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.

A. Atrial depolarization B. Atrial repolarization C. Ventricular depolarization D. Ventricular repolarization

Correct Answer is A

Explanation

A. The P wave on an ECG represents atrial depolarization, which occurs as the electrical impulse originates in the sinoatrial (SA) node and spreads through the atria, initiating atrial contraction.
B. Atrial repolarization typically occurs during the QRS complex and is not represented by the P wave. Atrial repolarization is masked by the larger QRS complex.
C. Ventricular depolarization is represented by the QRS complex on an ECG, as the electrical impulse spreads through the ventricles, leading to ventricular contraction.
D. Ventricular repolarization typically occurs during the T wave and is not represented by the P wave. Ventricular repolarization involves the recovery of ventricular muscle cells after contraction.
