A nurse is teaching about how to suppress lactation with a client who is postpartum and bottle-feeding her newborn.
Which of the following instructions should the nurse include in the teaching?

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.

Choice A rationale:

Hanging the transfusion with dextrose 5% in 0.9% sodium chloride is incorrect. Packed red blood cells (PRBCs) are transfused with normal saline (0.9% sodium chloride) and not with dextrose-containing solutions. Using dextrose can cause the red blood cells to hemolyze.

Choice B rationale:

Infusing the transfusion over 5 hours is incorrect. PRBC transfusions are typically administered over 2-4 hours, not 5 hours. Infusing the blood too slowly may cause the patient discomfort and may also increase the risk of bacterial growth in the blood product.

Choice C rationale:

Using a 20-gauge IV catheter to transfuse the blood is incorrect. While a 20-gauge IV catheter is suitable for most blood transfusions, it may not be appropriate for older adults or patients with fragile veins. A smaller gauge, such as 22 or 24, might be more suitable to prevent phlebitis and ensure a steady flow without damaging the blood cells.

Choice D rationale:

Monitoring vital signs every hour throughout the transfusion is the correct action. During a blood transfusion, it's crucial to monitor the patient's vital signs frequently to detect any adverse reactions promptly. Vital signs, including blood pressure, heart rate, respiratory rate, and temperature, should be assessed before the transfusion, 15 minutes after starting the transfusion, and then hourly thereafter. This vigilant monitoring helps in identifying potential transfusion reactions, such as fever, chills, or hypotension, allowing for immediate intervention if needed.
