NUR 504 Exam 4 Q&A Bank 2026 | Exam Success Guide |
Graded A+
1. Describe the role of the olfactory receptors and their significance in the
respiratory system.
Olfactory receptors filter air before it enters the lungs.
Olfactory receptors regulate blood flow in the nasal passages.
Olfactory receptors are responsible for detecting odors, which is
essential for the sense of smell and can influence respiratory
functions.
Olfactory receptors are involved in the production of mucus in the
nasal cavity.
2. True or False? The nasal cavity is lined with cilia.
true
false
3. The nurse is doing an physical assessment of a client and knows that the
following two sinuses are the only sinuses that are able to be palpated.
Ethmoid and maxillary sinuses
Frontal and sphenoid sinuses
Frontal and maxillary sinuses
Ethmoid and sphenoid sinuses
4. What is a common symptom associated with deep vein thrombosis?
Shortness of breath
Coughing up blood
, Chest pain
Swelling
5. What are the four characteristics used to describe breath sounds?
Intensity, pitch, duration, and quality
Frequency, amplitude, duration, and clarity
Volume, tone, length, and resonance
Strength, pitch, duration, and clarity
6. If a patient presents with a very sore throat that interferes with swallowing,
what should be the immediate nursing intervention?
Assess the patient's ability to swallow and provide appropriate pain
relief.
Encourage the patient to eat solid foods immediately.
Only provide water to the patient.
Ignore the sore throat if the patient has no fever.
7. If a pediatric patient has not developed their first tooth by 12 months, what
might a physician consider in their assessment?
Increased risk of dental cavities
Potential developmental delays
Normal variation in tooth eruption
Need for immediate dental intervention
8. Describe the role of the epicardium in the structure of the heart.
, The epicardium is responsible for pumping blood throughout the
body.
The epicardium is the layer that contains the heart's blood vessels.
The epicardium is involved in the conduction of electrical impulses in
the heart.
The epicardium serves as the thin, protective outer layer of the
heart, providing a barrier and contributing to the heart's overall
structure.
9. Interpret the implications of a very sore throat on a patient's ability to eat and
drink.
A very sore throat has no effect on swallowing.
A very sore throat may cause difficulty in swallowing, impacting the
patient's ability to eat and drink.
A very sore throat only affects the ability to speak.
A very sore throat is usually not serious.
10. Which sinuses are located in the cheek area and can be examined directly
by a physician?
Ethmoidal
Sphenoidal
Frontal
Maxillary
11. "The most definitive but most invasive test in the diagnosis of heart disease;
involves passing a smaller catheter into the heart and injecting contrast
medium"
, Electrophysiologic study
Cardiac catheterization
Echocardiogram
Electrocardiography
12. In a clinical setting, how might the differences in breath sounds between
pediatric and adult patients influence a nurse's assessment?
Nurses can assume all patients have similar respiratory characteristics
regardless of age.
Nurses must consider the developmental stage of the respiratory
system when assessing breath sounds in pediatric patients.
Nurses should only focus on the volume of breath sounds, ignoring
pitch.
Nurses should assess breath sounds in pediatric patients the same
way as in adults.
13. Describe the Cheyne-Stokes breathing pattern and explain why it may be
considered normal in children during sleep.
Cheyne-Stokes breathing is a pattern of deep, labored breaths that
occurs during exercise.
Cheyne-Stokes breathing involves a cyclical pattern of increasing
and decreasing respiratory effort, which can be normal in children
during sleep due to their developing respiratory control.
Cheyne-Stokes breathing is a consistent, steady breathing pattern
that indicates respiratory distress.
Cheyne-Stokes breathing is characterized by rapid, shallow breaths
and is always abnormal in children.
