Nursing Elites

1. A nurse is caring for a client who is receiving warfarin therapy. Which of the following laboratory results indicates the need for an increase in the dose of warfarin?

• A. PT 28 seconds
• B. INR 1.2
• C. aPTT 40 seconds
• D. Fibrinogen 350 mg/dL

Correct answer: B

Rationale: An INR of 1.2 is below the therapeutic range for a client on warfarin, indicating inadequate anticoagulation. Therefore, the client would require an increase in the dose of warfarin to achieve the desired therapeutic effect. Choices A, C, and D are not indicative of the need for a dose increase in warfarin therapy. PT of 28 seconds is within the therapeutic range, aPTT of 40 seconds is also within the normal range, and fibrinogen level of 350 mg/dL does not provide information about the anticoagulant effect of warfarin.

2. A nurse in a pediatric clinic is reviewing the laboratory test results of a school-age child. Which of the following findings should the nurse report to the provider?

• A. Hgb 12.5 g/dL.
• B. Platelets 250,000/mm³.
• C. Hct 40%.
• D. WBC 14,000/mm³.

Correct answer: D

Rationale: The correct answer is D. A WBC count of 14,000/mm³ is elevated, indicating a potential infection or inflammation, and should be reported to the provider for further evaluation and management. Choices A, B, and C are within normal ranges and do not require immediate reporting as they indicate normal hemoglobin, platelet count, and hematocrit levels for a school-age child.

3. A client has a central venous catheter. Which of the following actions should be taken to prevent an air embolism?

• A. Keep the catheter clamped when not in use
• B. Have the client perform the Valsalva maneuver while the catheter is removed
• C. Use a non-coring needle to access the catheter
• D. Flush the catheter with 0.9% sodium chloride every 24 hours

Correct answer: B

Rationale: The correct action to prevent an air embolism in a client with a central venous catheter is to have the client perform the Valsalva maneuver while the catheter is removed. This maneuver helps to close the airway and prevent air from entering the bloodstream. Keeping the catheter clamped at all times (Choice A) is not necessary and may lead to clot formation. Using a non-coring needle (Choice C) is important for accessing the catheter but does not specifically prevent air embolism. Flushing the catheter with 0.9% sodium chloride (Choice D) helps maintain patency but does not directly prevent air embolism.

4. A nurse is teaching a client about the physiological changes that occur with aging. Which of the following findings should the nurse expect?

• A. Decreased sense of taste
• B. Decreased blood pressure
• C. Increased gastric secretions
• D. Increased accommodation to near vision

Correct answer: A

Rationale: The correct answer is A: Decreased sense of taste. As individuals age, they may experience a decrease in their sense of taste due to changes in taste buds and a decrease in saliva production. This can lead to a reduced ability to taste flavors or distinguish between different tastes. Choices B, C, and D are incorrect. Decreased blood pressure is not a consistent physiological change with aging; instead, blood pressure may increase or remain stable. Gastric secretions tend to decrease with age, leading to issues like decreased absorption of certain nutrients. Accommodation to near vision typically decreases with age, causing a condition known as presbyopia, where individuals have difficulty focusing on close objects.

5. A nurse is caring for a client who has right-sided heart failure. Which of the following findings should the nurse expect?

• A. Peripheral edema.
• B. JVD.
• C. Crackles in the lungs.
• D. Hypotension.

Correct answer: B

Rationale: The correct answer is B: JVD. Jugular venous distention (JVD) is a common finding in right-sided heart failure due to fluid overload. This occurs because the right side of the heart is unable to effectively pump blood, leading to congestion and increased venous pressure, which is manifested as JVD. Choices A, C, and D are incorrect. Peripheral edema (choice A) is more commonly associated with left-sided heart failure. Crackles in the lungs (choice C) are indicative of pulmonary edema, often seen in left-sided heart failure. Hypotension (choice D) is not typically seen in right-sided heart failure, as it is more commonly associated with conditions like shock or severe dehydration.
