Correct Answer: D

Rationale: Corrected Rationale: Blurred vision is a classic sign of digoxin toxicity, indicating a potential overdose. It is crucial to recognize this symptom promptly and report it to the healthcare provider for immediate intervention. Bradycardia and nausea are common side effects of digoxin but not specific indicators of toxicity. Tachycardia is unlikely in digoxin toxicity since it usually causes a decrease in heart rate.

Correct Answer: D

Rationale: After childbirth, it is normal for the fundus to be firm and at the level of the umbilicus, heart rate to be around 80/min, and blood pressure to be slightly elevated. However, a constant trickle of bright red blood from the vagina is concerning as it could indicate postpartum hemorrhage. This finding should be reported promptly to the healthcare provider for further evaluation and intervention. Choices A, B, and C are within expected postpartum parameters and do not indicate an immediate need for intervention.

Correct Answer: C

Rationale: The correct action the nurse should take when administering potassium chloride IV to a client with hypokalemia is to infuse the medication at a rate of 10 mEq/hr. This slow infusion rate is crucial to prevent the development of hyperkalemia, a potentially dangerous condition. Option A is incorrect because giving the medication as a bolus over 10 minutes can lead to adverse effects. Option B is incorrect as potassium chloride does not necessarily need to be diluted before administration in this scenario. Option D is incorrect as administering the medication undiluted can also increase the risk of hyperkalemia.

Correct Answer: B

Rationale: Applying a fetal heart rate monitor is the priority action in this scenario as it helps assess the well-being of the fetus during labor. This monitoring is crucial to detect any signs of fetal distress and guide interventions. Inserting an indwelling urinary catheter (Choice A) is not a priority at this time unless there are specific indications. Initiating fundal massage (Choice C) is not necessary in this situation as the focus should be on fetal assessment. Initiating an oxytocin IV infusion (Choice D) is not indicated until the stage of labor and the progress of labor are determined.

Correct Answer: A

Rationale: The correct answer is A. Weight loss of 0.5 kg (1.1 lb) in 24 hours is an indication that furosemide is effectively reducing fluid retention. This medication works by promoting diuresis, resulting in increased urine output, which could lead to weight loss. While increased urinary output (choice B) is a common effect of furosemide, weight loss is a more specific indicator of its effectiveness. Blood pressure (choice C) and decreased peripheral edema (choice D) can be influenced by various factors and are not direct indicators of furosemide's effectiveness in reducing fluid retention.
