Nursing Elites

1. A client is prescribed warfarin for anticoagulation. Which of the following laboratory values should the nurse monitor?

• A. PT and INR
• B. Blood glucose levels
• C. Complete blood count (CBC)
• D. Platelet count

Correct answer: A

Rationale: The correct answer is A: PT and INR. Warfarin is an anticoagulant that affects the clotting mechanism by inhibiting vitamin K-dependent clotting factors. The PT (Prothrombin Time) and INR (International Normalized Ratio) are specific laboratory values used to monitor the effectiveness and safety of warfarin therapy. These values help healthcare providers adjust the warfarin dosage to maintain the desired level of anticoagulation. Choices B, C, and D are incorrect because blood glucose levels, complete blood count (CBC), and platelet count are not directly monitored to assess the effects of warfarin therapy.

2. A client has been prescribed raloxiphene. As the nurse, you know that raloxiphene is used to treat:

• A. Migraines
• B. Hypertension
• C. Osteoporosis
• D. Heart disease

Correct answer: C

Rationale: Raloxiphene (Evista) is a selective estrogen receptor modulator (SERM) used primarily to prevent and treat osteoporosis in postmenopausal women. It helps to maintain bone density and reduce the risk of fractures by mimicking the effects of estrogen on bone tissue. It is not indicated for the treatment of migraines, hypertension, or heart disease. Therefore, the correct answer is osteoporosis (Choice C). Choices A, B, and D are incorrect as raloxiphene is not used to treat migraines, hypertension, or heart disease.

3. A healthcare provider is caring for a patient and realizes they administered the wrong medication. What action should the healthcare provider take first?

• A. Notify the provider.
• B. Report the incident to the risk manager.
• C. Check the condition of the patient.
• D. Complete an incident report.

Correct answer: C

Rationale: The healthcare provider should first assess the patient to determine if any harm has occurred as a result of the medication error. Checking the patient's condition takes precedence as it allows for immediate intervention if necessary. Notifying the provider (choice A) can come later once the patient's condition is assessed. Reporting to the risk manager (choice B) and completing an incident report (choice D) are important steps but should follow the initial assessment of the patient to ensure timely and appropriate actions are taken.

4. A nurse is caring for a client with celiac disease. Which food should be removed from the meal tray?

• A. Cornbread
• B. Mashed potatoes
• C. Lentils
• D. Tortillas

Correct answer: D

Rationale: The correct answer is D, Tortillas. Clients with celiac disease should avoid gluten, which is often found in tortillas. Cornbread, mashed potatoes, and lentils are gluten-free options, making them safe for individuals with celiac disease. Therefore, the other choices (A, B, and C) do not need to be removed from the meal tray.

5. A nurse is preparing to administer lactated Ringer's (LR) 1,000 mL IV to infuse over 8 hr. The drop factor of the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min?

• A. 19 gtt/min
• B. 20 gtt/min
• C. 21 gtt/min
• D. 22 gtt/min

Correct answer: C

Rationale: Calculation: 1000 mL / 480 minutes × 10 gtt/mL = 20.83, rounded to 21 gtt/min. This ensures proper IV fluid administration over the prescribed time. Choice C is the correct answer as it reflects the accurate calculation based on the given parameters. Choice A is incorrect because it does not accurately calculate the infusion rate. Choice B is incorrect as it does not consider the precise calculation required. Choice D is incorrect as it deviates from the correct calculation.
