A nurse is doing hourly rounding and finds a client unresponsive. The nurse is unable to obtain a pulse and the client is not breathing. What intervention would be the priority for this client?

Choice A Reason:

Atelectasis is a common postoperative complication, especially in patients who have undergone abdominal or thoracic surgery. It occurs when the alveoli in the lungs collapse, leading to reduced or absent breath sounds in the affected areas. This condition can result from shallow breathing, pain, or immobility after surgery. The absence of breath sounds in the bases of the lungs is a key indicator of atelectasis. Preventive measures include encouraging deep breathing exercises, using incentive spirometry, and early mobilization of the patient.

Choice B Reason:

Pulmonary embolism (PE) is a serious condition where a blood clot travels to the lungs, causing a blockage in one of the pulmonary arteries. While PE can present with symptoms such as sudden shortness of breath, chest pain, and rapid heart rate, it is less likely to cause absent breath sounds in the lung bases. Instead, PE may lead to decreased oxygen levels and respiratory distress. Diagnosis typically involves imaging studies such as a CT pulmonary angiography.

Choice C Reason:

Arterial thrombus refers to a blood clot that forms in an artery, which can lead to tissue ischemia and infarction. This condition is more commonly associated with cardiovascular events such as myocardial infarction or stroke. It does not typically present with absent breath sounds in the lungs. Instead, symptoms may include pain, pallor, and loss of function in the affected area. Diagnosis and treatment focus on restoring blood flow to the affected tissues.

Choice D Reason:

Pneumonia is an infection of the lungs that can cause symptoms such as cough, fever, and difficulty breathing. While pneumonia can lead to abnormal breath sounds, such as crackles or wheezes, it is less likely to cause completely absent breath sounds in the lung bases. Pneumonia is usually diagnosed through clinical examination, chest X-rays, and sputum cultures. Treatment involves antibiotics and supportive care to manage symptoms.

Choice A Reason:

Restlessness is often one of the earliest signs of hypoxia. When the body experiences low oxygen levels, the brain is one of the first organs to be affected. This can lead to symptoms such as anxiety, agitation, and restlessness as the brain struggles to function properly without adequate oxygen. These symptoms occur because the body is trying to compensate for the lack of oxygen by increasing respiratory and heart rates, which can make a person feel uneasy or restless.

Choice B Reason:

Cyanosis refers to a bluish discoloration of the skin and mucous membranes due to low oxygen levels in the blood. While cyanosis is a significant indicator of hypoxia, it is typically a later sign. By the time cyanosis is visible, hypoxia has usually been present for some time, and oxygen levels have been critically low. Therefore, it is not the earliest clinical manifestation of hypoxia.

Choice C Reason:

Apnea is the absence of breathing. This is a severe and late sign of hypoxia. When a person stops breathing, it indicates that the body has been deprived of oxygen for an extended period, leading to critical conditions. Apnea is a medical emergency and requires immediate intervention, but it is not an early sign of hypoxia.

Choice D Reason:

Bradycardia is a slower than normal heart rate. Like apnea, bradycardia is a late sign of hypoxia. Initially, the body responds to low oxygen levels by increasing the heart rate (tachycardia) to pump more oxygenated blood to tissues. Bradycardia occurs when the body can no longer compensate, and the heart rate slows down, indicating severe hypoxia and impending failure of the cardiovascular system.
