Nursing Elites

1. Which of the following tests would MOST LIKELY be performed on a patient who is being monitored for coagulation therapy?

• A. PT/INR
• B. CBC
• C. PTT
• D. WBC

Correct answer: A

Rationale: The correct answer is A: PT/INR. Prothrombin times (PT/INR) are commonly used to monitor patients on Coumadin (warfarin) therapy, an anticoagulant that slows the blood's ability to clot. Monitoring PT/INR levels helps ensure the patient is receiving the appropriate dosage of Coumadin. Choice B, CBC (Complete Blood Count), is a general test that provides information on red blood cells, white blood cells, and platelets but is not specific to monitoring coagulation therapy. Choice C, PTT (Partial Thromboplastin Time), is another coagulation test but is not as commonly used for monitoring Coumadin therapy. Choice D, WBC (White Blood Cell count), is unrelated to monitoring coagulation therapy and is used to assess immune system function.

2. Which of these statements is true regarding the use of Standard Precautions in the healthcare setting?

• A. Standard Precautions apply to all body fluids, except sweat.
• B. Alcohol-based hand rub should be used if hands are not visibly dirty.
• C. Standard Precautions are intended for use with all patients, regardless of their risk or presumed infection status.
• D. Standard Precautions are to be used only when non-intact skin, excretions containing visible blood, or expected contact with mucous membranes are present.

Correct answer: C

Rationale: Standard Precautions are designed to reduce the risk for transmission of microorganisms from both recognized and unrecognized sources. They are intended for use with all patients, regardless of their risk or presumed infection status. Standard Precautions apply to all body fluids, secretions, and excretions except sweat - whether or not they contain visible blood, non-intact skin, or mucous membranes. Hands should be washed with soap and water if visibly soiled with blood or body fluids. Alcohol-based hand rubs can be used if hands are not visibly soiled. Choice A is incorrect because Standard Precautions apply to all body fluids, secretions, and excretions except sweat. Choice B is incorrect because alcohol-based hand rub should be used when hands are not visibly dirty. Choice D is incorrect because Standard Precautions are not limited to situations involving non-intact skin, excretions with visible blood, or expected mucous membrane contact.

3. The nurse is preparing to perform a physical assessment. The correct action by the nurse is reflected by which statement?

• A. Performs the examination from both sides of the bed.
• B. Examines tender or painful areas last to help relieve the patient's anxiety.
• C. Follows a flexible examination sequence, considering the patient's age and condition.
• D. Organizes the assessment to ensure that the patient does not change positions too often.

Correct answer: D

Rationale: The nurse should organize the assessment to minimize the patient's need to change positions frequently, ensuring efficiency and comfort. It is essential to perform the examination from both sides of the bed to facilitate a comprehensive assessment. Examining tender or painful areas last can help reduce patient discomfort and anxiety. The examination sequence should be flexible, taking into account the patient's age, condition, and specific needs. This approach allows for a tailored and patient-centered assessment, optimizing the quality of care provided.

4. A child is admitted to the hospital several days after stepping on a sharp object that punctured her athletic shoe and entered the flesh of her foot. The physician is concerned about osteomyelitis and has ordered parenteral antibiotics. Which of the following actions is done immediately before the antibiotic is started?

• A. The admission orders are written.
• B. A blood culture is drawn.
• C. A complete blood count with differential is drawn.
• D. The parents arrive.

Correct answer: B

Rationale: Before starting antibiotics, a blood culture should be drawn to identify the causative organism. This step is crucial as antibiotics may interfere with the identification process. Drawing a complete blood count with differential or writing admission orders are important steps in patient care but are not as critical as obtaining a blood culture to guide appropriate antibiotic therapy. The arrival of the parents is not directly related to the immediate action required before starting antibiotics in this scenario.

5. When performing an EKG, the patient starts to laugh out of feelings of anxiety. What would you expect the EKG to show? (Choose the BEST answer.)

• A. Increased pulse rate, normal EKG
• B. Decreased pulse rate, abnormal EKG
• C. Tachycardia, poor EKG graph
• D. Bradycardia, poor EKG graph

Correct answer: C

Rationale: When a patient laughs due to anxiety during an EKG, it is likely to cause tachycardia, which is a rapid heart rate. This increased heart rate can lead to poor EKG graph quality as the electrical signals from large moving muscles can interfere with data collection from the chest leads. Therefore, in this scenario, the EKG is expected to show tachycardia with poor graph quality. Choices A, B, and D are incorrect because a patient laughing out of anxiety is more likely to result in an increased pulse rate (tachycardia) rather than a decreased pulse rate (bradycardia) or a normal EKG.
