A nurse is teaching a patient about risk factors for hypertension.
Which of the following should the nurse include as non-modifiable risk factors?
Stress.
Obesity.
Gender.
Sodium intake.
The Correct Answer is C
Choice A rationale
Stress is considered a modifiable risk factor because individuals can adopt various coping mechanisms and lifestyle changes to reduce its impact on the body. Chronic stress triggers the sympathetic nervous system, leading to sustained elevations in cortisol and adrenaline, which increase blood pressure. Through techniques such as mindfulness, cognitive behavioral therapy, or environmental adjustments, a patient can successfully lower their stress levels and subsequently reduce their risk for hypertension.
Choice B rationale
Obesity is a modifiable risk factor that is directly linked to metabolic and cardiovascular health. Excessive adipose tissue increases systemic vascular resistance and places a higher demand on the heart to pump blood. However, weight can be managed and reduced through a combination of caloric restriction and increased physical energy expenditure. Achieving a healthy Body Mass Index significantly lowers the mechanical and chemical strain on the circulatory system.
Choice C rationale
Gender is a non-modifiable risk factor because it is determined by biological sex chromosomes and the resulting hormonal profile established at birth. Statistical data shows that men often develop hypertension earlier in life compared to premenopausal women, largely due to the protective effects of estrogen. Since an individual cannot change their biological sex or the innate hormonal framework they were born with, it is classified as a permanent risk characteristic.
Choice D rationale
Sodium intake is a modifiable risk factor because it is entirely dependent on an individual's nutritional choices and eating habits. High sodium consumption leads to water retention and increased extracellular fluid volume, which directly raises blood pressure levels. By adhering to a low-sodium diet, such as the DASH diet, patients can effectively decrease the osmotic pressure within their vessels. This behavioral change is a cornerstone of non-pharmacological hypertension management.

Correct Answer is ["A","B","E"]
Explanation
Choice A rationale
Bradykinesia is a fundamental component of the Parkinson's triad and refers to the generalized slowness of movement. This occurs due to the depletion of dopamine in the substantia nigra, which disrupts the basal ganglia's ability to facilitate motor output. Patients experience difficulty initiating movements and a reduction in automatic motions, such as swinging the arms while walking. It significantly impacts daily activities and is essential for a clinical diagnosis of the neurodegenerative disease.
Choice B rationale
Resting tremor is a classic sign often described as a pill-rolling motion of the hands. It typically occurs when the limb is relaxed and disappears during purposeful movement or sleep. This tremor results from the rhythmic firing of neurons in the subthalamic nucleus and globus pallidus due to the loss of dopaminergic inhibition. While not all patients exhibit a tremor, it is one of the most recognizable and frequent symptoms included in the hallmark diagnostic triad.
Choice C rationale
Memory loss and cognitive decline can occur in Parkinson's disease, particularly in the later stages, but they are not part of the "classic triad" used for initial diagnosis. Dementia associated with Parkinson's is a separate clinical consideration from the primary motor symptoms. The triad focuses specifically on motor dysfunction resulting from basal ganglia pathology. Memory issues are more central to Alzheimer's disease or Lewy body dementia rather than being a defining primary motor sign.
Choice D rationale
Loss of sensation is not a characteristic feature of Parkinson's disease. Parkinson's is primarily a motor system disorder affecting the extrapyramidal tract. While some patients may report vague aches or pains, true sensory loss involving touch, temperature, or proprioception suggests a peripheral neuropathy or a lesion in the sensory cortex or spinal cord. Sensory pathways remain intact in Parkinson's, as the underlying pathology is concentrated in the dopamine-producing cells of the midbrain.
Choice E rationale
Cogwheel rigidity is the third component of the classic triad. It refers to a specific type of muscle stiffness where there is a jerky, lead-pipe resistance to passive limb movement. This "cogwheel" sensation is thought to be the combination of basic rigidity and an underlying tremor. It affects both agonist and antagonist muscles equally. This increased muscle tone contributes to the characteristic stooped posture and masked facies seen in individuals progressing through the stages of Parkinson's.
Correct Answer is A
Explanation
Choice A rationale
The tricuspid valve is one of the two atrioventricular valves, specifically located on the right side of the heart. Its primary function is to allow blood to flow from the right atrium into the right ventricle during diastole while preventing the backflow of blood into the atrium during ventricular systole. It consists of three leaflets or cusps. Understanding this anatomy is crucial for assessing right-sided heart function and identifying murmurs associated with tricuspid regurgitation or stenosis.
Choice B rationale
The valve located between the left ventricle and the aorta is the aortic valve, which is a semilunar valve. It opens during ventricular systole to allow oxygenated blood to be pumped into the systemic circulation and closes during diastole to prevent blood from leaking back into the left ventricle. This is a high-pressure valve on the left side of the heart, whereas the tricuspid valve is a lower-pressure valve located on the right side.
Choice C rationale
The valve located between the right ventricle and the pulmonary artery is the pulmonary valve, another semilunar valve. This valve facilitates the flow of deoxygenated blood toward the lungs for gas exchange while preventing backflow into the right ventricle during relaxation. While it is on the right side of the heart, it is not the tricuspid valve; the tricuspid valve is positioned upstream of the pulmonary valve between the atrium and ventricle.
Choice D rationale
The valve located between the left atrium and the left ventricle is the mitral valve, also known as the bicuspid valve. Like the tricuspid valve, it is an atrioventricular valve, but it is situated on the left side of the heart and consists of only two leaflets. It ensures the one-way flow of oxygen-rich blood into the left ventricle. Confusing the tricuspid and mitral valves is a common error, but they serve opposite sides of the heart.
