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
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 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
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.

Which of the following drugs is the most effective when it comes to
easing the symptoms of osteoarthritis?
A. Acyclovir
B. Baclofen
C. Acetaminophen
D. Diclofenac
Answer: D. Diclofenac
Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID) used to
treat generalized pain, rheumatoid arthritis, dysmenorrhea, and
osteoarthritis. It works by inhibiting the activity of COX-1 and COX-2,
which are responsible for the production of lipid compounds that are
essential in pain response and inflammation.
Acyclovir is an antiviral drug. Baclofen is a skeletal muscle relaxant drug.
Acetaminophen is an analgesic and antipyretic drug.
Which statement about the treatment of human immunodeficiency
virus (HIV) infection is true?
A. Treatment is difficult because antivirals are unsafe for the population
B. Asymptomatic individuals do not need to be treated
C. Treatment for HIV varies for each client
D. Only one drug is required to treat all clients with HIV
Answer: C. Treatment for HIV varies for each client

HIV is also known as the human immunodeficiency virus. Failure to
treat infection due to this virus can develop autoimmune deficiency
syndrome (AIDS) which is a life-threatening condition. Symptoms
include fever, swollen lymph nodes, fatigue, and weight loss. The
treatment for HIV is called antiretroviral (ARV) therapy. It involves the
use of a combination of antiviral drugs. The specifications of the drug
therapy for HIV are different for each individual because the treatment
is supposed to blend in with other medications that the client must
take, which depends on many factors such as comorbidities, nutrition,
and immune status.
The answer option A is incorrect because many antiviral drugs work
well. The answer option B is also wrong because even asymptomatic
clients with HIV require treatment. Treating HIV starting from the early
stages is better since it may help reduce the mortality rate. The answer
option D is also incorrect because the treatment usually involves a
combination of antiviral drugs
A client will be undergoing day surgery. The nurse told him to hold his
daily aspirin for three days before the surgery. What is the rationale for
this direction?
A. It has anti-inflammatory effects
B. It has antithrombotic effects
C. It has analgesic effects
D. It has antipyretic effects
