A client with myasthenia gravis is malnourished. What actions to improve nutrition may the nurse delegate to the unlicensed assistive personnel (UAP)? (Select all that apply.)
- A. Assessing the client's gag reflex
- B. Cutting foods up into small bites
- C. Monitoring potassium levels
- D. Weighing the client daily
- E. Thickening liquids to prevent aspiration
Correct Answer: B,D
Rationale: Cutting food up into smaller bites makes it easier for the client to chew and swallow. The UAP can weigh the client daily to monitor nutritional status. Assessing the gag reflex and monitoring potassium levels are tasks that require nursing judgment and cannot be delegated to UAP. Thickening liquids is typically a nursing or dietary intervention, not a UAP task.
The nurse is preparing a client for a Tensilon (edrophonium chloride) test. What action by the nurse is most important?
- A. Administering anxiolytics
- B. Administering a ventilator
- C. Obtaining atropine sulfate
- D. Sedating the client
Correct Answer: C
Rationale: Atropine is the antidote to edrophonium chloride and should be readily available when a client is having a Tensilon test. The nurse would not want to give medications that might cause increased weakness or sedation. A ventilator may be needed, but emergency equipment should be available.
A client in the family practice clinic has restless leg syndrome. Routine laboratory work reveals white blood cells 8000 mm3, magnesium 0.8 mg/dL, and sodium 138 mEq/L. What action by the nurse is best?
- A. Advise the client to restrict fluids
- B. Assess the client for signs of infection
- C. Have the client add table salt to food
- D. Instruct the client on a magnesium supplement
Correct Answer: D
Rationale: Iron and magnesium deficiencies can exacerbate symptoms of restless leg syndrome. The client's magnesium level is low, and the client should be advised to add a magnesium supplement. The other actions are not needed based on the laboratory results.
The nurse caring for a client with Guillain-Barr?© syndrome has identified the priority client problem of decreased mobility for the client. What actions by the nurse are best? (Select all that apply.)
- A. Ask occupational therapy to help the client with activities of daily living
- B. Communicate with physical therapy for a consult
- C. Provide the client with information on support groups
- D. Refer the client to a medical social worker or chaplain
- E. Work with speech therapy to design a high-protein diet
Correct Answer: A,B,E
Rationale: Improving mobility and strength involves the collaborative assistance of occupational therapy, physical therapy, and speech therapy for nutritional support. While support groups, social work, or chaplain referrals may be needed, they do not directly help with mobility.
A client is taking long-term corticosteroids for myasthenia gravis. What teaching is most important?
- A. Avoid others who are ill
- B. Check blood sugars four times a day
- C. Use two forms of contraception
- D. Wear properly fitting socks and shoes
Correct Answer: A
Rationale: Corticosteroids reduce immune function, so clients taking these medications must avoid being exposed to illness. Long-term use can lead to secondary diabetes, but the client would not need to start checking blood glucose unless diabetes had been detected. Corticosteroids do not affect the effectiveness of contraception. While it is important to avoid injury, this is not specific to corticosteroid use.
