A nurse is caring for a client who has cholelithiasis with bile duct obstruction. The nurse should expect which of the following findings when obtaining the client's urine specimen?

Bright orange

Dark-amber

Pale yellow

Red

Answer and Explanation

The Correct Answer is B

A.   Bright orange urine could be caused by certain medications, such as rifampicin and phenazopyridine or food dyes, such as those containing carotene.
B.   This is because the obstruction of the bile duct leads to an accumulation of bilirubin in the blood, which is then excreted in the urine, giving it a darker color.
C.   Pale yellow urine is indicative of normal urine coloration and is not specific to bile duct obstruction.

D.   Red urine could indicate the presence of blood, which might suggest other conditions such as urinary tract infections or kidney stones, but not typically bile duct obstruction.

Correct Answer is A

Explanation

A. Three or more consecutive premature ventricular contractions (PVCs) on an ECG tracing is indicative of ventricular tachycardia, a serious arrhythmia that requires prompt intervention.
B. Bigeminy refers to a pattern of every other beat being a PVC, not necessarily three or more consecutive PVCs.
C. Ventricular fibrillation is characterized by chaotic, disorganized ventricular activity on the ECG and is not defined by the presence of consecutive PVCs.
D. Trigeminy refers to a pattern of every third beat being a PVC, not necessarily three or more consecutive PVCs.

A. To reduce risk of infection B. To dry gastric secretions C. To promote postoperative healing D. To correct a clotting problem

Correct Answer is D

Explanation

A. While vitamin K plays a role in immune function, its administration prior to surgery primarily aims to correct potential clotting abnormalities rather than prevent infection.

B. Vitamin K does not affect gastric secretions. Its role in this context is unrelated to gastric function.
C. While vitamin K is involved in various physiological processes, its administration prior to surgery is primarily aimed at preventing bleeding complications by ensuring adequate clotting factor synthesis.
D. Vitamin K is essential for the synthesis of clotting factors in the liver.

Administering vitamin K prior to surgery helps ensure adequate levels of clotting factors, reducing the risk of bleeding during and after the procedure.
