Question 1 See full question
A client is scheduled to have a graded exercise test. The nurse explains to the client
that the test will determine how:
You Selected:
well the body reacts to controlled exercise stress.
Correct response:
well the body reacts to controlled exercise stress.
Explanation:
Graded exercise testing is a diagnostic and prognostic tool used to determine the
physiologic responses to controlled exercise stress. Information gained from a
graded exercise test can achieve diagnostic, functional, and therapeutic objectives
for the client. Graded exercise tests involve the use of a treadmill, stationary
bicycle, or arm ergometry. The information obtained from this test is not used to
set the incline on the treadmill, and measuring the distance walked and the
duration of the walk are not the purpose of a graded exercise test.
Remediation:
Electrocardiography, exercise
Question 2 See full question
A nurse should include which discharge instruction for clients receiving tricyclic
antidepressants?
You Selected:
Restrict fluid and sodium intake while using this medication.
Correct response:
Don't consume alcohol while using this medication.
Explanation:
Drinking alcohol can potentiate the sedating action of tricyclic antidepressants. Dry
mouth and blurred vision are normal adverse effects of tricyclic antidepressants.
Fluid and sodium intake must be monitored during lithium treatment, not during
,treatment with tricyclic antidepressants. Safe use of tricyclic antidepressants during
pregnancy and breast-feeding hasn't been established.
Remediation:
Amitriptyline hydrochloride
Clomipramine hydrochloride
Question 3 See full question
The nurse prepares to administer promethazine 35 mg IM as prescribed PRN for a
client with cholecystitis who has nausea. The ampule label reads that the
medication is available in 25 mg/mL. How many milliliters should the nurse
administer? Record your answer using one decimal place.
Your Response:
0.7
Correct response:
1.4
Explanation:
The following formula is used to calculate the correct dosage:
35 mg/X = 25 mg/1 mL
X = (35/25) mL
X = 1.4 mL.
Question 4 See full question
Levothyroxine 0.2 mg orally has been prescribed for a client diagnosed with
hypothyroidism. The nurse has available 0.05-mg tablets. How many tablets should
the nurse prepare to give the client?
You Selected:
two tablets
Correct response:
four tablets
,Explanation:
0.2 mg/x tablet = 0.05 mg/1 tablet.
x = 4 tablets.
Remediation:
Levothyroxine sodium
Question 5 See full question
What is the nurse’s priority intervention for a toddler who has just had a hip-spica
cast applied?
You Selected:
Assess sensation, circulation, and motion of the child’s feet and toes
Correct response:
Assess sensation, circulation, and motion of the child’s feet and toes
Explanation:
Assessing sensation, circulation, and motion is necessary in all children with a cast.
Fluids should be encouraged, and careful diapering and padding will keep the
child’s cast dry. Discharge instructions are not a priority, but should be shared at a
later time. Children experiencing pain should receive medication as needed.
Remediation:
Cast assessment and management, pediatric
Casting, pediatric
Question 6 See full question
A child requires IV fluids to infuse at 27 ml/hr. The tubing delivers 60 gtts/ml. How
many gtts/min should the nurse count to ensure that the fluid is safely infusing?
You Selected:
27 gtts/min
Correct response:
, 27 gtts/min
Explanation:
The nurse should count 27 gtts/min. 27 ml/h x 60 gtts/ml ÷ 60 min/h = 27 gtts/min
Remediation:
IV infusion, dose and flow rate calculations
Question 7 See full question
Before placement of a ventriculoperitoneal shunt for hydrocephalus, an infant is
irritable, lethargic, and difficult to feed. To maintain the infant's nutritional status,
which action would be most appropriate?
You Selected:
Give the infant small, frequent feedings.
Correct response:
Give the infant small, frequent feedings.
Explanation:
An infant with hydrocephalus is difficult to feed because of poor sucking, lethargy,
and vomiting, which are associated with increased intracranial pressure. Small,
frequent feedings given at times when the infant is relaxed and calm are tolerated
best. Feeding an infant before any procedure is inappropriate because the stress of
the procedure may lead to vomiting. Ideally, the infant should be held in a slightly
vertical position when feeding to prevent backflow of formula into the eustachian
tubes and subsequent development of ear infections. Giving large, less frequently
feedings allows for rest, but typically results in more vomiting.
Remediation:
Ventriculoperitoneal shunt placement
Hydrocephalus, pediartic
