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: The correct answer is B: To prevent cerebrospinal fluid (CSF) leakage. 1. Positioning is crucial to prevent CSF leakage as the spinal block is administered into the sub-arachnoid space where CSF is present. 2. Incorrect Answers: A: Positioning is not related to preventing confusion in this context. C: Seizures are not typically associated with spinal block anesthesia. D: Cardiac arrhythmias are not directly impacted by the client's positioning for a spinal block.

Correct Answer: C

Rationale: The correct answer is C: To rule out cholinergic crisis Neostigmine. Edrophonium HCL is a short-acting cholinesterase inhibitor used to differentiate between myasthenic crisis and cholinergic crisis, as both conditions present similarly with muscle weakness. Administering edrophonium HCL will help determine if the patient's worsening weakness is due to excessive cholinergic stimulation from neostigmine (cholinergic crisis) or inadequate acetylcholine at the neuromuscular junction (myasthenic crisis). This step is crucial for proper management, as treating cholinergic crisis with more cholinesterase inhibitors like neostigmine can worsen symptoms. Incorrect choices: A: For its synergistic effect - Edrophonium HCL does not have a synergistic effect with neostigmine. B: Because of the client's resistance to - Resistance to neostigmine is not a reason to administer edrophonium H

Correct Answer: A

Rationale: Correct Answer: A: Cover wound with moist sterile dressing Rationale: 1. Covering the wound with a moist sterile dressing helps maintain a clean and moist environment, promoting wound healing. 2. Moist dressing prevents the wound from drying out and minimizes the risk of infection. 3. The moist environment supports healing by promoting cell growth and preventing tissue damage. 4. It protects the exposed bowel from further injury and contamination. Summary: B: Finding out how this happened is important but not an immediate priority for patient care. C: Placing sterile dry gauze can lead to the wound drying out and hinder healing. D: Pouring sterile water into the wound is not recommended as it can introduce contaminants and is not considered standard care for this situation.

Correct Answer: A

Rationale: The correct answer is A because tachycardia (increased heart rate) and dilated pupils are classic responses of the sympathetic nervous system activation. Sympathetic nervous system is responsible for the fight or flight response, leading to increased heart rate and dilated pupils to prepare the body for quick action. Choice B is incorrect because hypoglycemia and headache are not specific to sympathetic nervous system function. Choice C is incorrect because increased peristalsis and abdominal cramping are more indicative of parasympathetic nervous system activity. Choice D is incorrect because pupil constriction and bronchoconstriction are actions of the parasympathetic nervous system, responsible for rest and digest functions.

Correct Answer: B

Rationale: The correct answer is B because rifampin can cause discoloration of bodily fluids, including tears. If clients wear contact lenses, they need to be informed that the lenses may become colored due to this medication. This is important for the client's awareness and to prevent any potential harm to their eyes. A: Taking medication with meals is not necessary for rifampin administration. C: Avoiding wearing glasses is not relevant to rifampin treatment. D: Avoiding tuna, aged cheese, and red wine is not specifically related to rifampin use.

Correct Answer: D

Rationale: The correct answer is D: throbbing headache. Nitroglycerin is a vasodilator that relaxes blood vessels, leading to increased blood flow and reduced workload on the heart. One common side effect of nitroglycerin is a throbbing headache due to the dilation of blood vessels in the brain. This side effect is expected and usually diminishes with continued use. Explanation of other choices: A: High blood pressure - Nitroglycerin actually helps lower blood pressure by dilating blood vessels. B: GIT irritation - This is not a common side effect of nitroglycerin, as it primarily affects the cardiovascular system. C: Shortness of breathing - This is not a typical side effect of nitroglycerin, as it does not directly affect respiratory function.

Correct Answer: D

Rationale: The correct answer is D: All of the above. Involvement of the sacral plexus can affect bladder control, leading to bladder problems. It can also impact bowel function, requiring bowel management. Additionally, the sacral plexus plays a role in sexual function, so assessment should include sexual activity. Therefore, all options are relevant when assessing a disease process involving the sacral plexus. Other choices are incorrect as they do not cover the comprehensive assessment needed for this specific condition.

Correct Answer: D

Rationale: The correct answer is D, suggesting the use of glasses or contact lenses. This is because as older clients experience lens changes associated with aging, they may develop presbyopia or other vision issues that can be corrected with corrective lenses. Glasses or contact lenses can help improve their vision and quality of life. A, offering teaching aids with large-sized letters, may be helpful for clients with visual impairments but may not directly address the specific lens changes associated with aging. B, suggesting reduced visual activity, is not beneficial as it may further limit the client's engagement in daily activities and social interactions. C, suggesting the use of eye drops for comfort, may provide temporary relief for dry eyes but does not address the underlying lens changes affecting vision.

Correct Answer: D

Rationale: The correct action for the nurse to take first is to obtain a Doppler and recheck the pedal pulses. This is the correct choice because it allows the nurse to further assess the circulation in the lower extremities. By using a Doppler, the nurse can accurately detect the presence or absence of pedal pulses, which is crucial in evaluating the severity of the patient's condition. This step provides objective data that can guide the next course of action. Choice A is incorrect because emergency surgery should not be anticipated without further assessment. Choice B is incorrect as assessing apical and radial pulses is not relevant in this situation. Choice C is incorrect as elevating the foot of the bed and applying warm compress may not address the underlying circulation issue.
