Nursing Elites

1. A client is admitted with deep vein thrombosis (DVT) and is receiving heparin therapy. What is the most important laboratory value to monitor during heparin therapy?

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

Correct answer: C

Rationale: The activated partial thromboplastin time (aPTT) is the most important laboratory value to monitor during heparin therapy. It measures the intrinsic pathway of coagulation and is used to assess the effectiveness of heparin as an anticoagulant. Keeping the aPTT within the therapeutic range is crucial to prevent complications such as bleeding or clot formation. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor warfarin therapy, not heparin. Platelet count is important to assess for thrombocytopenia, a potential side effect of heparin, but it is not the primary laboratory value to monitor the effectiveness of heparin therapy.

2. The client is being taught about precautions with Coumadin therapy. The client should be instructed to avoid which over-the-counter medication?

• A. Non-steroidal anti-inflammatory drugs
• B. Cough medicines containing guaifenesin
• C. Histamine blockers
• D. Laxatives containing magnesium salts

Correct answer: A

Rationale: The correct answer is A: Non-steroidal anti-inflammatory drugs (NSAIDs). NSAIDs can increase the risk of bleeding in clients taking Coumadin, which is an anticoagulant medication. Avoiding NSAIDs helps prevent potentially dangerous interactions with Coumadin. Choices B, C, and D are incorrect. Cough medicines with guaifenesin, histamine blockers, and laxatives containing magnesium salts do not typically have significant interactions with Coumadin therapy. Therefore, they are not the over-the-counter medications that the client needs to avoid while on Coumadin.

3. After administering a proton pump inhibitor, which action should the nurse take to evaluate the effectiveness of the medication?

• A. Monitor gastrointestinal pain
• B. Ask the client about pain levels
• C. Check the client's vital signs
• D. Assess for signs of bleeding

Correct answer: B

Rationale: The correct answer is to ask the client about pain levels. Proton pump inhibitors (PPIs) work by reducing stomach acid to alleviate gastrointestinal pain. By inquiring about the client's pain experience, the nurse can directly assess the effectiveness of the medication. Monitoring bowel movements (Choice A) is not directly related to evaluating the effectiveness of a PPI. Checking vital signs (Choice C) may not reflect the medication's effectiveness in reducing stomach acid. Assessing for signs of bleeding (Choice D) is important but not the most direct way to evaluate the effectiveness of a PPI.

4. A client who has been prescribed multiple antihypertensive medications experiences syncope and has a blood pressure of 70/40. What is the rationale for the nurse to hold the next scheduled antihypertensive dose?

• A. Increased urinary clearance of the medications has produced diuresis, lowering the blood pressure.
• B. The antagonistic interaction of the medications has reduced their effectiveness.
• C. The synergistic effect of the medications has resulted in drug toxicity, causing hypotension.
• D. The additive effect of the medications has lowered the blood pressure too much.

Correct answer: D

Rationale: The additive effect of multiple antihypertensive medications can cause hypotension, leading to dangerously low blood pressure. In this scenario, the client experiencing syncope with a blood pressure of 70/40 indicates severe hypotension, likely due to the combined action of the antihypertensive medications. Holding the next scheduled dose is essential to prevent further lowering of blood pressure and potential complications. Choices A, B, and C provide inaccurate explanations and do not align with the client's presentation and the need to manage hypotension caused by the additive effect of the medications.

5. The nurse is caring for a client receiving a blood transfusion who develops urticaria half an hour after the transfusion has begun. What is the first action the nurse should take?

• A. Stop the infusion
• B. Slow the rate of infusion
• C. Take vital signs and observe for further deterioration
• D. Administer Benadryl and continue the infusion

Correct answer: A

Rationale: The correct action for the nurse to take when a client develops urticaria during a blood transfusion is to immediately stop the infusion. Urticaria is a sign of a transfusion reaction, and stopping the infusion is crucial to prevent the reaction from worsening. Slowing the rate of infusion (Choice B) is not appropriate in this situation as the reaction has already started. While taking vital signs and observing for further deterioration (Choice C) is important, the priority is to stop the transfusion. Administering Benadryl and continuing the infusion (Choice D) is not recommended until the client's condition has stabilized and healthcare provider orders have been obtained.
