Nursing Elites

1. What are the primary pathophysiological mechanisms responsible for ascites in liver failure?

• A. Decreased liver enzymes.
• B. Increased hydrostatic pressure in portal circulation.
• C. High bilirubin levels.
• D. Fluid shifts due to decreased serum proteins.

Correct answer: B

Rationale: The correct answer is B: Increased hydrostatic pressure in portal circulation. Ascites in liver failure is primarily caused by fluid shifts from the intravascular space to the interstitial space due to increased hydrostatic pressure in the portal circulation. Choice A is incorrect as ascites is not caused by decreased liver enzymes. Choice C is incorrect as high bilirubin levels are not the primary mechanism for ascites in liver failure. Choice D is incorrect as fluid shifts in ascites are due to decreased serum proteins, not increased serum proteins.

2. An older client is admitted with fluid volume deficit and dehydration. Which assessment finding is the best indicator of hydration status?

• A. Urine specific gravity of 1.040.
• B. Systolic blood pressure decreases by 10 points when standing.
• C. The client denies feeling thirsty.
• D. Skin turgor exhibits tenting on the forearm.

Correct answer: A

Rationale: In the context of fluid volume deficit and dehydration, urine specific gravity of 1.040 is the best indicator of hydration status. High urine specific gravity indicates concentrated urine, suggesting dehydration. Choice B, systolic blood pressure decreasing when standing, is more indicative of orthostatic hypotension rather than hydration status. Choice C, denial of thirst, is a subjective finding and may not always reflect actual hydration status. Choice D, skin turgor exhibiting tenting on the forearm, is a sign of dehydration but may not be as accurate as urine specific gravity in assessing hydration status.

3. A client with hyperkalemia is receiving insulin and glucose. Which laboratory value should the nurse monitor closely?

• A. Monitor the client's blood glucose level.
• B. Monitor the client's sodium level.
• C. Monitor the client's calcium level.
• D. Monitor the client's potassium level.

Correct answer: D

Rationale: The correct answer is to monitor the client's potassium level. When administering insulin and glucose in hyperkalemia, the aim is to shift potassium from the bloodstream into the cells, lowering elevated levels. Therefore, monitoring potassium levels closely is essential to prevent hypokalemia or further complications. Monitoring blood glucose levels (Choice A) is important but not the priority in this scenario. Monitoring sodium (Choice B) and calcium levels (Choice C) is not directly related to the treatment of hyperkalemia with insulin and glucose.

4. An older adult client with chronic emphysema is admitted to the emergency room with acute weakness, palpitations, and vomiting. Which information is most important for the nurse to obtain during the initial interview?

• A. Recent compliance with prescribed medications.
• B. Sleep patterns during the previous few weeks.
• C. History of smoking over the past 6 months.
• D. Activity level prior to the onset of symptoms.

Correct answer: A

Rationale: The correct answer is A: Recent compliance with prescribed medications. In a client with chronic emphysema experiencing acute symptoms, it is crucial to assess medication compliance as it directly impacts the management of the condition and could contribute to the current presentation. Ensuring that the client has been taking their prescribed medications can provide vital information to guide further treatment. Choices B, C, and D, although important in a comprehensive assessment, are not as immediately crucial as assessing medication compliance in this emergency situation.

5. During the admission assessment of a 3-year-old with bacterial meningitis and hydrocephalus, which assessment finding is evidence of increased intracranial pressure (ICP)?

• A. Low blood pressure
• B. Increased respiratory rate
• C. Normal pupil reaction
• D. Sluggish and unequal pupillary responses

Correct answer: D

Rationale: Sluggish and unequal pupillary responses are indicative of increased intracranial pressure (ICP) in a child with bacterial meningitis and hydrocephalus. This finding suggests that the optic nerve is being compressed due to increased ICP, causing a delay in pupillary reactions. Such a delay is a critical sign of worsening ICP and necessitates immediate intervention. Low blood pressure and increased respiratory rate can occur in various conditions but are less specific to increased ICP than sluggish and unequal pupillary responses, which directly reflect neurological compromise.
