Correct Answer: D

Rationale: The correct intervention for the client receiving IV heparin who reports tarry stools and abdominal pain is to monitor the stool for the presence of blood. This is crucial to assess for gastrointestinal bleeding, a potential complication of heparin therapy. Assessing the characteristics of the client's pain may be helpful but is not the priority when signs of GI bleeding are present. Administering warfarin is not appropriate without a thorough assessment and confirmation of the cause of symptoms. While obtaining recent partial thromboplastin time results is important in monitoring heparin therapy, in this scenario, the immediate concern is to assess for possible GI bleeding.

Correct Answer: C

Rationale: The correct intervention for a client with Crohn's disease reporting diarrhea is to encourage a high-fiber diet and regular physical activity. A high-fiber diet helps manage diarrhea in Crohn's disease by adding bulk to the stool and promoting more regular bowel movements. Instructing the client to drink clear fluids and avoid solid foods (Choice A) may not be appropriate as it can further exacerbate diarrhea. Administering antidiarrheal medication (Choice B) without addressing the underlying cause may not be the best initial approach. Encouraging a high-fiber diet and physical activity (Choice C) is beneficial for managing symptoms. Restricting fluid intake and monitoring electrolytes (Choice D) is not recommended as it can lead to dehydration, which is a concern in clients with diarrhea.

Correct Answer: A

Rationale: In a client with chronic heart failure experiencing worsening dyspnea, the priority action for the nurse is to administer oxygen at 2 liters per nasal cannula. This helps improve oxygenation and alleviate respiratory distress. Administering a diuretic (Choice B) may be necessary but addressing oxygenation comes first. While assessing lung sounds (Choice C) is important, it is not the immediate priority when the client is in respiratory distress. Repositioning the client (Choice D) may help with comfort but does not address the underlying issue of inadequate oxygenation.

Correct Answer: D

Rationale: The correct answer is D: 'Use diaphragmatic breathing to achieve better exhalation.' Diaphragmatic breathing is an essential intervention for clients with COPD as it helps improve exhalation and lung function, ultimately reducing symptoms over the long term. Option A is incorrect because high-flow oxygen during sleep is more relevant for clients with conditions like sleep apnea rather than COPD. Option B, 'Reduce risk factors for infection,' is important but not as specific to the long-term management of COPD as diaphragmatic breathing. Option C, 'Limit fluid intake to reduce secretions,' is not a recommended intervention for clients with COPD, as adequate hydration is crucial for maintaining respiratory health.

Correct Answer: A

Rationale: Evaluating the closest proximal pulse is essential when monitoring tissue perfusion post-amputation. This pulse provides crucial information about the circulation and perfusion to the limb. Observing the color and amount of wound drainage (Choice B) is more related to wound healing assessment rather than tissue perfusion. Observing for swelling around the stump (Choice C) may indicate inflammation or infection but is not the most direct assessment of tissue perfusion. Assessing skin elasticity of the stump (Choice D) is important for skin integrity but does not directly reflect tissue perfusion.
