Correct Answer: A

Rationale: The correct answer is to check the patient's heart rate before administering digoxin. Digoxin is a medication that primarily affects cardiac function. Monitoring the heart rate is crucial because digoxin can cause arrhythmias or worsen existing heart rhythm abnormalities. Assessing blood pressure may also be important but is secondary to evaluating the heart rate when administering digoxin. Ensuring the patient has eaten before administration is not directly related to the safe administration of digoxin. Monitoring the patient's weight is not a priority action before administering digoxin.

Correct Answer: A

Rationale: The correct answer is A: Sterilizing contaminated items. Maintaining medical asepsis involves ensuring that items are free of microorganisms to prevent infections. Sterilizing contaminated items is a crucial step in this process as it eliminates all microorganisms, including spores. Choices B, C, and D do not directly address the process of reducing and preventing the spread of microorganisms. While routinely cleaning the hospital environment is important for cleanliness, it does not guarantee the elimination of all microorganisms. Reapplying a sterile dressing and applying a sterile gown and gloves are specific actions related to personal protective equipment and wound care, not the general maintenance of medical asepsis.

Correct Answer: A

Rationale: The correct answer is to administer a bronchodilator as prescribed. This intervention is the priority for a patient with asthma experiencing shortness of breath as it helps relax the airways, making breathing easier. Encouraging the use of an incentive spirometer (Choice B) is beneficial for lung expansion but not the priority in this acute situation. Placing the patient in a high Fowler's position (Choice C) can also help with breathing but is not as immediate as administering a bronchodilator. While monitoring the patient's oxygen saturation closely (Choice D) is important, the immediate action to address the breathing difficulty is administering a bronchodilator.

Correct Answer: D

Rationale: The correct action for the nurse to take first is to report the behavior to the supervisor. Proper hand hygiene is essential in preventing the spread of infections in healthcare settings. By reporting the observed behavior to the supervisor, the nurse is prioritizing patient safety and promoting a culture of accountability. Ignoring the behavior (Choice A) can put patients at risk, discussing it with other colleagues (Choice B) may not address the issue effectively, and confronting the colleague directly (Choice C) might not be the most appropriate initial step and could lead to conflicts rather than a constructive resolution.

Correct Answer: A

Rationale: The correct answer is to suction the tracheostomy to maintain a patent airway. After a tracheostomy, the priority intervention is to ensure a clear airway to prevent respiratory distress. Administering pain medication, changing the tracheostomy dressing, and monitoring oxygen saturation are important but are secondary to maintaining a patent airway in a patient who has just undergone a tracheostomy.
