The nurse questions the wound care specialist about the meaning of an un-stageable pressure injury. Which statement about this condition is correct?
The slough or eschar that covers the wound hides a stage 3 or 4 pressure injury.
The wound presents with various areas that are between stages of the healing process.
The pressure injury is so early in the tissue destruction process that staging cannot be determined.
There is persistent non-blanchable purple discoloration that makes it difficult to determine the correct stage.
The Correct Answer is A
A. The slough or eschar that covers the wound hides a stage 3 or 4 pressure injury: Clinical staging requires full visualization of the wound base to determine the depth of tissue involvement. Necrotic tissue like slough or eschar physically obstructs the view of the underlying anatomy. Until this debris is debrided, the true extent remains unknown.
B. The wound presents with various areas that are between stages of the healing process: Pressure injury staging is based on the maximum depth of anatomical damage observed at its worst point. Healing wounds are not "back-staged" but rather described by their current characteristics. Mixed presentation does not render a wound unstageable under standard protocols.
C. The pressure injury is so early in the tissue destruction process that staging cannot be determined: Early tissue destruction is actually easily staged as a Stage 1 injury if erythema is present. Unstageable refers to the inability to see the bottom of the wound, not a lack of progression. Even early injuries are classified by their clinical presentation.
D. There is persistent non-blanchable purple discoloration that makes it difficult to determine the correct stage: This specific description defines a deep tissue pressure injury (DTPI) rather than an unstageable one. DTPI involves intact skin with deep discoloration reflecting internal damage. Unstageable specifically requires the presence of obscuring material like slough or eschar.

Correct Answer is A
Explanation
A. Higher amounts of free drug in the body may lead to toxicity: Many medications are highly protein-bound, primarily to albumin. Malnutrition causes hypoalbuminemia, leaving fewer binding sites available for the drug molecules. This increases the concentration of pharmacologically active "free" drug, significantly elevating the risk of toxic effects.
B. Since the body's metabolism is slower, less drug is required: While metabolic rates may fluctuate, the primary concern in malnutrition is the change in drug distribution and protein binding. Decreased hepatic enzyme activity may occur, but the immediate risk stems from high free drug levels. Protein availability is the dominant pharmacokinetic factor here.
C. Serum protein levels are higher than normal, requiring less medication: Malnutrition is characterized by protein-energy deficits, which lead to decreased serum albumin and total protein levels. Higher protein levels would actually lead to more drug binding and less free drug. This choice contradicts the physiological reality of the malnourished state.
D. The action is not correct since a malnourished person requires more medication to be effective: Increasing the dose for a malnourished client would be dangerous and potentially lethal. With fewer transport proteins, even standard doses can become toxic. Reducing the dose is a necessary safety precaution to account for increased drug bioavailability.
Correct Answer is B
Explanation
A. I will take my pulse before taking this pill: Monitoring the pulse is a standard requirement for medications like digoxin or beta-blockers, not oral opioids. While opioids can cause respiratory depression, they do not typically require routine heart rate checks by the client at home. This indicates a misunderstanding of the drug's primary side effects.
B. I will increase my intake of fiber in my diet: Opioids like oxycodone significantly decrease gastrointestinal motility by binding to mu-receptors in the enteric nervous system. This lead to a high incidence of opioid-induced constipation in post-operative patients. Increasing dietary fiber and fluid intake is a critical non-pharmacological strategy to mitigate this effect.
C. I will cut back on my intake of coffee and diet soda: While caffeine might interfere with sleep, it is not a direct contraindication for taking oxycodone and acetaminophen. There is no specific requirement to eliminate these beverages during a 1-week course of analgesics. This statement does not reflect core safety teaching for opioid use.
D. I should take this pill with dairy products to enhance its absorption: Dairy products do not enhance the absorption of oxycodone or acetaminophen and can sometimes delay it. Some medications have specific interactions with calcium, but these analgesics are not among them. Taking them with food is only recommended to reduce potential gastric upset.
