Q1
The home health nurse is assigned to visit these clients when a change in agency staffing requires that
one of the clients be rescheduled for a visit on the following day. Which client will be best to reschedule?
CORRECT ANSWER
Client with emphysema who has been on home oxygen for a month and has SpO2 levels of 91% to 93%
RATIONALE
• Oxygen saturation 91‑93% is stable for COPD/emphysema (target 88‑92%).
• Priority clients: those with acute changes, new procedures, or unstable vital signs.
• This client is stable and can safely be seen the next day.
Q2
A client with asthma reports shortness of breath. Which finding does the nurse anticipate when assessing
this client's chest?
CORRECT ANSWER
Expiratory wheezing not cleared by coughing
RATIONALE
• Asthma causes bronchospasm, leading to expiratory wheezing.
• Wheezing that does not clear with coughing suggests lower airway narrowing.
• Absence of wheezing in severe asthma may indicate "silent chest" (emergency).
, Q3
The nurse is assessing a client with chronic bronchitis who smoked 3 packs of cigarettes daily for 32
years. How does the nurse document pack‑year history of smoking in the medical record?
CORRECT ANSWER
96 pack‑year history (32 years × 3 packs/day = 96 pack‑years)
RATIONALE
• Pack‑years = (packs per day) × (years smoked).
• ≥20 pack‑years is a significant risk factor for COPD and lung cancer.
• Accurate documentation guides screening and treatment.
Q4
The nurse is caring for a client who just returned from an open lung biopsy and has a prescription for
morphine by patient‑controlled analgesia (PCA). Which action to detect early opioid‑induced respiratory
depression does the nurse recommend?
CORRECT ANSWER
Continuous capnography
RATIONALE
• Capnography detects changes in end‑tidal CO2 before pulse oximetry desaturation.
• Early sign of respiratory depression: rising ETCO2.
• Recommended for patients on PCA or high‑risk opioid therapy.
Q5
A client has just been admitted to the emergency department and requires high‑flow oxygen therapy
after suffering facial burns and smoke inhalation. Which oxygen delivery device will the nurse select?
CORRECT ANSWER
Face tent
RATIONALE
• Face tent delivers high flow without irritating burned facial tissue.
• Non‑rebreather mask may be painful or impossible to seal.
• Provides humidified oxygen; adjustable FiO2.
