Nursing Elites

1. A client has a new prescription for Warfarin. Which of the following instructions should the nurse include?

• A. Avoid consuming foods high in vitamin K.
• B. Monitor your blood pressure regularly.
• C. Increase your intake of green, leafy vegetables.
• D. Take the medication with a high-fat meal.

Correct answer: A

Rationale: The correct answer is to advise the client to avoid consuming foods high in vitamin K. Warfarin's effectiveness can be affected by vitamin K intake. Clients should maintain a consistent intake of vitamin K and avoid sudden increases in foods high in vitamin K to ensure the medication works properly and consistently. Choices B, C, and D are incorrect. Monitoring blood pressure, increasing intake of green, leafy vegetables, or taking the medication with a high-fat meal are not specific instructions related to Warfarin therapy.

2. While caring for a client receiving Heparin therapy, which of the following laboratory tests should the nurse monitor to evaluate the effectiveness of the therapy?

• A. PT
• B. INR
• C. aPTT
• D. Platelet count

Correct answer: C

Rationale: The nurse should monitor the aPTT (activated partial thromboplastin time) when caring for a client receiving Heparin therapy. The aPTT reflects the intrinsic pathway of the clotting cascade and is used to monitor the effectiveness of heparin, which primarily affects this pathway by potentiating antithrombin III. Monitoring the aPTT helps ensure that the client's blood is within the therapeutic range to prevent thrombus formation. Choices A, B, and D are incorrect. PT (Prothrombin Time) and INR (International Normalized Ratio) are used to monitor Warfarin therapy, not Heparin. Platelet count is important in assessing for thrombocytopenia but is not a specific indicator of Heparin therapy effectiveness.

3. The healthcare professional is preparing to administer atenolol (Tenormin) to a client with angina. Which vital sign would cause the healthcare professional to question administering this drug?

• A. Respirations 12 breaths per minute
• B. Pulse 52 beats per minute
• C. Blood pressure 134/72
• D. Oxygen saturation 95%

Correct answer: B

Rationale: Atenolol is a beta-blocker medication that can lower heart rate. A pulse of 52 beats per minute is relatively low and administering atenolol could further decrease the heart rate, potentially leading to bradycardia. Monitoring the pulse rate and holding the medication if the pulse is below the prescribed parameters is crucial to prevent adverse effects such as bradycardia and hypotension.

4. A healthcare professional is administering a Dopamine infusion at a low dose to a client with severe heart failure. Which of the following findings is an expected effect of this medication?

• A. Lowered heart rate
• B. Increased myocardial contractility
• C. Decreased conduction through the AV node
• D. Vasoconstriction of renal blood vessels

Correct answer: B

Rationale: Dopamine, when administered at a low dose, is expected to increase myocardial contractility by stimulating beta1 receptors. This positive inotropic effect leads to an increase in cardiac output. Therefore, the correct answer is increased myocardial contractility, as it is a desired effect of administering dopamine to a client with severe heart failure.

5. A healthcare professional is educating a client who has a new prescription for warfarin. Which of the following statements should the healthcare professional include?

• A. Avoid foods high in vitamin K.
• B. Report any signs of bleeding to your healthcare provider.
• C. Use a soft toothbrush to prevent gum bleeding.
• D. Use an electric razor to prevent cuts.

Correct answer: B

Rationale: The correct statement that the healthcare professional should include when educating a client prescribed warfarin is to report any signs of bleeding to their healthcare provider. Bleeding can indicate excessive anticoagulation, which is a serious side effect of warfarin. Prompt reporting of bleeding symptoms is crucial to prevent complications. Choices A, C, and D are incorrect. While avoiding foods high in vitamin K may be important when taking warfarin due to its interaction with the medication, it is not the priority over reporting signs of bleeding. Using a soft toothbrush and electric razor are general precautions for individuals on anticoagulants but are not as critical as reporting bleeding symptoms.
