Noninvasive diagnostic procedures used to determine kidney function include which of the following? (Select all that apply.)
- A. Kidney, ureter, bladder (KUB) x-ray
- B. Renal ultrasound
- C. Magnetic resonance imaging (MRI)
- D. Intravenous pyelography (IVP)
Correct Answer: A
Rationale: The correct answer is A: Kidney, ureter, bladder (KUB) x-ray. This procedure is noninvasive and commonly used to assess kidney function by visualizing the size, shape, and position of the kidneys. Renal ultrasound is also noninvasive and can provide detailed images of the kidneys. However, MRI and IVP are more invasive procedures that involve the use of contrast agents and are not typically used solely for diagnostic purposes to assess kidney function. Overall, KUB x-ray and renal ultrasound are the preferred noninvasive options for evaluating kidney function.

Which of the following are physiological effects of positive end-expiratory pressure (PEEP) used in the treatment of acute respiratory distress syndrom e (ARDS)? (Select all that apply.)
- A. Increase functional residual capacity
- B. Prevent collapse of unstable alveoli
- C. Improve arterial oxygenation
- D. Open collapsed alveoli
Correct Answer: A
Rationale: The correct answer is A: Increase functional residual capacity. Positive end-expiratory pressure (PEEP) helps increase the functional residual capacity by keeping the alveoli open at the end of expiration. This prevents alveolar collapse, improves ventilation-perfusion matching, and enhances oxygenation.
B: Prevent collapse of unstable alveoli - This is incorrect because PEEP actually helps prevent the collapse of all alveoli, not just unstable ones.
C: Improve arterial oxygenation - This is partially correct, but the primary mechanism through which PEEP improves oxygenation is by increasing functional residual capacity.
D: Open collapsed alveoli - This is incorrect because PEEP helps prevent alveolar collapse rather than actively opening already collapsed alveoli.
As part of the Synergy Model, the nurse has identified a patient characteristic of resiliency. What patient behavior demonstrates resiliency?
- A. Dysfunctional grieving behaviors after receiving bad news
- B. Developing a list of questions for the physician
- C. Denial of any possible negative outcomes for a procedure
- D. Assigning blame to others for undesired outcomes of illness
Correct Answer: B
Rationale: The correct answer is B because developing a list of questions for the physician shows active engagement in their healthcare, seeking information, and taking control of their situation, which are characteristics of resiliency. This behavior indicates the patient's willingness to understand and cope with their health condition. Choices A, C, and D are incorrect as they demonstrate maladaptive coping mechanisms such as dysfunctional grieving, denial, and blame assignment, which are not indicative of resiliency. Resiliency involves adaptability, problem-solving, and seeking support, which are better exemplified by choice B.
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.
Which nursing strategies help the patient to feel safe in the critical care setting? (Select all that apply.)
- A. Allow family members to remain at the bedside.
- B. Be sure to consult with the charge nurse before making any patient care decisions.
- C. Provide informal conversation by discussing your planasb ifrbo.rc oamf/tteesrt work.
- D. Explain how to communicate for assistance.
Correct Answer: A
Rationale: The correct answer is A because allowing family members to remain at the bedside can provide emotional support and comfort to the patient, helping them feel safe in the critical care setting. Family presence can also facilitate communication and understanding between the healthcare team and the patient.
Choice B is incorrect because consulting with the charge nurse before making patient care decisions may not directly contribute to the patient feeling safe.
Choice C is incorrect because providing informal conversation about work-related topics may not address the patient's need for safety and security in the critical care setting.
Choice D is incorrect because explaining how to communicate for assistance is important for patient care but may not directly contribute to the patient's sense of safety in the critical care setting.
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.
