1. A nurse is reviewing the laboratory results of a client who has hypokalemia. Which of the following findings should the nurse expect?

Correct answer: B

Rationale: Flat T waves are a characteristic ECG finding in hypokalemia. Hypokalemia causes a decrease in serum potassium levels, leading to altered cardiac conduction. Flat T waves are associated with hypokalemia-induced cardiac dysrhythmias. Elevated ST segments are typically seen in conditions like myocardial infarction, not in hypokalemia. Bradycardia is not a typical manifestation of hypokalemia; instead, tachycardia may occur due to potassium imbalances affecting the heart's electrical activity.

2. A nurse is preparing to perform tracheostomy care for a client. Which of the following actions should the nurse take first?

Correct answer: B

Rationale: Suctioning the tracheostomy should be performed first to clear the airway of secretions and ensure proper oxygenation before proceeding with other care. This helps maintain a patent airway and prevent complications such as aspiration. Applying a sterile dressing, removing the inner cannula, or cleaning the stoma can follow after ensuring adequate airway clearance through suctioning.

3. Which lab value is critical for patients on warfarin therapy?

Correct answer: A

Rationale: The correct answer is to monitor INR levels for patients on warfarin therapy. INR monitoring is essential because it helps assess the clotting tendency of the blood and ensures that patients are within the therapeutic range to prevent both blood clots and excessive bleeding. Monitoring potassium levels (Choice B), sodium levels (Choice C), or platelet count (Choice D) is not specifically required for patients on warfarin therapy and does not directly impact the effectiveness or safety of the medication.

4. What is the initial step in managing a suspected pulmonary embolism in a patient?

Correct answer: A

Rationale: Administering oxygen is the initial step in managing a suspected pulmonary embolism. Oxygen therapy is crucial to improve oxygenation levels in the blood when there is a suspected blockage in the pulmonary artery. Administering anticoagulants, although important in the treatment of pulmonary embolism, is not the first step as ensuring adequate oxygen supply takes precedence. Repositioning the patient or administering IV fluids are not the primary interventions for a suspected pulmonary embolism and are not as essential as providing oxygen support.

5. A client is 4 hours postpartum. Which of the following interventions should be implemented to prevent postpartum hemorrhage?

Correct answer: D

Rationale: Administering methylergonovine intramuscularly helps contract the uterus, reducing the risk of postpartum hemorrhage. Monitoring for signs of infection (Choice A) is important but not directly related to preventing postpartum hemorrhage. Uterine massage (Choice B) is beneficial to prevent uterine atony, but methylergonovine is a more specific intervention to prevent hemorrhage. Applying ice packs to the perineum (Choice C) is helpful for perineal pain and swelling, not for preventing postpartum hemorrhage.
