A nurse is caring for a client who is 6 hours postpartum. The client is Rh-negative and her newborn is Rh-positive. The client asks why an indirect Coombs test was ordered by the provider. Which of the following is an appropriate response by the nurse?

Choice a reason:
A fundus that is palpable to the right of the midline can indicate a distended bladder. After childbirth, the bladder can become distended due to decreased sensitivity, which may be caused by trauma during delivery or the effects of anesthesia. A distended bladder can push the uterus to the side and prevent it from contracting properly, leading to increased bleeding. It's important for the nurse to encourage the client to void to relieve bladder distension and allow the uterus to contract effectively.

Choice b reason:
Less than 2.5 cm of rubra lochia on the perineal pad does not necessarily indicate bladder distension. Lochia rubra is the normal discharge of blood, mucus, and tissue from the uterus after childbirth, and its amount can vary widely among individuals. While heavy lochia can be a sign of postpartum hemorrhage, it is not directly related to bladder distension.

Choice c reason:
Increased thirst in a postpartum client is not a direct indicator of bladder distension. Thirst can be influenced by various factors, including dehydration from labor, breastfeeding, or hormonal changes. While it's important for a postpartum client to stay hydrated, increased thirst alone does not suggest a distended bladder.

Choice d reason:
Frequent uterine contractions reported by the client are not a sign of bladder distension. These contractions, known as afterpains, are normal and occur as the uterus contracts to return to its pre-pregnancy size. While uncomfortable, they are a sign of the uterus working to expel blood and tissue and do not indicate bladder issues.

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.
