1. Which lab value is critical for a patient on heparin therapy?
- A. Monitor aPTT
- B. Monitor INR
- C. Monitor platelet count
- D. Monitor sodium levels
Correct answer: A
Rationale: The correct answer is to monitor aPTT. Activated Partial Thromboplastin Time (aPTT) is crucial for patients on heparin therapy as it helps determine the clotting ability of the blood. By monitoring aPTT, healthcare providers can adjust the dosage of heparin to maintain therapeutic levels and prevent bleeding complications. Monitoring INR is more commonly associated with warfarin therapy, not heparin. Monitoring platelet count is important for assessing the risk of bleeding or clotting disorders but is not specific to heparin therapy. Monitoring sodium levels is not directly related to assessing the effectiveness or safety of heparin therapy.
2. A nurse is reviewing the medical history of a client who has angina. Which of the following findings in the client's medical history should the nurse identify as a risk factor for angina?
- A. Hyperlipidemia.
- B. COPD.
- C. Seizure disorder.
- D. Hyponatremia.
Correct answer: A
Rationale: The correct answer is A: Hyperlipidemia. Hyperlipidemia, which is an elevated level of lipids (fats) in the blood, is a well-established risk factor for angina. High levels of lipids can lead to atherosclerosis, a condition where fatty deposits build up in the arteries, reducing blood flow to the heart muscle and increasing the risk of angina. Choice B, COPD (Chronic Obstructive Pulmonary Disease), is not directly linked to an increased risk of angina. COPD primarily affects the lungs and is not a known risk factor for angina. Choice C, Seizure disorder, and Choice D, Hyponatremia (low sodium levels), are also not typically associated with an increased risk of angina. While medical conditions like hypertension, diabetes, and smoking are other common risk factors for angina, hyperlipidemia is specifically known for its impact on blood vessels, making it a key risk factor to identify in a client's medical history.
3. A client has a nasogastric tube and is receiving intermittent enteral feedings. Which of the following actions should the nurse take to prevent aspiration?
- A. Administer a bolus feeding over 10 minutes.
- B. Elevate the head of the bed to 45 degrees during feedings.
- C. Flush the tube with 10 mL of sterile water before feedings.
- D. Position the client on the left side during feedings.
Correct answer: B
Rationale: To prevent aspiration in clients with a nasogastric tube receiving intermittent enteral feedings, the nurse should elevate the head of the bed to 45 degrees during feedings. This position helps reduce the risk of regurgitation and aspiration of the feeding contents. Administering a bolus feeding over 10 minutes (choice A) may not prevent aspiration as effectively as elevating the head of the bed. Flushing the tube with sterile water before feedings (choice C) is important for tube patency but does not directly prevent aspiration. Positioning the client on the left side during feedings (choice D) is not the recommended action to prevent aspiration; elevating the head of the bed is more effective.
4. A client with asthma is prescribed a corticosteroid inhaler. Which of the following instructions should the nurse include?
- A. Use the inhaler as needed for acute symptoms.
- B. Rinse the mouth after each use.
- C. Take the medication only during asthma attacks.
- D. Administer a bronchodilator after using the corticosteroid.
Correct answer: B
Rationale: The correct instruction is to rinse the mouth after each use of a corticosteroid inhaler to prevent oral candidiasis (thrush). Choice A is incorrect because corticosteroid inhalers are usually used on a regular schedule to control asthma symptoms, not just for acute symptoms. Choice C is incorrect as corticosteroid inhalers are typically used for long-term management, not just during asthma attacks. Choice D is incorrect as administering a bronchodilator after using a corticosteroid is not a standard practice and is not necessary for the effectiveness of the corticosteroid inhaler.
5. How should a healthcare provider monitor a patient with fluid overload?
- A. Monitor daily weight
- B. Check for edema
- C. Monitor input and output
- D. Monitor blood pressure
Correct answer: A
Rationale: Monitoring daily weight is crucial in assessing fluid retention accurately in a patient with fluid overload. Changes in weight can indicate fluid accumulation or loss, providing valuable information for healthcare providers. Checking for edema (choice B) is important but may not always accurately reflect total body fluid status. Monitoring input and output (choice C) and blood pressure (choice D) are also essential aspects of patient assessment, but they may not directly reflect the extent of fluid overload as effectively as monitoring daily weight.
