Nursing Elites

1. What is the proper technique for measuring a patient's blood pressure?

• A. Place the cuff at heart level and listen for Korotkoff sounds
• B. Ensure the patient is in a seated position and inflate the cuff to 180 mmHg
• C. Use a manual sphygmomanometer and measure blood pressure on both arms
• D. Monitor pulse rate and apply pressure to the brachial artery

Correct answer: A

Rationale: The correct technique for measuring blood pressure involves placing the cuff at heart level to ensure accurate readings. Listening for Korotkoff sounds helps determine the systolic and diastolic pressures. Choice B is incorrect as inflating the cuff to 180 mmHg is excessive and can lead to inaccurate readings. Choice C is incorrect as it is unnecessary to measure blood pressure on both arms unless there is a specific medical reason to do so. Choice D is incorrect as monitoring pulse rate and applying pressure to the brachial artery are not part of the standard blood pressure measurement technique.

2. What are the signs and symptoms of hyperkalemia and how should it be managed?

• A. Muscle weakness and cardiac arrhythmias; administer calcium gluconate
• B. Confusion and bradycardia; administer insulin and glucose
• C. Fatigue and irregular heart rate; administer diuretics
• D. Nausea and vomiting; administer sodium bicarbonate

Correct answer: A

Rationale: The signs and symptoms of hyperkalemia include muscle weakness and cardiac arrhythmias, making choice A correct. Hyperkalemia can lead to dangerous cardiac effects, and calcium gluconate is used to stabilize the heart by antagonizing the effects of potassium. Choices B, C, and D describe symptoms and interventions that are not typically associated with hyperkalemia. Confusion and bradycardia are not common in hyperkalemia, and insulin and glucose are used in hyperkalemia only under specific circumstances. Fatigue and irregular heart rate are vague symptoms, and diuretics are not the primary treatment for hyperkalemia. Nausea and vomiting are nonspecific symptoms and sodium bicarbonate is not indicated for the management of hyperkalemia.

3. What is the best nursing intervention for a patient with hyperkalemia?

• A. Administer potassium-wasting diuretics
• B. Encourage a low-potassium diet
• C. Administer potassium supplements
• D. Administer IV fluids

Correct answer: A

Rationale: The correct answer is to administer potassium-wasting diuretics. Hyperkalemia, which is high potassium levels, is managed by promoting the excretion of potassium from the body. Potassium-wasting diuretics help the kidneys eliminate excess potassium. Encouraging a low-potassium diet (choice B) is important for long-term management but not the immediate intervention for hyperkalemia. Administering potassium supplements (choice C) would worsen the condition by further increasing potassium levels. Administering IV fluids (choice D) may help with hydration but does not directly address the high potassium levels characteristic of hyperkalemia.

4. What are the common signs and symptoms of dehydration in the elderly?

• A. Dry mouth, confusion, and decreased skin turgor
• B. Increased heart rate and muscle cramps
• C. Fever, rapid breathing, and increased urine output
• D. Increased thirst and difficulty walking

Correct answer: A

Rationale: Corrected Rationale: Dehydration in the elderly is often signaled by dry mouth, confusion, and decreased skin turgor due to reduced fluid intake. Choice A is the correct answer as these are common signs and symptoms of dehydration in the elderly.\nIncorrect Rationales: Option B (Increased heart rate and muscle cramps) are more associated with conditions like hyperthyroidism or electrolyte imbalances rather than dehydration. Option C (Fever, rapid breathing, and increased urine output) are signs of other medical conditions such as infections or diabetes insipidus. Option D (Increased thirst and difficulty walking) can be seen in various situations but are not specific signs of dehydration in the elderly.

5. What is the proper technique for measuring blood pressure manually?

• A. Use a stethoscope to listen for the Korotkoff sounds
• B. Ensure the patient is seated with the arm supported
• C. Use a manual sphygmomanometer
• D. Deflate the cuff slowly while listening to the heartbeat

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.
