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 milliliters per hour (mL/hr) for the IV infusion, you divide the total volume (in milliliters) by the total time (in hours).
In this case, the total volume is 1 liter, which is equal to 1000 milliliters, and the total time is 6 hours.
So, you divide 1000 mL by 6 hours:
1000 mL / 6 hours = 166.67 mL/hr
Rounding off, the nurse will program the IV infusion device to infuse at approximately 167 mL/hr.
Correct Answer is C
Explanation
Excessive exposure to UV light, such as sunlight or tanning beds, is a known trigger for SLE exacerbations. It is important for individuals with SLE to protect their skin from the sun by wearing protective clothing, using sunscreen, and avoiding direct sunlight during peak hours. Having a family history of SLE increases the risk of developing the disease. While it is not a trigger in itself, it is an important piece of information for the client to be aware of, as it may indicate a genetic predisposition to the condition.
Acetaminophen is a commonly used over-the-counter pain reliever. While it can help manage pain associated with SLE, it is not typically considered a trigger for exacerbations. Menopause, which marks the end of a woman's reproductive years, does not directly trigger SLE exacerbations. However, hormonal changes during menopause can potentially affect disease activity in some individuals. It is important for the client to discuss any changes or concerns with their healthcare provider to manage their symptoms effectively.
