136. Describe how an adenoma of the pituitary gland leads to Cushing's disease.
Chronic stress causes the pituitary gland to produce less ACTH, resulting in Cushing's disease.
An adenoma of the pituitary gland secretes excess adrenocorticotropic hormone (ACTH), which stimulates cortisol production.
An adenoma of the pituitary gland directly produces cortisol, leading to Cushing's disease.
Cushing's disease is caused by a lack of ACTH production from the adrenal glands.

Kussmaul's respirations indicate an increase in oxygen levels in the blood.
Kussmaul's respirations help to increase the exhalation of carbon dioxide, thereby reducing acidity in the blood during metabolic acidosis.
Kussmaul's respirations are a normal breathing pattern that occurs during sleep.
Kussmaul's respirations are a sign of respiratory failure and indicate the need for immediate intervention.
138. If a patient with type 1 diabetes presents with symptoms of nausea, abdominal pain, and confusion, what condition should be suspected and why?
Hyperglycemic Hyperosmolar State (HHS) due to dehydration.
Chronic Kidney Disease due to long-term diabetes complications.
Hypoglycemia due to excessive insulin administration.
Diabetic Ketoacidosis (DKA) due to insulin deficiency and high ketone levels.
139. A patient with metabolic acidosis is showing signs of Kussmaul respirations. The nurse understands this is a compensatory mechanism to:
Reduce bicarbonate levels.
Increase oxygen saturation.
Stabilize heart rate.
Decrease CO2 levels in the blood.
Elevate blood pH.
140. How is Hepatitis C transmitted?
Fecal-Oral
Birth
Contaminated blood
Unprotected intercourse
141. Which of the following is a common mode of transmission for Hepatitis A?
Blood transfusion
Consumption of contaminated food or water
Inhalation of airborne particles
Sexual contact
142. Describe the role of intestinal flora in the synthesis of Vitamin K and its importance for human health.
Intestinal flora are responsible for synthesizing hormones that regulate metabolism.
Intestinal flora synthesize Vitamin K, which is essential for blood clotting and bone health.
Intestinal flora break down carbohydrates, providing energy for the body.
Intestinal flora produce Vitamin D, which helps in calcium absorption.
143. Which body fluids are primarily involved in the transmission of Hepatitis C?
Urine
Saliva
Sweat
Blood
144. If a patient has a random blood glucose level of 200 mg/dL, what would be the next appropriate step in their diabetes management?
Refer the patient for an MRI scan.
Conduct a fasting blood glucose test or an HbA1c test for confirmation.
Schedule a follow-up appointment in one year.
Immediately start insulin therapy.
145. Describe the significance of serum albumin levels in the context of diagnosing malnutrition.
Serum albumin levels indicate protein status and can reflect nutritional deficiencies.
Serum albumin levels assess liver function.
Serum albumin levels are used to evaluate kidney health.
Serum albumin levels measure blood sugar levels.
146. Main clinical presentation of Cushing's syndrome
menorrhagia in females, lethargy
thickening of skin and bones
lower obesity, decreased bp, blood glucose, cholesterol
central obesity-facial rounding, elevated bp, blood glucose, cholesterol
147. What vitamin is primarily synthesized by intestinal flora?
Vitamin K
Vitamin A
Vitamin D
Vitamin C

UPDATE GRADED A+
1. Describe how hyperosmolar hyperglycemic state (HHS) leads to dehydration in the
body.
HHS stimulates the thirst mechanism, preventing dehydration.
HHS causes high blood glucose levels, leading to osmotic diuresis and
subsequent loss of fluids.
HHS causes the kidneys to retain glucose, leading to fluid retention.
HHS increases insulin production, which retains fluid in the body.
2. What are the primary hormones produced by the adrenal gland?
Cortisol, aldosterone, and adrenaline
Estrogen and testosterone
Thyroxine and calcitonin
Insulin and glucagon
