The most common causes of left-sided heart failure include: - ANSWER-Acute
Myocardial Infarction
Feedback: The most common causes of left-sided heart failure are acute
myocardial
infarction and hypertension. Acute or chronic pulmonary disease can cause right
heart
failure, referred to as cor pulmonale. The causes of right-sided heart failure
include
stenosis or regurgitation of the tricuspid or pulmonic valves, right ventricular
infarction,
and cardiomyopathy. Manifestations (rather than causes) of heart failure reflect
the
physiologic effects of the impaired pumping ability of the heart, including
decreased
renal blood flow.
Assessment of an elderly female client reveals the presence of bilateral pitting
edema of the client's feet and ankles and pedal pulses that are difficult to
palpate. Auscultation of the client's lungs reveals clear air entry to bases, and the
client's oxygen saturation level is 93%, and vital signs are within reference
ranges.
What is this client's most likely health problem? - ANSWER-Right Sided Heart
Failure
Feedback: A major effect of right-sided heart failure is the development of
peripheral
edema. A client who is in shock would not have stable vital signs. Cor pulmonale
would
,be accompanied by manifestations of lung disease. Pericarditis is an
inflammation of the
pericardium exhibited by fever, precordial pain, dyspnea, and palpitations.
A client has been given the diagnosis of diffuse glomerulonephritis. They ask the
nurse practitioner what diffuse means. The nurse practitioner responds: -
ANSWER-All glomeruli and all parts of the glomeruli are involved
Feedback: Glomerular changes can be diffuse, involving all glomeruli and all
parts of the
glomeruli; focal, meaning only some of the glomeruli are affected; segmental,
involving
only a certain segment of each glomerulus; and mesangial, affecting only
mesangial cells.
Which of the following assessment findings would lead the nurse practitioner to
suspect the client has nephrotic syndrome? - ANSWER-Proteinuria and
generalized edema
Feedback: The nephrotic syndrome is characterized by massive proteinuria and
lipiduria,
along with an associated hypoalbuminemia, generalized edema, and
hyperlipidemia.
A client with a history of chronic pyelonephritis has been admitted several times
with recurrent bacterial infection of the urinary tract. The nurse practitioner
should anticipate educating this client with regard to which common treatment
regimen? - ANSWER-Continue taking antibiotics for full 10 to 14 days even if
symptoms disappear
Feedback: Chronic pyelonephritis involves a recurrent or persistent bacterial
infection
superimposed on urinary tract obstruction, urine reflux, or both. Chronic
obstructive
pyelonephritis can be bilateral, caused by conditions that obstruct bladder
outflow; or
unilateral, such as occurs with ureteral obstruction. Cranberry juice, forced
micturition,
and diuretics are not standard treatments for chronic pyelonephritis.
, The NP suspects that a client with kidney stones has developed magnesium
ammonium phosphate (struvite) stones based on which of the following
urinalysis results? Select all that apply - ANSWER-Alkaline urine pH
High Urine Phosphate Level
High bacterial count
Feedback: Magnesium ammonium phosphate stones, also called struvite stones,
form
only in alkaline urine and in the presence of bacteria that possess an enzyme
called
urease, which splits the urea in the urine into ammonia and carbon dioxide. The
ammonia
that is formed takes up a hydrogen ion to become an ammonium ion, increasing
the pH
of the urine so that it becomes more alkaline. Because phosphate levels are
increased in
alkaline urine and because magnesium always is present in the urine, struvite
stones form.
Uric acid stones develop in conditions of gout and high concentrations of uric
acid in the
urine. Cystine stones account for less than 1% of kidney stones overall but
represent a
significant proportion of childhood calculi. They are seen in cystinuria, which
results from
a genetic defect in renal transport of cystine
While explaining immunity to a client, the NP responds, "The body's internal
organs are protected from pathogens because - ANSWER-Our mucosal tissue
contains all the necessary cell components to fight a pathogen with an immune
response
Feedback: Secondary lymphoid tissues contain all the necessary cell
components (i.e., T
cells, B cells, macrophages, and dendritic cells) for an immune response.
Because of the
continuous stimulation of the lymphocytes in these tissues by microorganisms
constantly
