Free Acute Care Nurse Practitioner MCQ Question and Answers — Questions and Answers
Question 1: The Cerebral Spinal Fluid's (CSF) major purpose is to...
- providing mechanical protection to the brain and the spinal cord. (Correct answer)
- acting as a buffer for the brain and the spinal cord and absorbing shock (Correct answer)
- establishing a connection between the brain and the spinal cord.
- none of the above
Correct answer: providing mechanical protection to the brain and the spinal cord.
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?
- Monitor the kidney function on a daily basis
- Make sure that no further exposure to the nephrotoxic agent is happening (Correct answer)
- Stop the patient's medications for diabetes
- None of the above
Correct answer: Make sure that no further exposure to the nephrotoxic agent is happening
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?
- Hypertension
- Hypercalcemia
- Hyperkalemia (Correct answer)
- None of the above
Correct answer: Hyperkalemia
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.
- Acetaminophen (Tylenol) overdose
- Biliary atresia
- Autoimmune hepatitis
- All of the above (Correct answer)
Correct answer: All of the above
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.
- Antipyretics
- Analgesics
- Statins
- Anticholinergics (Correct answer)
Correct answer: Anticholinergics
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.
Question 6: Please indicate which of the following is not an illustration of a task that a nurse practitioner may delegate to a nursing assistant.
- Assisting a patient's ambulation
- Assessing a patient's signs and symptoms (Correct answer)
- Demonstrating a patient how to use a Glucose meter (Correct answer)
- All of the above are appropriate tasks to be assigned to a nursing assistant
Correct answer: Assessing a patient's signs and symptoms
Assessing a patient's signs and symptoms requires clinical judgment, critical thinking, and a comprehensive understanding of pathophysiology, which are skills within the scope of a licensed nurse (NP or RN). Nursing assistants (NAs) are trained for basic care tasks and cannot perform assessments or provide initial patient education that demands professional nursing judgment. Therefore, assessing a patient's condition is not an appropriate task for delegation to an NA.
Question 7: Which of the following measures renal physiology and functions the most correctly?
- BUN (blood urea nitrogen)
- Either of the above, they are equally accurate
- GFR (glomerular filtration rate) (Correct answer)
- None of the above
Correct answer: GFR (glomerular filtration rate)
The Glomerular Filtration Rate (GFR) is considered the most accurate measure of overall kidney function because it directly quantifies the filtering capacity of the kidneys. It indicates how much blood is filtered by the glomeruli per minute, reflecting the efficiency of waste removal. While BUN (blood urea nitrogen) is also used, it can be influenced by non-renal factors, making GFR a more specific and reliable indicator of renal health.
