Evaluate these sample clicker questions With a partner, rate each question on a scale of 1 (poor) to 5 (fantastic). Use the reflection points (CONTENT – DIFFICULTY – WRONG ANSWERS – CLARITY – CONNECTION TO EXPECTATION) to assess as many of them as you have time for. 6. 1. Your sister in law calls to say that she’s having twins. Which of the following is the most likely? (Assume she’s having fraternal, not identical, twins) a. Twin boys b. Twin girls c. One girl and one boy d. All are equally likely 2. When you lose 10 pounds, where does most of the weight go? a. Out of the body in secretions b. Out of the body in air you exhale c. The body uses it up as energy d. Half out of the body in secretions and half used up as energy 3. A patient has been identified as having a very virulent bacterial infection that is spread through close physical contact. To decrease the chance of spreading this organism, which infection control precautions should be implemented? a. Airborne precautions b. Droplet precautions c. Contact precautions d. Protective isolation 4. Why do we still get sick if we have a sophisticated immune system to take care of infection? a. It takes time for the immune system to respond b. Our immune system cannot recognize all foreign invaders c. Microorganisms depress the immune system d. Immune system can only respond to bacterial infection 5. Select the factor(s) that would result in a decrease in blood pressure a. Increased arterial diameter b. Decreased stroke volume c. Decreased blood viscosity d. Increased parasympathetic stimulation e. All of the above 7. Indirect calorimetry measures what variable to determine energy output? a. Carbon dioxide b. ATP c. Heat d. Oxygen e. Nitrogen 8. If a person has many copies of a particular protein whose structure is changed from normal, where did the mutation causing this change most likely originate? a. In the DNA sequence of the gene b. In the mRNA sequence c. In the amino acid sequence d. In the protein 9. Francis Crick and colleagues did a clever experiment to prove that the unit read into an amino acid, now called a “codon”, was 3 bases. What could we do to prove that a codon is 3 bases? a. Add a nucleotide to a sequence b. Remove a nucleotide from a sequence c. Add 3 different nucleotides to a sequence d. All of the above 10. A mutation in the gene that causes polydactyl (extra fingers or toes) converts a normal codon in the middle of the gene to a stop codon. This type of mutation will lead to: a. an early stop in translation of the RNA into amino acids (shorter protein) b. an early stop in transcription of the DNA into RNA (shorter transcript) c. both a and b d. neither a nor b
