Question 1 of 5
The thymus gland role with the immune system is which of the following?
Correct Answer: D
Rationale: The thymus gland plays a crucial role in the immune system as it is primarily responsible for the maturation and differentiation of T lymphocytes (T cells). T cells are essential for cell-mediated immunity and play a key role in recognizing and attacking pathogens such as bacteria, viruses, and cancer cells. The thymus is where immature T cells mature and undergo education to ensure they can distinguish between self and non-self antigens effectively. This process is crucial for the proper functioning of the immune system to protect the body from infections and diseases.
Question 2 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 3 of 5
Which symptoms should the nurse expect to observe during the physical assessment of an adolescent girl with severe weight loss and disrupted metabolism associated with anorexia nervosa?
Correct Answer: B
Rationale: An adolescent girl with severe weight loss and disrupted metabolism associated with anorexia nervosa is likely to exhibit tachycardia (rapid heart rate) and tachypnea (rapid breathing). These symptoms are common manifestations of the body's response to malnutrition and starvation. Tachycardia occurs as a compensatory mechanism to maintain an adequate supply of oxygen to vital organs, while tachypnea helps to eliminate excess carbon dioxide due to metabolic imbalances. It is essential for the nurse to recognize these signs during the physical assessment as they indicate the severity of the condition and the need for immediate intervention to prevent further complications. Dysmenorrhea and oliguria, heat intolerance and increased blood pressure, and lowered body temperature and brittle nails are not typically associated with the physical manifestations of anorexia nervosa.
Question 4 of 5
Spina bifida is one of the possible neural tube defects that can occur during early embryological development. Which of the following definitions most accurately describes meningocele? A.Complete exposure of spinal cord and meninges
Correct Answer: B
Rationale: Meningocele is a type of neural tube defect in which there is herniation of the meninges (protective membranes surrounding the brain and spinal cord) through a defect in the spinal column. This results in the formation of a sac-like protrusion that contains the meninges and cerebrospinal fluid but does not involve the spinal cord itself. In meningocele, the spinal cord remains in its normal position within the spinal canal. This condition is typically associated with spina bifida, a neural tube defect that occurs during early embryological development. Unlike myelomeningocele, which involves both the spinal cord and meninges protruding through the spinal column, meningocele specifically refers to the presence of a sac containing the meninges and spinal fluid without direct involvement of the spinal cord.
Question 5 of 5
Nearly all cervical carcinomas contain human papillomavirus (HPV). Which of the following types is never associated with such malignancy?
Correct Answer: A
Rationale: HPV type 6 is typically associated with low-grade lesions and genital warts, not cervical carcinoma.
