The healthcare provider prescribes and IV solution of regular insulin (Humulin-R) 100 units in 250 ml of 0.45% saline to infuse at 12 units/hour. The nurse should program the infusion pump to deliver how many ml/hour?

Choice A: Yellow-tinged sputum is not a serious adverse effect of linezolid. It may indicate an infection or inflammation in the respiratory tract, but it does not require immediate attention from the health care provider.

Choice B: Nausea and headache are common side effects of linezolid. They are usually mild and self-limiting, and they can be managed with supportive measures such as hydration, rest, and analgesics.

Choice C: Watery diarrhea is a sign of pseudomembranous colitis, a potentially life-threatening complication of linezolid. It is caused by an overgrowth of Clostridium difficile bacteria in the colon, which produce toxins that damage the intestinal mucosa. It can lead to dehydration, electrolyte imbalance, sepsis, and perforation. The nurse should report this finding to the health care provider immediately and stop the linezolid infusion.

Choice D: Increased fatigue is not a specific or serious adverse effect of linezolid. It may be related to the underlying infection, anemia, or other factors. It does not require urgent intervention from the health care provider.

Choice A: Think about reasons the episodes occur. This is not the best instruction, as it may increase the anxiety level of the client. Thinking about reasons may trigger negative thoughts, emotions, or memories that can worsen the anxiety. The nurse should teach the client to focus on coping skills rather than causes.

Choice B: Center attention on positive upbeat music. This is not the best instruction, as it may not be effective for all clients. Listening to positive upbeat music may help distract or soothe some clients, but it may also irritate or annoy others. The nurse should teach the client to choose music that matches their mood and preference.

Choice C: Practice using muscle relaxation techniques. This is the best instruction, as it can reduce the physical symptoms of anxiety. Muscle relaxation techniques involve tensing and relaxing different muscle groups in a systematic way, which can lower blood pressure, heart rate, and breathing rate. The nurse should teach the client how to perform muscle relaxation techniques and practice them regularly.

Choice D: Find outlets for more social interaction. This is not the best instruction, as it may not be feasible or helpful for all clients. Finding outlets for more social interaction may help some clients feel supported or connected, but it may also stress or overwhelm others. The nurse should teach the client to seek social support that is appropriate and comfortable for them.
