Correct Answer: A

Rationale: The correct instruction the nurse should include is to 'Use pursed-lip breathing during physical activity.' Pursed-lip breathing is a technique that helps improve breathing efficiency in individuals with COPD by preventing airway collapse and allowing for better air exchange. Choice B is incorrect because breathing deeply and quickly can lead to hyperventilation and worsen symptoms in COPD patients. Choice C is incorrect because the incentive spirometer is a device used to encourage deep breathing and improve lung function, so it should not be avoided. Choice D is incorrect because physical activity is important for maintaining overall health and should be encouraged in a controlled and appropriate manner for individuals with COPD.

Correct Answer: B

Rationale: When a client develops redness and warmth at the IV site, it is indicative of phlebitis, which is inflammation of the vein. The next step for the nurse should be to discontinue the IV and notify the healthcare provider. Applying a cold compress may provide temporary relief but does not address the underlying issue. Monitoring for infection is important, but in this case, the presence of redness and warmth suggests phlebitis, not infection. Increasing the IV flow rate can exacerbate the inflammation and should be avoided.

Correct Answer: A

Rationale: A below-the-knee amputation requires immediate attention due to the risk of hemorrhage and shock, making it the highest priority. This type of injury can lead to significant blood loss and impaired perfusion, which can be life-threatening if not addressed promptly. While a 10 cm laceration, a fractured tibia, and a 95% full-thickness body burn are serious injuries requiring urgent care, they do not pose the same immediate threat to life as a below-the-knee amputation. The laceration may require suturing to control bleeding and prevent infection, the fractured tibia needs stabilization to prevent further damage and pain, and the burn necessitates immediate management to prevent complications, but they are not as acutely life-threatening as the amputation.

Correct Answer: D

Rationale: After surgery, key signs of infection include redness, swelling, and fever. Redness and swelling can indicate inflammation at the surgical site, while fever is a systemic response to infection. Choosing 'All of the above' (Option D) is the correct answer because all three signs are commonly associated with post-surgical infections. Options A, B, and C are incorrect as each of them individually can be a sign of infection, but considering all three together provides a more comprehensive assessment for post-operative infection.

Correct Answer: A

Rationale: The correct answer is A: Monitor gastric residual volume and check for abdominal distension. These assessments are critical to evaluate the patient's tolerance to enteral feeding. Monitoring gastric residual volume helps determine gastric emptying, while checking for abdominal distension can identify complications like bowel obstruction. Choices B, C, and D are important aspects of enteral feeding care but are not the primary assessments. Ensuring the correct placement of the feeding tube is crucial for safety, assessing for signs of dehydration and electrolyte imbalances is essential for overall patient well-being, and elevating the head of the bed is vital to prevent aspiration. However, these are not the key assessments specifically related to enteral feeding.
