Critical Care Nursing NCLEX Questions Questions

Question 1 of 5

A 53-year-old, 80-kg patient is admitted to the cardiac sur gical intensive care unit after cardiac surgery with the following arterial blood gas (ABG ) levels. What is the nurse’s interpretation of these values? pH 7.4 PaCO 40 mm Hg Bicarbonate 24 mEq/L PaO 95 mm Hg O saturation 97% Respirations 20 breaths per minute

Correct Answer: C

Rationale: The correct interpretation is C: Normal ABG values. 1. pH is within the normal range of 7.35-7.45. 2. PaCO2 is 40 mm Hg, within the normal range of 35-45 mm Hg. 3. Bicarbonate is 24 mEq/L, within the normal range of 22-26 mEq/L. 4. PaO2 is 95 mm Hg, within the normal range of 80-100 mm Hg. 5. Oxygen saturation is 97%, which is normal. 6. Respirations are also within the normal range at 20 breaths per minute. Overall, all values fall within the normal range, indicating a well-maintained acid-base balance. Other choices are incorrect because there are no abnormalities that would suggest compensated metabolic acidosis, metabolic alkalosis, or respiratory acidosis based on the given ABG values.

Question 2 of 5

In assessing a patient, the nurse understands that what sym ptomology is an early sign of hypoxemia?

Correct Answer: D

Rationale: Step 1: Restlessness is an early sign of hypoxemia due to the body's response to low oxygen levels. Step 2: Restlessness occurs as the body tries to increase oxygen intake. Step 3: Other choices are incorrect because clubbing and cyanosis are late signs, while hypotension is not a specific early sign of hypoxemia.

Question 3 of 5

The removal of plasma water and some low–molecular weight particles by using a pressure or osmotic gradient is known as

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.

Question 4 of 5

A patient is transferred to the ICU from the Birth Center of the hospital in the middle of the night after experiencing complications during delivery of her baby. The patients husband is anxious and explains to the ICU nurse that he doesnt understand why his wife has been moved to the ICU. She is going to die, isnt she? he asks the nurse. What is the nurses best response?

Correct Answer: A

Rationale: The correct answer is A because it addresses the husband's concern directly by assuring him that every measure will be taken to provide the best care for his wife. This response shows empathy and provides reassurance, which is crucial in such a stressful situation. It helps to alleviate the husband's anxiety and fear by emphasizing the hospital's commitment to his wife's well-being. Explanation for why the other choices are incorrect: B: This response does not address the husband's immediate concern about his wife's well-being and may come across as dismissive. C: Offering a place to relax does not address the husband's specific question and does not provide the information he is seeking. D: Discussing health insurance is not appropriate at this moment of crisis and does not address the husband's fears about his wife's condition.

Question 5 of 5

A PaCO 2 of 48 mm Hg is associated with what outcome?

Correct Answer: B

Rationale: The correct answer is B: Hypoventilation. A PaCO2 of 48 mm Hg indicates an elevated level of carbon dioxide in the blood, which is typically seen in hypoventilation where the lungs are not effectively removing CO2. Hypoventilation leads to respiratory acidosis. Option A is incorrect because hyperventilation would decrease PaCO2 levels. Option C is incorrect as it does not directly relate to PaCO2 levels. Option D is incorrect as increased excretion of HCO3- would not directly affect PaCO2 levels.
