A nurse is assessing a client who has Parkinson's disease.
Which of the following manifestations should the nurse expect?

Choice A rationale

Localized erythema, along with warmth, swelling, and tenderness, is a cardinal sign of acute osteomyelitis. This inflammation is a direct result of the host's immune response to bacterial invasion within the bone. The increased blood flow to the affected area, mediated by inflammatory cytokines and vasodilatation, causes the characteristic redness and heat observed during the acute phase of infection.

Choice B rationale

Numbness of the toes on the affected foot is more indicative of neurological involvement or peripheral neuropathy rather than a primary manifestation of acute osteomyelitis. While severe swelling from osteomyelitis could potentially impinge on nerves, numbness is not a direct or common initial symptom of bone infection. Acute osteomyelitis primarily presents with inflammatory signs and systemic symptoms.

Choice C rationale

Bradycardia, an abnormally slow heart rate (typically below 60 beats per minute for adults), is not a typical manifestation of acute osteomyelitis. Acute infections, including osteomyelitis, commonly trigger a systemic inflammatory response, which usually leads to tachycardia, an elevated heart rate, as the body attempts to compensate for increased metabolic demands and fight the infection.

Choice D rationale

Hypothermia, a core body temperature below 35°C (95°F), is not a common manifestation of acute osteomyelitis. Instead, clients with acute osteomyelitis frequently present with fever, indicating a systemic inflammatory response to the infection. Hypothermia might occur in severe sepsis or septic shock, but it is not a direct or initial symptom of localized bone infection.

Choice A rationale

A seizure lasting greater than 5 minutes is a critical diagnostic criterion for status epilepticus. This prolonged duration signifies a failure of the normal inhibitory mechanisms that typically terminate seizure activity, necessitating urgent medical intervention to prevent potential neurological damage from sustained neuronal hyperexcitation.

Choice B rationale

Status epilepticus is not limited to only clonic type seizures. It can manifest as any type of seizure, including tonic, myoclonic, or absence seizures, occurring continuously or in rapid succession without full recovery of consciousness between episodes. This broad presentation highlights the diverse pathophysiology of uncontrolled neural discharge.

Choice C rationale

Sustained seizure activity in status epilepticus significantly increases metabolic demand and can lead to neuronal excitotoxicity and hypoxia. Prolonged oxygen deprivation and glucose depletion in brain tissue can result in irreversible neuronal injury and permanent structural brain damage, emphasizing the need for rapid intervention.

Choice D rationale

Status epilepticus is defined as a state of continuous seizure activity, or recurrent seizures without full recovery of consciousness between episodes. This persistent abnormal neuronal discharge in the brain signifies a medical emergency due to the high risk of neurological damage, systemic complications, and even mortality if untreated.
