Nursing Elites

1. Which of the following blood tests should be performed before a blood transfusion?

• A. Prothrombin and coagulation time
• B. Blood typing and cross-matching
• C. Bleeding and clotting time
• D. Complete blood count (CBC) and electrolyte levels

Correct answer: B

Rationale: Before administering a blood transfusion, it is crucial to perform blood typing and cross-matching to ensure compatibility between the donor's blood and the recipient's blood. This process helps prevent adverse reactions such as transfusion reactions, which can be life-threatening. Prothrombin and coagulation time, bleeding and clotting time, as well as CBC and electrolyte levels are important tests in other clinical contexts, but for blood transfusions, blood typing and cross-matching are essential to ensure patient safety.

2. When providing mouth care to an unconscious client, what is the best position for the client?

• A. Fowler’s position
• B. Side-lying
• C. Supine
• D. Trendelenburg

Correct answer: B

Rationale: The best position for an unconscious client when providing mouth care is the side-lying position. This position helps prevent aspiration by allowing fluids to drain out of the mouth easily, reducing the risk of choking or aspiration pneumonia. Placing the client in a side-lying position also promotes comfort and safety during the procedure. The other options are not ideal for mouth care in an unconscious client: Fowler’s position may increase the risk of aspiration, the supine position can lead to aspiration as well, and Trendelenburg position is not recommended due to potential adverse effects on blood circulation and increased intracranial pressure.

3. During physical therapy, a client with Parkinson's disease makes the following statements. Which statement indicates the need for a referral to physical therapy?

• A. ''I have been experiencing more tremors in my left arm than before''
• B. ''I noticed that I am having a harder time holding on to my toothbrush''
• C. ''Lately, I feel like my feet are freezing up, as they are stuck to the ground''
• D. ''Sometimes, I feel I am making a chewing motion when I'm not eating''

Correct answer: C

Rationale: Feeling like the feet are freezing up and sticking to the ground is a common symptom of Parkinson's disease known as 'freezing of gait.' This symptom significantly impacts mobility and can be dangerous, indicating the need for specialized physical therapy interventions to address gait disturbances and improve mobility.

4. In the emergency department, a nurse is assessing a client involved in a motor vehicle crash. Findings include absent breath sounds in the left lower lobe with dyspnea, blood pressure 118/68 mm Hg, heart rate 124/min, respirations 38/min, temperature 38.6 C (101.4 F), and SaO2 92% on room air. What action should the nurse take first?

• A. Obtain a chest X-ray.
• B. Prepare for chest tube insertion.
• C. Administer oxygen via high-flow mask.
• D. Initiate IV access.

Correct answer: C

Rationale: In this scenario, the client is presenting with signs of respiratory distress, including absent breath sounds, dyspnea, and a low SaO2 level. The priority action should be to improve oxygenation by administering oxygen via a high-flow mask. This intervention aims to increase the oxygen supply to the client's lungs, helping to address the hypoxemia. Once oxygenation is optimized, further interventions, such as obtaining a chest X-ray, preparing for chest tube insertion, or initiating IV access, can be considered based on the client's condition and healthcare provider's orders.

5. What is the term for the body's ability to defend itself against specific invading agents such as bacteria, toxins, viruses, and foreign bodies?

• A. Hormones
• B. Secretion
• C. Immunity
• D. Glands

Correct answer: C

Rationale: The correct answer is C: Immunity. Immunity refers to the body's ability to protect itself against specific invading agents like bacteria, toxins, viruses, and foreign bodies by recognizing and destroying them. It is a crucial defense mechanism that helps maintain health and prevent infections and diseases. Choices A, B, and D are incorrect because hormones are chemical messengers, secretion is the process of releasing substances, and glands are organs that produce and release substances, none of which specifically relate to the body's defense against invading agents.
