Colleen, a 19 year old Freshman, was drinking alcohol at a frat party. She stupors, falls and hits her head on the ground. Her friend Julie dials "911" because Colleen is now unconscious, depressed ventilation (shallow and slow respirations), rapid heart rate, and is profusely bleeding from both ears. Which primary acid-base imbalance is Colleen at risk for if medical attention is not provided?
Metabolic Acidosis
Respiratory Acidosis
Respiratory Alkalosis
Metabolic Alkalosis
The Correct Answer is B
Respiratory acidosis is a primary acid-base imbalance that occurs when there is an excess of carbon dioxide (CO2) in the body due to impaired ventilation or inadequate removal of CO2 from the lungs. In this case, Colleen's depressed ventilation, indicated by shallow and slow respirations, can lead to inadequate elimination of CO2 from her body. The excessive CO2 levels can result in an accumulation of carbonic acid (H2CO3) in the blood, leading to an increase in acidity and a decrease in pH.
The profuse bleeding from both ears indicates a potential head injury, which can lead to decreased neurological function and impaired control over the respiratory center in the brain. This can further contribute to depressed ventilation and the development of respiratory acidosis. Metabolic acidosis, characterized by a decrease in bicarbonate (HCO3-) levels or an increase in non-carbonic acids in the blood, is not the primary acid-base imbalance in this case since the scenario does not provide information indicating a primary metabolic disorder. Respiratory alkalosis, characterized by decreased levels of CO2 in the blood, leading to increased pH and alkalinity, is not the primary acid-base imbalance in this case. The depressed ventilation and associated increase in CO2 levels indicate the opposite, respiratory acidosis. Metabolic alkalosis, characterized by an increase in bicarbonate levels or a decrease in non-carbonic acids, is not the primary acid-base imbalance in this case as the scenario does not provide information indicating a primary metabolic disorder.

Correct Answer is D
Explanation
To calculate the patient's body mass index (BMI), we need to divide the weight (in kilograms) by the square of the height (in meters). Let's convert the height and weight measurements to the appropriate units and perform the calculation:
Height: 5 feet, 6 inches = 5 + (6/12) = 5.5 feet = 1.6764 meters (rounded to four decimal places) Weight: 250 lb. = 113.3 kg
BMI = Weight (kg) / (Height (m))^2
BMI = 113.3 kg / (1.6764 m)^2
BMI ≈ 40.0
Correct Answer is D
Explanation
The development of nausea and increased upper abdominal bowel sounds after 24 hours of NG decompression in a patient with gastric outlet obstruction raises concerns for possible complications or changes in the patient's condition. Assessing the patient's vital signs, including blood pressure, heart rate, respiratory rate, and oxygen saturation, can provide important information about their circulatory status and overall stability.
While checking the patency of the NG tube is important, it is not the best immediate action in this situation. The nurse should first assess the patient's vital signs to ensure their stability before proceeding with further interventions.
Placing the patient in a recumbent position (lying down) or encouraging deep breathing and conscious relaxation may not address the underlying issue and could potentially exacerbate the symptoms. It is essential to assess the patient's vital signs and circulatory status to determine the appropriate course of action.
