A client is scheduled for a prostatectomy, and the anesthesiologist plans to use a spinal (sub-arachnoid) block during surgery. In the operating room, the nurse positions the client according to the anesthesiologist's instructions. Why does the client require special positioning for this type of anesthesia?

Correct Answer: B

Rationale: Special positioning is required for a spinal (sub-arachnoid) block to prevent cerebrospinal fluid (CSF) leakage. The client is usually positioned in either a sitting or lateral decubitus position to allow for easier access to the spinal canal and ensure proper administration of the anesthesia. Maintaining the correct positioning helps to minimize the risk of CSF leakage, which can result in headaches and potential complications postoperatively. By positioning the client appropriately during the procedure, healthcare providers can optimize the effectiveness of the spinal block while reducing the risk of adverse effects.

Correct Answer: A

Rationale: In the preoperative phase, one of the key roles of a nurse in patient care is to obtain preoperative orders. This involves ensuring that all necessary tests, medications, and procedures are in place before the surgery is performed. By obtaining preoperative orders, the nurse ensures that the patient is adequately prepared for the surgical procedure and that any potential risks or complications are minimized. This role requires attention to detail, clear communication with the healthcare team, and a thorough understanding of the patient's individual needs and medical history.

Correct Answer: D

Rationale: The primary sign of breast cancer is usually a painless mass or lump in the breast. This mass or lump may feel hard, irregularly shaped, and different from the surrounding breast tissue. It is important to note that not all breast lumps are cancerous, but it is crucial to seek medical evaluation if you notice any new or unusual changes in your breast tissue. Other signs such as a bloody discharge from the nipple, retraction of the nipple, or dimpling of the skin over the lesion can also be associated with breast cancer, but the presence of a painless mass in the breast is typically the most common initial indication of the disease.

Correct Answer: D

Rationale: An inotropic agent, such as digoxin, is a medication that strengthens the contraction of the heart muscle. It works by increasing the force of each heartbeat, helping the heart pump more efficiently. This can be beneficial in conditions such as heart failure or certain types of arrhythmias where the heart's pumping ability is compromised. Inotropic agents do not decrease heart rate, increase conduction time, or increase heart rate; their primary action is to enhance the heart's contractility.

Correct Answer: C

Rationale: Metolazone, a diuretic medication commonly known as Zaroxolyn, can cause electrolyte imbalances in the body, particularly low potassium levels which can lead to muscle weakness. Therefore, the nurse should instruct the patient to report any signs or symptoms of muscle weakness to the healthcare provider promptly. Numb hands, gastrointestinal distress, and nightmares are not common side effects of metolazone that typically require urgent medical attention.
