Nursing Elites

1. Furosemide (Lasix) is a drug used to _____.

• A. activate vitamin D
• B. stimulate appetite
• C. lower cholesterol
• D. mobilize fluids

Correct answer: D

Rationale: Furosemide is a diuretic that helps mobilize fluids by increasing urine output, often used to treat conditions like edema and heart failure.

2. What does a QRS Complex represent in an ECG reading?

• A. Atrial depolarization
• B. Ventricular repolarization
• C. Ventricular depolarization
• D. End of ventricular depolarization

Correct answer: C

Rationale: The QRS Complex in an ECG reading represents ventricular depolarization, which is the process of the heart's ventricles preparing to contract by changing the electrical charge in the cell, hence choice 'C' is the correct answer. Choice 'A' is incorrect because atrial depolarization is represented by the P wave in an ECG reading, not the QRS Complex. Choice 'B' is incorrect as ventricular repolarization is depicted by the T wave, not the QRS Complex. Finally, choice 'D' is also incorrect because the QRS Complex is not the end of ventricular depolarization, but the process itself.

3. Medication for treating high blood cholesterol levels should not be used for most people unless:

• A. The patient has at least three major risk factors for coronary heart disease
• B. The patient has been experiencing symptoms of coronary heart disease for at least three months
• C. The patient's medical insurance covers prescription drugs
• D. Treatment with Therapeutic Lifestyle Changes (TLC) alone is unsuccessful after three months

Correct answer: D

Rationale: The correct answer is choice D because medication for high cholesterol is typically not considered unless Therapeutic Lifestyle Changes (TLC), which include diet and exercise, have not proven effective after a three-month period. This approach ensures that lifestyle modifications are given a fair chance to lower cholesterol levels before resorting to medication. Choice A is incorrect because the number of risk factors for coronary heart disease does not dictate when to begin medication; it is about the effectiveness of lifestyle changes. Choice B is incorrect as the duration of coronary heart disease symptoms does not determine when to start medication; the focus is on the response to TLC. Choice C is incorrect because the coverage of prescription drugs by the patient's insurance does not influence the medical decision to use medication for high cholesterol; it is based on medical necessity and effectiveness of prior interventions.

4. The past history of Camila would most probably reveal that her premorbid personality is:

• A. schizoid
• B. extrovert
• C. ambivert
• D. cycloid

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.

5. A client is being instructed by a nurse about foods that should be included in a low-fiber diet. Which statement by the client indicates understanding?

• A. I can cut up carrots and celery sticks for my lunch.
• B. I will eat a bran muffin for my mid-morning snack.
• C. I will have oatmeal with skim milk for my breakfast.
• D. I should choose canned peaches for my fruit serving.

Correct answer: D

Rationale: The correct answer is D because canned peaches are lower in fiber compared to the other options. Carrots, celery sticks, bran muffins, and oatmeal are high-fiber choices, which are not suitable for a low-fiber diet. Choosing canned peaches aligns with the requirements of a low-fiber diet.
