1. A client with chronic kidney disease is prescribed lanthanum carbonate. The nurse should monitor for which potential side effect?
- A. Hypercalcemia
- B. Hypocalcemia
- C. Hyperkalemia
- D. Hypokalemia
Correct answer: A
Rationale: Lanthanum carbonate is prescribed in chronic kidney disease to bind dietary phosphorus in the gastrointestinal tract. This action can lead to decreased phosphorus absorption and potential hypercalcemia due to the increased serum calcium levels. Therefore, the nurse should monitor the client for signs and symptoms of hypercalcemia, such as confusion, fatigue, and muscle weakness. Choices B, C, and D are incorrect as lanthanum carbonate's mechanism of action does not lead to hypocalcemia, hyperkalemia, or hypokalemia.
2. How should the healthcare provider schedule the administering of propylthiouracil (PTU)?
- A. Offer both drugs together with a meal
- B. Give parental dose once every 24 hours
- C. Schedule both medications at bedtime
- D. Administer iodine one hour before PTU
Correct answer: D
Rationale: Administering iodine one hour before PTU is crucial to ensure proper absorption and effectiveness of PTU. This timing helps optimize the therapeutic benefits of PTU by allowing it to be absorbed efficiently without interference from iodine, ultimately leading to better treatment outcomes for the patient. Choices A, B, and C are incorrect because offering both drugs together with a meal, giving parental dose once every 24 hours, and scheduling both medications at bedtime do not address the specific timing requirement of administering iodine before PTU for optimal absorption.
3. A client with a diagnosis of schizophrenia is prescribed clozapine. The nurse should monitor the client for which potential side effect?
- A. Agranulocytosis
- B. Dry mouth
- C. Weight gain
- D. Hypersalivation
Correct answer: A
Rationale: The correct answer is Agranulocytosis. Clozapine is known to potentially cause agranulocytosis, a serious condition characterized by a dangerously low white blood cell count. Monitoring white blood cell counts is crucial to detect this side effect early and prevent complications. Choices B, C, and D are incorrect because dry mouth, weight gain, and hypersalivation are not typically associated with clozapine use. While dry mouth can be a common side effect of some antipsychotic medications, it is not specifically linked to clozapine. Weight gain can occur with certain antipsychotics, but clozapine is more commonly associated with metabolic side effects. Hypersalivation is not a common side effect of clozapine.
4. A client who is newly diagnosed with erosive esophagitis secondary to GERD experiences symptoms after taking lansoprazole PO for one full week. Which actions should the nurse take?
- A. Confirm that the client is taking the medication correctly
- B. Auscultate the client's bowel sounds and assess the apical pulse
- C. Advise the client that healing typically takes several weeks
- D. Notify the healthcare provider to consider a higher dose
Correct answer: C
Rationale: The correct action for the nurse to take in this situation is to advise the client that healing from erosive esophagitis typically takes several weeks. Providing this information helps manage the client's expectations and anxiety about treatment effectiveness. It is not necessary to confirm medication timing, assess bowel sounds, or measure the apical pulse at this point. Since symptoms persist after one week of lansoprazole, it may not be appropriate to immediately escalate to a higher dose without further assessment or guidance from the healthcare provider. Auscultating bowel sounds and assessing the apical pulse are not relevant to the client's symptoms related to erosive esophagitis and GERD.
5. While a client is receiving the medication haloperidol, which client data would indicate to the practical nurse that the medication is therapeutic?
- A. The client has maintained consistent weight loss of 2 pounds per week.
- B. The client has demonstrated a decrease in paranoid behaviors.
- C. The client's blood pressure has remained within normal limits.
- D. The client's fasting blood glucose has remained below 120 mg/dL.
Correct answer: B
Rationale: When a client is taking haloperidol, a therapeutic response involves a decrease in symptoms such as paranoia, hallucinations, delusions, and emotional excitement. These improvements indicate that the medication is effectively managing the client's condition. Monitoring for a reduction in paranoid behaviors helps the practical nurse assess the medication's effectiveness in addressing the client's psychiatric symptoms.
