When reviewing the medication orders for a client prescribed penicillin, the nurse
notes that the client is also prescribed warfarin. What possible effect may occur as
the result of an interaction between these drugs?
A. The penicillin will cause an enhanced anticoagulant effect of the warfarin.
B. The penicillin will cause the anticoagulant effect of the warfarin to decrease.
C. The warfarin will reduce the anti-infective action of the penicillin.
D. The warfarin will increase the effectiveness of the penicillin.
A
The nurse is teaching a client about their prescribed atorvastatin. What information
should the nurse include?
A. This medication can affect your blood's ability to clot so you will need routine
blood tests.
B. Grapefruit juice should be avoided as drinking grapefruit juice while taking this
medication can cause toxic levels of the drug.
C. Be sure to rise slowly from a lying or sitting position as this drug can cause low
blood pressure when changing positions.
D. Take your pulse before taking this medication to ensure it is at least 60 beats per
minute.
B
Atorvastatin is an antilipemic drug. Taking this drug with grapefruit juice
decreases the metabolism of atorvastatin which increases the risk for toxicity
(rhabdomyolysis)
The nurse is caring for a client with deep vein thrombosis (DVT). The nurse knows
which medications may be used to treat a DVT? Select all that apply.
1
,A. Digoxin
B. Heparin
C. Alteplase
D. Clopidogrel
E. Warfarin
F. Enoxaparin
G. Rivaroxaban
BEFG
The correct answers are anticoagulants that may be used for DVT. Digoxin is used
for heart failure. Alteplase is used for acute clot lysis in the case of an arterial clot
in MI or stroke. Clopidogrel is an antiplatelet agent used to prevent MI or stroke.
The nurse is evaluating coagulation labs for a client prescribed a continuous
intravenous heparin drip. Which lab value indicates heparin is having a therapeutic
effect?
A. Activated partial thromboplastin time 60 seconds
B. Prothrombin time 20 seconds
C. International normalized ratio 2.5
D. Platelet count 30,000
A
The aPTT is used for adjusting heparin therapy.
A day shift nurse is giving a hand-off report to an evening shift nurse. As the
nurses are reviewing the calculations for a client's intravenous heparin drip rate, the
nurses notice the pump was set incorrectly and the client has been getting double
the amount of heparin needed based on the protocol. What should the nurses do
first?
A. Call the primary care provider to report the error.
B. Collect a blood sample so lab can run an aPTT.
C. Assess the client for signs of bleeding.
D. Stop the heparin infusion.
D
The client has been getting too much heparin and is at high risk for a bleeding
event. The infusion should be stopped first, then assess the client for any signs of
2
,bleeding. Next call the provider. The provider will most likely order a STAT
aPTT.
The nurse is caring for a client prescribed amiodarone for the treatment of chronic
atrial fibrillation. The nurse plans for which goal?
A. Heart rate less than 110 beats per minute.
B. Blood pressure less than mmHg.
C. International normalized ratio 2.5.
D. Total cholesterol less than 200 mg/dL.
A
Amiodarone is an antidysrhythmic drug. The goal in atrial fibrillation is to keep the
HR less than 110 to avoid complications.
The nurse is caring for a client with a diagnosis of cerebral edema. Which
medication does the nurse anticipate administering?
A. Furosemide
B. Hydrochlorothiazide
C. Spironolactone
D. Mannitol
D
Mannitol is an osmotic diuretic and pulls fluid from the cells and interstitial spaces
into the blood stream. It also works as a diuretic to pull fluid into the renal tubule
for excretion.
The medical-surgical nurse is assessing aclient who has been prescribed
furosemide for several days. What assessment data is most concerning for the
nurse?
A. Potassium 2.3 mEq/L (ref. range 3.5-5 mEq/L)
B. Sodium 136 mEq/L (ref. range 135-145 mEq/L)
C. Blood pressure mmHg
D. Heart rate 102 beats per minute
A
Furosemide can further reduce potassium levels. Potassium supplementation is
needed or needs to be increased if already prescribed. Sodiumis on the low end of
3
, normal so should continue to be monitored but is not the priority. Blood pressure is
low and should be closely monitored. The potassium poses a higher risk currently.
The nurse is caring for a client who is currently receiving a 0.45% sodium chloride
infusion. What assessment finding suggests the client has received too much of this
fluid?
A. Jugular venous distention (JVD)
B. Blood pressure 93/50 mmHg
C. Capillary refill 2 seconds
D. Urine output 980 mL in 24 hour
B
A hypotonic fluid will cause water to leave the vascular space and move into the
cells. Hypotension may occur. JVD is present when the vascular space is
overloaded. The cap refill and urine output are normal.
When reviewing a client's medication list, the nurse knows that which medications
may be used to treat constipation? Select all that apply.
A. Loperamide
B. Polyethylene glycol
C. Docusate
D. Bisacodyl
E. Ondansetron
BCD
The nurse is caring for a client prescribed polyethylene glycol. What are adverse
effects of this medication? Select all that apply.
A. Loose stools
B. Dehydration
C. Constipation
D. Hypokalemia
E. Sedation
ABD
This drug is a laxative. Laxatives may cause loose stools, dehydration and
electrolyte imbalances. The medication should be held if these occur. Laxatives
treat constipation and do not cause it. Sedation does not occur.
