A nurse is preparing to administer hepatitis B vaccine to a newborn whose mother is hepatitis B surface antigen negative (HBsAg-).

Which of the following actions should the nurse take?

The correct answer is choice A, B, C, D and E.All of these are possible modes of transmission for hepatitis B virus (HBV), which is a viral infection that attacks the liver and can cause both acute and chronic disease.The virus is most commonly transmitted from mother to child during birth and delivery, as well as through contact with blood or other body fluids during sex with an infected partner, unsafe injections or exposures to sharp instruments.

Choice A is correct because unprotected sexual contact can expose a person to the blood, semen, or vaginal fluids of an infected partner.

Choice B is correct because sharing drugs, needles, or “works” when using drugs can expose a person to the blood of an infected person.

Choice C is correct because poor infection control practices in medical settings can expose a person to contaminated needles or syringes or sharp objects that have been used on an infected person.

Choice D is correct because sharing of blood sugar (diabetes) testing equipment can expose a person to the blood of an infected person.

Choice E is correct because needle sticks or sharps exposures on the job can expose a person to the blood of an infected

The correct answer is choice B. Lactic acidosis.

Lamivudine (Epivir) is a nucleoside reverse transcriptase inhibitor (NRTI) used to treat chronic hepatitis B infection and HIV infection.

One of the rare but serious adverse effects of lamivudine is lactic acidosis, which is a condition where the blood becomes too acidic due to the accumulation of lactate.Lactic acidosis can cause symptoms such as nausea, vomiting, abdominal pain, muscle weakness, rapid breathing, and low blood pressure.

Choice A is wrong because pancreatitis is not a common side effect of lamivudine.

Pancreatitis is an inflammation of the pancreas that can cause severe abdominal pain, nausea, vomiting, and fever.Pancreatitis is more likely to occur with other NRTIs such as didanosine (Videx) or stavudine (Zerit).

Choice C is wrong because hypothyroidism is not a common side effect of lamivudine.

Hypothyroidism is a condition where the thyroid gland does not produce enough thyroid hormones, which regulate the metabolism and energy levels of the body.

Hypothyroidism can cause symptoms such as fatigue, weight gain, cold intolerance, dry skin, hair loss, and depression.

Hypothyroidism is more likely to occur with other drugs that interfere with thyroid function such as amiodarone (Cordarone) or lithium
