  B. Diabetes Type II, new onset
  C. Emergency appendectomy
  D. Thyrotoxicosis
  C. Emergency appendectomy

  ---

  The nurse from the surgical care unit should be comfortable taking care of an emergency appendectomy patient. This nurse should be most comfortable with pre- and post-operative patients; therefore, the nurse should choose to give him or her those patients if available.

  A. Stimulating appetite
  B. Stimulating the patient to become more organized and motivated

  C. The patient becomes angry at her roommate for borrowing her clothes.
  D. The patient starts giving away her most prized possessions.
  D. The patient starts giving away her most prized possessions.

  ---

  The patient giving away her most prized possessions can be an indication that she is suicidal. The patient is saying good-bye with this gesture and hoping that someone will remember them when they are gone. This patient needs to be observed closely at this time to insure that they remain safe.

• Question 64:

  What would you want to assess your patient for if they have a myocardial infarction that is developing into cardiogenic shock?

  A. Ventricular dysrhythmia
  B. Bradycardia
  C. Rising diastolic blood pressure
  D. Falling central venous pressure
  A. Ventricular dysrhythmia

  ---

  The nurse would want to assess the patient for ventricular dysrhythmia. The left ventricle may have been damaged by the myocardial infarction, which could lead to left ventricular failure. The patient would have tachycardia, low blood pressure and rising central venous pressure.

• Question 65:

  Your patient has been diagnosed with a hyphema following hitting their head on the steering wheel during a car accident. What position would you want to place this patient in?

  A. Supine
  B. Semi- fowlers
  C. Lateral
  D. Trendelenburg
  B. Semi- fowlers

  ---

  The patient should be placed in semi-fowlers position on bed rest. A hyphema is caused by a force, such as hitting your head on the steering wheel, strong enough to break the blood vessels in the eye. Placing the patient in semi-fowlers position lets gravity work to keep the hyphema away from the optical center of the cornea.

• Question 66:

  Your patient with emphysema is receiving oxygen. What flow rate would you not want to exceed for this patient?

  A. 1 L/min
  B. 2 L/min
  C. 6 L/min
  D. 10 L/min
  B. 2 L/min

  ---

  The oxygen level for an emphysema patient should not exceed 2 L/min. The patient has been in a long- standing hypercapnia, which leads to the patient's drive to breathe being triggered by low oxygen levels. Too much oxygen would lead to the patient losing their drive to breathe.

• Question 67:

  What is the normal intraocular pressure of the eye?

  A. 2 to 7 mm Hg
  B. 10 to 21 mm Hg
  C. 22 to 30 mm Hg
  D. 31 to 35 mm Hg
  B. 10 to 21 mm Hg

  ---

  The normal intraocular pressure of the eye is 10 to 21 mm Hg. The test used to measure intraocular pressure is called a tonometry. This is how glaucoma is diagnosed. A patient with glaucoma would have an intraocular pressure of 30 to 70 mm Hg.

• Question 68:

  You are providing an education session for you unit on abuse of older patients. Which of the following patients is most likely to be an abused patient?

  A. A 90-year-old patient with advanced Parkinson's disease
  B. A 68-year-old patient with early Lyme disease
  C. A 70-year old-patient with newly diagnosed cataracts
  D. A 75-year-old patient with moderate hypertension
  A. A 90-year-old patient with advanced Parkinson's disease

  ---

  A 90 year old patient with advanced Parkinson's disease is more likely to be abused than any of the other patients. The typical patient to be abused would be one of advance age with few social contacts and at least one physical or mental impairment that limits the ability of the patient to perform activities of daily living.

• Question 69:

  You are caring for a patient who has been in a multiple trauma that has lead to severe blood loss. What type of device will you need to acquire to transfuse several units of blood quickly?

  A. Cardiac monitor
  B. Pulse oximetry
  C. Blood warming device
  D. Infusion controller
  C. Blood warming device

  ---

  In order to transfuse several units quickly without causing cardiac dysrhythmia, the nurse would need a blood warming device. Blood products must be warmed if they are going to be administered quickly. In this situation, the patient would not benefit from administering the blood slow.

• Question 70:
