NUR 641E MEDICAL CONCEPTS EXAM 2025 |136 QUESTIONS
WITH VERIFIED ACCURATE SOLUTIONS
1. 5HT3 Receptor Antagonist MOA:
block dopamine receptors in chemoreceptor trigger
zone (CTZ)
blocks serotonin receptors in CTZ, intestine walls, and
stomach
enhances GABA
blocks dopamine receptor and increases GI
motility blocks neurokinin-type receptors
in CTZ
activates cannabinoid receptors in CTZ
2. Imagine you are a healthcare professional who has
observed an adverse drug reaction in a patient. What steps
should you take to report this
reaction, and why is it crucial to do so?
Document the reaction in the patient's chart and inform
the FDA directly, as it is not necessary to report to your
institution.
Inform your supervisor and fill out a report for your
institution, which will then be submitted to the FDA to
ensure patient safety.
, Ignore the reaction if it seems mild, as only severe
reactions need to be reported to the FDA.
Report the reaction only if the patient experiences a
serious side effect, as minor reactions do not require
reporting.
3. What is the definition of horizontal transmission in the context
of infectious diseases?
Transmission of organisms from mother to child during
childbirth
Transmission of organisms from one person to another,
typically through direct contact
Transmission of organisms through contaminated food
or water
, Transmission of organisms via vectors like insects
4. Which symptoms occurring 2-4 hours after eating a meal
are typical of dumping syndrome in post gastrectomy
patients?
hypotension and
hypoglycemia headache
and shortness of breath
constipation and
hypertension
dysguesia and polydipsia
5. Explain the primary mechanism of action of proton pump
inhibitors (PPIs) in the treatment of gastric acid-related
disorders.
They neutralize stomach acid
They inhibit the proton pump in gastric parietal cells
They increase gastric
motility They block
histamine receptors
6. Explain how bulk laxatives like psyllium and
methylcellulose function in the treatment of constipation.
They stimulate the intestines to contract more frequently.
, They absorb water and increase the bulk of stool, making
it easier to pass.
They act as a lubricant to ease stool passage.
They inhibit the absorption of water in the intestines.
7. A patient with moderate persistent asthma is currently using a
short-acting bronchodilator. If their symptoms persist, what
would be the most
appropriate next step in their treatment plan?
Increase the frequency of the short-acting
bronchodilator
Introduce an inhaled low-dose corticosteroid and a
long-acting bronchodilator
