Correct Answer: C

Rationale: The symptoms described in the scenario - chest pain, dyspnea, and cyanosis - are indicative of a potential air embolism. Air embolism occurs when air enters the bloodstream, leading to blockages in blood vessels and impeding oxygen delivery to tissues. In patients receiving Total Parenteral Nutrition (TPN) through intravenous lines, the risk of air embolism exists during line manipulations, disconnections, or improper priming of the tubing. The sudden onset of symptoms like chest pain and cyanosis in a patient on TPN should raise suspicion for an air embolism, as it requires immediate intervention to prevent further complications such as cardiac arrest or stroke.

Correct Answer: B

Rationale: Nurses are bound by strict confidentiality and privacy regulations in their profession. If a nurse fails to keep a patient's personal information confidential and discloses it without authorization, they can be charged with invasion of privacy. Invasion of privacy is the wrongful intrusion into a person's private affairs without their consent, and it is a serious violation of ethical and legal standards in healthcare. Nurses must always prioritize patient confidentiality to maintain trust and uphold ethical standards in their practice.

Correct Answer: B

Rationale: Uterine hyperstimulation is a condition in which the uterus contracts too frequently or too intensely, leading to decreased blood flow and oxygenation to the placenta. This can result in maternal fatigue and decreased fetal oxygenation due to the lack of sufficient rest intervals between contractions. Uterine hyperstimulation can be caused by factors such as the use of synthetic oxytocin (Pitocin) to induce or augment labor, uterine abnormalities, or maternal conditions like pre-eclampsia. It is important for the nurse to assess for uterine hyperstimulation in a woman experiencing frequent and intense contractions to intervene promptly and prevent adverse outcomes for both the mother and the baby.

Correct Answer: B

Rationale: In cases of acute intracerebral hemorrhage (ICH) with elevated intracranial pressure (ICP), a significant factor contributing to the elevated ICP is often the mass effect caused by the hematoma within the brain. Performing an emergent craniotomy for hematoma evacuation is a critical intervention to relieve the pressure within the intracranial space, thereby mitigating the risk of herniation and further neurological damage. While other interventions such as hypertonic saline therapy, head-of-bed elevation, and sedative medications may have supporting roles in managing ICP, none address the primary cause of elevated ICP in cases of acute intracerebral hemorrhage as effectively as hematoma evacuation through craniotomy.

Correct Answer: C

Rationale: The most likely causative agent in this scenario is Borrelia burgdorferi, which is the bacterium responsible for causing Lyme disease. The classic presentation of Lyme disease includes fever, malaise, and a skin lesion resembling a "bull's eye" rash, known as erythema migrans. This rash typically appears at the site of a tick bite. If left untreated, Lyme disease can progress to involve multiple organ systems and lead to more severe complications. Plasmodium falciparum is the causative agent of malaria, which typically presents with symptoms such as fever, chills, and fatigue, but it does not cause a "bull's eye" rash. Trypanosoma cruzi is the parasite responsible for Chagas disease, which presents with symptoms such as fever, swelling at the site of entry (typically the bite wound), and enlarged lymph nodes, but it does not
