MSN 611 EXAM QUESTIONS WITH CORRECT
ANSWERS
Where |are |H4 |receptors |located? |- |CORRECT |ANSWER✔✔-predominantly |found |on |
eosinophils, |neutrophils, |and |T |cells.
In |the |stomach, |histamine |is |released |by: |- |CORRECT |ANSWER✔✔-enterochromaffin-like |(ECL) |
cells
Toxic |effect |of |first-generation |antihistamines |- |CORRECT |ANSWER✔✔-cardiac |arrhythmias
Anaphylaxis |and |Antihistamine |- |CORRECT |ANSWER✔✔-Steroids |may |be |added |as |adjunct |
therapy
Central |nervous |system |side |effect |of |antihistamines |that |elderly |patients |should |be |aware |of |-
|CORRECT |ANSWER✔✔-fatigue
Indication |of |H2 |antihistamines |used |- |CORRECT |ANSWER✔✔-used |to |inhibit |the |secretion |of |
gastric |acid |in |patients |with |gastrointestinal |(GI) |disorders
Which |of |the |following |is |a |second-generation |antihistamine |that |cannot |be |removed |by |
hemodialysis? |- |CORRECT |ANSWER✔✔-Cetirizine |(Zyrtec)
Initial |selection |of |antimicrobial |therapy |is: |- |CORRECT |ANSWER✔✔-Initial |selection |of |
antimicrobial |therapy |is |typically |empiric, |meaning |before |the |causative |pathogen |has |been |
identified
, Food-drug |or |drug-drug |interactions |with |antibacterial |medications |are |usually |addressed |by: |-
|CORRECT |ANSWER✔✔-This |interaction |is |usually |addressed |by |separating |the |administration |
times |or |avoiding |the |combination
Multiple |drug |combination |treatment |for |tuberculosis |- |CORRECT |ANSWER✔✔-It |has |
decreased |risk |of |resistance
Know |about |description |of |IFN-B |- |CORRECT |ANSWER✔✔-FN-β |products |have |antiviral |
properties |but |are |used |for |multiple |sclerosis, |not |infections
Side |effect |of |first-generation |antihistamines |related |to |their |anticholinergic |activity? |- |
CORRECT |ANSWER✔✔-dry |mouth, |dry |eyes, |urinary |retention, |constipation, |and |cognitive |
disturbances. |Anticholinergic |side |effects |can |be |further |exacerbated |by |other |anticholinergic |
medications, |such |as |tricyclic |antidepressants |(TCAs). |Because |monoamine |oxidase |inhibitors |
(MAOIs) |can |also |exacerbate |anticholinergic |side |effects, |first-generation |antihistamines |should
|not |be |used |during |treatment |or |within |2 |weeks |of |MAOI |discontinuation
How |is |enterobiasis |diagnosed? |- |CORRECT |ANSWER✔✔-Pinworm |can |be |diagnosed |by |
perianal |swab |using |adhesive |tape |that |is |examined |microscopically |for |eggs
Know |tuberculosis |treatment. |- |CORRECT |ANSWER✔✔-Directly |observed |therapy |(DOT) |is |a |
strategy |to |ensure |adherence |to |the |drug |regimen |and |is |an |especially |critical |element |to |
regimens |with |any |frequency |less |than |daily |dosing.
Because |these |agents |are |highly |susceptible |to |drug-drug |interactions, |any |exaggerated |side |
effects |or |inadequate |therapeutic |responses |when |using |isoniazid |and |rifamin |should |be |
considered |in |light |of |potential |drug |interactions |with |other |medications |the |patient |is |taking |
concurrently.
According |to |the |universal |prescribing |alerts |for |aminoglycosides, |extended |use |increases |risk |
for |infection |by |which |of |the |following |pathogens? |- |CORRECT |ANSWER✔✔-Can |cause |C. |
difficile-associated |diarrhea |and |pseudomembranous |colitis |with |extended |use
