A nurse in a woman's health clinic is obtaining a health history from a client.
Which of the following findings should the nurse identify as increasing the client's risk for developing pelvic inflammatory disease (PID)?

Choice A rationale

Rapid plasma regain is not a standard laboratory test associated with hyperemesis gravidarum. Hyperemesis gravidarum is characterized by severe nausea and vomiting leading to dehydration and electrolyte imbalances.

Choice B rationale

A urine culture is used to detect urinary tract infections, which are not a primary concern in hyperemesis gravidarum unless specifically indicated by symptoms of a UTI.

Choice C rationale

Prothrombin time (PT) and other coagulation studies assess blood clotting. While severe dehydration and malnutrition from hyperemesis gravidarum could theoretically affect coagulation, it is not a routine initial test to anticipate.

Choice D rationale

Urine ketones are a key laboratory finding in hyperemesis gravidarum. Due to persistent vomiting and inadequate oral intake, the body starts to break down fat for energy, leading to ketonuria. The presence of ketones in the urine indicates starvation and the need for intravenous fluids and nutritional support.

Choice A rationale: Weight loss

Weight loss during pregnancy, especially in the second trimester, is unexpected unless there is a medical condition such as hyperemesis gravidarum or other nutritional deficiencies. While mild weight fluctuations can occur, a consistent loss of weight rather than gradual gain suggests inadequate caloric intake due to persistent vomiting and dehydration.

Choice B rationale: Breast tenderness

Breast tenderness is a common and expected physiological change during pregnancy due to hormonal fluctuations, particularly increased estrogen and progesterone levels. It is not considered abnormal or unexpected at this stage of pregnancy.

Choice C rationale: Heart rate

A heart rate of 116/min is unexpected, as it is above the normal range for adults (typically 60–100/min). Pregnancy can cause a mild increase in heart rate, but tachycardia above 110/min may indicate dehydration, anemia, or electrolyte imbalance, all of which can stem from excessive vomiting and fluid loss.

Choice D rationale: Vomiting

While occasional nausea and vomiting (morning sickness) can be expected in early pregnancy, persistent vomiting up to eight times daily and symptoms of dehydration (dry mucosa, poor skin turgor, positive ketones in urine) raise concern for hyperemesis gravidarum, a more severe form of pregnancy-related nausea and vomiting.

Choice E rationale: Nasal congestion

Nasal congestion is common during pregnancy due to increased blood volume and vascular changes affecting the nasal mucosa. It is not unexpected and does not indicate a complication.

Choice F rationale: Respiratory rate

A respiratory rate of 20/min falls within the normal range for adults (typically 12–20/min), making it an expected finding.
