The nurse is teaching the mother of a 2-year-old client how to administer ear drops. The nurse recognizes correct return demonstration by the mother upon observing which technique?

A. To maintain moist wound healing: Hydrocolloid dressings contain gel-forming agents that react with wound exudate to create a protective, moist environment. This occlusive seal prevents tissue dehydration and promotes autolytic debridement by the body’s own enzymes. Maintaining moisture is critical for facilitating faster epithelialization and reducing pain at the site.

B. To create enzymatic debridement: Enzymatic debridement requires the application of external chemical agents, such as collagenase, to actively break down necrotic tissue. Hydrocolloids facilitate autolytic debridement by trapping endogenous moisture but do not contain extrinsic enzymes. They support the body’s natural processes rather than providing a chemical catalyst.

C. To absorb excessive wound drainage: Hydrocolloids have limited absorptive capacity and are unsuitable for heavily draining or "copious" wounds. Excessive exudate will cause the dressing to lose its seal or cause periwound maceration. They are best utilized for wounds with minimal to moderate drainage where moisture retention is desired.

D. To directly reduce bioburden (bacteria count): These dressings are not inherently antimicrobial and do not contain silver or iodine to kill pathogens. In fact, their occlusive nature can promote anaerobic bacterial growth if an active infection is present. They are primarily used for clean, granulating wounds rather than infected ones.

A. Dizziness: This is a common and often transient side effect of buprenorphine, especially during the induction phase of treatment. While it requires monitoring for patient safety and fall prevention, it does not typically constitute an acute clinical emergency. It is an expected pharmacological reaction to the initiation of therapy.

B. Headache: Cephalalgia is one of the most frequently reported side effects of sublingual buprenorphine/naloxone. It is usually manageable with non-opioid analgesics and does not indicate a failure of the induction process. It does not require immediate notification of the provider unless it is severe or neurological.

C. Muscle cramps: The presence of muscle cramps, along with other symptoms like diaphoresis or tachycardia, suggests that the client is experiencing precipitated withdrawal. Buprenorphine has a high affinity for mu-receptors and can displace full opioid agonists. This indicates the induction timing or dosage may need immediate medical adjustment.

D. Blood pressure of 126/89: This blood pressure reading represents a stable hemodynamic state and is not indicative of acute distress or severe withdrawal. While the diastolic pressure is at the high end of normal, it does not warrant an emergency call. It does not reflect the systemic instability of precipitated withdrawal.
