Nursing Elites

1. A client is receiving warfarin for atrial fibrillation. Which of the following laboratory tests should the nurse expect to be ordered to monitor the effect of warfarin?

• A. Platelet count
• B. International normalized ratio (INR)
• C. Prothrombin time (PT)
• D. Partial thromboplastin time (PTT)

Correct answer: B

Rationale: The correct answer is B: International normalized ratio (INR). When a client is on warfarin therapy, the INR is monitored regularly to assess the anticoagulant effects of the medication. A therapeutic INR range for most indications is between 2.0 to 3.0. Choices A, C, and D are not typically used to monitor the effect of warfarin. Platelet count assesses the number of platelets in the blood, PT measures the clotting time of plasma, and PTT evaluates the intrinsic pathway of coagulation.

2. A nurse is administering medications to a group of clients. Which of the following occurrences requires the completion of an incident report?

• A. A client receives antibiotics 2 hours late.
• B. A client vomits within 20 minutes of taking morning medications.
• C. A client requests a statin to be administered at 2100.
• D. A client asks for pain medication 1 hour early.

Correct answer: A

Rationale: The correct answer is A. Administering antibiotics late must be reported as it can compromise the effectiveness of the treatment. This delay can lead to subtherapeutic levels of the antibiotic in the client's system, potentially reducing its efficacy in combating the infection. Choice B, a client vomiting shortly after taking medication, should be noted but does not necessarily require an incident report unless it is a frequent occurrence. It could indicate a possible adverse reaction or intolerance to the medication. Choice C, a client requesting a statin at a specific time, and choice D, a client asking for pain medication slightly earlier, do not involve medication errors or deviations that pose immediate risks to the client's health, so they do not require incident reports.

3. A healthcare provider is reviewing laboratory results for a client who is receiving heparin therapy. Which of the following results indicates that the medication is effective?

• A. Platelets 250,000/mm³
• B. aPTT 60 seconds
• C. Hemoglobin 15 g/dL
• D. INR 1.5

Correct answer: B

Rationale: An aPTT of 60 seconds indicates that the client is receiving an effective dose of heparin. The activated partial thromboplastin time (aPTT) measures the time it takes for blood to clot and is used to monitor heparin therapy. A therapeutic range for aPTT during heparin therapy is usually 1.5 to 2 times the control value, which is around 25-35 seconds. Platelets, hemoglobin, and INR values are not direct indicators of the effectiveness of heparin therapy.

4. A client receiving chemotherapy is being taught about infection prevention by a nurse. Which of the following instructions should the nurse include?

• A. Wear a mask when gardening.
• B. Avoid crowds to reduce the risk of infection.
• C. You should take a daily vitamin to prevent infection.
• D. Increase your intake of high-protein foods.

Correct answer: B

Rationale: The correct answer is B: 'Avoid crowds to reduce the risk of infection.' Clients receiving chemotherapy are immunocompromised, so avoiding crowds can help decrease the likelihood of exposure to infections. Wearing a mask when gardening (choice A) is important but not directly related to infection prevention in the context of chemotherapy. Taking a daily vitamin (choice C) may be beneficial for overall health but is not specifically focused on infection prevention. Increasing intake of high-protein foods (choice D) is essential for nutrition but does not directly address infection prevention.

5. A nurse is providing teaching to a client who is at 28 weeks of gestation and is scheduled for a glucose tolerance test. Which of the following instructions should the nurse include?

• A. You should avoid consuming any food or drink for 8 hours before the test.
• B. You should drink 8 oz of water 1 hour before the test.
• C. You should take an antacid before the test.
• D. You should drink a glass of milk 1 hour before the test.

Correct answer: A

Rationale: Clients should avoid consuming any food or drink for 8 hours before the glucose tolerance test to ensure accurate results. Choice A is the correct instruction for the client preparing for a glucose tolerance test. Drinking water, taking an antacid, or consuming milk before the test can interfere with the accuracy of the results. Water or any other substance might affect the concentration of glucose in the blood, leading to inaccurate test results. Antacids and milk can also interfere with the test outcome. Therefore, the client should follow the instruction to fast for 8 hours before the test.
