A nurse is assessing a client who received 2 units of packed RBCs 48 hr ago. Which of the following findings should indicate to the nurse that the therapy has been effective?

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:

Fidelity refers to the principle of being loyal, faithful, and keeping promises. It does not specifically relate to providing accurate information about treatment effects. In this scenario, the nurse is discussing the potential adverse effects of a treatment, which falls under the domain of providing accurate and truthful information to the client.

Choice B rationale:

Beneficence is the ethical principle of doing good and promoting the well-being of the patient. While educating the client about potential adverse effects is a form of beneficence, the specific principle demonstrated in this scenario is veracity, which is the duty to tell the truth. The nurse is being truthful about the potential side effect (lightheadedness) while clarifying that it should not affect memory.

Choice C rationale:

Veracity is the ethical principle of truth-telling. In this scenario, the nurse is demonstrating veracity by providing honest and accurate information to the client about the potential adverse effects of transcranial magnetic stimulation. By being truthful, the nurse upholds the ethical principle of veracity.

Choice D rationale:

Autonomy refers to the principle of respecting the patient's right to make decisions about their own healthcare. While respecting autonomy is important, the nurse's action in this scenario specifically pertains to providing accurate information (veracity) rather than solely focusing on the client's decision-making autonomy.
