A client with osteoarthritis of the hips and knees has received instructions on how to use a walker for ambulation.
Which behavior observed by the nurse indicates the client understands the instructions?
The client uses the walker to get up from the chair and looks down at his feet to prevent falling.
The client bears weight on both feet when moving the walker ahead and steps with the weaker leg first.
The client places her full weight on the walker with her arms while taking steps to prevent pressure on her lower extremity joints.
The client leans forward at a 60-degree angle while stepping into the walker but looks ahead at where he is going.
The Correct Answer is B
The client bears weight on both feet when moving the walker ahead and steps with the weaker leg first. This is the proper way to use a walker for ambulation, as it provides stability and reduces stress on the affected joints.
Choice A is wrong because the client should not look down at his feet to prevent falling, but rather look ahead at where he is going. Looking down can cause neck strain and loss of balance.
Choice C is wrong because the client should not place her full weight on the walker with her arms while taking steps, as this can cause upper extremity fatigue and injury. The client should use the walker as a support, not a crutch.
Choice D is wrong because the client should not lean forward at a 60-degree angle while stepping into the walker, as this can cause back pain and poor posture. The client should stand upright and move the walker forward about one step’s length at a time.

Correct Answer is B
Explanation
Face the client while speaking and ask them to verify understanding. This intervention would help the client to read the nurse’s lips and confirm the message.
It would also show respect and empathy for the client’s condition.
Choice A is wrong because using exaggerated mouth and hand movements when speaking can be distracting and insulting to the client.
It can also distort the words and make them harder to understand.
Choice C is wrong because standing in front of a light when speaking to the client can create glare and make it difficult for the client to see the nurse’s face.
Touching the client to be sure they know where you are can be startling and unnecessary if the client is not visually impaired.
Choice D is wrong because obtaining an interpreter for sign language is inappropriate unless the client knows sign language.
Not all hearing-impaired clients use sign language, and some may prefer other methods of communication.
Correct Answer is D
Explanation
Insulin regular (Humulin-R) is the only form of insulin that is safe for intravenous administration. This is because it is a short-acting insulin that has a rapid onset and peak time, and does not contain any additives or suspensions that could interfere with the infusion.
Choice A is wrong because insulin aspart (Novo Log) is a rapid-acting insulin that is usually taken right before a meal. It is not suitable for intravenous use because it has a different amino acid sequence than human insulin.
Choice B is wrong because insulin glargine (Lantus) is a long-acting insulin that covers insulin needs for about a full day. It is not suitable for intravenous use because it forms micro-precipitates under the skin that release insulin slowly and steadily.
Choice C is wrong because insulin lispro (Humalog) is a rapid-acting insulin that is usually taken right before a meal. It is not suitable for intravenous use because it has a different amino acid sequence than human insulin.
