1. Which laboratory test should the nurse monitor to determine the effectiveness of heparin therapy for a client with deep vein thrombosis?
- A. Platelet count
- B. Prothrombin time (PT)
- C. Activated partial thromboplastin time (aPTT)
- D. Hemoglobin and hematocrit
Correct answer: C
Rationale: The activated partial thromboplastin time (aPTT) is the specific laboratory test used to monitor the effectiveness of heparin therapy in patients with deep vein thrombosis. It measures the time it takes for blood to clot and is crucial in assessing the therapeutic range of heparin. Platelet count, prothrombin time (PT), and hemoglobin and hematocrit levels are important parameters in assessing coagulation and blood status but do not directly indicate the effectiveness of heparin therapy.
2. A client has begun therapy with theophylline (Theo-24). The nurse tells the client to limit the intake of which of the following while taking this medication?
- A. Oranges and pineapple
- B. Coffee, cola, and chocolate
- C. Oysters, lobster, and shrimp
- D. Cottage cheese, cream cheese, and dairy creamers
Correct answer: B
Rationale: Theophylline is a xanthine bronchodilator. Xanthines are found in coffee, cola, and chocolate. These foods should be limited while taking theophylline to prevent potential drug interactions or adverse effects.
3. A client is taking levothyroxine (Synthroid). The nurse instructs the client to notify the health care provider (HCP) if which of the following occurs?
- A. Fatigue
- B. Tremors
- C. Cold intolerance
- D. Excessively dry skin
Correct answer: B
Rationale: Tremors are a sign of excessive doses of levothyroxine, indicating hyperthyroidism. It is important for the client to report tremors to the healthcare provider to prevent complications associated with overdosing on levothyroxine.
4. The client has reinforced instructions for taking cholestyramine (Questran). Which statement indicates a need for further instructions?
- A. I will continue taking vitamin supplements.
- B. This medication will help lower my cholesterol.
- C. This medication should only be taken with water.
- D. A high-fiber diet is important while taking this medication.
Correct answer: C
Rationale: The correct answer is C because cholestyramine should not only be taken with water. Flavored products or fruit juices can improve the taste. Choices A, B, and D are all correct statements. It is important for the client to continue taking vitamin supplements, understand that cholestyramine helps lower cholesterol, and maintain a high-fiber diet while taking this medication to enhance its effectiveness.
5. A client with chronic pain is prescribed transdermal fentanyl (Duragesic) patches. Which instruction should the nurse include in the teaching plan?
- A. Apply the patch to a different site each time.
- B. Avoid using heating pads over the patch.
- C. Change the patch every 72 hours.
- D. Remove the old patch before applying the new one.
Correct answer: B
Rationale: Clients using transdermal fentanyl (Duragesic) patches should avoid using heating pads over the patch as heat can increase the release of the medication, potentially leading to overdose. The patch should be applied to a different site each time, changed every 72 hours, and the old patch should be removed before applying a new one to prevent accidental overdose or excessive drug absorption.
