REx-PN Practice Exam Questions With Complete Solutions
A 11-year-old client in foster care is requested by his physician
to be one of the subjects for a drug trial. The nurse is unsure
whether the client should participate in the trial due to their age.
Which of the following information must the nurse consider in
this situation?
A. How well the 11-year-old client can understand the proposed
drug therapy
B. Policies regarding the involvement of minors in drug trials
C. Whether or not the client's foster parents can decide if the
client can take part in the trial
D. Whether the client is an emancipated minor who can decide
to take part in the trial Correct Answer Answer: B. Policies
regarding the involvement of minors in drug trials
Given the situation, the first and most reasonable thing that the
nurse must know are the policies regarding the involvement of
minors in drug trials. In general, parents or the legal guardians
must give their consent prior to involving their children in
clinical trials. However, in many states or provinces, minors in
foster care cannot be allowed to take part in trials.
A child falls out of a tree and is brought to the Emergency
Department by the parents. The nurse assesses the boy who is
crying and moaning in pain. The child has abrasions on their
arms and legs and a 2-cm laceration on their forehead. What is
the priority assessment given the nurse's findings?
A) The child's heart rate
B) Possible internal injuries
,C) Signs indicative of a head injury
D) Broken bones Correct Answer Answer: C) Signs indicative
of a head injury
- Considering the nature of the accident in which the client was
involved and since it appears that the client can still breathe on
his own ("the client was moaning and crying"), the nurse must
prioritize assessing them for any signs of possible head injury.
In children, symptoms that indicate that a client may have a
severe head injury include persistent crying, vomiting, and
refusal to eat. The nurse must also check for any bleeding or
other notable injuries in the client's head.
A child has been diagnosed with a urinary tract infection. Which
of the following instructions should the nurse give to the child's
parents?
A) Use an antibacterial soap when bathing the client
B) Rinse the child's clothes twice when doing the laundry
C) Give the child a loose-fitting underwear
D) Avoid the use of bubble baths and perfumes when bathing.
Correct Answer Answer: D. Avoid the use of bubble baths and
perfumes when bathing
- Chemicals found in bath salts, bubble baths, harsh soaps, and
bath bombs may irritate the sensitive patch of skin that
surrounds the urethra, which may increase a child's risk of
developing urinary tract infections; therefore, it is recommended
that only plain water be used when bathing.
,A child has been diagnosed with Type I diabetes mellitus. The
nurse is reading this child's endocrinologist prescription,
indicating the appropriate administration of insulin. Which of
the following insulin regimen is best for children with diabetes
mellitus?
A. The dose is dependent solely on age
B. Rapid-acting insulin must be injected intramuscularly two
times a day
C. The dose is administered in the vastus lateralis muscle
D. The dose is determined individually Correct Answer
Answer: D. The dose is determined individually
Currently, there is a recommendation for the individual
treatment of diabetes mellitus. Each client has a unique genetic
makeup, meaning different people are likely to respond
differently to the same drug regimen. For some, it may be
effective, while for others, it may not be as beneficial.
Although age does play a factor in insulin dosing, it is not the
sole factor—other factors include weight, blood glucose levels,
activity levels, lifestyle, diet, etc.
It is also common to mix different types of insulins to get the
best results. Short-acting insulin has a quick onset of action, a
duration of only a couple of hours, and can be administered
multiple times per day.
Long-acting insulin has a slower onset of action, a duration of
up to 24 hours, and is usually administered once daily. The
regime, including the type and frequency of insulin
administration, depends on the client's blood glucose levels.
, A child with a runny nose, cough, and low-grade fever is
suspected of having pertussis. Which of the following
interventions must the nurse do first?
A) Administer antibacterial drugs intravenously
B) Encourage the client to drink more fluids
C) Check the client's breathing rate and oxygen saturation
D) Employ droplet precautions Correct Answer Answer: D.
Employ droplet precautions
- Pertussis, also known as whooping cough, is a contagious
disease caused by Bordetella pertussis. It may be transmitted
through respiratory droplets made through coughing, talking, or
sneezing. Thus, if a client is suspected of having pertussis,
members of the healthcare team must practice the necessary
safety precautions for diseases transmitted in this manner.
A client arrives to the ER with a blood glucose of 32 mmol/L.
What are the 3 polys of Type diabetes mellitus?
A. Polyuria, polyopia, polycystic
B. Polydipsia, polyphagia, polyarthritis
C. Polyphagia, polyuria, polydipsia
D. Polyuria, polycythemia, polyarthritis Correct Answer
Polyphagia, polyuria, polydipsia
Type I diabetes mellitus (DM) develops when the body can no
longer produce insulin due to the destruction of beta cells of the
pancreas responsible for insulin production. Lack of insulin
production leads to poor control of blood glucose levels.
Polyphagia, polyuria, and polydipsia are known as the cardinal
signs of diabetes. They develop faster in clients with type I DM.
