Correct Answer: C

Rationale: Upon initial assessment of a client who appears anxious and upset, with claims that need further exploration, the nurse's initial response should be to gather more information about the situation. By asking 'Why is your roommate trying to kill you?' the nurse shows empathy while trying to understand the patient's perspective. This open-ended question allows the nurse to assess the situation comprehensively. Options A and D jump to conclusions or suggest actions without understanding the situation. Option B focuses solely on medication without addressing the underlying issue. It is crucial to assess the situation further before taking any action or providing treatment.

Correct Answer: C

Rationale: When the nurse is unable to distinguish the point at which the first sound was heard while taking a client's blood pressure, the best action is to deflate the cuff to zero and wait 30 to 60 seconds before reattempting the reading. Deflating the cuff for this duration allows blood flow to return to the extremity, ensuring an accurate reading on that extremity a second time. Option A of deflating the cuff completely and immediately reattempting the reading could lead to a falsely high reading. Option B, re-inflating the cuff completely and leaving it inflated for 90 to 110 seconds, reduces circulation, causes pain, and may alter the reading. Option D, documenting the exact level visualized on the sphygmomanometer where the first fluctuation was seen, is not a reliable method for assessing blood pressure and does not address the issue of obtaining an accurate reading.

Correct Answer: C

Rationale: Role-playing is the correct answer. It involves practicing appropriate behaviors during imaginary scenarios that simulate real-life situations. In this scenario, the nurse is helping the client prepare for a job interview by acting as the job supervisor. Role-playing allows the client to practice and develop strategies to cope with anxiety and panic during the actual interview. Reinforcement (Choice A) involves providing consequences to strengthen a behavior. Presenting reality (Choice B) involves helping the client differentiate between real and unreal experiences. Summarizing (Choice D) involves condensing information. In this context, role-playing is the most appropriate technique to address the client's anxiety and panic related to job interviews.

Correct Answer: B

Rationale: Nurses may work with clients who have varying cultural beliefs. Because of this, nurses must remain aware of the cultural practices associated with certain ethnic groups. Asian Americans may avoid eye contact as a sign of respect; additionally, emotional responses may be avoided except for in private situations. If this family did not have a language barrier, the nurse should continue to provide appropriate information about the surgery and recognize the cultural differences that exist. Contacting an interpreter is not necessary as there was no mention of a language barrier. Calling social services to evaluate the parent's standard of care is premature and not within the nurse's immediate scope of practice. Contacting the physician about postponing the surgery is not warranted based on the information provided.

Correct Answer: C

Rationale: To reduce the risk of venous thrombosis, the nurse should instruct the client to perform dorsiflexion and plantar flexion exercises regularly. These exercises help promote venous return and prevent venous thrombus formation. Options A, B, and D are beneficial in managing other complications of immobility, such as atelectasis and pressure ulcers, but they are less effective in preventing venous thrombosis compared to dorsiflexion and plantar flexion exercises.
