Hypopituitarism is a disorder of the _____________.
- A.
Pituitary gland
- B.
Anterior pituitary gland
- C.
Posterior pituitary gland
Correct Answer
B. Anterior pituitary glandExplanation
Hypopituitarism is a disorder that affects the anterior pituitary gland. The anterior pituitary gland is responsible for producing and releasing several hormones that regulate various bodily functions. When the anterior pituitary gland is not functioning properly, it can lead to a deficiency in one or more hormones, resulting in hypopituitarism. This disorder can cause a range of symptoms depending on which hormones are affected, such as fatigue, weight loss or gain, low blood pressure, and sexual dysfunction.Rate this question:

Panhypopituitarism is a deificiency in _______________.
- A.
PTH
- B.
TSH and ACTH
- C.
All hormones released from the anterior pituitary gland
Correct Answer
C. All hormones released from the anterior pituitary glandExplanation
Panhypopituitarism is a condition characterized by the deficiency of all hormones released from the anterior pituitary gland. This means that the individual with panhypopituitarism will have low levels of hormones such as PTH (parathyroid hormone), TSH (thyroid-stimulating hormone), and ACTH (adrenocorticotropic hormone). This deficiency can lead to various symptoms and complications related to the affected hormones, such as thyroid dysfunction, adrenal insufficiency, and impaired calcium regulation.Rate this question:

Deficiencies in which two horomones produced by the anterior pituitary gland are considered MOST critical?
- A.
ACTH and TSH
- B.
GH and PRL
- C.
None - there are no two hormones produced by the anterior pituitary gland that are more important than the rest
Correct Answer
A. ACTH and TSHExplanation
Deficiencies in ACTH and TSH hormones produced by the anterior pituitary gland are considered most critical because they play crucial roles in regulating the function of other endocrine glands. ACTH stimulates the production of cortisol by the adrenal glands, which is essential for maintaining stress response, metabolism, and immune function. TSH stimulates the production of thyroid hormones, which are vital for regulating metabolism, growth, and development. Deficiencies in these hormones can lead to significant health problems and imbalances in the body.Rate this question:

Pituitary infarction most often occurs _______________.
- A.
As a result of malnutrition.
- B.
As a result of radiation treatment.
- C.
As a result of hemorrhaging in the postpartum phase.
Correct Answer
C. As a result of hemorrhaging in the postpartum phase.Explanation
Pituitary infarction most often occurs as a result of hemorrhaging in the postpartum phase. This is because during childbirth, there is a risk of excessive bleeding, which can lead to a decrease in blood supply to the pituitary gland. This reduced blood flow can cause tissue death and ultimately result in pituitary infarction. Malnutrition and radiation treatment are not commonly associated with pituitary infarction.Rate this question:

Diabetes Insipidus can be caused by _________________.
- A.
A deficiency of ADH synthesis
- B.
Damage to the anterior pituitary gland
- C.
Kidney hyper-sensitivity to ADH (an over-response)
Correct Answer
A. A deficiency of ADH synthesisExplanation
Diabetes Insipidus is a condition characterized by excessive thirst and frequent urination. It occurs due to a deficiency in the synthesis of antidiuretic hormone (ADH) or vasopressin, which is responsible for regulating the body's water balance. When there is a lack of ADH synthesis, the kidneys are unable to properly reabsorb water, leading to the production of large volumes of dilute urine. This can be caused by various factors, such as damage to the posterior pituitary gland, where ADH is produced, or genetic disorders that affect ADH synthesis.Rate this question:

The general "rule of thumb" for I&Os (though doctor may order different) is if urine output is _________________, then report it.
- A.
>100 ml/hr or >250 ml/2hrs
- B.
>250 ml/hr or >400 ml/2hrs
- C.
>200 ml/hr or >500 ml/2hrs
Correct Answer
C. >200 ml/hr or >500 ml/2hrsExplanation
The general "rule of thumb" for I&Os is to report urine output if it is greater than 200 ml/hr or greater than 500 ml/2hrs. This means that if a patient is producing urine at a rate higher than these thresholds, it may indicate a potential issue or imbalance that needs to be addressed. It is important to note that individual patient circumstances and specific doctor's orders may vary, so it is always best to follow the instructions given by the healthcare provider.Rate this question:

400 - 1100
- B.
200-1300
- C.
300-1200
Correct Answer
C. 300-1200Explanation
The normal urine osmolarity is the concentration of solutes in urine, which is typically measured in milliosmoles per kilogram (mOsm/kg). The range of 300-1200 mOsm/kg is considered normal for urine osmolarity. This range allows for variations in fluid intake and output, as well as the body's ability to concentrate or dilute urine as needed.Rate this question:

A patient with a tumor in the hypothalamus comes in complaining of frequent urination, constant thirst, and dizziness when she sits up to get out of bed. Lab work shows a specific gravity of 1.001, urine osmolality of 75, sodium levels of 100, and other electrolytes are low, too. Which of the following would the nurse expect the patient to be diagnosed with?
- A.
Diabetes mellitus type I
- B.
SIADH
- C.
Diabetes insipidu
- D.
Hypothyroidism
Correct Answer
C. Diabetes insipiduExplanation
The patient's symptoms of frequent urination, constant thirst, and low specific gravity and urine osmolality indicate a condition called diabetes insipidus. Diabetes insipidus is a disorder characterized by the inability of the kidneys to conserve water, leading to excessive urination and extreme thirst. The low sodium levels and other electrolyte imbalances further support this diagnosis. Diabetes mellitus type I is characterized by high blood sugar levels, which is not indicated in this case. SIADH is a condition where the body retains too much water, leading to low sodium levels, which is the opposite of what is seen in this patient. Hypothyroidism does not present with these specific symptoms.Rate this question:

As serum volume decreases, osmolarity decreases.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
As serum volume decreases, osmolarity does not necessarily decrease. Osmolarity is a measure of the concentration of solutes in a solution, and it is determined by the number of solute particles present, not the volume of the solution. Therefore, even if the volume of serum decreases, the concentration of solutes may remain the same or even increase, leading to no change or an increase in osmolarity.

D. Nausea and vomiting
E. Weight gain
G. Lung cracklesExplanation
Signs and symptoms of SIADH include headache, increased blood pressure, increased output (I>O), nausea and vomiting, weight gain, and lung crackles. These symptoms occur due to the excessive release of antidiuretic hormone (ADH), which leads to water retention and dilutional hyponatremia. Headache can occur due to cerebral edema caused by water retention. Increased blood pressure can result from fluid overload. Increased output (I>O) refers to the increased urinary output due to the inability of the kidneys to concentrate urine. Nausea and vomiting can occur due to the effects of ADH on the gastrointestinal system. Weight gain is a result of fluid retention. Lung crackles can be heard on auscultation due to pulmonary edema caused by fluid overload.Rate this question:

Doctors often restrict fluids for patients with SIADH.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Patients with SIADH (syndrome of inappropriate antidiuretic hormone secretion) have excessive levels of antidiuretic hormone (ADH) in their bodies, leading to the retention of water by the kidneys. This causes a dilutional hyponatremia, where the sodium levels in the blood become abnormally low. To treat this condition, doctors often restrict fluids in order to prevent further water retention and to help normalize the sodium levels. Therefore, the statement that doctors often restrict fluids for patients with SIADH is true.Rate this question:

Correct Answer(s)
A. High urine osmolarity
C. High specific gravity (urine)
F. Low serum osmolarity
H. Low sodiumExplanation
A patient with SIADH (syndrome of inappropriate antidiuretic hormone) would have high urine osmolarity because the excessive release of ADH causes the kidneys to reabsorb more water, leading to concentrated urine. They would also have high specific gravity in the urine because of the increased concentration. Additionally, they would have low serum osmolarity because the excess water retention dilutes the blood. Finally, they would have low sodium levels because the excessive ADH causes water retention and dilution of sodium in the blood.Rate this question:

Diabetes Insipidus is a condition characterized by the inability of the kidneys to properly regulate fluid balance. In this condition, the body is unable to retain water, leading to excessive urination and thirst. Low urine osmolarity and low specific gravity of urine are expected because the kidneys are unable to concentrate urine. High serum osmolarity is also expected because of the increased concentration of solutes in the blood due to the excessive loss of water. High sodium levels can also be seen due to the dilutional effect caused by the excessive loss of water.Rate this question:

Grave's Disease, which accounts for 80% of cases of hyperthyroidism, is an autoimmune disease in which antibodies are produced that bind to TSH receptors in the thyroid causing TH to be released.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Grave's Disease is indeed an autoimmune disease that causes hyperthyroidism. In this condition, the body produces antibodies that bind to the thyroid-stimulating hormone (TSH) receptors in the thyroid gland. This binding stimulates the release of thyroid hormones (TH), leading to an overactive thyroid gland and the symptoms associated with hyperthyroidism. Therefore, the statement "Grave's Disease, which accounts for 80% of cases of hyperthyroidism, is an autoimmune disease in which antibodies are produced that bind to TSH receptors in the thyroid causing TH to be released" is true.Rate this question:

All of the following can cause hyperthyroidism EXCEPT:
- A.
Excess TSH hormone production
- B.
Inflammation of the thyroid gland
- C.
Pituitary infarction
- D.
Excess T3 secretion
Correct Answer
C. Pituitary infarctionExplanation
Pituitary infarction is not a cause of hyperthyroidism. Hyperthyroidism occurs when there is an excess production of thyroid hormones, such as TSH and T3. Excess TSH hormone production, inflammation of the thyroid gland, and excess T3 secretion can all lead to hyperthyroidism. However, pituitary infarction refers to the death of cells in the pituitary gland due to a lack of blood supply, which would not directly cause hyperthyroidism.Rate this question:

In Grave's Disease, labs will show _______ TSH levels because the negative feedback mechanism is ___________.
- A.
Low; malfunctioning
- B.
Low; functioning properly
- C.
High; malfunctioning
- D.
High; functioning properly
Correct Answer
B. Low; functioning properlyExplanation
In Grave's Disease, the labs will show low TSH levels because the negative feedback mechanism is functioning properly. Grave's Disease is an autoimmune disorder that causes the thyroid gland to overproduce thyroid hormones. The excessive levels of thyroid hormones in the body signal the pituitary gland to decrease the production of TSH, which is responsible for stimulating the thyroid gland. Therefore, in Grave's Disease, the low TSH levels indicate that the negative feedback mechanism is functioning properly by suppressing the production of TSH in response to high levels of thyroid hormones.Rate this question:

Exophthalmos is a condition in which ______________.
- A.
The thalamus is protruding due to a tumor pushing from below it in the pituitary gland.
- B.
The eyes are pushed forward due to "fat pads" that grow behind the eyeball.
- C.
The thyroid grows abnormally large.
Correct Answer
B. The eyes are pushed forward due to "fat pads" that grow behind the eyeball.Explanation
Exophthalmos is a condition in which the eyes are pushed forward due to "fat pads" that grow behind the eyeball. This condition can be caused by various factors, such as thyroid eye disease, orbital inflammation, or tumors. The protrusion of the eyes can result in a bulging appearance and can cause symptoms such as dryness, irritation, and difficulty closing the eyelids fully. Treatment options depend on the underlying cause and may include medications, surgery, or management of the underlying condition.Rate this question:

Correct Answer(s)
A. Bradycardia
D. Goiter
E. Depression
G. Cold intolerance
I. Fatigue
K. Decreased free T4
L. Sluggish DTRsExplanation
Hypothyroidism is a condition in which the thyroid gland does not produce enough thyroid hormone. Bradycardia, or a slow heart rate, is a sign of hypothyroidism as the lack of thyroid hormone can slow down the heart rate. Goiter, an enlargement of the thyroid gland, can occur in hypothyroidism due to the thyroid gland trying to compensate for the lack of hormone production. Depression is a common symptom of hypothyroidism as low levels of thyroid hormone can affect mood. Cold intolerance is a symptom of hypothyroidism as the lack of thyroid hormone can affect the body's ability to regulate temperature. Fatigue is a common symptom of hypothyroidism as low levels of thyroid hormone can slow down bodily functions. Decreased free T4 levels indicate low thyroid hormone levels, which is a sign of hypothyroidism. Sluggish deep tendon reflexes (DTRs) can occur in hypothyroidism as the lack of thyroid hormone can affect nerve conduction.Rate this question:
