A nurse is preparing a client who has a small bowel obstruction for insertion of a nasogastric tube. Which of the following equipment should the nurse gather prior to the procedure?

b. Migraines with aura.

Explanation:

Migraines with aura are considered a contraindication to the use of oral contraceptives. Auras are neurological symptoms that occur before or during migraines and can include visual disturbances, sensory changes, or speech difficulties. Women who experience migraines with aura have an increased risk of ischemic stroke when taking oral contraceptives. Therefore, it is important to identify this condition as a contraindication and explore alternative contraceptive options for the client.

The other options (a. History of renal calculus, c. BMI of 25, d. History of cholecystectomy) are not contraindications to the use of oral contraceptives.

ESR is a laboratory test that measures the rate at which red blood cells settle in a vertical tube of blood over a specific period of time. An elevated ESR is a nonspecific indicator of inflammation in the body, including infections. In the presence of an infection, the body releases certain substances that can increase the rate at which red blood cells settle, leading to an elevated ESR.

Decreased platelet count is not typically associated with infection. Low platelet count, known as thrombocytopenia, can be caused by various factors such as certain medications, autoimmune disorders, or bone marrow disorders. Infection may cause other changes in blood counts, but decreased platelets are not a direct indicator of infection.

Decreased hemoglobin levels, known as anemia, can be caused by various factors such as nutritional deficiencies, chronic diseases, or blood loss. While some infections can lead to anemia indirectly, decreased hemoglobin is not a specific indicator of infection.

Increased iron levels, known as hyperferritinemia, can occur in various conditions, including infections, but it is not a direct indicator of infection. It is important to assess the overall clinical picture and other laboratory findings to determine the cause of increased iron levels.
