Question 1 of 5
Which of the following measures should the nurse focus on for the client with esophageal varices?
Correct Answer: A
Rationale: In managing a client with esophageal varices, the nurse's primary focus should be on recognizing hemorrhage (Option A) as it is a life-threatening complication associated with this condition. Esophageal varices are fragile, dilated blood vessels in the esophagus that can easily rupture, leading to severe bleeding. Early detection of hemorrhage is crucial for prompt intervention to prevent shock and potential death. Controlling blood pressure (Option B) is not directly related to managing esophageal varices. While hypertension can exacerbate bleeding, it is not the priority in this context. Encouraging nutritional intake (Option C) is important for overall health but is not the immediate concern when dealing with a client at risk for hemorrhage. Teaching the client about varices (Option D) is important for long-term management but does not address the acute emergency of hemorrhage. Educationally, understanding the critical nature of recognizing hemorrhage in clients with esophageal varices reinforces the importance of assessment skills, quick decision-making, and prioritization in nursing practice. By focusing on the correct measure, nurses can provide timely and effective care to prevent adverse outcomes in these high-risk patients.
Question 2 of 5
Which of the following best describes the method of action of medications, such as ranitidine (Zantac), which are used in the treatment of peptic ulcer disease?
Correct Answer: B
Rationale: In the treatment of peptic ulcer disease, medications like ranitidine (Zantac) work by reducing acid secretions. This is the correct answer because drugs like ranitidine belong to a class of medications called H2-receptor antagonists, which inhibit the action of histamine on the parietal cells in the stomach. By blocking histamine, these medications reduce the production of stomach acid, thereby helping to heal and prevent ulcers. Option A, neutralizing acid, is incorrect because medications like ranitidine do not directly neutralize the acid already present in the stomach; instead, they reduce its production. Option C, stimulating gastrin release, is incorrect as increasing gastrin levels would lead to more acid production, exacerbating the ulcer condition. Option D, protecting the mucosal barrier, is incorrect because while it is important in ulcer management, ranitidine specifically targets acid reduction rather than directly protecting the mucosal barrier. In an educational context, understanding the mechanism of action of medications used in gastrointestinal disorders is crucial for nurses to provide safe and effective care to patients with peptic ulcer disease. Knowing how ranitidine works helps nurses to administer the medication correctly, monitor for therapeutic effects, and educate patients on the importance of compliance with their treatment regimen to promote healing and prevent ulcer recurrence.
Question 3 of 5
The hospitalized client with GERD is complaining of chest discomfort that feels like heartburn following a meal. After administering an ordered antacid, the nurse encourages the client to lie in which of the following positions?
Correct Answer: C
Rationale: In this scenario, the correct answer is C) On the left side with the head of the bed elevated 30 degrees. This position helps prevent reflux of gastric contents into the esophagus, as lying on the left side promotes the emptying of the stomach and keeps the esophagus above the level of gastric contents. This can help alleviate symptoms of GERD, such as heartburn. Option A) Supine with the head of the bed flat would not be ideal for a client with GERD as it can worsen symptoms by allowing gastric contents to flow back into the esophagus due to gravity. Option B) On the stomach with the head flat is also not recommended as it can increase pressure on the stomach, leading to reflux. Educationally, it is important for nursing students to understand the rationale behind positioning in managing GERD to provide optimal care for their patients. Understanding the physiological basis for interventions helps students make informed clinical decisions and improve patient outcomes. It also reinforces the importance of individualized care based on the patient's specific needs and conditions.
Question 4 of 5
The nurse is caring for a client following a Billroth II procedure. On review of the post-operative orders, which of the following, if prescribed, would the nurse question and verify?
Correct Answer: A
Rationale: In the case of a client following a Billroth II procedure, the correct answer to question and verify among the given options is A) Irrigating the nasogastric tube. This is because after a Billroth II procedure, the client has a gastrojejunostomy where gastric contents are diverted to the jejunum, bypassing the duodenum. Therefore, irrigating the nasogastric tube could introduce contents directly into the small intestine, leading to complications like dumping syndrome or disruption of the healing process. Option B) Coughing and deep breathing exercises, Option C) Leg exercises, and Option D) Early ambulation are appropriate post-operative care interventions for a client following a Billroth II procedure. These interventions help prevent complications such as pneumonia, thrombosis, and muscle weakness associated with immobility. They promote respiratory function, circulation, and overall mobility, aiding in the client's recovery and preventing post-operative complications. Educationally, understanding the rationale behind post-operative care interventions following specific surgical procedures is crucial for nurses to provide safe and effective care to their clients. It requires knowledge of the surgical procedure, its implications on the body, and how nursing interventions can support the client's recovery process while preventing complications. This case highlights the importance of critical thinking and clinical reasoning in nursing practice to ensure optimal patient outcomes.
Question 5 of 5
The nurse is providing discharge instructions to a client following gastrectomy. Which measure will the nurse instruct the client to follow to assist in preventing dumping syndrome?
Correct Answer: B
Rationale: In the context of a client post-gastrectomy to prevent dumping syndrome, option B, limiting fluids taken with meals, is the correct measure. Dumping syndrome occurs when food moves too quickly from the stomach to the small intestine, causing symptoms like cramping, diarrhea, and palpitations. Limiting fluids helps slow down gastric emptying, reducing the risk of dumping syndrome. Option A, eating high-carbohydrate foods, is incorrect as these can exacerbate dumping syndrome by rapidly increasing blood sugar levels, leading to a surge in insulin release and subsequent hypoglycemia. Option C, ambulating following a meal, and option D, sitting in a high-Fowlers position during meals, are not directly related to preventing dumping syndrome. From an educational perspective, understanding the pathophysiology of dumping syndrome and the rationale behind each measure is crucial for nurses to provide accurate discharge instructions and ensure optimal patient outcomes. It is essential for nurses to have a solid understanding of postoperative care guidelines to support patients effectively in their recovery process.
