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 B
Explanation
Choice A reason: Serum glucose 158 mg/dL (8.77 mmol/L) is not the most significant observation for an acute adrenal crisis, but a mild elevation of blood sugar. A mild elevation of blood sugar may occur due to stress, infection, medication, or diet, among other factors. It does not indicate a severe deficiency of adrenal hormones, which is the cause of an acute adrenal crisis.
Choice B reason: Blood pressure 98/52 mm Hg is the most significant observation for an acute adrenal crisis, as it indicates a condition called hypotension. Hypotension is a low blood pressure that may cause dizziness, fainting, shock, or organ failure. It is a sign of an acute adrenal crisis, which is a life-threatening emergency that occurs when the adrenal glands fail to produce enough cortisol and aldosterone. Cortisol and aldosterone are hormones that regulate blood pressure, blood sugar, and electrolyte balance.
Choice C reason: Weight gain 3 pounds (1.36 kg) in 24 hours is not the most significant observation for an acute adrenal crisis, but a possible sign of fluid retention. Fluid retention may occur due to heart failure, kidney disease, liver disease, or medication, among other causes. It does not indicate a severe deficiency of adrenal hormones, which is the cause of an acute adrenal crisis.
Choice D reason: Insomnia and restlessness are not the most significant observations for an acute adrenal crisis, but possible symptoms of anxiety, stress, or hyperthyroidism. Anxiety, stress, and hyperthyroidism may cause difficulty sleeping, nervousness, or agitation, among other effects. They do not indicate a severe deficiency of adrenal hormones, which is the cause of an acute adrenal crisis.
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.
