An adolescent arrives at the emergency department (ED) with a fever and persistent lower right quadrant abdominal pain.
The patient is anxious, fearful, and hyperventilating.
What acid-base imbalance does the nurse anticipate the patient will develop?
Respiratory alkalosis.
Respiratory acidosis.
Metabolic alkalosis.
Metabolic acidosis.
The Correct Answer is A
Choice A rationale
Hyperventilation leads to a decrease in the amount of carbon dioxide (CO2) in the blood. This causes the pH of the blood to increase, resulting in respiratory alkalosis.
Choice B rationale
Respiratory acidosis is caused by a buildup of CO2 in the blood, typically due to hypoventilation (under-breathing). This is not consistent with the patient’s symptoms of hyperventilation.
Choice C rationale
Metabolic alkalosis is typically caused by a significant loss of acid from the body, such as from prolonged vomiting. This is not consistent with the patient’s symptoms.
Choice D rationale
Metabolic acidosis is typically caused by an increase in acid production within the body or a loss of bicarbonate from the body, such as in diabetic ketoacidosis or kidney disease. This is not consistent with the patient’s symptoms.

Correct Answer is B
Explanation
Choice A rationale
While regular monitoring of blood sugar levels is important in managing diabetes, checking every four to six hours every day may not be necessary for all patients. The frequency of blood glucose monitoring should be individualized based on the type and severity of the diabetes, the patient’s blood glucose control, and the patient’s specific needs.
Choice B rationale
Keeping diabetic medication on schedule as prescribed is crucial in managing blood glucose levels and preventing complications related to diabetes. This indicates that the patient has understood the importance of medication adherence in diabetes management.
Choice C rationale
While it’s recommended to limit alcohol consumption, restricting alcoholic beverages to no more than 1-2 per week is not a standard guideline for all patients with diabetes. The effects of alcohol on blood glucose levels can vary depending on several factors, including the amount of alcohol consumed, the presence of food, and the individual’s overall diabetes management.
Choice D rationale
Limiting daily fat intake to 15% of total calories is not a standard recommendation for patients with diabetes. The American Diabetes Association recommends individualized medical nutrition therapy to manage diabetes, which may include monitoring carbohydrate intake and considering the quality of fats and proteins in the diet.
Correct Answer is B
Explanation
Choice A rationale
Verifying that the nurse has gathered the necessary supplies is important, but it is not the most critical action in this scenario. The new nurse has already gathered the necessary supplies for the procedure.
Choice B rationale
This is the correct answer. A transparent dressing is preferred over a gauze dressing for securing an IV catheter. It allows for easy inspection of the insertion site for signs of infection.
Choice C rationale
Ensuring that the gauze dressing is taped securely in place is not the most critical action in this scenario. As mentioned, a transparent dressing is generally preferred for securing an IV catheter.
Choice D rationale
While inspecting the secured IV site after the insertion procedure is important, advising the nurse to use a transparent dressing over the site is a more immediate need. This will allow for continuous visual inspection of the site.
