HESI RN Exit Exam 2024 Quizlet

Correct Answer: A

Rationale: Peaked T waves on the ECG are the most concerning finding in a client with hyperkalemia. Hyperkalemia can lead to serious cardiac complications, including arrhythmias and cardiac arrest. Peaked T waves are a classic ECG finding associated with hyperkalemia and indicate the need for immediate intervention. Bradycardia, muscle weakness, and decreased deep tendon reflexes can also be seen in hyperkalemia, but the presence of peaked T waves signifies a higher risk of cardiac events, making it the most concerning finding in this scenario.

Correct Answer: B

Rationale: A serum osmolarity of 320 mOsm/kg is concerning in a client with HHS because it indicates severe dehydration and hyperosmolarity, which requires immediate intervention. In HHS, the elevated serum osmolarity leads to neurological symptoms and can result in serious complications if not addressed promptly. While a high serum glucose level (choice A) is typical in HHS, the osmolarity is a more direct indicator of dehydration and severity. Serum sodium (choice C) and potassium levels (choice D) are important but do not pose an immediate threat to the client's condition compared to the severe hyperosmolarity indicated by a high serum osmolarity level.

Correct Answer: D

Rationale: The best initial response by the nurse when the client reports muscle weakness is to ask the client to describe the changes that have occurred. This approach allows the nurse to gain a better understanding of the client's experience, the extent of weakness, any associated symptoms, and potential triggers. By actively listening to the client's description, the nurse can gather valuable information that will aid in a comprehensive assessment and development of a tailored care plan. Choice A is incorrect because assuming muscle weakness is solely due to aging without further assessment can lead to overlooking potential underlying causes. Choice B is incorrect as observing for signs of muscle atrophy should come after gathering information directly from the client. Choice C is incorrect as reviewing diagnostic test results should not be the initial step when the client's current experience is being shared.

Correct Answer: C

Rationale: The correct answer is C: Orthopnea. If the client is orthopneic, the nurse needs to adapt the insertion position that does not place the client in a supine position. This means the head of the bed should be elevated as much as possible to facilitate catheter insertion without compromising the client's breathing. High urinary pH (choice A) is not directly relevant to the insertion position of a urinary catheter. Abdominal ascites (choice B) may impact the procedure due to abdominal distension but is not as crucial as orthopnea. Fever (choice D) does not specifically affect the client's position for urinary catheter insertion.

Correct Answer: D

Rationale: The correct answer is D: Evidence of hypoventilation. In a client with muscular dystrophy and progressive kyphoscoliosis, hypoventilation indicates respiratory muscle weakness and can lead to life-threatening respiratory distress. Immediate intervention is crucial to prevent complications. Choices A, B, and C are incorrect because while extremity muscle weakness, bilateral eyelid drooping, and inability to swallow pills are concerning symptoms in muscular dystrophy, evidence of hypoventilation poses a more immediate threat to the client's respiratory status.
