess the patient's skin temperature?

A. Fingertips
B. Dorsal surface of the hand
C. Ulnar portion of the hand
D. Palmar surface of the hand

Correct answer: B

Rationale: The correct answer is the dorsal surface of the hand. The dorsa (backs) of the hands and fingers are best for determining temperature because the skin is thinner on the dorsal surfaces than on the palms. Fingertips are best for fine, tactile discrimination and not for assessing skin temperature. The ulnar and palmar surfaces of the hands are not as effective for assessing skin temperature as the dorsal surface because they have thicker skin layers.

5. Where is the pulse point located on the top of the foot?

A. the dorsalis pedis
B. This is the pulse point checked in patients with peripheral vascular problems.
C. This pulse point may be absent in some patients due to a congenital anomaly.
D. All of the above.

Correct answer: D

Rationale: The pulse point located on the top of the foot is known as the dorsalis pedis pulse point. It is situated on the arch of the foot, slightly lateral to the midline. This pulse point is commonly examined in patients with peripheral vascular problems to assess blood flow adequacy. Additionally, some individuals may not have this pulse point due to a congenital anomaly. Therefore, all the given statements are correct in relation to the dorsalis pedis pulse point, making 'All of the above' the correct answer. Choices A, B, and C are all individually valid characteristics of the dorsalis pedis pulse point, hence selecting 'All of the above' as the correct answer is appropriate.
