Medical Surgical Assignment Exam HESI

Correct Answer: B

Rationale: High levels of carbon dioxide in the blood lead to respiratory acidosis due to inadequate ventilation. The correct answer is B. In respiratory acidosis, the accumulation of carbon dioxide in the blood occurs due to inadequate exhalation, leading to acidosis. Choice A is incorrect as low oxygen levels are related to hypoxemia, not respiratory acidosis. Choice C is incorrect as increased bicarbonate levels would lead to alkalosis, not acidosis. Choice D is incorrect as an increased respiratory rate causing hyperventilation would actually help decrease carbon dioxide levels, not lead to respiratory acidosis.

Correct Answer: D

Rationale: In a client with AIDS and impaired gas exchange from a respiratory infection, pain when swallowing can indicate esophageal involvement, such as esophagitis or an esophageal infection like candidiasis. These conditions can significantly impact the client's ability to take in nutrition and medications, leading to complications like dehydration and malnutrition. Therefore, immediate intervention is required to address the underlying cause and prevent further complications. Elevated temperature (choice A) may indicate infection but does not directly address the impaired gas exchange. Generalized weakness (choice B) and diminished lung sounds (choice C) are concerning but do not directly relate to the immediate need for intervention in the context of esophageal involvement in a client with impaired gas exchange.

Correct Answer: B

Rationale: The correct instruction for a client with chronic venous insufficiency is to elevate their legs above heart level when resting. This position helps reduce venous pressure and edema, improving circulation. Avoiding compression stockings (choice A) is incorrect as they are beneficial in managing chronic venous insufficiency. Applying heat packs (choice C) is not recommended as heat can worsen edema. Limiting walking (choice D) is not advisable as regular, gentle exercise like walking can actually help improve circulation in patients with chronic venous insufficiency.

Correct Answer: C

Rationale: Placing the client in an upright position during meals is the correct intervention to prevent aspiration in a client with Parkinson's disease. This position helps facilitate swallowing and reduces the risk of aspiration. Choice A is incorrect because encouraging the client to eat quickly can increase the risk of choking and aspiration. Choice B is not the best option as straws may not prevent aspiration effectively. Choice D is incorrect as thin liquids can actually increase the risk of aspiration in individuals with swallowing difficulties.

Correct Answer: D

Rationale: The correct answer is D, as all the listed factors - abdominal obesity, high blood pressure, and increased triglyceride levels - are components of metabolic syndrome. Addressing these findings is crucial to help reduce the client's risk for developing diabetes mellitus and vascular disease. Abdominal obesity is a key feature of metabolic syndrome, high blood pressure (150/96 mmHg) is a risk factor, and increased triglyceride levels are also indicative of the syndrome. Educating the client on lifestyle modifications, such as healthy eating habits, regular physical activity, and monitoring these parameters, is essential in managing metabolic syndrome and preventing associated complications. Choices A, B, and C are all correct, making choice D the correct answer.
