Nursing Elites

1. A client with deep vein thrombosis (DVT) is prescribed heparin. What lab value should the nurse monitor to assess the effectiveness of the therapy?

• A. Prothrombin time (PT).
• B. Partial thromboplastin time (PTT).
• C. International Normalized Ratio (INR).
• D. Hemoglobin and hematocrit.

Correct answer: B

Rationale: The correct answer is B: Partial thromboplastin time (PTT). PTT is the lab value used to monitor the effectiveness of heparin therapy in clients with DVT. It measures the intrinsic pathway of coagulation and is prolonged by heparin therapy. Prothrombin time (PT) and International Normalized Ratio (INR) are primarily used to monitor warfarin therapy, not heparin. Checking hemoglobin and hematocrit levels is important but does not directly assess the effectiveness of heparin therapy in DVT.

2. A 48-year-old client with chronic alcoholism is admitted to the hospital. The nurse would anticipate that the client may be deficient in which vitamins?

• A. Vitamin B and vitamin C
• B. Vitamin D and vitamin E
• C. Vitamin K and vitamin A
• D. Vitamin A and vitamin E

Correct answer: A

Rationale: The correct answer is A. Chronic alcoholism commonly leads to deficiencies in B vitamins, particularly thiamine, and vitamin C. Thiamine deficiency can result in serious neurological issues like Wernicke-Korsakoff syndrome, while vitamin C deficiency can lead to scurvy. Choices B, C, and D are incorrect because vitamin D and E deficiencies are not typically associated with chronic alcoholism.

3. A client is receiving continuous intravenous heparin for a deep vein thrombosis. Which laboratory result should the nurse monitor to ensure therapeutic heparin levels?

• A. International normalized ratio (INR)
• B. Activated partial thromboplastin time (aPTT)
• C. Hemoglobin
• D. Platelet count

Correct answer: B

Rationale: The activated partial thromboplastin time (aPTT) is the most accurate measure of heparin's therapeutic effect. Heparin increases the time it takes for blood to clot, and the aPTT helps determine whether the dose is within the desired range for anticoagulation therapy. Monitoring the INR, hemoglobin, or platelet count is not specific to assessing therapeutic heparin levels and may not reflect the anticoagulant effect of heparin.

4. A teenager presents to the emergency department with palpitations after vaping at a party. The client is anxious, fearful, and hyperventilating. Which acid-base imbalance does the nurse anticipate the client developing?

• A. Metabolic alkalosis
• B. Respiratory alkalosis
• C. Respiratory acidosis
• D. Metabolic acidosis

Correct answer: B

Rationale: The correct answer is B: Respiratory alkalosis. Hyperventilation from anxiety or fear causes an excessive loss of CO2, leading to respiratory alkalosis. This shift in pH results from the rapid, shallow breathing that reduces the level of carbon dioxide in the blood. Respiratory acidosis would occur in cases of poor ventilation or CO2 retention, while metabolic acidosis/alkalosis relates to disturbances in bicarbonate, not breathing patterns. Therefore, in this case, the client's hyperventilation due to anxiety would likely result in respiratory alkalosis, making option B the correct choice.

5. An older client with SIRS has a temperature of 101.8°F, a heart rate of 110 beats per minute, and a respiratory rate of 24 breaths per minute. Which additional finding is most important to report to the healthcare provider?

• A. Serum creatinine of 2.0 mg/dL
• B. Elevated WBC count
• C. Blood pressure of 100/60 mmHg
• D. Oxygen saturation of 95%

Correct answer: A

Rationale: A serum creatinine level of 2.0 mg/dL indicates possible acute kidney injury, which can occur during severe systemic inflammatory response syndrome (SIRS). Reporting this value promptly allows for interventions to prevent further renal damage. Elevated WBC count (choice B) is a common feature of SIRS and may not be as urgently indicative of immediate organ damage as high creatinine levels. A blood pressure of 100/60 mmHg (choice C) is relatively low but may be a typical finding in SIRS; however, renal function is critical in this context. Oxygen saturation of 95% (choice D) is within normal limits and is not as concerning as a high creatinine level in this scenario.
