➢ While checking arterial blood gas results, a nurse finds respiratory acidosis. What does the nurse suspect is occurring
in the patient?
reduced tidal volumes
➢ A 20-year-old male is in acute pain. An arterial blood gas reveals decreased carbon dioxide (CO2) levels. Which
of the following does the nurse suspect is the most likely cause?
Hyperventilation
➢ The nurse is assessing a client with suspected respiratory acidosis. Which assessment items are priority for
the nurse to collect?
Rate and depth of respirations, Skin color and temperature, Appearance of the optic nerve
o The nurse is administering sodium bicarbonate to the client with respiratory acidosis. The nurse understands
that which is the primary goal of treatment for this client?
Removing excess acids in blood
➢ The student nurse is assisting in the care for a client with acute respiratory acidosis. The nurse explains to the
student nurse that the client's blood pH initially falls in the development of acute respiratory acidosis because
of which process?
Hypoventilation
2. ACTH
➢ The nurse is preparing a client for testing to determine if the client has Cushing syndrome. What tests are included
in the screening process
24-hour urine secretion of
cortisol Dexamethasone
suppression test Plasma levels of
ACTH
➢ A client comes to the clinic with fatigue and muscle weakness. The client also states she has been having diarrhea. The
nurse observes the skin of the client has a bronze tone and when asked, the client says she has not had any sun
exposure. The mucous membranes of the gums are bluish-black. When reviewing laboratory results from this client,
what does the nurse anticipate seeing?
Increased levels of ACTH
➢ A client is diagnosed with adrenocorticotropic hormone deficiency (ACTH) and is to begin replacement therapy.
Regarding which type of replacement will the nurse educate the client?
Cortisol replacement therapy

➢ Following destruction of the pituitary gland, ACTH stimulation stops. Without ACTH to stimulate the adrenal glands,
the adrenals' production of cortisol drops. This is an example of which type of endocrine disorder?
Secondary
➢ The nurse is preparing a client for a test that will measure negative feedback suppression of ACTH.
Which medication will the nurse administer in conjunction for this test?
Dexamethasone
➢ ACTH deficiency results in secondary hypercortisolism
➢ ACTH deficiency is most commonly caused by?
glucocorticoid withdrawal
➢ 6 symptoms of an ACTH deficiency
tiredness
weakness
anorexia
N/V
hypoglycemia
orthostatic hypotension
➢ interpretation of ACTH levels requires simultaneous assessment of plasma cortisol levels
➢ ACTH levels are normal to high in primary adrenal insufficiency
➢ ACTH levels are low to absent in secondary adrenal insufficiency
➢ The client has been taking an oral cortisol preparation for 2 years to manage an autoimmune disease. What effects
does the nurse expect this therapy to have on this client's circulating levels of ACTH and aldosterone?
Decreased ACTH, decreased aldosterone
➢ A nurse checks lab results as both Cushing syndrome and Addison disease can manifest with elevated levels of:
Adrenocorticotropic hormone (ACTH)
3. Acute epiglottitis
➢ A caregiver calls the pediatrician's office and reports to the nurse that her 4-year-old, who was fine the previous
day, complained of a sore throat early in the morning and now has a temperature of 102.6° F (39.2° C). The
caregiver has tried to get the child to nap but the child gets panicky, immediately sits back up, and leans forward
with her mouth

open and tongue out when the caregiver encourages her to lie down. The nurse suspects the child has which of the
following conditions?
Epiglottitis
➢ The caregivers of a child report that their child had a cold and complained of a sore throat. When interviewed
further they report that the child has a high fever, is very anxious, and is breathing by sitting up and leaning
forward with the mouth open and the tongue out. The nurse recognizes these symptoms as those seen with which
of the following disorders?
Epiglottitis
➢ The nurse is caring for a 5-year-old girl who shows signs and symptoms of epiglottitis. The nurse recognizes
a common complication of the disorder is for the child to:
be at risk for respiratory distress.
➢ A 5-year-old child is brought to the clinic by his father because the child developed a high fever over the past 2
to 3 hours. The nurse suspects epiglottitis based on which signs and symptoms?
• Difficulty speaking • Drooling • Sitting with neck extended • Frightened appearance
4. AIDS
➢ A 36-year-old man enters the hospital in an extremely debilitated condition. He has purple-brown skin lesions (a
symptom of Kaposi's sarcoma) and a persistent cough. A physical examination reveals swollen lymph nodes, and
laboratory tests find a very low lymphocyte count. Information taken during the personal history reveals that he
has multiple sex partners with whom he frequently engages in unprotected sex. What is likely to be the man's
problem and what is his prognosis?
He is probably suffering from AIDS. His outlook is poor once the disease has progressed to this
advanced stage. There is no cure, and drug therapy has had limited short-term success.
➢ Why does nursing care of a patient with acquired immune deficiency syndrome (AIDS) include monitoring of
T lymphocyte counts?
A decrease in the number of T cells would make the patient more susceptible to infection and unusual
cancers.
➢ What is the length of time from infection with the AIDS virus to seroconversion?
Up to six months
➢ A 21-year-old woman diagnosed with HIV/AIDS 4 years ago now presents with cytomegalovirus. The nurse explains
to the woman that the infection is caused by a common organism that normally does not cause infection in
someone with a healthy immune system. This type of infection is called what?
