Correct Answer: B

Rationale: Practicing pursed-lip breathing is an essential technique to help manage COPD as it can improve oxygenation by promoting better gas exchange. This technique helps to keep the airways open longer during exhalation, preventing air trapping and improving breathing efficiency. Increasing fluid intake can help thin secretions, which is beneficial, but it is not the primary instruction for managing COPD. Avoiding physical activity is not recommended as it can lead to deconditioning and worsen dyspnea in COPD patients. Using a peak flow meter is more commonly associated with monitoring asthma rather than COPD, so it is not the most relevant instruction for managing COPD.

Correct Answer: D

Rationale: The high-Fowler position is preferred after neck surgery to reduce edema at the operative site. Elevating the head of the bed promotes venous return and drainage, aiding in decreasing swelling and fluid accumulation, which helps reduce edema at the operative site. Choice A is incorrect as the main purpose is not solely about reducing strain on the incision. Choice B is incorrect because while drainage may occur, it is not the primary reason for maintaining the high-Fowler position. Choice C is incorrect as providing stimulation is not the primary rationale for positioning the client in high-Fowler.

Correct Answer: C

Rationale: The correct answer is C: Friction. The amount of friction is crucial in effective hand hygiene to remove microorganisms. Rubbing hands together with friction helps to dislodge and remove dirt, oils, and microorganisms. While temperature and soap are important factors in hand hygiene, the mechanical action of friction plays a more significant role in physically removing contaminants. Time is also important in hand hygiene practice, but without adequate friction, the effectiveness of the process is compromised.

Correct Answer: D

Rationale: Maintaining sterile technique when handling a central venous catheter is crucial in preventing infections. This action helps minimize the introduction of pathogens into the catheter site, reducing the risk of contamination and subsequent infection. Changing the catheter dressing every 72 hours, while important, does not directly address the prevention of infection at the insertion site. Flushing the catheter with heparin solution daily helps prevent occlusion but does not primarily focus on infection prevention. Ensuring the catheter is clamped when not in use is essential for preventing air embolism but does not directly relate to infection control.

Correct Answer: C

Rationale: The correct answer is C. Soaking the feet in warm water daily is not recommended for clients with diabetes as it can cause the skin to become too soft, increasing the risk of skin breakdown and infections. Checking the feet daily for cuts or sores (A) is a good practice to prevent complications. Avoiding walking barefoot (B) helps protect the feet from injuries. Wearing well-fitted shoes (D) is essential to prevent blisters and other foot problems in diabetic clients. Therefore, the client's statement about soaking the feet in warm water daily indicates a need for further teaching.
