EXAMINATION TEST QUESTIONS AND
SOLUTIONS FULLY VERIFIED
●● A 70-year-old male calls a clinic complaining of chest pain that
started after having sexual activity. He took sildenafil 50 mg about eight
hours ago. He has nitroglycerin 0.3 mg on hand.
How should the advanced practice registered nurse respond?
Answer: Do not take the nitroglycerin and call 911
Taking the medications together can cause a serious drop in blood
pressure leading to cardiovascular collapse.
●● A patient diagnosed with bipolar disorder who is in a mental health
clinic is discussing the possibility of beginning lithium with an advanced
practice registered nurse (APRN). The patient expresses understanding
and wishes to proceed with treatment. The APRN explains to the patient
that this medication requires specific lab monitoring and wants to draw
baseline labs. The patient asks why the test is needed.
Which explanation should the APRN provide to this patient?
Answer: A baseline blood urea nitrogen (BUN) and creatinine (CREA)
level needs to be drawn to assess kidney function prior to treatment.
,This drug can cause decreased renal function, and a baseline should be
drawn for future comparison.
●● An advanced practice registered nurse (APRN) is reviewing the
medications that will be commonly experienced with a new nurse to
determine whether the drugs are safe for the patients. The new nurse is
given a scenario where a patient is being prescribed sildenafil 25 mg po
prn, a prototype drug for erectile dysfunction.
Which patient may take this drug safely?
Answer: YES A 54-year-male with a medical history of hypertension,
mild eczema, and previous history of a urolithiasis where all is well

●● A patient is admitted with a diagnosis of Huntington disease. On
admission, the patient exhibits uncontrolled twitching, difficulty
,walking, trouble swallowing, confusion, and memory loss. The
advanced practice registered nurse (APRN) prescribes baclofen.
What is the mechanism of action of this medication?
Answer: NO Modulates the effects of glutamate at NMDA receptors
YES Inhibits neurotransmitter GABA
NO Halts the breakdown of acetylcholine by acetylcholinesterase
Alters the synthesis and release of norepinephrine, serotonin, and
dopamine
Incorrect. Cholinesterase inhibitors prevent the breakdown of
acetylcholine by acetylcholinesterase. They are used in patients with
Alzheimer's.
Correct! Huntington's disease involves a deficiency of the
neurotransmitters acetylcholine and y-aminobutyric acid in the basal
ganglia and extrapyramidal system.
●● A 21-year-old patient accompanied by a parent comes to a clinic for
an emergency visit with an advanced practice registered nurse (APRN)
following a seizure. Upon interviewing the patient and the parent, the
APRN determines that the seizure is classified by marked impairment of
consciousness and is followed by a period of central nervous system
(CNS) depression.
Which type of seizure is this patient experiencing?
Answer: Atonic
NO Myoclonic
YES Tonic-clonic
, Absence
Incorrect. Myoclonic seizures consist of a sudden muscle contraction
that lasts for just one second.
Correct! A tonic-clonic seizure is a type of seizure that is also called a
convulsion. This type of seizure can include muscle stiffness, loss of
consciousness, and body jerking.
●● A patient has been taking oral oxycodone every six hours for back
pain during the past three years. The patient suddenly decides to stop
