Correct Answer: B

Rationale: The priority nursing intervention for a client with COPD experiencing shortness of breath is to position the client in a high-Fowler's position. This position helps improve lung expansion and breathing by reducing respiratory effort. Administering a high-flow oxygen mask (Choice A) may be necessary but is not the priority intervention. Providing a high-carbohydrate diet (Choice C) is not directly related to managing acute shortness of breath in COPD. Encouraging the client to cough and deep breathe (Choice D) is helpful for airway clearance but is not the priority intervention when the client is in distress with acute shortness of breath.

Correct Answer: C

Rationale: The priority nursing intervention for a client with COPD experiencing shortness of breath is to position the client in a high-Fowler's position. This position helps improve lung expansion and ease breathing in COPD patients. While administering bronchodilator therapy as prescribed (Choice A) is important, it is not the priority in this scenario. Encouraging deep breathing and coughing exercises (Choice B) can be beneficial but do not take precedence over positioning for improved respiratory function. Increasing the oxygen flow rate (Choice D) can be considered after the initial positioning to relieve respiratory distress, making it a later intervention.

Correct Answer: C

Rationale: The correct way to apply tape to anchor an eye shield effectively is to attach the tape from the lower eyelid to the upper forehead. This method provides stability for the shield without putting pressure on the eye itself, thus helping to protect the eye. Choices A, B, and D are incorrect because taping from the cheek to the forehead, securing tape from the nose to the ear, or using circular bandaging around the head may not provide the necessary stability and protection required for the eye shield.

Correct Answer: C

Rationale: The correct intervention for the nurse to implement is to add sterile water to the suction control chamber. This action helps maintain the proper functioning of the chest tube system by regulating the negative pressure. Increasing wall suction is not recommended as it could lead to excessive negative pressure. Giving blood from the collection chamber as autotransfusion is inappropriate and poses a risk of complications such as air embolism. Manipulating blood in the tubing is also unsafe as it could introduce air into the system, increasing the risk of complications for the client.

Correct Answer: D

Rationale: Heart rate, stroke volume, and peripheral resistance are indeed key parameters that directly influence blood pressure. Heart rate refers to the number of times the heart beats per minute, affecting how much blood is pumped. Stroke volume is the amount of blood pumped by the heart in one contraction. Peripheral resistance is the resistance of the arteries to blood flow, impacting the pressure needed to push blood through. Neuroendocrine hormones, while they can indirectly influence blood pressure regulation by affecting factors like blood volume and vascular tone, are not direct final parameters that produce blood pressure.
