Correct Answer: B

Rationale: In end-stage liver disease, the liver's inability to convert ammonia into urea leads to elevated ammonia levels. Elevated ammonia levels can result in hepatic encephalopathy, a serious complication. Therefore, the correct answer is B. Elevated albumin (Choice A) is not typically seen in end-stage liver disease as liver dysfunction often leads to decreased albumin levels. Decreased total bilirubin (Choice C) is unlikely in end-stage liver disease, as bilirubin levels tend to be elevated due to impaired liver function. Decreased prothrombin time (Choice D) is also not expected in end-stage liver disease, as impaired liver function results in prolonged prothrombin time.

Correct Answer: A

Rationale: The correct answer is A. Clients with chronic kidney disease should limit their intake of phosphorus because high phosphorus levels can lead to bone disease and cardiovascular problems. Increasing foods high in potassium (choice B) is not recommended as it can be harmful to individuals with kidney disease. Decreasing intake of foods high in iron (choice C) is not specifically indicated for chronic kidney disease. Increasing calcium supplements (choice D) may not be necessary and can potentially lead to hypercalcemia in individuals with kidney disease.

Correct Answer: D

Rationale: The correct answer is D. Swelling in the feet can indicate worsening heart failure due to fluid retention, and clients should report this to their healthcare provider immediately. Choices A, B, and C are incorrect because weighing once a week may not provide timely information on fluid retention, timing of diuretic medication is usually advised in the morning to prevent nocturia, and limiting fluid intake to 3 liters per day may not be appropriate for all clients with heart failure.

Correct Answer: D

Rationale: The vastus lateralis is the preferred site for IM injections in infants under 1 year of age because it is well developed and easily accessible compared to other muscle groups. The ventrogluteal and deltoid sites are not typically used for infants due to muscle development and size. The dorsogluteal site is not recommended for infants or young children due to its proximity to major nerves and blood vessels.

Correct Answer: C

Rationale: The correct answer is C. Cool feet bilaterally in a client with a long leg cast may indicate compromised circulation, which is a medical emergency that requires immediate intervention. Choices A, B, and D do not present immediate life-threatening conditions. Tingling in the fingers following a thyroidectomy may indicate hypocalcemia but does not require immediate attention. Dark, foul-smelling urine with decreased urine output indicates a possible urinary tract infection or dehydration but can be addressed after attending to the client with compromised circulation. A productive cough and a normal oral temperature do not suggest an urgent condition compared to compromised circulation in a client with a long leg cast.
