Nokea
represent?
- A. Alveolar oxygen tension.
- B. Oxygen that is chemically combined with hemoglobin .
- C. Oxygen that is physically dissolved in plasma.
- D. Total oxygen consumption.
Correct Answer: B
Rationale: The correct answer is B: Oxygen that is chemically combined with hemoglobin. This is because oxygen primarily travels in the blood by binding to hemoglobin in red blood cells, forming oxyhemoglobin. This process allows for efficient transport of oxygen to tissues throughout the body. Choices A, C, and D are incorrect because:
A: Alveolar oxygen tension refers to the partial pressure of oxygen in the alveoli of the lungs, not the specific form of oxygen in the blood.
C: Oxygen physically dissolved in plasma refers to the small amount of oxygen that is not bound to hemoglobin and is less significant in oxygen transport compared to oxygen bound to hemoglobin.
D: Total oxygen consumption is the overall amount of oxygen utilized by the body, not specifically the form of oxygen bound to hemoglobin for transport.

A patient is experiencing severe pain, despite receiving pain medication for the past 24 hours. The patients wife expresses concern about this to the nurse. Which response by the nurse would be most empowering to the patients family?
- A. Explain that the doctor is an expert on pain medication and that the current level ofm edication is the best.
- B. Recommend that the family members take turns massaging the patients feet todistract from the pain.
- C. Encourage the family to request that the physician evaluate the patients pain control.
- D. Ask the family to wait another 24 hours to see whether the patients pain level will go down.
Correct Answer: C
Rationale: The correct answer is C because it empowers the family to take action by requesting a physician evaluation of the patient's pain control. This step is crucial in ensuring that the patient's pain is adequately managed. By involving the physician, the family can advocate for the patient's needs and potentially explore alternative pain management strategies.
Choice A is incorrect because it dismisses the family's concerns and fails to address the need for further evaluation. Choice B may provide temporary relief but does not address the underlying issue of inadequate pain control. Choice D is incorrect as it suggests delaying action, which could lead to prolonged suffering for the patient.
A nurse walks into a patients room and begins preparing a syringe to perform a blood draw on the patient. The nurse observes that the patient is firmly gripping the side of the bed, averting her eyes, and sweating from her forehead when she sees the needle. What would be the best intervention for the nurse to make?
- A. Proceed with blood draw as quickly as possible, to get it over with.
- B. Offer to come back later to perform the blood draw.
- C. Encourage the patient to deep breathe.
- D. Describe briefly the blood draw procedure and explain why it is necessary.
Correct Answer: D
Rationale: The correct answer is D because it shows empathy and promotes patient education. By describing the procedure and its necessity, the nurse can alleviate the patient's anxiety and build trust. This approach allows the patient to feel informed and in control, reducing fear and increasing cooperation. It also demonstrates respect for the patient's feelings and promotes a therapeutic relationship.
Choice A is incorrect as it disregards the patient's fear and can lead to increased distress. Choice B might be an option, but it doesn't address the patient's anxiety in the moment. Choice C, while helpful in some cases, doesn't directly address the patient's specific fear of the blood draw procedure.
The family members are excited about being transferring t heir loved one from the critical care unit to the intermediate care unit. However, they are also fearful of the change in environment and nursing staff. To reduce relocation stress, the nurse ca n implement what intervention? (Select all that apply.)
- A. Arranging for the nurses on the intermediate care unit to give the family a tour of the new unit.
- B. Contacting the primary care provider to see if the patient can stay one additional day in the critical care unit so that the family can adjus t better to the idea of a transfer.
- C. Ensuring that the patient will be located near the nurse ’s station in the new unit.
- D. Inviting the nurse who will be assuming the patient’s care to meet with the patient and family in the critical care unit prior to transfer.
Correct Answer: A
Rationale: The correct answer is A (Arranging for the nurses on the intermediate care unit to give the family a tour of the new unit) because it helps familiarize the family with the new environment, alleviating their fears. The tour allows them to see where their loved one will be cared for, meet the nursing staff, and ask any questions they may have. This intervention promotes a smooth transition, reduces anxiety, and builds trust.
Choice B is incorrect because delaying the transfer doesn't address the fear of change and can prolong stress. Choice C is incorrect as proximity to the nurse's station may not necessarily reduce relocation stress for the family. Choice D is incorrect because meeting the new nurse in the current unit may not provide the same level of comfort and preparation compared to physically visiting the new unit.
Continuous venovenous hemofiltration is used to
- A. remove fluids and solutes through the process of convection.
- B. remove plasma water in cases of volume overload.
- C. remove plasma water and solutes by adding dialysate.
- D. combine ultrafiltration, convection, and dialysis.
Correct Answer: A
Rationale: The correct answer is A because continuous venovenous hemofiltration (CVVH) primarily removes fluids and solutes through the process of convection. In CVVH, blood flows through a filter where hydrostatic pressure drives plasma water and solutes across a semipermeable membrane. This process mimics the natural filtration that occurs in the kidneys. Choice B is incorrect because CVVH does not specifically target plasma water only but also removes solutes. Choice C is incorrect because CVVH does not involve adding dialysate to remove plasma water and solutes. Choice D is incorrect because while CVVH may involve ultrafiltration and convection, it does not typically include dialysis as a primary mechanism for solute removal.
What is the main purpose of certification for critical care n ursing?
- A. To assure the consumer that critical nurses will not make a mistake.
- B. To help prepare the critical care nurse for graduate sch ool.
- C. To assist in promoting magnet status for a facility.
- D. To validate a nurse’s knowledge of critical care nursing
Correct Answer: D
Rationale: The correct answer is D: To validate a nurse’s knowledge of critical care nursing. Certification in critical care nursing validates a nurse's expertise and knowledge in this specialized area of nursing. It demonstrates that the nurse has met certain standards and competencies in critical care practice. This certification ensures that the nurse is well-equipped to provide high-quality care to critically ill patients.
A: To assure the consumer that critical nurses will not make a mistake - This choice is incorrect because certification does not guarantee that nurses will not make mistakes. It focuses on validating knowledge and skills rather than infallibility.
B: To help prepare the critical care nurse for graduate school - This choice is incorrect as certification is more focused on practice readiness rather than academic preparation.
C: To assist in promoting magnet status for a facility - This choice is incorrect as magnet status relates more to the overall excellence and quality of nursing care in a facility, not individual certification.
