Correct Answer: A

Rationale: The correct answer is A: Administering diuretics as prescribed. Diuretics help reduce fluid retention in patients with heart failure, relieving symptoms like edema and shortness of breath. Prioritizing diuretics can help manage the patient's fluid balance and improve heart function. Encouraging increased fluid intake (B) is contraindicated as it can worsen fluid overload. Restricting sodium intake (C) is important in heart failure management but not the top priority over administering diuretics. Administering pain medications (D) is not a priority intervention for chronic heart failure management.

Correct Answer: D

Rationale: The correct answer is D: Increasing caffeine consumption. Caffeine can potentially raise blood pressure in individuals with hypertension. The rationale is that caffeine is a stimulant that can lead to temporary spikes in blood pressure. This can be harmful for patients with a history of hypertension as it can exacerbate their condition. A: Increasing potassium intake is generally recommended for individuals with hypertension as it can help lower blood pressure. B: Consuming more fruits and vegetables is also beneficial for hypertension due to their high fiber and nutrient content. C: Limiting sodium intake is crucial for managing hypertension as high sodium levels can lead to increased blood pressure. In summary, increasing caffeine consumption is the correct answer to avoid for patients with hypertension, as it can potentially worsen their condition by raising blood pressure.

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 it involves a specific and observable task that assesses attention span. By asking the patient to perform a physical action that requires focus and coordination, the nurse can directly evaluate the patient's ability to follow instructions and maintain attention. This task also helps to assess motor skills and coordination, which can be affected in certain conditions associated with anxiety and restlessness. Choices A, B, and C are incorrect because they do not directly assess attention span. Choice A focuses on emotions and behavior rather than attention. Choice B assesses memory recall rather than attention span. Choice C tests comprehension and interpretation skills related to a phrase, but it does not evaluate attention span directly.

Correct Answer: A

Rationale: The correct answer is A because it reflects the shift towards a holistic view of health focusing on preventive measures and lifestyle choices. In the 1950s, the emphasis was more on treating diseases rather than preventing them through healthy habits. Choice B is incorrect as it only focuses on identifying pathogens, not overall health. Choice C is incorrect because it emphasizes physician-centered healthcare rather than individual responsibility. Choice D is incorrect as it only considers the absence of symptoms, not overall well-being. Therefore, A is the best choice as it aligns with the modern understanding of health promotion and disease prevention.
