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

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.
Polydipsia refers to increased thirst caused by high blood sugar levels that make the blood more
concentrated.
Polyuria is the medical term for increased frequency of urination and passage of high volumes of
urine, followed by the excess intake of fluids.
Polyphagia refers to increased appetite which occurs because of excess loss of glucose in the
urine, making the body crave food.
A client breast cancer has been receiving radiation therapy. The nurse caring for her believes she
is at risk of developing skin changes due to her treatment. Which of the following instructions
must the nurse offer to the client considering this?
A) Clean the affected patch of the skin using a mild soap and lukewarm water
B) Put ice cubes on the affected area for two minutes to prevent itching
C) Wear clothes that offer compression during therapy sessions
D) Apply hydrocortisone cream to affected area to decrease the inflammation - CORRECT
ANSWER: Answer: A. Clean the affected patch of the skin using a mild soap and lukewarm
water
- Radiation therapy is a treatment that is often given to clients with cancer. While it has been
proven effective in targeting cancer cells in the body, it may also affect normal cells. Radiation
therapy can result in skin changes in clients receiving this kind of treatment. It may cause rashes,
itchy, scaly skin, and even blisters. An essential part of caring for the skin of a client receiving
radiation therapy is cleaning the affected area using a mild unscented soap and lukewarm water.
