Critical Care Nursing Exam Questions Questions
Question 1 of 5
Continuous venovenous hemofiltration is used to
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.
Question 2 of 5
Complications common to patients receiving hemodialysis for acute kidney injury include which of the following? (Select all that apply.)
Correct Answer: A
Rationale: The correct answer is A, hypotension. During hemodialysis for acute kidney injury, fluid removal can lead to hypotension due to rapid changes in blood volume. This can cause dizziness, weakness, and even loss of consciousness. Dysrhythmias (choice B) are less common but can occur due to electrolyte imbalances. Muscle cramps (choice C) may occur during or after dialysis due to electrolyte imbalances or fluid shifts, but they are not as common as hypotension. Hemolysis (choice D) is not a common complication of hemodialysis for acute kidney injury, as it is more commonly associated with issues related to the dialysis machine or blood tubing.
Question 3 of 5
An 80-year-old client is given morphine sulphate for postoperative pain. Which concomitant medication should the nurse question that poses a potential development of urinary retention in this geriatric client?
Correct Answer: B
Rationale: The correct answer is B: Tricyclic antidepressants. Tricyclic antidepressants can cause anticholinergic effects, including urinary retention, especially in the elderly. Morphine sulfate can also contribute to urinary retention. Antacids (A) and nonsteroidal anti-inflammatory agents (C) are not known to cause urinary retention. Insulin (D) does not pose a risk for urinary retention in this scenario.
Question 4 of 5
Which intervention should the nurse include in the plan of care for a female client with severe postpartum depression who is admitted to the inpatient psychiatric unit?
Correct Answer: C
Rationale: The correct answer is C because supervised and guided visits with the infant allow the client to bond with her baby in a safe and structured environment, promoting maternal-infant attachment while ensuring the safety and well-being of both. Restricting visitors who irritate the client (choice A) may increase feelings of isolation and distress. Full rooming-in for the infant and mother (choice B) may overwhelm the client with severe postpartum depression. Daily visits with her significant other (choice D) may not directly address the client's need for bonding with her infant.
Question 5 of 5
What nursing delivery of care provides the nurse to plan and direct care of a group of clients over a 24-hour period?
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.
