1. A client with type 2 diabetes is prescribed metformin. What instruction should the practical nurse (PN) include in the client's teaching plan?
- A. Take the medication with meals to decrease gastrointestinal upset.
- B. Take the medication with a full glass of water.
- C. Avoid alcohol while taking the medication.
- D. Take the medication with meals to increase absorption.
Correct answer: B
Rationale: The correct instruction for a client prescribed metformin is to take the medication with a full glass of water. This helps ensure proper ingestion and absorption of the medication. While taking metformin with meals can help reduce gastrointestinal side effects, the primary focus should be on adequate hydration and absorption by taking it with water. Avoiding alcohol while taking metformin is also important as alcohol can increase the risk of lactic acidosis when combined with metformin. Taking the medication with meals to increase absorption is incorrect as metformin should be taken with food to reduce gastrointestinal upset, not to increase absorption.
2. A client taking long-term steroids also has ranitidine prescribed. The nurse provides which explanation as to why these drugs are given together?
- A. Ranitidine reduces the risk of ulcers associated with steroids.
- B. Ranitidine decreases the risk of infection associated with steroids.
- C. Ranitidine decreases blood sugar elevations associated with steroids.
- D. Ranitidine reduces sodium retention associated with steroid usage.
Correct answer: A
Rationale: The correct answer is A. Ranitidine is prescribed with long-term steroids to reduce the risk of ulcers associated with steroid therapy. Although steroids can increase the risk of ulcers due to their effect on the gastrointestinal system, ranitidine works by reducing stomach acid production, thus helping to prevent ulcer formation. Choices B, C, and D are incorrect as ranitidine is not given to decrease the risk of infection, reduce blood sugar elevations, or reduce sodium retention associated with steroid usage.
3. A client is prescribed diazepam for muscle spasms. What instruction should the nurse include in the client's teaching plan?
- A. Avoid drinking alcohol
- B. Take with food to avoid gastrointestinal upset
- C. Increase fluid intake
- D. Take medication with grapefruit juice
Correct answer: A
Rationale: The correct instruction for a client prescribed diazepam for muscle spasms is to avoid drinking alcohol. Diazepam can cause drowsiness and enhance the effects of alcohol, leading to increased sedation and impaired cognitive function. Clients should be advised to avoid alcohol consumption while taking diazepam to prevent these adverse effects and ensure their safety.
4. A client has been prescribed losartan. Which change in data indicates to the practical nurse (PN) that the desired effect of this medication has been achieved?
- A. Dependent edema reduced from +3 to +1.
- B. Serum HDL increased from 35 to 55 mg/dL.
- C. Pulse rate reduced from 150 to 90 beats/min.
- D. Blood pressure reduced from 160/90 to 130/80 mm Hg.
Correct answer: D
Rationale: The correct answer is D. Losartan is prescribed for the treatment of hypertension. The desired effect of losartan is to reduce blood pressure. Therefore, a reduction in blood pressure from 160/90 to 130/80 mm Hg indicates that the desired effect of the medication has been achieved. Choices A, B, and C are not specific effects of losartan and do not directly relate to the expected outcomes of this medication. Dependent edema, serum HDL levels, and pulse rate are not typically influenced by losartan, making choices A, B, and C incorrect.
5. A client with bipolar disorder is taking lithium. Which client assessment data would indicate a potential adverse effect of lithium therapy?
- A. Increased appetite
- B. Dry mouth and increased thirst
- C. Tremors and polyuria
- D. Constipation
Correct answer: B
Rationale: When assessing a client taking lithium, dry mouth and increased thirst are indicators of potential adverse effects. Lithium can lead to nephrogenic diabetes insipidus, causing polyuria and subsequent increased thirst due to impaired water reabsorption in the kidneys. Tremors can also be a sign of lithium toxicity. Monitoring and recognizing these symptoms are crucial in managing lithium therapy and preventing further complications.
