Answer: clindamycin

risk of an anaphylactic reaction has passed).
To minimize the chances of an anaphylactic reaction, penicillin should be administered
Correct Answer: an initial small dose is followed at 60-minute intervals
by
progressively larger doses until the full therapeutic dose has been achieved
Morphine overdose treatment
Correct Answer: -Naloxone (narcan)
-Intravenous, IM, and subQ. For initial treatment, administer IV
CT‐diarrhea‐action
Correct Answer: -decrease intestinal motility and thereby slow intestinal transit, which
allows more time for absorption of fluid and electrolytes
-activation of opioid receptors decreases secretion of fluid into the small intestine and
increases absorption of fluid and salt.
ACE inhibitor‐hyperkalemia
Correct Answer: -Inhibition of aldosterone release (secondary to inhibition of
angiotensin II production) can cause potassium retention by the kidney.
