When describing the menstrual cycle to a group of young women, the nurse explains that estrogen levels are highest during which phase of the endometrial cycle?

Menstrual

Ischemic

Secretory

Proliferative

Answer and Explanation

The Correct Answer is D

Choice A: Menstrual is not the correct answer because it is the phase when estrogen levels are lowest. The menstrual phase occurs when the endometrium (the lining of the uterus) is shed along with blood and mucus through the vagina.

Choice B: Ischemic is not the correct answer because it is the phase when estrogen levels are decreasing. The ischemic phase occurs when the blood supply to the endometrium is reduced due to vasoconstriction (narrowing of blood vessels). This phase prepares the endometrium for shedding if fertilization does not occur.

Choice C: Secretory is not the correct answer because it is the phase when progesterone levels are highest. The secretory phase occurs when the endometrium becomes thick and spongy due to increased secretion of mucus and glycogen (a form of sugar). This phase provides a suitable environment for implantation if fertilization occurs.

Choice D: Proliferative is the correct answer because it is the phase when estrogen levels are highest. The proliferative phase occurs when the endometrium regenerates and grows due to increased stimulation by estrogen. This phase prepares the endometrium for implantation if fertilization occurs.

Correct Answer is ["20"]

Explanation

- To find out how many gtt/min to set for a manual IV infusion, we need to use this formula: gtt/min = (mL/hr x drop factor) / 60

- In this formula, mL/hr is the rate of infusion in milliliters per hour, drop factor is the number of drops per milliliter for a specific IV tubing, and 60 is the number of minutes in an hour.

- We plug in the given values into this formula: gtt/min = (120 mL/hr x 10 gtt/mL) / 60

- We simplify and solve this equation: gtt/min = (1200 gtt/hr) / 60

- We divide both sides by 60: gtt/min = 20 gtt/hr

- We round off to the nearest whole number: gtt/min = **20**

- We add a leading zero if needed: gtt/min = **20**

- We do not add a trailing zero: gtt/min = **20**

A. Vomiting B. Fatigue C. Hair loss D. Myelosuppression

Correct Answer is D

Explanation

Choice A: Vomiting is not the most serious side effect because it is a common and manageable side effect of chemotherapy. Vomiting is a reflex action that expels the contents of the stomach through the mouth. It can be caused by various factors such as nausea, motion sickness, or infection. It can also be caused by chemotherapy, which can irritate the lining of the stomach or trigger the vomiting center in the brain. Vomiting can be prevented or treated with antiemetic drugs, hydration, and dietary changes.

Choice B: Fatigue is not the most serious side effect because it is a common and manageable side effect of chemotherapy. Fatigue is a condition that causes extreme tiredness or exhaustion that is not relieved by rest or sleep. It can be caused by various factors such as anemia, inflammation, or pain. It can also be caused by chemotherapy, which can damage healthy cells and tissues and affect the body's energy production. Fatigue can be managed with exercise, nutrition, and stress reduction.

Choice C: Hair loss is not the most serious side effect because it is a common and temporary side effect of chemotherapy. Hair loss is a condition that causes hair to fall out from the scalp or other parts of the body. It can be caused by various factors such as genetics, hormones, or infection. It can also be caused by chemotherapy, which can target rapidly dividing cells such as hair follicles and prevent hair growth. Hair loss usually occurs within two to four weeks after starting chemotherapy and reverses within six months after stopping chemotherapy.

Choice D: Myelosuppression is the most serious side effect because it is a rare and life-threatening side effect of chemotherapy. Myelosuppression is a condition that causes a decrease in the production of blood cells in the bone marrow. It can lead to anemia (low red blood cells), neutropenia (low white blood cells), and thrombocytopenia (low platelets), which can cause symptoms such as weakness, infection, and bleeding. It can also be caused by chemotherapy, which can target rapidly dividing cells such as bone marrow cells and impair blood cell formation. Myelosuppression requires close monitoring and treatment with blood transfusions, growth factors, or antibiotics.
