1. A client with a diagnosis of bipolar disorder is prescribed lamotrigine. The nurse should monitor for which potential adverse effect?
- A. Rash
- B. Tremors
- C. Hair loss
- D. Weight gain
Correct answer: A
Rationale: The correct answer is A: Rash. Lamotrigine can cause a rash, which may indicate a serious adverse effect like Stevens-Johnson syndrome. Monitoring for a rash is crucial in clients taking lamotrigine to promptly address any potential severe reactions.
2. A client with chronic kidney disease is prescribed cinacalcet. The nurse should monitor for which potential side effect?
- A. Hypocalcemia
- B. Hypercalcemia
- C. Hyperkalemia
- D. Hyperphosphatemia
Correct answer: A
Rationale: Corrected Rationale: Cinacalcet is a medication that can lower calcium levels, leading to hypocalcemia. Monitoring for signs of low calcium levels such as muscle cramps, tingling sensations, and abnormal heart rhythms is crucial to prevent complications in clients with chronic kidney disease.\nIncorrect Choices Rationale: B) Hypercalcemia is the opposite effect of cinacalcet; C) Hyperkalemia and D) Hyperphosphatemia are not typically associated with cinacalcet use.
3. 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.
4. A client has a prescription for heparin 1,000 units IV STAT. Several pre-filled syringes of low molecular weight heparin are available in the client's medication drawer. Which action should the nurse implement?
- A. Dilute the available heparin in 250ml of normal saline solution prior to IV administration
- B. Advise the pharmacy on the need to deliver a vial of heparin to the nursing unit immediately
- C. Calculate and administer the equivalent dose of the available low molecular weight heparin
- D. Request a prescription to change the route of administration and use the available heparin
Correct answer: B
Rationale: In this scenario, the nurse should contact the pharmacy to obtain the correct heparin formulation as the prescription calls for heparin 1,000 units IV STAT. Low molecular weight heparin is not the same as unfractionated heparin, and therefore, the nurse should not administer the available low molecular weight heparin without first obtaining the correct medication. Diluting the available heparin, calculating an equivalent dose, or changing the route of administration would not address the discrepancy between the prescribed heparin and the available low molecular weight heparin.
5. A client with a diagnosis of schizophrenia is prescribed aripiprazole. The nurse should monitor the client for which potential side effect?
- A. Weight gain
- B. Dry mouth
- C. Headache
- D. Increased appetite
Correct answer: A
Rationale: Aripiprazole is known to cause weight gain in patients, so monitoring for changes in weight is essential to assess for this potential side effect and intervene accordingly.
