What is the proper technique for measuring blood pressure manually?

Correct Answer: A

Rationale: The correct technique for measuring blood pressure manually involves using a stethoscope to listen for the Korotkoff sounds. Choice B, ensuring the patient is seated with the arm supported, is important but not the specific technique for measuring blood pressure. Choice C, using a manual sphygmomanometer, is a necessary tool but not the technique itself. Choice D, deflating the cuff slowly while listening to the heartbeat, is not the correct technique as the deflation should be done while listening for the Korotkoff sounds to determine the systolic and diastolic blood pressure readings.

Correct Answer: A

Rationale: The correct way to assess and manage a patient with delirium is by assessing for confusion and reorienting the patient. Delirium is characterized by acute confusion and disturbance in attention, so reorienting the patient to time, place, and person can help improve their awareness and cognition. Providing a quiet environment is important to reduce stimuli that can exacerbate delirium, but administering sedatives may worsen the condition. Oxygen therapy and monitoring vital signs are essential aspects of general patient care but are not specific to managing delirium. Providing pain relief is important for overall patient comfort but may not directly address the core issue of delirium.

Correct Answer: A

Rationale: The correct signs of hyperkalemia include elevated potassium levels and muscle weakness. The treatment involves administering calcium gluconate to help stabilize the heart. Choice B is incorrect as hyperkalemia is characterized by elevated, not decreased, potassium levels. Choice C is incorrect as hyperkalemia does not involve elevated sodium levels, and the treatment is not sodium bicarbonate. Choice D is incorrect as hyperkalemia does not lead to low sodium levels, and sodium chloride is not the treatment for hyperkalemia.

Correct Answer: A

Rationale: The correct answer is A: Administer antibiotics and monitor oxygen levels. Antibiotics are essential to treat the infection caused by bacteria in pneumonia, while monitoring oxygen levels helps ensure adequate oxygenation. Administering bronchodilators and encouraging deep breathing, as in choice B, are more commonly associated with managing conditions like asthma or COPD, not pneumonia. Providing fluids and monitoring for dehydration, as in choice C, are important for various conditions but not specific to pneumonia management. Administering oxygen and providing bed rest, as in choice D, may be supportive measures in pneumonia treatment, but the key intervention is administering antibiotics.

Correct Answer: A

Rationale: The correct intervention for a patient with hypokalemia is to administer potassium supplements and monitor the ECG. Potassium supplements help correct the low potassium levels in the body, while ECG monitoring is essential to detect any cardiac arrhythmias associated with hypokalemia. Choice B is incorrect because a high-sodium diet would worsen hypokalemia by further depleting potassium levels. Choice C is incorrect as it only focuses on monitoring symptoms and providing dietary education, but does not address the immediate need to correct potassium levels. Choice D is also incorrect as administering diuretics would exacerbate hypokalemia by increasing potassium loss.
