Nursing Elites

1. To prevent injury and strain on the muscles, the nurse should observe proper body mechanics. Among the following, which is a principle of proper body mechanics?

• A. Broaden the space between the feet
• B. Push instead of pull
• C. Move the object away from the body when lifting
• D. Bend at the waist, not on the knees

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

2. Which statement does not describe a potential role of minerals in the body?

• A. they provide calories and energy to the body
• B. they help maintain fluid balance in the body
• C. they give teeth and bone their strength
• D. they help muscles contract

Correct answer: A

Rationale: Minerals do not provide calories or energy; instead, they play various roles such as building strong bones and teeth, maintaining fluid balance, and supporting muscle contractions.

3. Which of the following is reflected in an ECG due to hypokalemia?

• A. Tall T waves and Pathologic Q wave
• B. Widening QRS Complex and U wave
• C. None of the above
• D. Both A and B

Correct answer: B

Rationale: Hypokalemia, a condition characterized by low levels of potassium in the blood, is reflected in an ECG by a widening QRS Complex and a U wave. This is because potassium plays a key role in the electrical activity of the heart, and its deficiency can lead to abnormalities in the heart's rhythm as represented by these specific changes on the ECG. Choice A is incorrect as tall T waves and pathologic Q waves are more commonly associated with hyperkalemia or myocardial infarction, respectively, rather than hypokalemia. Choices C and D are also incorrect as they do not accurately reflect the ECG changes caused by hypokalemia.

4. The preferred route of administration of medication in the most acute care situations is which of the following routes?

• A. Intravenous C. Subcutaneous
• B. Epidural D. Intramuscular
• C.
• D.

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.

5. Which substance would most likely need to be restricted in patients with heart failure who use diuretics to help reduce fluid retention?

• A. potassium
• B. magnesium
• C. sodium
• D. chloride

Correct answer: C

Rationale: Sodium restriction is crucial in heart failure management to prevent fluid retention, which can worsen symptoms of heart failure.
