The nurse is assessing the 6 stages of cardinal gaze. This test assesses:
Cranial nerves III, IV, and X for eye muscle strength.
Cranial nerves III, IV, and VI for ocular motor movements.
Cranial nerves IV, V and VII for visual accuracy.
Cranial nerve II for visual acuity.
The Correct Answer is B
The nurse is assessing the 6 stages of the cardinal gaze to evaluate the function of the cranial nerves III, IV, and VI for ocular motor movements, which control eye movement and positioning.
Cranial nerve III controls the superior rectus, inferior rectus, and medial rectus muscles, which move the eye up, down, and inward, respectively. Cranial nerve IV controls the superior oblique muscle, which moves the eye downward and laterally. Cranial nerve VI controls the lateral rectus muscle, which moves the eye outward.
Therefore, the nurse will observe the patient's ability to move their eyes smoothly in each of the six cardinal positions of gaze and note any abnormalities that may indicate dysfunction of these cranial nerves. This test is used to diagnose conditions such as strabismus, nystagmus, and palsy of the ocular motor nerves.
Cranial nerve II, on the other hand, is responsible for visual acuity, not eye movement, and is tested separately using a visual acuity chart or other vision tests.

Correct Answer is C
Explanation
Level of consciousness (LOC) is a key indicator of neurological function and is typically assessed by observing a patient’s wakefulness, awareness, and responsiveness to stimuli.
Correct Answer is A
Explanation
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.
