Based on the diagnosis of Dehydration, select which IV solution will be ordered to treat waiting this patient.
5% dextrose in Lactated ringers
0.45% sodium chloride
0.9 Sodium chloride
3% Normal Saline
The Correct Answer is C
0.9% Sodium chloride is a balanced isotonic solution that closely resembles the electrolyte composition of the extracellular fluid. It is commonly used to treat dehydration because it helps restore fluid volume and electrolyte balance in the body.
5% dextrose in Lactated Ringers: This solution is typically used for fluid and electrolyte replacement in patients who have significant fluid losses or imbalances, but it may not be the best choice for dehydration alone.
0.45% sodium chloride: This solution, also known as half-normal saline, has a lower concentration of sodium chloride and is often used for patients who require hypotonic fluids. It may not provide enough electrolyte replacement for a dehydrated patient. 3% Normal Saline: This solution has a higher concentration of sodium chloride and is typically used for specific indications, such as severe hyponatremia or in critical care settings. It is not the first-line choice for treating dehydration.

Correct Answer is D
Explanation
During triage in a disaster situation, a color tagging system is often used to prioritize and categorize the injured based on the severity of their injuries and the urgency of medical attention required. The colors commonly used in triage are:
● Green tag: Minor injuries that are non-urgent and can typically wait for medical treatment.
● Yellow tag: Injuries that are significant but not immediately life-threatening, requiring medical attention within a few hours.
● Red tag: Critical injuries that are life-threatening but still salvageable with prompt medical intervention.
● Black tag: Injuries that are severe and unsurvivable or incompatible with life. This tag is assigned to individuals who are deceased or have injuries that are beyond the resources available for treatment.
In the given scenario, the absence of breathing, absent radial pulse, prolonged capillary refill, and unresponsiveness indicate a critical condition with no signs of life. Therefore, a black tag would be assigned to this individual.
Correct Answer is C
Explanation
The pH value of 7.5 indicates alkalosis, as it is above the normal range of 7.35-7.45. The elevated bicarbonate (HCO3-) level of 34 mmol/L suggests metabolic alkalosis, as it is higher than the normal range of 22-28 mmol/L. The PaCO2 level of 40 mm Hg falls within the normal range of 35-45 mm Hg.
In this case, the primary disturbance is metabolic alkalosis, which is likely caused by vomiting leading to excessive loss of gastric acid (hydrogen ions) and chloride ions from the stomach. This loss of acid and chloride results in an imbalance of electrolytes and an increase in bicarbonate levels, leading to metabolic alkalosis.
The arterial blood gas results do not indicate any compensation. Compensation occurs when the body attempts to restore the pH balance by adjusting the respiratory or metabolic systems. In this case, there is no compensation observed because the PaCO2 level is within the normal range and not significantly altered.
