A nurse is caring for a client who is receiving oxygen therapy via a nasal cannula. How should the nurse explain to the client how this method of oxygen delivery performs?

Choice A Reason:

Loperamide should not be used if diarrhea is infectious is correct. Loperamide is an antidiarrheal medication that works by slowing down gut movement. However, if the diarrhea is caused by an infection, such as from spoiled food, it is important to allow the body to expel the infectious agents. Using loperamide in such cases can prolong the infection and potentially worsen the condition.

Choice B Reason:

You can take loperamide until the diarrhea stops is incorrect. While loperamide can be effective for non-infectious diarrhea, it is not recommended for infectious diarrhea. Stopping the diarrhea prematurely can trap the infectious agents in the intestines, leading to more severe symptoms.

Choice C Reason:

Loperamide has no side effects is incorrect. Loperamide can have side effects, including constipation, dizziness, and abdominal pain. It is important to use this medication under the guidance of a healthcare provider, especially in cases of infectious diarrhea.

Choice D Reason:

Loperamide should not stop this type of diarrhea is incorrect. While it is true that loperamide should not be used for infectious diarrhea, the statement is misleading. Loperamide can stop diarrhea, but it is not appropriate for all types of diarrhea, particularly those caused by infections.

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.
