NURS 223 EXAM 3 ACTUAL EXAM WITHCOMPLETE QUESTIONS AND CORRECT
ANSWERS RATED A+
The physician is assessing a client with a preliminary diagnosis of
endocrine disorder. Further assessment findings identify
abnormalities with emotion, pain, body temperature, and neural
input. The physician determines the need to further assess the:
a) Cerebellum
b) Hypothalamus
c) Anterior pituitary
d) Cerebral cortex Correct Answer b) Hypothalamus
The hypothalamus is the coordinating center of the brain for
endocrine, behavioral, and autonomic nervous system function. It
is at the level of the hypothalamus that emotion, pain, body
temperature, and other neural input are communicated to the
endocrine system. The anterior pituitary regulates several
physiological processes, including stress, growth, reproduction,
and lactation. The cerebellum is involved in motor control, and the
cerebral cortex is associated with sensory, motor, and association
Which gland is often referred to as the master gland because it
secretes many hormones?
a) Pituitary
b) Thyroid
c) Hypothalamus
d) Pancreas Correct Answer a) Pituitary
The pituitary gland has been called the master gland because its
hormones control the functions of many target glands and cells.
That is not a term used to refer to the other options.
,While discussing the regulation of hormone levels, the instructor
gives an example of hormones regulated by feedback
mechanisms. Which example of this regulation is best?
a) When a female is thinking about getting pregnant, the body
knows to release female sex hormones in greater proportion than
usual.
b) Following a meal that was high in carbohydrates, a person's
blood glucose elevates, which stimulates the release of insulin
from the pancreas.
c) In children, the body knows to release growth hormones while
they are sleeping instead of when they are awake and running
around.
d) When a person's body pH is decreasing, the stomach lining
becomes more acidic to offset this. Correct Answer b) Following a
meal that was high in carbohydrates, a person's blood glucose
elevates, which stimulates the release of insulin from the
pancreas.
The levels of hormones such as insulin and antidiuretic hormone
(ADH) are regulated by feedback mechanisms that monitor
substances such as glucose (insulin) and water (ADH) in the
body. None of the other examples are accurate examples of this
feedback mechanism.
A client has developed a tumor of the posterior pituitary gland.
The client is at risk for problems with secretions of:
a) Growth hormone-releasing hormone (GHRH) and dopamine
b) Adrenocorticotropic hormone (ACTH) and vasopressin
c) Somatostatin and prolactin
d) Antidiuretic hormone (ADH) and oxytocin Correct Answer d)
Antidiuretic hormone (ADH) and oxytocin
The posterior pituitary secretes ADH and oxytocin/vasopressin,
while the anterior pituitary secretes the hormones listed in the
other choices.
,Select the statement that best explains the function of hormone
receptors.
a) Hormone receptors produce antibodies to block certain
hormones from entering the cell.
b) Hormone receptors recognize a specific hormone and
translate the signal into a cellular response.
c) Hormone receptors respond to decreasing hormone levels by
producing a decrease in receptor numbers.
d) Hormone receptors are located within the red blood cells and
carry hormones to the target cells. Correct Answer b) Hormone
receptors recognize a specific hormone and translate the signal
into a cellular response.
Hormone receptors are complex molecular structures that are
located either on the surface of or inside target cells. The function
of these receptors is to recognize a specific hormone and
translate the hormonal signal into a cellular response. The other
choices are not true
When caring for a client with anemia and a decrease in red blood
cells (RBCs), the nurse recognizes which of these hormones will
stimulate the bone marrow to produce additional RBCs?
a) Somatostatin
b) Erythropoietin
c) Cortisol
d) Atrial natriuretic peptide Correct Answer b) Erythropoietin
Erythropoietin is made in the kidney and stimulates
erythropoiesis, production of RBCs in the bone marrow
Hormones are usually divided into categories according to their
structure. The release of epinephrine would be classified as:
a) Peptides and polypeptides
b) Steroids
, c) Amines and amino acids
d) Proteins Correct Answer c) Amines and amino acids
Hormones are divided into three categories according to their
structures: amines and amino acids; polypeptides, proteins, and
glycoproteins; and steroids. The amine and amino acid hormones
include norepinephrine and epinephrine, which are derived from a
single amino acid (i.e., tyrosine). The peptide, polypeptide,
protein, and glycoprotein hormones can be as small as
thyrotropin-releasing hormone (TRH), which contains three amino
acids, and as large, and as large and complex as growth hormone
(GH) and follicle-stimulating hormone (FSH). Steroid hormones,
such as the glucocorticoids, are derivatives of cholesterol.
Select the category of hormones that include norepinephrine and
epinephrine.
a) Glycoproteins
b) Steroids
c) Peptides
d) Amines and amino acids Correct Answer d) Amines and amino
acids
Hormones can be divided into three categories: (1) amines and
amino acids; (2) peptides, polypeptides, proteins, and
glycoproteins; and (3) steroids. The amines include
norepinephrine and epinephrine. The second category, the
peptides, includes polypeptides, proteins, and glycoproteins. The
third category consists of the steroid hormones, which are
derivatives of cholesterol.
Which of the following manifestations would a nurse expect when
assessing a child with insufficient growth hormone (GH)
secretion?
a) Lower blood calcium levels
b) Increased susceptibility to infection
