201.) A nurse is preparing to administer eardrops to an infant. The nurse plans to:
1. Pull up and back on the ear and direct the solution onto the eardrum.
2. Pull down and back on the ear and direct the solution onto the eardrum.
3. Pull down and back on the ear and direct the solution toward the wall of the canal.

4. Pull up and back on the ear lobe and direct the solution toward the wall of the canal. –
Correct Answer :3. Pull down and back on the ear and direct the solution toward the wall of
the canal.
Rationale:
When administering eardrops to an infant, the nurse pulls the ear down and straight back. In
the adult or a child older than 3 years, the ear is pulled up and back to straighten the auditory
canal. The medication is administered by aiming it at the wall of the canal rather than directly
onto the eardrum.
202.) A nurse is collecting data from a client about medications being taken, and the client
tells the nurse that he is taking herbal supplements for the treatment of varicose veins. The
nurse understands that the client is most likely taking which of the following?
1. Bilberry
2. Ginseng
3. Feverfew
4. Evening primrose –
Correct Answer :1. Bilberry
Rationale:
Bilberry is an herbal supplement that has been used to treat varicose veins. This supplement
has also been used to treat cataracts, retinopathy, diabetes mellitus, and peripheral vascular
disease. Ginseng has been used to improve memory performance and decrease blood
glucose levels in type 2 diabetes mellitus. Feverfew is used to prevent migraine headaches
and to treat rheumatoid arthritis. Evening primrose is used to treat eczema and skin irritation.

203.) A nurse is preparing to give the postcraniotomy client medication for incisional pain. The
family asks the nurse why the client is receiving codeine sulfate and not "something
stronger." In formulating a response, the nurse incorporates the understanding that codeine:
1. Is one of the strongest opioid analgesics available
2. Cannot lead to physical or psychological dependence
3. Does not cause gastrointestinal upset or constipation as do other opioids
4. Does not alter respirations or mask neurological signs as do other opioids –
Correct Answer :4. Does not alter respirations or mask neurological signs as do other opioids
Rationale:
Codeine sulfate is the opioid analgesic often used for clients after craniotomy. It is frequently
combined with a nonopioid analgesic such as acetaminophen for added effect. It does not
alter the respiratory rate or mask neurological signs as do other opioids. Side effects of
codeine include gastrointestinal upset and constipation. The medication can lead to physical
and psychological dependence with chronic use. It is not the strongest opioid analgesic
available.
204.) A client receives a dose of edrophonium (Enlon). The client shows improvement in
muscle strength for a period of time following the injection. The nurse interprets that this
finding is compatible with:
1. Multiple sclerosis
2. Myasthenia gravis
3. Muscular dystrophy
4. Amyotrophic lateral sclerosis –
Correct Answer :2. Myasthenia gravis
A+ TEST BANK 3
, OpenStax Pharmacology
Rationale:
Myasthenia gravis can often be diagnosed based on clinical signs and symptoms. The
diagnosis can be confirmed by injecting the client with a dose of edrophonium . This
medication inhibits the breakdown of an enzyme in the neuromuscular junction, so more
acetylcholine binds to receptors. If the muscle is strengthened for 3 to 5 minutes after this
injection, it confirms a diagnosis of myasthenia gravis. Another medication, neostigmine
(Prostigmin), also may be used because its effect lasts for 1 to 2 hours, providing a better
analysis. For either medication, atropine sulfate should be available as the antidote.
205.) A nurse is assisting in preparing to administer acetylcysteine (Mucomyst) to a client with
an overdose of acetaminophen (Tylenol). The nurse prepares to administer the medication
by:
1. Administering the medication subcutaneously in the deltoid muscle
2. Administering the medication by the intramuscular route in the gluteal muscle
3. Administering the medication by the intramuscular route, mixed in 10 mL of normal saline
4. Mixing the medication in a flavored ice drink and allowing the client to drink the medication
through a straw –
Correct Answer :4. Mixing the medication in a flavored ice drink and allowing the client to
drink the medication through a straw
Rationale:
Because acetylcysteine has a pervasive odor of rotten eggs, it must be disguised in a flavored
ice drink. It is consumed preferably through a straw to minimize contact with the mouth. It is
not administered by the intramuscular or subcutaneous route.
**Knowing that the medication is a solution that is also used for nebulization treatments will
assist you to select the option that indicates an oral route**
