1. A healthcare provider is reviewing laboratory results for a client who is receiving heparin therapy. Which of the following results indicates that the medication is effective?
- A. Platelets 250,000/mm³
- B. aPTT 60 seconds
- C. Hemoglobin 15 g/dL
- D. INR 1.5
Correct answer: B
Rationale: An aPTT of 60 seconds indicates that the client is receiving an effective dose of heparin. The activated partial thromboplastin time (aPTT) measures the time it takes for blood to clot and is used to monitor heparin therapy. A therapeutic range for aPTT during heparin therapy is usually 1.5 to 2 times the control value, which is around 25-35 seconds. Platelets, hemoglobin, and INR values are not direct indicators of the effectiveness of heparin therapy.
2. Which medication is used to manage hyperthyroidism?
- A. Levothyroxine
- B. Methimazole
- C. Propylthiouracil
- D. Prednisone
Correct answer: B
Rationale: Methimazole is the correct answer. It is commonly used to manage hyperthyroidism by inhibiting the production of thyroid hormones. Levothyroxine (Choice A) is actually a medication used to treat hypothyroidism by supplementing thyroid hormones. Propylthiouracil (Choice C) is another anti-thyroid medication used in the management of hyperthyroidism. Prednisone (Choice D) is a corticosteroid and is not typically used in the treatment of hyperthyroidism.
3. A client is receiving a new prescription for enoxaparin. Which of the following instructions should the nurse include?
- A. Rub the injection site after administration.
- B. Pinch the skin while administering the injection.
- C. Aspirate before administering the medication.
- D. Avoid taking aspirin while using this medication.
Correct answer: D
Rationale: The correct answer is D: 'Avoid taking aspirin while using this medication.' Enoxaparin is an anticoagulant medication, and taking aspirin concurrently can increase the risk of bleeding. Choices A, B, and C are incorrect. A nurse should not instruct the client to rub the injection site after administration as it may cause irritation. Pinching the skin while administering the injection is not recommended for enoxaparin injections. Aspirating before administering the medication is also unnecessary as enoxaparin is administered subcutaneously, not intramuscularly.
4. What is the priority nursing intervention for a patient experiencing an acute asthma attack?
- A. Administer bronchodilators
- B. Monitor oxygen saturation
- C. Provide supplemental oxygen
- D. Start IV fluids
Correct answer: A
Rationale: The correct answer is to administer bronchodilators. In an acute asthma attack, the priority is to open the airways and improve airflow. Bronchodilators like albuterol are crucial in providing immediate relief to the patient. Monitoring oxygen saturation (choice B) is important but administering bronchodilators takes precedence in managing the acute attack. Providing supplemental oxygen (choice C) may be necessary but addressing the airway obstruction with bronchodilators is the priority. Starting IV fluids (choice D) is not the priority in an acute asthma attack unless specifically indicated for other reasons such as dehydration.
5. A client with heart failure is being taught about dietary modifications by a nurse. Which of the following client statements indicates an understanding of the teaching?
- A. I will increase my intake of canned vegetables.
- B. I will limit my daily sodium intake to 2 grams.
- C. I will increase my intake of whole grains.
- D. I will reduce my intake of processed meats.
Correct answer: D
Rationale: The correct answer is 'D: I will reduce my intake of processed meats.' This choice indicates an understanding of the teaching because processed meats are high in sodium, which can worsen heart failure due to fluid retention. Choices A, B, and C do not directly address the issue of reducing sodium intake, which is crucial for clients with heart failure. Increasing canned vegetable intake (A) may not always be advisable due to potential high sodium content in canned products. Limiting sodium intake to 2 grams daily (B) is a good practice, but it's more specific to sodium restriction rather than addressing the source of sodium like processed meats. Increasing whole grains (C) is generally beneficial but does not directly relate to reducing sodium intake in heart failure clients.
