Critical Care Nursing Exam Questions Questions

Question 1 of 5

A nurse who works in an intermediate care unit has experienced high nursing turnover. The nurse manager is often considered to be an autocratic leade r by staff members and that leadership style is contributing to turnover. The nurse asks to be involved in developing new guidelines to prevent pressure ulcers in the patient populat ion. The nurse manager suggests that the nurse has not yet had enough experience to be on tahbierb p.croemv/teenstt ion task force. This situation and setting is an example of what form of ineffec tive leadership?

Correct Answer: C

Rationale: The correct answer is C: Displaying ineffective decision making. In this scenario, the nurse manager's decision to exclude the nurse from participating in developing new guidelines is an example of ineffective decision making. By dismissing the nurse's request based on lack of experience rather than considering their input and involvement, the manager is not utilizing the nurse's expertise and potentially missing out on valuable insights. This decision reflects a lack of inclusivity, collaboration, and respect for the nurse's professional growth and potential contributions. The other choices are not directly applicable in this context as the core issue lies in the manager's decision-making process.

Question 2 of 5

The nurse is preparing to obtain a right atrial pressure (RA P/CVP) reading. What are the most appropriate nursing actions? (Select all that apply.)

Correct Answer: A

Rationale: The correct answer is A because comparing measured pressures with other physiological parameters ensures accuracy and consistency. This step helps in interpreting the RA P/CVP reading correctly. Choice B is incorrect as flushing the catheter with saline is not necessary for obtaining the pressure reading. Choice C is incorrect as inflating the balloon with air is not part of the correct procedure. Choice D is incorrect because obtaining the measurement during exhalation can affect the accuracy of the reading.

Question 3 of 5

Which interventions can the nurse use to facilitate communication with patients and families who are in the process of making decisions regarding end- of-life care options? (Select all that apply.)

Correct Answer: A

Rationale: The correct answer is A: Communication of uniform messages from all healthcare team members. This intervention is crucial to ensure consistency in information provided to patients and families, reducing confusion and enhancing trust. When all team members convey the same messages, it helps in clarifying options and facilitating decision-making. Choices B and C are incorrect as they focus on care planning and continuity, which are important but not specifically related to facilitating communication in end-of-life care decisions. Choice D is incorrect as it suggests limiting time for families to express feelings, which can hinder effective communication and support during such a sensitive time.

Question 4 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 5 of 5

The nurse is concerned that a patient is at increased risk of developing a pulmonary embolus and develops a plan of care for prevention to include whic h intervention?

Correct Answer: D

Rationale: The correct answer is D: Mobility. Maintaining mobility helps prevent blood stasis, a leading factor in the development of pulmonary embolism. Movement promotes circulation, reducing the risk of blood clots. A: Antiseptic oral care is important for oral hygiene but not directly related to preventing pulmonary embolism. B: Bed rest with head of bed elevated can actually increase the risk of clots due to immobility. C: Coughing and deep breathing are beneficial for preventing respiratory complications but do not address the underlying cause of pulmonary embolism.
