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

Answer and Explanation

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

The correct answer is choice C. Dry, cracked skin.

Choice A rationale:

Increased subcutaneous fat is more commonly seen in full-term infants, but post-term infants (born after 42 weeks) often have decreased subcutaneous fat due to the aging placenta’s reduced efficiency in nutrient delivery.

Choice B rationale:

Scant scalp hair is typically seen in preterm infants. Post-term infants usually have more developed features, including more scalp hair.

Choice C rationale:

Dry, cracked skin is a common finding in post-term infants because the protective vernix caseosa, which covers the skin in utero, has often been shed by this stage. The prolonged exposure to amniotic fluid can lead to skin that appears dry, cracked, and peeling.

Choice D rationale:

Copious vernix is usually seen in preterm infants. By 42.5 weeks, most of the vernix has been absorbed or shed, leading to the dry skin observed in post-term infants.

A. Place the client in the Trendelenburg position. B. Assess maternal blood glucose. C. Discontinue the medication infusion. D. Prepare for an emergency cesarean birth.

Correct Answer is C

Explanation

Choice a reason:
Placing the client in the Trendelenburg position, which involves lying on the back with the feet higher than the head, is not indicated for the symptoms presented. This position is typically used to treat hypotension or improve venous return to the heart, not for respiratory depression or absent deep-tendon reflexes, which are signs of magnesium sulfate toxicity.

Choice b reason:
Assessing maternal blood glucose is important in the overall care of a preeclamptic patient, especially if there is a concern for gestational diabetes. However, it is not the immediate action required when a patient exhibits signs of magnesium sulfate toxicity, such as a respiratory rate of 10/min and absent deep-tendon reflexes.

Choice c reason:
Discontinuing the medication infusion is the correct action. A respiratory rate of 10/min and absent deep-tendon reflexes are signs of magnesium sulfate toxicity. Immediate cessation of the drug is necessary to prevent further complications, such as respiratory depression or cardiac arrest. After stopping the infusion, the nurse should monitor the patient closely and prepare to administer calcium gluconate, the antidote for magnesium sulfate toxicity, if ordered by the physician.

Choice d reason:
Preparing for an emergency cesarean birth may be necessary if the fetus is in distress or if there are other obstetric indications. However, the information provided does not indicate fetal distress or an immediate need for delivery. The priority is addressing the signs of magnesium sulfate toxicity in the mother.
