A patient with left heart failure starts to have a cough and dyspnea. Pulmonary symptoms common to left heart failure are a result of:
Decreased cardiac output.
Bronchoconstriction.
Inflammatory pulmonary edema.
Pulmonary vascular congestion.
The Correct Answer is D
Choice A reason: This is not the cause of pulmonary symptoms in left heart failure. Decreased cardiac output is a consequence of left heart failure, which affects the perfusion of vital organs and tissues.
Choice B reason: This is not the cause of pulmonary symptoms in left heart failure. Bronchoconstriction is a feature of asthma and chronic obstructive pulmonary disease (COPD), which affect the airways and cause wheezes and shortness of breath.
Choice C reason: This is not the cause of pulmonary symptoms in left heart failure. Inflammatory pulmonary edema is a type of non-cardiogenic pulmonary edema, which occurs when the alveolar-capillary membrane is damaged by an inflammatory process, such as pneumonia or sepsis.
Choice D reason: This is the correct cause of pulmonary symptoms in left heart failure. Pulmonary vascular congestion is a result of increased pressure in the pulmonary circulation, which occurs when the left ventricle fails to pump blood effectively to the aorta and the rest of the body. This causes fluid to leak into the alveoli and interstitial spaces, leading to cough, dyspnea, crackles, and pink frothy sputum.

Correct Answer is D
Explanation
Choice A reason: Potassium is not restricted in the management of high blood pressure. In fact, potassium can help lower blood pressure by balancing the effects of sodium and relaxing the blood vessel walls.
Choice B reason: Magnesium is not restricted in the management of high blood pressure. Magnesium can also help lower blood pressure by regulating the calcium channels and improving the endothelial function.
Choice C reason: Calcium is not restricted in the management of high blood pressure. Calcium can also help lower blood pressure by inhibiting the renin-angiotensin system and reducing the vascular resistance.
Choice D reason: Sodium is restricted in the management of high blood pressure. Sodium can increase blood pressure by retaining water in the body and increasing the blood volume and pressure.
Correct Answer is B
Explanation
Choice A reason: This is not what will happen when a person is hypotensive. Baroreceptors are sensory receptors that detect changes in blood pressure. When a person is hypotensive, the baroreceptors are more active, not less, and they send signals to the brain to increase the blood pressure.
Choice B reason: This is what will happen when a person is hypotensive. SNS stands for sympathetic nervous system, which is the part of the autonomic nervous system that prepares the body for fight or flight response. When a person is hypotensive, the SNS is activated to increase the heart rate, contractility, and vasoconstriction, which all raise the blood pressure.
Choice C reason: This is not what will happen when a person is hypotensive. Person will be bradycardic means that the person will have a slow heart rate, usually below 60 beats per minute. When a person is hypotensive, the opposite will happen, as the heart rate will increase to compensate for the low blood pressure.
Choice D reason: This is not what will happen when a person is hypotensive. SNS is suppressed means that the sympathetic nervous system is inhibited or reduced in activity. When a person is hypotensive, the SNS is not suppressed, but rather stimulated, to increase the blood pressure.
