A nurse is caring for a client who is receiving a continuous heparin infusion. Which of the following laboratory tests should the nurse review prior to adjusting the client's heparin?
aPTT
PT
INR
WBC count
The Correct Answer is A
- A is correct because aPTT (activated partial thromboplastin time) measures the effectiveness of heparin therapy and guides dosage adjustments.
- B is incorrect because PT (prothrombin time) measures the effectiveness of warfarin therapy, not heparin.
- C is incorrect because INR (international normalized ratio) is a standardized version of PT that also monitors warfarin therapy, not heparin.
- D is incorrect because WBC count (white blood cell count) measures the body's immune response and has no relation to heparin therapy.

Correct Answer is ["persistent nausea and significant weight loss"]
Explanation
Electrolyte imbalance in pregnant clients is often associated with conditions that lead to dehydration and nutritional deficiencies. In this scenario, the key indicators are persistent nausea and significant weight loss.
- Persistent nausea can lead to reduced food and fluid intake. This condition, especially if prolonged, can cause dehydration and electrolyte imbalances due to the loss of essential minerals and nutrients that are not being replenished due to inadequate dietary intake.
- Significant weight loss, particularly the amount described in the scenario (6.8 kg or 15 lb), is a clear sign of inadequate nutritional intake and can further exacerbate the risk of electrolyte imbalance. It indicates that the body is not receiving enough nutrients, which is crucial for maintaining electrolyte balance.
The other options, while related to diet and fluid intake, are more specific to the client's eating habits and do not directly point to the primary cause of potential electrolyte imbalance in the context of this scenario. Therefore, the most comprehensive and medically relevant choice is (A) Persistent nausea and significant weight loss.
Correct Answer is D
Explanation
- A is incorrect because IV tubing for total parenteral nutrition should be changed every 24 hours to prevent infection.
- B is incorrect because abdominal distention is not an expected effect of total parenteral nutrition. It could indicate a complication such as fluid overload or bowel obstruction.
- C is incorrect because gastric residual is not relevant for total parenteral nutrition, which bypasses the gastrointestinal tract.
- D is correct because weight measurement is an important indicator of fluid balance and nutritional status for clients receiving total parenteral nutrition.
