- A. Seizures
- B. Dry mouth
- C. Edema
- D. Serotonin syndrome

It is important for individuals taking iron supplements to follow recommended dosages to prevent adverse effects.
2. A client has been prescribed Prednisone for an inflammatory condition and is receiving discharge teaching from a nurse. Which of the following instructions should the nurse include?
- A. Take this medication on an empty stomach.
- B. Avoid alcohol while taking this medication.
- C. Monitor your blood pressure regularly.
- D. Take this medication in the morning to prevent insomnia.
Correct answer: D
Rationale: The correct answer is to take Prednisone in the morning to prevent insomnia. Prednisone can cause insomnia as a side effect, so taking it in the morning can help minimize this issue. It is important to follow the healthcare provider's instructions regarding the timing of Prednisone administration to optimize its effectiveness and minimize adverse effects.
3. A client in a critical care unit is postoperative following a right pneumonectomy. After extubation from the ventilator, in which of the following positions should the client be placed?
- A. Prone
- B. On the nonoperative side
- C. Sims'
- D. Semi-Fowler's
Correct answer: D
Rationale: After a pneumonectomy, positioning the client in a semi-Fowler's position is crucial for optimal ventilation. This position helps improve lung expansion on the remaining side, facilitating better oxygenation and preventing complications like atelectasis. Placing the client prone, on the nonoperative side, or in Sims' position would not provide the same respiratory benefits post-pneumonectomy.
4. Which of the following drugs has a therapeutic effect that prevents thromboembolic events?
- A. Warfarin

- A. Decreasing intestinal glucose absorption
- B. Increasing sensitivity to insulin
- C. Decreasing hepatic glucose production
