Nursing Elites

1. In which of the following organs does the exchange of gases take place?

• A. Kidneys
• B. Lungs
• C. Liver
• D. Heart

Correct answer: B

Rationale: The exchange of gases, specifically oxygen and carbon dioxide, occurs in the lungs. In the lungs, oxygen from the air we breathe enters the bloodstream, while carbon dioxide is removed from the bloodstream and exhaled. This process is essential for respiration and supplying the body with oxygen for energy production. The kidneys filter waste from the blood to produce urine and regulate fluid balance (Choice A). The liver is involved in detoxification, protein synthesis, and producing bile (Choice C). The heart is responsible for pumping blood throughout the body to deliver oxygen and nutrients (Choice D).

2. The physician orders a maintenance dose of 5,000 units of subcutaneous heparin (an anticoagulant) daily. Nursing responsibilities for Mrs. Mitchell now include:

• A. Reviewing daily activated partial thromboplastin time (APTT) and prothrombin time.
• B. Reporting an APTT above 45 seconds to the physician
• C. Assessing the patient for signs and symptoms of frank and occult bleeding
• D. All of the above

Correct answer: D

Rationale: The correct answer is D. When a physician orders a maintenance dose of subcutaneous heparin, nursing responsibilities include reviewing daily activated partial thromboplastin time (APTT) and prothrombin time to monitor the patient's coagulation status, reporting an APTT above 45 seconds to the physician as it may indicate a risk of bleeding, and assessing the patient for signs and symptoms of frank and occult bleeding, which are potential adverse effects of anticoagulant therapy. Therefore, all the options listed are essential nursing responsibilities when a patient is on subcutaneous heparin therapy.

3. Which of the following procedures always requires surgical asepsis?

• A. Vaginal instillation of conjugated estrogen
• B. Urinary catheterization
• C. Nasogastric tube insertion
• D. Colostomy irrigation

Correct answer: B

Rationale: Surgical asepsis, which involves maintaining a sterile field and preventing contamination in a surgical setting, is required for urinary catheterization as it involves entering a sterile body cavity. Vaginal instillation of conjugated estrogen, nasogastric tube insertion, and colostomy irrigation do not always require surgical asepsis as they involve different levels of sterility and infection control measures.

4. Which of the following techniques involves the sense of sight?

• A. Inspection
• B. Palpation
• C. Percussion
• D. Auscultation

Correct answer: A

Rationale: The correct answer is Inspection (Choice A). Inspection is a technique that involves observing the patient using the sense of sight. During inspection, a healthcare provider visually examines the patient for any abnormalities, changes, or specific signs that may help in diagnosing a condition. Palpation (Choice B) involves using the sense of touch to feel for abnormalities. Percussion (Choice C) involves tapping the body to produce sounds that can help identify the underlying structures. Auscultation (Choice D) involves listening to sounds produced by the body, typically using a stethoscope. Therefore, in this context, the technique that specifically involves the sense of sight is Inspection.

5. A nurse obtained a client’s pulse and found the rate to be above normal. The nurse documents this finding as:

• A. Tachypnea
• B. Hyperpyrexia
• C. Arrhythmia
• D. Tachycardia

Correct answer: D

Rationale: When a nurse finds a client's pulse rate to be above normal, it is documented as tachycardia. Tachycardia specifically refers to an elevated heart rate, while tachypnea is rapid breathing, hyperpyrexia is high fever, and arrhythmia is an irregular heartbeat. Therefore, the correct term to describe an above-normal pulse rate is tachycardia.
