Which stressor triggers sickling? - ANSWER-Low temperature
causes vasoconstriction, slowing blood flow, leading to RBC
deoxygenation, which triggers sickling.
cause of ITP - ANSWER-In 70% of ITP cases, there is an
antecedent viral disease that stimulates production of
antiplatelet antibodies that bind to the plasma membranes of
platelets, causing platelet sequestration and destruction by
phagocytes in the spleen and other lymphoid tissues at a rate
that exceeds the ability of the bone marrow to produce them.
What is the likelihood that the patient will recover? with ITP -
ANSWER-The prognosis is excellent; 75% of children recover
completely within three months. By six months after onset, 80%
of affected children have regained normal platelet counts.
,An advanced practice registered nurse (APRN) is caring for an
older adult patient diagnosed with chronic obstructive
pulmonary disease (COPD). The APRN is concerned about the
patient's increased risk for community-acquired pneumonia
(CAP) and recommends the pneumococcal vaccination.
Which etiologic microorganism will this vaccine protect
against? - ANSWER-The pneumococcal vaccination protects
against Streptococcus pneumoniae, which is a community-
acquired pneumonia.
A patient presents to a hospital complaining of coughing,
dyspnea, fatigue, weight loss, chills, and fever. The patient has
been working as a painter for 25 years. An advanced practice
registered nurse (APRN) performs several diagnostic tests,
which reveal a diagnosis of hypersensitivity pneumonitis.
Which statement describes the mechanism of this condition? –
ANSWER-Hypersensitivity pneumonitis is an autoimmune
reaction initiated by alveolar macrophages and IgG antibody
production. Symptoms include cough, dyspnea, fatigue, weight
loss, chills, and fever.
A patient of child-bearing age reports not being recently
sexually active but is complaining of lactating without breast
pain or bleeding. A serum pregnancy test performed by an
advanced practice registered nurse (APRN) was negative.
,The patient is concerned about the possibility of breast cancer.
Which problem should the APRN suspect? - ANSWER-
Complaints of lactation with a negative blood pregnancy test is
generally due to galactorrhea. Galactorrhea often results from
having too much prolactin—the hormone responsible for milk
production after childbirth. It can be caused by some
medications, hypothyroid disease, chronic kidney disease,
opioid use, spinal cord injury, or even stress.
An advanced practice registered nurse (APRN) is caring for a
six-week-old infant admitted for difficulty breathing secondary
to excessive upper respiratory secretions.
Which mechanism of the pulmonary system affects the severity
of this problem? - ANSWER-Infants up to two or three months
of age are "obligatory nose breathers" and have difficulty
inhaling through their mouths. This is why nasal congestion is
a serious threat to young infants, especially during sleep.
A patient presents to an advanced practice registered nurse
(APRN) with complaints of vaginal discharge and pain upon
urination. Upon assessment, the APRN notes a fever of 101.4°F
and uterine tenderness. Laboratory results reveal an elevated
erythrocyte sedimentation rate.
What is the probable diagnosis? - ANSWER-Pelvic
inflammatory disease (PID) is an acute inflammatory process
, caused by infection and may involve any or all organs in the
upper genital tract, including the uterus, fallopian tubes, or
ovaries, and in its most severe form, the entire peritoneal
cavity. Patients may present with lower abdominal pain,
dysuria, dyspareunia, and irregular bleeding.
An adolescent patient reports to an advanced practice
registered nurse (APRN) with a five-day history of fever,
malaise, pharyngitis, generalized aches, swollen lymph nodes,
and an enlarged spleen. The lab results indicate a positive
monospot test.
Which infection should the APRN consider? - ANSWER-The
Epstein-Barr virus accounts for 85% of all cases of
mononucleosis and would be the reason for a positive
monospot test.
An advanced practice registered nurse (APRN) in a newborn
nursery is assessing an infant with Down syndrome for a
common congenital heart defect. Which condition should this
APRN be concerned about? - ANSWER-Ventricular septal
defect (VSD) is a common cardiac anomaly found in Down
syndrome. In a patient with VSD, blood can travel across the
hole from the left pumping chamber (left ventricle) to the right
pumping chamber (right ventricle) and out into the lung
arteries.
