A nurse is caring for a patient who has myasthenia gravis. The prescriber has ordered
neostigmine (Prostigmin). An important initial nursing action before administration of the
medication includes assessing:
P 1
, • MED CERT 09/25/2026
a. the ability to raise the eyelids.
b. level of fatigue.
c. skeletal muscle strength.
d. swallowing ability. –
Correct Answer :ANS: D
Many patients hospitalized for myasthenia gravis do not have the muscle strength to swallow
well and need a parenteral form of the medication; therefore, assessing the patient's ability to
swallow is an important initial safety measure. Evaluating the patient's ability to raise the
eyelids, level of fatigue, and skeletal muscle strength are all important assessments both
before drug administration and during drug treatment, because they indicate the
effectiveness of the drug and help determine subsequent doses.
A nurse working in the emergency department is assigned to a child who is arriving by
ambulance after being involved in a spill of organophosphate insecticides. What will the nurse
expect to be the initial priority for treating this child?
a. Administering diphenhydramine to control secretions
b. Giving diazepam to control seizures
c. Providing mechanical ventilation and oxygen
d. Reporting the spill to the Environmental Protection Agency
- Correct Answer :ANS: C
All of these courses of action may be part of the treatment. However, the initial concern is to
prevent death from apnea caused by laryngospasm, bronchoconstriction, and paralysis
leading to apnea; therefore, maintaining an airway is the most important consideration.
Pralidoxime is the specific antidote and should be given next. Atropine is used to control

secretions. Diazepam is given when seizures occur. Reporting the accident to the proper
authorities is not a priority during a life-threatening emergency.
A patient who has myasthenia gravis will be taking neostigmine (Prostigmin). What will the
nurse emphasize when teaching this patient about the medication?
a. "Stop taking the drug if you have diarrhea."
b. "Take a supplementary dose before exercise."
c. "Use atropine if you have excessive salivation."
d. "Withhold the dose if ptosis occurs."
- Correct Answer :ANS: B
Neostigmine doses must be adjusted continually, and patients usually need supplemental
doses before exertion; therefore, patients must be taught how to modify doses as needed.
Increased gastrointestinal (GI) secretions can cause loose stools; this is a known adverse
effect that does not warrant stopping the drug. Atropine will help with excessive salivation
but should not be used routinely, because it can mask the early signs of anticholinesterase
overdose. Ptosis is one of the symptoms of myasthenia gravis and is an indication for taking
neostigmine.
Two nurses are discussing the major differences between physostigmine (Antilirium) and
neostigmine (Prostigmin). One nurse correctly makes which statement about physostigmine
(Antilirium)?
a. "It is not effective for treating poisoning by muscarinic blocking drugs."
b. "It can readily cross the blood-brain barrier."
c. "It does not cause any side effects."
P 3
, • MED CERT 09/25/2026
d. "It can be given by all routes."
- Correct Answer :ANS: B
The basic pharmacology of physostigmine is nearly identical to that of neostigmine, except
that physostigmine readily crosses membranes, including the blood-brain barrier; neostigmine
does not. Physostigmine and neostigmine are both effective for treating poisoning by
muscarinic blocking drugs. Neither physostigmine nor neostigmine is devoid of side effects.
Physostigmine can be given only intramuscularly (IM) or intravenously (IV); neostigmine is
given orally (PO), IM, IV, and subcutaneously (subQ).
A nurse is helping a nursing student who is administering a medication to a patient with
myasthenia gravis. Which statement by the student indicates the need for further teaching?
a."I will ask the patient to sip some water before giving the medication."
b."I will let the patient sleep after giving the medication, because rest is important."
c."I will record muscle strength assessments before and after I give the medication."
d."I will report excessive salivation to the patient's prescriber."
- Correct Answer :ANS: B
An important assessment indicating the medication's effectiveness is evaluating a patient's
ability to raise the eyelids. Letting the patient sleep, even though rest is important, would
prevent the nurse from making this assessment. To make sure the patient can safely swallow
a pill, the nurse must evaluate swallowing ability by asking the patient to take a sip of water.
Muscle strength assessments before and after medication administration help the nurse
evaluate the medication's effectiveness. Excessive salivation may be a sign of drug toxicity
and should be reported.
