Complications of sustained hypertension include which of the following?
Retinal damage
Stroke
Renal disease
All of the above
The Correct Answer is D
Sustained hypertension can lead to several complications, including damage to the blood vessels in the retina (retinopathy), increased risk of stroke, and damage to the kidneys (renal disease). Other potential complications include heart disease, peripheral arterial disease, and cognitive impairment. It is important to manage hypertension through lifestyle modifications and medication to prevent these complications.

Explanation
The mitral and tricuspid valves are located between the atria and ventricles in the heart, and they open and close to allow blood to flow in one direction through the heart. During diastole, when the heart is relaxed and filling with blood, the mitral and tricuspid valves are open to allow blood to flow from the atria into the ventricles.
Once the ventricles are filled with blood, they begin to contract during systole to pump the blood out to the lungs (right ventricle) and the rest of the body (left ventricle). As the ventricles contract, the pressure within them increases, which causes the mitral and tricuspid valves to be pushed closed by the blood within the ventricles. This closure prevents the backflow of blood into the atria during ventricular contraction (systole).
The chordae tendineae are thin, fibrous cords that connect the mitral and tricuspid valves to the papillary muscles within the ventricles. These structures help to anchor the valves in place during ventricular contraction, and prevent them from prolapsing (bulging back into the atria) and causing regurgitation (backflow of blood).
The trabeculae carneae are muscular ridges within the ventricles that help to increase the force of ventricular contraction, but they do not play a direct role in closing the mitral and tricuspid valves. Similarly, the reduced pressure in the atria during ventricular contraction is due to the fact that blood is being pumped out of the atria and into the ventricles, rather than the atria "pulling" the valves closed.
Correct Answer is D
Explanation
Hemoptysis is the coughing up of blood or bloody secretions from the respiratory tract. It is a sign of a serious condition and should be reported immediately to a healthcare provider. In this case, the patient's cold and cough may have led to irritation and inflammation of the respiratory tract, resulting in hemoptysis.
- Hematemesis: This is the vomiting of blood from the upper gastrointestinal tract, which usually appears bright red or dark brown in color.
- Cyanosis: This is a bluish discoloration of the skin and mucous membranes caused by the presence of deoxygenated hemoglobin in the blood.
- Rhinitis: This is the inflammation of the nasal mucosa, often causing a runny nose, nasal congestion, and sneezing.
