Nursing Elites

1. A client with deep vein thrombosis (DVT) is receiving heparin therapy. Which laboratory test should the nurse monitor to assess the effectiveness of the therapy?

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

Correct answer: C

Rationale: Activated partial thromboplastin time (aPTT) is the appropriate laboratory test to monitor the effectiveness of heparin therapy. Heparin works by prolonging the clotting time, which is reflected in the aPTT results. Monitoring aPTT helps ensure the patient is within the therapeutic range and not at risk of bleeding or clotting complications. Prothrombin time (PT) (Choice A) primarily measures the extrinsic pathway of coagulation and is used to monitor warfarin therapy, not heparin. Platelet count (Choice B) assesses the number of platelets present in the blood and is not specific to monitoring heparin therapy. International normalized ratio (INR) (Choice D) is used to monitor warfarin therapy, not heparin.

2. A client with osteoporosis is being discharged home. Which instruction should the nurse include in the discharge teaching?

• A. Avoid weight-bearing exercises.
• B. Take calcium supplements with meals.
• C. Limit vitamin D intake.
• D. Increase intake of caffeine-containing beverages.

Correct answer: B

Rationale: Taking calcium supplements with meals is a crucial instruction for a client with osteoporosis. Calcium absorption is enhanced when taken with food, and proper calcium intake is essential for managing osteoporosis effectively by promoting bone health and density. Avoiding weight-bearing exercises (Choice A) is incorrect because these exercises help improve bone strength. Limiting vitamin D intake (Choice C) is also incorrect as vitamin D is necessary for calcium absorption. Increasing caffeine intake (Choice D) is not recommended as caffeine can interfere with calcium absorption.

3. When covering another nurse's assignment during a lunch break, based on the status report provided, which client should the charge nurse check first?

• A. The client admitted yesterday with diabetic ketoacidosis whose blood glucose level is now 195 mg/dl.
• B. The client with an ileal conduit created two days ago with a scant amount of blood in the drainage pouch.
• C. The client post-triple coronary bypass four days ago who has serosanguinous drainage in the chest tube.
• D. The client with a pneumothorax secondary to a gunshot wound with a current pulse oximeter reading of 90%.

Correct answer: D

Rationale: The client with a pneumothorax and a pulse oximeter reading of 90% indicates potential respiratory compromise, requiring immediate attention to prevent further deterioration.

4. A client with a history of deep vein thrombosis (DVT) is receiving warfarin (Coumadin). Which laboratory value indicates a therapeutic effect of the medication?

• A. INR of 2.5.
• B. PTT of 45 seconds.
• C. Hemoglobin of 12 g/dL.
• D. Platelet count of 150,000/mm³.

Correct answer: A

Rationale: An INR (International Normalized Ratio) of 2.5 indicates a therapeutic level for clients receiving warfarin (Coumadin) to prevent thromboembolism. It is essential to monitor INR levels regularly when on warfarin therapy to ensure that the blood's ability to clot is within the desired range to prevent both clotting and excessive bleeding.

5. A client with chronic kidney disease (CKD) is scheduled for a renal biopsy. Which pre-procedure instruction should the nurse provide?

• A. Maintain a low-protein diet for 24 hours before the biopsy.
• B. Avoid taking anticoagulant medications for one week before the biopsy.
• C. Drink plenty of fluids before the procedure.
• D. Take your routine medications with a full glass of water before the biopsy.

Correct answer: B

Rationale: The correct pre-procedure instruction the nurse should provide to a client with chronic kidney disease (CKD) scheduled for a renal biopsy is to avoid taking anticoagulant medications for one week before the biopsy. This instruction is crucial to reduce the risk of bleeding during the procedure, as anticoagulants can increase the chance of bleeding complications. Choices A, C, and D are incorrect because maintaining a low-protein diet, drinking plenty of fluids, or taking routine medications with water are not specifically related to reducing the risk of bleeding associated with a renal biopsy in a client with CKD.
