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 B
Explanation
Choice A Reason:
Listening to the client’s speech is not a method used to assess cranial nerve V. This method is more relevant for assessing cranial nerves IX (Glossopharyngeal) and X (Vagus), which are involved in speech and swallowing.
Choice B Reason:
Clenching the teeth is a method used to assess the motor function of cranial nerve V (the trigeminal nerve). The trigeminal nerve is responsible for the movement of the muscles involved in chewing. When a client clenches their teeth, the nurse can palpate the masseter and temporal muscles to check for strength and symmetry. This helps determine if there are any abnormalities in the motor function of the trigeminal nerve.
Choice C Reason:
Asking the client to read a Snellen chart is a method used to assess cranial nerve II (Optic), which is responsible for vision. This method does not assess cranial nerve V.
Choice D Reason:
Asking the client to raise his eyebrows is a method used to assess cranial nerve VII (Facial), which controls facial expressions. This method is not used to assess cranial nerve V.
Correct Answer is A
Explanation
Choice A reason: The glossopharyngeal nerve (CN IX) is primarily responsible for the gag reflex. It provides sensory input from the pharynx and posterior third of the tongue, which triggers the gag reflex when stimulated. This nerve plays a crucial role in swallowing and the reflexive action to prevent choking.
Choice B reason: The trigeminal nerve (CN V) is responsible for facial sensation and motor functions such as biting and chewing. It does not play a direct role in the gag reflex. While it is important for other sensory and motor functions, it is not involved in the reflex being assessed here.
Choice C reason: The vagus nerve (CN X) also contributes to the gag reflex by providing motor innervation to the muscles of the pharynx and larynx. However, the primary sensory input for the gag reflex comes from the glossopharyngeal nerve (CN IX). The vagus nerve works in conjunction with CN IX to complete the reflex action.
Choice D reason: The hypoglossal nerve (CN XII) controls the movements of the tongue. It is essential for speech and swallowing but does not have a role in the gag reflex. The hypoglossal nerve’s primary function is motor control of the tongue muscles.
