Question 1 of 5
Which hormone is responsible for amenorrhea in the pregnant woman?
Correct Answer: A
Rationale: Correct! Progesterone is the hormone responsible for amenorrhea in pregnant women. Progesterone plays a crucial role in maintaining the uterine lining for implantation and supporting early pregnancy. High levels of progesterone during pregnancy suppress the normal menstrual cycle, leading to amenorrhea. Estrogen, FSH, and hCG do not directly cause amenorrhea in pregnant women. Estrogen is involved in the development of female secondary sexual characteristics, FSH is involved in the growth and maturation of ovarian follicles, and hCG is produced by the placenta to support the production of progesterone during pregnancy.
Question 2 of 5
When planning care for a client taking Heparin, which nursing diagnosis should the nurse address first?
Correct Answer: B
Rationale: The correct answer is 'Risk for injury related to active loss of blood from the vascular space.' When a client is taking Heparin, the primary concern is the risk of bleeding due to its anticoagulant properties. Monitoring for signs of active blood loss is crucial to prevent complications like hemorrhage. While ineffective tissue perfusion, deficient knowledge, and impaired skin integrity are important, they are secondary to the immediate risk of bleeding in clients taking anticoagulants like Heparin.
Question 3 of 5
The nurse is caring for a client admitted with Class III/IV Pulmonary Hypertension. The nurse explains to the client that Lanoxin is being administered to the client in order to:
Correct Answer: B
Rationale: The correct answer is to improve right ventricular function. Lanoxin, also known as digoxin, is a cardiac glycoside that works by slowing the heart rate and increasing myocardial contractility, especially in the ventricles. This action helps improve the efficiency of the heart's pumping function, particularly the right ventricle in conditions like pulmonary hypertension.
Choice A, managing peripheral edema, is not directly related to Lanoxin's mechanism of action.
Choice C, increasing pulmonary pressure, is incorrect as Lanoxin is not used to increase pressure in the pulmonary circulation.
Choice D, constricting the pulmonary vessels, is incorrect as Lanoxin does not cause vasoconstriction in the pulmonary vessels but rather acts on the heart's contractility.
Question 4 of 5
A healthcare provider is screening patients for various vaccines. Which of the following vaccines is contraindicated during pregnancy?
Correct Answer: C
Rationale: The correct answer is Mumps. The Mumps vaccine, along with the Rubella vaccine, is contraindicated during pregnancy due to the theoretical risk of affecting the developing fetus. Diphtheria, Hepatitis B, and Tetanus vaccines are considered safe during pregnancy and are often recommended to protect both the pregnant individual and the developing fetus.
Therefore, choices A, B, and D are incorrect.
Question 5 of 5
A client has been receiving cyanocobalamin (B12) injections for the past 6 weeks. Which laboratory finding indicates that the medication is having the desired effect?
Correct Answer: D
Rationale: Cyanocobalamin is a B12 medication used for pernicious anemia. A reticulocyte count of 1% indicates the desired effect of the medication, as reticulocytes are immature red blood cells that increase in response to B12 therapy, improving anemia. Neutrophils, basophils, and monocytes are white blood cells and are not directly influenced by B12 injections, making them incorrect choices.
