Complications common to patients receiving hemodialysis for acute kidney injury include which of the following? (Select all that apply.)
- A. Hypotension
- B. Dysrhythmias
- C. Muscle cramps
- D. Hemolysis
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.

The nurse is caring for a patient who sustained a head injury and is unresponsive to painful stimuli. Which intervention is most appropriate while bathaibnirgb. ctohme/ tpesatt ient?
- A. Ask a family member to help you bathe the patient, and discuss the family structure with the family member during the procedure .
- B. Because the patient is unconscious, complete care as q uickly and quietly as possible.
- C. Inform the patient of the day and time, and what kind o f care you are providing.
- D. Turn the television on to the evening news so that you and the patient can be updated to current events.
Correct Answer: B
Rationale: The correct answer is B: Because the patient is unconscious, complete care as quickly and quietly as possible. This is the most appropriate intervention as it prioritizes the patient's comfort and minimizes unnecessary stimulation. Performing care quickly reduces the time the patient is exposed to potentially uncomfortable procedures. Being quiet also helps create a calming environment for the patient, which is important for someone who is unresponsive.
Explanation for other choices:
A: Asking a family member to help and discussing family structure is not appropriate as it can be intrusive and may not be relevant or beneficial to the patient's care.
C: Informing the patient of the day and time is unnecessary as the patient is unresponsive. Providing care is more crucial than updating the patient.
D: Turning on the television is inappropriate as it introduces unnecessary noise and distraction, which can be overwhelming for an unresponsive patient.
The nurse is caring for a patient receiving continuous norepinephrine (Levophed) IV infusion. Which patient assessment finding indicates that the infusion rate may need to be adjusted?
- A. Heart rate is 58 beats/minute.
- B. Mean arterial pressure (MAP) is 56 mm Hg.
- C. Systemic vascular resistance (SVR) is elevated.
- D. Pulmonary artery wedge pressure (PAWP) is low.
Correct Answer: B
Rationale: The correct answer is B because a low Mean Arterial Pressure (MAP) indicates inadequate perfusion, which may require adjusting the norepinephrine infusion rate to increase blood pressure. A: A heart rate of 58 beats/minute is within a normal range and may not necessarily indicate a need for adjustment. C: Elevated Systemic Vascular Resistance (SVR) may be an expected response to norepinephrine and does not necessarily indicate a need for adjustment. D: A low Pulmonary Artery Wedge Pressure (PAWP) may indicate fluid volume deficit but does not directly relate to the need for adjusting norepinephrine infusion rate.
The central venous oxygen saturation (ScvO2) is decreasing in a patient who has severe pancreatitis. To determine the possible cause of the decreased ScvO2, the nurse assesses the patient’s:
- A. Lipase.
- B. Temperature.
- C. Urinary output.
- D. Body mass index.
Correct Answer: B
Rationale: The correct answer is B: Temperature. Decreased ScvO2 in severe pancreatitis can be due to systemic inflammatory response leading to increased metabolic demand and decreased tissue oxygen delivery. Monitoring temperature helps assess for presence of infection or sepsis, which can further decrease tissue oxygenation. Lipase (A) is specific for pancreatitis diagnosis, not directly related to ScvO2. Urinary output (C) is important for assessing renal function, not directly related to ScvO2. Body mass index (D) does not provide information on tissue oxygenation status in this context.
What is the main purpose of certification for critical care n ursing?
- A. To assure the consumer that critical nurses will not make a mistake.
- B. To help prepare the critical care nurse for graduate sch ool.
- C. To assist in promoting magnet status for a facility.
- D. To validate a nurse’s knowledge of critical care nursing
Correct Answer: D
Rationale: The correct answer is D: To validate a nurse’s knowledge of critical care nursing. Certification in critical care nursing validates a nurse's expertise and knowledge in this specialized area of nursing. It demonstrates that the nurse has met certain standards and competencies in critical care practice. This certification ensures that the nurse is well-equipped to provide high-quality care to critically ill patients.
A: To assure the consumer that critical nurses will not make a mistake - This choice is incorrect because certification does not guarantee that nurses will not make mistakes. 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.
Intrapulmonary shunting refers to what outcome?
- A. Alveoli that are not perfused.
- B. Blood that is shunted from the left side of the heart to t he right and causes heart failure.
- C. Blood that is shunted from the right side of the heart to the left without oxygenation.
- D. Shunting of blood supply to only one lung.
Correct Answer: C
Rationale: Step-by-step rationale for why choice C is correct:
1. Intrapulmonary shunting refers to blood bypassing the normal oxygenation process in the lungs.
2. Choice C describes blood being shunted from the right side of the heart (deoxygenated blood) to the left side without oxygenation, leading to systemic circulation without oxygenation.
3. Choices A, B, and D do not accurately describe intrapulmonary shunting as they focus on other concepts like alveolar perfusion, heart failure, and unilateral lung blood supply, respectively.
