A nurse is evaluating a telemetry strip that shows an irregularly irregular rhythm, no identifiable P waves, and a ventricular rate of 110/min.
The client reports palpitations. How should the nurse document this strip in the medical record?

This scenario requires understanding of integumentary integrity and burn wound management. Knowledge of infection prevention and moist wound healing principles is essential. Partial-thickness burns involve the epidermis and dermis, necessitating protection of the newly exposed, vulnerable basement membrane to facilitate re-epithelialization.

Choice A rationale

. Antimicrobials prevent colonization of exposed dermis while nonadherent dressings maintain a moist environment. This facilitates cellular migration and prevents further trauma during future dressing changes. Protecting the bed from environmental pathogens is critical for healing and preventing secondary infection.

Choice B rationale

. Air exposure causes desiccation of the wound bed, which leads to cell death and delayed healing. Dry environments promote eschar formation, increasing the risk of scarring. Maintaining a moist interface is the gold standard for promoting rapid dermal repair.

Choice C rationale

. Dry gauze adheres to the wound exudate and causes significant tissue damage during removal. Tight application can also impair local capillary circulation, leading to ischemia. Dressings should be applied loosely enough to ensure adequate perfusion to the healing tissue.

Choice D rationale

. Intact blisters serve as a biological dressing, protecting the underlying dermis from infection. Removing them prematurely exposes the wound bed unnecessarily to the external environment. They should only be debrided if they are large enough to impede joint movement.

Identifying cardiac arrhythmias requires understanding the relationship between electrical conduction and mechanical output. Knowledge of pulse deficits is necessary to recognize when rapid, irregular atrial contractions fail to produce adequate ventricular filling and a palpable peripheral pulse.

Choice A rationale

Blood pressure discrepancies between the upper limbs usually indicate vascular issues like aortic dissection or peripheral arterial disease. Atrial fibrillation affects the rhythm and volume of the pulse rather than creating localized pressure differences between the arms.

Choice B rationale

Variations in lung sounds typically suggest localized pulmonary pathology such as pneumonia or pleural effusion. While atrial fibrillation can lead to heart failure and pulmonary edema, it does not specifically cause differences between upper and lower sounds.

Choice C rationale

A pulse deficit occurs when the apical heart rate is higher than the radial rate. In atrial fibrillation, some ventricular contractions are too weak to perfuse to the periphery, making this a classic assessment finding.

Choice D rationale

Discrepancies between oral and axillary temperatures relate to thermoregulation and measurement accuracy rather than cardiac rhythm. Temperature monitoring is used to screen for infection or inflammation but does not provide diagnostic information regarding atrial arrhythmias..
