A nurse at a clinic is counseling a client who has a positive pregnancy test. The first day of the client's last menstrual period was November 9. Use Nägele's rule to calculate the estimated date of delivery.
(Use the MMDD format with four numerals and no spaces or punctuation.)
The Correct Answer is ["0816"]
To calculate the estimated date of delivery using Nägele's rule, follow these steps:
-Add 7 days to the first day of the last menstrual period. In this case, November 9 + 7 days = November 16.
- Subtract 3 months from the month of the last menstrual period. In this case, November - 3 months = August.
The estimated date of delivery is August 16
The rationale for this rule assumes that the average menstrual cycle is 28 days long and that ovulation occurs on day 14 of the cycle. Therefore, adding 7 days to the first day of the last menstrual period approximates the date of conception. Subtracting 3 months from the month of the last menstrual period adjusts for the difference between the lunar calendar (13 months) and the Gregorian calendar (12 months).

Correct Answer is B
Explanation
Choice A rationale:
Using a disposable adhesive probe when measuring the client's SaO2 is not an intervention that can reduce the exposure of the client to latex, because adhesive probes may contain latex and cause skin reactions. A better option would be to use a non-adhesive probe or a probe cover that is latex-free.
Choice B rationale:
Rationale: Latex sensitivity or allergy can lead to adverse reactions when exposed to latex- containing products, such as blood pressure cuffs. Wrapping the blood pressure cuff in a stockinette helps minimize direct contact between the cuff and the client's skin.
Choice C rationale:
Silicone products are usually considered safe for individuals with latex sensitivity because silicone is a different material. Silicone products are generally safe for clients who are sensitive to latex, unless they have a separate allergy to silicone.
Choice D rationale:
Cleaning vial stoppers for 15 seconds before using them to withdraw-medications for the client is not an intervention that can reduce the exposure of the client to latex, because vial stoppers may be made of latex or rubber and cleaning them does not remove the allergen. A better option would be to use vials that have latex-free stoppers or to avoid puncturing the stoppers with needles.
Correct Answer is D
Explanation
Choice A rationale:
Radiation therapy is not typically the primary method of treatment for melanoma. Surgical excision and other therapies are often utilized.
Choice B rationale:
Metastasis in melanoma generally occurs from the outer layers of the skin to deeper levels and eventually to other parts of the body.
Choice C rationale:
Specific genetic mutations, such as mutations in the BRAF gene, are associated with an increased risk of developing melanoma.
Choice D rationale: Melanoma is a highly metastatic form of skin cancer that can spread quickly to other parts of the body. Early diagnosis and treatment are crucial to improve outcomes.
