Free Acute Care Nurse Practitioner MCQ Question and Answers

Question 1

The Cerebral Spinal Fluid's (CSF) major purpose is to...

Accepted Answer

providing mechanical protection to the brain and the spinal cord.

Answer

The primary purposes of cerebrospinal fluid (CSF) are to provide mechanical protection to the brain and spinal cord, acting as a cushion against physical trauma. It functions as a buffer, absorbing shock and distributing forces evenly across the delicate neural tissues. While CSF also plays roles in nutrient transport and waste removal, its major protective functions are mechanical support and shock absorption.

Question 2

A nephrotoxic substance most likely contributed to a patient's acute tubular necrosis. What would the NP's first course of action be?

Accepted Answer

Make sure that no further exposure to the nephrotoxic agent is happening

Answer

Acute tubular necrosis (ATN) caused by a nephrotoxic substance requires immediate removal of the offending agent to prevent further kidney damage. While monitoring kidney function is important, stopping the exposure directly addresses the root cause and is the most critical first step. This intervention aims to halt the progression of injury and allow for potential renal recovery.

Question 3

Shortness of breath, severe weariness, and an irregular heartbeat are among a collection of symptoms that have suddenly appeared in a patient with end-stage renal disease. What is most likely the root of these symptoms?

Accepted Answer

Hyperkalemia

Answer

Patients with end-stage renal disease (ESRD) have impaired kidney function, leading to an inability to excrete potassium effectively, resulting in hyperkalemia. High potassium levels can cause life-threatening cardiac arrhythmias, manifesting as an irregular heartbeat, and also contribute to severe weariness and shortness of breath. These symptoms in an ESRD patient are highly indicative of hyperkalemia, a medical emergency.

Question 4

Please indicate which of the following circumstances increases the risk of liver failure.

Accepted Answer

All of the above

Answer

All the listed circumstances significantly increase the risk of liver failure. Acetaminophen overdose is a common cause of acute liver failure due to its hepatotoxic metabolites. Biliary atresia is a congenital condition causing bile duct obstruction and progressive liver damage, while autoimmune hepatitis involves the immune system attacking liver cells, leading to chronic inflammation and potential failure. Therefore, all options contribute to liver failure risk.

Question 5

Pancreatic juice is being secreted too much in a patient with acute pancreatitis. Please specify which drug class is most likely to reduce this symptom.

Accepted Answer

Anticholinergics

Answer

Anticholinergic drugs reduce the secretion of pancreatic juice by blocking the action of acetylcholine, a neurotransmitter that stimulates pancreatic exocrine function. By inhibiting this stimulation, anticholinergics help to decrease the excessive enzyme and fluid output from the pancreas. This mechanism can alleviate symptoms and reduce the severity of acute pancreatitis by 'resting' the inflamed organ.
