Nursing Elites

1. Which chamber of the heart receives oxygenated blood from the lungs?

• A. Left atrium
• B. Right atrium
• C. Left ventricle
• D. Right ventricle

Correct answer: A

Rationale: The correct answer is A, the left atrium. The left atrium receives oxygenated blood from the lungs through the pulmonary veins. This blood is then pumped into the left ventricle before being circulated throughout the body. The right atrium, represented by choice B, actually receives deoxygenated blood from the body through the vena cava. Choices C and D, the left ventricle and right ventricle respectively, are chambers involved in pumping blood out of the heart to the body and lungs, rather than receiving blood from the lungs.

2. A nurse is orienting a newly licensed nurse on the purpose of administering vecuronium to a client who has acute respiratory distress syndrome (ARDS). Which of the following statements by the newly licensed nurse indicates understanding of the teaching?

• A. This medication is given to treat infection.
• B. This medication is given to facilitate ventilation.
• C. This medication is given to decrease inflammation.
• D. This medication is given to reduce anxiety.

Correct answer: B

Rationale: Vecuronium is a neuromuscular blocking agent that is used to facilitate ventilation by inducing muscle paralysis, which can help improve oxygenation in patients with ARDS. It does not treat infection, decrease inflammation, or reduce anxiety. Understanding the purpose of vecuronium administration is crucial for providing safe and effective care to patients with respiratory distress.

3. The four main concepts common to nursing that appear in each of the current conceptual models are:

• A. Person, nursing, environment, medicine
• B. Person, health, nursing, support systems
• C. Person, health, psychology, nursing
• D. Person, environment, health, nursing

Correct answer: D

Rationale: The four main concepts common to nursing that appear in each of the current conceptual models are person, environment, health, and nursing. These concepts form the foundational principles that guide nursing practice and theory.

4. A client is being educated by a healthcare provider on the purpose of taking a bronchodilator. Which of the following client statements indicates an understanding of the teaching?

• A. ''This medication can decrease my immune response.''
• B. ''I take this medication to prevent asthma attacks.''
• C. ''I need to take this medication with food.''
• D. ''This medication has a slow onset to treat my symptoms.''

Correct answer: B

Rationale: The correct answer is, 'I take this medication to prevent asthma attacks.' Bronchodilators are commonly used to relieve bronchospasm in conditions such as asthma. This medication helps to dilate the airways, making it easier to breathe and preventing asthma attacks. The other options are incorrect: option A is inaccurate as bronchodilators do not decrease immune responses, option C is incorrect as bronchodilators are typically taken on an empty stomach for better absorption, and option D is false as bronchodilators have a rapid onset to provide quick relief of symptoms.

5. Which hormone is secreted by the Islets of Langerhans?

• A. Progesterone
• B. Testosterone
• C. Insulin
• D. Hemoglobin

Correct answer: C

Rationale: Insulin is the correct answer. It is the hormone secreted by the Islets of Langerhans in the pancreas. These specialized cells regulate blood sugar levels by releasing insulin in response to high blood glucose levels. Insulin aids in glucose absorption by cells, lowering blood sugar levels. Progesterone, testosterone, and hemoglobin are not secreted by the Islets of Langerhans and do not play a role in blood sugar regulation.
