A nurse is reviewing the medical record of a client who is to undergo open heart surgery. Which of the following findings should the nurse report to the provider as a contraindication to receiving heparin?

Choice A Reason:

Decreased bowel sounds: Hyponatremia (low serum sodium levels) primarily affects the nervous system and can lead to neurological symptoms such as confusion, seizures, and headache. It doesn't typically directly affect bowel sounds. Therefore, this option is not the expected finding.

Choice B Reason:

Increased central venous pressure: As I mentioned earlier, hyponatremia can lead to cerebral edema (swelling of the brain) due to the movement of water into cells. This swelling can increase intracranial pressure and, in turn, affect the central venous pressure by impacting blood return to the heart. While the relationship between hyponatremia and central venous pressure might be complex, it's a more relevant consideration compared to the other options provided.

Choice C Reason:

Hyperreflexia: Hyponatremia can lead to changes in brain function and neurological symptoms, including altered reflexes. Hyperreflexia, which is an exaggerated response to stimuli, can indeed be a manifestation of hyponatremia, making this option a potential expected finding.

Choice D Reason:

Contusion: A contusion is a bruise that results from damage to blood vessels beneath the skin. Hyponatremia is not directly related to the formation of contusions. This option is not the expected finding in a client with low serum sodium levels.

B. Open the first flap of the sterile package toward the nurse's body: When opening a sterile package, the nurse should open the first flap away from their body to prevent potential contamination from falling particles. This action helps maintain the sterility of the contents inside.

D. Place a surgical pack with a sterile drape on the work surface: Placing the surgical pack with a sterile drape on the work surface ensures that the sterile field is properly established. The sterile drape provides a clean and sterile area for the nurse to perform the dressing change.

Incorrect answers:

A. Select a work surface at the nurse's waist level: While it is important to select a work surface at an appropriate height for the nurse's comfort and ergonomics, the height of the work surface does not directly affect the maintenance of a sterile field.

C. Grasp 2.5 cm (1 in) of the outer edge to open the surgical wrap: When opening a sterile package, the nurse should grasp the inner edge of the sterile wrap to maintain the sterility of the contents. Grasping the outer edge can potentially lead to contamination of the sterile field.

E. Apply sterile gloves before opening the pack: Sterile gloves should be applied after the sterile field is established. Opening the sterile pack and setting up the sterile field should be done with clean (non-sterile) hands to avoid contaminating the contents. Once the sterile field is set up, the nurse can don sterile gloves before actually touching the sterile items.
