You are collecting an oral temperature from your patient. The patient complies with your instructions and you correct which of the following patient actions in order to obtain an accurate finding?
The patient keeps their mouth slightly opened.
The thermometer is placed in the posterior sublingual pocket of the mouth.
The thermometer is placed under the patient's tongue.
The patient takes care to not bite on the thermometer probe.
Show the answer and explanation
Answer: A. The patient keeps their mouth slightly opened.
Topic: Oral Temperature Measurement
Oral temperature accuracy requires the thermometer to sit under the tongue with the mouth closed; an open mouth allows ambient air to cool the probe, yielding a falsely low reading. Therefore you correct the patient’s slightly opened mouth.
Why the others are wrong
B – Posterior sublingual placement is correct; no correction needed.
C – Under‑tongue placement is proper for oral readings.
D – Avoiding biting protects the probe but isn’t an error to correct.
Remember: Closed mouth = accurate oral temp; open mouth cools probe.
Injury to which of the following nerves might impair a patient's sense of smell?
Oculomotor
Optic
Olfactory
Trigeminal
Show the answer and explanation
Answer: C. Olfactory
Topic: Cranial Nerve Function
The olfactory nerve (cranial nerve I) is solely responsible for transmitting sensory information about odors to the brain. Injury to this nerve directly impairs or destroys the patient's sense of smell, a condition known as anosmia.
Why the others are wrong
A – Controls eye movement and pupil constriction, not smell.
B – Transmits visual information from the retina, not smell.
D – Responsible for facial sensation and chewing, not smell.
Remember: Olfactory detects odors; CN I is for smell.
A patient has a urinary catheter placed for urine collection during an operative procedure. Following conclusion of the procedure, the urinary catheter:
May be left in as long as needed
Should be discontinued as soon as the patient is able to ambulate
Should be removed as soon as possible
May be left in up to 48 hours following the procedure
Show the answer and explanation
Answer: C. Should be removed as soon as possible
Topic: Postoperative Catheter Care
To minimize the risk of catheter-associated urinary tract infections (CAUTIs), indwelling urinary catheters must be removed as soon as possible postoperatively once they are no longer clinically indicated, rather than waiting for arbitrary timeframes or milestones.
Why the others are wrong
A – Prolonged catheterization without strict medical necessity significantly increases the risk of acquiring a CAUTI.
B – Waiting for ambulation unnecessarily delays removal, increasing the risk of urinary tract infections.
D – Routine 48-hour retention is outdated; catheters must be removed immediately when no longer indicated.
Remember: To prevent CAUTI, get the catheter out ASAP!
The nurse is investigating a patient's chief complaint. The nurse remembers that the use of the PQRSTU mneumonic can be helpful for asking questions in an orderly fashion. The nurse identifies that the "U" part of the mneumonic reflects:
Unconsciousness
Uncertainty
Understanding
Urgency
Show the answer and explanation
Answer: C. Understanding
Topic: PQRSTU Pain Assessment Mnemonic
In the PQRSTU pain assessment mnemonic, the "U" stands for "Understanding" or "Understand patient's perception." This component explores the patient's own perspective, beliefs, and concerns regarding what is causing their pain or symptom.
Why the others are wrong
A – Unconsciousness is a state of arousal, not a component of this subjective assessment tool.
B – Uncertainty is not a component of this standard subjective symptom assessment framework.
D – Urgency is not part of the PQRSTU mnemonic; timing (T) addresses onset and duration.
Remember: "U" is for "Understanding" the patient's own perspective of their pain.
An individual who experiences injury to their vestibulocochlear nerve may have difficulty with: ______________________ and ____________________________.
Memory and hearing
Vision and hearing
Memory and balance
Hearing and balance
Show the answer and explanation
Answer: D. Hearing and balance
Topic: Vestibulocochlear Nerve Function
The vestibulocochlear nerve (cranial nerve VIII) consists of two main branches: the vestibular branch, which regulates balance and spatial orientation, and the cochlear branch, which transmits sound. Injury to this nerve impairs both hearing and equilibrium.
Why the others are wrong
A – Memory is a cerebral function, not regulated by cranial nerve VIII.
B – Vision is controlled by the optic nerve, not the vestibulocochlear nerve.
C – Memory is controlled by the cerebrum, not the vestibulocochlear nerve.
Remember: Vestibulocochlear: 'Vest' keeps you balanced, 'cochlear' helps you hear.
facial drooping, arm weakness, and abnormal speech.
visual changes, arm weakness, and abnormal speech
Show the answer and explanation
Answer: C. facial drooping, arm weakness, and abnormal speech.
Topic: Acute Stroke Symptoms
The most common acute stroke symptoms are represented by the FAST acronym: facial drooping, arm weakness, and abnormal or slurred speech. Recognizing these classic signs immediately is crucial for timely emergency intervention and reperfusion therapy.
Why the others are wrong
A – Impaired auditory sensation is an uncommon presentation for an acute stroke.
B – Memory deficits are not among the most common acute stroke symptoms used for rapid screening.
D – Visual changes can occur, but facial drooping is a more common and classic screening symptom.
Remember: Think FAST for stroke: Face, Arm, Speech, Time.
The nurse is conducting a primary survey and notes the patient's height and weight. According to the documentation in the patient chart, the patient has a recorded Body Mass Index of 31 kg/m 2 . The nurse understands that this places the patient in which of the following categories?
Obese
Healthy Weight
Underweight
Overweight
Show the answer and explanation
Answer: A. Obese
Topic: Body Mass Index Classification
According to CDC BMI categories, a value of 31 kg/m2 exceeds the 30 kg/m2 threshold that defines obesity, placing the patient in the obese classification rather than overweight or normal weight.
Why the others are wrong
B – Healthy weight spans 18.5–24.9, which does not include 31.
C – Underweight requires BMI below 18.5, far lower than 31.
D – Overweight ends at 29.9; 31 exceeds that range.
When testing pupillary response to light, the nurse expects which of the following to reflect normal pupillary response.
In the patient's dominent eye, the pupil constricts more quickly.
In the patient's dominent eye, the pupil constricts more slowly.
Both pupils should react in the same manner to the light.
Show the answer and explanation
Answer: C. Both pupils should react in the same manner to the light.
Topic: Pupillary Light Reflex
A normal pupillary response is consensual, meaning shining a light into one eye causes both pupils to constrict equally and simultaneously. Eye dominance does not affect the speed or degree of pupillary constriction.
Why the others are wrong
A – Eye dominance does not affect pupillary constriction speed or size.
B – Eye dominance does not influence the speed of the pupillary reflex.
Remember: Consensual response: both pupils constrict together, regardless of eye dominance.
The technique of pursed lip breathing is valuable for patients with COPD because it:
Provides a distraction from feelings of dyspnea
Lengthens the process of inhalation
Shortens the process of exhalation
Lengthens the process of exhalation
Show the answer and explanation
Answer: D. Lengthens the process of exhalation
Topic: COPD Breathing Techniques
Pursed‑lip breathing creates back pressure, slowing and lengthening expiration, preventing airway collapse and improving gas exchange in COPD patients. It also reduces respiratory rate and dyspnea, enhancing oxygenation.
Why the others are wrong
A – Distraction may help anxiety but is not the primary physiologic effect.
B – Inhalation is not prolonged; the technique focuses on exhalation.
C – Exhalation is lengthened, not shortened; shortening would worsen air trapping.
The _______________________ is responsible for higher level brain functions such as memory, emotion, and consciousness.
Brain stem
Spinal Cord
Cerebrum
Cerebellum
Show the answer and explanation
Answer: C. Cerebrum
Topic: Brain Structure and Function
The cerebrum is the largest part of the brain and is responsible for complex, higher-level functions including conscious thought, memory, reasoning, and emotion. It is divided into two hemispheres and contains the cerebral cortex.
Why the others are wrong
A – The brain stem regulates autonomic, life-sustaining functions such as breathing, heart rate, and blood pressure.
B – The spinal cord transmits sensory and motor signals between the brain and the body.
D – The cerebellum primarily coordinates voluntary movements, balance, posture, and motor learning.
Remember: Cerebrum for complex thoughts; cerebellum for balance and coordination.
According to the Centers for Disease Control and Prevention (CDC) which of the following is NOT an appropriate indication for insertion of an indwelling urinary catheter?
Houlry monitoring
End-of-life care
Bladder obstruction
Frequency of urination
Show the answer and explanation
Answer: D. Frequency of urination
Topic: Indwelling Catheter Indications
According to CDC guidelines, urinary frequency or incontinence without obstruction is not an appropriate indication for an indwelling catheter due to the high risk of infection. Catheters must only be used for specific, medically necessary indications.
Why the others are wrong
A – Hourly output monitoring in critically ill patients is a valid indication.
B – End-of-life care is a valid indication to provide comfort during palliative care.
C – Bladder obstruction is a valid indication to relieve acute urinary retention.
Remember: Catheters are for obstruction and critical care, not convenience or frequency.
The cerebral cortex is divided into four main lobes. These include:
Cerebellem, Diencephalon, Occipital, and Frontal
Diencephalon, Temporal, Parietal, and Occipital
Cerebellem, Hypothalamus, Occipital, and Temporal
Frontal, Temporal, Parietal, and Occipital
Show the answer and explanation
Answer: D. Frontal, Temporal, Parietal, and Occipital
Topic: Lobes of the Cerebral Cortex
The cerebral cortex is anatomically divided into four primary lobes: the frontal, parietal, temporal, and occipital lobes. These regions are responsible for integrating sensory, motor, and cognitive functions across the brain.
Why the others are wrong
A – The cerebellum and diencephalon are separate brain regions, not cerebral cortex lobes.
B – The diencephalon is a deep brain structure, not a lobe of the cerebral cortex.
C – The cerebellum and hypothalamus are distinct subcortical structures, not lobes of the cortex.
Remember: FTPO: Frontal, Temporal, Parietal, and Occipital lobes cover the cortex.
When conducting the patient interview to explore the chief complaint, the nurse identifies that it is best to use which style of questioning for data collection?
Closed-ended questions
Complex questions
Open-ended questions
Simple questions
Show the answer and explanation
Answer: C. Open-ended questions
Topic: Patient Interviewing Techniques
Open-ended questions encourage patients to describe their symptoms in their own words, providing comprehensive, detailed information about the chief complaint and preventing the nurse from leading the patient's responses.
Why the others are wrong
A – Closed-ended questions limit responses to 'yes' or 'no,' restricting detailed symptom exploration.
B – Complex questions confuse patients and often lead to inaccurate or incomplete clinical data.
D – Simple questions are useful but do not encourage detailed narrative descriptions of symptoms.
Remember: Open-ended questions let patients tell their story.
For patients with chronic respiratory conditions, such as COPD, the target range for SpO2 is often _________ SpO2 ranges for patients without chronic conditions.
Greater than
Equal to
Less than
Show the answer and explanation
Answer: C. Less than
Topic: Oxygen Therapy Targets
In chronic COPD, supplemental oxygen is titrated to maintain SpO2 88‑92%, lower than the usual 95‑100% for healthy individuals, to prevent hypercapnia from blunting hypoxic drive.
Why the others are wrong
A – Higher SpO2 can suppress respiratory drive in COPD patients.
B – Target is lower than normal, not equal to non‑COPD values.
The ability of the eye to adjust from near to far vision is known as:
Convergence
Accommodation
Nystagmus
Show the answer and explanation
Answer: B. Accommodation
Topic: Visual Accommodation
Accommodation is the process by which the eye's ciliary muscles adjust the curvature of the lens to focus clearly on objects at varying distances, specifically transitioning between near and far vision.
Why the others are wrong
A – Convergence is the inward movement of both eyes to focus on a close object.
C – Nystagmus is an involuntary, rapid, and repetitive movement of the eyes.
Remember: Accommodate means to adjust; the lens adjusts to focus near or far.
In order to reduce the risk of aspiration during tube feeding, the nurse understands that it is important to maintain the patient's head of bed to:
20-30 degrees
10-15 degrees
30-45 degrees
high fowlers
Show the answer and explanation
Answer: C. 30-45 degrees
Topic: Tube Feeding Aspiration Prevention
To prevent aspiration during enteral tube feeding, the head of the bed must be elevated to semi-Fowler's position, which is 30 to 45 degrees. This utilizes gravity to keep formula in the stomach and reduce reflux.
Why the others are wrong
A – This is insufficient; a minimum of 30 degrees is required to reduce aspiration risk.
B – This elevation is too low to effectively prevent gastric reflux and aspiration.
D – High Fowler's is unnecessary for feeding and increases the risk of skin breakdown.
Remember: Keep the head at thirty to forty-five to keep the lungs alive.
