Correct Answer is C
Explanation
Hypertension is a risk factor for kidney disease. However, it can often be managed with medication. Controlled hypertension is not typically a contraindication for a kidney transplant.
B. If the client has maintained sobriety for a significant period, it might not be a contraindication. A history of alcohol abuse would require careful evaluation but doesn't necessarily preclude transplantation.
C. This is a contraindication for kidney transplantation. Severe heart disease can significantly increase the risks associated with surgery and post-transplant care.
D. Hepatitis C can be a challenge but it's not an absolute contraindication. Many transplant centers have protocols for managing hepatitis C-positive recipients.
Correct Answer is ["4"]
Explanation
To administer a total daily dose of 200 mg of imipramine divided equally every 12 hours, the nurse would need to give two doses of 100 mg each. Since the available tablets are 25 mg each, four tablets would be required to make up a single dose of 100 mg.
Therefore, the nurse should administer four tablets every 12 hours to meet the prescribed daily dosage.
