A nurse is caring for a client who recently had surgery for the insertion of a permanent pacemaker. Which of the following prescriptions should the nurse clarify?

Physical therapy

Serum cardiac enzyme levels

MRI of the chest

Low sodium diet

Answer and Explanation

The Correct Answer is C

Choice A reason: Physical therapy may be prescribed postoperatively to aid in recovery, but it does not directly interfere with the function of a pacemaker.

Choice B reason: Checking serum cardiac enzyme levels is a common practice after heart surgery to assess for any damage to the heart muscle, which would not typically require clarification in the context of pacemaker insertion.

Choice C reason: An MRI of the chest should be clarified with the healthcare provider because MRI can interfere with pacemaker function. Patients with pacemakers are generally advised to avoid MRI unless the pacemaker is Incompatible, due to the risk of the magnetic field affecting the device's operation.

Choice D reason: A low sodium diet may be recommended for patients with heart conditions to manage blood pressure and fluid retention, but it is not directly related to the care of a pacemaker.

Correct Answer is B

Explanation

Choice A reason: This statement is incorrect. Synthetic casts typically dry much faster than plaster casts. Plaster casts can take 24 to 48 hours to fully harden, while synthetic casts made from materials like fiberglass or plastic can harden within a few hours.

Choice B reason: This is the correct statement. Synthetic casts are indeed lighter than plaster casts. They are made from materials like fiberglass, which is lighter than the traditional plaster of Paris used in plaster casts.

Choice C reason: This statement is incorrect. Plaster casts are generally heavier than synthetic casts. The weight of a cast can be an important consideration, especially for children or for those who may have difficulty managing a heavier cast.

Choice D reason: This statement is incorrect. Both plaster and synthetic casts require specialized equipment for application, but it is not specific to plaster casts. The application involves similar steps for both types, including the use of a stockinette, padding, and then the casting material itself.

A. "The normal range for serum creatinine is 0.6 to 1.2 mg/dL for males and 0.5 to 1.1 mg/dL for females." B. "A GFR below 60 mL/min/1.73 m for three months or more suggests chronic kidney disease." C. "Blood urea nitrogen (BUN) levels should be between 7 and 20 mg/dL." D. "An increase in serum potassium can indicate hyperkalemia, which may be a sign of acute kidney injury."

Correct Answer is B

Explanation

Choice A reason: The normal range for serum creatinine is indeed 0.6 to 1.2 mg/dL for males and 0.5 to 1.1 mg/dL for females. Serum creatinine is a waste product from the normal breakdown of muscle tissue. As kidneys become impaired for any reason, the serum creatinine level rises due to poor clearance by the kidneys.

Choice B reason: A GFR below 60 mL/min/1.73 m for three months or more is one of the criteria for the diagnosis of chronic kidney disease. GFR is a measure of how well the kidneys filter blood, and a lower GFR indicates poorer kidney function.

Choice C reason: Blood urea nitrogen (BUN) levels should indeed be between 7 and 20 mg/dL. BUN measures the amount of nitrogen in your blood that comes from the waste product urea. Urea is made when protein is broken down in your body. BUN levels can rise with the level of protein in your diet and your kidney function[^10^].

Choice D reason: An increase in serum potassium can indicate hyperkalemia, which may be a sign of acute kidney injury. Potassium is a critical electrolyte, and its levels are tightly regulated by the kidneys. High levels can lead to dangerous heart rhythms.
