1. A client with a history of atrial fibrillation is prescribed warfarin. The nurse should monitor for which sign of potential bleeding?
- A. Elevated blood pressure
- B. Bruising
- C. Shortness of breath
- D. Nausea and vomiting
Correct answer: B
Rationale: Warfarin is an anticoagulant that increases the risk of bleeding. Bruising is a common sign of potential bleeding in clients taking warfarin. Monitoring for bruising is essential as it can indicate a risk of bleeding that needs further assessment and management. Elevated blood pressure, shortness of breath, nausea, and vomiting are not direct signs of potential bleeding associated with warfarin therapy.
2. A client with a history of heart failure is prescribed digoxin. The nurse should monitor for which potential side effect?
- A. Bradycardia
- B. Tachycardia
- C. Hypertension
- D. Hypotension
Correct answer: A
Rationale: Digoxin, a medication commonly prescribed for heart failure, can lead to bradycardia, characterized by a slow heart rate. Monitoring for bradycardia is crucial to detect and manage this potential side effect early on to prevent complications such as arrhythmias or decreased cardiac output. Tachycardia (choice B) is not typically associated with digoxin use. Hypertension (choice C) and hypotension (choice D) are also not common side effects of digoxin.
3. What information should the practical nurse provide to a female client who started taking an oral sulfonamide for a urinary tract infection the previous day and reports slight anorexia, while also experiencing urinary frequency?
- A. Take the medication with an antacid instead of cranberry juice to reduce the anorexia.
- B. Continue to take the medication with a sip of cranberry juice, restricting fluids until the frequency is controlled.
- C. Continue to drink cranberry juice, but take the medicine on an empty stomach with a full glass of water.
- D. Take the medication with a spoonful of ice cream or applesauce and avoid drinking cranberry juice.
Correct answer: C
Rationale: The practical nurse should advise the client to take sulfonamides with a full glass of water to help prevent crystalluria. It is essential to take the medication on an empty stomach, ideally 1 hour before eating or 2 hours after eating to maximize its absorption and effectiveness. Continuing to drink cranberry juice is beneficial, but it is important to take the medicine separately to enhance its therapeutic action.
4. A client who takes metformin for diabetes mellitus type 2 is nothing by mouth (NPO) for surgery. What pre-op prescription should the practical nurse (PN) anticipate for this client's glucose management?
- A. NPO except for metformin and regular snacks
- B. NPO except for oral antidiabetic agent
- C. Novolin-N insulin subcutaneously twice daily
- D. Regular insulin subcutaneously per sliding scale
Correct answer: D
Rationale: When a client taking metformin for diabetes mellitus type 2 is NPO for surgery, it is crucial to manage their glucose levels effectively. The best approach in this situation is to prescribe regular insulin subcutaneously according to a sliding scale based on the client's blood glucose levels. This method allows for precise adjustment of insulin doses to maintain blood glucose within the target range while the client is unable to take oral medications. Choices A and B are incorrect because metformin is typically held when a client is NPO, and oral antidiabetic agents may not provide sufficient glucose control. Choice C is incorrect as Novolin-N insulin given twice daily may not offer the flexibility needed for glucose management in a surgical setting where the client's intake is restricted.
5. A client diagnosed with angina has been prescribed nitrate isosorbide dinitrate. Which instruction should the practical nurse reinforce in this client's teaching?
- A. Discontinue the medication if dizziness occurs.
- B. Avoid getting up quickly. Always rise slowly.
- C. Take the medication with or without food.
- D. Increase your intake of potassium-rich foods.
Correct answer: B
Rationale: The correct instruction that the practical nurse should reinforce with a client prescribed nitrate isosorbide dinitrate is to avoid getting up quickly and to rise slowly. Nitrates can cause orthostatic hypotension, a sudden drop in blood pressure when changing positions. By rising slowly, the client can prevent the occurrence of orthostatic hypotension and its associated symptoms. Choices A, C, and D are incorrect because discontinuing the medication without consulting a healthcare provider can be dangerous, taking the medication with or without food does not impact its effectiveness, and increasing potassium intake is not directly related to the use of nitrate isosorbide dinitrate.
