Nurses usually complain they have no personal life because of rotating shifts The following are three major ways to create personal time, ЕХСЕРТ _____.
- A. delegate work to others
- B. fill every moment with tasks or chores
- C. eliminate tasks that add no value
- D. hire someone else to do the work
Correct Answer: C
Rationale: To create personal time as a nurse with rotating shifts, it is important to prioritize personal well-being and make time for oneself. By eliminating tasks that add no value, nurses can streamline their workload and focus on essential responsibilities. This can help in reducing unnecessary stress and allowing for more personal time outside of work. Delegating work to others and filling every moment with tasks or chores may not necessarily create personal time, as it can keep nurses constantly busy and overwhelmed. Hiring someone else to do the work may not always be feasible or practical in a nursing setting, but by eliminating non-essential tasks, nurses can better manage their time and have more opportunities for personal activities and self-care.

As part of the teaching plan, Nurse Angie teaches that oral contraceptives contains estrogen. Which of the following is the Action of Estrogen? It inhibits the _______.
- A. GnRH thereby inhibiting FSH and LH productions.
- B. Luteinising Hormone (LH) thereby inhibiting ovulation.
- C. Testosterone production.
- D. Follicle Stimulating Hormone (FSH) thereby inhibiting maturation of ovum.
Correct Answer: A
Rationale: Estrogen exerts negative feedback on the hypothalamus by inhibiting the release of GnRH (Gonadotropin-Releasing Hormone). GnRH plays a crucial role in the regulation of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) production from the pituitary gland. By inhibiting the release of GnRH, estrogen ultimately leads to a decrease in FSH and LH levels. This process helps to suppress the maturation of the egg and ovulation, providing contraceptive effects.
A patient presents with petechiae, purpura, and mucosal bleeding. Laboratory tests reveal thrombocytopenia, elevated serum creatinine, and schistocytes on peripheral blood smear. Which of the following conditions is most likely to cause these findings?
- A. Thrombotic thrombocytopenic purpura (TTP)
- B. Idiopathic thrombocytopenic purpura (ITP)
- C. Hemolytic uremic syndrome (HUS)
- D. Disseminated intravascular coagulation (DIC)
Correct Answer: A
Rationale: Thrombotic thrombocytopenic purpura (TTP) is a rare but serious condition characterized by microangiopathic hemolytic anemia, thrombocytopenia, neurological abnormalities, fever, and renal dysfunction. The classic pentad of symptoms includes fever, neurologic changes, renal impairment, thrombocytopenia, and microangiopathic hemolytic anemia. The presence of petechiae, purpura, and mucosal bleeding along with thrombocytopenia, elevated serum creatinine, and schistocytes on peripheral blood smear are consistent with TTP. In TTP, there is usually a deficiency of ADAMTS13 (a von Willebrand factor-cleaving protease) leading to excessive platelet adhesion, aggregation, and microthrombi formation within small blood vessels.
