Slow continuous ultrafiltration is also known as isolated ultrafiltration and is used to
- A. remove plasma water in cases of volume overload.
- B. remove fluids and solutes through the process of convection.
- C. remove plasma water and solutes by adding dialysate.
- D. combine ultrafiltration, convection, and dialysis.
Correct Answer: A
Rationale: The correct answer is A because slow continuous ultrafiltration removes excess plasma water in cases of volume overload by applying a pressure gradient across a semipermeable membrane. This process helps to achieve fluid balance without removing solutes.
Choice B is incorrect because convection is not the primary mechanism of slow continuous ultrafiltration.
Choice C is incorrect as dialysate is not added in slow continuous ultrafiltration.
Choice D is incorrect as slow continuous ultrafiltration does not combine all three processes of ultrafiltration, convection, and dialysis.

A Muslim patient has been admitted to the critical care unit with complications after childbirth. Based on the Synergy Model, which nurse would be the most inappropriate to assign to care for this patient?
- A. New graduate female nurse
- B. Most experienced female nurse
- C. New graduate male nurse
- D. Female nurse with postpartum experience
Correct Answer: C
Rationale: Step-by-step rationale:
1. The Synergy Model emphasizes matching nurse competencies with patient needs.
2. A male nurse may not be culturally appropriate for a Muslim female patient due to religious beliefs.
3. Gender segregation is important in Islamic culture, especially concerning intimate care.
4. Therefore, assigning a new graduate male nurse to care for a Muslim female patient in critical condition is the most inappropriate choice.
Summary:
- Choice A is incorrect because being a new graduate does not impact cultural competence.
- Choice B is incorrect as experience does not necessarily make a nurse the best fit for a specific patient.
- Choice D is incorrect as postpartum experience is relevant, but cultural considerations are more critical in this scenario.
The nurse caring for a mechanically ventilated patient note s the high pressure alarm sounding but cannot quickly identify the cause of the alarm. The nurasbeir bn.cootme/ste stht e patient’s oxygen saturation is decreasing and heart rate and respiratory rate are increasing. What is the nurse’s priority action?
- A. Ask the respiratory therapist to get a new ventilator
- B. Call the rapid response team to assess the patient
- C. Continue to find the cause of the alarm and fix it
- D. Manually ventilate the patient while calling for a respi ratory therapist
Correct Answer: B
Rationale: The correct answer is B. The nurse's priority is to ensure the patient's safety and well-being. Calling the rapid response team will allow for immediate assessment by a team of healthcare professionals to address the deteriorating condition. This step takes precedence over troubleshooting the ventilator or manually ventilating the patient. Asking for a new ventilator (A) or manually ventilating the patient (D) does not address the urgent need for a comprehensive assessment and intervention. Continuing to troubleshoot the alarm (C) can delay critical interventions needed for the patient's worsening condition. Thus, calling the rapid response team is the most appropriate action to address the escalating clinical situation promptly.
The nurse is preparing to administer atropine, an anticholinergic, to a client scheduled for a cholecystectomy. The client asks the nurse to explain the reason for the prescribed medication. What response is best for the nurse to provide?
- A. Provide a more rapid induction of anesthesia.
- B. Induce relaxation before induction of anesthesia.
- C. Decrease the risk of bradycardia during surgery.
- D. Minimize the amount of analgesia needed postoperatively.
Correct Answer: C
Rationale: The correct answer is C: Decrease the risk of bradycardia during surgery.
Rationale:
1. Atropine is an anticholinergic medication that works by blocking the parasympathetic nervous system.
2. During surgery, the parasympathetic stimulation can lead to bradycardia (slow heart rate).
3. By administering atropine, the nurse can counteract the bradycardic effects and maintain a normal heart rate during the procedure.
4. Options A, B, and D are incorrect as atropine is not used for inducing anesthesia, relaxation, or minimizing postoperative analgesia.
A patient is admitted to the emergency department (ED) after falling through the ice while ice skating. Which assessment will the nurse obtain first?
- A. Heart rate.
- B. Breath sounds.
- C. Body temperature.
- D. Level of consciousness.
Correct Answer: C
Rationale: The correct answer is C: Body temperature. In a patient who has fallen through the ice, hypothermia is a major concern due to exposure to cold water. Assessing body temperature first is crucial to determine the severity of hypothermia and guide immediate interventions. Heart rate, breath sounds, and level of consciousness can be affected by hypothermia but are secondary assessments. Assessing body temperature is the priority to address the most life-threatening issue first.
Many critically ill patients experience anxiety. The nurse can reduce anxiety with which approach?
- A. Asking family members to limit their visitation to 2-hour periods in morning, afternoon, and evening. You know that this is the best approach to ensure uninterrupted rest time for the patient. Tell the patient, “Your family is in the waiting room. They will be permitted to come in at 2:0 0 PM after you take a short nap.”
- B. Explaining the unit routine. “Assessments are done every 4 hours; patients are bathed on the night shift around 5:00 AM; family memabbierbr.sc oamr/ete spt ermitted to visit you after the physicians make their morning rounds. They can spend the day. Lights are out every night at 10:00 PM.”
- C. Stating, “It’s time to turn you. I am going to ask another nurse to come in and help me. We will turn you to your left side. During the turn , I’m going to inspect the skin on your back and rub some lotion on your back. T his should help to make you feel better.”
- D. Suctioning the endotracheal tube immediately when thaeb iprba.ctoiemn/tte sst tarts to cough. Sharing, “Your tube needs suctioned; you should feel better after I’m done.”
Correct Answer: C
Rationale: The correct answer is C because it addresses the patient's anxiety by providing clear communication and involving the patient in the care process. By explaining the turning procedure, inspecting the skin, and providing comfort through lotion application, the nurse establishes trust and promotes a sense of control for the patient. This approach helps alleviate anxiety by keeping the patient informed and engaged in their care.
Choice A is incorrect because limiting family visitation may not directly address the patient's anxiety. Choice B is incorrect as it focuses on routine information rather than directly addressing the patient's anxiety. Choice D is incorrect because suctioning the endotracheal tube may cause discomfort and does not address the underlying anxiety issue.
