Correct Answer: C

Rationale: When a nurse notices a discrepancy between the surgical consent form and the planned procedure, it is essential to consult the surgeon for clarification. The surgeon is the primary decision-maker regarding the surgical procedure and can provide insight into why the discrepancy exists and how to proceed. It is crucial to ensure that everyone is on the same page before moving forward with the surgery to prevent errors, ensure patient safety, and maintain legal and ethical standards. Consulting the surgeon allows for the issue to be addressed promptly and for the appropriate steps to be taken to resolve the discrepancy before proceeding with the surgery.

Correct Answer: B

Rationale: Record-keeping is not an optional task; it is a critical aspect of professional nursing practice. As a nurse, maintaining accurate and timely records is essential for providing quality care, ensuring legal and ethical standards are met, and promoting patient safety. Failure to keep thorough records can lead to serious consequences such as compromising patient care, violating regulations, and even facing legal consequences. Thus, record-keeping should be seen as a mandatory part of the professional duty of nurses rather than an optional task that can be done when circumstances allow.

Correct Answer: C

Rationale: Hypokalemia (low levels of potassium) increases the risk of digoxin toxicity. This is because digoxin competes with potassium for binding sites on the sodium-potassium ATPase pump in the cell membrane. When potassium levels are low, there is an increased binding of digoxin to these pumps, leading to enhanced entry of calcium into the cells. This can result in an increased intracellular calcium concentration, leading to digoxin toxicity and potential cardiac arrhythmias. Therefore, monitoring and correcting potassium levels is crucial in patients prescribed digoxin to reduce the risk of toxicity.

Correct Answer: D

Rationale: Nursing mothers should not wash their nipples with soap and water prior to feeding. Using soap can dry out the skin and potentially lead to irritation or cracking of the nipple, which can increase the risk of mastitis. It is recommended to simply clean the nipples with water, if necessary.

Correct Answer: D

Rationale: Sudden chest pain, dyspnea, and tachycardia in a postpartum client can be indicative of serious conditions such as pulmonary embolism or myocardial infarction. These conditions are emergencies that require immediate medical attention. Notifying the healthcare provider immediately is the priority to ensure prompt evaluation and intervention to address the potential life-threatening situation. While other nursing interventions such as elevating the head of the bed, providing supplemental oxygen therapy, and administering analgesics may be necessary, they should be done after notifying the healthcare provider to ensure appropriate management of the underlying cause.
