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
Suggesting that the child participate in a team sport to encourage socialization is not the best response. Duchenne muscular dystrophy (DMD) is a progressive disease that causes muscle weakness and loss of muscle mass. Participating in a team sport could be physically challenging for the child and could potentially lead to injury.
Choice B rationale
Encouraging the parents to allow the child to continue attending swimming lessons with supervision is the best response. Swimming is a low-impact exercise that can help maintain muscle strength and flexibility in children with DMD. It also provides an opportunity for socialization.
Choice C rationale
Explaining that the child is too young to understand the risks associated with swimming is not the best response. Children with DMD can participate in swimming with appropriate supervision and safety measures in place.
Choice D rationale
Providing a list of alternative activities that are less likely to cause the child to experience fatigue is not the best response. While it’s important to consider activities that are appropriate for the child’s physical abilities, it’s also important to consider the child’s interests. The child has expressed a desire to continue swimming, and with appropriate supervision, this activity can be beneficial.
Correct Answer is D
Explanation
Choice A rationale
Encouraging the client to participate in a team sport for one hour might be beneficial for the client’s physical health, but it might not be the most important intervention for a client with severe depression who spends most of the day sitting and watching television.
Choice B rationale
Assisting the client in developing a list of daily affirmations can be a helpful strategy for improving self-esteem and promoting positive thinking, but it might not be the most important intervention for a client with severe depression who spends most of the day sitting and watching television.
Choice C rationale
Scheduling the client for a group session that focuses on self-esteem can be beneficial for the client’s mental health, but it might not be the most important intervention for a client with severe depression who spends most of the day sitting and watching television.
Choice D rationale
Helping the client in identifying goals for the day can be a very effective intervention for a client with severe depression. Setting daily goals can provide the client with a sense of purpose and can help to motivate the client to engage in activities other than sitting and watching television.
