CBRN Pharmacology & Medication Management 3

Question 1

Tight glycemic control with insulin infusion in major burn patients is used primarily to:

Accepted Answer

Correct stress-induced hyperglycemia, reduce infection rates, and improve protein metabolism

Answer

Manage pre-existing diabetes exclusively

Answer

Prevent hyperosmolar states from enteral nutritional support

Answer

Reduce fluid requirements during early resuscitation

Question 2

The current standard multimodal pain management approach for burn patients includes:

Accepted Answer

Combination of opioids, non-opioids (acetaminophen, NSAIDs), and adjuncts (ketamine, gabapentin)

Answer

Opioids alone with escalating doses as tolerance develops

Answer

NSAIDs exclusively to avoid opioid-related side effects

Answer

Epidural analgesia as the primary and sole modality

Question 3

Gabapentin is increasingly used as an adjunct analgesic in burn patients primarily to treat:

Accepted Answer

Neuropathic pain and pruritus (itching) during wound healing

Answer

Acute procedural pain during dressing changes

Answer

Post-operative pain in the first 24 hours exclusively

Answer

Background resting pain in the acute resuscitation phase

Question 4

Topical bacitracin ointment is most appropriately used for which burn wound scenario?

Accepted Answer

Superficial burns on the face or around the eyes

Answer

Full-thickness burns requiring deep eschar penetration

Answer

Infected deep partial-thickness burns with heavy bacterial burden

Answer

Donor site wounds with confirmed Pseudomonas colonization

Question 5

Dexmedetomidine (Precedex) is used in burn ICU patients because it provides:

Accepted Answer

Sedation and analgesia with minimal respiratory depression, allowing patients to remain rousable

Answer

Deep neuromuscular blockade for ventilator synchrony

Answer

Complete amnesia for all painful ICU procedures

Answer

Rapid reversal with flumazenil if oversedation occurs

Question 6

N-acetylcysteine (NAC) is used in burn patients with inhalation injury primarily because it acts as:

Accepted Answer

A mucolytic and antioxidant to reduce airway secretion burden and oxidative damage

Answer

An antibiotic to prevent secondary pneumonia

Answer

An opioid antagonist to reverse respiratory depression

Answer

A hepatoprotectant against antibiotic-induced liver toxicity

Question 7

When administering systemic antibiotics to burn patients, the burn nurse should anticipate that dosing requirements will typically differ from standard dosing because:

Accepted Answer

Higher doses and/or more frequent dosing are needed due to increased volume of distribution and augmented renal clearance

Answer

Lower doses are needed due to impaired renal clearance from burn-related AKI

Answer

Standard doses require no adjustment in burn patients

Answer

Oral antibiotics are preferred to avoid IV line-associated infections
