Question

A nurse asks the patient to follow a finger with their eyes. The patient is unable to move the eyes laterally.

Which cranial nerve is most likely impaired?

Answer 1

Correct Answers:

Cranial nerve VI

Rationale :

Cranial nerve VI controls the lateral rectus muscle of the eye.

👉 The lateral rectus is responsible for abducting the eye (moving it outward/laterally).

👉 If CN VI is impaired, the patient cannot move the eye laterally.

👉 This results in horizontal diplopia (double vision), especially when looking outward.

👉 The eye may drift medially due to unopposed action of the medial rectus muscle.

👉 It is commonly affected in conditions like increased intracranial pressure or trauma.

👉 The “follow my finger” test directly assesses extraocular movement function.

👉 Therefore, inability to move the eye laterally indicates CN VI dysfunction.

❌ Cranial nerve IV (Trochlear nerve)

👉 Controls the superior oblique muscle.

👉 Affects downward and inward eye movement, not lateral movement.

❌ Cranial nerve V (Trigeminal nerve)

👉 Responsible for facial sensation and chewing muscles.

👉 Does not control eye movement.

❌ Cranial nerve III (Oculomotor nerve)

👉 Controls most eye movements, pupil constriction, and eyelid elevation.

👉 Damage causes “down and out” eye position and ptosis, not isolated loss of lateral movement.

Answer 2

Correct Answers:

Temperature 99.0 F, pulse 88 bpm, respirations 18/min, blood pressure 118/76 mm Hg

Rationale :

This set of vital signs falls within normal adult ranges:

Temperature 99.0°F → within normal upper range (up to ~99.0°F)

Pulse 88 bpm → normal (60–100 bpm)

Respirations 18/min → normal (12–20/min)

Blood pressure 118/76 mm Hg → normal (around 120/80 mm Hg)

👉 All values are physiologically stable and within expected adult limits.

👉 There are no signs of fever, tachycardia, bradypnea, or hypertension/hypotension.

👉 This is the only option where all parameters align with normal adult vital sign ranges.

👉 Therefore, this patient has the most appropriate overall vital signs.

❌ Temperature 98.4°F, pulse 104 bpm, respirations 14/min, blood pressure 120/80 mm Hg

👉 Pulse 104 bpm = tachycardia (abnormal).

👉 Even though other values are normal, elevated heart rate disqualifies it.

❌ Temperature 97.9°F, pulse 76 bpm, respirations 22/min, blood pressure 112/70 mm Hg

👉 Respirations 22/min = tachypnea (above normal range).

👉 This indicates possible respiratory stress or anxiety.

❌ Temperature 98.6°F, pulse 60 bpm, respirations 12/min, blood pressure 122/84 mm Hg

👉 Pulse 60 bpm is low-normal but acceptable, but respirations 12/min is borderline low, and BP is slightly elevated diastolic (84 mm Hg).

👉 Not all parameters are clearly optimal within balanced normal limits.

Answer 3

Correct Answers:

Diaphoresis

Rationale :

Diaphoresis refers to profuse or excessive sweating.

👉 It is commonly seen in conditions such as pain, anxiety, fever, shock, or myocardial infarction.

👉 It results from activation of the sympathetic nervous system.

👉 The body releases sweat in response to stress or physiological imbalance.

👉 It is an important clinical sign of systemic distress.

👉 Nurses should document it accurately because it may indicate serious underlying conditions.

👉 It is not normal perspiration but pathologic excessive sweating.

👉 Therefore, diaphoresis is the correct term.

❌ Dyspnea

👉 Dyspnea means difficulty breathing or shortness of breath.

👉 It is a respiratory symptom, not sweating.

❌ Cyanosis

👉 Cyanosis refers to a bluish discoloration of skin due to low oxygen levels.

👉 It is unrelated to sweating.

❌ Ecchymosis

👉 Ecchymosis refers to bruising or bleeding under the skin.

👉 It has no relation to sweat production.

👉 Tests early cardiovascular compensatory response

👉 Assesses baroreceptor reflex activity

👉 Identifies early BP instability or volume depletion

👉 Allows partial redistribution of blood volume

👉 Detects dizziness or early symptoms of hypotension

👉 Provides intermediate comparison before standing

👉 Ensures safe progression to full upright position

🧍 3. Standing position measurement

👉 Creates maximum orthostatic stress on the body

👉 Causes blood pooling in lower extremities due to gravity

👉 Evaluates full autonomic compensation response

👉 Identifies orthostatic hypotension (key diagnostic step)

👉 Assesses cerebral perfusion under stress

👉 May trigger tachycardia as compensation

👉 Reveals symptoms like dizziness or syncope

👉 Provides the most clinically significant reading

📝 4. Documentation

👉 Records all BP readings for legal accuracy

👉 Provides comparison between all positions

👉 Communicates findings to healthcare team

Answer 5

Correct Answers:

Monitor intake and output and check electrolyte values.

Rationale :

Skin tenting over the sternum indicates poor skin turgor, a classic sign of dehydration.

👉 Dehydration leads to fluid volume deficit and electrolyte imbalance.

👉 Monitoring intake and output (I&O) helps determine the severity of fluid loss.

👉 Checking electrolytes (especially sodium, potassium, chloride) identifies internal imbalances.

👉 Older adults are at higher risk due to reduced thirst response and kidney function changes.

👉 Early detection prevents complications such as hypovolemia and dysrhythmias.

👉 Fluid and electrolyte monitoring guides replacement therapy decisions.

👉 Therefore, I&O and electrolytes are the priority.

❌ Auscultate lung sounds and respiratory status

👉 Lung assessment is important but not the primary concern of skin tenting.

👉 Tenting specifically indicates fluid loss, not primary respiratory dysfunction.

❌ Observe the anterior trunk for redness or ecchymoses

👉 This relates to skin integrity or trauma, not hydration status.

👉 It does not address the underlying issue of fluid deficit.

❌ Monitor for tenting on other areas of the body

👉 This is repetitive assessment but does not address cause or systemic effects.

👉 The priority is identifying fluid and electrolyte imbalance, not just confirming the sign.

Answer 6

Correct Answers:

Ecchymosis

Rationale :

Ecchymosis refers to discoloration of skin or mucous membranes caused by blood leaking into subcutaneous tissue.

👉 It typically appears as a flat, irregular purple, blue, or dark patch (bruising).

👉 It occurs due to capillary rupture or trauma.

👉 In mucous membranes, it indicates bleeding beneath the surface tissues.

👉 It is commonly seen in conditions like trauma, clotting disorders, or anticoagulant use.

👉 It differs from petechiae (tiny pinpoint spots) and hematomas (raised collections of blood).

👉 It is a key sign of tissue injury or bleeding tendency.

👉 Therefore, ecchymosis is the correct term.

❌ Dyspnea

👉 Dyspnea means difficulty breathing or shortness of breath.

👉 It is unrelated to skin or mucous membrane discoloration.

❌ Cyanosis

👉 Cyanosis is a bluish discoloration due to low oxygen levels in the blood.

👉 It is not caused by blood leaking into tissues.

❌ Diaphoresis

👉 Diaphoresis refers to excessive sweating.

👉 It is unrelated to bruising or blood extravasation.

Answer 7

Correct Answers:

Short, discrete, bubbling sounds on inspiration

Rationale :

Crackles (rales) are abnormal lung sounds caused by fluid in the alveoli or small airways.

👉 They are typically heard during inspiration when air opens fluid-filled alveoli.

👉 The sound is described as short, popping, or bubbling.

👉 They are commonly found in conditions like pneumonia, heart failure, or pulmonary edema.

👉 Since the patient condition is unchanged, the nurse would expect the same characteristic inspiratory crackles.

👉 Crackles indicate air moving through fluid or collapsed alveoli.

👉 They are not continuous like wheezes or harsh like stridor.

👉 Therefore, short bubbling inspiratory sounds are correct.

❌ Coarse gurgling on expiration

👉 This suggests secretions in larger airways, not alveolar crackles.

👉 Crackles are mainly inspiratory, not expiratory gurgles.

❌ High-pitched, musical sounds on inspiration

👉 This describes wheezes, caused by airway narrowing (e.g., asthma).

👉 Not related to fluid in alveoli.

❌ Grating sounds on expiration

👉 This suggests pleural friction rub, caused by inflamed pleural surfaces.

👉 It is not related to crackles.

Answer 8

Correct Answers:

Apply a water-based lubricant to the nares and assess the skin under the tubing each shift.

Rationale :

Oxygen therapy via nasal cannula can cause dryness and irritation of the nasal mucosa.

👉 A water-based lubricant helps moisturize and protect the nares from drying and cracking.

👉 Continuous oxygen flow can also cause skin breakdown from pressure of tubing.

👉 Regular assessment of the skin helps prevent pressure injuries on the ears, cheeks, and nares.

👉 This promotes patient comfort and tissue integrity.

👉 It is a key safety intervention during oxygen therapy at higher flow rates (like 5 L/min).

👉 Preventing complications is a priority nursing responsibility.

👉 Therefore, this is the most appropriate priority action.

❌ Encourage the client to remove the cannula while eating and reapply it afterward

👉 Removing oxygen can lead to decreased oxygen saturation and hypoxia.

👉 Oxygen should not be interrupted unless prescribed.

❌ Add humidification to the oxygen delivery system and verify proper prong fit in the nares

👉 Humidification is useful, but typically prioritized for higher flow or long-term oxygen use, not the immediate priority here.

👉 Proper fit is important but secondary to preventing skin breakdown.

❌ Increase the flow rate to 8 L/min if the client reports shortness of breath

👉 Increasing flow rate without a prescription can cause oxygen toxicity or CO₂ retention in susceptible patients (e.g., COPD).

👉 This is unsafe and requires provider order.

Answer 9

Correct Answers:

Difficulty breathing

Rationale :

Dyspnea refers to the subjective sensation of difficult or labored breathing.

👉 It is commonly described as shortness of breath or breathlessness.

👉 In emphysema, air trapping and alveolar damage reduce effective gas exchange, causing dyspnea.

👉 Patients feel like they cannot get enough air in or out.

👉 It is a hallmark symptom of chronic obstructive pulmonary disease (COPD).

👉 Dyspnea may occur at rest or with exertion depending on severity.

👉 It reflects impaired ventilation and oxygenation.

👉 Therefore, difficulty breathing is the correct definition.

❌ Pallor

👉 Pallor refers to pale skin coloration due to reduced blood flow or anemia.

👉 It is unrelated to breathing difficulty.

❌ Absence of retractions

👉 Retractions indicate respiratory distress, so absence of retractions is actually a normal finding.

👉 It does not define dyspnea.

❌ Cyanosis

👉 Cyanosis is bluish discoloration of skin due to low oxygen levels.

👉 It is a possible sign of hypoxia, but not the definition of dyspnea.

Answer 10

Correct Answers:

Place a "No Smoking-Oxygen in Use" sign on the client's door and at the bedside.

Rationale :

Oxygen is a highly combustible gas, meaning it greatly increases the risk of fire.

👉 Even a small ignition source (cigarettes, sparks, electrical devices) can cause a serious fire or explosion.

👉 Posting a warning sign ensures staff, visitors, and patients are aware of oxygen use.

👉 It is a key infection and safety control measure in oxygen therapy.

👉 This intervention directly reduces the risk of life-threatening fire hazards.

👉 It promotes environmental safety and hazard prevention.

👉 It is a standard nursing responsibility for any patient receiving oxygen.

👉 Therefore, this is the most important safety intervention.

❌ Encourage the client to use petroleum jelly to relieve nasal dryness

👉 Petroleum-based products are flammable and should NEVER be used with oxygen therapy.

👉 This increases risk of fire hazard in oxygen-rich environments.

❌ Increase the oxygen flow rate when the client reports shortness of breath

👉 Flow rate changes require a prescription and assessment, not automatic adjustment.

👉 Increasing oxygen unnecessarily can cause oxygen toxicity or CO₂ retention in some patients.

❌ Keep electrical equipment unplugged while oxygen is in use

👉 While electrical safety is important, this is not practical or required in standard care.

👉 The main risk is open flames and smoking, not routine electrical equipment.
