Nursing Elites

1. A client is newly prescribed lithium for bipolar disorder. Which finding is most important to report to the healthcare provider?

• A. A serum lithium level of 1.2 mEq/L.
• B. Fine hand tremors noted after starting the medication.
• C. A blood pressure of 110/60 mmHg.
• D. A serum sodium level of 140 mEq/L.

Correct answer: B

Rationale: The correct answer is B. Fine hand tremors noted after starting lithium are an early sign of lithium toxicity. It is crucial to report this finding to the healthcare provider promptly. Adjusting the dose or monitoring serum levels more closely may be necessary to prevent further toxicity. Choice A, a serum lithium level of 1.2 mEq/L, is within the therapeutic range (0.6-1.2 mEq/L) for treating bipolar disorder. Choice C, a blood pressure of 110/60 mmHg, and Choice D, a serum sodium level of 140 mEq/L, are within normal limits and not directly related to lithium therapy or toxicity.

2. The nurse is assessing a client with rheumatoid arthritis who is taking a nonsteroidal anti-inflammatory drug (NSAID). Which laboratory value should the nurse monitor?

• A. Potassium
• B. Hemoglobin
• C. Serum creatinine
• D. White blood cell count

Correct answer: C

Rationale: When a client with rheumatoid arthritis is taking NSAIDs, the nurse should monitor serum creatinine levels. NSAIDs can potentially cause kidney damage, so monitoring creatinine levels helps assess for renal impairment. While monitoring hemoglobin, potassium, and white blood cell count may also be relevant in some cases, serum creatinine is the priority due to the risk of renal complications associated with NSAID use.

3. A client with a history of atrial fibrillation is prescribed warfarin. What is the nurse's priority teaching?

• A. Avoid eating foods high in potassium.
• B. Avoid foods high in vitamin K.
• C. Take the medication on an empty stomach.
• D. Take the medication at bedtime for best results.

Correct answer: B

Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Warfarin is an anticoagulant medication that works by interfering with vitamin K-dependent clotting factors. Therefore, consuming foods high in vitamin K can affect the medication's effectiveness. Choices A, C, and D are incorrect because: A) Warfarin is not affected by foods high in potassium; C) Warfarin should be taken with food to minimize gastrointestinal side effects; D) There is no specific requirement for taking warfarin at bedtime for best results.

4. A client in labor who received epidural anesthesia experiences a sudden drop in blood pressure. What action should the nurse take first?

• A. Administer oxygen via nasal cannula.
• B. Administer an intravenous fluid bolus.
• C. Prepare the client for an emergency cesarean section.
• D. Place the client in a lateral position.

Correct answer: D

Rationale: In a client experiencing a sudden drop in blood pressure after epidural anesthesia, the first action the nurse should take is to place the client in a lateral position. This position helps improve venous return and cardiac output by relieving aortocaval compression. Administering oxygen via nasal cannula may be necessary if the client shows signs of respiratory distress, but it is not the first priority in this situation. Administering an intravenous fluid bolus can help stabilize blood pressure, but repositioning the client takes precedence. Preparing the client for an emergency cesarean section is not indicated solely based on a sudden drop in blood pressure after epidural anesthesia; this step would be considered if other complications arise.

5. 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.
