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 patient with a diagnosis of peptic ulcer disease is prescribed omeprazole. When should the patient take this medication for optimal effectiveness?
- A. With meals
- B. At bedtime
- C. Before meals
- D. After meals
Correct answer: C
Rationale: Omeprazole is best taken before meals for optimal effectiveness in reducing stomach acid production and promoting ulcer healing. Taking it before meals allows the medication to act on the proton pumps before food intake triggers acid production, thereby maximizing its therapeutic benefits. Choices A, B, and D are incorrect because taking omeprazole with meals, at bedtime, or after meals may not align with its mechanism of action, potentially reducing its effectiveness in managing peptic ulcer disease.
3. The sister of a patient diagnosed with BRCA gene-related breast cancer asks the nurse, 'Do you think I should be tested for the gene?' Which response by the nurse is most appropriate?
- A. In most cases, breast cancer is not caused by the BRCA gene.
- B. It depends on how you will feel if the test is positive for the BRCA gene.
- C. There are many things to consider before deciding to have genetic testing.
- D. You should decide first whether you are willing to have a bilateral mastectomy.
Correct answer: C
Rationale: The most appropriate response by the nurse is C: 'There are many things to consider before deciding to have genetic testing.' Genetic testing for BRCA gene mutations is a complex decision that involves various factors such as emotional readiness, potential impact on insurance and employability, and the implications of test results. Option A is incorrect because although most breast cancers are not related to BRCA gene mutations, individuals with these mutations have a significantly higher risk. Option B is not ideal as it oversimplifies the decision-making process by focusing solely on emotional aspects. Option D is incorrect as it implies a predetermined course of action (mastectomy) before even undergoing genetic testing, which is not appropriate.
4. A patient with chronic pain is prescribed a fentanyl patch. What is the most important instruction for the nurse to provide?
- A. Apply the patch to a different site each time.
- B. Change the patch every 72 hours.
- C. Avoid using additional heating pads over the patch.
- D. Remove the patch before showering.
Correct answer: B
Rationale: The most important instruction for the nurse to provide to a patient prescribed a fentanyl patch is to change the patch every 72 hours. This ensures consistent pain control and prevents complications. It is crucial to rotate the application sites to prevent skin irritation or reactions. Using additional heating pads over the patch should be avoided as it can increase the absorption of the medication, leading to overdose or adverse effects. Removing the patch before showering is not necessary as long as the patch is securely in place.
5. A client with chronic kidney disease (CKD) has an arteriovenous (AV) fistula for hemodialysis. Which finding should the nurse report to the healthcare provider immediately?
- A. No bruit or thrill over the AV fistula.
- B. Redness at the site of the AV fistula.
- C. Client's complaint of pain at the AV fistula site.
- D. Swelling of the hand on the side of the AV fistula.
Correct answer: A
Rationale: In a client with a chronic kidney disease who has an arteriovenous (AV) fistula for hemodialysis, the absence of a bruit (a humming sound) or thrill (vibratory sensation) over the AV fistula indicates a potential occlusion. This finding suggests inadequate blood flow through the AV fistula, which is a critical issue requiring immediate intervention to prevent complications such as thrombosis or clot formation. Reporting this absence of bruit or thrill promptly to the healthcare provider is essential to ensure timely assessment and management to maintain vascular access for hemodialysis.
