The nurse is teaching parents how to care for their son’s circumcision site after discharge from hospital using petroleum jelly and gauze dressing method.

Which statement by parents indicates that they need further instruction?

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

The correct answer is choice A. Glycogen.Preterm newborns have limited stores of glycogen, which is a substance made from glucose that is stored in the liver and muscle cells to be used later for energy.When blood glucose levels are low, the hormone glucagon signals the cells to convert glycogen back into glucose and release it into the bloodstream.However, preterm newborns have a reduced ability to produce glucagon and to use gluconeogenesis, which is the process of making new glucose from other sources.Therefore, they are at risk of hypoglycemia, which is a condition where blood glucose levels are too low to support normal brain function.

Choice B is wrong because glucose is the sugar that travels through the blood to fuel the cells, not a substance that is stored for later use.

Choice C is wrong because insulin is a hormone that helps cells absorb glucose from the blood, not a substance that is stored for later use.

Choice D is wrong because glucagon is a hormone that triggers the release of glucose from the liver and muscle cells, not a substance that is stored for later use.
