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 75-year-old patient is admitted for pancreatitis. Which tool would be the most appropriate for the nurse to use during the admission assessment?
- A. Drug Abuse Screening Test (DAST-10)
- B. Clinical Institute Withdrawal Assessment of Alcohol Scale, Revised (CIWA-Ar)
- C. Screening Test-Geriatric Version (SMAST-G)
- D. Mini-Mental State Examination
Correct answer: C
Rationale: The most appropriate tool for the nurse to use during the admission assessment of a 75-year-old patient admitted for pancreatitis is the Screening Test-Geriatric Version (SMAST-G). Since alcohol abuse is a common factor associated with pancreatitis, screening for alcohol use is crucial. The SMAST-G is a validated short-form alcoholism screening instrument tailored for older adults. If the patient screens positively on the SMAST-G, then the CIWA-Ar would be useful for further assessment. The Drug Abuse Screening Test (DAST-10) provides information on substance use in general, not specific to alcohol. The Mini-Mental State Examination is used to assess cognitive function, not alcohol abuse.
3. A client with a history of atrial fibrillation is prescribed dabigatran (Pradaxa). Which instruction should the nurse include in the client's teaching?
- A. Take the medication with food to improve absorption.
- B. Avoid foods high in vitamin K.
- C. Take the medication at the same time each day.
- D. Increase your intake of high-potassium foods.
Correct answer: C
Rationale: The correct instruction for the nurse to include in the client's teaching regarding dabigatran (Pradaxa) is to take the medication at the same time each day. This ensures a consistent blood level and effectiveness of the medication, which is crucial in managing atrial fibrillation and preventing complications. It helps maintain a steady therapeutic effect and reduces the risk of erratic drug levels in the body.
4. A client with chronic kidney disease is prescribed a low-protein diet. Which laboratory result should the nurse monitor to evaluate the effectiveness of the diet?
- A. Blood urea nitrogen (BUN)
- B. Serum potassium
- C. Serum calcium
- D. Creatinine clearance
Correct answer: A
Rationale: Blood urea nitrogen (BUN) levels should be monitored to assess the effectiveness of a low-protein diet in clients with chronic kidney disease. BUN levels reflect the breakdown of protein in the body, and a low-protein diet aims to reduce BUN levels to lessen the workload on the kidneys. Therefore, monitoring BUN levels is crucial in managing kidney function and evaluating the impact of dietary modifications. Serum potassium, serum calcium, and creatinine clearance are important parameters to monitor in clients with chronic kidney disease, but they are not specifically indicative of the effectiveness of a low-protein diet. Serum potassium levels are crucial in assessing electrolyte balance, serum calcium levels are important for bone health and nerve function, and creatinine clearance reflects kidney function overall, not just the impact of a low-protein diet.
5. A 65-year-old woman presents with difficulty swallowing, weight loss, and a history of long-standing heartburn. She has been on proton-pump inhibitors for years, but her symptoms have worsened. What is the most likely diagnosis?
- A. Peptic stricture
- B. Esophageal cancer
- C. Achalasia
- D. Esophageal spasm
Correct answer: B
Rationale: The presentation of difficulty swallowing, weight loss, and worsening symptoms despite long-term use of proton-pump inhibitors raises suspicion for esophageal cancer, especially in a patient with a history of chronic heartburn. Esophageal cancer should be considered in this scenario due to the concerning symptoms and lack of improvement despite appropriate medical management.
