charge nurse overhears a newly licensed nurse providing instructions to a female client on the proper steps to collect a midstream urine specimen. Which of the following statements made by the newly licensed nurse requires the charge nurse to intervene?
"Use the provided towelette to cleanse the area by moving in a back-and-forth motion."
"It will be easier to use your nondominant hand to spread the labia."
"Start the flow of urine before passing the container under the stream to collect the specimen."
"Remove the specimen container before stopping the stream of urine"
The Correct Answer is A
Choice A Rationale: The correct method for cleansing the area before collecting a midstream urine specimen is to wipe from front to back, not back-and-forth. This is to avoid contamination of the specimen with bacteria from the anal area. The towelette should be used in a single stroke and then discarded to ensure cleanliness.
Choice B Rationale: Using the nondominant hand to spread the labia is a standard practice that allows the dominant hand to manipulate the collection container. This technique helps to prevent contamination of the specimen by keeping the container away from the body and ensuring a clean catch.
Choice C Rationale: It is important to start the flow of urine before collecting the specimen to ensure that the 'midstream' urine is captured. This helps to flush out any bacteria that may be present at the opening of the urethra, reducing the risk of contaminating the sample.
Choice D Rationale: The specimen container should be removed from the stream before stopping the flow of urine to avoid contamination. The initial and final parts of the urine stream can carry bacteria from the urethra and skin, so only the midstream should be collected in the container.

Correct Answer is A
Explanation
a. Prothrombin time (PT): Warfarin affects the extrinsic pathway of the coagulation cascade, and PT is the primary diagnostic test used to monitor the therapeutic effect of warfarin. It measures
the time it takes for blood to clot.
b. Platelet count: Platelet count assesses the number of platelets in the blood and is not specifically used to monitor the effect of warfarin.
c. White blood cell count (WBC): WBC count assesses the number of white blood cells and is not specifically used to monitor the effect of warfarin.
d. Activated partial thromboplastin time (aPTT): While aPTT is a valuable test for monitoring the therapeutic effect of heparin, it is not the primary test for warfarin. Warfarin primarily affects the extrinsic pathway, and PT is more appropriate for monitoring its effects.
Correct Answer is D
Explanation
a. Blood glucose 150 mg/dL: While elevated blood glucose may be a concern, potassium levels are more critical in the context of acute gastroenteritis, which can lead to fluid and electrolyte
imbalances.
b. Urine specific gravity 1.035: Elevated urine specific gravity indicates concentrated urine and possible dehydration. However, the low potassium level takes precedence as it can lead to
serious cardiac complications.
c. Weight loss of 3% of total body weight: Weight loss is a concern, but the immediate risk of hypokalemia (low potassium) takes priority.
d. Potassium 2.5 mEq/L: This low potassium level is a critical finding that requires prompt attention, as it can lead to cardiac dysrhythmias and other serious complications.
