Question 1

Regular sedation interruption is recommended for mechanically ventilated neurologic clients in order to:

Accepted Answer

Regular sedation interruption is recommended for mechanically ventilated neurologic clients in order to allow neurologic status assessment. This helps healthcare providers evaluate the patient's level of consciousness and assess any changes in their neurological status. Other reasons for sedation interruption may include evaluating the need for continued ventilatory support or assessing the patient's pain level, but these are not the primary reasons for sedation interruption in neurologic patients. Brain death determination is typically not done through sedation interruption.

Question 2

A positive apnea test determining brain death is based on:

Accepted Answer

A positive apnea test determining brain death is based on the lack of effort to breathe after discontinuation of mechanical ventilation.

Question 3

Craniotomy necessitates cutting of scalp hair.For which of the following clients should special consideration be explored preoperatively?

Accepted Answer

American Indian clients often have cultural beliefs and practices related to hair that necessitate special consideration before procedures like a craniotomy that involve cutting the hair. Hair is considered sacred and an extension of the self in many Native American cultures, and cutting it can have significant spiritual and emotional implications.

Question 6

Which of the following is an indicator of possible hypothalamic dysfunction?

Accepted Answer

The hypothalamus plays a crucial role in regulating body temperature. Altered body temperature can indicate hypothalamic dysfunction, as the hypothalamus is responsible for maintaining the body's homeostasis, including temperature regulation.

Question 7

Three criteria are used to determine brain death.These include absence of:

Accepted Answer

Brainstem reflexes are one of the key criteria used to determine brain death, along with absence of breathing and a flat electroencephalogram (EEG) recording. Absence of deep tendon reflexes, ventilator triggering, and pulse and blood pressure are not sufficient criteria to determine brain death.

Question 10

Explain why the use of labels such as "lethargic" or "confused" are insufficient when describing the neurologic client's status.

Accepted Answer

The answer of Explain why the use of labels such...

Question 11

Most cases of coma are due to what type of disorders?

Accepted Answer

The answer of Most cases of coma are due to...

Question 12

The reticular activating system controls

Accepted Answer

The reticular activating system (RAS) is a network of neurons in the brainstem that plays a crucial role in wakefulness and arousal. The RAS receives sensory inputs from the environment and internal body systems and relays this information to the cortex, which enables us to be alert and responsive to what is going on around us. The RAS is also involved in regulating attention, motivation, and mood. Therefore, it is the best choice out of the given options.

Question 13

Cerebral perfusion pressure (CPP)is determined by the following calculation:____________.

Accepted Answer

The answer of Cerebral perfusion pressure (CPP)is determined by the...

Identify two types of clients who may be misdiagnosed as comatose using the Glasgow Coma Scale.

Accepted Answer

The answer of Identify two types of clients who may...

Question 18

Which of the following are intracranial pressure waveforms indicating loss of intracerebral compliance?

Accepted Answer

DIntracranial pressure (ICP) waveforms consist of three peaks: P1 (percussion wave), P2 (tidal wave), and P3 (dicrotic wave). Normally, P1 is the highest, reflecting arterial pulsations. When intracerebral compliance decreases, the brain's ability to buffer changes in volume worsens, leading to alterations in these waveforms. A P2 greater than P1 indicates decreased compliance, as the brain's buffering capacity is overwhelmed, making the brain more susceptible to changes in blood volume. Similarly, a P3 greater than P1 and P2 indicates very poor compliance, as even the dicrotic wave, which normally is the smallest, becomes the largest, reflecting severely compromised brain compliance.

Question 19

The "Doll's eye reflex" is performed to test interactive integrity of the

Accepted Answer

Since extraocular muscle function requires client cooperation, this  test of integrity between the midbrain (CN IV and VI) and the pons (CN III) is performed on the  unconscious client.   A normal (positive)  response occurs if the eyes “lag” when the head is turned.
