A 20-year-old patient arrives in the emergency department (ED) several hours after taking 25 to 30 acetaminophen (Tylenol) tablets. Which action will the nurse plan to take?
- A. Give N-acetylcysteine (Mucomyst).
- B. Discuss the use of chelation therapy.
- C. Start oxygen using a non-rebreather mask.
- D. Have the patient drink large amounts of water.
Correct Answer: A
Rationale: The correct answer is A: Give N-acetylcysteine (Mucomyst). N-acetylcysteine is the antidote for acetaminophen overdose. It helps replenish glutathione, which is depleted by acetaminophen metabolism. This prevents liver damage. Choice B, chelation therapy, is not indicated for acetaminophen overdose. Choice C, oxygen therapy, is not directly related to acetaminophen overdose treatment. Choice D, drinking water, will not address the overdose and may not be safe in high doses. Therefore, the best course of action is to administer N-acetylcysteine to prevent liver damage in acetaminophen overdose.

A patient with respiratory failure has arterial pressure-based cardiac output (APCO) monitoring and is receiving mechanical ventilation with peak end-expiratory pressure (PEEP) of 12 cm H2O. Which information indicates that a change in the ventilator settings may be required?
- A. The arterial pressure is 90/46.
- B. The heart rate is 58 beats/minute.
- C. The stroke volume is increased.
- D. The stroke volume variation is 12%.
Correct Answer: A
Rationale: The correct answer is A. A decrease in the arterial pressure (hypotension) with a low diastolic pressure (46 mmHg) may indicate inadequate perfusion, possibly due to inadequate cardiac output from the mechanical ventilation. This suggests that a change in ventilator settings may be required to improve oxygenation and perfusion.
Option B is incorrect because a heart rate of 58 beats/minute alone does not provide direct information on the patient's hemodynamic status. Option C is incorrect as an increased stroke volume would usually be a positive indicator; it does not necessarily indicate a need for changing the ventilator settings. Option D is incorrect as a stroke volume variation of 12% is within normal limits and does not necessarily require a change in ventilator settings.
The nurse understands that many strategies are available to address ethical issues that may occur; these strategies include which of the following? (Select all that apply.)
- A. Change-of-shift report updates
- B. Ethics consultation services
- C. Formal multiprofessional ethics committees
- D. Pastoral care services
Correct Answer: B
Rationale: The correct answer is B: Ethics consultation services. These services involve seeking guidance from experts to navigate complex ethical dilemmas. They provide in-depth analysis and recommendations based on ethical principles, helping healthcare professionals make informed decisions. Change-of-shift report updates (A) are essential for continuity of care but do not directly address ethical issues. Formal multiprofessional ethics committees (C) are valuable for reviewing policies and addressing systemic ethical concerns but may not be readily available for immediate guidance. Pastoral care services (D) offer spiritual support but may not always have the expertise to handle complex ethical dilemmas. Ethics consultation services (B) are the most suitable option for addressing specific ethical issues promptly and effectively.
Which statement reflects adherence to current recommendations concerning open visitation policies?
- A. Allowing animals on the unit; however, these can only be “therapy” animals through the hospital’s pet therapy program.
- B. Allowing family visitation throughout the day except a t change of shift and during rounds.
- C. Determining, in collaboration with the patient and famaiblyirb, .cwomho/te csta n visit and when.
- D. Permitting open visitation by adults 18 years of age and older; limit visits of children to 1 hour.
Correct Answer: C
Rationale: The correct answer is C because it reflects patient-centered care by involving patients and families in decision-making. Collaborating with them on visitation preferences promotes a supportive environment. Choice A restricts animal visitation, not addressing human visitors. Choice B limits visitation during specific times, not individualized. Choice D imposes restrictions based on age, not on patient/family preferences. Therefore, Choice C is the most aligned with current recommendations for open visitation policies.
A critically ill patient is not expected to survive this admission. The family asks the nurse how the patient is doing. When answering this question, what should the nurse include?
- A. Emphasize that the patient is young and strong and may still survive.
- B. Refer the family to the physician for all details and answers.
- C. Give specific information such as descending trends in parameters.
- D. Ask if the family has determined which funeral home will be called.
Correct Answer: C
Rationale: The correct answer is C because providing specific information such as descending trends in parameters helps the family understand the patient's condition objectively. This allows them to prepare emotionally and make informed decisions. Option A is incorrect because false hope should not be given. Option B is not the best approach as the nurse should still provide some information to the family. Option D is inappropriate and insensitive as it focuses on funeral arrangements rather than addressing the family's concerns about the patient's condition.
Continuous renal replacement therapy (CRRT) differs from conventional intermittent hemodialysis in that
- A. a hemofilter is used to facilitate ultrafiltration.
- B. it provides faster removal of solute and water.
- C. it does not allow diffusion to occur.
- D. the process removes solutes and water slowly.
Correct Answer: D
Rationale: The correct answer is D because CRRT removes solutes and water slowly, which is beneficial for hemodynamically unstable patients. This slow removal allows for gradual fluid and electrolyte balance adjustments, reducing the risk of hemodynamic instability.
A: Incorrect - A hemofilter is indeed used in CRRT, but this choice does not highlight the key difference between CRRT and intermittent hemodialysis.
B: Incorrect - CRRT actually provides slower solute and water removal compared to intermittent hemodialysis.
C: Incorrect - Diffusion does occur in CRRT, as it is a key mechanism for solute removal in the process.
In summary, the key difference between CRRT and intermittent hemodialysis is the slow removal of solutes and water in CRRT, making choice D the correct answer.
