Correct Answer: A

Rationale: The correct answer is A because evaluating morning lab results is crucial to monitor the patient's condition before dialysis. Abnormal results may impact the dialysis treatment plan. Option B is incorrect as administering antihypertensive medications is not directly related to dialysis. Option C is incorrect as assessing the dialysis access site is the responsibility of the dialysis team. Option D is incorrect as weighing the patient is not typically done immediately before dialysis.

Correct Answer: B

Rationale: The correct answer is B because informed consent requires the patient to have knowledge and competence to make a decision. This involves understanding the risks, benefits, and alternatives of the proposed treatment. Choice A is incorrect as it pertains to a physical ability unrelated to decision-making. Choice C is incorrect as consent must be verbal or written, not just nodding. Choice D is incorrect as consent can be obtained in various ways, not specifically through reading and writing in English.

Correct Answer: A

Rationale: The correct answer is A (Pain relief) because palliative care aims to provide comfort and improve the quality of life for individuals with serious illnesses. Pain relief is a crucial goal in palliative care to alleviate physical suffering. Nausea relief (B) is also commonly addressed in palliative care, but it is not a universal goal. Psychological support (C) is an important aspect of palliative care but is not always a primary goal. Withdrawal of life-support interventions (D) is not a goal of palliative care, as palliative care focuses on symptom management and improving quality of life, not hastening death.

Correct Answer: A

Rationale: The correct answer is A: Obtain the permission of the custodial parent for the surgery. In this scenario, the client is a minor (16 years old), which means they are not legally able to provide informed consent for medical procedures. The custodial parent holds legal responsibility for the minor's healthcare decisions. Thus, obtaining the permission of the custodial parent is crucial to ensure valid informed consent. Choice B is incorrect because the non-custodial parent's consent may not be legally required if the custodial parent is available to provide consent. Choice C is incorrect because obtaining consent should precede any administration of medications. Choice D is incorrect as the stepfather's consent may not hold legal weight unless designated as a legal guardian.

Correct Answer: B

Rationale: The correct answer is B: Hemoglobin of 8 g/dL. Low hemoglobin levels can lead to inadequate oxygen delivery to tissues, causing respiratory distress and difficulty weaning from mechanical ventilation. This is due to reduced oxygen-carrying capacity leading to increased work of breathing. A: Cardiac output of 6 L/min is within normal range and not directly related to difficulty weaning from mechanical ventilation. C: Negative sputum culture and sensitivity indicate absence of respiratory infection but not a direct cause of difficulty weaning. D: White blood cell count of 8000 is within normal range and not a direct cause of difficulty weaning.
