A client is to receive enoxaparin 30 mg subcutaneously. Available is enoxaparin 40 mg/mL. How many mL should the nurse administer?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A: The social worker is not the correct answer because they are not legally responsible for obtaining informed consent for an invasive procedure. The social worker is a professional who provides psychosocial support and advocacy for clients and families, such as counseling, referrals, or discharge planning.

Choice B: The nurse is not the correct answer because they are not legally responsible for obtaining informed consent for an invasive procedure. The nurse is a professional who provides direct care and education for clients and families, such as assessment, medication administration, or teaching. However, the nurse can assist the physician in obtaining informed consent by witnessing the client's signature, verifying the client's understanding, or documenting the process.

Choice C: The physician is the correct answer because they are legally responsible for obtaining informed consent for an invasive procedure. The physician is a professional who diagnoses and treats clients and families, such as performing surgery, prescribing medication, or ordering tests. The physician must explain the purpose, benefits, risks, alternatives, and consequences of the procedure to the client and obtain their voluntary agreement before proceeding.

Choice D: The unit secretary is not the correct answer because they are not legally responsible for obtaining informed consent for an invasive procedure. The unit secretary is a staff member who performs clerical and administrative tasks for the unit, such as answering phones, filing records, or scheduling appointments.

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.
