Correct Answer: D

Rationale: The correct answer is D: Pitting edema and weight gain. In chronic heart failure, worsening symptoms indicate fluid retention. Pitting edema in the extremities and weight gain are signs of fluid overload, indicating worsening heart failure. It is crucial for the nurse to monitor these signs to prevent exacerbation. Fatigue and shortness of breath (Choice A) are common symptoms in heart failure but not specific to worsening condition. Increased urine output (Choice B) is not typically seen in worsening heart failure as the kidneys may be compromised. Decreased blood pressure (Choice C) can occur in acute decompensation but is not a consistent sign of worsening chronic heart failure.

Correct Answer: B

Rationale: The correct answer is B: Bleeding or perforation. After a colonoscopy, the patient is at risk for bleeding or perforation which are serious complications requiring immediate attention. Monitoring for signs such as abdominal pain, rectal bleeding, or signs of peritonitis is crucial. Choice A is not a priority unless the patient shows signs of shock. Choice C is a common post-procedure issue but not a priority complication. Choice D, pain at the insertion site, is expected and can be managed with analgesics.

Correct Answer: D

Rationale: The correct answer is D because the patient is showing signs of expressive aphasia, where they have difficulty with verbal expression. By supporting his efforts to communicate and using pantomime and gestures, the nurse can help bridge the communication gap and facilitate understanding. This approach acknowledges the patient's drive to communicate and helps him convey his thoughts effectively. Option A is incorrect because although the patient may understand, the nurse needs to adapt the communication method to support the patient's expressive difficulties. Option B is incorrect as abandoning communication efforts would be detrimental to the patient's well-being and recovery. Option C is incorrect as the patient's ability to read and write may also be impaired due to the stroke, making this method less effective than using gestures and pantomime.

Correct Answer: C

Rationale: The correct answer is C because stopping the inhaler once feeling better is incorrect. Inhalers are used to manage COPD symptoms long-term, not just when feeling unwell. Step 1: Explain that inhalers are essential for managing COPD and should be used consistently. Step 2: Emphasize that stopping inhaler use prematurely can lead to exacerbation of symptoms and worsening of the condition. Step 3: Reinforce the importance of following the prescribed treatment plan for optimal COPD management. Other choices are incorrect: A: True, avoiding second-hand smoke is crucial for COPD management. B: True, taking medications as prescribed is essential. D: True, breathing exercises can help improve lung function.

Correct Answer: B

Rationale: The correct answer is B: 1.5 m. This distance is known as the personal distance in communication, where most interviews take place. Personal distance allows for a comfortable level of interaction without invading personal space. Choice A (1 m) is too close and may make the patient uncomfortable. Choice C (2 m) is too far for an intimate interview setting. Choice D (3 m) is too distant and may lead to a lack of connection and understanding during the interview. Overall, B is the best choice for a nurse-patient interview to ensure a respectful and effective conversation.
