therapy is:
alter the thyroid metabolic rate
relieve distress caused by increased thyroid size
destroy the overactive thyroid tissue

Radioactive iodine is used for thyroid ablation to destroy the
overactive thyroid tissue that causes the thyroid hormone
dysfunction.

accurate?
Black women are at higher risk for hip fractures than white women.

It is white women, not black women, who are at higher risk for hip

are not a normal consequence of aging.
Normal age-related changes of the skin may be confused with which of
the following clinical abnormalities?
dehydration
vitiligo
scabies
shingles - ANSWER- Correct Answer:
,dehydration
Normal age-related changes of the skin may be confused with
dehydration. Sebaceous gland activity tends to decrease with age,
and the skin's natural hydrators decline over the years. The skin's
ability to regenerate lipids compromising the protective lipid barrier
layer of the Stratum Corneum also declines with age, as does blood
flow to the skin, which may cause a drop in sebum production.
A 29-year old woman who is 6 weeks postpartum reports she is having
rectal bleeding that she believes is related to hemorrhoids. The Adult
Nurse Practitioner knows that this type of rectal bleeding is usually
described as:
dark brown to black blood color with normal-appearing stool
significant amounts of bright red blood
large blood clots and mucus mixed with stool
streaks of bright red blood on the stool - ANSWER- The Correct answer
is:
streaks of bright red blood on the stool
Choice D is the right answer. The color of blood related to
hemorrhoids is described as bright red, eliminating choice A.
Amount of blood with hemorrhoids is usually small or scant,
eliminating choices B and C. Internal hemorrhoids can occur during
or after childbirth. With chronically protruding or prolapsing
, hemorrhoids, the patient often reports mucous leaking and staining
of the undergarments. Other causes are obesity, constipation, and
prolonged sitting.
You have a patient with AIDS. You recognize that a low CD4 T-cell
count puts the patient at risk for opportunistic infections. You are
reviewing his lab reports and see that his CD4 T-cell count is indeed
low. Which of the following is the normal range for CD4 T-cell count?
800 -1400
700 -1400
400 - 1000
600 -1200 - ANSWER- Correct answer:
600 -1200
The normal CD4 T-cell count is 600 - 1200. A low CD4 T-cell count
is below 600. The destruction of the CD4 T-cell causes depletion in
the number of CD4 T-cells and consequently increases the risk of
infection. This puts the patient at risk for infection.
