1. A patient with a history of severe chronic alcohol use disorder is
participating in an outpatient rehabilitation program and takes disulfiram
daily. During a home health visit, the patient reports severe facial flushing, a
throbbing headache, and intense vomiting after consuming a salad. Which
hidden ingredient should the nurse suspect as the trigger for this acute
reaction?
A. High-sodium processed bacon bits
B. A commercial salad dressing formulated with red wine vinegar
C. Aged cheddar cheese blocks containing tyramine
D. Synthetic artificial sweeteners inside a diet beverage
CORRECT ANSWER: B
RATIONALE: Disulfiram inhibits the enzyme aldehyde dehydrogenase,
causing a massive accumulation of toxic acetaldehyde if any form of alcohol is
ingested. Vinegars, including red wine vinegar, cider vinegar, and various salad
dressings, often contain residual alcohol fractions or undergo fermentation profiles
that trigger a severe Antabuse reaction characterized by flushing, headache, and
severe vomiting. Bacon bits (sodium), cheese (which affects MAOIs via tyramine),
and artificial sweeteners do not trigger the disulfiram-alcohol reaction.
2. The nurse is maintaining a closed chest tube drainage system for a patient
who is 12 hours post-operative following a left lower lobe lobectomy. While
checking the water seal chamber, the nurse observes continuous, vigorous
bubbling occurring inside the chamber. How should the nurse accurately
interpret and manage this finding?
A. Document the bubbling as an expected, normal finding indicating lung re-
, expansion.
B. Increase the wall suction pressure until the bubbling inside the chamber
stops entirely.
C. Identify the continuous bubbling as an active air leak within the
system and systematically check the connections.
D. Clamp the chest tube immediately at the insertion site using heavy-duty
forceps.
CORRECT ANSWER: C
RATIONALE: In a closed chest drainage system, intermittent bubbling in the
water seal chamber is normal during coughing or exhalation if an air leak from the
lung is resolving. However, continuous, vigorous bubbling indicates an active air
leak within the system drainage architecture or at the patient's insertion site. The
nurse must systematically check all connections to locate the leak. Clamping the
tube immediately without an order is dangerous as it can rapidly induce a tension
pneumothorax.
3. A 15-month-old toddler is brought to the pediatric well-child clinic for a
comprehensive developmental screening. Which gross motor or fine motor
milestone should the nurse identify as an expected baseline capability for a
child at this specific chronological age?
A. Walking independently across the room without assistance and
stacking two blocks.
B. Balancing entirely on one foot for 10 seconds and copying a circle.
C. Utilizing a tricycle to navigate around a designated obstacle course.
D. Cutting out shapes with safety scissors and tying shoelaces securely.
CORRECT ANSWER: A
RATIONALE: At 15 months of age, a typical toddler is expected to walk
independently without assistance and build a small tower of two blocks. Balancing
on one foot, copying shapes, and using safety scissors are complex developmental
milestones characteristic of preschool-aged children (3 to 5 years old). Navigating
a tricycle is an expected milestone for a 3-year-old child.
4. A patient with end-stage renal disease is undergoing peritoneal dialysis in
the outpatient unit. During the fluid instillation phase, the patient begins to
complain of acute, localized abdominal pain and the nurse notes the
dialysate return fluid is visibly cloudy and opaque. Which complication
, should the nurse anticipate, and what is the immediate priority?
A. Development of a mechanical catheter occlusion; turn the patient from
side to side.
B. Onset of acute peritonitis; obtain a sterile dialysate effluent sample
for culture and notify the provider.
C. Normal clearance of systemic urea fractions; accelerate the instillation
flow rate.
D. Sudden displacement of the internal peritoneal cuff; prepare the patient
for an emergency laparotomy.
CORRECT ANSWER: B
RATIONALE: A cloudy or opaque dialysate effluent return accompanied by
abdominal pain is the classic diagnostic indicator of acute peritonitis, a severe
infection of the peritoneal cavity. The nurse's immediate priority is to obtain a
sterile sample of the fluid for culture and sensitivity testing and report it to the
provider so intraperitoneal antibiotic therapy can be initiated. Turning the patient
or accelerating the rate will not resolve an infectious process.
5. A patient with a history of recurring deep vein thrombosis (DVT) is initiated
on oral warfarin therapy. To ensure accurate interpretation of clotting factors
and prevent medication errors, at what standard time of day should the nurse
instruct the patient to take this anticoagulant?
A. At exactly 0800 in the morning before breakfast.
B. In the late afternoon or evening at approximately 1700 hours.
C. Directly at midnight on an empty stomach.
D. Every 6 hours around the clock on a rigid schedule.
CORRECT ANSWER: B
RATIONALE: Warfarin is traditionally administered in the late afternoon or
evening, typically around 1700 hours. This scheduling is critical because it allows
the healthcare team to draw blood samples for Prothrombin Time (PT) and
International Normalized Ratio (INR) in the morning, receive the results, and
adjust the evening dose dynamically before the patient takes it. Morning or
midnight dosing delays safe dose adjustments.
6. The nurse is caring for a patient with advanced Parkinson's disease who
experiences severe xerostomia secondary to pharmacological interventions
and radiation exposure. Which nursing intervention should the nurse
