A nurse is completing a health history and assessment for a client who reports they are pregnant.
Which of the following findings is a presumptive sign of pregnancy?

Choice A rationale

During labor, the body experiences physiological stress and an inflammatory response, leading to an increase in white blood cell count. This leukocytosis is a normal physiological adaptation to the physical demands of labor and tissue remodeling, not a decrease. A normal WBC count is typically 4,500-11,000 cells/µL, and it can rise to 15,000-20,000 cells/µL during labor.

Choice B rationale

Labor is an energy-intensive process that increases metabolic demands, leading to greater glucose utilization by uterine muscles and other tissues. This increased consumption of glucose can result in a decrease in blood glucose levels as the body expends energy to fuel contractions and other physiological activities. A normal blood glucose range is 70-100 mg/dL.

Choice C rationale

The pain and physiological stress of labor typically cause an increase in respiratory rate, not a decrease. The body tries to compensate for the increased metabolic demand and oxygen consumption by increasing ventilation. A decrease in respiratory rate would be an unexpected and potentially concerning finding, indicating respiratory depression. A normal respiratory rate is 12-20 breaths per minute.

Choice D rationale

While slight fluctuations can occur, a significant decrease in temperature is not an expected finding during labor. The metabolic activity and physical exertion of labor can slightly elevate body temperature, or it may remain stable. A decrease in temperature could indicate hypothermia or a systemic issue, which is not a normal physiological response to labor. A normal temperature is 36.5-37.5°C.

Choice A rationale

A client with an indwelling urinary catheter is at increased risk for falls due to several factors. The catheter tubing can create a tripping hazard, and the associated bag can restrict mobility. Furthermore, the presence of a catheter can lead to postural hypotension upon ambulation due to prolonged bedrest or fluid shifts, impairing balance and increasing fall risk.

Choice B rationale

A second-degree perineal laceration causes localized pain and discomfort, potentially leading to a cautious gait. While this can affect mobility, it does not inherently present the same level of tripping hazard or systemic physiological changes like orthostatic hypotension that are associated with an indwelling catheter, making the fall risk comparatively lower.

Choice C rationale

Saturating a perineal pad every 5 to 6 hours indicates a normal lochial flow. Excessive bleeding (saturating a pad in less than an hour) would be a significant risk factor for hypovolemia and subsequent orthostatic hypotension, thus increasing fall risk. Normal flow, however, does not directly contribute to an increased fall risk.

Choice D rationale

Breast engorgement causes discomfort and fullness in the breasts, which can limit arm movement and potentially interfere with comfortable positioning. While uncomfortable, breast engorgement itself does not typically lead to systemic physiological changes like orthostatic hypotension or create physical impediments that directly increase the risk of a fall.
