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
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 A
Explanation
Choice A Reason: Trisomy numeric abnormality. Down syndrome is a genetic disorder that occurs when a person has three copies of chromosome 21 instead of two. This extra chromosome causes various physical and mental features that vary from person to person. Down syndrome is also called trisomy 21 because it involves three copies of chromosome 21.
Choice B Reason: Multifactorial inheritance is incorrect because it refers to a type of genetic disorder that results from the interaction of multiple genes and environmental factors. Examples of multifactorial disorders include cleft lip or palate, neural tube defects, diabetes, hypertension, and some types of cancer.
Choice C Reason: X-linked recessive inheritance is incorrect because it refers to a type of genetic disorder that affects males more than females because it is caused by a mutation on the X chromosome. Females have two X chromosomes, so they can be carriers or affected depending on whether they inherit one or two copies of the mutated gene. Males have one X chromosome and one Y chromosome, so they are always affected if they inherit the mutated gene from their mother. Examples of X-linked recessive disorders include hemophilia, color blindness, and Duchenne muscular dystrophy.
Choice D Reason: Chromosomal deletion is incorrect because it refers to a type of genetic disorder that occurs when a part of a chromosome is missing or deleted. This can cause various physical and mental problems depending on the size and location of the deletion. Examples of chromosomal deletion
Correct Answer is ["2"]
Explanation
The correct answer is 2 mL. To calculate the volume to administer, the nurse should use the following formula:
Volume (mL) = Dose (units) / Concentration (units/mL)
Plugging in the given values, we get:
Volume (mL) = 1,200,000 units / 600,000 units/mL
Volume (mL) = 2 mL
Rounding to the nearest whole number, we get 2 mL.
