Correct Answer: B

Rationale: For a client with a BMI of 26.5 (overweight), the recommended weight gain during pregnancy is 15 to 25 pounds. This range helps promote a healthy pregnancy outcome and reduces the risk of complications associated with excessive weight gain. Option A suggests a lower weight gain range, which may not be adequate for a client with a BMI of 26.5. Option C indicates a higher weight gain range, which could lead to complications for an overweight individual. Option D provides a general guideline for weight gain without considering the client's BMI, which is not personalized advice. Therefore, the most appropriate response is option B, offering a suitable weight gain recommendation for the client's BMI to support a healthy pregnancy journey.

Correct Answer: D

Rationale: Variable decelerations can indicate umbilical cord compression, which is a concern that may arise due to the umbilical cord being compressed during labor. This compression can lead to reduced blood flow and oxygen delivery to the fetus, necessitating close monitoring and potentially interventions to alleviate the pressure on the cord. Early decelerations are typically benign and mirror the contractions, indicating fetal head compression. Accelerations are reassuring patterns that show a healthy response to fetal movement. Late decelerations are concerning as they suggest uteroplacental insufficiency, indicating potential oxygen deprivation to the fetus.

Correct Answer: B

Rationale: When measuring a newborn's chest circumference, the appropriate anatomical landmark to use is the nipple line. This point is consistent and allows for accurate and standardized measurements across all newborn assessments. The sternal notch is not typically used for chest circumference measurements in newborns. The xiphoid process is located at the lower end of the sternum and is not an appropriate landmark for chest circumference measurement. The fifth intercostal space is typically used for locating the point of maximal impulse (PMI) during cardiac assessments, not for measuring chest circumference.

Correct Answer: D

Rationale: The correct sequence of maternal changes during pregnancy is as follows: Amenorrhea (absence of menstrual periods), Goodell's sign (softening of the cervix), Quickening (first fetal movements felt by the mother), and Lightening (baby descending into the pelvis). These changes occur at different stages of pregnancy and are important indicators of fetal development and maternal adaptation. Choice A is correct as it is the initial change indicating possible pregnancy. Choices B, C, and D follow in the correct order of occurrence during pregnancy. Choices B, C, and D are incorrect as they do not follow the correct sequence of maternal changes.

Correct Answer: D

Rationale: Deep tendon reflexes of +1 are inconsistent with preeclampsia. Preeclampsia typically presents with hyperreflexia, not diminished reflexes. Diminished reflexes may indicate other neurological conditions, thus making this finding inconsistent with preeclampsia. Choices A, B, and C are consistent with preeclampsia. Pitting sacral edema, protein in the urine, and elevated blood pressure are common findings in preeclampsia due to fluid retention, kidney involvement, and hypertension associated with the condition.
