Correct Answer: A

Rationale: In this scenario, the client is experiencing frequent contractions with a short duration and an elevated fetal heart rate, indicating potential fetal distress. Discontinuing the oxytocin infusion is crucial to prevent further complications and restore normal fetal parameters. Increasing or maintaining the oxytocin infusion could exacerbate the situation, leading to more distress for the fetus. Decreasing the oxytocin infusion may not be sufficient to address the current issue and could delay the improvement of fetal well-being.

Correct Answer: A

Rationale: Corrected Rationale: Tremors can indicate lithium toxicity, which should be reported to the provider for further evaluation. Tremors are a significant sign of lithium toxicity and can lead to serious complications if not addressed promptly. Increased thirst, weight gain, and diarrhea are common side effects of lithium but are not typically indicative of toxicity. Therefore, the nurse should prioritize reporting tremors as it requires immediate attention.

Correct Answer: B

Rationale: The correct answer is B: Loss of interest in usual activities. Clients with PTSD often exhibit symptoms such as numbing, which can manifest as a loss of interest in activities they once enjoyed. Choice A, dependence on family and friends, is more indicative of seeking support rather than a direct symptom of PTSD. Choice C, ritualistic behavior, is more commonly associated with conditions like obsessive-compulsive disorder. Choice D, passive-aggressive behavior, is not a typical finding in clients with PTSD.

Correct Answer: B

Rationale: The correct answer is B: Pallor. Pallor, which is paleness of the skin, is a common sign of anemia due to a decreased number of red blood cells or hemoglobin levels. This results in reduced oxygen-carrying capacity, leading to the paleness of the skin. Choice A, increased appetite, is not typically associated with anemia. Choice C, tachycardia (increased heart rate), can be present in anemia as the body compensates for decreased oxygenation. Choice D, hypertension (high blood pressure), is not a common finding in anemia; instead, low blood pressure may be observed due to decreased blood volume.

Correct Answer: A

Rationale: The correct answer is to administer anticoagulants. Administering anticoagulants is crucial in the management of deep vein thrombosis (DVT) as it helps prevent the clot from growing larger or dislodging, potentially causing a life-threatening pulmonary embolism. While monitoring oxygen levels, applying compression stockings, and encouraging ambulation are important aspects of DVT management, administering anticoagulants is the most critical intervention to prevent further complications.
