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 practical nurse (PN) is providing education to a client who is starting therapy with metformin for type 2 diabetes. What side effect should the client be instructed to report to the healthcare provider?
- A. Weight gain
- B. Hypoglycemia
- C. Muscle pain
- D. Nausea
Correct answer: D
Rationale: The correct answer is 'Nausea.' Nausea is a common side effect of metformin, especially when the medication is first started. It is essential for the client to report persistent or severe nausea to the healthcare provider for further evaluation and management. Weight gain (Choice A) is not a typical side effect of metformin; in fact, metformin is associated with weight loss or weight neutrality. Hypoglycemia (Choice B) is a potential side effect of some diabetes medications, but metformin does not typically cause hypoglycemia. Muscle pain (Choice C) is not a common side effect of metformin; it is more commonly associated with other medications like statins.
3. The practical nurse administers lactulose to a client. Which client outcome would indicate a therapeutic response?
- A. An increase in urine output
- B. Two to three soft stools per day
- C. Absence of nausea
- D. Decreased serum potassium
Correct answer: B
Rationale: Lactulose is a type of laxative that works by preventing the absorption of ammonia in the colon, leading to increased water absorption in the stool and softening of the stool. The therapeutic response to lactulose is indicated by the passage of two to three soft stools per day, showing that the medication is effectively promoting bowel movements.
4. What is the primary nursing intervention that the practical nurse should perform before administering ampicillin to a client diagnosed with a urinary tract infection?
- A. Obtain a clean-catch urine specimen.
- B. Assess the urine pH for acidity.
- C. Insert an indwelling catheter.
- D. Assess for complaints of dysuria.
Correct answer: A
Rationale: The correct answer is to obtain a clean-catch urine specimen. Before administering ampicillin to a client with a urinary tract infection, it is crucial to collect a urine specimen to determine the causative organism and evaluate the effectiveness of pharmacological therapy. Assessing the urine pH for acidity (choice B) is not the primary intervention needed before administering ampicillin. Inserting an indwelling catheter (choice C) is invasive and not necessary unless indicated for specific reasons. Assessing for complaints of dysuria (choice D) is important but does not take precedence over obtaining a urine specimen for proper diagnosis and treatment.
5. A client arrives at the emergency department experiencing diabetic ketoacidosis (DKA). The healthcare provider prescribes an insulin intravenous drip. Which type of insulin should the nurse locate for the registered nurse to mix into the intravenous fluids?
- A. Isophane
- B. Glargine
- C. Regular
- D. Detemir
Correct answer: C
Rationale: The correct insulin type for the nurse to mix into the intravenous fluids is regular insulin. In the scenario of diabetic ketoacidosis (DKA), rapid reduction of blood glucose levels is crucial. Regular insulin has a fast onset of action, making it suitable for intravenous administration to address the high blood sugar levels seen in DKA. Isophane, Glargine, and Detemir are not appropriate choices for intravenous administration in this emergency situation as they are intermediate-acting or long-acting insulins which do not provide the rapid response needed in DKA.
