Critical Care Nursing NCLEX Questions

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.

Correct Answer: B

Rationale: Step 1: Influenza can lead to pneumonia as a complication, so getting an annual flu shot can reduce the risk of pneumonia. Step 2: Providing education on the importance of prevention aligns with discharge teaching goals. Step 3: Option A is incorrect as the pneumococcal vaccine doesn't guarantee immunity from all causes of pneumonia. Step 4: Option C is incorrect as cold or drafty places do not directly cause pneumonia. Step 5: Option D is incorrect as having pneumonia once does not confer permanent immunity.

Correct Answer: C

Rationale: Step 1: The objective is for the client to ingest at least 1000 mL of fluid between 7:00 am and 3:30 pm. Step 2: Choice C states that the client drinks 240 mL of fluid five times during the shift, totaling 1200 mL (240 mL x 5) which exceeds the required amount. Step 3: Therefore, choice C is the correct answer as it demonstrates successful achievement of the objective by ensuring the client has ingested enough fluid within the specified time frame. Step 4: Choices A, B, and D are incorrect as they do not directly address the specific objective of fluid intake set for the client. Option A focuses on intake and output, option B relates to abdominal comfort, and option D is about voiding, none of which directly address the specified objective of fluid ingestion.

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.

Correct Answer: D

Rationale: The correct answer, D, is supported by the fact that providing aggressive care to patients when nurses believe it is futile can lead to personal ethical conflicts and burnout. This is because nurses may experience moral distress when their values conflict with the care they are providing. This can result in emotional exhaustion and decreased job satisfaction, ultimately leading to burnout. Choice A is incorrect because attending funerals can be a way for nurses to process their grief and find closure, rather than creating additional stress. Choice B is incorrect because caring for dying patients can have emotional impacts on nurses, regardless of their professional approach. Choice C is incorrect because balancing care needs with personal emotional needs can be challenging and may not always be achievable.
