The nurse is assessing the patient's lips and notes a bluish tinge. This finding would indicate that the patient may be experiencing which problem?

REM (Rapid Eye Movement) sleep is a stage of sleep that is part of the sleep cycle, which also includes non-REM (NREM) sleep. Dreaming occurs during REM sleep, and it usually composes about 20-25% of total sleep time in adults. NREM sleep, on the other hand, makes up the largest amount of total sleep time, typically about 75-80%. Both REM and NREM sleep are important for restorative sleep, but each plays a different role in physiological and cognitive functioning.

This is the medication that the nurse should expect to administer to the client who is receiving treatment for gestational diabetes mellitus. Gestational diabetes mellitus (GDM) is a condition that occurs when a pregnant woman has high blood sugar levels that are not controlled by diet and exercise alone. GDM can cause complications for the mother and the baby, such as preeclampsia, macrosomia, hypoglycemia, and birth trauma¹. The primary treatments for GDM are diet and increased exercise. However, some women may need medication to lower their blood sugar levels.

The most common medication used for GDM is insulin, which is a hormone that helps the body use glucose for energy. Insulin can be given by injection or by an insulin pump¹. However, some women may prefer oral medications over insulin injections. One of the oral medications that can be used for GDM is glyburide, which is a sulfonylurea drug that stimulates the pancreas to produce more insulin. Glyburide can lower blood sugar levels and reduce the need for insulin in some women with GDM²³. Glyburide is generally safe and effective for GDM, but it may cause side effects such as hypoglycemia, weight gain, nausea, and allergic reactions²⁴.

The other options are not correct because they are not medications used for gestational diabetes mellitus.

b) Levothyroxine
Levothyroxine is a synthetic form of thyroxine, which is a hormone produced by the thyroid gland. Levothyroxine is used to treat hypothyroidism, which is a condition that occurs when the thyroid gland does not produce enough thyroid hormones. Hypothyroidism can cause symptoms such as fatigue, weight gain,cold intolerance, and depression. Levothyroxine is not used to treat gestational diabetes mellitus.
c) Nifedipine
Nifedipine is a calcium channel blocker that relaxes the blood vessels and lowers blood pressure. Nifedipine is used to treat hypertension, angina, and preterm labor. Hypertension is a condition that occurs when the blood pressure is too high. Angina is a type of chest pain that occurs when the heart does not get enough oxygen. Preterm labor is a condition that occurs when the uterus contracts and dilates before 37 weeks of pregnancy. Nifedipine is not used to treat gestational diabetes mellitus.
d) Chlorpromazine
Chlorpromazine is an antipsychotic drug that blocks dopamine receptors in the brain. Chlorpromazine is used to treat schizophrenia, bipolar disorder, and nausea and vomiting. Schizophrenia is a mental disorder that causes distorted thoughts, hallucinations, and delusions. Bipolar disorder is a mental disorder that causes mood swings between mania and depression. Nausea and vomiting are symptoms that can be caused by various conditions or treatments. Chlorpromazine is not used to treat gestational diabetes mellitus.
