Nursing Elites

1. A client is receiving heparin therapy. Which laboratory value should be monitored by the nurse to evaluate the effectiveness of the therapy?

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

Correct answer: B

Rationale: The activated partial thromboplastin time (aPTT) is specifically used to monitor the effectiveness of heparin therapy. It should be maintained at 1.5 to 2 times the normal level. Monitoring aPTT helps ensure that the therapeutic range of heparin is achieved to prevent clot formation while minimizing the risk of bleeding complications. Choice A (PT) is incorrect as it is used to monitor warfarin therapy, not heparin. Choice C (INR) is also incorrect as it is primarily used to monitor warfarin therapy. Choice D (Platelet count) is not directly related to monitoring the effectiveness of heparin therapy.

2. A client is receiving IV Dopamine for the treatment of shock. Which of the following findings indicates that the medication is effective?

• A. Increased heart rate
• B. Decreased blood pressure
• C. Increased urine output
• D. Decreased respiratory rate

Correct answer: C

Rationale: Dopamine is a medication used in shock to increase cardiac output and improve renal perfusion. An increase in urine output indicates that the medication is effective as it shows improved renal perfusion and kidney function, which are essential for managing shock effectively. Choices A, B, and D are incorrect as an increased heart rate, decreased blood pressure, and decreased respiratory rate are not direct indicators of the effectiveness of IV Dopamine in treating shock.

3. A client has a prescription for Levothyroxine. Which of the following instructions should the nurse include?

• A. Take this medication on an empty stomach.
• B. Take this medication with food.
• C. Take this medication at bedtime.
• D. Take this medication with antacids.

Correct answer: A

Rationale: Levothyroxine should be taken on an empty stomach to increase absorption and efficacy. Taking it with food or antacids can interfere with its absorption, leading to reduced effectiveness of the medication.

4. A healthcare professional is preparing to administer heparin 15,000 units subcutaneously every 12 hr. The amount available is heparin injection 20,000 units/mL. How many mL should the healthcare professional administer per dose?

• A. 0.8 mL
• B. 0.75 mL
• C. 0.5 mL
• D. 1 mL

Correct answer: A

Rationale: To calculate the volume to administer, use the formula: (Desired dose / Concentration) = Volume to administer. In this case, (15,000 units / 20,000 units/mL) = 0.75 mL, which is rounded up to 0.8 mL. Therefore, the healthcare professional should administer 0.8 mL per dose of heparin. Choice B (0.75 mL) is incorrect as it is the exact calculated volume but needs to be rounded up. Choices C (0.5 mL) and D (1 mL) are incorrect as they do not reflect the correct calculated volume for the desired dose of heparin.

5. When teaching a client with a prescription for Cephalexin, which of the following instructions should the nurse include?

• A. Take the medication with an antacid.
• B. Avoid dairy products while taking this medication.
• C. Expect your stools to turn black.
• D. Complete the full course of medication.

Correct answer: D

Rationale: The correct instruction for a client prescribed with Cephalexin is to complete the full course of medication. This is crucial to ensure the infection is completely treated and to reduce the risk of antibiotic resistance. Choices A, B, and C are incorrect. Taking Cephalexin with an antacid is generally not recommended as it may reduce its effectiveness. While dairy products can interfere with certain antibiotics, they do not have a direct interaction with Cephalexin. Stools turning black is not an expected side effect of Cephalexin.
