The neuroleptic drug haloperidol (Haldol) is the most frequently used drug to treat delirium in palliative care settings and may reduce hallucinations and agitation at the end of life.

A

Terminally Ill Patient meds

86
Q

nurse should consult w/the interprofessional team about discontinuing measures that no longer contribute to pt comfort, such as drawing blood, administering tube feedings, suctioning (in most cases), & invasive monitoring.

made through a physical examination that includes auscultation for the absence of breathing & heart sounds.

A

determination of death

88
Q

The lethal tumor dose is defined as the dose that will eradicate 95% of the tumor yet preserve normal tissue.

A

Radiation Dosage

89
Q

the total radiation dose is delivered over several wks in daily doses called fractions. This allows healthy tissue to repair and achieves greater cell kill by exposing more cells to the radiation as they begin active cell division.

A

In external-beam radiation therapy (EBRT)

90
Q

allow for the periphery of the tumor to be reoxygenated repeatedly, because tumors shrink from the outside inward. This increases the radiosensitivity of the tumor, thereby increasing tumor cell death

A

Repeated radiation Tx over time (fractionated doses)

91
Q

widely used form of systemic brachytherapy that is the primary Tx for thyroid cancer

A

93
Q

used as a form of radioimmunotherapy for the Tx of refractory non-Hodgkin lymphoma.

A

Radioisotopes

94
Q

 UTI’s
 Cardiac dysrhythmias (ventricular ectopy, tachycardia, & heart blocks), Complications of immobility
 Hyperglycemia has been associated w/ poor neurologic outcomes in acute stroke, therefore blood glucose should be in the range of 140 to 180 mg/dL.
