1. Test #4 Practice Questions

2. He developed pneumonia
A 15-year-old male is brought to the ER for treatment of injuries received in a motor vehicle accident. An MRI reveals spinal cord injury, and his body temperature fluctuates markedly. The most accurate explanation of this phenomenon is that:
He developed pneumonia
His sympathetic nervous system has been damaged, and thermal control disturbed
He has a brain injury
He has septicemia from an unknown source
This occurs because of the altered function of the autonomic nervous system. The higher the level of injury, the greater the tendency for fluctuations in your body temperature.

3. His sympathetic nervous system has been damaged, and thermal control disturbed

4. A 72-year-old male demonstrates left-sided weakness of upper and lower extremities. The symptoms lasted 4 hours and resolved with no evidence of infarction. The patient most likely experienced a(n):
Stroke in evolution
Arteriovenous malformation
Transient Ischemic Attack
Cerebral Hemorrhage

5. Transient Ischemic Attack

6. Urinary Tract Obstruction Nephrotic Syndrome
While planning care for a patient who has acute pyelonephritis, a nurse recalls the most common condition associated with the development of acute pyelonephritis is:
Cystitis
Renal Cancer
Urinary Tract Obstruction
Nephrotic Syndrome
Pyelonephritis is an inflammation of the kidney and upper urinary tract that usually results from noncontagious bacterial infection of the bladder (cystitis).

7. Urinary Tract Obstruction

8. A 42-year-old male is involved in a motor vehicle accident during which he loses a lot of blood. The nurse realizes he is in acute renal failure caused by:
Kidney stones
Immune complex deposition in the glomerulus
Inadequate renal blood flow
Obstruction of the proximal tubule

9. Inadequate renal blood flow

10. Which patient is most prone to multiple organ dysfunction syndrome (MODS)? In a patient with:
Myocardial infarction
Pulmonary disease
Septic shock
Autoimmune disease

11. Septic Shock

12. A 10-year-old male is given penicillin for an infection
A 10-year-old male is given penicillin for an infection. He has an allergic reaction, during which he develops urticarial lesions. These lesions are mediated by the release of:
Beta-adrenergic agonists
Histamine
Calcium
Cortisol

13. Histamine

14. A 28-year-old male is admitted to the burn unit 2 hours after receiving second- and third-degree burns over 50% of his body surface in an industrial explosion. Abnormal vital signs include low blood pressure and tachycardia. Lab results show a high hematocrit due to:
Sickle cell syndrome
Fluid movement out of the vascular space
Renal failure
Increased vascular protein secondary to increased metabolism

15. Fluid movement out of the vascular space
