A client with a history of myocardial infarction (MI) is prescribed atorvastatin (Lipitor). Which outcome indicates that the medication is effective?
- A. Increased blood pressure.
- B. Lowered cholesterol levels.
- C. Decreased heart rate.
- D. Improved liver function.
Correct Answer: B
Rationale: The correct answer is B: Lowered cholesterol levels. Atorvastatin is a statin medication used to lower cholesterol levels, reducing the risk of further cardiovascular events in patients with a history of MI. Lowering cholesterol helps prevent plaque buildup in arteries, reducing the likelihood of another MI. Increased blood pressure (A) and decreased heart rate (C) are not direct indicators of atorvastatin's effectiveness. Improved liver function (D) may be a consideration due to potential side effects, but the primary goal of atorvastatin is to lower cholesterol levels to prevent cardiovascular events.

A client with a history of diabetes mellitus presents with confusion, sweating, and palpitations. What should the nurse do first?
- A. Check the client's blood glucose level.
- B. Administer 10 units of insulin.
- C. Give the client a high-protein snack.
- D. Measure the client's blood pressure.
Correct Answer: A
Rationale: The correct answer is A: Check the client's blood glucose level. The client's symptoms are indicative of hypoglycemia, which is a common complication in diabetes mellitus. Checking the blood glucose level will confirm the diagnosis and guide appropriate interventions. Administering insulin (B) could worsen the hypoglycemia. Giving a high-protein snack (C) may help raise blood sugar levels but should be done after confirming the diagnosis. Measuring blood pressure (D) is not the priority in this situation.
A client with severe anemia is being treated with a blood transfusion. Which assessment finding indicates a transfusion reaction?
- A. Elevated blood pressure.
- B. Fever and chills.
- C. Increased urine output.
- D. Bradycardia.
Correct Answer: B
Rationale: The correct answer is B: Fever and chills. This indicates a transfusion reaction because it is a common symptom of hemolytic reactions, where the body is reacting to incompatible blood. Elevated blood pressure (A) is not typically a sign of a transfusion reaction. Increased urine output (C) is more likely a sign of fluid overload. Bradycardia (D) is not a common symptom of a transfusion reaction. Fever and chills are classic signs of a transfusion reaction due to the body's immune response to the blood transfusion.
The healthcare professional is caring for a client with a chest tube following a thoracotomy. Which assessment finding requires immediate intervention?
- A. Continuous bubbling in the water seal chamber.
- B. Serosanguineous drainage in the collection chamber.
- C. Intermittent bubbling in the suction control chamber.
- D. Chest tube secured to the client's chest wall.
Correct Answer: A
Rationale: The correct answer is A: Continuous bubbling in the water seal chamber. Continuous bubbling in the water seal chamber indicates an air leak in the system, which can lead to pneumothorax or compromised lung function. Immediate intervention is required to prevent complications. Serosanguineous drainage in the collection chamber (B) is expected after thoracotomy. Intermittent bubbling in the suction control chamber (C) is normal and indicates proper suction function. Chest tube secured to the client's chest wall (D) is essential for stability and should not require immediate intervention.
During the initial assessment of a client with a history of substance abuse admitted for detoxification, which intervention is most important?
- A. Obtain a detailed substance use history.
- B. Establish a trusting nurse-client relationship.
- C. Evaluate the client's physical health status.
- D. Determine the client's readiness for change.
Correct Answer: C
Rationale: The correct answer is C: Evaluate the client's physical health status. This is crucial during detoxification as substance withdrawal can lead to serious physical health complications such as seizures or cardiac issues. Assessing physical health status allows for prompt intervention if needed. Obtaining a detailed substance use history (A) can provide valuable information but is not immediate priority during initial assessment. Establishing a trusting nurse-client relationship (B) is important but ensuring physical safety comes first. Determining client's readiness for change (D) is important for long-term treatment planning but not as urgent as assessing physical health status.
What action should the nurse take to prevent tracheal tissue damage in a client with a tracheostomy?
- A. Secure the tracheostomy ties firmly.
- B. Change the tracheostomy tube daily.
- C. Use the minimal leak technique when inflating the cuff.
- D. Clean the stoma with hydrogen peroxide.
Correct Answer: C
Rationale: The correct action to prevent tracheal tissue damage in a client with a tracheostomy is to use the minimal leak technique when inflating the cuff (Choice C). This technique helps maintain proper cuff pressure, preventing excessive pressure on the tracheal tissue. Securing the tracheostomy ties firmly (Choice A) may cause pressure ulcers on the neck. Changing the tracheostomy tube daily (Choice B) is unnecessary and may introduce infection. Cleaning the stoma with hydrogen peroxide (Choice D) can be too harsh and damaging to the delicate tracheal tissue.
