1. A patient who requires a
higher dose to achieve the same therapeutic
effect is said to
(a) be cured. (b) be addicted
to the drug.
(c) have developed a tolerance
to the drug. (d) None of the above
Ans. C
2. A patient who is allergic
to shellfish is not likely to be allergic to some
medications.(a) True(b) False
Ans. B
3. What type of injection is
used to prevent medication from leaking back onto the tissue?
(a) IM(b) Z-Track(c) SC (d)
None of the above
Ans. B, When
a medication is injected directly into muscle, it is called an intramuscular
injection (IM). The Z-track method of IM is used to prevent tracking (leakage)
of the medication into the subcutaneous tissue (underneath the skin).
During the procedure, skin and tissue are pulled and
held firmly while a long needle is inserted into the muscle. After the
medication is injected, the skin and tissue are released. The needle track that
forms during this procedure takes the shape of the letter “Z,” which gives the
procedure its name. This zigzag track line is what prevents medication from
leaking from the muscle into surrounding tissue.
The procedure is usually administered by a nurse or
doctor. In some cases, you may be instructed in how to perform Z-track
injections on yourself at home.
Side effects can include swelling and injection
discomfort. Z-track injection is usually less painful than a traditional IM
injection.
4. Order: 1000 mL of IV fluid
q12h. Available: 1000 mL of IV fluid and
microdrip tubing. How many
gtts per minute will the nurse regulate the IV?
(a) 83 gtt/min (b) 83.3
gtt/min (c) 8.33 gtt/min (d) .833 gtt/min
Ans. A
5. Peppermint may relieve
migraine headaches when rubbed on the forehead.(a) True (b) False
Ans. B
6. Water-soluble vitamins are
excreted in urine shortly after they are absorbed. (a) True (b) False
Ans. A
7. Blenderized enteral
feedings are
(a) lactose-free liquid. (b)
powered mixed with milk.
(c) liquids that are
individually prepared based on the nutritional needs of the patient.
(d) powered mixed with water.
Ans. C, Hospital prepared blenderized
enteral tube feedings render unpredictable levels of micronutrients and
macronutrients and appear likely to deliver less than the desired amounts of
nutrients. Additionally, the viscosity of these feedings may be unsuitable for
infusion through feeding tubes.
8. When administering enteral
feedings, the patient may become dizzy if:
(a) large amounts of solution
is administered rapidly. (b) the solution is too concentrated. (c) the patient is supine (lying flat on
back). (d) none of the above.
Ans. A
9. Which of the following
medications prevents the formation of blood clots?
(a) Analgesic (b) Antipyretic (c)
Anticoagulant (d) All of the above
Ans. C, Anticoagulants
(antithrombics, fibrinolytic, and thrombolytics) are a class of drugs that work
to prevent the coagulation (clotting) of blood. Such substances occur naturally
in leeches and blood-sucking insects. A group of pharmaceuticals called
anticoagulants can be used in vivo as a medication for thrombotic
disorders.
nticoagulants
reduce blood clotting. This prevents deep vein thrombosis, pulmonary embolism, myocardial
infarction and ischemic stroke.
Coumarins (vitamin K antagonists)
These
oral anticoagulants are derived from coumarin, which is found in many plants. A prominent member of
this class is warfarin (Coumadin). It takes at least 48 to 72 hours
for the anticoagulant effect to develop. Where an immediate effect is required,
heparin must be given concomitantly. These anticoagulants are used to treat
patients with deep-vein thrombosis (DVT), pulmonary embolism (PE) and to
prevent emboli in patients with atrial fibrillation (AF), and mechanical prosthetic
heart valves.
10. A infant does not receive
a full dose of the drug given to its mother when the infant breastfeeds. (a)
True (b) False
Ans. A
