Which symptom is not a clinical manifestation of croup?
a. Rhinorrhea
b. Sore throat
c. Low-grade fever
d. Barking cough
e. Coarse rhonchi
e. Coarse rhonchi
Typically, a prodrome of rhinorrhea, sore throat, and low-grade fever is exhibited for a few days with
croup. The child then develops the characteristic harsh (seal-like) barking cough, hoarse voice, and
inspiratory stridor.
What are the clinical manifestations of bacterial pneumonia in children? (Select all that apply.)
a. Fever with chills
b. Productive cough
c. Dyspnea
d. Respiratory alkalosis
e. Malaise
a. Fever with chills
b. Productive cough
c. Dyspnea
e. Malaise
What imbalance lessens the rate of secretion of parathyroid hormone (PTH)?
a. Increased serum calcium levels
1|Page
,b. Decreased serum magnesium levels
c. Decreased levels of thyroid-stimulating hormone
d. Increased levels of thyroid-stimulating hormone
a. Increased serum calcium levels
The overall effect of parathyroid hormone (PTH)is to increase serum calcium and to decrease serum
phosphate concentration.
Which substance is a water-soluble protein hormone?
a. Thyroxine
b. Aldosterone
c. Follicle-stimulating hormone
d. Insulin
d. Insulin
Peptide or protein hormones, such as insulin, pituitary, hypothalamic, and parathyroid, are water
soluble and circulate in free (unbound) forms.
When insulin binds its receptors on muscle cells, an increase in glucose uptake by the muscle cells is the
result. This is an example of what type of effect by a hormone?
a. Pharmacologic
b. Permissive
c. Synergistic
d. Direct
d. Direct
Direct effects are the obvious changes in cell function that specifically result from the stimulation by a
particular hormone.
Thyroid-stimulating hormone (TSH) is released to stimulate thyroid hormone (TH) and is inhibited when
plasma levels of TH are adequate. This is an example of:
a. Positive feedback
b. Negative feedback
c. Neural regulation
d. Physiologic regulation
b. Negative feedback
Negative feedback occurs because the changing chemical, neural, or endocrine response to a stimulus
negates the initiating change that triggered the release of the hormone.

,The portion of the pituitary that secretes oxytocin is:
a. Posterior
b. Inferior
c. Anterior
d. Superior
a. Posterior
Only the posterior pituitary secretes oxytocin.
Antidiuretic hormone acts to cause vasoconstriction when:
a. Urine output is less than 20 ml/hr.
b. Serum osmolality is increased.
c. Osmotic and oncotic pressures are increased.
d. Vasopressin is pharmacologically administered.
d. Vasopressin is pharmacologically administered.
ADH was originally named vasopressin because, in extremely high doses, it causes vasoconstriction
and a resulting increase in arterial blood pressure. However, significant vasoconstriction may only be
achieved pharmacologically.
What is the target tissue for prolactin-releasing factor?
a. Hypothalamus
b. Anterior pituitary
c. Mammary glands
d. Posterior pituitary
b. Anterior pituitary
Prolactin-releasing factor targets the anterior pituitary gland to stimulate the secretion of prolactin.
Where is antidiuretic hormone (ADH) synthesized, and where does it act?
a. Hypothalamus; renal tubular cells
b. Renal tubules; renal collecting ducts
c. Anterior pituitary; posterior pituitary
d. Posterior pituitary; loop of Henle
a. Hypothalamus; renal tubular cells
Once synthesized in the hypothalamus, ADH acts on the vasopressin 2 (V2) receptors of the renal duct
cells to increase their permeability.

, Which mineral is needed for thyroid-stimulating hormone (TSH) to stimulate the secretion of thyroid
hormone (TH)?
a. Iron
b. Zinc
c. Iodide
d. Copper
c. Iodide
TSH, which is synthesized and stored in the anterior pituitary, stimulates secretion of TH by activating
intracellular processes, including the uptake of iodine necessary for the synthesis of TH.
Insulin transports which electrolyte in the cell?
a. Potassium
b. Calcium
c. Sodium
d. Phosphorus
a. Potassium
Insulin facilitates the intracellular transport of potassium, phosphate, and magnesium.
A person who has experienced physiologic stresses will have increased levels of which hormone?
a. Adrenocorticotropic hormone
b. Thyroid hormone
c. Somatostatin
d. Alpha endorphin
a. Adrenocorticotropic hormone
Stress has been shown to increase adrenocorticotropic hormone secretion.
Which hormone is involved in the regulation of serum calcium levels?
a. Parathyroid hormone (PTH)
b. Thyroxine (T4)
c. Adrenocorticotropic hormone (ACTH)
d. Triiodothyronine (T3)
a. Parathyroid hormone (PTH)
The parathyroid glands produce PTH, a regulator of serum calcium.
Which hormone inhibits the secretion of growth hormone (GH)?
