Electrolytes Question #69
The nurse is caring for a client with hyponatremia secondary to syndrome of inappropriate antidiuretic hormone (SIADH). Which intravenous solution will the nurse expect to be prescribed?
- Lactated Ringers
The correct answer is A. When hyponatremia is severe. hypertonic solutions may be used but should be infused with caution due to the potential for development of heart failure. In SIADH. isotonic and hypotonic solutions are not indicated. This is because urine output is minimal and water is retained. Isotonic and hypotonic solutions would exacerbate fluid overload.
NCLEX TIP: Using critical thinking is recommended when reading priority questions. Recognizing key words in the answer choices will allow you to know how to choose the correct answer for the question. Go through each answer choice and decide is it: Maslow’s hierarchy, safety-related, or following the nursing process (ADPIE). Never complete a nursing action that is outside the scope of practice.
