The answer is stabilizing selection.
<span>Sickle-cell anemia is a recessive disorder caused by the presence of two recessive alleles "s", so genotype is "ss". This disorder is characterized by sickle hemoglobin. In an area with malaria, heterozygous individuals "Ss" (with one dominant allele and one recessive allele) have an advantage. These individuals will have both normal and sickle hemoglobin. But pathogen that causes malaria affect only normal hemoglobin, so heterozygous individuals will have half of the hemoglobin resistant to the pathogen and those individuals are resistant to malaria.</span>
Stabilizing selection favors heterozygotes Ss, disruptive selection favors dominant (SS) and recessive (ss) homozygotes, while directional selection favors dominant (SS) or recessive (ss) homozygote. Since in this example, people with genotype Ss (heterozygotes) are in advantage, then this is an example of stabilizing selection.
Answer:
This tool is divided into three sections representing the principles in the Medication practice standard: authority, competence, and safety.
Explanation:
Rights of Medication Administration
1. Right patient
- Check the name of the order and the patient.
- Use 2 identifiers.
- Ask patient to identify himself/herself.
2. Right medication
- Check the medication label.
- Check the order.
3. Right dose
- Check the order.
- Confirm the appropriateness of the dose using a current drug reference.
4. Right route
- Again, check the order and appropriateness of the route ordered.
- Confirm that the patient can take or receive the medication by the ordered route.
5. Right time
- Check the frequency of the ordered medication.
- Double-check that you are giving the ordered dose at the correct time.
- Confirm when the last dose was given.
6. Right documentation
- Document administration AFTER giving the ordered medication.
- Chart the time, route, and any other specific information as necessary.
7. Right reason
- Confirm the rationale for the ordered medication. What is the patient’s history? Why is he/she taking this medication?
8. Right response
- Make sure that the drug led to the desired effect. If an antihypertensive was given, has his/her blood pressure improved?
- Does the patient verbalize improvement in depression while on an antidepressant?
