1. A patient with a diagnosis of deep vein thrombosis (DVT) is receiving heparin therapy. Which laboratory test should the nurse monitor to evaluate the effectiveness of the heparin therapy?
- A. Prothrombin time (PT)
- B. Partial thromboplastin time (PTT)
- C. Bleeding time
- D. Platelet count
Correct answer: B
Rationale: The correct answer is B: Partial thromboplastin time (PTT). Heparin affects the intrinsic pathway of the coagulation cascade, which is reflected by changes in the PTT. Monitoring the PTT helps ensure that the patient's blood is within the desired therapeutic range and prevents complications related to clotting or bleeding. Prothrombin time (PT) primarily assesses the extrinsic pathway and is not as sensitive to heparin therapy. Bleeding time and platelet count are not specific tests for monitoring the effectiveness of heparin therapy in DVT.
2. A client's healthcare provider has ordered a 'liver panel' in response to the client's development of jaundice. When reviewing the results of this laboratory testing, the nurse should expect to review what blood tests? Select one that doesn't apply.
- A. Alanine aminotransferase (ALT)
- B. C-reactive protein (CRP)
- C. Gamma-glutamyl transferase (GGT)
- D. Aspartate aminotransferase (AST)
Correct answer: B
Rationale: A 'liver panel' is a group of blood tests used to evaluate liver function. The components typically include ALT, GGT, and AST. While C-reactive protein (CRP) is a marker of inflammation and not part of a standard liver panel, it may be ordered for other diagnostic purposes.
3. A patient with hyperthyroidism is to receive radioactive iodine therapy. What information should the nurse include in the patient teaching plan?
- A. Avoid close contact with pregnant women for one week.
- B. Take iodine supplement daily.
- C. Restrict fluid intake to 1 liter per day.
- D. Use disposable utensils for all meals.
Correct answer: A
Rationale: The correct answer is to avoid close contact with pregnant women for one week. This precaution is essential to prevent radiation exposure to vulnerable populations. Pregnant women and small children are more sensitive to radiation, making it crucial for patients undergoing radioactive iodine therapy to avoid close contact with them for a specified period. Choices B, C, and D are incorrect because taking iodine supplements daily is not necessary for patients receiving radioactive iodine therapy. Restricting fluid intake to 1 liter per day is not a standard recommendation for radioactive iodine therapy. Using disposable utensils for all meals is not a specific precaution related to radioactive iodine therapy.
4. The healthcare provider is assessing a client with Raynaud's phenomenon. Which finding should the healthcare provider expect?
- A. Thickened and hardened skin.
- B. Painless ulcers on the fingertips.
- C. Episodes of cyanosis and pallor in the fingers.
- D. Red, scaly patches on the hands.
Correct answer: C
Rationale: Raynaud's phenomenon is characterized by vasospasm, leading to episodes of cyanosis (bluish discoloration) and pallor (pale color) in the fingers or toes, often triggered by cold temperatures or stress. This occurs due to the reduced blood flow during vasospastic episodes, causing the discoloration. Choices A, B, and D are incorrect findings associated with other conditions and are not typical of Raynaud's phenomenon.
5. A patient with anemia is prescribed ferrous sulfate. What advice should the nurse give regarding the administration of this medication?
- A. Take with dairy products to increase absorption.
- B. Take on an empty stomach for best absorption.
- C. Avoid vitamin C while taking this medication.
- D. Take before bedtime.
Correct answer: B
Rationale: The correct advice for the administration of ferrous sulfate is to take it on an empty stomach for best absorption. This enhances the absorption of iron. If gastrointestinal upset occurs, the medication can be taken with food. Taking ferrous sulfate with dairy products is not recommended as calcium can inhibit iron absorption. Taking it before bedtime is also not recommended. Vitamin C can actually help with the absorption of iron and is often recommended to be taken alongside iron supplements to enhance absorption. Therefore, avoiding vitamin C while taking ferrous sulfate is not correct.
