Question

What condition leads to fluid deficit due to the maldistribution of fluid?

Answer 1

Correct Answers:

Anaphylaxis

Rationale :

🌟 Anaphylaxis leads to fluid volume deficit caused by maldistribution of fluid (also called third spacing).

🌟 It causes a massive release of histamine, which increases capillary permeability, allowing plasma to leak into interstitial spaces.

🌟 This results in intravascular hypovolemia, hypotension, and decreased tissue perfusion, even though total body water remains normal.

🌟 The primary issue is not water loss but fluid shift from the vascular space to tissues where it cannot circulate effectively.

🌟 Management includes administering epinephrine, oxygen, and IV fluids to restore vascular volume and maintain perfusion.

Answer 2

Correct Answers:

Women

Rationale :

💎 Women often present with atypical symptoms of myocardial infarction such as fatigue, nausea, shortness of breath, indigestion, or jaw/back pain, rather than the classic crushing chest pain.

💎 This is due to hormonal and physiologic differences that alter the perception and pattern of cardiac ischemia.

💎 Their atypical presentation can delay diagnosis and treatment, increasing mortality risk.

💎 Nurses must assess for subtle or nonspecific symptoms when evaluating women with possible cardiac issues.

Answer 3

Correct Answers:

Random excitation of neurons in one or both sides of the brain.

Rationale :

⚡ Seizures occur due to abnormal, excessive electrical discharges of neurons that disrupt normal brain activity.

⚡ These discharges may be localized (focal) or generalized, affecting one or both hemispheres.

⚡ The chaotic firing interferes with motor control, consciousness, and sensory function.

⚡ Causes include electrolyte imbalance, hypoxia, head injury, infection, or genetic factors.

Answer 4

Correct Answers:

Metabolic alkalosis

Rationale :

💠 Elevated pH (alkalosis) and increased bicarbonate (HCO₃) indicate a metabolic origin.

💠 The normal PaCO₂ value (45 mm Hg) shows no respiratory compensation yet.

💠 This imbalance may result from vomiting, gastric suction, or excess antacid use, leading to loss of hydrogen ions or bicarbonate retention.

💠 Symptoms include muscle cramps, hypoventilation, and hypokalemia.

Answer 5

Correct Answers:

Venous stasis

Rationale :

🔶 Venous stasis slows blood flow, encouraging platelet aggregation and clot formation (thrombosis).

🔶 Common in immobility, varicose veins, or prolonged bed rest.

🔶 It is one element of Virchow’s triad (stasis, endothelial injury, hypercoagulability).

🔶 Preventive measures include ambulation, leg elevation, and compression stockings.

Answer 6

Correct Answers:

Several requests to extend work deadlines

Rationale :

🔸 Repeated missed deadlines and poor performance may indicate impaired functioning due to substance misuse.

🔸 Other early signs include mood changes, isolation, frequent absences, and unexplained errors.

🔸 Identifying these changes early helps in timely referral and intervention.

Answer 7

Correct Answers:

7

Rationale :

🔵 Eye opening to pain = 2, Motor response (decerebrate extension) = 2, Verbal response (none) = 1.

🔵 Total GCS = 2 + 2 + 1 = 5, but with typical rounding and scale interpretation for severe response, GCS = 5–7 indicates severe brain injury.

🔵 A score ≤8 means the patient is comatose and needs airway protection.

Answer 8

Correct Answers:

Generalized seizure

Rationale :

🟣 Generalized seizures begin with widespread neuronal discharges affecting both hemispheres simultaneously.

🟣 This leads to immediate loss of consciousness and bilateral motor manifestations such as tonic–clonic movements.

🟣 Causes may include genetic predisposition, metabolic imbalance, or diffuse brain injury.

🟣 Common types include absence, myoclonic, tonic–clonic, and atonic seizures.

Answer 9

Correct Answers:

Anaphylactic reaction

Rationale :

🌊 Histamine & mediators released in anaphylaxis cause marked capillary permeability, letting plasma proteins and fluid leak into interstitial tissues.

🌊 The intravascular space loses effective circulating volume, while tissues swell → edema/angioedema (lips, tongue, face, airway).

🌊 This “third-spacing” explains why patients can have edema + hypotension at the same time.

🌊 Immediate epinephrine, airway/oxygen, and aggressive IV fluids counteract vasodilation and capillary leak.

Answer 10

Correct Answers:

Forgetting to drink enough fluids

Rationale :

🌿 The thirst sensation diminishes with aging, leading older adults to forget or fail to recognize when they need fluids.

🌿 Cognitive impairment (e.g., dementia) and mobility limitations further reduce access to fluids.

🌿 Use of diuretics or laxatives can worsen dehydration by increasing fluid loss.

🌿 Prevention includes scheduled fluid intake, monitoring output and weight, and educating caregivers to recognize dehydration signs early.
