  D)
  Tetany, new-onset seizure activity, emotional lability, and extrapyramidal symptoms

Question 2

Following an automobile accident where the patient had a traumatic amputation of his lower leg and lost greater than 40 of his blood volume, he is currently not producing any urine output.
 
  The nurse bases this phenomena on which of the following humoral substances responsible for causing severe vasoconstriction of the renal vessels?

Answer to Question 1

Ans:
A

Feedback:

SCLS is associated with several types of paraneoplastic syndromes, including Cushing's. Answer choice B refers to superior vena cava syndrome; answer choice C refers to hypercalcemia; and answer choice D refers to tumor lysis syndrome. All of these are complications that can occur with cancer and treatment of cancer.

Answer to Question 2

Ans:
B

Feedback:

Increased sympathetic activity causes constriction of the afferent and efferent arterioles and thus a marked decrease in renal blood flow. Intense sympathetic stimulation can produce marked decreases in renal blood flow and GFR. Humoral substances, including angiotensin II, ADH, and endothelins, produce vasoconstriction of renal blood flow. Aquaporin-2 channels, potassium ions, and albumin do not have vasoconstriction properties.
