Restriction of which electrolyte is recommended in the management of high blood pressure?

Choice A reason: Infection in the blood is not empyema. It is sepsis, which is a life-threatening condition that occurs when the body's response to infection causes tissue damage, organ failure, or death.

Choice B reason: Infection in the pleural space is empyema. It is a collection of pus in the space between the lungs and the chest wall, usually caused by a bacterial infection that spreads from the lungs or the chest cavity.

Choice C reason: Exudative bronchitis is not empyema. It is a type of bronchitis that involves inflammation and excess mucus production in the bronchi, the airways that carry air to the lungs.

Choice D reason: Infection localized in the lung is not empyema. It is pneumonia, which is an inflammation of the lung tissue, usually caused by a viral or bacterial infection that affects the air sacs or the interstitial tissue.

Choice A reason: This is not a symptom that would indicate withholding a nonselective beta-adrenergic blocker. Hyperglycemia is a high level of glucose in the blood, which can be caused by diabetes or other conditions. Nonselective beta-adrenergic blockers do not affect blood glucose levels directly, but they may mask the signs of hypoglycemia (low blood glucose) in diabetic patients.

Choice B reason: This is not a symptom that would indicate withholding a nonselective beta-adrenergic blocker. Dizziness is a common side effect of many medications, especially those that lower blood pressure. Nonselective beta-adrenergic blockers can cause dizziness by reducing the heart rate and cardiac output, but this is usually mild and transient.

Choice C reason: This is not a symptom that would indicate withholding a nonselective beta-adrenergic blocker. Peripheral edema is swelling of the ankles, feet, or legs, which can be caused by heart failure, kidney disease, or venous insufficiency. Nonselective beta-adrenergic blockers do not cause peripheral edema, but they may worsen it in patients with heart failure.

Choice D reason: This is a symptom that would indicate withholding a nonselective beta-adrenergic blocker. Wheezing is a high-pitched sound that occurs when breathing is obstructed, usually due to asthma or chronic obstructive pulmonary disease (COPD). Nonselective beta-adrenergic blockers can aggravate or cause wheezing by blocking the beta-2 receptors in the lungs, which normally cause bronchodilation (widening of the airways). Therefore, nonselective beta-adrenergic blockers are contraindicated in patients with asthma or COPD.
