Nursing Elites

1. A nurse is caring for a client who has cirrhosis. Which of the following laboratory values should the nurse expect to be decreased?

• A. Bilirubin.
• B. Albumin.
• C. Ammonia.
• D. Prothrombin time.

Correct answer: B

Rationale: In clients with cirrhosis, albumin levels are typically decreased due to impaired liver function. Bilirubin levels are often increased in cirrhosis due to the liver's inability to process bilirubin efficiently. Ammonia levels may be elevated in cirrhosis due to impaired ammonia metabolism by the liver. Prothrombin time is usually prolonged in cirrhosis because the liver's ability to synthesize clotting factors is impaired.

2. Which lab value is critical for monitoring warfarin therapy?

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

Correct answer: A

Rationale: The correct answer is A: Monitor INR. INR (International Normalized Ratio) is crucial for monitoring warfarin therapy as it helps assess the therapeutic effectiveness and bleeding risks associated with the medication. INR measures the clotting tendency of blood, which is essential in determining the appropriate dosage of warfarin. Monitoring platelet count (B), sodium levels (C), or calcium levels (D) is not primarily used for assessing warfarin therapy. Platelet count is more relevant in assessing bleeding disorders, while sodium and calcium levels are typically monitored for different medical conditions unrelated to warfarin therapy.

3. Which electrolyte imbalance is commonly associated with patients on furosemide?

• A. Hypokalemia
• B. Hyponatremia
• C. Hyperkalemia
• D. Hypercalcemia

Correct answer: A

Rationale: The correct answer is A: Hypokalemia. Furosemide, a loop diuretic, can lead to potassium loss in the body, resulting in hypokalemia. This electrolyte imbalance is commonly associated with furosemide use due to its mechanism of action in the kidneys. Hyponatremia (choice B) is not typically associated with furosemide. Hyperkalemia (choice C) and hypercalcemia (choice D) are not common electrolyte imbalances seen with furosemide use.

4. A nurse is planning care for a client who has a new prescription for warfarin. Which of the following laboratory values should the nurse monitor to determine the effectiveness of the therapy?

• A. Serum calcium level
• B. Platelet count
• C. INR
• D. WBC count

Correct answer: C

Rationale: Corrected Rationale: The nurse should monitor the client's INR to determine the effectiveness of warfarin therapy. INR monitoring is crucial as it reflects the blood's ability to clot properly. Warfarin is commonly used as an anticoagulant, and maintaining the INR within the therapeutic range ensures that the client is protected from both clotting and bleeding events. Monitoring serum calcium levels, platelet count, or WBC count is not directly related to assessing the effectiveness of warfarin therapy.

5. A nurse is caring for a client who is in labor and has an external fetal monitor in place. The nurse observes late decelerations in the fetal heart rate. Which of the following findings should the nurse identify as the cause of late decelerations?

• A. Fetal head compression
• B. Uteroplacental insufficiency
• C. Umbilical cord compression
• D. Fetal hypoxia

Correct answer: B

Rationale: Late decelerations in the fetal heart rate are caused by uteroplacental insufficiency, which results from inadequate blood flow to the placenta. This leads to reduced oxygen and nutrients reaching the fetus during contractions. Choice A, fetal head compression, does not typically cause late decelerations but can result in variable decelerations. Choice C, umbilical cord compression, usually leads to variable decelerations. Choice D, fetal hypoxia, is a broad term and not the direct cause of late decelerations, which are specifically linked to uteroplacental insufficiency.
