1. A client with chronic kidney disease is prescribed sevelamer carbonate. The nurse should monitor for which potential side effect?
- A. Hypercalcemia
- B. Hypocalcemia
- C. Hyperkalemia
- D. Hypokalemia
Correct answer: A
Rationale: When a client with chronic kidney disease is prescribed sevelamer carbonate, the nurse should monitor for hypercalcemia as a potential side effect. Sevelamer carbonate can bind to dietary calcium and impair its absorption, potentially leading to elevated calcium levels in the blood. Monitoring calcium levels is crucial to detect and manage hypercalcemia promptly. Hypocalcemia (choice B) is incorrect because sevelamer carbonate's action is more likely to cause elevated calcium levels. Hyperkalemia (choice C) and hypokalemia (choice D) are related to potassium levels and are not typically associated with sevelamer carbonate use.
2. A client with a diagnosis of generalized anxiety disorder is prescribed alprazolam. The nurse should instruct the client that this medication may have which potential side effect?
- A. Drowsiness
- B. Dry mouth
- C. Nausea
- D. Headache
Correct answer: A
Rationale: The correct answer is A: Drowsiness. Alprazolam, a medication commonly used to treat anxiety disorders, can cause drowsiness as a common side effect. Clients should be advised not to drive or operate heavy machinery until they know how the medication affects them to ensure their safety.
3. A client with a diagnosis of generalized anxiety disorder is prescribed paroxetine. The nurse should instruct the client that this medication may have which potential side effect?
- A. Drowsiness
- B. Dry mouth
- C. Nausea
- D. Headache
Correct answer: A
Rationale: The correct answer is A: Drowsiness. Paroxetine, used for generalized anxiety disorder, can cause drowsiness. Clients should be advised not to drive or operate heavy machinery until they know how the medication affects them. Dry mouth, nausea, and headache are potential side effects of other medications but are not commonly associated with paroxetine. Drowsiness is a common side effect for paroxetine and can impact a client's ability to perform tasks that require alertness.
4. 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.
5. When administering medications to a group of clients, which client should the nurse closely monitor for the development of acute kidney injury (AKI)?
- A. Lorazepam
- B. Sucralfate
- C. Digoxin
- D. Vancomycin
Correct answer: D
Rationale: Vancomycin is known to be nephrotoxic, which means it can cause damage to the kidneys. Therefore, clients receiving Vancomycin should be closely monitored for signs and symptoms of acute kidney injury (AKI) to ensure early detection and intervention if necessary. Lorazepam, Sucralfate, and Digoxin do not typically cause acute kidney injury, so they are not the priority for monitoring in this scenario.
