Malcolm in the Middle Season 4 Episode 21

The paramedics showed up late because they stopped for coffee?

Lois asks Francis to help deliver the baby because he has experience delivering barn animals. This actually happens from time to time. In cases where doctors are absent but a veterinarian is near, they do have similar training that can help them to at least oversee the birth.

Hal has several hallucinations while under the influence of the diazepam. This is actually a common occurence at higher doses.

Hal is given 10mg of diazepam to immobilize him. It doesn't work, so the nurse can be seen to give him 3 more shots. That's a total of 40mg at one time, when the maximum recommended dosage is no more than 40mg per day split into three of four doses. A 40mg dose all at once has a high likelihood of causing a dangerous drop in blood pressure and can cause a person to stop breathing or their heart to stop beating. In severe cases, it can cause coma and even death.

The baby's gender is never given.

Francis is the one that delivers the baby.

Ida reveals to Lois that Victor has another family, which will be laid out more in next season episode, "Victor's Other Family."
