NCLEX LPN Pharmacological Parenteral Therapies 3 Exam Prep Questions
And Answers (202472025)
The LPN/LVN carries out the teaching plan for a post-myocardial infarction client. The LPN/LVN
explains the client is receiving digoxin (Lanoxin) because of which of the following?
1. Lanoxin dilates the coronary arteries.
2. Lanoxin regulates cardiac rhythm.
3. Lanoxin prevents premature ventricular contractions.
4. Lanoxin increases the rate of myocardial contractions. - ✔✔Strategy: Think about the action of
Lanoxin
(1) action of nitroglycerin
(2) CORRECT—cardiac glycoside, decreases conduction through the SA node and AV node
(3)action of lidocaine and procainamide (Pronestyl); decreases the response to ectopic pacemakers
(4) atropine increases heart rate; digoxin is prescribed for above normal cardiac rate
The nurse cares for a client receiving 1,200 mL of TPN solution daily. The IV set delivers 10 drops
per mL. The nurse should adjust the flow rate so that the client receives how many drops of fluid
per minute? Type the correct answer into the blank. Round to the nearest mL. - ✔✔Strategy:
total volume x drop factor/ total time in minutes
Correct answer: 8
The LPN/LVN identifies that which of the following medications is used for the treatment of
Parkinson's disease?
1. Phenobarbital (Luminal).
2. Carbidopa/Levodopa (Sinemet).
,3. Cimetidine (Tagamet).
4. Doxapram hydrochloride (Dopram). - ✔✔Strategy: Think about each answer.
(1.) anticonvulsant: decreases dysrhythmic brain activity
(2.) CORRECT—Sinemet is a dopamine agonist or a decarboxylase inhibitor; it prevents
peripheral destruction of levodopa; levodopa has an inhibiting affect on motor activity; in
Parkinson's the inhibitory effect is lost
(3.) anti-ulcer medication; has no effect on signs and symptoms of Parkinson's
(4.) stimulates respirations
A client is started on heparin therapy. The LPN/LVN knows that which of the following laboratory
tests is used to monitor the effectiveness of heparin?
1. Partial thromboplastin time.
2. Prothrombin time.
3. Bleeding time.
4. Protein electrophoresis. - ✔✔Strategy: Think about each answer.
(1)CORRECT—heparin inactivates prothrombin and prevents the formation of thromboplastin,
prolonging the clotting time; anticoagulation is effective when the PTT is 1.5 to 2 times the control
(2)used to measure therapeutic level of Coumadin; antidote is vitamin K
(3)measures duration of bleeding after standardized skin incision; prolonged in thrombocytopenic
purpura, platelet abnormality, leukemia, and severe liver disease
(4)differentiates between protein fractions
, Prednisone 2 mg PO q d is prescribed for a client with rheumatoid arthritis. What important points
should the LPN/LVN include when teaching the client about this drug?
1. The dosage will be adjusted until maximum effect is achieved.
2. The dosage should be increased and decreased gradually.
3. Some clients experience incontinence as a side effect of this drug.
4. Prednisone is a dangerous drug and must be carefully monitored. - ✔✔Strategy: Think about
the action of Prednisone.
(1.) true statement; however, will experience a reduction in joint pain but not necessarily achieve
complete relief of symptoms
(2.) CORRECT—it is important to withdraw this drug gradually to minimize the reaction of the
body to the sudden loss of exogenous steroids; with prolonged steroid administration, the adrenal
glands are suppressed
(3.) major side effects include risk of peptic ulcers, depression, fluid retention, and hypertension
(4.) has very serious long-term side effects which warrant monitoring; however, client needs to
recognize the importance of adhering to drug schedule
The LPN/LVN makes a home visit for a client scheduled for a subtotal thyroidectomy. The
LPN/LVN should intervene if which of the following is observed?
1. The client drinks Lugol's solution from a cup.
2. The client mixes Lugol's solution in fruit juice.
3. The client takes Lugol's solution after meals.
4. The client does not use iodized salt. - ✔✔Strategy: "Should intervene" indicates an incorrect
action.
(1) CORRECT—iodine solutions cause staining of the teeth and should be administered through
a straw
