PTH stands for.....
- A.
Parathyroid Hormone
- B.
Pituitary Hormone
- C.
Perfect Timing Hormone (If you don't have it you're always late)
- D.
Parathymus Hormone
Correct Answer
A. Parathyroid HormoneExplanation
PTH stands for Parathyroid Hormone. The parathyroid hormone is a hormone produced by the parathyroid glands, which are located in the neck. This hormone helps regulate the levels of calcium and phosphate in the body. It increases the release of calcium from bones into the bloodstream, enhances the absorption of calcium in the intestines, and reduces the excretion of calcium in the urine. Overall, PTH plays a crucial role in maintaining the balance of calcium in the body, which is essential for proper functioning of nerves, muscles, and bones.Rate this question:

The parathyroid gland _______ blood calcium levels by releasing _____.
- A.
Increases, PTH
- B.
Decreases, PTH
- C.
Increases, Calcitonin
- D.
Decreases, Calcitonin
Correct Answer
A. Increases, PTHExplanation
The parathyroid gland increases blood calcium levels by releasing parathyroid hormone (PTH). PTH acts on the bones, kidneys, and intestines to increase the release of calcium from the bones, enhance the reabsorption of calcium in the kidneys, and stimulate the absorption of calcium in the intestines. This helps to maintain the appropriate levels of calcium in the blood.Rate this question:

Nutritional Secondary Hyperparathyroidism is common in ________.
- A.
Young, growing cats
- B.
Old, aging cats
- C.
Young, growing dogs
- D.
Old, aging dogs
Correct Answer
A. Young, growing catsExplanation
Nutritional Secondary Hyperparathyroidism is common in young, growing cats because they have higher calcium requirements during their rapid growth phase. If their diet lacks sufficient calcium, their body will mobilize calcium from the bones, leading to imbalances in calcium and phosphorus levels. This can result in the overstimulation of the parathyroid gland, leading to the development of Nutritional Secondary Hyperparathyroidism. This condition is less common in old, aging cats as their calcium requirements decrease with age.Rate this question:

Nutritional Secondary Hyperparathyroidism (NSH) is caused by _____.
- A.
Low calcium, high phosphorus diets
- B.
High calcium, low phosphorus diets
- C.
High protein diets
- D.
Low protein diets
Correct Answer
A. Low calcium, high pHospHorus dietsExplanation
Nutritional Secondary Hyperparathyroidism (NSH) is caused by low calcium, high phosphorus diets. This condition occurs when there is an imbalance between calcium and phosphorus levels in the diet. A diet that is low in calcium and high in phosphorus can lead to decreased calcium absorption and increased phosphorus levels in the blood. This imbalance triggers the release of parathyroid hormone, which causes the bones to release calcium into the blood, leading to bone demineralization and the development of NSH.Rate this question:
-
- 9.
What sort of diets usually have low calcium and high phosphorus?
- A.
All meat diet
- B.
All dry food diet
- C.
Organic food diet
- D.
Raw food diet
Correct Answer
A. All meat dietExplanation
An all meat diet usually has low calcium and high phosphorus because meat is generally low in calcium and high in phosphorus compared to other food sources. Calcium is essential for maintaining strong bones and teeth, while phosphorus is important for energy production and cell function. Therefore, a diet that consists solely of meat may not provide adequate calcium for the body's needs, potentially leading to calcium deficiency and related health issues.Rate this question:

Hyperparathyroidism is marked by the increased production of _________
- A.
PTH
- B.
TRH
- C.
TSH
- D.
GH
Correct Answer
A. PTHExplanation
Hyperparathyroidism is a condition characterized by the excessive production of parathyroid hormone (PTH). PTH plays a crucial role in regulating calcium levels in the body. When there is an overproduction of PTH, it can lead to elevated levels of calcium in the blood, which can have various effects on the body, such as weakening of the bones, kidney stones, and gastrointestinal issues. Therefore, the correct answer is PTH.Rate this question:

An increased concentration of circulating ____ in the bloodstream is observable in patients with hyperparathyroidism.
- A.
Thyroxine-a, T4
- B.
Thyroxine-b, T4
- C.
Thyroxin-a, T3
- D.
Thyroixin-b, T3
Correct Answer
A. Thyroxine-a, T4Explanation
In patients with hyperparathyroidism, there is an increased concentration of circulating Thyroxine-a, also known as T4, in the bloodstream. This hormone is produced by the thyroid gland and plays a crucial role in regulating metabolism. Hyperparathyroidism is a condition characterized by the overactivity of the parathyroid glands, which can lead to an imbalance of various hormones in the body, including T4. Therefore, an increased concentration of T4 can be observed in patients with hyperparathyroidism.Rate this question:
-

Hypoparathyroidism is primarily seen in ____.
- A.
Dogs
- B.
Cats
- C.
Kittens from 12 weeks of age
- D.
Wobbly hedgehogs
Correct Answer
A. DogsExplanation
Hypoparathyroidism is primarily seen in dogs. This condition occurs when the parathyroid glands, which are responsible for regulating calcium levels in the body, do not produce enough parathyroid hormone. Dogs with hypoparathyroidism may experience symptoms such as muscle tremors, weakness, seizures, and difficulty breathing. Treatment typically involves supplementation with calcium and vitamin D to help regulate calcium levels in the body. While hypoparathyroidism can occur in other animals, such as cats, the question specifically asks for the primary species affected, which is dogs.Rate this question:
-
- 14.
Hypoparathyroidism is marked by the decreased production of ______.
- A.
PTH
- B.
PTO
- C.
TRH
- D.
PYT
Correct Answer
A. PTHExplanation
Hypoparathyroidism is a condition characterized by the decreased production of parathyroid hormone (PTH). The parathyroid glands, located in the neck, are responsible for producing PTH, which helps regulate calcium and phosphorus levels in the body. When there is a decrease in PTH production, it can lead to low levels of calcium in the blood, resulting in symptoms such as muscle cramps, tingling sensations, and weak bones. Therefore, PTH is the correct answer as it is the hormone that is decreased in hypoparathyroidism.Rate this question:

Neuromuscular excitability is observed in dogs with hypoparathyroidism.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Neuromuscular excitability refers to the ability of the nerves and muscles to respond to stimuli. Hypoparathyroidism is a condition characterized by low levels of parathyroid hormone, which can lead to imbalances in calcium and phosphorus levels. In dogs with hypoparathyroidism, the low levels of parathyroid hormone can cause increased neuromuscular excitability, leading to symptoms such as muscle twitching, tremors, and seizures. Therefore, the statement that neuromuscular excitability is observed in dogs with hypoparathyroidism is true.Rate this question:

Parathyroid Function Tests: PTH is tested for hyper or hypoparathyroidism in patients with _______.
- A.
Hypocalcemia or Hypercalcemia
- B.
Hypoglycemia or Hyperglycemia
- C.
Hypophosphatemia or Hyperphosphatemia
- D.
Neuromuscular excitibility and PU/PD
Correct Answer
A. Hypocalcemia or HypercalcemiaExplanation
Parathyroid Function Tests are used to determine the levels of parathyroid hormone (PTH) in the blood. PTH is responsible for regulating calcium levels in the body. Therefore, these tests are performed in patients with symptoms or suspected cases of either hypocalcemia (low calcium levels) or hypercalcemia (high calcium levels). By measuring PTH levels, healthcare providers can assess the functioning of the parathyroid glands and diagnose hyperparathyroidism or hypoparathyroidism.Rate this question:
