HESI RN Exit Exam 2024 Quizlet Capstone

Correct Answer: A

Rationale: The most important instruction for a patient following cataract extraction is to avoid straining, bending, or lifting heavy objects. These activities can increase intraocular pressure and potentially lead to complications such as bleeding or dislocation of the intraocular lens. Choices B, C, and D are not as critical in the immediate post-operative period. Limiting sunlight exposure and using direct lighting when reading are important but not as crucial as avoiding activities that can increase intraocular pressure. Irrigating the conjunctiva with saline before applying ointment is not a standard post-cataract surgery instruction.

Correct Answer: D

Rationale: A serum calcium level of 7.5 mg/dL is indicative of hypocalcemia, a common complication in clients with chronic kidney disease due to impaired calcium absorption and metabolism. Hypercalcemia (Choice A) is the opposite of the condition presented in the question and is characterized by elevated serum calcium levels. Hyperkalemia (Choice B) is an increased potassium level, not related to the client's serum calcium level. Hyponatremia (Choice C) is a decreased sodium level and is also not related to the client's serum calcium level.

Correct Answer: B

Rationale: The correct answer is to position the child sitting up and leaning forward. This position helps prevent blood from flowing down the throat, reducing the risk of choking or vomiting. Choice A is incorrect because lying flat can cause blood to flow down the throat. Choice C is wrong as tilting the head back may lead to blood entering the throat. Choice D is also incorrect as applying ice is not recommended for nosebleeds and lying on the side may not prevent blood from flowing down the throat.

Correct Answer: B

Rationale: The correct answer is B: Partial thromboplastin time (PTT). PTT is the lab value used to monitor the effectiveness of heparin therapy in clients with DVT. It measures the intrinsic pathway of coagulation and is prolonged by heparin therapy. Prothrombin time (PT) and International Normalized Ratio (INR) are primarily used to monitor warfarin therapy, not heparin. Checking hemoglobin and hematocrit levels is important but does not directly assess the effectiveness of heparin therapy in DVT.

Correct Answer: C

Rationale: The correct answer is C: Fresh or frozen vegetables without sauce. These foods are low in sodium, which is crucial for managing hypertension. Pickled olives (choice A) and canned soup (choice B) are high in sodium, which can exacerbate hypertension. While fruits without sauce (choice D) are generally healthy, emphasizing vegetables is more beneficial for hypertension due to their lower sodium content.
