A nurse is reviewing the laboratory data of a patient who is scheduled for a liver biopsy. Which of the following values should the nurse report to the provider?
Platelets 60,000/mm (150,000 to 400,000/mm)
Ammonia 55 mcg/dL (10 to 80 mcg/dL)
Aspartate aminotransferase 34 units/L (0 to 34 units/L)
Bilirubin 1.0 mg/dL (0.3 to 1.0 mg/dL) .
The Correct Answer is A
Choice A.
Choice A rationale
A platelet count of 60,000/mm is significantly lower than the normal range of 150,000 to 400,000/mm. Platelets are crucial for blood clotting, and a low count can increase the risk of bleeding, which is a serious concern for a patient scheduled for a liver biopsy. Therefore, the nurse should report this value to the provider.
Choice B rationale
An ammonia level of 55 mcg/dL falls within the normal range of 10 to 80 mcg/dL1. Ammonia is a byproduct of protein metabolism and is converted to urea in the liver for excretion. Normal levels do not typically pose a concern for liver biopsy.
Choice C rationale
Aspartate aminotransferase (AST) is an enzyme found in various tissues, including the liver. An AST level of 34 units/L is at the upper limit of the normal range (0 to 34 units/L)1. While it’s
important to monitor, it does not necessarily need to be reported to the provider before a liver biopsy if there are no other signs of liver disease.
Choice D rationale
A bilirubin level of 1.0 mg/dL is within the normal range (0.3 to 1.0 mg/dL)1. Bilirubin is a waste product from the breakdown of red blood cells and is processed by the liver. Normal levels indicate that the liver is functioning properly in this regard.

Correct Answer is D
Explanation
Choice A rationale
Metoprolol is a beta-blocker that affects the heart and circulation. It does not typically cause elevated blood glucose levels.
Choice B rationale
Metoprolol is used to treat high blood pressure, not increase it. It works by relaxing blood vessels and slowing heart rate to improve blood flow and decrease blood pressure.
Choice C rationale
Metoprolol does not typically reduce bronchospasms. In fact, it can sometimes cause breathing problems such as shortness of breath, cough, and wheezing.
Choice D rationale
Metoprolol is known to lower heart rate. This is one of the ways it helps to reduce blood pressure and relieve strains on the heart.
Correct Answer is B
Explanation
Choice A rationale
Limiting physical activity until bladder continence is achieved is not typically part of a bladder training program. Physical activity can actually help improve bladder control by strengthening the pelvic floor muscles.
Choice B rationale
Instructing the client to void at scheduled times throughout the day is a key component of bladder training. This helps retrain the bladder to hold urine for longer periods and reduces episodes of incontinence.
Choice C rationale
Instructing the client to void as soon as they feel the urge is not typically part of a bladder training program. The goal of bladder training is to gradually extend the time between voids.
Choice D rationale
Encouraging the client to contract the abdominal muscles when they experience the urge to void is not typically part of a bladder training program. This could potentially lead to more leakage.
