The removal of plasma water and some low–molecular weight particles by using a pressure or osmotic gradient is known as
- A. dialysis.
- B. diffusion.
- C. clearance.
- D. ultrafiltration.
Correct Answer: D
Rationale: Ultrafiltration is the correct answer because it involves the removal of plasma water and low-molecular weight particles by using a pressure or osmotic gradient. During ultrafiltration, the pressure gradient pushes the fluid through a semipermeable membrane, separating the substances based on their molecular size. This process allows for the selective removal of unwanted substances while retaining essential components. Dialysis (choice A) involves the removal of waste products from the blood, but it does not specifically target plasma water and low-molecular weight particles. Diffusion (choice B) is the passive movement of particles from an area of higher concentration to an area of lower concentration and is not specific to the removal of plasma water. Clearance (choice C) refers to the rate at which a substance is removed from the blood and does not involve the mechanism of pressure or osmotic gradient utilized in ultrafiltration.

The nurse is caring for a patient who has an intra-aortic balloon pump in place. Which action should be included in the plan of care?
- A. Position the patient supine at all times.
- B. Avoid the use of anticoagulant medications.
- C. Measure the patient’s urinary output every hour.
- D. Provide a massive range of motion for all extremities.
Correct Answer: C
Rationale: The correct answer is C: Measure the patient’s urinary output every hour. This is crucial because monitoring urinary output is essential in assessing the patient’s renal function and the effectiveness of the intra-aortic balloon pump in improving cardiac output. Hourly measurement helps in early detection of any changes that may indicate complications.
A: Positioning the patient supine at all times is not necessary and can lead to complications.
B: Avoiding the use of anticoagulant medications is not appropriate as they are often necessary to prevent clot formation around the balloon pump.
D: Providing a massive range of motion for all extremities is not recommended for a patient with an intra-aortic balloon pump as it can dislodge the device or cause harm.
A nurse who plans care based on the patient’s gender, ethn ai bc iri bt .y co, ms /p tei sr ti tuality, and lifestyle is said to demonstrate what focus?
- A. Becoming a moral advocate.
- B. Facilitating all forms of learning.
- C. Responding to diversity.
- D. Using effective clinical judgment.
Correct Answer: C
Rationale: The correct answer is C: Responding to diversity. By considering the patient's gender, ethnicity, spirituality, and lifestyle, the nurse is focusing on responding to diversity in patient care. This approach acknowledges and respects the unique characteristics and backgrounds of individual patients, leading to more culturally competent and effective care.
Choice A: Becoming a moral advocate does not directly relate to considering diversity in patient care. It involves standing up for ethical principles and values in healthcare.
Choice B: Facilitating all forms of learning is not specific to addressing diversity in patient care. It pertains to promoting education and understanding in various learning styles.
Choice D: Using effective clinical judgment is important in nursing practice but does not specifically address the focus on diversity in patient care. It pertains to making sound decisions based on clinical knowledge and expertise.
A patient in hospice care is experiencing dyspnea. What is the most appropriate nursing intervention?
- A. Position the patient flat on their back.
- B. Administer oxygen as prescribed.
- C. Restrict fluid intake to reduce congestion.
- D. Perform chest physiotherapy to improve breathing.
Correct Answer: B
Rationale: The correct answer is B: Administer oxygen as prescribed. Dyspnea in a hospice patient often indicates respiratory distress, and administering oxygen can help improve oxygenation and alleviate breathing difficulty. Positioning the patient flat on their back (A) may worsen dyspnea due to increased pressure on the diaphragm. Restricting fluid intake (C) is not appropriate as dehydration can exacerbate respiratory distress. Chest physiotherapy (D) may not be suitable for a hospice patient experiencing dyspnea as it can be physically taxing and may not address the underlying cause effectively.
What are the diagnostic criteria for acute respiratory distress syndrome (ARDS)? (Select all that apply.)
- A. Bilateral infiltrates on chest x-ray study
- B. Decreased cardiac output
- C. PaO /FiO ratio of less than 200 2 2
- D. Pulmonary artery occlusion pressure (PAOP) of more than 18 mm Hg
Correct Answer: A
Rationale: The correct answer is A: Bilateral infiltrates on chest x-ray study. ARDS diagnosis requires bilateral infiltrates on chest x-ray, indicative of non-cardiogenic pulmonary edema. Choice B, decreased cardiac output, is not a diagnostic criterion for ARDS. Choice C, PaO2/FiO2 ratio of less than 200, is a key diagnostic criteria for ARDS, indicating severe hypoxemia. Choice D, PAOP of more than 18 mm Hg, is used to differentiate between cardiogenic and non-cardiogenic causes of pulmonary edema, but it is not a direct diagnostic criterion for ARDS.
The patient’s partner, experiencing anticipatory grieving, tells the nurse, “I don’t see any point in continuing to visit at the bedside, since it’s like I’m not even here.” What is the nurse’s best response to the partner’s statement?
- A. “You’re right, there is no awareness of anything going on now.”
- B. “Unresponsiveness doesn’t mean the sense of hearing is gone and there is a benefit from you being present.”
- C. “I’ll call you if the patient begins responding again.”
- D. “Why don’t you check to see if any other family memb er would like to visit?”
Correct Answer: B
Rationale: The correct answer is B because it acknowledges the partner's feelings while providing information that may help them cope. By stating that unresponsiveness doesn't mean the patient can't hear, the nurse highlights the importance of the partner's presence for emotional support. It encourages the partner to continue visiting, emphasizing their role in providing comfort to the patient.
Choice A is incorrect as it dismisses the partner's feelings and lacks empathy. Choice C is incorrect as it implies the nurse will only involve the partner if the patient responds, neglecting the partner's emotional needs. Choice D is incorrect as it deflects responsibility from addressing the partner's concerns and suggests involving other family members without addressing the partner's feelings directly.
