A nurse is caring for a school-age child suffering from respiratory failure due to pneumonia.
Which position should the nurse recommend for maximum lung expansion?

Choice A rationale:

Collecting urine from the catheter’s port is not the correct procedure when collecting a urine specimen for culture and sensitivity through straight catheterization. The port is not a sterile environment and could contaminate the specimen, leading to inaccurate results.

Choice B rationale:

Using a sterile specimen container is the correct procedure. This ensures that the specimen is not contaminated by any external bacteria or substances, which could affect the results of the culture and sensitivity test. The container must be sterile to prevent the growth of microbes that are not present in the urine sample. This helps to ensure that the results of the culture are accurate and reflect the microbes present in the urine, not those introduced during collection.

Choice C rationale:

Inflating the balloon with sterile water is not a step in this procedure. The balloon is part of an indwelling catheter, not a straight catheter. An indwelling catheter remains in the bladder for a longer period, and the balloon is inflated to keep it in place. A straight catheter is used for a single voiding or to obtain a sterile urine specimen.

Choice D rationale:

Instructing the patient to clean from front to back with an antiseptic solution is not a step in this procedure. While maintaining cleanliness is important, this specific instruction is more relevant to a clean-catch midstream urine specimen, not a specimen collected through straight catheterization.

Choice A rationale:

Hypothermia, or abnormally low body temperature, is not typically a symptom of diarrhea. While it’s possible for a person with severe diarrhea to experience chills or feel cold, hypothermia is not a direct result of diarrhea.

Choice B rationale:

A rigid abdomen is often a sign of a serious condition like peritonitis (inflammation of the peritoneum, the tissue that lines the inner wall of the abdomen), but it is not typically associated with diarrhea.

Choice C rationale:

Dehydration is a common complication of diarrhea. When a person has diarrhea, they can lose a lot of fluid and electrolytes quickly, leading to dehydration. Symptoms of dehydration can include thirst, less frequent urination, dark-colored urine, fatigue, dizziness, and confusion.

Choice D rationale:

Decreased bowel sounds are not typically associated with diarrhea. In fact, bowel sounds may actually increase in some cases of diarrhea due to increased gut motility.
