Which of the following is the most common risk factor for emphysema?

Smoking tobacco

Between 20 to 30 years of age

Asthma

Pollution

Answer and Explanation

The Correct Answer is A

Choice A Reason:

Smoking tobacco is the primary and most significant risk factor for emphysema. Tobacco smoke contains harmful chemicals and toxins that directly damage the lungs. Chronic exposure to cigarette smoke leads to inflammation and destruction of lung tissue, particularly the alveoli, contributing to the development of emphysema.

Choice B Reason:

Between 20 to 30 years of age. While smoking at any age is harmful to lung health, the risk of developing emphysema increases with prolonged exposure to tobacco smoke over many years. Emphysema is typically a disease of middle to older age, with symptoms often appearing after years of smoking.

Choice C Reason:

Asthma is a chronic inflammatory condition of the airways characterized by reversible airflow obstruction and airway hyperresponsiveness. While asthma and emphysema are both respiratory diseases, they have distinct pathophysiological mechanisms and risk factors. Asthma is not a direct cause of emphysema, although some individuals with poorly controlled asthma may develop chronic obstructive pulmonary disease (COPD), which includes emphysema as one of its components.

Choice D Reason:

Pollution is not correct. Environmental pollution, including air pollution from industrial emissions, vehicle exhaust, and particulate matter, can contribute to respiratory problems and exacerbate pre-existing lung conditions. While exposure to pollution can worsen respiratory symptoms and lung function, it is not the primary cause of emphysema. However, long-term exposure to certain pollutants may increase the risk of developing respiratory diseases, including COPD, which encompasses emphysema.

Correct Answer is A

Explanation

Choice A Reason:

The client has no sensation or movement below the level of the injury is correct. This is a characteristic finding of a complete spinal cord injury, where there is total loss of sensory and motor function below the level of the injury. This pattern is often seen in injuries involving the cervical spinal cord, such as at the level of C7.

Choice B Reason:

The client has some movement but no sensation below the level of the injury is incorrect. This finding would be more indicative of an incomplete spinal cord injury, where there is partial preservation of sensory or motor function below the level of the injury. However, with a transection of the spinal cord at C7, it is less likely for the client to have retained movement below the level of injury.

Choice C Reason:

The client has some movement and also some sensation below the level of the injury is incorrect. This finding is not typically associated with a spinal cord injury at the level of C7. With a transection of the spinal cord at this level, there is typically complete loss of sensory and motor function below the level of the injury.

Choice D Reason:

The client has some sensation but no movement below the level of the injury is incorrect. This finding is more consistent with an incomplete spinal cord injury, where there may be partial preservation of sensory function but no motor function below the level of the injury. However, with a transection of the spinal cord at C7, it is less likely for the client to have retained sensation below the level of injury.

A. Temperature 36.3° C (97.4° F) B. Respirations 12/min C. Blood pressure 184/88 mm Hg D. Heart rate 54/min E. Calcium level 7.0 mg/dL

Correct Answer is ["A","D"]

Explanation

Choice A Reason:

Temperature 36.3°C (97.4°F) is correct. Hypothermia is a characteristic finding in neurogenic shock due to the loss of sympathetic control over temperature regulation and peripheral vasodilation. This can lead to heat loss from the skin surface and a decrease in core body temperature.

Choice B Reason:

Respirations 12/min is incorrect. Respiratory rate is usually not significantly affected in neurogenic shock. However, individuals with high cervical or upper thoracic spinal cord injuries may experience respiratory compromise due to paralysis of respiratory muscles, but this is not a typical feature of neurogenic shock.

Choice C Reason:

Incorrect: Neurogenic shock typically results inhypotension(low blood pressure) due to vasodilation. The given blood pressure reading is elevated, which is not consistent with neurogenic shock.

Choice D Reason:

Heart rate 54/min is correct. Bradycardia is a common finding in neurogenic shock due to unopposed parasympathetic activity resulting from the loss of sympathetic tone. The heart rate may be slow and may decrease further over time.

Choice E Reason:

Calcium level 7.0 mg/dL is incorrect, Calcium levels are not directly related to neurogenic shock. Neurogenic shock primarily involves the loss of sympathetic tone and the resulting hemodynamic changes, rather than alterations in calcium metabolism.
