Correct Answer: C

Rationale: The correct answer is C: Staying at patient's bedside. This is the most helpful nursing action because it provides reassurance and support to the anxious patient experiencing dyspnea. By staying at the bedside, the nurse can monitor the patient closely, provide immediate assistance if needed, and offer a calming presence. Explanation of why other choices are incorrect: A: Increasing activity levels may worsen the dyspnea and anxiety of the patient. B: Pulling the privacy curtain does not directly address the patient's anxiety or dyspnea. D: Closing the patient's door may make the patient feel isolated and increase anxiety. In summary, staying at the patient's bedside is the most effective nursing action as it addresses both the physical and emotional needs of the anxious patient with dyspnea.

Correct Answer: C

Rationale: The correct answer is C: Auscultate lung sounds. By auscultating lung sounds, the nurse can assess for changes in breath sounds which can indicate improvement or deterioration in the patient's condition. This helps monitor the effectiveness of therapy for a pneumothorax and chest-drainage system. Palpating for crepitus (A) is not directly related to monitoring therapy effectiveness. Documenting sputum color and amount (B) is important but does not specifically monitor therapy effectiveness. Monitoring suction level (D) is crucial but does not directly assess the patient's response to therapy.

Correct Answer: B

Rationale: The correct answer is B: The potential complication. In a collaborative problem, the focus of a diagnostic statement should be on identifying any potential complications that may arise due to the client's condition or treatment. This allows nurses and other healthcare professionals to anticipate and address these complications proactively. A: The client problem - While important, the client problem is usually addressed in the nursing diagnosis rather than the diagnostic statement for a collaborative problem. C: The nursing diagnosis - The nursing diagnosis focuses on the actual or potential health problems that the client is experiencing, which is different from the focus of a diagnostic statement for a collaborative problem. D: The medical diagnosis - The medical diagnosis is the identification of a disease or condition by a healthcare provider, which is not the focus when identifying potential complications in a collaborative problem.

Correct Answer: C

Rationale: The correct answer is C: Observe wound appearance and edges. This is the first intervention the nurse should perform because assessing the wound's appearance and edges provides crucial information about the healing process and any signs of infection. It helps in determining the next steps in the care plan. Reinforcing the dressing (A) and performing dressing changes (B) should come after assessing the wound. Documenting wound characteristics (D) is important but should also follow the initial assessment.

Correct Answer: B

Rationale: The correct answer is B: It minimizes the risk of circulatory overload. When a venous access device dislodges during a transfusion, there is a risk of the infusion going into the surrounding tissues instead of the vein, leading to circulatory overload. This can result in fluid overload and potentially lead to serious complications such as heart failure. Monitoring the device ensures that the medication is delivered safely and effectively into the bloodstream. Choices A, C, and D are incorrect: A: Monitoring the device does not directly minimize the risk of phlebitis, which is inflammation of the vein. C: Monitoring the device does not directly minimize the risk of pulmonary complications, which are not typically associated with a dislodged venous access device. D: Monitoring the device does not directly minimize the risk of localized edema embolism, which is a blockage caused by a blood clot, air bubble, or other material in a blood vessel.
