Correct Answer: A

Rationale: The ECG strip shows sinus bradycardia, which is common in clients with an inferior wall MI. This rhythm can lead to decreased perfusion due to bradycardia and blocks. The most crucial initial action for the nurse is to assess the client's hemodynamic status, including blood pressure and level of consciousness. This assessment will help determine the immediate needs of the client. Calling the health care provider or the Rapid Response Team, obtaining a permit for a pacemaker insertion, or preparing to administer antidysrhythmic medication may be necessary based on the assessment findings, but the priority is to evaluate the client's current condition first.

Correct Answer: D

Rationale: After a total hip replacement, clients should avoid bending at the waist past 90 degrees for at least 6 weeks to prevent dislocation of the hip prosthesis. Bending down to tie shoes involves significant hip flexion and should be avoided during the initial postoperative period to ensure proper healing and reduce the risk of complications.

Correct Answer: C

Rationale: Assessing for chest pain is crucial in post-MI clients as it can indicate complications such as reinfarction or ischemia.

Correct Answer: B

Rationale: During an acute asthma attack, the priority is to quickly relieve bronchospasm and improve breathing. Short-acting beta agonists, like albuterol, are the first-line medications as they rapidly relax bronchial muscles, providing immediate relief. Oral corticosteroids are used as adjunct therapy to reduce airway inflammation over time, while leukotriene receptor antagonists and long-acting beta agonists are not appropriate for immediate relief during an acute attack.

Correct Answer: A

Rationale: The sound described is an S3 heart sound, which can indicate heart failure. The next appropriate action for the provider is to listen to the client's lung sounds. Lung sounds can provide additional information about the client's condition, especially when abnormal heart sounds are present. Calling the Rapid Response Team is not warranted based solely on the heart sound assessment. Having the client sit upright is not directly related to addressing the abnormal heart sound.
