Correct Answer: C

Rationale: The correct answer is C. Eating three eggs daily increases cholesterol intake, which could exacerbate atherosclerosis. Omega-3 supplements, cooking with canola oil, and flavoring meat with lemon juice do not significantly impact cholesterol levels compared to consuming three eggs daily. Therefore, the nurse should focus on educating the client to reduce egg consumption to improve cholesterol levels.

Correct Answer: D

Rationale: In this scenario, the client's presentation of acute epigastric pain and vomiting bright red blood indicates a potential gastrointestinal bleeding emergency. Assessing the client's vital signs is essential to monitor their hemodynamic status. Starting an IV with an 18-gauge needle is crucial to establish access for potential fluid resuscitation or blood transfusion. Beginning iced saline lavage is not appropriate in this situation and could potentially delay necessary interventions. Therefore, the correct interventions for the nurse to implement are to assess the client's vital signs and start an IV, making option D the most appropriate choice. Options A and B are correct because they are essential initial steps in managing gastrointestinal bleeding. Option C is incorrect as iced saline lavage is not indicated and may not address the urgent needs of the client in this critical situation.

Correct Answer: B

Rationale: The correct answer is B: Gastritis may cause bleeding. In patients with hiatal hernia, gastritis can occur due to the reflux of stomach acid into the esophagus. This gastritis can lead to gastrointestinal bleeding, resulting in anemia. Choice A is incorrect because iron absorption is not necessarily reduced in hiatal hernia. Choice C is incorrect as iron stores turnover rate is not directly related to the development of anemia in this context. Choice D is incorrect as an aversion to iron-rich foods is not a common reason for anemia in patients with hiatal hernia.

Correct Answer: D

Rationale: Assisting the client to sit in a chair is an essential nursing intervention postoperatively as it helps promote circulation, prevent complications like blood clots, and aids in the recovery process. Changing the infusion rate of intravenous fluid (Choice A) requires a physician's order and is not an independent nursing intervention. Encouraging the client to discuss feelings (Choice B) is important for emotional support but not as crucial as physical care immediately postoperatively. Administering opioid narcotic medications (Choice C) for pain management should be based on a prescribed schedule and assessment rather than being an independent nursing action.

Correct Answer: A

Rationale: The correct answer is to instruct the client to walk 15 to 20 minutes three times a day. Walking is beneficial as it helps improve circulation and reduces the risk of complications following sclerotherapy. Choice B is incorrect because keeping the legs in the dependent position when sitting can lead to increased venous pressure, worsening varicose veins. Choice C is incorrect as compression bandages should typically be worn continuously, especially during the initial healing phase. Choice D is incorrect as Berger-Allen exercises are not commonly associated with post-sclerotherapy care.
