Correct Answer: D

Rationale: Testing the fluid with a nitrazine strip is the appropriate technique to differentiate between amniotic fluid and urine. This test helps in determining if the fluid leakage is amniotic fluid, which is crucial for guiding further management and ensuring appropriate care for the client during the third trimester of pregnancy. Inserting a straight urinary catheter to drain the bladder (Choice A) is unnecessary and invasive in this scenario as the concern is fluid leakage, not urinary retention. Scanning the bladder for urinary retention (Choice B) is also not indicated since the client reported fluid leakage, not retention. Palpating the suprapubic area for fetal head position (Choice C) is unrelated to assessing fluid leakage and not the appropriate technique in this situation.

Correct Answer: B

Rationale: The correct action for the nurse to take is to administer the scheduled dose of digoxin. A heart rate of 128 bpm in a two-year-old child with heart failure falls within the safe range for digoxin administration. It indicates that the child's heart rate is not excessively low, which could be a concern for administering digoxin. Therefore, proceeding with the scheduled dose is appropriate in this scenario. Determining the pulse deficit (Choice A) is not necessary in this situation as the heart rate is already obtained. Calculating the safe dose range (Choice C) is not required as the heart rate is within the safe range. Reviewing the serum digoxin level (Choice D) is not needed at this point since the heart rate indicates that administering the next dose is appropriate.

Correct Answer: B

Rationale: The correct answer is Calcium. In this scenario, the child is displaying symptoms of muscular irritability and oozing blood, which are indicative of hypocalcemia. Calcium levels are crucial to monitor after multiple blood transfusions to prevent complications such as hypocalcemia, which can lead to these symptoms. Therefore, obtaining a serum calcium value is essential for the nurse to assess and address the child's condition effectively. CO2 combining power, Sodium, and Chloride levels are not directly associated with the symptoms described and are not the priority in this situation.

Correct Answer: C

Rationale: An abnormal oral glucose tolerance test result is indicative of gestational diabetes. This test is crucial in diagnosing gestational diabetes as it evaluates how well the body processes glucose after a sugary drink. Reporting abnormal results promptly allows for timely intervention and management to ensure the well-being of both the mother and the baby. The other options are not the primary tests used to diagnose gestational diabetes. Hemoglobin A1C is not recommended for diagnosing gestational diabetes as it reflects long-term glucose control. Postprandial blood glucose and fasting blood glucose tests are not as sensitive as the oral glucose tolerance test for diagnosing gestational diabetes.
