2026/2027 Verified Study Questions and Answers
Elaborate Rationales GRADE A+
1.
A person recovering from abdominal surgery reports severe incisional pain and is hesitant to
cough or take deep breaths, resulting in shallow respirations and oxygen saturation of 90%.
Which intervention should be implemented to prevent pulmonary complications?
A. Encourage deep breathing exercises only
B. Apply a heating pad for comfort
C. Administer prescribed analgesics before assisting with deep breathing and coughing
D. Document pain and reassess later
Rationale: Pain inhibits lung expansion, increasing the risk of atelectasis or pneumonia.
Administering analgesics before pulmonary exercises enables safe participation. Heat or
encouragement alone does not address the risk of complications.
2.
During morning rounds, a person with chronic obstructive pulmonary disease reports sudden
wheezing, shortness of breath, and increased purulent sputum after exposure to smoke. Oxygen
saturation is 87%. Which intervention is most important to prevent respiratory failure?
A. Encourage ambulation to clear secretions
B. Position upright, administer prescribed bronchodilator, and notify provider
C. Restrict fluid intake
D. Document findings and reassess in one hour
Rationale: Acute exacerbations of COPD can quickly lead to hypoxemia. Upright positioning
and bronchodilator therapy improve airflow and oxygenation, while provider notification ensures
timely intervention. Ambulation or fluid restriction alone does not address the airway
compromise.
3.
A young adult with type 1 diabetes reports dizziness, sweating, and confusion two hours after
insulin administration without eating. Blood glucose is 42 mg/dL. Which intervention is most
appropriate to prevent hypoglycemia complications?
,A. Encourage rest
B. Provide fast-acting carbohydrates such as juice or glucose tablets
C. Administer long-acting insulin
D. Monitor blood glucose
Rationale: Hypoglycemia can rapidly lead to seizures, unconsciousness, or cardiac
complications. Fast-acting carbohydrates restore glucose promptly. Rest or long-acting insulin
alone does not treat acute hypoglycemia.
4.
During evening care, a resident with dementia becomes agitated and attempts to remove IV lines.
Which intervention prioritizes safety while preserving dignity?
A. Apply restraints immediately
B. Assess for unmet needs, discomfort, or pain and provide calm reassurance
C. Call security
D. Ignore the behavior
Rationale: Agitation often reflects unmet needs or discomfort. Assessment and reassurance
safely de-escalate behavior. Restraints should only be used as a last resort due to potential
physical and psychological risks.
5.
A patient receiving total parenteral nutrition develops fever, chills, and hypotension. Which
intervention is most important to prevent sepsis?
A. Increase TPN infusion rate
B. Stop TPN, maintain IV access with saline, and notify provider immediately
C. Administer antipyretics only
D. Document findings
Rationale: Fever and chills suggest central line infection. Stopping TPN prevents worsening
infection, maintaining IV access ensures hydration, and timely provider notification allows for
cultures and treatment to prevent sepsis.
6.
During morning rounds, a patient with chronic heart failure reports sudden shortness of breath,
peripheral edema, and a weight gain of 3 kg in two days. Oxygen saturation is 86%. Which
intervention should be prioritized?
,A. Encourage ambulation
B. Notify provider for assessment and possible diuretic adjustment
C. Restrict fluids independently
D. Document and monitor
Rationale: Rapid fluid accumulation indicates worsening heart failure. Timely provider
notification ensures intervention to prevent pulmonary edema. Ambulation or unsupervised fluid
restriction does not address the underlying problem.
7.
A patient post-abdominal surgery reports nausea, vomiting, and abdominal distention. Bowel
sounds are absent. Which intervention is most appropriate to prevent aspiration and
gastrointestinal complications?
A. Encourage clear liquids
B. Apply heat for comfort
C. Keep NPO, maintain IV fluids, and notify provider
D. Document findings and monitor
Rationale: Absent bowel sounds with nausea and vomiting suggest ileus or obstruction. NPO
status prevents aspiration, IV fluids maintain hydration, and provider notification allows timely
intervention to prevent worsening gastrointestinal complications.
8.
A person with Parkinson’s disease coughs and chokes on a spoonful of applesauce, showing mild
cyanosis around the lips. Which intervention should be implemented immediately to ensure
airway safety?
A. Encourage continued eating slowly
B. Stop feeding, maintain upright position, and provide prescribed thickened liquids
C. Offer water
D. Document and monitor
Rationale: Cyanosis indicates acute aspiration risk. Upright positioning and thickened liquids
promote safe swallowing. Ignoring symptoms or offering water could result in aspiration
pneumonia.
9.
A post-hip replacement patient reports sudden calf pain, swelling, and redness. Which
intervention is most critical to prevent pulmonary embolism?
, A. Encourage ambulation
B. Apply heat
C. Limit leg movement and notify provider immediately
D. Document findings
Rationale: Calf pain and swelling suggest deep vein thrombosis. Limiting leg movement
prevents clot dislodgment. Timely provider notification ensures rapid treatment to prevent life-
threatening pulmonary embolism.
10.
A patient with type 2 diabetes reports dizziness, sweating, and palpitations one hour after insulin
injection and skipping a meal. Which intervention is immediate priority?
A. Encourage rest
B. Administer fast-acting carbohydrate
C. Give long-acting insulin
D. Monitor blood glucose
Rationale: Hypoglycemia can rapidly lead to seizures, unconsciousness, or cardiac
complications. Fast-acting carbohydrate restores glucose promptly. Rest or long-acting insulin
alone does not correct acute hypoglycemia.
11.
A person recovering from abdominal surgery reports severe incisional pain and avoids deep
breathing, causing shallow respirations and oxygen saturation of 91%. Which intervention
should be implemented to prevent respiratory complications?
A. Encourage only passive coughing
B. Apply heat for comfort
C. Administer prescribed analgesics prior to assisting with deep breathing and coughing
D. Document and monitor
Rationale: Pain inhibits lung expansion, increasing risk of atelectasis or pneumonia. Analgesics
allow the person to participate in pulmonary exercises safely. Heat or passive encouragement
alone does not address the underlying risk.
12.
During morning rounds, a person with chronic obstructive pulmonary disease experiences
sudden wheezing, shortness of breath, and thick, green sputum after exposure to environmental
smoke. Oxygen saturation is 86%. Which intervention is most important to prevent respiratory
failure?
