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 caring for a client who has osteoarthritis. Which of the following actions should the nurse take?
- A. Apply heat to inflamed joints
- B. Provide passive range-of-motion exercises
- C. Encourage prolonged use of NSAIDs
- D. Apply cold packs to the joints
Correct answer: A
Rationale: Corrected Rationale: Applying heat to inflamed joints can help relieve pain in clients with osteoarthritis. Heat therapy can help improve blood circulation, relax muscles, and reduce stiffness. Choice B, providing passive range-of-motion exercises, may be beneficial for joint mobility but is not the first-line intervention for pain relief in osteoarthritis. Choice C, encouraging prolonged use of NSAIDs, should be done cautiously due to potential side effects and should be guided by a healthcare provider. Choice D, applying cold packs to the joints, is not recommended for osteoarthritis as cold therapy can worsen stiffness and discomfort in this condition.
3. What is the best intervention for a patient experiencing severe hypoglycemia?
- A. Administer IV dextrose
- B. Administer oral glucose
- C. Monitor blood sugar levels
- D. Recheck blood sugar in 15 minutes
Correct answer: A
Rationale: The best intervention for a patient experiencing severe hypoglycemia is to administer IV dextrose. This intervention is necessary to rapidly raise blood sugar levels in critical situations. Administering oral glucose may not be effective in severe cases as the patient may be unable to consume it. Monitoring blood sugar levels and rechecking blood sugar in 15 minutes are important steps but not the initial best intervention for severe hypoglycemia.
4. What is the appropriate action for a patient experiencing chest pain?
- A. Administer aspirin
- B. Reposition the patient
- C. Check oxygen saturation
- D. Prepare for surgery
Correct answer: A
Rationale: The correct action for a patient experiencing chest pain is to administer aspirin. Aspirin helps reduce the risk of clot formation in patients with chest pain, as it has antiplatelet effects. Repositioning the patient may not address the underlying cause of the chest pain. Checking oxygen saturation is important but not the initial priority in this scenario. Surgery is not typically the first-line treatment for chest pain without further assessment and diagnostic procedures.
5. A nurse is reviewing the laboratory results for a client who has Cushing's disease. The nurse should expect the client to have an increase in which of the following laboratory values?
- A. Serum glucose level.
- B. Serum calcium level.
- C. Lymphocyte count.
- D. Serum potassium level.
Correct answer: A
Rationale: The correct answer is A: Serum glucose level. In Cushing's disease, elevated cortisol levels lead to increased gluconeogenesis, insulin resistance, and breakdown of proteins and fats, resulting in elevated blood glucose levels. This is known as hyperglycemia. The other options, including serum calcium level (choice B), lymphocyte count (choice C), and serum potassium level (choice D), are not typically affected by Cushing's disease. Therefore, they are incorrect choices.
