What is the best intervention for a patient experiencing hypoxia?

Correct Answer: A

Rationale: The best intervention for a patient experiencing hypoxia is to administer oxygen. Oxygen therapy helps improve oxygenation levels in the blood, addressing the underlying cause of hypoxia. Repositioning the patient, providing humidified air, and chest physiotherapy may be beneficial in certain situations but are not the primary interventions for hypoxia. Administering oxygen is crucial to quickly alleviate hypoxia and support the patient's respiratory function.

Correct Answer: A

Rationale: Limiting fluid intake is essential in managing patients with chronic kidney disease to prevent fluid overload, which can worsen kidney function. Increasing potassium intake is not recommended as patients with kidney disease often need to limit potassium. Providing a high-protein diet may put extra strain on the kidneys, so it is not ideal. Administering IV antibiotics is not a standard treatment for chronic kidney disease.

Correct Answer: A

Rationale: The correct answer is A: Monitor daily weight. Daily weight monitoring is the most accurate method to assess fluid overload in patients with heart failure. Changes in weight can indicate fluid retention before visible signs like jugular vein distention or pitting edema appear. Checking for jugular vein distention (choice B) is helpful but may not be as sensitive as daily weight monitoring. Pitting edema (choice C) and fluid retention (choice D) are signs of fluid overload, but daily weight monitoring is a more proactive approach to detect changes early.

Correct Answer: A

Rationale: The correct answer is to monitor aPTT. Activated Partial Thromboplastin Time (aPTT) is crucial for patients on heparin therapy as it helps determine the clotting ability of the blood. By monitoring aPTT, healthcare providers can adjust the dosage of heparin to maintain therapeutic levels and prevent bleeding complications. Monitoring INR is more commonly associated with warfarin therapy, not heparin. Monitoring platelet count is important for assessing the risk of bleeding or clotting disorders but is not specific to heparin therapy. Monitoring sodium levels is not directly related to assessing the effectiveness or safety of heparin therapy.

Correct Answer: A

Rationale: Administering oxygen is the most critical intervention for a patient in respiratory distress as it helps improve oxygenation levels. Oxygen therapy aims to increase oxygen saturation in the blood, providing relief and support during episodes of respiratory distress. Administering bronchodilators may be beneficial in some cases, but oxygen therapy takes precedence in addressing the underlying issue of inadequate oxygenation. Repositioning the patient may help optimize ventilation but does not directly address the primary need for increased oxygen. Providing humidified air can offer comfort but does not address the urgent need for improved oxygen levels in a patient experiencing respiratory distress.
