Nursing Elites

1. A healthcare professional is reviewing the medical record of a client scheduled for a CT scan with contrast media. The healthcare professional should identify which of the following findings as a contraindication to the procedure?

• A. White blood cell count of 6,000/mm³
• B. Urine specific gravity of 1.025
• C. History of asthma
• D. History of allergy to shellfish

Correct answer: D

Rationale: The correct answer is D, a history of allergy to shellfish. A known allergy to shellfish is a contraindication for the use of contrast media in a CT scan due to the potential risk of an allergic reaction, which could be severe and life-threatening. Choices A, B, and C are not contraindications to the procedure. A normal white blood cell count, urine specific gravity within the normal range, and a history of asthma do not typically interfere with the administration of contrast media for a CT scan.

2. A nurse is caring for a client who has a pulmonary embolism. The nurse should identify which finding as an indication of effective treatment?

• A. A chest x-ray reveals increased density in all lung fields.
• B. The client reports feeling less anxious.
• C. Diminished breath sounds are auscultated bilaterally.
• D. ABG results include a pH of 7.48, PaO2 77 mm Hg, and PaCO2 47 mm Hg.

Correct answer: B

Rationale: The correct answer is B. The client reporting feeling less anxious is a positive indication of effective treatment for a pulmonary embolism. This suggests that the client's condition is improving psychologically. Option A is incorrect because increased density in all lung fields on a chest x-ray may indicate unresolved issues related to the embolism. Option C is incorrect as diminished breath sounds bilaterally suggest a complication or worsening of the condition. Option D is incorrect as ABG results within normal range do not necessarily indicate effective treatment for a pulmonary embolism, as other complications may still be present.

3. A client has a new prescription for furosemide. Which of the following instructions should the nurse include?

• A. Avoid consuming dairy products.
• B. Increase your intake of potassium-rich foods.
• C. Limit fluid intake to prevent dehydration.
• D. Take the medication at bedtime.

Correct answer: B

Rationale: The correct answer is to instruct the client to increase their intake of potassium-rich foods when taking furosemide. Furosemide is a loop diuretic that can cause potassium loss, so consuming potassium-rich foods like bananas and oranges can help maintain adequate potassium levels. Choice A is incorrect because there is no need to avoid consuming dairy products. Choice C is incorrect because while fluid intake may need to be monitored, the general instruction is not to limit fluids to prevent dehydration. Choice D is incorrect because furosemide is usually best taken during the day to avoid disrupting sleep with frequent urination.

4. How should fluid overload in a patient with heart failure be managed?

• A. Administer diuretics
• B. Increase fluid intake
• C. Provide oral fluids
• D. Provide chest physiotherapy

Correct answer: A

Rationale: Administering diuretics is the appropriate management for fluid overload in a patient with heart failure. Diuretics help to reduce fluid retention by increasing urine output, thereby alleviating the fluid overload. Choices B, C, and D are incorrect. Increasing fluid intake would worsen the condition by adding more fluid to an already overloaded system. Providing oral fluids is not specific enough to address the excess fluid in the body, and chest physiotherapy is not indicated for managing fluid overload in heart failure patients.

5. Which lab value is critical for a patient on heparin therapy?

• A. Monitor aPTT
• B. Monitor INR
• C. Monitor platelet count
• D. Monitor sodium levels

Correct answer: A

Rationale: The correct answer is to monitor aPTT. Activated Partial Thromboplastin Time (aPTT) is crucial for patients on heparin therapy as it helps determine the clotting ability of the blood. By monitoring aPTT, healthcare providers can adjust the dosage of heparin to maintain therapeutic levels and prevent bleeding complications. Monitoring INR is more commonly associated with warfarin therapy, not heparin. Monitoring platelet count is important for assessing the risk of bleeding or clotting disorders but is not specific to heparin therapy. Monitoring sodium levels is not directly related to assessing the effectiveness or safety of heparin therapy.
