NU129 Practice Questions With
Solution
You are the nurse caring for Mr. Toma, a 36-year-old man who is having
muscle spasms in his back after falling from a ladder while working on his
roof at home. The physician has prescribed cyclobenzaprine to help relieve
the muscle spasms in his back. For which medical condition would you want
to hold the medications because of the increased risk of adverse effects? -
ANSWER A history of supraventricular tachycardia
Explanation:
Cyclobenzaprine is contraindicated for patients with hyperthyroidism
because of a possible increased risk of arrhythmias or an exacerbation of
tachycardia. Because of its similarity to the TCAs, cyclobenzaprine is also
contraindicated for use within 14 days of administration of monoamine
oxidase inhibitors (MAOIs). In overdoses, TCAs cause conduction
disturbances and have been associated with torsades de pointes (an atypical
tachycardia) and death. Because it is closely related to the TCA amitriptyline,
cyclobenzaprine should be used cautiously in patients with heart failure,
cardiac arrhythmias, or atrioventricular block or other conduction
disturbances and in those who are in the acute recovery phase following
myocardial infarction (MI)
Question 2:
(see full question) A 43-year-old woman was diagnosed with multiple
sclerosis 2 years ago and has experienced a recent exacerbation of her
,symptoms, including muscle spasticity. Consequently, she has been
prescribed Dantrolene (Dantrium). In light of this new addition to her drug
regimen, what teaching point should the woman's nurse provide? - ANSWER
"You might find that this drug exacerbates some of your muscle weakness
while it relieves your spasticity."
Correct
Explanation:
Dantrolene causes weakness because of its generalized reduction of muscle
contraction. It is not associated with drug dependence, hyperglycemia,
hypoglycemia, or hallucinations
(see full question) The nurse can determine that the client taking uric acid
inhibitors is drinking enough fluids when which of the following occurs? -
ANSWER The daily urine output is about two liters.
Explanation:
When taking uric acid inhibitors, the client should drink about 3000 mL per
day, and the daily urine output should be about two liters. The client's weekly
weight and lip condition are not the best assessments to evaluate adequate
fluid intake (prevention of urate stone formation); they are acceptable
methods to assess for dehydration.
(see full question) Which of the following would the nurse include as possible
adverse effects when teaching a patient about phenytoin? - ANSWER
Dantrolene (Dantrium)
Explanation:
Dantrolene (Dantrium) acts directly on skeletal muscle to inhibit muscle
, contraction. It is used to relieve spasticity in neurologic disorders (eg, MS,
spinal cord injury) and to prevent or treat malignant hyperthermia, a rare but
life-threatening complication of anesthesia characterized by hypercarbia,
metabolic acidosis, skeletal muscle rigidity, fever, and cyanosis.
Question 6:
(see full question) Which of the following adverse effects could be the most
significant for a patient taking tizanidine (Zanaflex)? - ANSWER Hypotension
Correct
Explanation:
Tizanidine has been associated with hypotension, which could be a safety risk
especially if the patient is also taking an antihypertensive drug. Constipation,
dry mouth, and fatigue are common adverse effects, which do not pose a
safety risk.
A patient, newly diagnosed with a seizure disorder, asks the nurse why they
are receiving a specific drug. What would be the best answer by the nurse? -
ANSWER When prescribing an AED, the physician takes into account the type
of seizure the patient is having
Correct
Explanation:
Type of seizure is a major factor in drug selection. Age and gender are not
factors that impact the choice of AED. Options A and B are incorrect
An operating room nurse is assisting the anesthesiologist in the preparation
of an intravenous dose of dantrolene. What emergent issue most likely
