Nursing Elites

1. The nurse is caring for a client who is receiving heparin therapy. Which laboratory value should the nurse monitor to determine the effectiveness of the therapy?

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

Correct answer: C

Rationale: The correct answer is C, International Normalized Ratio (INR). While INR is commonly used to monitor the effectiveness of warfarin therapy, in the case of heparin therapy, the Partial Thromboplastin Time (PTT) is the preferred test. Choice A, Prothrombin Time (PT), measures the activity of the extrinsic pathway of coagulation and is not the best choice for monitoring heparin therapy. Choice D, Activated Partial Thromboplastin Time (aPTT), is similar to PTT and is used to monitor heparin therapy, but PTT is the more specific test. Therefore, monitoring PTT is crucial in determining the effectiveness and safety of heparin therapy.

2. A client with diabetes mellitus reports feeling shaky and has a blood glucose level of 60 mg/dl. What action should the nurse take?

• A. Administer 15 grams of carbohydrate
• B. Administer a glucagon injection
• C. Provide a snack with protein
• D. Encourage the client to rest

Correct answer: A

Rationale: In the scenario described, the client is experiencing hypoglycemia with a blood glucose level of 60 mg/dl. The appropriate action for the nurse to take is to administer 15 grams of carbohydrate. Carbohydrate intake helps to rapidly raise blood sugar levels in cases of hypoglycemia. Administering a glucagon injection (Choice B) is not the initial treatment for mild hypoglycemia; it is typically used for severe hypoglycemia when the client is unable to consume oral carbohydrates. Providing a snack with protein (Choice C) is not the first-line intervention for hypoglycemia; immediate carbohydrate intake is necessary to raise blood sugar levels quickly. Encouraging the client to rest (Choice D) may be appropriate after administering the carbohydrate, but the priority is to address the low blood glucose levels by administering carbohydrates first.

3. Which assessment finding is most indicative of deep vein thrombosis (DVT) in a client's right leg?

• A. Dorsiflexes the right foot and left on command
• B. A 3 by 5 cm ecchymosis area covering the right calf
• C. Right calf is 3 cm larger in circumference than the left
• D. Bilateral lower extremity has 3+ pitting edema

Correct answer: C

Rationale: The correct answer is C because a significant increase in the circumference of the right calf compared to the left calf is a classic sign of deep vein thrombosis (DVT). Option A is incorrect as dorsiflexing the right foot and left on command does not specifically indicate DVT. Option B describes an ecchymosis area which is more indicative of a bruise rather than DVT. Option D suggests bilateral lower extremity edema, which is not specific to DVT and can be seen in various conditions such as heart failure or renal issues.

4. The nurse is preparing to administer a unit of packed red blood cells (PRBCs) to a client. Which action is most important for the nurse to take?

• A. Verify the client's blood type
• B. Ensure the PRBCs are warm
• C. Check the client's vital signs
• D. Obtain the client's consent

Correct answer: A

Rationale: Verifying the client's blood type is crucial before administering PRBCs to ensure compatibility and prevent transfusion reactions. Checking the client's blood type is essential in blood transfusions. Ensuring the PRBCs are warm is not a priority as the temperature should be within a specific range regardless of the client's preference. Checking the client's vital signs is important but not as crucial as verifying the blood type before a blood transfusion. Obtaining the client's consent is important for any procedure but does not directly impact the safety and success of administering PRBCs.

5. A client who is bleeding after a vaginal delivery receives a prescription for methylergonovine (Methergine) 0.4 mg IM every 2 hours, not to exceed 5 doses. The medication is available in ampules containing 0.2 mg/ml. What is the maximum dosage in mg that the nurse should administer to this client?

• A. Encourage oral fluids as tolerated
• B. Decrease oral intake to 200 ml
• C. Allow the client to have exactly 400 ml oral intake
• D. Limit oral intake to 900 to 1,000 ml

Correct answer: D

Rationale: The maximum dosage the nurse should administer is 2 mg. This is calculated based on the prescription of 0.4 mg IM every 2 hours, not to exceed 5 doses. Since the medication is available in ampules containing 0.2 mg/ml, the nurse should administer 2 ml (0.2 mg/ml x 10 ml) for each dose, not exceeding 5 doses. Therefore, the nurse should limit the client's oral intake to 900 to 1,000 ml, to avoid exceeding the maximum dosage of 2 mg.
