I usually like to have a protein shake after a workout to rebuild any muscles lost. Is a shake with 42 grams fine?
That may be a bit more protein than your body can utilize for repairing and building muscle at any one time (any one meal), but protein has other uses as well. According to some tests the body can only use about 30 grams of protein at any one time for muscle repair. The amount varies a bit depending on how big you are. Listen to the audio in the link below which addresses your question.
Sure....That much protein in a post workout smoothie is fine.
As long as you don't take in more than double your body weight in grams of protein you're probably just fine. No worries.
It's good you ask about it though. A lot of gym rat types, especially your self proclaimed power lifters, are too obsessed with protein and they often overdo it a tad.

Ultimately, making sure you hit your protein goals for the day (should be about 0.85 to 2.00 grams per pound of LBM depending on specifics) is more important than when you take it.
With that said, there is nothing wrong with using that shake or similar shakes.

Don't worry about getting too much protein from supplements you drink. Most of it will be utilized as carbohydrate or stored as fat. The amino acids from soybeans, powdered milk or other sources, will have been degraded by oxidation during dehydration or other processing and also during the time after that, before they are consumed.
The production of protein supplements is a big business and those who profit from it, act outraged when they hear this. But a study into food technology will reveal how quickly the loss of protein quality takes place. Recently, research showed that cold meats will have lost most of their usable protein during processing and from being saturated with preservatives. Here's a couple of links where many of the negative aspects of using protein supplements are discussed. Pay special attention to the 2nd link, where the phytoestrogens in soybeans are described. The use of hexane gas in defatting ground soybeans and extracting the protein from them, is very harsh and damaging. Originally, isolated soy protein was not developed to be used for food, but rather to be a component in paints and glues.

Short answer is that your fine taking in that much protein in one sitting. Objective scientific studies have found that there is no real upper limit to protein absorption:

Sorry but that upper limit of grams of protein per LMB you listed is a myth. Your body never needs that much protein. Even 1.25 grams/LB is overkill! All the objective scientific studies with no outside agenda have shown that .85 grams/LB is the upper limit even for professionals such as strength/endurance athletes.
With that said, I'm not saying that there is any disadvantage to taking in excessive protein. Just saying that there is no point in being miserable by forcing yourself to take in excessive protein everyday. If you want a very detailed explanation of this read the article below:
In fact based on those studies 1 grams/LB is more then enough. So any extra protein you take in beyond that has no benefits in terms of gaining mass when bulking or retaining muscle when cutting. On a side note that website has the most accurate and honest advice I have ever found on the internet regarding fitness in 16 years. I would encourage everyone to check out the articles there.
Human males need a minimum of 56 grams of protein a day. If you are working out daily you need more. If you are older, then your body doesn't assimilate protein as well as it used to, and you need more.
