Correct Answer: A

Rationale: The correct answer is to suction the tracheostomy as needed to maintain a patent airway. After a tracheostomy procedure, the immediate concern is airway patency to prevent respiratory compromise. Suctioning helps clear secretions and maintains a clear airway, reducing the risk of respiratory distress. Monitoring the patient's oxygen saturation (choice B) is important but not the priority compared to ensuring a clear airway. Providing humidified air (choice C) and administering pain medication (choice D) are also essential aspects of care for a patient with a tracheostomy, but they are not the priority when immediate airway management is required.

Correct Answer: B

Rationale: The correct answer is B: Nonmaleficence. Nonmaleficence is the ethical principle that emphasizes the obligation to do no harm, making it crucial in medical decision-making. In the context of a bone marrow transplant for a client with leukemia, the primary concern is to minimize harm and avoid causing any unnecessary suffering or adverse effects. Choices A, C, and D are incorrect: Justice relates to fairness in resource allocation and treatment decisions, Autonomy involves respecting the patient's right to make decisions about their own care, and Beneficence refers to the obligation to act in the patient's best interest and promote their well-being, which may involve some level of risk or harm for overall benefit.

Correct Answer: C

Rationale: The correct answer is to lock the wheels on the bed and wheelchair. This action helps prevent accidents by stabilizing the equipment during the transfer process. Having the patient use a gait belt for support (choice A) can be helpful but is not directly related to equipment safety. Encouraging the patient to hold onto a walker (choice B) is beneficial for ambulation but does not address the safety of equipment. Asking the patient to transfer independently (choice D) can pose risks, especially for a patient with limited mobility, and may not ensure safety during the transfer.

Correct Answer: B

Rationale: The correct answer is B. Placing a gait belt around the patient for support is the safest option when assisting a patient to stand from a sitting position. This belt provides stability and support, reducing the risk of falls or injuries during the transfer. Choices A, C, and D are incorrect. Allowing the patient to pull up on the nurse's arm (Choice A) may lead to instability and compromise safety. Having the patient push off the chair with their hands (Choice C) might not provide sufficient support, especially for patients who require assistance. Asking the patient to lift themselves up without support (Choice D) can be dangerous and increase the risk of falls.

Correct Answer: B

Rationale: The correct answer is to assess the patient's blood pressure regularly. Monitoring blood pressure is crucial when administering IV fluids to a dehydrated patient as it helps in evaluating the patient's fluid status. Changes in blood pressure can indicate the effectiveness of the fluid therapy, the patient's response to treatment, and the possibility of complications such as fluid overload or hypovolemia. Monitoring electrolyte levels (Choice A) is essential but not the priority when assessing a dehydrated patient receiving IV fluids. Heart rate (Choice C) should be monitored more frequently than every 4 hours in such a situation. Checking urine output (Choice D) is important but not as critical as assessing blood pressure in this scenario.
