  a. Subarachnoid bolt or screw
  b. Subdural or epidural catheter
  c. Intraventricular catheter
  d. Fiberoptic transducer tipped catheter

Question 2

A patient becomes unresponsive. The patient's heart rate is 32 beats/min, idioventricular rhythm; blood pressure is 60/32 mm Hg; SpO2 is 90; and respiratory rate is 14 breaths/min. Which of the following interventions would the nurse do first?
 
  a. Notify the physician and hang normal saline wide open.
  b. Notify the physician and obtain the defibrillator.
  c. Notify the physician and obtain a temporary pacemaker.

Answer to Question 1

C
An intraventricular catheter allows accurate intracranial pressure (ICP) measurement and provides access to cerebrospinal fluid (CSF) for drainage or sampling. A subarachnoid bolt or screw is less accurate to measure high ICP elevations and provides no access for CSF sampling. A subdural or epidural catheter may have baseline drift over time causing possible loss of reliability or accuracy and provides no access for CSF drainage or sampling. A fiberoptic transducer tipped catheter cannot be recalibrated after placement and provides no access for CSF sampling or drainage.

Answer to Question 2

C
If the sinus node and the atrioventricular (AV) junction fail, the ventricles depolarize at their own intrinsic rate of 20 to 40 times per minute. This is called an idioventricular rhythm and is naturally protective mechanism. Rather than trying to abolish the ventricular beats, the aim of treatment is to increase the effective heart rate (HR) and re-establish dominance of a higher pacing site such as the sinus node or the AV junction. Usually, a temporary pacemaker is used to increase the HR until the underlying problems that caused failure of the other pacing sites can be resolved.

The modern decimal position system was the invention of the Hindus (around 800 AD), involving the placing of numerals to indicate their value (units, tens, hundreds, and so on).

Not getting enough sleep can greatly weaken the immune system. Lack of sleep makes you more likely to catch a cold, or more difficult to fight off an infection.

Did you know?

It is believed that the Incas used anesthesia. Evidence supports the theory that shamans chewed cocoa leaves and drilled holes into the heads of patients (letting evil spirits escape), spitting into the wounds they made. The mixture of cocaine, saliva, and resin numbed the site enough to allow hours of drilling.

Vital signs (blood pressure, temperature, pulse rate, respiration rate) should be taken before any drug administration. Patients should be informed not to use tobacco or caffeine at least 30 minutes before their appointment.

Did you know?

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).
