1. A client with Addison's disease is being admitted for a total hip arthroplasty. The client takes hydrocortisone for Addison's disease. What is the nurse's priority action?
- A. Administering a supplemental dose of hydrocortisone
- B. Instructing the client about coughing and deep breathing
- C. Collecting additional information from the client about his history of Addison's disease
- D. Inserting an indwelling urinary catheter
Correct answer: A
Rationale: The nurse's priority in this situation is to administer a supplemental dose of hydrocortisone. Clients with Addison's disease taking hydrocortisone are at risk of acute adrenal insufficiency during times of stress such as surgery. Administering supplemental doses of hydrocortisone helps prevent acute adrenal insufficiency (adrenal crisis) in these situations, making it the priority action to ensure the client's safety. Instructing the client about coughing and deep breathing is important postoperatively but not the priority at this time. Collecting additional information about the client's history of Addison's disease is important but not the priority action before surgery. Inserting an indwelling urinary catheter is not the priority in this situation.
2. A client is prescribed Diltiazem. Which of the following findings should the nurse monitor?
- A. Tachycardia
- B. Bradycardia
- C. Hypertension
- D. Hyperkalemia
Correct answer: B
Rationale: Diltiazem is a calcium channel blocker that can lead to bradycardia as an adverse effect due to its negative chronotropic and dromotropic effects on the heart. The nurse should monitor the client's heart rate regularly to detect any signs of bradycardia and take appropriate actions if necessary. Tachycardia (Choice A) is not an expected finding with Diltiazem use. Hypertension (Choice C) is actually a condition that Diltiazem is used to treat. Hyperkalemia (Choice D) is not a common adverse effect of Diltiazem.
3. While caring for a client receiving Heparin therapy, which of the following laboratory tests should the nurse monitor to evaluate the effectiveness of the therapy?
- A. PT
- B. INR
- C. aPTT
- D. Platelet count
Correct answer: C
Rationale: The nurse should monitor the aPTT (activated partial thromboplastin time) when caring for a client receiving Heparin therapy. The aPTT reflects the intrinsic pathway of the clotting cascade and is used to monitor the effectiveness of heparin, which primarily affects this pathway by potentiating antithrombin III. Monitoring the aPTT helps ensure that the client's blood is within the therapeutic range to prevent thrombus formation. Choices A, B, and D are incorrect. PT (Prothrombin Time) and INR (International Normalized Ratio) are used to monitor Warfarin therapy, not Heparin. Platelet count is important in assessing for thrombocytopenia but is not a specific indicator of Heparin therapy effectiveness.
4. A client has a new prescription for Digoxin. Which of the following instructions should the nurse include?
- A. Take the medication with food.
- B. Monitor your pulse before taking the medication.
- C. Expect to have an increased appetite.
- D. Discontinue the medication if you feel nauseated.
Correct answer: B
Rationale: When educating a client about Digoxin, it is crucial to instruct them to monitor their pulse before taking the medication. Digoxin can lead to bradycardia, so monitoring the pulse is essential to ensure it is not below 60 beats per minute before taking each dose. If the pulse is low, the client should hold the dose and seek guidance from their healthcare provider. Choices A, C, and D are incorrect. Taking Digoxin with food may affect its absorption, Digoxin is not known to increase appetite, and feeling nauseated does not necessarily indicate the need to discontinue the medication.
5. A client has been prescribed an anticoagulant for atrial fibrillation. Which of the following instructions should the nurse include?
- A. Take the medication with food to prevent nausea.
- B. Avoid activities that may cause injury.
- C. Monitor your heart rate daily before taking the medication.
- D. Avoid alcohol while taking this medication.
Correct answer: B
Rationale: The correct instruction for a client prescribed an anticoagulant for atrial fibrillation is to avoid activities that may cause injury. Anticoagulants increase the risk of bleeding, so it is important to prevent situations that could lead to injury or trauma. Choice A is incorrect because anticoagulants are not typically affected by food intake. Choice C is not necessary for all anticoagulant medications, and heart rate monitoring is more relevant for other conditions. Choice D is not directly related to the action of anticoagulants and is not a priority instruction for this medication.
