Question 1 of 5
The following are known to be causes of hepatitis except:
Correct Answer: C
Rationale: Hepatitis is inflammation of the liver, and it can be caused by viruses, toxins, or chemicals and drugs. Bacteria, however, do not typically cause hepatitis. Common viral causes of hepatitis include hepatitis A, B, and C. Toxins like alcohol and certain medications, as well as exposure to chemicals, can also lead to hepatitis. Therefore, bacteria are not considered one of the primary causes of hepatitis.
Question 2 of 5
A client was brought to the school clinic wuth severe, constant, localized abdominal pain. Abdominal muscles are rigid, and rebound tenderness is present. Peritonitis is suspected. The client is hypotensive and tachycardic. The nursing diagnosis most appropriate to the client's signs/symptoms is:
Correct Answer: A
Rationale: The client's signs and symptoms point towards a diagnosis of peritonitis, which is an inflammation of the peritoneum lining the abdominal cavity. The presence of severe, constant abdominal pain, rigid abdominal muscles, rebound tenderness, hypotension, and tachycardia are all indicative of peritonitis. These symptoms are typically seen when there is an infection or inflammation in the abdominal cavity, leading to fluid shifting from the intravascular space to the peritoneal cavity. This shifting of fluid results in hypovolemia, causing hypotension and tachycardia.
Question 3 of 5
JR is admitted to the medical-surgical unit because of a diagnosis of nephritic syndrome. What is the hallmark of this syndrome?
Correct Answer: C
Rationale: Nephritic syndrome is characterized by inflammation of the glomeruli in the kidneys, leading to proteinuria, hematuria, and decreased kidney function. The hallmark symptom of nephritic syndrome is edema, which occurs due to the loss of proteins in the urine as a result of damaged glomeruli. The loss of proteins leads to a decrease in colloid osmotic pressure, causing fluid to leak out from the blood vessels into the surrounding tissues, resulting in edema. Osmotic diuresis, hypolipidemia, and hyperproteinemia are not typically associated with nephritic syndrome.
Question 4 of 5
The nurse expects to note an elevated serum glucose level in a client with hyperosmolar hyperglycemic nonketonic syndrome (HHNS). Which other laboratory finding should the nurse anticipate?
Correct Answer: D
Rationale: Hyperosmolar hyperglycemic nonketonic syndrome (HHNS) is characterized by extremely elevated blood glucose levels without significant ketosis. Unlike diabetic ketoacidosis (DKA), patients with HHNS usually do not have high levels of ketone bodies in their blood or urine. Therefore, the nurse should anticipate below-normal serum potassium levels in a client with HHNS, as hyperglycemia can lead to profound potassium losses through osmotic diuresis. Monitoring and treating electrolyte imbalances, including hypokalemia, are crucial in managing HHNS. It is important to correct these imbalances promptly to prevent further complications.
Question 5 of 5
The nurse is assessing a client with possible Cushing's syndrome. In a client with Cushing's syndrome, the nurse would expect to find:
Correct Answer: C
Rationale: Cushing's syndrome is a disorder characterized by excessive levels of cortisol in the body. One of the classic physical manifestations of Cushing's syndrome is the accumulation of adipose (fat) tissue in specific areas, such as the trunk (central obesity) and dorsocervical area (referred to as a "buffalo hump"). This redistribution of body fat is a key feature in Cushing's syndrome. The thick, coarse skin is commonly seen in conditions like acromegaly, not in Cushing's syndrome. Weight gain in the arms and legs is not a typical finding in Cushing's syndrome. Additionally, hypertension, rather than hypotension, is more commonly associated with excess cortisol levels in Cushing's syndrome.
