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 a history of gout is experiencing an acute attack. Which medication should the nurse expect the healthcare provider to prescribe?
- A. Aspirin.
- B. Allopurinol (Zyloprim).
- C. Colchicine.
- D. Probenecid (Benemid).
Correct answer: C
Rationale: During an acute gout attack, the healthcare provider is likely to prescribe colchicine. Colchicine is commonly used to treat acute gout attacks because it works by reducing inflammation and alleviating pain associated with the condition. It is important to note that aspirin is not recommended for gout treatment and may even exacerbate the symptoms. Allopurinol and probenecid are medications used for long-term management of gout by reducing uric acid levels in the blood, but they are not typically prescribed during an acute attack. Therefore, colchicine is the most appropriate medication for managing an acute gout attack.
3. A patient with chronic heart failure is prescribed furosemide. What is the primary action of this medication?
- A. Increase cardiac output
- B. Reduce fluid retention
- C. Decrease heart rate
- D. Lower blood pressure
Correct answer: B
Rationale: Furosemide is a loop diuretic that acts by inhibiting sodium and chloride reabsorption in the loop of Henle, leading to increased diuresis. By reducing fluid retention, furosemide helps decrease the workload on the heart in patients with chronic heart failure. This medication does not directly increase cardiac output, decrease heart rate, or lower blood pressure as its primary action.
4. The healthcare provider formulates a nursing diagnosis of 'High risk for ineffective airway clearance' for a client with myasthenia gravis. What is the most likely cause for this nursing diagnosis?
- A. Pain during coughing.
- B. Diminished cough effort.
- C. Thick, dry secretions.
- D. Excessive inflammation.
Correct answer: B
Rationale: Clients with myasthenia gravis commonly experience muscle weakness, including in the muscles used for coughing. This diminished cough effort can lead to ineffective airway clearance, increasing the risk of respiratory complications. Therefore, the most likely cause for the nursing diagnosis 'High risk for ineffective airway clearance' in a client with myasthenia gravis is the diminished cough effort due to muscle weakness.
5. The healthcare provider is assessing a client with chronic obstructive pulmonary disease (COPD). Which finding should the provider expect?
- A. Increased anteroposterior chest diameter.
- B. Decreased respiratory rate.
- C. Dull percussion sounds over the lungs.
- D. Hyperresonance on chest percussion.
Correct answer: A
Rationale: The correct answer is A: Increased anteroposterior chest diameter. The increased anteroposterior chest diameter, often referred to as a barrel chest, is a common finding in clients with COPD due to hyperinflation of the lungs. This occurs because of the loss of lung elasticity and air trapping, leading to a more rounded chest shape. Choices B, C, and D are incorrect. Decreased respiratory rate is not typically associated with COPD; instead, an increased respiratory rate may be seen due to the body's compensatory mechanisms. Dull percussion sounds and hyperresonance on chest percussion are not characteristic findings in COPD. Dull percussion sounds may be indicative of consolidation or pleural effusion, while hyperresonance is more commonly associated with conditions like emphysema.
