A nurse is using a bladder scanner to measure the bladder volume of a patient who is experiencing frequent urination.
In what position should the nurse place the patient?
Sims’ position
Dorsal recumbent position
Supine position
High Fowler’s position
The Correct Answer is C
Rationale for Choice A:
Sims' position is a side-lying position with the lower arm and leg flexed and the upper arm and leg extended. It is not ideal for bladder scanning because it can displace the bladder and potentially lead to inaccurate readings. While it can be used for other purposes, such as inserting rectal suppositories or performing vaginal exams, it's not the optimal choice for bladder scanning.
Rationale for Choice B:
Dorsal recumbent position is a supine position with the knees bent and feet flat on the bed. While it provides some exposure of the bladder, it may not fully visualize the entire bladder due to potential compression from the abdominal contents. This can also result in inaccurate readings.
Rationale for Choice D:
High Fowler's position is a semi-sitting position with the head of the bed elevated at a 45- to 60-degree angle. This position is not suitable for bladder scanning because it can cause the bladder to shift upward and out of the optimal scanning range. It's typically used for respiratory comfort and procedures involving the head and upper body.
Rationale for Choice C:
Supine position is the best position for bladder scanning because it allows for the most accurate visualization of the bladder. In this position, the patient lies flat on their back with their legs extended. This position allows the bladder to rest naturally in the pelvic cavity, ensuring optimal positioning for the bladder scanner to capture a clear image and provide an accurate measurement of bladder volume. It also promotes patient comfort and relaxation during the procedure.

Correct Answer is ["C","D","E"]
Explanation
Choice A rationale:
Oral route anesthetic blocks are not considered regional anesthesia. They are a form of systemic anesthesia, meaning they affect the entire body.
Oral anesthetics are absorbed through the gastrointestinal tract and distributed throughout the bloodstream to reach their target sites in the central nervous system.
They produce a general depressant effect on the brain and spinal cord, leading to sedation, unconsciousness, and analgesia. Examples of oral anesthetics include benzodiazepines, barbiturates, and propofol.
Choice B rationale:
Inhalation anesthetic blocks are also a form of systemic anesthesia.
They are administered through inhalation of vaporized gases or volatile liquids.
These anesthetics rapidly cross the alveolar-capillary membrane in the lungs and enter the bloodstream, where they are transported to the brain and other tissues.
They produce a dose-dependent depression of the central nervous system, resulting in loss of consciousness, analgesia, and muscle relaxation.
Examples of inhalation anesthetics include nitrous oxide, sevoflurane, and isoflurane.
Choice C rationale:
Spinal anesthetic blocks are a type of regional anesthesia that involves injecting a local anesthetic directly into the subarachnoid space of the spinal cord.
This blocks nerve transmission in the spinal cord, resulting in loss of sensation and motor function in the lower half of the body.
Spinal anesthesia is commonly used for surgeries below the waist, such as cesarean deliveries, hip replacements, and knee surgeries.
Choice D rationale:
Epidural anesthetic blocks are another type of regional anesthesia that involves injecting a local anesthetic into the epidural space, which is the area surrounding the spinal cord.
This blocks nerve transmission in the spinal nerves, resulting in loss of sensation and motor function in a specific region of the body.
Epidural anesthesia is commonly used for labor and delivery, as well as for surgeries on the abdomen, pelvis, and lower extremities.
Choice E rationale:
Nerve anesthetic blocks (also known as peripheral nerve blocks) involve injecting a local anesthetic around a specific nerve or group of nerves.
This blocks nerve transmission in the targeted area, resulting in loss of sensation and motor function in a specific part of the body.
Nerve blocks can be used for a variety of surgical procedures, as well as for pain management.
Correct Answer is D
Explanation
Completing the Full Course of Antibiotics Is Essential to Prevent Recurrence and Antibiotic Resistance:
Eradication of Bacteria: Even though symptoms may have resolved, it's crucial to continue the full course of antibiotics to ensure complete eradication of the bacteria causing the UTI. Incomplete treatment can lead to:
Recurrence: Bacteria that haven't been fully eliminated can repopulate and cause a relapse of the infection. Antibiotic Resistance: Bacteria can develop resistance to the antibiotic, making future infections more difficult to treat. Specific Considerations for Nitrofurantoin:
Bacterial Suppression: Nitrofurantoin works primarily in the bladder, so it's essential to maintain adequate levels for a sufficient duration to fully suppress bacterial growth and prevent reinfection.
Delayed Symptom Resolution: In some cases, symptom resolution may lag behind bacterial eradication. Continuing the full course ensures treatment even if symptoms haven't completely subsided.
