A nurse is assessing a client who is 2 days postoperative and is auscultating their bilateral breath sounds. The nurse notes absent breath sounds in the bases. The nurse should suspect which postoperative complication is occurring in this client?
Atelectasis
Pulmonary embolism
Arterial thrombus
Pneumonia
The Correct Answer is A
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.

Correct Answer is C
Explanation
Choice A Reason:
The gastrocnemius muscle, located in the calf, is not a recommended site for intramuscular injections in newborns. This muscle is not typically used due to its small size and the difficulty in accessing it safely for an injection.
Choice B Reason:
The dorsogluteal muscle, located in the buttocks, is also not recommended for newborns. This site is avoided because of the risk of damaging the sciatic nerve and the relatively thick layer of subcutaneous fat, which can interfere with the absorption of the medication.
Choice C Reason:
The vastus lateralis muscle, located in the thigh, is the preferred site for intramuscular injections in newborns. This muscle is well-developed at birth and provides a large, easily accessible area for injections. It is also away from major blood vessels and nerves, making it a safe and effective site for administering medications like vitamin K.
Choice D Reason:
The ventrogluteal muscle, located on the side of the hip, is another site used for intramuscular injections, but it is not typically recommended for newborns. This site is more commonly used in older children and adults due to its deeper location and the need for precise anatomical knowledge to avoid complications.
Correct Answer is D
Explanation
Choice A Reason:
“Delivers a low concentration of oxygen” is incorrect because a nasal cannula can deliver varying concentrations of oxygen depending on the flow rate set by the healthcare provider. The concentration can range from low to moderate, typically between 24% to 44%.
Choice B Reason:
“Delivers a constant rate of oxygen” is partially correct but not entirely accurate. While the flow rate can be constant, the key aspect is the specific concentration of oxygen delivered, which is more relevant to the client’s understanding.
Choice C Reason:
“Delivers a high concentration of oxygen” is incorrect because nasal cannulas are generally used for low to moderate oxygen delivery. High concentrations of oxygen are typically delivered through other devices like non-rebreather masks or high-flow nasal cannulas.
Choice D Reason:
“Delivers a constant flow of a specific concentration of oxygen” is correct. This explanation accurately describes how a nasal cannula works. It provides a continuous flow of oxygen at a specific concentration, which is adjusted based on the client’s needs and the healthcare provider’s prescription.
