You have at least a 25% chance of selecting the correct response in multiple-choice items. If
you are uncertain about a question, eliminate the choices that you believe are wrong and then call on your
knowledge, skills, and abilities to choose from the remaining responses.
Rationale
Simvastatin is a teratogen that is contraindicated in pregnancy because it is capable of causing fetal damage.
Simvastatin should be taken in the evening because most cholesterol is synthesized between midnight and
3:00 AM. Liver function tests should be done at 6 to 12 weeks initially and only then every 6 months. Although
wearing sunscreen should be taught, sensitivity reactions are a rare occurrence, and this is not as important.
Rationale
One of the most common side e ff ects of INH is peripheral neuritis due to vitamin B 6 deficiency, and vitamin
B 6 will counteract this problem. Weight gain is not a therapeutic e ff ect of this vitamin. Vitamin B 6 does not
a ff ect stomatitis and does not prevent night sweats.
Rationale
For myocardial infarction, morphine sulfate is the medication of choice because it relieves pain quickly and
reduces anxiety while decreasing cardiac workload. Although ketorolac and meperidine relieve pain, they do
not o ff er all the additional benefits of morphine. In addition, meperidine has additional adverse e ff ects.
Flurazepam is a hypnotic that may be used to reduce fear and restlessness; it is not e ff ective for the pain of a
myocardial infarction.
Test-Taking Tip: Start by reading each of the answer options carefully. Usually at least one of them will be
clearly wrong. Eliminate this one from consideration. Now you have reduced the number of response choices
by one and improved the odds. Continue to analyze the options. If you can eliminate one more choice in a
four-option question, you have reduced the odds to 50/50. While you are eliminating the wrong choices, recall
often occurs. One of the options may serve as a trigger that causes you to remember what a few seconds ago
had seemed completely forgotten.
Rationale
Insulin that is close to body temperature prevents vasoconstriction at the site and decreases irritation of
tissues. Insulin can be stored at room temperature for up to 1 month but must be kept away from heat or
sunlight. Inappropriate storage of insulin can decrease its stability and decrease, not increase, its therapeutic
action. Although it may be more convenient to keep insulin in the refrigerator, this is not a valid rationale;
temperature of the solution does not increase the viscosity of insulin. Neither adherence of insulin to the
syringe nor decreased resistance upon injection occurs.
Test-Taking Tip: Be aware that information from previously asked questions may help you respond to other
examination questions.
Rationale
Streptomycin sulfate is ototoxic and may cause damage to auditory and vestibular portions of the eighth
cranial nerve . Pyramidal tracts, cerebellar tissue, and peripheral motor end plates are not a ff ected by
streptomycin.
Test-Taking Tip: Bring to your test prep a positive attitude about yourself, your nursing knowledge, and your
test-taking abilities. A positive attitude is achieved through self-confidence gained by e ff ective study. This
means (a) answering questions (assessment), (b) organizing study time (planning), (c) reading and further
study (implementation), and (d) answering questions (evaluation).
