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. Treatment typically

Correct Answer: B

Rationale: The independent variable in an experiment is the variable that is manipulated or determined by the researcher. In this hypothesis, the nurse is suggesting that the age of the patient (elderly vs. younger) influences the aggressiveness of treatment received. Therefore, the age of the patient is the independent variable in this scenario. The dependent variable would be the degree of treatment received, as it is expected to be influenced by the independent variable, which is the age of the patient.

Correct Answer: D

Rationale: Involution refers to the process of the uterus returning to its nonpregnant state after childbirth. During pregnancy, the uterus undergoes significant changes and enlarges to accommodate the growing fetus. After childbirth, the uterus begins to contract, leading to a decrease in its size and a return to its pre-pregnant state. This process involves the shedding of the excess endometrial tissue and the reduction of the size of the uterine muscle fibers. It is a normal and essential process for postpartum recovery. Failure of the uterus to undergo proper involution is known as subinvolution, which can lead to complications such as postpartum hemorrhage.

Correct Answer: C

Rationale: Lamotrigine (Lamictal) is known to cause a serious rash, such as Stevens-Johnson syndrome or toxic epidermal necrolysis, which can be life-threatening. Therefore, it is crucial for patients taking Lamotrigine to be aware of this potential side effect and report any skin rashes to their healthcare provider promptly. Early detection and appropriate management are essential in preventing serious complications related to these rashes.

Correct Answer: B

Rationale: The IR (Incident Report) typically focuses on the details surrounding an incident or event, such as what happened, who was/were involved, and who witnessed the incident. Information about daily medications given to the patient is not usually included in an incident report, unless it directly relates to the incident itself (e.g., medication error). The primary focus of an incident report is to document the incident in a clear and factual manner for record-keeping and analysis purposes.
