Which organism is a common opportunistic infection in a client
infected with human immunodeficiency virus (HIV)?
Oropharyngeal candidiasis
Cryptosporidiosis
Toxoplasmosis encephalitis
Pneumocystis jiroveci pneumonia
Rationale
Oropharyngeal candidiasis is the most common infection associated with HIV because
the immune system can no longer control Candida fungal growth. Pneumocystis jiroveci
pneumonia (PCP) is more common in a client infected with acquired
immunodeficiency syndrome (AIDS). It causes tachypnea and persistent dry cough.
Cryptosporidiosis, an intestinal infection caused by Cryptosporidium organisms,
presents in clients with AIDS as does toxoplasmosis encephalitis, which is caused by
Toxoplasma gondii and is acquired through contact with contaminated cat feces or by
ingesting infected undercooked meat.
Test-Taking Tip: You have at least a 25% chance of selecting the correct response in
multiple-choice items with four options. If you are uncertain about a question,
eliminate the choices that you believe are wrong and then call on your knowledge,
skills, and abilities to choose from the remaining responses.
A client has a prescription for 125 mg of phenytoin by mouth three
times a day. Phenytoin is supplied as an oral suspension of 25 mg/5 mL.
How many milliliters of solution will the nurse administer for each
dose? Record your answer as a whole number.
9 25 mL
Rationale
The correct amount of solution to administer at each dose is 25 mL. Solve the problem
with the use of ratio and proportion.
A client with schizophrenia who is receiving an antipsychotic medication
begins to exhibit a shuffling gait and tremors. The primary health care
provider prescribes the anticholinergic medication benztropine, 2 mg
daily. The nurse should inquire about which symptom when assessing
the client?
Constipation
Hypertension
Increased salivation
Excessive perspiration
Rationale
The anticholinergic activity of each medication is magnified, and adverse effects such
as paralytic ileus may occur. Hypotension, not hypertension, occurs with
anticholinergic medications. Dryness of the mouth, not increased salivation, occurs
with anticholinergic medications. Decreased, not increased, perspiration occurs with
anticholinergic medications.
Which test provides information on bladder capacity, bladder pressure,
and voiding reflexes?
Radiography
Renal arteriography
Electromyography (EMG)
Cystometrography (CMG)
Rationale
CMG is a urodynamic study that provides information on bladder capacity, bladder
pressure, and voiding reflexes. Radiography is a diagnostic test for clients with
disorders of kidney and urinary system to screen for the presence of two kidneys, to
measure kidney size, and to detect gross obstruction in kidneys or urinary tract. Renal
arteriography is a diagnostic study used to determine renal blood vessel size and
abnormalities. EMG is a urodynamic study used to test the strength of perineal
muscles in voiding.
According to the Centers for Disease Control and Prevention (CDC),
which stage of the human immunodeficiency virus (HIV) disease is
present in the client with a laboratory report revealing a CD4 + T-cell
count of 520 cells/mm 3?
Stage 1
Stage 2
Stage 3
Stage 4
Rationale
According to the CDC, HIV disease is divided into four stages. A client with a CD4 + T-
cell count of greater than 500 cells/mm 3 is in the first stage of HIV disease. A client
with a CD4 + T-cell count between 200 and 499 cells/mm 3 is in the second stage of
HIV disease. A client with a CD4 + T-cell count of less than 200 cells/mm 3 is in the
third stage of HIV disease. The fourth stage of HIV disease indicates a confirmed HIV
infection with no information regarding the CD4 + T-cell counts.
Which is the average height of a 4-year-old child?
2 feet, 10 inches (86.6 cm)
3 feet, 1.5 inches (95 cm)
3 feet, 4.5 inches (103 cm)
3 feet, 7.5 inches (110 cm)
