Final answer:
When a client becomes dehydrated due to a nasogastric tube connected to continuous suction, the expected clinical finding is inelastic skin turgor. Other symptoms can include restlessness and decreased blood pressure. Sodium levels and osmosis play key roles in regulating blood pressure, with dehydration potentially leading to serious health consequences. so, option a is the correct answer.
Step-by-step explanation:
If a client with an intestinal obstruction becomes dehydrated due to the nasogastric tube being connected to low, continuous suction, the clinical finding that a nurse would expect is inelastic skin turgor. Dehydration can result in a range of symptoms, including restlessness, decreased blood pressure (hypotension), increased pulse rate, dryness and wrinkling of the skin, and exhaustion. Dehydration due to factors like prolonged vomiting or diarrhoea leads to excessive loss of digestive fluids and can significantly affect electrolyte balance, particularly sodium (Na+) levels, which in turn affects the volume of body water.
An important concept in dehydration is the role of sodium and osmosis in blood pressure regulation. Water tends to follow the concentration gradient of sodium, and when there is a loss of sodium through the gut or kidneys, corresponding water loss can lead to low blood pressure and decreased cellular function. In severe cases, dehydration can contribute to impaired renal function and vascular volume control, which can cause serious health issues like stroke or heart attack due to fluctuations in blood pressure.
