This comprehensive test bank is designed for nursing students and professionals preparing
for the HESI Gerontology exam. It covers 400 multiple-choice questions with correct
answers and detailed rationales across key gerontology topics: respiratory,
cardiovascular, renal, neurological, gastrointestinal, integumentary, musculoskeletal,
endocrine, immune, psychosocial, medication management, and nutrition. Questions reflect
real-world clinical scenarios, prioritize safety, and emphasize age-related physiological
changes, pharmacology, and end-of-life care. Ideal for NCLEX-style practice,
remediation, and exam readiness.
SECTION 1: RESPIRATORY SYSTEM CHANGES IN AGING
1. A frail elderly woman visits the healthcare provider because she has been getting out
of breath easily when walking long distances. Which pulmonary function change should
the registered nurse (RN) expect to commonly occur with aging?
a) Decreased residual volume
b) Mild respiratory acidosis
c) Reduced vital capacity
d) Increased alveoli function
Correct Answer: c) Reduced vital capacity
Rationale: With aging, a frail elder is likely to have reduced vital capacity due to the loss
of elasticity of the lung tissue. With reduced elasticity, residual volume increases. Arterial
pH should not change with normal aging. A decrease, rather than an increase, in alveoli
function can occur due to a thinning of the alveolar walls with age.
2. An 80-year-old client reports increasing shortness of breath with minimal activity. Which
age-related structural change in the respiratory system contributes most significantly to this
symptom?
a) Enlargement of the trachea
b) Calcification of costal cartilage
c) Increased number of alveoli
d) Strengthening of respiratory muscles
Correct Answer: b) Calcification of costal cartilage
Rationale: Calcification of costal cartilage reduces chest wall compliance, making it harder
for the lungs to expand during inspiration. This contributes to dyspnea on exertion. The
1
,trachea does not typically enlarge with aging, alveolar numbers decrease, and
respiratory muscle strength declines rather than increases.
3. The nurse is assessing an 85-year-old client's respiratory status. Which finding is
considered a normal age-related change rather than a pathological one?
a) Barrel-shaped chest
b) Cyanosis of nail beds
c) Clubbing of fingers
d) Paradoxical breathing
Correct Answer: a) Barrel-shaped chest
Rationale: A barrel-shaped chest results from increased anteroposterior diameter due to
loss of lung elasticity and hyperinflation, which is common in aging. Cyanosis, clubbing,
and paradoxical breathing are always pathological and require immediate investigation.
4. An older client's arterial blood gas results show a PaO2 of 72 mmHg. The nurse
understands that this value is:
a) Indicative of severe respiratory failure
b) Within normal limits for an older adult
c) Suggestive of metabolic acidosis
d) A sign of acute respiratory distress
Correct Answer: b) Within normal limits for an older adult
Rationale: Normal PaO2 decreases with age. The formula is PaO2 = 104 - (age x 0.27).
For an 80-year-old, normal PaO2 would be approximately 82 mmHg, so 72 mmHg is
mildly reduced but not necessarily pathological and can be a normal age-related change.
5. Which intervention should the nurse prioritize for an older adult with reduced vital
capacity related to aging?
a) Encourage shallow breathing to conserve energy
b) Teach pursed-lip breathing techniques
c) Restrict fluid intake to prevent pulmonary edema
d) Place client in a supine position for optimal lung expansion
Correct Answer: b) Teach pursed-lip breathing techniques
Rationale: Pursed-lip breathing helps keep airways open longer during expiration,
improving gas exchange and reducing dyspnea. Shallow breathing is not recommended
as it worsens atelectasis. Supine positioning actually compromises lung expansion, and
fluid restriction is not indicated unless specific conditions exist.
6. An older client with chronic obstructive pulmonary disease (COPD) is being discharged.
Which statement indicates the client understands proper breathing techniques?
a) "I should breathe in quickly and forcefully."
b) "I will exhale through pursed lips like I am whistling."
c) "I need to hold my breath for 10 seconds after each inhale."
d) "I should breathe out as fast as possible."
Correct Answer: b) "I will exhale through pursed lips like I am whistling."
2
,Rationale: Pursed-lip breathing creates back pressure in the airways, preventing
premature collapse during expiration. Rapid or forceful breathing increases air trapping,
and breath-holding is not recommended for COPD clients.
7. The nurse is educating a group of older adults about respiratory health. Which
statement about smoking cessation is most accurate?
a) "Quitting smoking after age 70 provides no health benefits."
b) "Lung function can improve within weeks of quitting smoking."
c) "Smoking only affects the lungs, not other body systems."
d) "Nicotine patches are dangerous for older adults."
Correct Answer: b) "Lung function can improve within weeks of quitting smoking."
Rationale: Smoking cessation at any age provides significant health benefits, including
improved lung function, reduced inflammation, and decreased cardiovascular risk. The
benefits begin within weeks of quitting, making it never too late to stop smoking.
8. An older adult client is prescribed an inhaled corticosteroid for asthma management.
What teaching is essential for the nurse to provide?
a) "Rinse your mouth after each use to prevent oral thrush."
b) "This medication works immediately for acute attacks."
c) "You can stop using your rescue inhaler now."
d) "Take this medication only when you feel short of breath."
Correct Answer: a) "Rinse your mouth after each use to prevent oral thrush."
Rationale: Inhaled corticosteroids can cause oral candidiasis (thrush) due to local
immunosuppression. Rinsing the mouth after use significantly reduces this risk. These
medications are for maintenance, not acute relief, and should not replace rescue inhalers.
9. The nurse notes that an older client's respiratory rate is 28 breaths per minute and
shallow. What is the priority nursing action?
a) Document the finding as within normal limits
b) Assess oxygen saturation and lung sounds
c) Encourage the client to take deep breaths
d) Notify the healthcare provider immediately
Correct Answer: b) Assess oxygen saturation and lung sounds
Rationale: Tachypnea (rapid, shallow breathing) in an older adult is a sign of respiratory
distress that requires immediate assessment. The nurse should first gather more data by
checking oxygen saturation and auscultating lung sounds before notifying the provider or
implementing specific interventions.
10. Which age-related change in the respiratory system increases an older adult's risk for
pneumonia?
a) Increased cough reflex
b) Enhanced mucociliary clearance
c) Diminished immune function
d) Decreased residual volume
Correct Answer: c) Diminished immune function
3
, Rationale: Immunosenescence, the age-related decline in immune function, reduces the
body's ability to fight respiratory infections. The cough reflex actually decreases,
mucociliary clearance slows, and residual volume increases with aging, all contributing to
increased pneumonia risk.
11. An 82-year-old client is recovering from influenza. Which assessment finding indicates
the client may be developing pneumonia?
a) Temperature of 98.6°F (37°C)
b) Clear lung sounds bilaterally
c) Confusion and lethargy
d) Respiratory rate of 14 breaths per minute
Correct Answer: c) Confusion and lethargy
Rationale: Older adults often present with atypical symptoms of pneumonia, including
confusion, lethargy, and falls, rather than classic signs like fever and productive cough. A
normal temperature does not rule out infection, and clear lung sounds would not be
expected with pneumonia.
12. The nurse is assessing an older client's ability to use a metered-dose inhaler (MDI).
Which observation indicates the client needs further teaching?
a) The client shakes the inhaler before use
b) The client exhales completely before inhaling
c) The client depresses the inhaler while inhaling
d) The client holds the inhaler 2 inches away from the mouth
Correct Answer: d) The client holds the inhaler 2 inches away from the mouth
Rationale: A metered-dose inhaler should be held 1 to 2 finger-widths (about 1 inch) from
the mouth, or used with a spacer, for optimal medication delivery. Two inches is too far
and may result in medication being deposited in the oropharynx rather than the lungs.
13. Which laboratory finding would the nurse expect to see in an older adult with chronic
hypoxia?
a) Decreased hematocrit
b) Increased red blood cell count
c) Decreased white blood cell count
d) Increased platelet count
Correct Answer: b) Increased red blood cell count
Rationale: Chronic hypoxia stimulates erythropoietin production, leading to secondary
polycythemia (increased RBC count) as the body attempts to increase oxygen-carrying
capacity. Hematocrit would be elevated, not decreased, in this scenario.
14. An older client with a history of smoking reports a chronic cough with blood-tinged
sputum. What is the nurse's priority action?
a) Reassure the client this is normal with aging
b) Increase the client's fluid intake
c) Notify the healthcare provider immediately
d) Encourage deep breathing exercises
