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 C

Explanation

Choice A reason: This is incorrect. While gentle hair care is important, it is not as critical as sun protection for SLE patients.

Choice B reason: This is incorrect. Powder can be drying, and SLE patients often need to keep their skin moisturized.

Choice C reason: This is correct. SLE patients are often photosensitive and need to protect their skin from UV rays.

Choice D reason: This is incorrect. SLE patients should keep their skin well moisturized to prevent dryness.

A. Urine specific gravity of 1.020 B. Serum sodium of 165 mEq/L C. Hematocrit of 48% D. Blood urea nitrogen (BUN) of 12 mg/dL

Correct Answer is A

Explanation

Choice A reason: Urine specific gravity measures the kidney's ability to concentrate urine. A normal range is typically 1.005–1.030. A value of 1.020 indicates adequate hydration and suggests that the patient is responding well to IV fluid therapy.

Choice B reason: Serum sodium levels reflect electrolyte balance. The normal range is 135–145 mEq/L. A level of 165 mEq/L is significantly elevated, indicating hypernatremia, which could be a sign of inadequate hydration and not a positive response to treatment.

Choice C reason: Hematocrit represents the proportion of blood volume occupied by red blood cells. Normal ranges are 38.3–48.6% for men and 35.5–44.9% for women. A hematocrit of 48% is at the upper limit of normal and does not specifically indicate the effectiveness of dehydration treatment.

Choice D reason: Blood urea nitrogen (BUN) levels can indicate renal function and hydration status. The normal range is 7–20 mg/dL. A BUN of 12 mg/dL is within the normal range and does not specifically reflect the patient's response to IV fluids for dehydration.
