Correct Answer: B

Rationale: The correct answer is B: sitting at the side of the bed with both arms resting on a locked overbed table. This position allows for better lung expansion and easier access to the thoracic cavity during the procedure. Sitting position helps in maximizing lung volume and facilitates drainage of pleural effusion. Arms resting on a locked overbed table helps the patient maintain a stable position and reduces the risk of movement during the procedure. Other choices are incorrect because supine position (A) may not allow for optimal lung expansion, high fowler's position (C) may not provide easy access to the thoracic cavity, and semi-fowlers position (D) may not facilitate efficient drainage of pleural effusion.

Correct Answer: C

Rationale: The correct answer is C: Staying at patient's bedside. This is the most helpful nursing action because it provides reassurance and support to the anxious patient experiencing dyspnea. By staying at the bedside, the nurse can monitor the patient closely, provide immediate assistance if needed, and offer a calming presence. Explanation of why other choices are incorrect: A: Increasing activity levels may worsen the dyspnea and anxiety of the patient. B: Pulling the privacy curtain does not directly address the patient's anxiety or dyspnea. D: Closing the patient's door may make the patient feel isolated and increase anxiety. In summary, staying at the patient's bedside is the most effective nursing action as it addresses both the physical and emotional needs of the anxious patient with dyspnea.

Correct Answer: A

Rationale: The correct answer is A: "Would you like to talk to a psychologist about your thoughts and feelings?" This response acknowledges the client's emotional distress and offers professional support. A psychologist can provide counseling and help the client explore their feelings and concerns about end-of-life decisions. Choice B is incorrect because it assumes the client's spiritual beliefs are the primary concern, neglecting the emotional and psychological aspects. Choice C involves more people in the decision-making process without addressing the client's individual needs. Choice D is dismissive and does not offer any support or explore the client's feelings further. In summary, choice A is the best response because it prioritizes the client's emotional well-being and offers appropriate support through professional counseling.

Correct Answer: A

Rationale: The correct answer is A because it demonstrates data validation in making a nursing clinical decision. The nurse assesses the time of the last dressing change and compares it with the appearance of old and new drainage. This process ensures that the decision to remove the wound dressing is based on accurate and validated data, leading to appropriate patient care. Choice B is incorrect because it does not involve data validation. The decision is driven by increased pain and family requests, without verifying the underlying cause. Choice C is incorrect as it involves responding to a patient's reported symptom (leg cramps), but it does not involve data validation in making the clinical decision. Choice D is incorrect as it relies solely on the patient's report of decreased mobility without further data validation.

Correct Answer: B

Rationale: The correct answer is B: 20,000/ul. A platelet count below 20,000/ul puts the client at the highest risk for cerebral hemorrhage due to severe thrombocytopenia. Platelets are essential for blood clotting, and a low count increases the risk of spontaneous bleeding, especially in critical organs like the brain. Choices A, C, and D have platelet counts that are higher than the critical level of 20,000/ul, so they do not pose as high a risk for cerebral hemorrhage. Option D, 500/ul, is extremely low and would likely lead to severe bleeding, but the critical threshold for cerebral hemorrhage is considered to be around 20,000/ul.
