NURS 505 ALL EXAMS QUESTIONS AND ANSWERS SOLVED CORRECTLY
Stress typically results in hypoglycemia. - Answers False
Stress typically leads to increased blood glucose levels due to the sympathetic nervous system control.
What is the most prevalent mineralocorticoid that regulates fluid balance? - Answers Aldosterone
The mineralocorticoids (aldosterone is the most prevalent naturally occurring mineralocorticoid) exert a
major influence on regulating potassium, sodium, and water balance.
Symptoms including severe tachycardia, fever, dehydration, heart failure, and coma are consistent with
which of the following? - Answers Thyroid storm
Thyroid storm is a crisis or life-threatening condition characterized by an exaggeration of the usual
physiologic response seen in hyperthyroidism. Whereas hyperthyroidism can cause symptoms such as
sweating, feeling hot, palpitations, and weight loss, the symptoms of thyroid storm are more severe,
resulting in complications such as fever, rapid heart rate, nausea/vomiting, diarrhea, irregular heart
beat, weakness, heart failure, confusion/disorientation, and coma.
A patient has been admitted to the unit with salt-losing adrenogenital syndrome. The patient is taking
fludrocortisone (Florinef) for replacement therapy in combination with a glucocorticoid. The nurse
would know that high-dose fludrocortisone requires the nurse to monitor for: - Answers an increase in
sodium and water retention along with potassium depletion.
Increased doses of fludrocortisone may result in excess retention of sodium and water along with
potassium depletion. Hypokalemia does not occur nor are sodium and water depleted or potassium
retained. This drug is usually given in combination with a glucocorticoid. Therefore, toxic effects would
not be expected.
A 31-year-old woman is being treated with fludrocortisone for Addison disease. In addition to
monitoring the client's urinary output, what other assessment should the nurse prioritize? - Answers
Blood pressure
Fludrocortisone acts on the distal renal tubule to enhance the reabsorption of sodium and to increase
the urinary excretion of both potassium and hydrogen ions. In small oral doses, the mineralocorticoid
effects of fludrocortisone predominate: urinary excretion of potassium, marked sodium retention, and a
, rise in blood pressure as a result of the physiologic effects of these electrolyte levels. The level of
consciousness is not affected by fludrocortisone unless there are significant changes in the fluid balance.
Which of the following hormones are secreted by the posterior pituitary gland? Select all that apply: -
Answers Vasopressin (ADH)
Oxytocin
Which of the following hormones are secreted by the anterior pituitary gland? Select all that apply: -
Answers GH
ACTH
TSH
Prolactin
Systemic antidiarrheals, such as loperamide (Imodium), decrease the number and liquidity of stools by
which of the following mechanisms? - Answers Decreasing intestinal motility
The nurse is caring for a patient who is going home on sucralfate (Carafate). The nurse would teach the
patient to take sucralfate: - Answers before meals.
Which of the following is the correct rationale for why the nurse would administer a laxative at a
separate time from the client's other medications? - Answers Laxatives may reduce absorption of other
drugs present in the GI tract.
A woman with numerous chronic health problems has been diagnosed with a benign gastric ulcer has
begun treatment with ranitidine (Zantac). Which of the following teaching points should the nurse
provide to this patient?
"This drug will help to eliminate the bacteria in your stomach that caused your ulcer."
"You should eat several small meals each day rather than three larger meals."
"Take each dose of ranitidine with an antacid of your choice."
"Quitting smoking will significantly increase the chance that this drug will heal your ulcer." - Answers
"Quitting smoking will significantly increase the chance that this drug will heal your ulcer."
Smoking reverses the drug-induced inhibition of nocturnal gastric acid production and hinders ulcer
healing.
A patient has been prescribed a histamine-2 (H2) receptor antagonist for the treatment of GERD. Why
are H2RAs more effective than H1 receptor antagonists in the treatment of diseases of the upper GI
tract? - Answers The parietal cells of the stomach have H2 receptors but not H1 receptors.
Stress typically results in hypoglycemia. - Answers False
