Which of the following conditions can cause a hiatal hernia?
- A.
Increased intrathoracic pressure
- B.
Weakness of the esophageal muscle
- C.
Increased esophageal muscle pressure
- D.
Weakness of the diaphragmatic muscle
Correct Answer
D. Weakness of the diaphragmatic muscleExplanation
A hiatal hernia is caused by weakness of the diaphragmatic muscle and increased intra-abdominal—not intrathoracic—pressure. This weakness allows the stomach to slide into the esophagus. The esophageal supports weaken. but esophageal muscle weakness or increased esophageal muscle pressure isn’t a factor in hiatal hernia.Rate this question:

Risk factors for the development of hiatal hernias are those that lead to increased abdominal pressure. Which of the following complications can cause increased abdominal pressure?
- A.
Obesity
- B.
Volvulus
- C.
Constipation
- D.
Intestinal obstruction

Which of the following tests can be performed to diagnose a hiatal hernia?
- A.
Colonoscopy
- B.
Lower GI series
- C.
Barium swallow
- D.
Abdominal x-rays

Which of the following measures should the nurse focus on for the client with esophageal varices?
- A.
Recognizing hemorrhage
- B.
Controlling blood pressure

Teaching the client about varices
Correct Answer
A. Recognizing hemorrhageExplanation
Recognizing the rupture of esophageal varices. or hemorrhage. is the focus of nursing care because the client could succumb to this quickly. Controlling blood pressure is also important because it helps reduce the risk of variceal rupture. It is also important to teach the client what varices are and what foods he should avoid such as spicy foods.Rate this question:

Which of the following tests can be used to diagnose ulcers?
- A.
Abdominal x-ray
- B.
Barium swallow
- C.
Computed tomography (CT) scan
- D.
Esophagogastroduodenoscopy (EGD)
Correct Answer
D. Esophagogastroduodenoscopy (EGD)Explanation
The EGD can visualize the entire upper GI tract as well as allow for tissue specimens and electrocautery if needed. The barium swallow could locate a gastric ulcer. A CT scan and an abdominal x-ray aren’t useful in the diagnosis of an ulcer.Rate this question:

Coughing a deep breathing exercises
- C.
Leg exercises
- D.
Early ambulation
Correct Answer
A. Irrigating the nasogastric tubeExplanation
In a Billroth II procedure the proximal remnant of the stomach is anastomosed to the proximal jejunum. Patency of the NG tube is critical for preventing the retention of gastric secretions. The nurse should never irrigate or reposition the gastric tube after gastric surgery. unless specifically ordered by the physician. In this situation. the nurse would clarify the order.Rate this question:
