Rationale: A positive antinuclear antibody (ANA) titer is a significant finding in clients with systemic lupus erythematosus (SLE) as it indicates active disease. This result should be reported to the provider for further evaluation and management. Choices A, C, and D are within normal ranges and not specifically indicative of disease activity in SLE. Therefore, they do not require immediate reporting to the provider.

Correct Answer: D

Rationale: Nonpitting ankle edema is a concerning sign of worsening preeclampsia due to fluid retention and should be reported immediately. Proteinuria of 1+ is a common finding in preeclampsia. A blood pressure of 120/80 mm Hg is within normal limits. A respiratory rate of 18/min is also within normal range. Therefore, choices A, B, and C are not as urgent as nonpitting ankle edema in this scenario.

Correct Answer: D

Rationale: The correct instruction for cord care is to keep the cord stump dry until it falls off. This helps prevent infection and promotes healing. Choice A is incorrect because the timing of when the cord stump falls off can vary, usually between 1-3 weeks. Choice B is incorrect as a black cord stump can be a normal part of the healing process, so it is unnecessary to contact the provider for this reason. Choice C is incorrect because cleaning the cord with hydrogen peroxide daily is not recommended as it can delay healing and cause irritation.

Correct Answer: C

Rationale: During the Passover holiday, individuals practicing Orthodox Judaism adhere to specific dietary restrictions, which include consuming unleavened bread. Providing unleavened bread aligns with the client's religious beliefs and dietary requirements. Choices A, B, and D are incorrect. Serving chicken with cream sauce, avoiding fish with fins and scales, and avoiding foods containing lamb are not directly related to the dietary restrictions observed during the Passover holiday in Orthodox Judaism.

Correct Answer: C

Rationale: In Cushing's disease, there is increased cortisol production, which can lead to various metabolic disturbances. One of the common findings is an increased serum potassium level.
