Adult Health Nursing First Chapter Quizlet

Correct Answer: B

Rationale: The laboratory test used to monitor the therapeutic effect of warfarin therapy is the International Normalized Ratio (INR). Warfarin is a commonly prescribed anticoagulant medication that works by inhibiting the action of vitamin K-dependent clotting factors. Maintaining the INR within the target range specific to the indication for anticoagulation (e.g., DVT prevention or treatment) is essential to balance the risk of bleeding and clotting.

Correct Answer: C

Rationale: When a nurse discovers a discrepancy between the medication order and the patient's medication record, the priority action is to verify the medication order with the prescriber to ensure accuracy and patient safety. Administering the medication without clarification can put the patient at risk. Documenting the discrepancy and informing the charge nurse is important, but it should not delay verifying the order with the prescriber. Contacting the pharmacy for clarification may be necessary in some cases, but the immediate action should be to confirm the prescription with the prescriber to prevent errors and ensure the patient receives the correct medication.

Correct Answer: B

Rationale: In preparing for a possible earthquake as part of Safe Practice Environment (SPE) standards, the QA team should prioritize attention on Electrical wires (I) and Combustible materials (II).

Correct Answer: D

Rationale: Acute respiratory distress syndrome (ARDS) is a severe condition characterized by widespread inflammation in the lungs leading to increased pulmonary vascular permeability, non-cardiogenic pulmonary edema, and respiratory failure. In ARDS, the alveolar-capillary barrier is disrupted, resulting in fluid accumulation in the alveoli and impaired gas exchange.

Correct Answer: B

Rationale: Magnesium sulfate is used to prevent eclampsia, but it can lead to toxicity if levels become too high. One common sign of magnesium toxicity is increased deep tendon reflexes, also known as hyperreflexia. This occurs because magnesium is a muscle relaxant, and elevated levels can lead to over-relaxation of muscles, causing an exaggerated reflex response. Other signs of magnesium toxicity include respiratory depression, decreased urine output, and cardiac arrest. Therefore, in a woman receiving intravenous magnesium sulfate during labor, an increase in deep tendon reflexes would indicate potential toxicity and require immediate intervention.
