Which of the following infection control measures is indicated in the patient with an active
methicillin resistant staphylococcus aureus wound infection?
A. Droplet precautions
B. Contact precautions
C. Protective isolation
D. Airborne precautions - correct answer-B. Contact precautions
Rationale: CDC recommends contact precautions for patients with active MRSA infection.
A patient with a hand wound caused by a high-pressure paint gun is awaiting surgical
wound exploration. Preoperatively, the emergency nurse will monitor the patient for the
development of
A. Lactic acidosis
B. Compartment syndrome
C. Tetanus infection
D. Muscle contracture - correct answer-B. Compartment syndrome
Rationale: High-pressure injection injuries occur when a device (e.g., a paint or grease gun)
injects the foreign substance into a body. This injury most commonly occurs to the
dominant hand or index finger of the injection gun operator. Emergency care includes
splinting the injury, obtaining radiographs, administering parenteral analgesics and broad-
spectrum ABX, ensuring appropriate tetanus prophylaxis, and elevating the injury. High-
pressure injection injuries are a surgical emergency requiring thorough cleansing and
immediate decompression to prevent compartment syndrome and tissue necrosis.
Hydrocarbon-based substances (e.g., fuel, paint thinners, organic solvents) cause the
most severe inflammatory response and are associated with the highest incidence of
subsequence amputations.
, Which of the following findings in a 20-yr-old burn patient indicates the need for burn
center referral?
A. 8% partial thickness burns to the anterior chest
B. Partial thickness burns on the anterior right thigh
C. 2% Full-thickness burns in the left knee area
D. Superficial circumferential burns of the forearms - correct answer-C. 2% Full thickness
burns in the left knee area
Rationale: According to the American Burn Association, patients with burns that overlay
major joints should be referred to a burn center.
A 5-year-old presents with dilated pupils, tachycardia, hot flushed skin, agitation,
diminished bowel sounds, urinary retention, and hallucinations after ingesting several
tiotropium (Spiriva) inhalation powder capsules. These findings suggest
A. Neurogenic shock
B. Diabetic ketoacidosis
C. Anticholinergic crisis
D. Beta-blocker overdose - correct answer-C. Anticholinergic crisis
Rationale: Symptoms of anticholinergic exposure can be recalled using the mnemonic "red
as a beet, dry as a bone, blind as a bat, mad as a hatter, and hotter than Hades." Treatment
is largely symptomatic and supportive.
After spraying pesticides all day, a farmhand walks into the ED complaining of diaphoresis,
productive cough, nausea, vomiting, and diarrhea. The priority intervention is
