Nursing Elites

1. A client with heart failure is receiving intravenous furosemide (Lasix). Which assessment finding indicates that the medication is having the desired effect?

• A. Decreased peripheral edema.
• B. Elevated blood pressure.
• C. Increased heart rate.
• D. Decreased urine output.

Correct answer: A

Rationale: The correct answer is A: 'Decreased peripheral edema.' In a client with heart failure receiving furosemide, decreased peripheral edema indicates that the medication is effectively reducing fluid overload. Furosemide is a diuretic that helps the body eliminate excess fluid and salt through increased urine output, leading to a reduction in peripheral edema, which is a common symptom of heart failure. Monitoring and recognizing this improvement in edema are crucial in managing heart failure effectively.

2. A patient with hyperlipidemia is prescribed atorvastatin. What lab test should be monitored periodically to assess for adverse effects?

• A. Liver function tests
• B. Complete blood count
• C. Blood glucose levels
• D. Serum potassium

Correct answer: A

Rationale: The correct answer is A: Liver function tests. Patients on atorvastatin should have their liver function tests monitored periodically to detect any potential liver damage. Atorvastatin, a statin medication used to lower cholesterol levels, can rarely cause liver enzyme abnormalities, so regular monitoring is essential to identify any adverse effects early on. Monitoring the complete blood count (choice B), blood glucose levels (choice C), or serum potassium (choice D) is not typically required specifically for atorvastatin therapy. While these tests may be important for other conditions or medications, liver function tests are the most relevant for monitoring the adverse effects of atorvastatin.

3. A patient with a diagnosis of deep vein thrombosis (DVT) is receiving heparin therapy. Which laboratory test should the nurse monitor to evaluate the effectiveness of the heparin therapy?

• A. Prothrombin time (PT)
• B. Partial thromboplastin time (PTT)
• C. Bleeding time
• D. Platelet count

Correct answer: B

Rationale: The correct answer is B: Partial thromboplastin time (PTT). Heparin affects the intrinsic pathway of the coagulation cascade, which is reflected by changes in the PTT. Monitoring the PTT helps ensure that the patient's blood is within the desired therapeutic range and prevents complications related to clotting or bleeding. Prothrombin time (PT) primarily assesses the extrinsic pathway and is not as sensitive to heparin therapy. Bleeding time and platelet count are not specific tests for monitoring the effectiveness of heparin therapy in DVT.

4. A patient with heart failure is prescribed digoxin. What is the most important instruction the nurse should provide?

• A. Take an extra dose if you miss one.
• B. Avoid high-potassium foods.
• C. Report any visual disturbances.
• D. Stop taking the medication if your pulse is normal.

Correct answer: C

Rationale: The correct answer is C: 'Report any visual disturbances.' Patients taking digoxin should be instructed to report any visual disturbances, as this can be a sign of digoxin toxicity. Visual disturbances like changes in color vision, blurred vision, or seeing halos around lights can indicate an overdose of digoxin. Choices A, B, and D are incorrect. Instructing a patient to take an extra dose if they miss one can lead to overdose. Avoiding high-potassium foods is important for patients on potassium-sparing diuretics, not digoxin. Stopping the medication if the pulse is normal is incorrect, as the pulse rate alone is not an indicator of digoxin effectiveness or toxicity.

5. What action should the nurse take for a patient admitted with diabetic ketoacidosis exhibiting rapid, deep respirations?

• A. Administer the prescribed PRN lorazepam (Ativan).
• B. Start the prescribed PRN oxygen at 2 to 4 L/min.
• C. Administer the prescribed normal saline bolus and insulin.
• D. Encourage the patient to practice guided imagery for relaxation.

Correct answer: C

Rationale: The correct action for a patient with diabetic ketoacidosis and rapid, deep (Kussmaul) respirations is to administer a normal saline bolus and insulin. The rapid, deep respirations indicate a metabolic acidosis, which requires correction with a saline bolus to prevent hypovolemia and insulin to facilitate glucose re-entry into cells. Oxygen therapy is not necessary since the increased respiratory rate is compensatory and not due to hypoxemia. Encouraging relaxation techniques or administering lorazepam are inappropriate as they can worsen the acidosis by suppressing the compensatory respiratory effort.
