Question 1 of 5

After attending an educational program, the nurse understaanbidrbs.c othma/tte swt hich the following situations would require an ethics consultation?

Correct Answer: D

Rationale: Step 1: The correct answer is D because the situation involves a patient with multiple trauma who is not responding to treatment and has no known family members. This indicates a complex ethical dilemma where the medical team may be unsure about the appropriate course of action. Step 2: In this scenario, an ethics consultation is necessary to help guide decision-making regarding the care of the patient. The lack of available family members complicates decision-making, and the consideration of care as futile adds another layer of complexity. Step 3: An ethics consultation can provide a structured framework for evaluating the situation, considering ethical principles such as beneficence, non-maleficence, autonomy, and justice. It can help the healthcare team navigate the ethical considerations and make a well-informed decision in the best interest of the patient. Summary: Choice A: While conflicts between the primary care provider and family may warrant discussions, the agreement on a treatment plan does not necessarily require an ethics consultation. Choice B: Disagreement

Question 2 of 5

What is the main purpose of certification for critical care n ursing?

Correct Answer: D

Rationale: The correct answer is D: To validate a nurse�s knowledge of critical care nursing.

This certification ensures that the nurse is well-equipped to provide high-quality care to critically ill patients.

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.

Question 3 of 5

The nurse is assessing a client and identifies a bruit over the thyroid. This finding is consistent with which interpretation?

Correct Answer: D

Rationale: The presence of a bruit over the thyroid indicates increased blood flow, characteristic of hyperthyroidism. This excess blood flow is due to the hypermetabolic state in hyperthyroidism, leading to turbulent blood flow and the audible bruit. A bruit is not typically associated with hypothyroidism, thyroid cysts, or thyroid cancer, as these conditions do not cause increased blood flow. Therefore, the correct interpretation is hyperthyroidism.

Question 4 of 5

The nurse is caring for a 70-kg patient in septic shock with a pulmonary artery catheter. Which hemodynamic value indicates an appropriate response to therapy aimed at enhancing oxygen delivery to the organs and tissues?

Correct Answer: C

Rationale: The correct answer is C: Mixed venous (SvO2) of 40%. In septic shock, improving oxygen delivery to tissues is vital. SvO2 reflects the balance between oxygen delivery and consumption. A value of 40% indicates adequate oxygen delivery to tissues. A: Arterial lactate level of 1.0 mEq/L - Although a low lactate level is good, it does not directly indicate improved oxygen delivery. B: Cardiac output of 2.5 L/min - Cardiac output should ideally increase to improve oxygen delivery, so 2.5 L/min is low for a 70-kg patient. D: Cardiac index of 1.5 L/min/m2 - Cardiac index is cardiac output adjusted for body surface area. 1.5 L/min/m2 is low and indicates inadequate cardiac function for a patient in septic shock.

Question 5 of 5

What should a designated healthcare surrogate base healthcare decisions on?

They are best positioned to understand the patient's condition and treatment options. Personal beliefs (A) may not align with medical best practices. Family and friends' recommendations (B) may not be informed by medical knowledge. Wishes previously expressed by the patient (D) are important but may need to be interpreted in the context of the current medical situation, which healthcare professionals can provide.
