CORRECT VERIFIED ANSWERS/ ALREADY GRADED
A+ (MOST RECENT!!)
Which assessment finding for an older adult patient does the nurse
ascribe to the natural aging process?
A. Tightening of the vocal cords
B. Decrease in residual volume
C. Decrease in the anteroposterior diameter
D. Decrease in respiratory muscle strength - Correct Answer – D.
As a person ages, vocal cords become slack, changing the quality and
strength of the voice; the anteroposterior diameter increases; respiratory
muscle strength decreases; and the residual volume increases.
The nurse knows that under normal physiologic conditions of tissue
perfusion, a patient will have what percent of oxygen dissociate from the
hemoglobin molecule?
A.25%
B.50%
C.75%
D.100% - Correct Answer – B.
Oxygen dissociates with the hemoglobin molecule based on the need for
oxygen to perfuse tissues. Under normal conditions, 50% of hemoglobin
molecules completely dissociate their oxygen molecules when blood
perfuses tissues that have an oxygen tension (concentration) of 26 mm
pg. 1
,Hg. This is considered a "normal" point at which 50% of hemoglobin
molecules are no longer saturated with oxygen.
Which assessment finding does the nurse interpret that is associated
most closely with lung disease?
A. Cough
B. Dyspnea
C. Chest pain
D. Sputum production - Correct Answer – A.
Cough is a main sign of lung disease. Dyspnea (difficulty in breathing or
breathlessness) is a subjective perception and varies among patients. A
patient's feeling of dyspnea may not be consistent with the severity of
the presenting problem. Sputum production may be associated with
coughing and indicate an acute or chronic lung condition. Chest pain can
occur with other health problems, as well as with lung problems.
A 58-year-old woman who has been diagnosed with throat cancer 1
week ago comes to the clinic today to discuss surgical options with her
health care provider. She is very tearful and appears sad when the nurse
calls her back to the examination room.
Based on her diagnosis, which clinical manifestation will the nurse
likely observe in the patient?
A. Hoarseness
B. Severe chest pain
C. Low hemoglobin level (anemia)
D. Numbness and tingling of the face - Correct Answer – A.
The patient may experience several different symptoms. The most
commonly seen with throat cancer is hoarseness, as well as mouth sores
pg. 2
,or a lump in the neck. Anemia can result if surgery is performed. Severe
pain in the chest can be associated with many different disorders and is
not usually linked to throat cancer. Numbness and tingling of the face
cannot be observed.
S/Sx of throat cancer: hoarsness, soar throat, difficulty swallowing,
mouth sores, ear pain, oral bleeding
The nurse is caring for a patient admitted to the ED after experiencing a
fall while rock climbing. The patient has several facial fractures. Which
objective assessment finding requires immediate intervention?
A. Malaligned nasal bridge
B. Blood draining from one of the nares
C. Crackling of the skin (crepitus) upon palpation
D. Clear glucose positive fluid draining from nares - Correct Answer –D.
Blood or clear fluid (cerebrospinal fluid, or CSF) may drain from one or
both nares. However, the presence of glucose in the clear drainage
indicates that CSF is draining, which could be caused by a skull fracture,
a serious complication CSF leak- yellow ring on testing strips. A
malaligned nasal bridge and crepitus may be observed when evaluating
general facial fractures and would be considered an expected finding.
The nurse is assessing a patient with a chest tube following a
pneumonectomy. Which assessment finding requires intervention?
A. Bandage around the posterior tube is loose.
B.2 cm of water is in the second chest tube chamber.
C. The water in the water seal chamber rises and falls with
inhalation/exhalation.
D. Bubbling present in the water seal chamber when the patient coughs.
- Correct Answer – A.
pg. 3
, After lung surgery, two tubes, anterior and posterior, are used. Dressings
around the wound should not be loose. The wounds should be covered
with airtight dressings.
A patient with a history of asthma is having shortness of breath. The
nurse discovers that the peak flowmeter indicates a peak expiratory flow
(PEF) reading that is in the red zone. What is the priority nursing action?
A. Administer the rescue drugs.
B. Take the patient's vital signs.
C. Notify the patient's prescriber.
D. Repeat the PEF reading to verify the results. - Correct Answer – A.
A PEF reading in the red zone indicates a range that is 50% below the
patient's personal best PEF reading and indicates serious respiratory
obstruction. The patient needs to receive rescue drugs immediately, and
then the prescriber should be notified. Repeating the PEF reading and
taking vital signs are also important, but doing so first delays the
administration of the rescue drugs.
The nurse understands that which of the following is the most common
symptom of pneumonia in the older adult patient?
A. Fever
B. Cough
C. Confusion
D. Weakness - Correct Answer – C.
The older adult with pneumonia often has weakness, fatigue, lethargy,
confusion, and poor appetite. Fever and cough may be absent, but
hypoxemia is usually present. The most common manifestation of
pneumonia in the older adult patient is confusion from hypoxia rather
than fever or cough.
