The nurse caring for a woman hospitalized for hyperemesis gravidarum should expect that initial treatment will involve:

Choice A reason: Eating three larger meals a day is not recommended for hyperemesis gravidarum, as it may increase the nausea and vomiting. Instead, the nurse should advise the woman to eat small, frequent meals throughout the day.

Choice B reason: Ice cream may stay down better than other foods, as it is cold, bland, and soothing. The nurse should encourage the woman to try foods that are appealing to her and avoid foods that trigger nausea.

Choice C reason: Eating what sounds good to the woman even if her meals are not well-balanced is acceptable for hyperemesis gravidarum, as the priority is to maintain hydration and nutrition. The nurse should reassure the woman that she can resume a balanced diet once her symptoms improve.

Choice D reason: Avoiding ginger tea or sweet drinks is not necessary for hyperemesis gravidarum, as some women may find them helpful in reducing nausea. The nurse should suggest the woman to experiment with different beverages and see what works for her.

Choice E reason: Eating a high-protein snack at bedtime is beneficial for hyperemesis gravidarum, as it can prevent low blood sugar levels and morning sickness. The nurse should recommend the woman to have a protein-rich food, such as cheese, yogurt, nuts, or eggs, before going to bed.

Choice A reason: This is incorrect because venipuncture for blood work should be avoided on the affected arm. The mastectomy may have involved the removal of lymph nodes, which can impair the lymphatic drainage and increase the risk of lymphedema (swelling) in the arm. Venipuncture can cause further damage or infection to the arm.

Choice B reason: This is correct because the BP cuff should not be applied to the affected arm. The BP cuff can exert pressure on the arm and interfere with the blood and lymph flow. This can also increase the risk of lymphedema or pain in the arm.

Choice C reason: This is incorrect because the affected arm should not be held down close to the woman's side. The woman should be encouraged to elevate the arm above the level of the heart and perform gentle exercises to promote circulation and prevent stiffness. The arm should not be immobilized or restricted.

Choice D reason: This is incorrect because the affected arm should not be used for IV therapy. IV therapy can introduce fluids or medications into the arm that can affect the blood and lymph flow. It can also cause irritation or infection to the arm.
