Correct Answer: A

Rationale: In this scenario, the client is experiencing uterine hyperstimulation with contractions every 45 seconds lasting 90 seconds. This frequency and duration of contractions can lead to fetal distress. The appropriate nursing action is to discontinue the oxytocin infusion immediately to prevent complications. Increasing or maintaining the oxytocin infusion would exacerbate the situation, while decreasing it may not be sufficient to address the issue effectively.

Correct Answer: C

Rationale: When toxicity from magnesium sulfate occurs, the nurse should administer calcium gluconate IV as it is the antidote for magnesium sulfate toxicity. Positioning the client supine may not address the toxicity issue. Administering dextrose 5% is not the appropriate intervention for magnesium sulfate toxicity. Methylergonovine is used to manage postpartum hemorrhage and is not indicated for magnesium sulfate toxicity.

Correct Answer: C

Rationale: The correct action for a nurse when administering enoxaparin for DVT prevention is to inject the medication into the lateral abdominal wall. This is the recommended site for enoxaparin administration. Expelling the air bubble is unnecessary and may lead to a dosage error. Massaging the injection site is not recommended as it can cause bruising. Administering an NSAID for injection site discomfort is not necessary as discomfort should be minimal and transient.

Correct Answer: A

Rationale: In cases of magnesium sulfate toxicity, administering calcium gluconate IV is crucial as it is the antidote for magnesium sulfate. Calcium gluconate helps reverse the effects of magnesium sulfate, especially when signs of toxicity like respiratory depression or loss of reflexes occur. Increasing the magnesium sulfate infusion would worsen toxicity. Administering IV fluids may be beneficial for hydration but does not address magnesium sulfate toxicity. Hydralazine is used to manage hypertension, not magnesium sulfate toxicity.

Correct Answer: A

Rationale: Abnormal mouth movements are a key sign of dysphagia, a condition commonly seen in stroke clients. Dysphagia refers to difficulty swallowing, which can manifest as abnormal movements of the mouth during eating or drinking. In stroke patients, dysphagia increases the risk of aspiration, where food or liquids enter the airway instead of the esophagus, leading to potential complications such as pneumonia. Choices B, C, and D are not directly indicative of dysphagia. Inability to stand without assistance may indicate motor deficits, paralysis of the right arm suggests a neurological impairment, and loss of appetite can be a non-specific symptom in many conditions but does not specifically point to dysphagia.
