WGU Pathophysiology Final Exam

Question 1 of 5

The neurotransmitter GABA mainly functions to trigger inhibitory postsynaptic potentials (IPSPs). Therefore, when explaining this to a group of nursing students, the nurse will state:

A. It takes at least three chemical substances (amino acids, neuropeptides, and monoamines) to stimulate any activity between the cells. B. There is a symbiotic relationship; therefore, the end result will be depolarization of the postsynaptic membrane. C. The combination of GABA with a receptor site is inhibitory since it causes the local nerve membrane to become hyperpolarized and less excitable. D. The neurotransmitters will interact with cholinergic receptors to bind to acetylcholine in order to produce hypopolarization within the cell.

Question 2 of 5

A patient is prescribed tadalafil (Cialis) for erectile dysfunction. What critical contraindication should the nurse discuss with the patient?

A. Use of nitrates B. Use of antihypertensive medications C. History of hypertension D. History of peptic ulcer disease

Question 3 of 5

A patient is prescribed medroxyprogesterone acetate (Provera) for the treatment of endometriosis. What should the nurse teach the patient about the use of this medication?

A. Medroxyprogesterone should be taken with food to prevent nausea. B. Medroxyprogesterone can be taken intermittently when symptoms worsen. C. Medroxyprogesterone should be taken at the same time each day to maintain consistent hormone levels. D. Medroxyprogesterone should be discontinued if side effects occur.

Question 4 of 5

A patient with an 18 pack per year history presents to a family practice clinic complaining of painless hoarseness and inability to clear mucus. A biopsy of respiratory tract cells is taken and shows that these cells have been replaced by less mature squamous epithelium cells. The nurse knows this type of change is referred to as:

A. Dysplasia B. Metaplasia C. Hyperplasia D. Coagulation

Question 5 of 5

A patient's current medical condition is suggestive of impaired erythropoiesis. Which of the following laboratory studies would be most clinically relevant in diagnosing this health problem?

A. White blood cell count with differential B. RBC, hemoglobin, and hematocrit C. INR and aPTT D. d-dimer and C-reactive protein
