A nurse is reviewing the electronic medical record of a pregnant client who reports regular use of alcohol.
Which of the following findings should the nurse identify as an indication the client may be at risk for polysubstance use disorder? (Select All that Apply)

Rationale for correct condition: Hyperemesis gravidarum is a severe form of nausea and vomiting during pregnancy, leading to dehydration, weight loss, and electrolyte imbalance. The client's significant weight loss of 2.8 kg (6.2 lb) in two weeks, increased nausea and vomiting, and decreased appetite are classic symptoms. The elevated BUN level suggests dehydration, which aligns with hyperemesis gravidarum. The absence of abdominal pain and the presence of facial pallor further support this condition.

Rationale for actions:

1. Initiate IV fluid therapy to rehydrate the client and correct electrolyte imbalances caused by excessive vomiting.
2. Administer ondansetron IV to control nausea and vomiting, improving the client's ability to tolerate oral intake.

Rationale for parameters:

1. Weight should be monitored to assess the effectiveness of interventions and ensure the client is regaining or maintaining a healthy weight.
2. Urine output indicates hydration status and kidney function, helping to evaluate the adequacy of fluid replacement.

Rationale for incorrect conditions:

• Cholecystitis: The client denies abdominal or epigastric pain, which is a key symptom of cholecystitis.
• Gestational diabetes mellitus: There is no mention of elevated blood glucose levels or other diabetic symptoms.
• Preeclampsia: The client's blood pressure is within normal range, and there are no signs of hypertension or proteinuria.

Choice A rationale

A rubella titer of 1: indicates the presence of antibodies against the rubella virus, but this does not confirm the absence of a current infection. The titer represents past exposure or vaccination rather than an active infection.

Choice B rationale

A rubella titer of 1: suggests immunity to the rubella virus, making vaccination unnecessary at this time. Vaccination is typically recommended for those without immunity to prevent future infection.

Choice C rationale

A titer of 1: indicates the presence of antibodies sufficient to confer immunity to the rubella virus. This level is generally considered protective, implying the client has either had the infection before or has been vaccinated.

Choice D rationale

A mild rubella infection would not typically be determined solely by the titer level. Clinical symptoms and further diagnostic tests are required to diagnose an active rubella infection accurately.
