Actions of progesterone include the following except:

Correct Answer: A

Rationale: The correct answer is A: Rise in body temperature. Progesterone does not directly cause a rise in body temperature; this is primarily regulated by the hypothalamus. Progesterone's main actions include endometrial proliferation, proliferation of acini in the mammary gland, and suppression of cell-mediated immunity. Endometrial proliferation prepares the uterus for implantation, mammary gland proliferation prepares for lactation, and suppression of immunity prevents rejection of the fetus during pregnancy. Other choices are incorrect because they are well-documented actions of progesterone.

Correct Answer: D

Rationale: The correct answer is D (2-4 weeks) because rotating injection sites every 2-4 weeks helps prevent lipodystrophy and tissue damage. Insulin absorption may vary with frequent rotation, affecting glucose control. Choice A is too frequent and may lead to overuse of specific sites, increasing the risk of complications. Choice B is also too frequent and doesn't allow enough time for the tissue to recover. Choice C is too long, increasing the likelihood of uneven insulin absorption and potential complications. Rotation every 2-4 weeks strikes a balance between preventing damage and ensuring consistent insulin absorption.

Correct Answer: B

Rationale: The correct answer is B: Norepinephrine. The sympathetic postganglionic neurons release norepinephrine as the main neurotransmitter, which acts on target organs to elicit the fight-or-flight response. Norepinephrine is responsible for increasing heart rate, blood pressure, and dilating airways. Acetylcholine is released by preganglionic neurons in both sympathetic and parasympathetic systems, not postganglionic neurons in the sympathetic system. Option C is incorrect as acetylcholine is not typically released by postganglionic sympathetic neurons. Option D, arginine, is not a neurotransmitter commonly associated with the sympathetic nervous system.

Correct Answer: A

Rationale: Norepinephrine is a vasoconstrictor that increases blood pressure. In hypovolemic shock, there is insufficient blood volume, so vasoconstriction can worsen tissue perfusion. Neurogenic shock is characterized by vasodilation, so norepinephrine can help increase blood pressure. Choice C is incomplete and irrelevant. Norepinephrine is not used to treat diabetes.

Correct Answer: D

Rationale: The correct answer is D because chemotherapy dosing is usually based on the total body weight of the patient. Weighing and measuring the height of the patient on the day of administration helps ensure accurate dosing calculations. A: Before administering chemotherapy the nurse should - This is a general statement and does not specifically address the need for accurate dosing based on body weight. B: Get the body mass index (BMI) - BMI alone may not provide accurate dosing information as it does not directly measure total body weight. C: Ask the client about intake and output - Intake and output monitoring is important for assessing fluid balance but does not directly relate to chemotherapy dosing based on body weight.
