How can preserving skin integrity impact the circular chain of infection?
- A. Host
- B. Reservoir
- C. Mode of transmission
- D. Portal of entry
Correct Answer: D
Rationale: Preserving skin integrity plays a key role in breaking the chain of infection by eliminating the portal of entry for pathogens. When the skin is intact, it acts as a natural barrier that prevents pathogens from entering the body. By maintaining skin integrity through proper hygiene and wound care, the risk of infection is significantly reduced, disrupting the cycle of infection transmission.

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.
Which of the following actions will most likely lead to a break in the sterile technique for respiratory isolation?
- A. Opening the patient's window to the outside environment
- B. Turning on the patient's room ventilator
- C. Opening the door of the patient's room leading into the hospital corridor
- D. Failing to wear gloves when administering a bed bath

Which of the following conditions may necessitate fluid restriction?
- A. Fever
- B. Chronic Obstructive Pulmonary Disease
- C. Renal Failure
- D. Dehydration
Correct Answer: C
Rationale: Renal failure often necessitates fluid restriction to prevent fluid overload. In renal failure, the kidneys are unable to effectively filter and excrete excess fluids, leading to fluid accumulation in the body. Restricting fluid intake helps manage this condition by preventing further fluid buildup and complications such as edema and electrolyte imbalances.
The nurse observes that Mr. Adams begins to have increased difficulty breathing. She elevates the head of the bed to the high Fowler position, which decreases his respiratory distress. The nurse documents this breathing as:
- A. Tachypnea
- B. Eupnea
- C. Orthopnea
- D. Hyperventilation
Correct Answer: C
Rationale: Orthopnea is a condition where a person experiences difficulty breathing when lying flat but finds relief when sitting up or standing. Elevating the head of the bed to the high Fowler position helps alleviate this symptom. Tachypnea refers to rapid breathing, eupnea is normal breathing, and hyperventilation is breathing excessively fast or deep.
