A female patient with a suspected urinary tract infection is to provide a clean-catch midstream urine specimen for culture and sensitivity testing. What should the nurse do to obtain the specimen?
Tell the patient to clean the urethral area, void a small amount into the toilet, then void directly into a sterile container.
Have the patient empty the bladder completely; then obtain the next urine specimen that the patient is able to void.
Clean the area around the patient's meatus with a povidone-iodine (Betadine) swab and then have the patient void into a sterile specimen cup.
Insert a short sterile "mini" catheter attached to a collecting container into the urethra and bladder to obtain the specimen.
The Correct Answer is A
Choice A rationale
This method is the standard procedure for obtaining a clean-catch midstream urine specimen. The initial voiding washes away organisms near the meatus, and the midstream urine is less likely to be contaminated by bacteria from the skin or urethral area, providing a sample that more accurately represents the bacteria in the bladder.
Choice B rationale
Having the patient empty the bladder completely and then obtaining the next specimen does not ensure a clean-catch sample. This method could lead to contamination of the specimen with bacteria from the skin or urethral area.
Choice C rationale
Cleaning the area with povidone-iodine is not recommended for routine urine culture as it may kill some of the bacteria, leading to a false-negative result. The standard practice is to clean the area with mild soap and water.
Choice D rationale
Inserting a catheter is an invasive procedure and is not the first choice for obtaining a urine specimen. It is used when a patient is unable to provide a clean-catch specimen or if there are specific medical indications.

Correct Answer is D
Explanation
Choice A rationale
A regular diet with no added salt may not be sufficient to address the fluid retention associated with acute glomerulonephritis and peripheral edema.
Choice B rationale
While a low-protein, low-potassium diet may be considered for certain kidney conditions, it does not specifically address the fluid and sodium management needed in acute glomerulonephritis with edema.
Choice C rationale
A low-carbohydrate, low-protein diet is not indicated in this scenario as it does not provide the necessary restrictions on sodium and fluid that are required for a child with edema and oliguria due to acute glomerulonephritis.
Choice D rationale
A low-sodium, fluid-restricted diet is most appropriate for a child with acute glomerulonephritis and peripheral edema. This diet helps manage the edema and prevent further fluid overload, which is crucial in the care of this condition.
Correct Answer is B
Explanation
Choice A rationale
Potassium levels are not directly affected by lactulose. While cirrhosis can lead to imbalances in electrolytes, including potassium, lactulose is not used to manage potassium levels in the bloodstream.
Choice B rationale
Ammonia is produced by the breakdown of proteins in the intestines and is normally processed by the liver. In cirrhosis, the liver's ability to convert ammonia to urea is impaired, leading to increased levels in the blood. Lactulose helps reduce blood ammonia levels by converting it into ammonium, which is then excreted.
Choice C rationale
Bicarbonate levels are related to the body's pH balance and are not the target of lactulose treatment. Cirrhosis does not typically result in bicarbonate imbalances that would be treated with lactulose.
Choice D rationale
Glucose levels are managed by insulin and other metabolic processes, not lactulose. While cirrhosis can affect overall metabolism, lactulose does not have a direct effect on blood glucose levels.
