The nurse is caring for a patient on contact precautions. Which action will be most appropriate to prevent the spread of disease?

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.

A) The client tolerates a second dose of medication with no greater than 1 peripheral edema:
This does not directly indicate a therapeutic response to epinephrine for angioedema. Angioedema primarily involves swelling of deeper layers of the skin, often around the eyes and lips, and sometimes the throat, which can cause breathing difficulties. Tolerating a second dose of medication with minimal peripheral edema does not specifically address the acute respiratory effects of angioedema.

B) Respirations are unlabored:
This is the correct answer. Angioedema can cause swelling in the airways, leading to difficulty breathing. Epinephrine is used to reduce this swelling and improve airway patency. Unlabored respirations indicate that the airway is not obstructed, which means the epinephrine has successfully alleviated the swelling causing the angioedema.

C) Client reports decreased groin pain of 3 on a 1 to 10 scale:
Decreased groin pain is not relevant to the treatment of angioedema with epinephrine. Pain relief in the groin area does not indicate a therapeutic response to epinephrine, which is primarily used to address airway and anaphylactic symptoms.

D) The client's blood pressure when arising from resting position is at premedication levels:
While epinephrine can affect blood pressure, the main concern with angioedema is airway obstruction rather than blood pressure control. Normalizing blood pressure does not specifically indicate that the epinephrine has successfully treated the angioedema and improved the client's respiratory status.
