A client's last menstrual period was April 11. Using Naegele's rule, her estimated date of birth (EDB) would be:

February 24

January 18

January 25

February 18

Answer and Explanation

The Correct Answer is B

Choice A Reason: This is incorrect because it is too early. Naegele's rule is a formula that estimates the date of birth by adding one year, subtracting three months, and adding seven days to the date of the last menstrual period. Applying this rule to April 11 gives February 18, not February 24.

Choice B Reason: This choice is correct because applying Naegele’s rule to the provided menstrual date (add seven days to the LMP, then subtract three months) produces the expected estimated delivery timeframe. The method yields the appropriate calendar month and day consistent with a full-term pregnancy calculation.

Choice C Reason: This is incorrect because it is too early. Naegele's rule gives February 18, not January 25.

Choice D Reason: This option is incorrect because it places the estimated delivery about one month later than the correct result. It appears to come from adding months without the proper day adjustment or from misapplying Naegele’s rule, resulting in a date that is too far into February.

Correct Answer is C

Explanation

Choice A Reason: This is incorrect because it adds 10 months and 7 days to the last menstrual period, which is not Nägele's rule.

Choice B Reason: This is incorrect because it adds 9 months and 7 days to the last menstrual period, which is not Nägele's rule.

Choice C Reason: This is correct because it follows Nägele's rule, which is to subtract 3 months and add 7 days to the last menstrual period.

Choice D Reason: This is incorrect because it subtracts 4 months and adds 7 days to the last menstrual period, which is not Nägele's rule.

Choice E Reason: This is incorrect because it subtracts 4 months and adds 17 days to the last menstrual period, which is not Nägele's rule.

A. It is primarily transmitted through mosquitoes. B. It is primarily transmitted through accidental puncture wounds. C. It is primarily transmitted through sexual contact. D. It is primarily transmitted through respiratory droplets.

Correct Answer is C

Explanation

Choice A Reason: This is incorrect because mosquitoes do not transmit HIV. HIV is a virus that infects human cells and cannot survive in insects. Mosquitoes do not inject blood from one person to another when they bite, but only saliva that contains anticoagulants and enzymes.

Choice B Reason: This is incorrect because accidental puncture wounds are not a common mode of HIV transmission. HIV can be transmitted through exposure to infected blood or body fluids, such as through needle sharing, blood transfusion, or occupational injury. However, these cases are rare and can be prevented by using sterile equipment, screening blood products, and following universal precautions.

Choice C Reason: This is correct because sexual contact is the most common mode of HIV transmission. HIV can be transmitted through unprotected vaginal, anal, or oral sex with an infected person, as these activities can involve contact with infected blood, semen, vaginal fluid, or pre-ejaculate.

Choice D Reason: This is incorrect because respiratory droplets do not transmit HIV. HIV is not an airborne virus and cannot be spread by coughing, sneezing, or breathing. HIV cannot be transmitted by casual contact, such as hugging, kissing, or sharing utensils.
