A client who weighs 65 kg receives a prescription for lorazepam 44 mcg/kg intravenously to be administered 20 minutes before a scheduled procedure. The medication is available in 2 mg/mL vial. How many mL should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["1.4"]
Calculate the total dosage required: 44 mcg/kg * 65 kg = 2860 mcg. Convert mcg to mg: 2860 mcg ÷ 1000 = 2.86 mg.
Divide by concentration: 2.86 mg ÷ 2 mg/mL = 1.43 mL.
Considering the vial contains 2 mg/mL, the nurse should administer around 1.43 mL, which can be rounded to 1.4 mL.

Correct Answer is ["B","C","D"]
Explanation
A) Incorrect- Standard precautions are used for all clients to prevent the spread of infections.
However, in the case of MRSA, contact precautions are needed due to the risk of direct transmission through physical contact.
B) Correct- Monitoring the white blood cell count is important to assess for signs of infection, as an elevated count might indicate an ongoing inflammatory response.
C) Correct- Foul-smelling drainage from an incision with suspected MRSA indicates a potential infection. Contact precautions are appropriate for MRSA, which include wearing gloves and gowns when entering the client's room to prevent the spread of the bacteria.
D) Correct- Sending wound drainage for culture and sensitivity helps identify the specific microorganisms causing the infection and guides appropriate antibiotic treatment.
E) Incorrect- A low-bacteria diet is not relevant to the situation. MRSA is caused by a bacterium, not by dietary factors. The focus should be on infection control measures and appropriate medical interventions.
Correct Answer is A
Explanation
Following a pneumonectomy, it is important for the client to gradually resume normal activities and engage in social interactions. Encouraging family gatherings can provide emotional support, facilitate social connections, and help reduce feelings of isolation that the client may be experiencing.
While it is generally important for clients who have undergone a pneumonectomy to take precautions to reduce the risk of respiratory infections, such as avoiding crowded places and individuals with respiratory infections, completely avoiding social contact for several weeks is not necessary or realistic in most cases. It is essential to find a balance between protecting the client's health and promoting their emotional well-being and social integration.
Wearing a face mask during family events may not be necessary unless there is a specific concern about respiratory infections. The nurse can educate the client about the importance of good hand hygiene and avoiding close contact with individuals who are actively ill with respiratory infections.
