Nursing Elites

1. A nurse is teaching a client with heart failure about dietary restrictions. What food should be limited?

• A. Bananas
• B. Leafy green vegetables
• C. Potatoes
• D. Whole grains

Correct answer: A

Rationale: The correct answer is A: Bananas. Bananas are high in potassium, which should be limited in clients with heart failure to prevent electrolyte imbalances. While leafy green vegetables and whole grains are generally healthy options, they are not typically restricted in heart failure patients. Potatoes, although they contain potassium, are not as high in potassium as bananas and are not usually restricted as strictly.

2. What are the key differences between systolic and diastolic heart failure?

• A. Systolic: Reduced ejection fraction; Diastolic: Preserved ejection fraction
• B. Systolic: Preserved ejection fraction; Diastolic: Reduced ejection fraction
• C. Systolic: Right-sided heart failure; Diastolic: Left-sided heart failure
• D. Systolic: Pulmonary congestion; Diastolic: Systemic congestion

Correct answer: A

Rationale: The correct answer is A. Systolic heart failure is characterized by reduced ejection fraction, meaning the heart is not pumping effectively. Diastolic heart failure, on the other hand, is characterized by preserved ejection fraction, indicating that the heart has difficulty relaxing and filling properly. Choices B, C, and D are incorrect because they do not accurately describe the key differences between systolic and diastolic heart failure.

3. A nurse at a long-term care facility is transcribing new prescriptions for four clients. Which of the following prescriptions is accurately transcribed by the nurse?

• A. KCl 10 mEq PO once daily
• B. KCl 20 mEq PO once daily
• C. Potassium gluconate PO
• D. Potassium chloride 20 mEq PO every morning

Correct answer: D

Rationale: The correct answer is D because it accurately transcribes the prescription by specifying the medication (Potassium chloride), the dose (20 mEq), the route (PO for by mouth), and the frequency (every morning). Choice A is incorrect as it specifies a lower dose compared to the correct prescription. Choice B is incorrect due to an inaccurate dose. Choice C is incorrect as it lacks specificity regarding the type of potassium prescribed and the dose.

4. 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.

5. How should a healthcare provider respond to a patient with a suspected pulmonary embolism?

• A. Administer oxygen and call for emergency assistance
• B. Position the patient in a prone position and give fluids
• C. Administer anticoagulants and elevate the patient's legs
• D. Administer thrombolytics and perform chest physiotherapy

Correct answer: A

Rationale: Administering oxygen and calling for emergency assistance are the immediate priorities when managing a suspected pulmonary embolism. Oxygen helps support the patient's respiratory function, while emergency assistance is crucial for further evaluation and treatment. Positioning the patient in a prone position or giving fluids can worsen the condition by impeding blood flow. Administering anticoagulants may be part of the treatment plan but is not the initial response. Thrombolytics and chest physiotherapy are not first-line treatments for suspected pulmonary embolism and can even be harmful without prior evaluation.
