What is an early signs of the effect of hypoxemia on the nervous system?
- A. Cyanosis
- B. Restlessness
- C. Tachycardia
- D. Tachypnea
Correct Answer: B
Rationale: The correct answer is B: Restlessness. When the body experiences hypoxemia (low oxygen levels), the brain is deprived of oxygen, leading to early signs such as restlessness. This is due to the brain's attempt to increase oxygen intake by increasing activity. Cyanosis (A) is a late sign of hypoxemia when oxygen levels are critically low. Tachycardia (C) and tachypnea (D) are compensatory mechanisms in response to hypoxemia, but they are not early signs affecting the nervous system directly.

What nursing delivery of care provides the nurse to plan and direct care of a group of clients over a 24-hour period?
- A. Case management.
- B. Team nursing.
- C. Primary nursing.
- D. Functional nursing.
Correct Answer: C
Rationale: The correct answer is C: Primary nursing. Primary nursing is a care delivery model where one nurse is responsible for the total care of a group of clients over a 24-hour period. This promotes continuity of care, individualized attention, and better nurse-client relationships. In primary nursing, the nurse plans and directs care, coordinates with other healthcare team members, and serves as the main point of contact for the clients.
A: Case management involves coordinating care across different healthcare providers and services, not necessarily focusing on a specific group of clients over a 24-hour period.
B: Team nursing involves a team of healthcare providers working together to deliver care, rather than one nurse being responsible for a specific group of clients over a 24-hour period.
D: Functional nursing divides tasks among different healthcare team members based on their specific skills, which may not provide the same level of continuity and individualized care as primary nursing.
A patient receiving palliative care for advanced cancer reports fatigue and loss of appetite. Which intervention should the nurse prioritize?
- A. Encourage the patient to eat small, frequent meals.
- B. Administer prescribed appetite stimulants.
- C. Provide rest periods to reduce fatigue.
- D. Discuss the benefits of parenteral nutrition.
Correct Answer: C
Rationale: The correct answer is C: Provide rest periods to reduce fatigue. Prioritizing rest periods can help alleviate fatigue, a common symptom in patients with advanced cancer. Encouraging small, frequent meals (choice A) may not be effective if the patient has no appetite. Administering appetite stimulants (choice B) may not address the root cause of fatigue. Discussing parenteral nutrition (choice D) is not the priority as it does not directly address the fatigue and loss of appetite reported by the patient. Rest is essential for symptom management and overall well-being in palliative care.
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.
Nociceptors differ from other nerve receptors in the body in what way?
- A. They adapt very little to continual pain response.
- B. They inhibit the infiltration of neutrophils and eosinophils.
- C. They play no role in the inflammatory response.
- D. They transmit only the thermal stimuli.
Correct Answer: A
Rationale: The correct answer is A because nociceptors are specialized nerve receptors that do not adapt much to continual pain response. This lack of adaptation allows nociceptors to continuously signal the presence of tissue-damaging stimuli, which is crucial for the perception of pain. Choices B, C, and D are incorrect because nociceptors do not inhibit the infiltration of neutrophils and eosinophils (B), they do play a role in the inflammatory response (C), and they transmit various types of stimuli including thermal, mechanical, and chemical, not just thermal stimuli (D).
Which of the following nursing activities demonstrates im plementation of the AACN Standards of Professional Performance? (Select all that ap ply.)
- A. Attending a meeting of the local chapter of the Americ an Association of Critical-Care Nurses in which a continuing education program on sepsis is being taught
- B. Collaborating with a pastoral services colleague to assist in meeting spiritual needs of the patient and family
- C. Participating on the unit’s nurse practice council
- D. Posting an article from Critical Care Nurse on manage ment of venous thromboembolism for your colleagues to read
Correct Answer: C
Rationale: The correct answer is C because participating on the unit's nurse practice council demonstrates adherence to the AACN Standards of Professional Performance, specifically the standard related to quality of practice. By actively engaging in the nurse practice council, the nurse contributes to the development and implementation of policies and procedures that promote quality patient care. This activity also involves collaboration, leadership, and advocacy, which are essential components of professional nursing practice.
The other choices are incorrect because:
A: Attending a meeting and receiving continuing education on sepsis is important for professional development but does not directly align with the AACN Standards of Professional Performance.
B: Collaborating with a pastoral services colleague is essential for holistic patient care but does not specifically address the standards set by the AACN.
D: Posting an article for colleagues to read is beneficial for knowledge sharing but does not directly demonstrate adherence to the AACN Standards of Professional Performance.
