Exam Cram NCLEX RN Practice Questions

1. The chain of infection includes the ________________.

A. germ, agent, reservoir, exit portal, mode of transmission, entry port, and susceptible host
B. active natural, active artificial, passive natural, and passive artificial
C. opportunism, weakness, immunity, and colonization
D. intrinsic, extrinsic, internal, and external transmission

Correct answer: A

Rationale: The chain, or cycle, of infection includes the germ (microorganism), agent, reservoir, exit portal, mode of transmission, entry port, and susceptible host. This sequence describes how infections are passed from one person to another. Choice B is incorrect because it refers to types of immunity, not components of the chain of infection. Choice C is also incorrect as it lists terms unrelated to the chain of infection. Choice D is incorrect as it describes transmission types, not components of the chain of infection. Understanding the chain of infection is crucial in preventing the spread of infections by breaking one or more links in the chain, such as interrupting the mode of transmission through proper hand hygiene.

2. A client with schizophrenia seems to stop focusing during a conversation with a nurse and begins looking at the ceiling and talking to themselves. Which of the following actions should the nurse take?

A. Stop the interview at this point and resume later when the client is better able to concentrate
B. Ask the client, 'Are you seeing something on the ceiling?'
C. Tell the client, 'You seem to be looking at something on the ceiling. I see something there, too.'
D. Continue the interview without commenting on the client's behavior

Correct answer: B

Rationale: When a client with schizophrenia experiences a break in reality like staring at the ceiling and talking to themselves, the nurse should ask directly about the hallucination, as stated in choice B. By doing so, the nurse can assess the situation, identify the client's needs, and evaluate any potential risk for injury. Choices A, C, and D are incorrect. Stopping the interview (choice A) may not address the immediate concern of the hallucination. Providing false reassurance (choice C) or ignoring the behavior (choice D) does not actively address the client's altered perception of reality.

3. Which of the following conditions may cause an increased respiratory rate?

A. Stooped posture
B. Narcotic analgesics
C. Injury to the brain stem
D. Anemia

Correct answer: D

Rationale: Anemia can lead to an increased respiratory rate. In anemia, there are decreased levels of hemoglobin in red blood cells, which are responsible for carrying oxygen to the body's tissues. To compensate for the reduced oxygen-carrying capacity, the body increases the respiratory rate to bring in more oxygen. Stooped posture (Choice A) is not directly related to an increased respiratory rate. Narcotic analgesics (Choice B) are more likely to cause a decreased respiratory rate due to their central nervous system depressant effects. Injury to the brain stem (Choice C) can affect respiratory function but may not necessarily lead to an increased respiratory rate.

4. A patient diagnosed with a mild anxiety disorder has been referred to treatment in a community mental health center. Treatment most likely provided by the center includes

A. Medical management of symptoms
B. Daily psychotherapy
C. Constant staff supervision
D. Psychological stabilization

Correct answer: A

Rationale: Community mental health centers focus on rehabilitation, vocational needs, education, and socialization, as well as on the management of symptoms and medication. For a patient with a mild anxiety disorder, the primary focus would be on providing medical management of symptoms, such as prescribing appropriate medications and monitoring their effectiveness. Daily psychotherapy is not typically provided in community mental health centers for mild cases, as it may not be necessary. Constant staff supervision and psychological stabilization are more suited for patients requiring a higher level of care or in acute settings where continuous monitoring and stabilization are essential.

5. A client asks a nurse, 'Do you think I should move back home after this procedure?' and the nurse responds by saying, 'Do you think you should move back home?' What type of therapeutic communication is the nurse representing?

A. Observation
B. Reflection
C. Summarizing
D. Validating

Correct answer: B

Rationale: The nurse is demonstrating the therapeutic communication technique of reflection. In this scenario, the nurse is redirecting the question back to the client, encouraging them to explore their thoughts and feelings about the situation. Reflection involves restating a statement or question in a way that prompts the client to consider their own answers, fostering self-awareness and insight. Observation involves stating facts, summarizing involves condensing information, and validating involves confirming the client's feelings or experiences, none of which are demonstrated in this interaction.
