A nurse is caring for a client who is receiving heparin 3,800 units subcutaneously daily. Available is heparin 5,000 units/mL. How many mL should the nurse administer? Round to thenearesttenth

A. Folic acid deficiency anemia:

Folic acid deficiency anemia is characterized by a lack of folate (vitamin B9), which is essential for red blood cell production. Symptoms can include weakness and fatigue, similar to iron-deficiency anemia. However, folic acid deficiency anemia typically does not cause heavy menstrual periods. Laboratory findings may show a low level of folate in the blood, but the hemoglobin level of 8 g/dL and hematocrit level of 28 g/dL alone do not specifically indicate folic acid deficiency anemia without considering other factors like mean corpuscular volume (MCV) and red blood cell indices.

B. Pernicious anemia:

Pernicious anemia is caused by a lack of intrinsic factor, a substance needed for the absorption of vitamin B12. It can lead to symptoms such as weakness and fatigue. However, heavy menstrual periods are not a characteristic feature of pernicious anemia. Laboratory findings may show a low hemoglobin and hematocrit level, but again, other factors such as MCV and vitamin B12 levels would be needed to confirm this type of anemia.

C. Iron-deficiency anemia:

Iron-deficiency anemia occurs due to insufficient iron stores in the body, leading to decreased hemoglobin and hematocrit levels. This type of anemia is commonly associated with symptoms like weakness, fatigue, and heavy menstrual periods in women due to blood loss. The client's hemoglobin level of 8 g/dL and hematocrit level of 28 g/dL are consistent with iron-deficiency anemia, making this the most likely choice based on the information provided.

D. Sickle cell anemia:

Sickle cell anemia is a genetic disorder characterized by abnormal hemoglobin that causes red blood cells to become sickle-shaped and less flexible. It typically presents with symptoms such as anemia, pain crises, and organ damage. However, the client's symptoms of weakness, fatigue, and heavy menstrual periods are not specific to sickle cell anemia. Additionally, sickle cell anemia would have different laboratory findings, including a different pattern on peripheral blood smear and hemoglobin electrophoresis.

A. Sinus bradycardia: Sinus bradycardia is characterized by a regular rhythm with a heart rate less than 60 beats per minute. In this case, the heart rate is 64 beats per minute, which falls within the normal range, not consistent with sinus bradycardia.

B. Sinus arrhythmia: Sinus arrhythmia typically presents as a variation in the R-R interval with respiration, often seen as an irregularity in the heart rate. The provided characteristics describe a regular rhythm, so sinus arrhythmia is not the correct interpretation.

C. Sinus tachycardia: Sinus tachycardia is characterized by a regular rhythm with a heart rate greater than 100 beats per minute. The heart rate in this case is 64 beats per minute, which is not indicative of sinus tachycardia.

D. Normal sinus rhythm: Normal sinus rhythm refers to a regular rhythm with a heart rate between 60 and 100 beats per minute, P waves preceding each QRS complex, a normal PR interval (0.12 to 0.20 seconds), and normal QRS complex duration (less than 0.12 seconds). The provided characteristics, including regular P waves, regular QRS complexes, a PR interval of 0.16 seconds, and a heart rate of 64 beats per minute, align with a normal sinus rhythm interpretation.
