Correct Answer: A

Rationale: Pulmonary congestion is a common manifestation of left-sided heart failure. When the left side of the heart fails, blood backs up into the lungs, leading to pulmonary congestion. This can result in symptoms such as frothy, pink-tinged sputum due to the presence of blood in the respiratory secretions. Jugular vein distention, weight gain, and bradypnea are also associated with heart failure, but frothy, pink sputum specifically indicates pulmonary congestion in this scenario.

Correct Answer: B

Rationale: During a gastric lavage procedure for upper gastrointestinal bleeding, inserting a large-bore NG tube is essential to effectively remove gastric contents and blood. This tube allows for efficient irrigation and suction, aiding in the removal of harmful substances from the stomach. Instilling a large volume of solution or using a cold irrigation solution can lead to complications such as fluid overload or hypothermia. Instructing the client to lie on their right side is not directly related to the gastric lavage procedure.

Correct Answer: B

Rationale: CINAHL (Cumulative Index to Nursing and Allied Health Literature) is a comprehensive database that specializes in nursing and allied health literature. It is a valuable resource for healthcare professionals seeking nursing-related articles, making it the most appropriate option for the nurse caring for a client with questions about pancreatic cancer.

Correct Answer: C

Rationale: Postterm pregnancy with oligohydramnios is a contraindication for the use of oxytocin due to the increased risk of uterine hyperstimulation and fetal distress. Oxytocin can further stress the fetus in this scenario, potentially leading to adverse outcomes. Therefore, it is crucial for the nurse to recognize this contraindication to ensure the safety of both the mother and the baby during labor.

Correct Answer: A

Rationale: To calculate the expected delivery date using Nagele's rule, begin by subtracting 3 months from the first day of the last menstrual period (April 12th), which results in January 12th. Then, add 7 days. Therefore, the expected delivery date would be January 19th (0119). This calculation method helps healthcare professionals estimate the client's due date.
