The nurse instructing a client with chronic pancreatitis about measures to prevent its exacerbation should provide which information? Select all that apply.
- A. Eat bland foods.
- B. Avoid alcohol ingestion.
- C. Avoid cigarette smoking.
- D. Avoid caffeinated beverages.
- E. Eat small meals and snacks high in calories.
- F. Eat high-fat, low-protein, high-carbohydrate meals.
Correct Answer: A,B,C,D,E
Rationale: Chronic pancreatitis is a progressive, destructive disease of the pancreas, characterized by remissions and exacerbations (recurrence). Measures to prevent an exacerbation include eating bland, low-fat, high-protein, moderate-carbohydrate meals; avoiding alcohol ingestion, nicotine, and caffeinated beverages; eating small meals and snacks high in calories; and avoiding gastric stimulants such as spices.

A client at risk for respiratory failure is receiving oxygen via nasal cannula at 6 L per minute. Arterial blood gas (ABG) results indicate pH 7.29, PcO2 49 mm Hg, Po2 58 mm Hg, and HCO3 18 mEq/L. What intervention should the nurse anticipate that the primary health care provider will prescribe for respiratory support for this client?
- A. Intubating for mechanical ventilation
- B. Keeping the oxygen at 6 L per minute via nasal cannula
- C. Lowering the oxygen to 4 L per minute via nasal cannula
- D. Adding a partial rebreather mask to the current prescription
Correct Answer: A
Rationale: If respiratory failure occurs and supplemental oxygen cannot maintain acceptable PaO2 and PaCO2 levels, endotracheal intubation and mechanical ventilation are necessary. The client is exhibiting respiratory acidosis, metabolic acidosis, and hypoxemia. Lowering or keeping the oxygen at the same liter flow will not improve the client's condition. A partial rebreather mask will raise CO2 levels even further.
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.
- B. You are having a severe problem and will probably be rehospitalized
- 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.
Correct Answer: A
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 sends a sputum specimen to the laboratory for culture from a client with suspected active tuberculosis (TB). The results report that Mycobacterium tuberculosis is cultured. How should the nurse correctly analyze these results?
- A. The results are positive for active tuberculosis.
- B. The results indicate a less virulent strain of tuberculosis.
- C. The results are inconclusive until a repeat sputum specimen is sent.
- D. The results are unreliable unless the client has also had a positive tuberculin skin test (TST).
Correct Answer: A
Rationale: Culture of Mycobacterium tuberculosis from sputum or other body secretions or tissue confirms the diagnosis of active tuberculosis.
A client receiving total parenteral nutrition (TPN) via a central venous catheter (CVC) is scheduled to receive an intravenous (IV) antibiotic. Which intervention should the nurse implement before administering the antibiotic?
- A. Turn off the TPN for 30 minutes.
- B. Ensure a separate IV access route.
- C. Flush the CVC with normal saline.
- D. Check for compatibility with TPN.
Correct Answer: B
Rationale: The TPN line is used only for the administration of the TPN solution to prevent crystallization in the CVC tubing and disruption of the TPN infusion. Any other IV medication must be administered through a separate IV access site, including a separate infusion port of the CVC catheter. Therefore, options 1, 3, and 4 are incorrect actions.
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.
