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. After performing the appropriate client assessment, which of the following inferences would the nurse make?

A. Client is hypotensive
B. Respiratory rate of 20 breaths per minute
C. Oxygen saturation of 95%
D. Client relays anxiety about blood work

Correct answer: A

Rationale: An inference is the nurse's judgment or interpretation of cues gathered during an assessment. In this scenario, identifying a client as hypotensive would be an inference based on blood pressure readings that indicate lower than normal values. Respiratory rate and oxygen saturation levels (choices B and C) are important cues that provide additional data but do not directly point to a specific conclusion like hypotension. The client expressing anxiety about blood work (choice D) is relevant information but relates more to their emotional state rather than a physiological assessment finding.

3. The categories such as ethnicity, gender, and religion illustrate which concept?

A. Family
B. Cultures
C. Spirituality
D. Subcultures

Correct answer: D

Rationale: Within cultures, various groups of people share different beliefs, values, and attitudes due to factors such as ethnicity, religion, education, occupation, age, and gender. When these distinct groups coexist within a broader culture, they are referred to as subcultures. While ethnicity, gender, and religion are important components of individuals' identities, they do not represent the concepts of family, cultures, or spirituality. The correct answer is 'Subcultures' as these categories reflect differences within a larger cultural context, emphasizing the unique characteristics shared by members of subcultural groups.

4. A patient's nursing diagnosis is Insomnia. The desired outcome is: 'Patient will sleep for a minimum of 5 hours nightly by October 31.' On November 1, a review of the sleep data shows the patient sleeps an average of 4 hours nightly and takes a 2-hour afternoon nap. Which evaluation should be documented?

A. Consistently demonstrated
B. Often demonstrated
C. Sometimes demonstrated
D. Never demonstrated

Correct answer: D

Rationale: The correct answer is 'Never demonstrated.' Despite the patient sleeping a total of 6 hours daily, it is not achieved in one uninterrupted session at night as per the desired outcome. The patient's habit of taking a 2-hour afternoon nap also affects the evaluation. Therefore, the outcome should be evaluated as 'Never demonstrated.' Choice A, 'Consistently demonstrated,' is incorrect because the desired outcome of sleeping for a minimum of 5 hours nightly in one session is not met. Choice B, 'Often demonstrated,' is incorrect as the patient's sleep pattern does not consistently align with the desired outcome. Choice C, 'Sometimes demonstrated,' is also incorrect as the patient's sleep pattern does not meet the specific criteria set in the desired outcome.

5. A second-year nursing student has just suffered a needlestick while working with a patient that is positive for AIDS. Which of the following is the most significant action that the nursing student should take?

A. Immediately see a social worker
B. Start prophylactic AZT treatment
C. Start prophylactic Pentamidine treatment
D. Seek counseling

Correct answer: B

Rationale: Starting prophylactic AZT treatment is the most critical intervention in this scenario. Azidothymidine (AZT) is an antiretroviral medication used to prevent and treat HIV/AIDS by reducing the replication of the virus. Post-exposure prophylaxis (PEP) for HIV involves taking medication to suppress the virus and prevent infection after exposure. PEP should be initiated within 72 hours of potential HIV exposure to be effective. Seeking treatment quickly is crucial to enhance its effectiveness. Seeing a social worker (Choice A) may be helpful for emotional support but is not the immediate priority. Pentamidine treatment (Choice C) is not indicated for post-exposure prophylaxis for HIV. Seeking counseling (Choice D) is important for the nursing student's emotional well-being but does not address the urgent need for post-exposure prophylaxis to prevent HIV transmission.
