Correct Answer: B

Rationale: Administering the feeding over 30 minutes helps prevent complications such as aspiration. Placing the child in an upright position after the feeding is recommended to reduce the risk of aspiration. It is essential to change the feeding bag and tubing every 3 days to maintain asepsis and prevent infections. Warming the formula in a warm water bath is the correct method as using a microwave can create hot spots that may burn the child's mouth or throat.

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: A

Rationale: When St. John's wort, an herbal supplement, is taken with citalopram, a selective serotonin reuptake inhibitor (SSRI), there is a risk of serotonin syndrome. Serotonin syndrome is a serious condition that can occur when there is an excess of serotonin in the body, leading to symptoms such as confusion, hallucinations, rapid heart rate, increased body temperature, and more. Monitoring for serotonin syndrome is crucial when these substances are taken together to prevent any potential harm to the client.

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: B

Rationale: Dyspnea is a key finding indicating fluid overload in a client receiving packed RBCs. Fluid overload can lead to pulmonary edema, causing difficulty breathing or shortness of breath (dyspnea). Low back pain is not typically associated with fluid overload but can be more related to musculoskeletal issues. Hypotension and thready pulse are more indicative of hypovolemia (low fluid volume), not fluid overload.
