What should the nurse do when a client is experiencing hyperglycemia?

Correct Answer: A

Rationale: The correct answer is A, administer insulin, because hyperglycemia indicates high blood sugar levels which can be effectively lowered by administering insulin. Insulin helps to move glucose from the blood into cells for energy production. Administering fluids (B) can be helpful for dehydration, but it does not directly address the high blood sugar levels. Encouraging activity (C) may help lower blood sugar levels over time, but in the immediate situation, administering insulin is more effective. Encouraging deep breathing (D) does not directly address hyperglycemia and would not be the appropriate first step in managing this condition.

Correct Answer: A

Rationale: The correct answer is A: Administer bronchodilators. During an acute asthma attack, the priority is to open the airways quickly to improve breathing. Bronchodilators work rapidly to dilate the constricted airways, providing immediate relief. Corticosteroids are used for long-term management and take time to be effective. Administering morphine is not recommended as it can depress the respiratory system. Performing an ECG is not necessary in the acute management of an asthma attack.

Correct Answer: B

Rationale: The correct answer is B: Administer antibiotics. When caring for a client with severe burns, the first priority is to prevent infection, which can be life-threatening. Administering antibiotics helps reduce the risk of infection. Cleansing and dressing the wounds can come after ensuring infection control. Performing a tracheostomy is not typically the first priority unless there are airway concerns. Administering analgesics is important, but it is not the first priority in this case.

Correct Answer: A

Rationale: The correct answer is A: Administer bronchodilators. During an acute asthma attack, bronchodilators are the first-line treatment to quickly relieve bronchospasm and improve airflow. They work by relaxing the muscles around the airways, allowing the client to breathe easier. Administering corticosteroids (choices B and C) is important but typically done after bronchodilators to reduce airway inflammation. Encouraging fluid intake (choice D) is not the priority in an acute asthma attack, as the focus should be on addressing the breathing difficulty promptly.

Correct Answer: D

Rationale: The correct answer is D: Administer corticosteroids. In a client with chest pain and a history of myocardial infarction, the first priority is to address potential inflammation in the myocardium. Corticosteroids help reduce inflammation and stabilize the myocardium, which is crucial in preventing further damage post-myocardial infarction. Administering nitroglycerin (A) is important for vasodilation, but it is typically used after corticosteroids. Morphine (B) and analgesics (C) may provide pain relief but do not address the underlying inflammation. Administering corticosteroids is the most appropriate first step to manage myocardial inflammation and protect the heart tissue.
