Correct Answer: D

Rationale: When managing a client with generalized anxiety disorder (GAD), a primary goal is to teach relaxation techniques to help manage anxiety. Relaxation techniques such as deep breathing, progressive muscle relaxation, and mindfulness can be effective in reducing anxiety symptoms. Encouraging the client to engage in regular physical exercise (Choice A) can be beneficial but teaching relaxation techniques is more specific to managing anxiety. Avoiding anxiety triggers through behavioral therapy (Choice B) may be part of the treatment plan but teaching relaxation techniques is more directly aimed at managing anxiety. While encouraging the client to express feelings openly (Choice C) can be important for overall emotional well-being, teaching relaxation techniques is more focused on addressing the symptoms of anxiety.

Correct Answer: D

Rationale: Proper documentation of chest tube output is crucial in the care of a patient with a chest tube. While ensuring the chest tube is secured and functioning, checking for air leaks, and maintaining drainage below chest level are important aspects of care, documentation of output is essential for monitoring the patient's condition, assessing the effectiveness of treatment, and ensuring appropriate interventions if needed.

Correct Answer: A

Rationale: Central cyanosis is best assessed by examining the oral mucosa, as it is a more reliable indicator compared to other areas like the conjunctivae, soles of the feet, and ear lobes. The oral mucosa reflects the oxygen saturation levels of the blood more accurately. Conjunctivae and ear lobes may show cyanosis, but they are not as reliable as the oral mucosa. The soles of the feet are not typically used to assess central cyanosis.

Correct Answer: C

Rationale: Preventing aspiration is the priority when caring for a client who is vomiting to reduce the risk of pneumonia or other respiratory complications. Aspiration can occur when vomitus enters the airway, leading to respiratory distress. Ensuring the airway is protected during vomiting episodes is essential. Administering an antiemetic (Choice A) can be considered after addressing the immediate risk of aspiration. Notifying housekeeping (Choice B) and providing an emesis basin (Choice D) are important but are secondary to preventing aspiration, which is crucial for the client's safety and well-being.

Correct Answer: B

Rationale: When a client has edema of both hands and thickened toenails, these conditions can impede accurate readings from the finger and toe locations. The earlobe is the best alternative site for the pulse oximeter probe in this scenario. Placing the probe on the earlobe will help ensure a more accurate measurement of oxygen saturation despite the issues with the hands and toenails. Therefore, the correct answer is to apply the pulse oximeter probe to the earlobe. Choices A, C, and D are incorrect because of the potential limitations presented by the edema and thickened toenails.
