During CPR, which of the following actions should be performed immediately after activating the emergency response system?

Correct Answer: A

Rationale: After activating the emergency response system, the immediate priority in CPR is to begin chest compressions to support blood circulation. High-quality chest compressions are crucial in providing oxygen to vital organs, especially the brain, during cardiac arrest. Starting chest compressions promptly can improve the chances of survival for the person in need of CPR. Checking for breathing, performing abdominal thrusts, or assessing pulse should only be done after initiating chest compressions in the CPR sequence.

Correct Answer: A

Rationale: The healthcare team should prioritize administering lactulose or other ammonia-lowering agents to manage hepatic encephalopathy in a patient with acute liver failure. Hepatic encephalopathy is a neuropsychiatric syndrome that occurs in patients with liver dysfunction, leading to the accumulation of ammonia and other neurotoxic metabolites in the bloodstream. Lactulose works by acidifying the colon, which promotes the conversion of ammonia to ammonium, a less toxic form that can be excreted in the stool. By reducing the levels of ammonia, lactulose helps improve the neurological symptoms associated with hepatic encephalopathy.

Correct Answer: C

Rationale: The options provided focus on specific health indicators related to mother and child health in the Philippines among ASEAN countries that can be addressed by the Universal Health Law.

Correct Answer: D

Rationale: Insulinoma is a rare neuroendocrine tumor that arises from pancreatic beta cells, leading to excessive production and secretion of insulin. The symptoms described in the patient, such as weight loss, fatigue, nausea, vomiting, abdominal pain, hypoglycemia, and elevated insulin levels, are characteristic of insulinoma.

Correct Answer: B

Rationale: Molluscum contagiosum is a viral skin infection caused by the poxvirus. It typically presents as multiple dome-shaped, translucent papules with central umbilication on the face and trunk. The lesions are usually asymptomatic but can be itchy. Molluscum contagiosum is a common infection in children but can also occur in adults, especially those who are immunocompromised. The lesions can gradually increase in number over time. Basal cell carcinoma, sebaceous hyperplasia, and keratoacanthoma do not typically present with the characteristic features of molluscum contagiosum.

Correct Answer: C

Rationale: Checking the humidifier's water regularly is the priority precautionary measure that should be done by the nurse during oxygen therapy. Maintaining adequate water in the humidifier ensures proper humidification of the oxygen delivered to the patient, helping prevent mucous membrane dryness and irritation. Dry mucous membranes can lead to discomfort, increased risk of infection, and potential damage to the respiratory system. Therefore, ensuring the humidifier's water level is appropriate is crucial for the safety and well-being of the patient receiving oxygen therapy. Limiting visitors, attaching "No Smoking" signage, and connecting the bait to the oxygen tank are important precautions as well, but checking the humidifier's water is the priority measure in this scenario.

Correct Answer: A

Rationale: The best thing to do next is to turn off the fan immediately. The fact that the electric fan is stopping every now and then and sparking at intervals indicates a potential electrical issue or malfunction. This situation poses a safety hazard as it increases the risk of an electrical fire or damage to the fan. Turning off the fan immediately will help prevent any further damage or potential danger. After turning off the fan, it would be advisable to call for maintenance to inspect and repair the fan to ensure it is safe to use again.

Correct Answer: A

Rationale: Acute pyelonephritis is the most likely condition based on the patient presentation and urinalysis findings described. Acute pyelonephritis is an infection of the renal parenchyma and pelvis, typically caused by ascending bacteria from the lower urinary tract. The classic symptoms include fever, chills, flank pain, and costovertebral angle tenderness (tenderness over the kidneys). The presence of pyuria (pus in the urine) and bacteriuria (bacteria in the urine) on urinalysis further supports the diagnosis of acute pyelonephritis. It is crucial to diagnose and treat acute pyelonephritis promptly to prevent complications and recurrent infections.

Correct Answer: C

Rationale: An amniotic fluid embolism is a rare and life-threatening complication during labor and delivery. It occurs when amniotic fluid or fetal cells enter the maternal circulation, triggering a rapid immune response that can lead to cardiovascular collapse and respiratory failure. The priority nursing intervention for a woman in active labor diagnosed with an amniotic fluid embolism is to initiate cardiopulmonary resuscitation (CPR) to support her vital functions and circulation. Providing immediate CPR can help sustain her until further medical interventions can be implemented. Administering oxygen and preparing for a cesarean section may be necessary but should occur after CPR is initiated to stabilize the woman's condition. Inserting an indwelling urinary catheter is not the priority in this emergency situation, as maintaining adequate cardiac and respiratory function takes precedence.
