The healthcare provider is assessing a client before surgery. Which assessments contraindicate the client from having surgery as scheduled? (Select one that does not apply.)
- A. Potassium level of 2.8 mEq/L
- B. International normalized ratio (INR) of 4
- C. Prothrombin time (PT) of 30 seconds
- D. Positive pregnancy test
Correct Answer: C
Rationale: The correct answer is C: Prothrombin time (PT) of 30 seconds. A low potassium level (choice A) and an elevated INR (choice B) indicate potential bleeding risks during surgery. A positive pregnancy test (choice D) in a female client can lead to complications during surgery. However, a Prothrombin time of 30 seconds is within the normal range and does not contraindicate the client from having surgery as scheduled.

To obtain a sterile urine specimen from a client with a Foley catheter, the nurse begins by applying a clamp to the drainage tubing distal to the injection port. What does the nurse do next?
- A. Clamp another section of the tube to create a fixed sample section for retrieval.
- B. Insert a syringe into the injection port and aspirate the quantity of urine required.
- C. Clean the injection port cap of the drainage tubing with povidone-iodine solution.
- D. Withdraw 10 mL of urine and discard it; then withdraw 10 mL more for the sample.
Correct Answer: C
Rationale: After clamping the drainage tubing, the next step in obtaining a sterile urine specimen from a client with a Foley catheter is to clean the injection port cap of the drainage tubing with povidone-iodine solution. This cleaning step helps prevent contamination of the urine sample. Clamping another section of the tube isn't necessary and may not be a standard practice. Inserting a syringe into the injection port to aspirate urine isn't the correct step at this point. Withdrawing 10 mL of urine and discarding it before collecting the sample isn't appropriate and may lead to an inaccurate sample.
A client who has a head injury is transported to the emergency department. Which assessment does the emergency department nurse perform immediately?
- A. Pupil response
- B. Motor function
- C. Respiratory status
- D. Short-term memory
Correct Answer: C
Rationale: In a client with a head injury, assessing the respiratory status is the priority as airway and breathing are essential for life. Immediate attention to respiratory status is crucial to ensure adequate oxygenation. While assessing pupil response and motor function are also important in head injuries, ensuring the client's ability to breathe takes precedence. Short-term memory assessment is not a priority in the emergent phase of care for a client with a head injury.
The nurse assesses distended neck veins in a client sitting in a chair to eat. What intervention is the nurse's priority?
- A. Document the observation in the chart.
- B. Measure urine specific gravity and volume.
- C. Assess the pulse and blood pressure.
- D. Assess the client's deep tendon reflexes.
Correct Answer: C
Rationale: The correct answer is to assess the pulse and blood pressure. Distended neck veins can indicate fluid volume overload or heart failure, which can lead to hemodynamic instability. Assessing the pulse and blood pressure will provide immediate information on the client's cardiovascular status. Documenting the observation in the chart (choice A) is important but not the priority when immediate assessment is needed. Measuring urine specific gravity and volume (choice B) is important for assessing renal function but is not the priority in this situation. Assessing the client's deep tendon reflexes (choice D) is not relevant to addressing distended neck veins in a client sitting to eat.
A nurse is caring for several clients with dehydration. The nurse assesses the client with which finding as needing oxygen therapy?
- A. Tenting of skin on the back of the hand
- B. Increased urine osmolarity
- C. Weight loss of 10 pounds
- D. Pulse rate of 115 beats/min
Correct Answer: D
Rationale: The correct answer is the pulse rate of 115 beats/min. A rapid pulse rate is a sign of compensatory mechanisms in response to dehydration, indicating that the body is trying to deliver oxygen more efficiently. Oxygen therapy may be needed to support the increased oxygen demand. Tenting of skin on the back of the hand is a classic sign of dehydration due to decreased skin turgor. Increased urine osmolarity and weight loss are also indicators of dehydration, but they do not directly suggest a need for oxygen therapy.
The nurse is caring for a hospitalized client who has AIDS and is severely immune compromised. Which
interventions are used to help prevent infection in this client? (Select one that doesn't apply.)
- A. Use sterile gloves and gowns whenever the nursing staff is in contact with the client.
- B. Keep a blood pressure cuff, thermometer, and stethoscope in the client's room for his or her
use only - C. Request that the family take home the fresh flowers that are at the client's bedside
- D. Assist the client with meticulous oral care after meals and at bedtime.
Correct Answer: A
