The nurse provides care for a client who reports burning pain, which is worse at night, in both feet. The client states the pressure of the sheets on the feet is "unbearable". Which reason is the most common cause of this type of pain?
Liver failure
Diabetes mellitus
Mercury toxicity
Vitamin B12 deficiency
The Correct Answer is B
Choice A reason: Liver failure is not the most common cause of this type of pain because it is a condition where the liver loses its ability to perform its vital functions, such as detoxifying the blood, producing bile, and metabolizing nutrients. Liver failure can cause symptoms such as jaundice, ascites, or bleeding, but it does not usually cause burning pain in the feet.
Choice B reason: Diabetes mellitus is the most common cause of this type of pain because it is a condition where the blood glucose level is too high, either due to insufficient insulin production or reduced insulin sensitivity. Diabetes mellitus can cause damage to the nerves, especially in the peripheral areas, such as the feet, which is called diabetic neuropathy. Diabetic neuropathy can cause symptoms such as burning pain, numbness, or tingling in the feet, which can worsen at night or with pressure.
Choice C reason: Mercury toxicity is not the most common cause of this type of pain because it is a condition where the body is exposed to high levels of mercury, which is a toxic metal that can be found in some fish, dental fillings, or thermometers. Mercury toxicity can cause damage to the nervous system, causing symptoms such as tremors, memory loss, or mood changes, but it does not usually cause burning pain in the feet.
Choice D reason: Vitamin B12 deficiency is not the most common cause of this type of pain because it is a condition where the body does not have enough vitamin B12, which is a nutrient that is essential for the production of red blood cells and the maintenance of the nervous system. Vitamin B12 deficiency can cause symptoms such as anemia, fatigue, or weakness, but it does not usually cause burning pain in the feet.

Correct Answer is C
Explanation
Choice A reason: Initiates the fibrinolytic process in the arteries is not a role of inflammation in the development of atherosclerosis, but a protective mechanism against it. Fibrinolysis is the breakdown of blood clots by enzymes such as plasmin. It prevents the formation of thrombi that can occlude the arteries and cause ischemia.
Choice B reason: Decreases highly sensitive C-reactive protein (hsCRP) levels is not a role of inflammation in the development of atherosclerosis, but an indicator of it. hsCRP is a marker of systemic inflammation that is produced by the liver in response to cytokines. It is elevated in patients with atherosclerosis and correlates with the risk of cardiovascular events.
Choice C reason: Damages the endothelium of the arteries is the main role of inflammation in the development of atherosclerosis. Endothelial injury exposes the subendothelial layer to the blood, which triggers the adhesion of monocytes and platelets. Monocytes differentiate into macrophages and engulf oxidized low-density lipoproteins (LDL), forming foam cells. Foam cells accumulate in the intima and form fatty streaks, which are the earliest lesions of atherosclerosis.
Choice D reason: Causes diffuse arterial vasoconstriction is not a role of inflammation in the development of atherosclerosis, but a consequence of it. Atherosclerosis narrows the lumen of the arteries and reduces the blood flow to the tissues. This causes ischemia, which stimulates the release of vasoconstrictors such as angiotensin II and endothelin. Vasoconstriction further worsens the ischemia and increases the blood pressure.
Correct Answer is B
Explanation
Choice A reason: Herpes simplex 2 virus is not the microorganism that causes infectious mononucleosis, but a different type of herpes virus that causes genital herpes. Genital herpes is a sexually transmitted infection that causes painful blisters and ulcers in the genital area.
Choice B reason: Epstein-Barr virus is the best explanation for the microorganism that causes infectious mononucleosis. Epstein-Barr virus is a type of herpes virus that infects the B lymphocytes, which are a type of white blood cells. It causes infectious mononucleosis, also known as mono or the kissing disease, which is a common infection that causes fever, sore throat, swollen lymph nodes, and fatigue.
Choice C reason: Hepatitis C virus is not the microorganism that causes infectious mononucleosis, but a different type of virus that causes hepatitis C. Hepatitis C is a blood-borne infection that affects the liver. It causes inflammation, scarring, and cirrhosis of the liver, which may lead to liver failure or cancer.
Choice D reason: Rubella virus is not the microorganism that causes infectious mononucleosis, but a different type of virus that causes rubella. Rubella, also known as German measles, is a mild infection that causes a rash, fever, and swollen glands. It is preventable by vaccination and can be dangerous for pregnant women, as it may cause birth defects or miscarriage.
