During a follow-up visit 2 weeks after pneumonectomy, the client reports numbness and tenderness at the surgical site. Which statement should the nurse make to accurately address the client's concerns?
- A. This is not likely to be permanent, but may last for some months.

- C. This is probably caused by permanent nerve damage as a result of surgery.
- D. This is often the first sign of a wound infection; I will check your temperature.

Rationale: Clients who undergo pneumonectomy or other surgical procedures may experience numbness, altered sensation, or tenderness in the area that surrounds the incision. These sensations may last for months. It is not considered to be a severe problem and is not indicative of a wound infection.
The nurse is checking postoperative prescriptions and planning care for a 110-pound child after spinal fusion. Morphine sulfate, 8 mg subcutaneously every 4 hours PRN for pain, is prescribed. The pediatric medication reference states that the safe dose is 0.1 to 0.2 mg/kg/dose every 3 to 4 hours. From this information, the nurse determines what about the prescription?
- A. The dose is too low.
- B. The dose is too high.
- C. The dose is within the safe dosage range.
- D. There is not enough information to determine the safe dose.
Correct Answer: C
Rationale: Use the formula to determine the dosage parameters. Convert pounds to kilograms by dividing weight by 2.2. Therefore, 110 lb ÷ 2.2 = 50 kg. Dosage parameters: 0.1 mg/kg/dose × 50 kg = 5 mg; 0.2 mg/kg/dose × 50 kg = 10 mg. Dosage is within the safe dosage range.
A client diagnosed with chronic kidney disease is prescribed epoetin alfa. When discussing measures needed to support this medication therapy, the nurse should include information regarding which supplement?
- A. Iron
- B. Zinc
- C. Calcium
- D. Magnesium
Correct Answer: A
Rationale: Epoetin alfa is a hematopoietic agent used to stimulate red blood cell production in clients with anemia, such as those with chronic kidney disease. Iron supplementation is necessary to support this therapy because adequate iron stores are required for effective erythropoiesis. Without sufficient iron, the effectiveness of epoetin alfa is reduced. Zinc, calcium, and magnesium are not directly related to supporting red blood cell production in this context.
A magnetic resonance imaging (MRI) scan is prescribed for a client with a suspected brain tumor. Which prescription should the nurse anticipate will be prescribed for the client before the procedure?
- A. An opioid
- B. A sedative
- C. A corticosteroid
- D. An antihistamine
Correct Answer: B
Rationale: An MRI scan is a noninvasive diagnostic test that visualizes the body's tissues, structure, and blood flow. For an MRI, the client is positioned on a padded table and moved into a cylinder-shaped scanner. Relaxation techniques, an eye mask, and sedation are used before the procedure to reduce claustrophobic effects; however, because the client must remain very still during the scan, the nurse avoids oversedating the client to ensure client cooperation. There is no useful purpose for administering an opioid, corticosteroid, or antihistamine.
To ensure client safety, which assessment is most important for the nurse to make before advancing a client from liquid to solid food?
- A. Bowel sounds
- B. Chewing ability
- C. Current appetite
- D. Food preferences
Correct Answer: B
Rationale: The nurse needs to assess the client's chewing ability before advancing a client from liquid to solid food. It may be necessary to modify a client's diet to a soft or mechanical chopped diet if the client has difficulty chewing because of the risk of aspiration. Bowel sounds should be present before introducing any diet, including liquids. Appetite will affect the amount of food eaten, but not the type of diet prescribed. Food preferences should be ascertained on admission assessment.
