Nursing Elites

1. A nurse is caring 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 medication?

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

Correct answer: D

Rationale: The correct answer is D, International normalized ratio (INR). INR is used to monitor the therapeutic effect of warfarin, an anticoagulant medication. Warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors. Monitoring the INR helps assess how well the medication is working to prevent blood clots. Choices A, B, and C are not specific indicators for monitoring the effectiveness of warfarin. Hemoglobin levels primarily assess the oxygen-carrying capacity of red blood cells, platelet count evaluates the clotting ability of blood, and PT measures the time it takes for blood to clot. While these values are important for overall health assessment, they do not directly reflect the anticoagulant effects of warfarin.

2. A healthcare provider is preparing to administer an intramuscular injection to a client. Which of the following sites should the healthcare provider select?

• A. Deltoid
• B. Vastus lateralis
• C. Rectus femoris
• D. Dorsogluteal

Correct answer: B

Rationale: The vastus lateralis is the preferred site for intramuscular injections in adults due to its large muscle mass and low risk of complications. The deltoid, although a common site for vaccines, has a smaller muscle mass and may not be suitable for all types of medications. The rectus femoris is a muscle in the thigh that is more commonly used for intramuscular injections in infants. The dorsogluteal site is no longer recommended due to its proximity to major nerves and blood vessels.

3. A nurse is reviewing the laboratory report of a client who has been receiving lithium carbonate for the past 12 months. The nurse notes a lithium level of 0.8 mEq/L. Which of the following orders from the provider should the nurse expect?

• A. Withhold the next dose.
• B. Increase the dosage.
• C. Discontinue the medication.
• D. Administer the medication.

Correct answer: D

Rationale: Administering the medication is appropriate for a stable lithium level of 0.8 mEq/L. A level of 0.8 mEq/L falls within the therapeutic range for lithium, indicating that the client is receiving an adequate dose to maintain therapeutic effects. Withholding the next dose, increasing the dosage, or discontinuing the medication would not be indicated at this lithium level as it is within the desired range for therapeutic benefit. Therefore, the correct action would be to continue administering the medication to ensure the client maintains the therapeutic level of lithium.

4. A nurse is assessing a client who is 2 hours postoperative following a gastrectomy. Which of the following findings should the nurse report to the provider?

• A. Heart rate of 94/min
• B. Oxygen saturation of 88%
• C. Respiratory rate of 18/min
• D. Temperature of 37.6°C (99.7°F)

Correct answer: B

Rationale: An oxygen saturation of 88% indicates hypoxemia, which is a serious condition post-gastrectomy. Hypoxemia can lead to inadequate oxygen delivery to tissues, potentially causing complications like organ dysfunction or failure. This finding requires immediate attention to prevent further deterioration. The heart rate, respiratory rate, and temperature are within normal ranges for a client post-gastrectomy, so they do not require immediate reporting to the provider.

5. A nurse is providing discharge teaching to a client who is postoperative following a mastectomy. Which of the following instructions should the nurse include?

• A. Avoid using deodorant until the incision heals.
• B. Perform arm exercises 24 hours after surgery.
• C. Wear tight-fitting clothing to support the incision.
• D. Perform arm exercises 2 days after surgery.

Correct answer: A

Rationale: The correct instruction for the nurse to include is to advise the client to avoid using deodorant until the incision heals. Using deodorant can lead to skin irritation, which should be prevented following a mastectomy. Choice B is incorrect because performing arm exercises should typically be delayed until recommended by the healthcare provider to prevent strain on the surgical site. Choice C is incorrect as tight-fitting clothing can increase discomfort and hinder proper healing. Choice D is also incorrect because initiating arm exercises should be based on the healthcare provider's guidance and not a specific timeframe.
