Correct Answer: B

Rationale: The correct instruction that the nurse should include in the teaching plan for a client prescribed methotrexate is to report any signs of infection immediately. Methotrexate can suppress the immune system, making the individual more susceptible to infections. Reporting signs of infection promptly allows for timely intervention. Choices A, C, and D are incorrect. Avoiding folic acid supplements is not recommended because methotrexate can lead to folate deficiency, so supplementation may be necessary. There is no direct correlation between fluid intake limitation and methotrexate use. Increasing high-calcium foods is not specifically related to methotrexate therapy for rheumatoid arthritis.

Correct Answer: A

Rationale: Elevated serum amylase is the most indicative laboratory result of acute pancreatitis. In this condition, the pancreas becomes inflamed, leading to the leakage of amylase and lipase into the bloodstream. Elevated serum amylase levels are a classic finding in acute pancreatitis. Choices B, C, and D are not typically associated with acute pancreatitis. Decreased serum bilirubin, increased blood urea nitrogen (BUN), and decreased alkaline phosphatase levels are not specific markers for acute pancreatitis.

Correct Answer: B

Rationale: Gastroesophageal reflux (GER) in infants is typically treated by thickening the formula or breast milk with cereal. This helps reduce reflux episodes by making the feedings heavier and less likely to come back up. Placing the infant NPO (nothing by mouth) is not the typical treatment for GER as infants need proper nutrition for growth. Placing the infant to sleep on the side is not recommended due to the risk of SIDS; infants should be placed on their back to sleep. Switching the infant to cow's milk is also not a treatment for GER, as cow's milk can be harder to digest and may exacerbate symptoms.

Correct Answer: B

Rationale: Hydrocephalus is the additional congenital malformation expected in 80% of infants with a myelomeningocele. Myelomeningocele is commonly associated with hydrocephalus due to the abnormal accumulation of cerebrospinal fluid in the brain. Cerebral palsy (Choice A) is a motor disorder but not typically associated with myelomeningocele. Meningitis (Choice C) is an infection of the meninges and is not a congenital malformation. Neuroblastoma (Choice D) is a type of cancer that originates in immature nerve cells and is not a typical association with myelomeningocele.

Correct Answer: D

Rationale: In this scenario, the nurse should provide the client with oral swabs to moisten his mouth. This intervention helps alleviate the client's thirst without increasing fluid intake, which is essential in managing AKI. Removing all sources of liquids from the client's room (Choice A) may not address the underlying issue of thirst and could lead to increased frustration. Allowing the family to give the client ice chips (Choice B) would add to the client's fluid intake, contradicting the restriction. Restricting family visiting (Choice C) is not necessary and does not directly address the client's thirst.
