A nurse is teaching a class about the use of pain medications for clients who have an opioid addiction. Which of the following medications are a nonopioid analgesic? (Select All that Apply)

A) Anxiety: Anxiety is a subjective finding because it represents the client's perception of their emotional state. It is a feeling of unease, worry, or fear, which the client reports experiencing. Subjective findings are based on the client's self-report or feelings.

B) Alert: Being alert is an objective finding because it refers to the client's level of consciousness and responsiveness to stimuli. In this scenario, the nurse assesses that the client is alert based on their ability to respond appropriately to questions and stimuli in the environment.

C) Pacing: Pacing is an objective finding because it describes observable behavior. In this case, the nurse observes the client pacing in the room, which is a physical activity that can be seen or measured.

D) Restless: Restlessness is an objective finding because it describes observable behavior. The nurse assesses that the client appears restless based on their observed behavior of pacing in the room. Restlessness is a physical manifestation of the client's anxiety and is observable by others.

A) Cheyne-Stokes respirations:
Cheyne-Stokes respirations are characterized by a cycle of gradually increasing and then decreasing respirations followed by a period of apnea. This pattern repeats in a regular cycle. It is commonly observed in clients with conditions affecting the central nervous system, such as traumatic brain injury, stroke, or brain tumors. Cheyne-Stokes respirations can also occur during the dying process. The alternating periods of hyperventilation and apnea result from fluctuations in oxygen and carbon dioxide levels in the blood.

B) Kussmaul respirations:
Kussmaul respirations are deep, rapid, and labored breathing patterns often observed in clients with metabolic acidosis, particularly diabetic ketoacidosis. Unlike Cheyne-Stokes respirations, Kussmaul respirations do not involve periods of apnea.

C) Apneustic respirations:
Apneustic respirations are characterized by prolonged inspiratory gasps followed by insufficient expiration. This irregular breathing pattern typically indicates damage to the pons, a part of the brainstem involved in regulating breathing. Apneustic respirations are different from the pattern described in the scenario.

D) Stridor:
Stridor is a high-pitched, noisy respiratory sound heard on inspiration that indicates upper airway obstruction, such as from swelling, foreign body aspiration, or tumors. It is not associated with the alternating pattern of hyperventilation and apnea described in Cheyne-Stokes respirations.
