Nursing Elites

1. A nurse is assessing a client who has a history of atrial fibrillation and is receiving warfarin. Which of the following laboratory values should the nurse monitor to determine the effectiveness of the warfarin?

• A. Platelet count
• B. International normalized ratio (INR)
• C. Bleeding time
• D. Partial thromboplastin time (PTT)

Correct answer: B

Rationale: The correct answer is B: International normalized ratio (INR). The INR is used to monitor the effectiveness of warfarin therapy. A higher INR indicates a longer time it takes for the blood to clot, which is desirable in patients receiving warfarin to prevent blood clots. Platelet count (Choice A) assesses the number of platelets in the blood and is not directly related to warfarin therapy. Bleeding time (Choice C) evaluates the time it takes for a person to stop bleeding after a standardized wound, but it is not specific to monitoring warfarin effectiveness. Partial thromboplastin time (PTT) (Choice D) is more commonly used to monitor heparin therapy, not warfarin.

2. A nurse is caring for a client prescribed levetiracetam. Which of the following should the nurse monitor?

• A. Liver function
• B. Blood glucose levels
• C. Serum creatinine
• D. Blood pressure

Correct answer: C

Rationale: The correct answer is C: Serum creatinine. Levetiracetam requires monitoring of renal function, specifically serum creatinine levels, as it is primarily eliminated by the kidneys. Monitoring liver function (Choice A) is not necessary for levetiracetam. Blood glucose levels (Choice B) are typically not affected by levetiracetam. While monitoring blood pressure (Choice D) is important in general patient care, it is not specifically required for clients prescribed levetiracetam.

3. A nurse is assessing a client who has diabetic ketoacidosis (DKA). Which of the following laboratory findings should the nurse expect?

• A. Blood glucose 120 mg/dL
• B. pH 7.32
• C. HCO3 25 mEq/L
• D. PaCO2 48 mm Hg

Correct answer: B

Rationale: The correct answer is B. A pH of 7.32 indicates metabolic acidosis, which is a hallmark of diabetic ketoacidosis (DKA). In DKA, blood glucose levels are typically elevated, bicarbonate levels are often low, and there is a compensatory respiratory response leading to a decrease in PaCO2. Option A is incorrect because a blood glucose level of 120 mg/dL is within the normal range and not indicative of DKA. Option C is incorrect because an HCO3 level of 25 mEq/L is not typically seen in DKA where bicarbonate levels are usually lower. Option D is incorrect because a PaCO2 of 48 mm Hg would not be expected in DKA; it would typically be lower due to compensatory respiratory alkalosis.

4. A healthcare professional is preparing to administer ceftriaxone. Which of the following actions should the healthcare professional take?

• A. Reconstitute the medication with normal saline
• B. Reconstitute the medication with sterile water
• C. Administer the medication over 30 minutes
• D. Monitor for signs of toxicity

Correct answer: B

Rationale: Correct Answer: B. Ceftriaxone should be reconstituted with sterile water, not saline. Reconstituting it with normal saline can result in a chemical interaction and precipitation of the drug. Administering the medication over 30 minutes (choice C) is not necessary as ceftriaxone is usually given as an intravenous bolus or drip over a shorter period. Monitoring for signs of toxicity (choice D) is important but not the immediate action required for preparing the medication. The priority is to ensure proper reconstitution with the appropriate solvent, which is sterile water.

5. A home health nurse is providing teaching to a family of a client who has seizure manifestations as a result of an inoperable brain tumor. What intervention should the nurse include in the teaching?

• A. Administer antiseizure medications promptly.
• B. Use oral airway devices during seizures.
• C. Pad the side rails of the bed.
• D. Apply restraints during the seizure to prevent injury.

Correct answer: C

Rationale: The correct intervention the nurse should include in the teaching is to pad the side rails of the bed. By padding the side rails, the nurse can help prevent injury if the patient experiences a seizure. Administering antiseizure medications promptly (Choice A) is typically the responsibility of a healthcare provider or according to a prescribed schedule. Using oral airway devices during seizures (Choice B) can pose risks and should be managed by healthcare professionals. Applying restraints during a seizure (Choice D) is not recommended as it can lead to further injury and complications.
