A nurse is in the process of collecting a urine specimen for culture and sensitivity through straight catheterization.
Which step should the nurse take in this procedure?
Collect urine from the catheter’s port.
Use a sterile specimen container.
Inflate the balloon with sterile water.
Instruct the patient to clean from front to back with an antiseptic solution.
The Correct Answer is B
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.

Correct Answer is C
Explanation
Choice A rationale:
Dry skin is not typically associated with respiratory alkalosis. Respiratory alkalosis occurs when the levels of carbon dioxide and oxygen in the blood aren’t balanced. It occurs when you breathe too fast or too deep and carbon dioxide levels drop too low. This condition does not directly cause dry skin.
Choice B rationale:
Abdominal pain is not a common symptom of respiratory alkalosis. The condition is usually caused by over-breathing (called hyperventilation) that occurs when you breathe very deeply or rapidly. While it can cause discomfort, it does not typically result in abdominal pain.
Choice C rationale:
Diarrhea is not a direct symptom of respiratory alkalosis. However, the stress or anxiety that can cause hyperventilation and lead to respiratory alkalosis might also upset the digestive system and cause diarrhea. It’s important to note that while stress and anxiety can cause both conditions, they are not a direct result of the respiratory alkalosis itself.
Choice D rationale:
Flank pain is not a symptom of respiratory alkalosis. Flank pain is often associated with kidney problems, not respiratory conditions. Respiratory alkalosis is characterized by symptoms such as dizziness, bloating, feeling light-headed, numbness or muscle spasms in the hands and feet, discomfort in the chest area, confusion, dry mouth, tingling in the arms, heart palpitations, and feeling short of breath.
Correct Answer is A
Explanation
Choice A rationale:
Muscle twitching is a symptom of oxygen toxicity. Oxygen toxicity is a condition resulting from the harmful effects of breathing molecular oxygen (O2) at increased partial pressures. Severe cases can result in cell damage and death, with effects most often seen in the central nervous system, lungs, and eyes. Central nervous system symptoms can include muscle twitching.
Choice B rationale:
Redness of the face is not typically associated with oxygen toxicity. Oxygen toxicity primarily affects the central nervous system, lungs, and eyes. It does not typically cause redness of the face.
Choice C rationale:
Swelling around the eyes is not a common symptom of oxygen toxicity. The primary effects of oxygen toxicity are seen in the central nervous system, lungs, and eyes. However, this does not typically manifest as swelling around the eyes.
Choice D rationale:
A metallic taste in the mouth is not a known symptom of oxygen toxicity. Oxygen toxicity is a condition that results from the harmful effects of breathing molecular oxygen (O2) at increased partial pressures. It primarily affects the central nervous system, lungs, and eyes, but a metallic taste in the mouth is not a recognized symptom.
