A staff nurse is teaching a client who has secondary hypothyroidism about the disease process. The client asks the nurse what causes secondary hypothyroidism. Which of the following responses should the nurse make?
"It is caused by the overproduction of T3, T4, and calcitonin by the thyroid gland."
"It is caused by the lack of production of adrenocorticotropic hormone by the pituitary gland."
"It is caused by the lack of production of thyroid stimulating hormone by the pituitary gland."
"It is caused by the lack of production of aldosterone by the adrenal gland."
The Correct Answer is C
A. Secondary hypothyroidism is characterized by insufficient production of thyroid hormones (T3 and T4) due to inadequate stimulation from the pituitary gland, not due to overproduction. Overproduction of thyroid hormones would typically be associated with hyperthyroidism, not hypothyroidism.
B. Adrenocorticotropic hormone (ACTH) stimulates the adrenal glands to produce cortisol. A deficiency in ACTH would lead to adrenal insufficiency or Addison's disease, not secondary hypothyroidism.
Secondary hypothyroidism specifically involves a deficiency in thyroid-stimulating hormone (TSH), not ACTH.
C. Secondary hypothyroidism is caused by inadequate production of thyroid-stimulating hormone (TSH) by the pituitary gland. TSH is necessary for stimulating the thyroid gland to produce thyroid hormones (T3 and T4). When the pituitary gland does not produce enough TSH, the thyroid gland is not adequately stimulated, leading to low levels of thyroid hormones in the blood.
D. Aldosterone is a hormone produced by the adrenal glands that helps regulate sodium and potassium levels, as well as blood pressure. A deficiency in aldosterone is associated with conditions such as
Addison’s disease or primary adrenal insufficiency, not secondary hypothyroidism. Secondary
hypothyroidism specifically relates to issues with TSH production, not aldosterone.

Correct Answer is B
Explanation
A. Tertiary prevention focuses on managing the consequences of an existing disease or condition. The hepatitis B vaccination prevents the disease from occurring in the first place.
B. Primary prevention aims to prevent the occurrence of a disease or condition. The hepatitis B vaccination is a classic example of primary prevention, as it protects individuals from contracting the virus.
C. Secondary prevention involves early detection and treatment of a disease or condition. The hepatitis B vaccination is not intended for the early detection or treatment of an existing infection.
D. The hepatitis B vaccination is not a treatment for hepatitis B. It is a preventative measure to protect individuals from contracting the virus.

Explanation
Peritonitis
Peritonitis is an infection of the peritoneum (the lining of the abdominal cavity), often related to peritoneal dialysis. It can present with abdominal pain, fever, rigidity, and rebound tenderness,
consistent with the client’s symptoms. Cloudy effluent is also a common sign of peritoneal dialysis- related peritonitis.
Peritoneal dialysis
Peritoneal dialysis is a type of dialysis that uses the peritoneum (abdominal lining) to filter blood. If there is an issue with the dialysis process, it could lead to complications such as peritonitis. This is consistent with the client's symptoms, such as abdominal pain, fever, nausea, vomiting, and cloudy effluent.
