Correct Answer: C

Rationale: The most appropriate nursing action in this scenario is to notify the healthcare provider immediately. The client's presentation of calf pain, swelling, and warmth could be indicative of a deep vein thrombosis (DVT), which is a serious condition that requires prompt evaluation and intervention by the healthcare provider. DVT is a blood clot that forms in a deep vein, often in the leg, and if left untreated, it can lead to life-threatening complications such as pulmonary embolism. Therefore, timely communication with the healthcare provider is critical to ensure that the client receives the appropriate diagnostic testing and treatment to address the potential DVT. Applying warm compresses, encouraging ambulation, or administering NSAIDs would not be the first-line interventions for a suspected DVT and may even worsen the condition.

Correct Answer: B

Rationale: The medication given after a successful vaginal delivery that helps to hasten uterine contractility and control bleeding is typically an oxytocic agent, such as oxytocin. Oxytocin helps the uterus to contract effectively, which is important for preventing excessive bleeding after delivery. This medication is commonly used in the postpartum period to help the uterus return to its normal size and position. The supervisor reassured the newly hired nurse that everything will be fine because this medication will help promote uterine contractions and control bleeding, which are crucial steps in the postpartum management.

Correct Answer: A

Rationale: In a patient with acute kidney injury (AKI) secondary to sepsis in the ICU, the healthcare team should prioritize initiating continuous veno-venous hemofiltration (CVVH) for renal replacement therapy. CVVH is a form of continuous renal replacement therapy that helps support renal function by removing waste products, excess fluids, and electrolytes from the blood while providing hemodynamic stability. This intervention is crucial in managing fluid overload, electrolyte disturbances, and uremia associated with AKI in critically ill patients. It can also help improve overall outcomes and prevent further complications related to renal dysfunction in this setting. Administering diuretics, implementing fluid restriction, or performing a renal biopsy may not directly address the acute renal failure and may not provide the necessary renal support needed in this urgent situation.

Correct Answer: D

Rationale: The nurse should prioritize positioning the patient in a left lateral decubitus position during gastric lavage to ensure procedural effectiveness. This position helps to promote optimal drainage of fluid and gastric contents. Placing the patient in a left lateral position allows gravity to assist in the passage of fluid and prevents the risk of aspiration. It also helps to minimize the risk of complications such as reflux of lavage fluid into the respiratory tract. Proper positioning is essential in enhancing the success of the gastric lavage procedure and promoting patient safety.

Correct Answer: A

Rationale: The nurse should inform the public that rabies can be prevented. This is an extremely important piece of information to help raise awareness about the disease and promote preventive measures such as timely vaccination of both animals and humans. Rabies is a deadly viral infection that affects the central nervous system, and prevention through vaccination is highly effective in controlling its spread. By emphasizing the preventability of rabies, the nurse can educate the public on the importance of taking proactive steps to avoid contracting the disease.
