A nurse is assessing a client who has tension pneumothorax. Which of the following findings should the nurse expect following tracheal deviation?
Respiratory alkalosis
Increased venous return
Decreased cardiac output
Dilated ventricles
The Correct Answer is C
Choice A Reason:
Respiratory alkalosis is incorrect. Tension pneumothorax typically leads to respiratory distress and hypoxemia rather than respiratory alkalosis. The respiratory alkalosis may occur initially due to hyperventilation in response to hypoxemia but would not be directly related to tracheal deviation.
Choice B Reason:
Increased venous return is incorrect. Tension pneumothorax actually leads to decreased venous return due to compression of the great vessels in the thorax, particularly the superior vena cava and the inferior vena cava. This compression results from the increased pressure within the thorax, which impedes blood flow back to the heart.
Choice C Reason:
Decreased cardiac output is incorrect. Tension pneumothorax can indeed lead to decreased cardiac output due to compression of the heart and the great vessels by the accumulating air in the pleural space. This compression decreases venous return and impairs cardiac function.
Choice D Reason:
Dilated ventricles is incorrect. As mentioned earlier, tension pneumothorax can lead to compression of the heart, including the ventricles. This compression can cause dilatation of the ventricles, particularly the right ventricle, due to increased afterload and decreased venous return.

Correct Answer is ["A","B","D"]
Explanation
Choice A Reason:
"Have you had any nausea and vomiting with your headache?": This question is appropriate. Nausea and vomiting are common symptoms associated with migraines. Asking about these symptoms can help confirm the diagnosis of a migraine headache.
Choice B Reason:
"Are you bothered by the lights in here?" This question is appropriate. Sensitivity to light, known as photophobia, is a classic symptom of migraines. Inquiring about light sensitivity can provide additional evidence for the diagnosis.
Choice C Reason:
"Have you noticed any confused or cloudy thinking?". This question is inappropriate. Confusion or cognitive symptoms are not typical of migraines. However, some individuals may experience difficulty concentrating or cognitive symptoms during a migraine aura. This question may help assess for aura symptoms.
Choice D Reason
Have you experienced or are you experiencing any strange smells?" This question is appropriate. Some individuals may experience olfactory hallucinations or sensitivity to odors during a migraine aura. Asking about strange smells can help identify possible aura symptoms.
Choice E Reason:
"Did you feel weak before the headache started or do you feel weak now?" This question is inappropriate. While weakness is not a typical symptom of migraines, some individuals may experience fatigue or muscle weakness during a migraine attack. This question may help assess the overall impact of the headache on the client.
Correct Answer is ["B","C","E"]
Explanation
Choice A Reason:
Photosensitivity is incorrect. Photosensitivity, or sensitivity to light, is not a common symptom of multiple sclerosis. While individuals with MS may experience visual disturbances, such as blurred vision or optic neuritis, sensitivity to light is not typically reported as a primary symptom.
Choice B Reason:
Memory issues is correct. Memory issues, including problems with short-term memory, concentration, and cognitive processing speed, are common neurological symptoms in individuals with multiple sclerosis. Cognitive impairment can affect various aspects of memory and cognitive function.
Choice C Reason:
Lhermitte's sign is correct. Lhermitte's sign is a classic neurological sign characterized by an electric shock-like sensation that radiates down the spine or into the limbs upon flexing the neck. It is a common symptom in multiple sclerosis, often associated with cervical spinal cord lesions.
Choice D Reason:
Seizures is incorrect. Seizures are not a typical symptom of multiple sclerosis. While individuals with MS may experience various neurological symptoms, seizures are not a common manifestation of the disease.
Choice E Reason:
Central vision loss is correct. Visual disturbances, including central vision loss, blurred vision, double vision, or optic neuritis, are common symptoms of multiple sclerosis. Optic neuritis, inflammation of the optic nerve, is a frequent manifestation of MS that can lead to temporary or permanent central vision loss.
