The components required for bacterial protein synthesis are:

1. mRNA, tRNA, and 80S ribosomes.
2. mRNA, tRNA, and 70S ribosome.
3. DNA, mRNA, cell wall, and nucleoid.
4. mRNA, tRNA, plasma membrane, and pili.

Question 2

1. Do not become pregnant while on ampicillin.
2. If taking oral contraceptives, use an alternative form of birth control.

Answer to Question 1

Correct Answer: 2
Rationale 1: The 80S ribosome is located in human cells.
Rationale 2: Three components are required for bacterial protein synthesis: messenger ribonucleic acid (mRNA), transfer ribonucleic acid (tRNA), and the 70S ribosome (subunits 30S and 50S).
Rationale 3: DNA and nucleoids are not among the three components required for bacterial protein synthesis.
Rationale 4: Pili, hairlike projections on the surface of some bacteria, are not among the three components are required for bacterial protein synthesis.
Global Rationale: Three components are required for bacterial protein synthesis: messenger ribonucleic acid (mRNA), transfer ribonucleic acid (tRNA), and the 70S ribosome (subunits 30S and 50S). The 80S ribosome is located in human cells. DNA and nucleoids are not among the three components required for bacterial protein synthesis. Pili, hairlike projections on the surface of some bacteria, are not among the three components are required for bacterial protein synthesis.

Answer to Question 2

Correct Answer: 2,3,4
Rationale 1: Ampicillin is a category B drug and is safe to use while pregnant.
Rationale 2: Ampicillin can decrease the effectiveness of oral contraceptives.
Rationale 3: Food decreases the absorption of ampicillin.
Rationale 4: Persistent diarrhea with fever should be reported immediately to the health care provider.
Rationale 5: Some antibiotics cause nausea, especially when taken on an empty stomach. There is no need to report this immediately to a health care provider unless the client is unable to take the antibiotic.
Global Rationale: Ampicillin may decrease the effectiveness of oral contraceptives. Because food decreases its absorption, ampicillin should be taken on an empty stomach. Diarrhea is a common occurrence when taking ampicillin, but if the diarrhea is persistent and fever continues the health care provider should be consulted.
