The nurse is reviewing the laboratory results of a client scheduled for surgery. Which of the following should be reported to the primary health care provider (PHCP)?
- A. Glycosylated hemoglobin (HbA1c) of 7.2% [5.7-6.4%]
- B. International Normalized Ratio (INR) of 3.5 [0.9-1.2 seconds]
- C. Hematocrit (Hct) of 42% [Male: 42-52% Female: 37-47%]
- D. Blood urea nitrogen (BUN) level of 5 [10-20 mg/dL]
Correct Answer: B
Rationale: An INR of 3.5 indicates a high bleeding risk, critical for surgical safety, and must be reported to the PHCP. Elevated HbA1c, normal hematocrit, and low BUN are less urgent but may still require attention.

The nurse is planning care for a client diagnosed with Mycoplasma pneumonia. The nurse should plan to
- A. place the client in a private room with negative airflow.
- B. wear a surgical mask within 3 feet of the client.
- C. wear gloves when in contact with the client.
- D. provide disposable meal trays and utensils.

The nurse is caring for a client who has pulmonary tuberculosis (TB). Which infection control measure should the nurse implement?
- A. Restrict visitors who are pregnant
- B. Remove any portable fans in the room
- C. Wear a dosimeter badge during client care
- D. Place the client further away from the nursing station
Correct Answer: B
Rationale: Portable fans can spread TB bacilli, so they should be removed. Pregnant visitors are not specifically restricted, dosimeters are for radiation, and room placement is less critical.
The nurse is discussing negligence with a new nurse. Which of the following situations can the nurse use as an example of negligence?
- A. The Unlicensed Assistive Personnel (UAP) fills a water basin with warm water while the client with depression combs their hair.
- B. A nurse transcribes a new medication order: Cholestyramine powder 2 oz bid with wet food or one full glass of water.
- C. The nurse first checks the distal pulses of a client's legs two hours after they have returned from a cardiac catheterization.
- D. The nurse observes a UAP enter the room of a client on contact precautions wearing gloves and a gown.
Correct Answer: NONE
Rationale: None of the options describe negligence, as all reflect appropriate actions or minor procedural variations without harm.
The nurse is preparing to obtain a wound culture on an infected leg ulcer. Before swabbing the wound to obtain the culture, the nurse should
- A. Clean the wound with sterile saline.
- B. Pat dry the wound with gauze.
- C. Irrigate the wound with hydrogen peroxide.
- D. Don sterile gloves
Correct Answer: A
Rationale: Cleaning with sterile saline removes debris, ensuring an accurate culture. Drying, using peroxide, or sterile gloves (clean gloves suffice) are not appropriate.
The nurse is caring for a postoperative client who is ordered to use an incentive spirometer. The nurse understands that this device will help prevent which complication?
- A. venous thromboembolism
- B. obstructive sleep apnea
- C. hypostatic pneumonia
- D. aspiration pneumonia
Correct Answer: C
Rationale: Incentive spirometry promotes lung expansion and prevents atelectasis, reducing the risk of hypostatic pneumonia in postoperative clients with limited mobility. It does not directly prevent venous thromboembolism, obstructive sleep apnea, or aspiration pneumonia.
