,NGN Question 1 (Recognize Cues)
The Practical Nurse (PN) reviews Beatrice Vance's clinical intake records, vital signs,
and laboratory panels. Which group of subjective and objective cues confirms severe
orthostatic hypovolemia and hypertonic dehydration?
A) Hyperactive bowel sounds, body temperature of 37.8°C, and a blood glucose of 165
mg/dL.
B) A blood pressure drop from 92/58 to 78/44 mmHg upon standing, a heart rate
of 124 bpm, serum sodium of 149 mEq/L, and skin tenting.
C) Confusion to time and complaints of a throbbing headache alone.
D) A history of Type 2 Diabetes Mellitus and atrial fibrillation tracking.
Answer: B) A blood pressure drop from 92/58 to 78/44 mmHg upon standing, a
heart rate of 124 bpm, serum sodium of 149 mEq/L, and skin tenting.
Rationale: A drop in systolic blood pressure >20 mmHg or diastolic blood pressure >10
mmHg upon standing confirms orthostatic hypotension secondary to severe
intravascular fluid volume depletion. Tachycardia (124 bpm) is a compensatory reflex to
maintain cardiac output. A serum sodium level >145 mEq/L (hypernatremia) paired with
skin tenting proves hypertonic water loss exceeding solute loss, confirming intracellular
and extracellular dehydration.
NGN Question 2 (Take Action / Prioritization)
The healthcare provider prescribes emergency fluid resuscitation and medication
updates. Which immediate action falls within the safe scope of practice for the PN to
implement first?
A) Encourage the client to rapidly drink 1,000 mL of ice-cold plain tap water.
B) Establish fall precautions, sit the client upright, and prepare to administer
ordered intravenous isotonic crystalloids with monitored potassium replacement
at the directed infusion rate.
C) Administer a double dose of the client's home oral antidiabetic medication.
D) Insert an indwelling urinary catheter and obtain a sterile sample for heavy metal
toxicant screening.
Answer: B) Establish fall precautions, sit the client upright, and prepare to
administer ordered intravenous isotonic crystalloids with monitored potassium
replacement at the directed infusion rate.
Rationale: The client's profound orthostatic hypotension and confusion pose an
immediate safety and fall hazard, making fall precautions mandatory. Resuscitating a
severely dehydrated client with low potassium (3.1 mEq/L) requires careful intravenous
fluid tracking; rapid fluid shifts without monitored potassium can precipitate fatal cardiac
arrhythmias, especially given her history of atrial fibrillation.

Question 3
A PN on a medical-surgical floor is monitoring a client who returned from a subtotal
thyroidectomy 6 hours ago. The client reports numbness and a tingling sensation
around their mouth and inside their fingertips. The nurse notes a carpopedal spasm
when inflating the blood pressure cuff. What is the priority nursing intervention?
A) Reassure the client that muscle twitching is an expected post-anesthesia effect.
B) Ensure an emergency tracheostomy tray is at the bedside, notify the charge
nurse/provider immediately, and prepare to administer ordered intravenous
Calcium Gluconate.
C) Increase the delivery rate of oral pain relievers.
D) Place the client in a completely flat, prone layout to protect the incision.
Answer: B) Ensure an emergency tracheostomy tray is at the bedside, notify the
charge nurse/provider immediately, and prepare to administer ordered
intravenous Calcium Gluconate.
Rationale: Numbness around the mouth (perioral paresthesia) and carpopedal spasms
during blood pressure cuff inflation (Trousseau's sign) are classic signs of critical
hypocalcemia. This occurs if the parathyroid glands are accidentally injured or removed
during a thyroidectomy. Hypocalcemia causes severe neuromuscular irritability; if
unmanaged, it can cause laryngospasm and complete airway occlusion. Intravenous
calcium gluconate must be readily available to restore safe mineral balances.
Question 4
The PN is preparing to administer a scheduled dose of oral Digoxin (Lanoxin) to a
client with a history of congestive heart failure. The client reports new-onset anorexia,
nausea, and blurred vision where objects appear to have "green-yellow halos" around
them. What action must the PN take?
A) Administer the digoxin dose with a full glass of milk to settle the stomach.
B) Withhold the medication, measure the apical pulse for a full 60 seconds, and
immediately report the symptoms to the charge nurse and provider to check
serum digoxin and potassium levels.
C) Double the dose to boost cardiac output and relieve the visual fog.
D) Document the symptoms as standard age-related macular changes.
Answer: B) Withhold the medication, measure the apical pulse for a full 60
seconds, and immediately report the symptoms to the charge nurse and provider
to check serum digoxin and potassium levels.
, Rationale: Gastrointestinal distress (nausea, anorexia) and visual disturbances—
specifically seeing green-yellow halos or experiencing blurred vision—are classic
warning indicators of digoxin toxicity. Digoxin has an incredibly narrow therapeutic
index. The nurse must hold the drug, check the apical pulse to rule out severe
bradycardia, and coordinate diagnostic serum lines immediately.
Question 5
A client on bed rest following an extensive pelvic fracture suddenly reports sharp,
localized chest pain, severe dyspnea, and has an oxygen saturation of 88% on room
air. What is the correct clinical interpretation, and what immediate action should the PN
execute?
A) The client is developing atelectasis; instruct them to perform vigorous incentive
spirometry exercises.
B) The client is showing signs of an acute pulmonary embolism (PE); apply high-
flow oxygen, elevate the head of the bed, notify the provider immediately, and
enforce absolute bed rest.
C) The client is experiencing an anxiety attack; administer a low-dose sedative.
D) Place a warm heating pad directly over the client's chest wall to relieve muscle strain.
Answer: B) The client is showing signs of an acute pulmonary embolism (PE);
apply high-flow oxygen, elevate the head of the bed, notify the provider
immediately, and enforce absolute bed rest.
Rationale: Deep vein thrombosis (DVT) leading to a pulmonary embolism is a high-risk
complication for clients on prolonged bed rest following pelvic or long-bone fractures.
Sudden chest pain, tachypnea, and critical hypoxia indicate a clot has detached and
occluded pulmonary arterial segments. The nurse must prioritize immediate
oxygenation, optimize breathing mechanics by sitting the client up, and enforce strict
immobility to prevent further clot mobilization.
Question 6
The PN is caring for a client who is 12 hours post-operative following an abdominal
cholecystectomy. The client states, "I felt a sudden pop in my stomach when I
sneezed." Upon removing the surgical dressing, the nurse notes that the wound
margins have fully separated and a loop of the small intestine is protruding outside the
skin. What is the correct sequence of emergency interventions?
A) Gently push the loop of bowel back inside the abdominal cavity and tape the skin
edges together tightly.
B) Place the client in a low-Fowler's position with their knees bent, cover the
protruding visceral organs with sterile dressings saturated in warm normal
saline, and notify the surgeon immediately.
C) Instruct the client to stand up and walk around the room to see if gravity realigns the
tissue.
D) Administer high-volume oral liquids to keep the intestinal tract hydrated.
Answer: B) Place the client in a low-Fowler's position with their knees bent, cover
the protruding visceral organs with sterile dressings saturated in warm normal
