Correct Answer: A

Rationale: The correct answer is A: Place the client in a safe environment. This is the primary intervention for a client with a history of falls to prevent further injury. By ensuring the environment is safe, the risk of falls and subsequent injuries is minimized. Choice B, assessing the client's functional status, is important but not the primary intervention. Choice C, encouraging the client to rest, may not address the underlying issue of fall risk. Choice D, encouraging the client to ambulate, may increase the risk of falls for someone with a history of falls. It is crucial to prioritize safety by modifying the environment to prevent falls.

Correct Answer: D

Rationale: The correct answer is D: Their sensory-perceptive abilities. Assessing sensory-perceptive abilities is crucial in older adults as sensory impairments can mimic signs of mental health issues. By assessing sensory functions first, the nurse can rule out any physical factors influencing the assessment. Phobias (A) and irrational thinking patterns (C) are psychological aspects that come after ruling out sensory issues. General intelligence (B) may not be the priority as cognitive decline can be affected by sensory impairments.

Correct Answer: B

Rationale: The correct answer is B because building trust with patients is crucial for effective communication and promoting patient cooperation. Trust takes time to develop and is essential in gaining accurate information about a patient's health. Patients may not disclose all information if they do not trust the nurse. Choice A is incorrect because patients may withhold information for various reasons. Choice C is incorrect as not all patients seeking care may fully understand the Canadian health care system. Choice D is incorrect because not all patients may recognize the importance of answering all questions, especially if they are uncomfortable or lack trust in the healthcare provider.

Correct Answer: A

Rationale: The correct answer is A: Administer anticoagulants. This is crucial for preventing blood clots post-surgery as they help thin the blood and reduce clot formation. Monitoring for arrhythmias (B) is important but not the priority in this case. While encouraging deep breathing (C) and fluid intake (D) are beneficial for post-surgical recovery, they do not directly address the risk of blood clot formation. Administering anticoagulants is the most effective intervention to prevent blood clots in high-risk surgical patients.

Correct Answer: A

Rationale: The correct answer is A: Administer IV fluids. Dehydration and hypotension indicate fluid loss, which can lead to organ damage and shock. Administering IV fluids helps restore blood volume and improve blood pressure. Monitoring blood pressure (B) is important but addressing the underlying issue of fluid loss is crucial. Administering antihypertensive medications (C) would further lower blood pressure, worsening hypotension. Administering diuretics (D) would exacerbate fluid loss, worsening dehydration and hypotension.
