A nurse is instructing a female client on how to check her basal body temperature to determine if she is ovulating. The nurse should instruct the client to check her temperature at which of the following times?
1 hour following intercourse
Every morning before arising
Before going to bed every night
On days 13 to 17 of her menstrual cycle
The Correct Answer is B
Choice A reason:
Checking basal body temperature 1 hour following intercourse is not recommended as a method to determine ovulation. Intercourse and physical activity can increase body temperature, which may lead to inaccurate readings. Basal body temperature should be measured after a period of rest, not after physical activity.
Choice B reason:
The basal body temperature method involves measuring the body's at-rest temperature to identify slight changes that occur around the time of ovulation. It is most accurate when taken every morning before getting out of bed, after at least 3 hours of uninterrupted sleep, and before any physical activity, including eating or drinking. A slight increase in basal body temperature typically occurs after ovulation and remains elevated until the next menstrual period. This method requires consistency and precise timing to be effective.
Choice C reason:
Measuring basal body temperature before going to bed every night is not an effective way to track ovulation. The body's temperature fluctuates throughout the day due to various factors, including activity levels, meals, and external temperatures. Therefore, nighttime measurements would not provide the consistent, resting temperature needed to accurately detect ovulation.
Choice D reason:
While it is true that ovulation typically occurs around the middle of the menstrual cycle, which for many women is between days 13 to 17, limiting temperature checks to these days only may miss the initial rise in temperature that indicates ovulation. Ovulation can vary from cycle to cycle, and it is important to measure basal body temperature daily to detect the pattern over time.

Correct Answer is C
Explanation
Choice a reason:
A male condom is a barrier method of contraception that is typically easy to use and accessible. It has the added benefit of providing protection against sexually transmitted infections (STIs). However, its effectiveness can be compromised by improper use or breakage. With typical use, male condoms are about 85% effective.
Choice b reason:
A diaphragm with spermicide is another barrier method that can be used to prevent pregnancy. The diaphragm covers the cervix and the spermicide kills or immobilizes sperm. The effectiveness of a diaphragm with spermicide is generally lower than some other methods, with typical use effectiveness around 88%.
Choice c reason:
An intrauterine device (IUD) is a small device inserted into the uterus by a healthcare provider. IUDs come in two types: hormonal and copper. Both types are highly effective, with over 99% effectiveness. They are long-acting, reversible, and do not require daily attention, which contributes to their reliability.
Choice d reason:
An oral contraceptive, also known as the birth control pill, is a popular method of contraception that requires the user to take a pill at the same time every day. The effectiveness of the pill can be high, but because it relies on user adherence, its typical use effectiveness is around 91%.
Correct Answer is B
Explanation
Choice a reason:
Mongolian spots are a type of pigmented birthmark commonly found in newborns, often appearing as blue or grayish areas on the skin. They are not related to swelling and do not result from vacuum-assisted deliveries. Mongolian spots are usually located on the buttocks or lower back and are not associated with the type of swelling described by the mother.
Choice b reason:
Caput succedaneum is a condition where the newborn's scalp swells due to pressure during delivery. It is characterized by a soft, spongy mass that crosses suture lines and is most apparent on the part of the skull that was first to enter the birth canal. This condition is common in vacuum-assisted deliveries and is the correct explanation for the swelling observed on the newborn's head.
Choice c reason:
Erythema toxicum is a common and benign skin condition in newborns, presenting as red patches or small, fluid-filled bumps. It is not related to the swelling described and does not result from vacuum-assisted deliveries. Erythema toxicum typically resolves on its own and does not cause the type of swelling that crosses suture lines.
Choice d reason:
Cephalohematoma is a collection of blood between a newborn's scalp and the skull bone that results from ruptured blood vessels, which can be a result of birth trauma or pressure. However, it is typically confined to one area and does not cross suture lines. Since the swelling described by the mother crosses the suture lines, cephalohematoma is less likely to be the correct diagnosis.
