Question 1 of 5
A nurse is preparing to administer clindamycin palmitate 225 mg PO every 8 hr to a client. The amount available is clindamycin palmitate oral suspension 75 m/5mL. How many ml- should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale: Volume (mL) = Ordered dose (mg)/Concentration (mg/mL) = 225/(75/5) = 15 mL.
Question 2 of 5
An adrenergic agonist is ordered for a client in cardiogenic shock. The nurse will note that this drug has had its primary intended effect if which expected outcome occurs?
Correct Answer: A
Rationale: An agonist means it binds to mimic the action of the endogenous neurotransmitter. Adrenergic receptors act to stimulate the sympathetic nervous system leading to the fight/flight response. Increase in heart rate leads to increased cardiac output.
Question 3 of 5

Question 4 of 5
A client tells the nurse that he is having nausea and decreased appetite during drug therapy with a tetracycline antibiotic. Which statement is the nurse's best advice to the client?

Rationale: Water helps dilute and flush the drug down. Milk, yogurt, and antacids affect absorption of tetracycline.
Question 5 of 5
A client is receiving high doses of methotrexate and is experiencing severe bone marrow suppression. The nurse expects which intervention to be ordered with this drug to reduce this problem?
Correct Answer: B
