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: A

Rationale: Lying prone with a pillow on the abdomen is the most helpful intervention in relieving postpartum uterine contractions or 'afterpains.' This position provides counter-pressure and support to the uterus, helping to alleviate discomfort and promote uterine involution. Choice B, using a breast pump, is not effective in relieving afterpains as it focuses on milk expression. Massaging the abdomen (Choice C) may help with discomfort but does not provide the same level of support as lying prone with a pillow. Giving oxytocic medications (Choice D) is not typically the first-line intervention for afterpains unless there are specific medical indications.

Correct Answer: A

Rationale: Following the administration of epidural anesthesia, the most crucial assessment for the healthcare provider to conduct is monitoring maternal blood pressure. Epidural anesthesia can lead to hypotension as a common side effect, which can have significant implications for both the mother and the fetus. Therefore, close monitoring of maternal blood pressure is essential to detect and manage any hypotensive episodes promptly. Choices B, C, and D are important assessments during labor and delivery, but in this specific scenario of post-epidural anesthesia, monitoring maternal blood pressure takes precedence due to the potential risk of hypotension.

Correct Answer: A

Rationale: To confirm respiratory distress syndrome (RDS) in a newborn, the nurse should assess diaphragmatic breathing. In RDS, the baby may have difficulty breathing due to immature lungs, leading to shallow, rapid breathing movements. Assessing diaphragmatic breathing directly evaluates the respiratory effort and can help identify the presence of RDS. Choice B, assessing heart sounds, is not specific to diagnosing RDS but could be relevant for other conditions. Choice C, monitoring blood oxygen levels, is important but alone may not confirm RDS. Choice D, checking for signs of infection, is not a direct indicator of RDS but rather suggests a different issue.

Correct Answer: A

Rationale: In a postpartum client exhibiting symptoms of a spinal headache, applying an abdominal binder is a priority action. The abdominal binder can help reduce the severity of a spinal headache by increasing intra-abdominal pressure, which may relieve pressure on the dural sac and alleviate symptoms. This intervention can be performed promptly by the nurse to provide immediate relief while waiting for further evaluation and management by the anesthesiologist. Cleansing the spinal injection site (Choice B) is not the priority in this situation as the headache is likely due to a dural puncture during epidural anesthesia rather than infection. Inserting an indwelling Foley catheter (Choice C) and placing procedure equipment at the bedside (Choice D) are not the appropriate actions to address a spinal headache and should not take precedence over applying an abdominal binder.
