The nurse is caring for a 24 year old post-partum client with a diagnosis of cardiomyopathy. The nurse understands that which of the following types of cardiomyopathy can be associated with childbirth?
Dilated
Restrictive
Hypertrophic
Myocarditis
The Correct Answer is A
A. Dilated: Peripartum cardiomyopathy is a form of dilated cardiomyopathy that can occur during the last month of pregnancy or within five months after delivery. It is characterized by ventricular dilation and impaired systolic function, leading to signs of heart failure in previously healthy women.
B. Restrictive: Restrictive cardiomyopathy is a rare form that involves impaired ventricular filling due to stiffened myocardial walls. It is typically associated with infiltrative diseases like amyloidosis or sarcoidosis, not with pregnancy or the postpartum period.
C. Hypertrophic: Hypertrophic cardiomyopathy is usually genetic and involves thickened ventricular walls, especially the interventricular septum. It is not linked to childbirth and tends to present earlier in life with symptoms like syncope or sudden cardiac death in young athletes.
D. Myocarditis: Myocarditis involves inflammation of the heart muscle due to infection or autoimmune causes. Although it can occur postpartum, it is not specifically associated with childbirth like peripartum cardiomyopathy, which is a distinct clinical entity.

Correct Answer is ["200"]
Explanation
Volume ordered is 1 L.
Convert the total volume to milliliters (mL)
1 L = 1000 mL.
Total volume in mL = 1 L × 1000 mL/L = 1000 mL
Total infusion time = 5 hours
Calculate the infusion rate in milliliters per hour (mL/hr).
Infusion rate (mL/hr) = Total volume (mL) / Total infusion time (hours)
= 1000 mL / 5 hours
= 200
The appropriate setting is 200 mL/hr.
Correct Answer is A
Explanation
A. Dehydration: The elevated hemoglobin (17 g/dL) and hematocrit (54%), along with an increased BUN (28 mg/dL) and normal creatinine, suggest hemoconcentration, a key indicator of dehydration. Small bowel obstruction often leads to fluid loss through vomiting and third spacing into the bowel, contributing to this condition.
B. Infection: The WBC count is normal at 8.5, which does not support an active infection. Infections typically result in leukocytosis (WBC >10.5), especially in acute abdominal conditions.
C. Renal insufficiency: Although BUN is elevated, creatinine remains normal (1.1 mg/dL). This pattern, particularly with hemoconcentration, supports pre-renal azotemia due to dehydration, not intrinsic renal insufficiency.
D. Internal bleeding: Internal bleeding typically causes a decrease in hemoglobin and hematocrit due to blood loss. The elevated values in this case rule out active bleeding and instead indicate fluid volume deficit.
