A client is receiving a secondary IV infusion of azithromycin 500 mg in 500 mL of normal saline (NS) to be infused over 2 hours. The IV administration set delivers 20 gtt/mL. How many gtt/min should the nurse regulate the infusion? (Enter numerical value only. If rounding is required, round to the nearest whole number.)

Rationale for Correct Choices:

• Myocardial infarct (MI): The client presents with chest pain described as pressure and tightness, which worsens over time. The ECG shows ST depression, a common sign of ischemia. This combined with the risk factors and vital signs support myocardial infarction.
• Prepare client for possible percutaneous coronary intervention: If a myocardial infarction is suspected, preparing the client for PCI is critical. PCI is used to treat blockages in the coronary arteries, which is essential for restoring blood flow and minimizing myocardial damage.
• Educate on nitroglycerin administration: Nitroglycerin helps alleviate chest pain by relaxing coronary arteries, reducing heart workload, and improving blood flow. It is used in MI management to relieve symptoms and reduce ischemia.
• Electrocardiogram (ECG): Continuous ECG monitoring is essential to assess the progression of any arrhythmias or ischemic changes, which are common during an MI. It allows real-time identification of worsening conditions.
• Chest pain: Monitoring chest pain closely helps evaluate the effectiveness of treatment and determine whether ischemia persists or resolves. Pain relief indicates that interventions are successful.

Rationale for Incorrect Choices:

• Atrial fibrillation: While atrial fibrillation can cause chest discomfort, the patient’s clinical presentation, including ECG findings and risk factors, is more consistent with an MI. Atrial fibrillation usually presents with irregular heartbeats rather than persistent chest pressure.
• Congestive heart failure: The current presentation, including chest pain, ECG changes, and pain unrelieved by rest, points to a myocardial infarction rather than congestive heart failure. There are no signs of fluid overload or symptoms associated with heart failure in this scenario.
• New onset angina: While the client may experience angina, the unrelieved chest pain lasting for over 30 minutes and the severity of the symptoms suggest a myocardial infarction rather than just new onset angina, which typically resolves with rest.
• Begin chest compressions: Chest compressions are necessary only in cases of cardiac arrest. While this client is experiencing chest pain and signs of an MI, there is no indication of cardiac arrest, so chest compressions are not appropriate at this point.
• Consult physical therapy: Physical therapy is not immediately needed for the acute management of myocardial infarction. The priority is stabilizing the patient's cardiac status and addressing the ischemia, not physical rehabilitation.
• Conduct a nutritional history: While a nutritional history is important for long-term heart disease management, it is not an immediate concern during an acute MI episode. The focus should be on stabilizing the patient and addressing the immediate cardiovascular issues.

• Lung sounds: Lung sounds are not directly relevant to this patient's current condition. While they may be important for detecting complications like pulmonary edema, they are not a priority when assessing for an acute MI.
• Pedal pulses: Pedal pulses can be useful in assessing peripheral circulation but are not a priority in the management of MI unless signs of shock or poor circulation are noted.
• Intake and output: While monitoring intake and output is important for fluid balance, it is not the immediate focus for managing this patient’s acute MI. The focus should be on cardiac parameters and symptom relief, such as monitoring chest pain and ECG changes.

A. Urinate at a specified time, discard this urine, and collect all subsequent urine during the next 24 hours: Discarding the first void ensures the collection begins with an empty bladder, and all urine afterward is included for accurate measurement.

B. Urinate immediately into a urinal, and the lab will collect the specimen every 6 hours, for the next 24 hours: This describes timed urine sampling, not a continuous 24-hour collection required for creatinine clearance.

C. For the next 24 hours, notify nurse when the bladder is full, and the nurse will collect catheterized specimens: Routine creatinine clearance testing does not require catheterization unless the client is already catheterized.

D. Cleanse around the meatus, discard first portion of voiding, and collect the rest in a sterile bottle: This describes a midstream or clean-catch technique, typically used for urine cultures, not 24-hour collections.
