Correct Answer: B

Rationale: The most significant factor in planning dietary changes for a client with cardiovascular disease is the involvement of the client in planning the change. By involving the client in the planning process, the nurse ensures that the client takes ownership of their health and is more likely to adhere to and succeed in modifying dietary habits. This empowerment and engagement enhance the client's motivation and commitment to making sustainable changes. Financial resources, availability of low-sodium foods, and frequency of dietary counseling sessions are important considerations but are not as crucial as the client's active involvement in the planning process.

Correct Answer: B

Rationale: The correct answer is B, Hypoglycemia. In diabetes mellitus, hypoglycemia can lead to symptoms such as anxiety, shakiness, and weakness due to low blood sugar levels. Hyperglycemia (choice A) is high blood sugar levels and typically presents with symptoms like increased thirst and frequent urination. Ketoacidosis (choice C) is a serious complication of diabetes characterized by high levels of ketones in the blood, leading to symptoms such as fruity breath and rapid breathing. The Dawn phenomenon (choice D) refers to an abnormal early-morning increase in blood sugar levels without an associated hypoglycemia during the night.

Correct Answer: D

Rationale: Choosing option D, 'Try to help your dad enjoy this time as much as he can,' is the most appropriate response by the nurse. This response shows empathy and compassion towards the client and their family during this difficult transition. The focus on supporting the client in enjoying their remaining time reflects a holistic approach to care. Options A, B, and C are not the best responses in this situation. Option A could lead to unnecessary details that might be overwhelming for the family. Option B shifts the responsibility to the social worker without providing immediate support. Option C deflects the son's concerns to another healthcare professional when emotional support is needed.

Correct Answer: A

Rationale: Offering relaxation techniques addresses the client's immediate concern by providing a proactive approach to managing anxiety. It shows empathy and offers a practical solution. Requesting a social worker for meditation (Choice B) may not be the most direct response to the client's immediate worry. Attempting biofeedback (Choice C) may not be suitable without the client's interest or consent. Telling the client to think of something else (Choice D) dismisses the client's feelings and does not provide constructive support.

Correct Answer: A

Rationale: The correct answer is to Evacuate the client (Choice A). In the event of a fire, the safety of the client is the top priority. The RACE (Rescue, Alarm, Contain, Extinguish) mnemonic is used in fire emergencies. The first step is to Rescue or Evacuate the individual from immediate danger. Attempting to extinguish the fire (Choice B) may endanger both the client and the nurse. Calling the fire department (Choice C) is important but should come after ensuring the client's safety. Closing the door to contain the fire (Choice D) is not appropriate in this scenario because the priority is to remove the client from harm's way.
