A client in the psychiatric unit's dayroom is becoming agitated, talking incessantly, and starting to yell and swear at the other clients.

Which action should the practical nurse (PN) implement first?

Troponin I and CK-MB are cardiac enzymes that are released into the bloodstream when the heart muscle is injured or necrotic. Elevated levels of these enzymes indicate that the client has suffered a myocardial infarction (MI) or heart attack. The damaged heart tissue can impair the electrical conduction system of the heart and cause abnormal heart rhythms or dysrhythmias, which can be life-threatening. The PN should monitor the client's cardiac status closely and report any changes to the charge nurse.

The other options are not correct because:

B. The client is not at risk for pulmonary embolism, which is a blockage of a pulmonary artery by a blood clot or other material. Pulmonary embolism does not cause elevated cardiac enzymes, but it can cause chest pain, shortness of breath, and hypoxia.

C. The client is not at risk for recurrent long-term angina pain, which is chest pain caused by reduced blood flow to the heart muscle due to narrowed or blocked coronary arteries. Angina pain does not cause elevated cardiac enzymes, but it can be a warning sign of an impending MI.

D. The lab results do not indicate risk factors for transient ischemic attack (TIA), which is a temporary interruption of blood flow to a part of the brain due to a clot or plaque. TIA does not cause elevated cardiac enzymes, but it can cause neurological symptoms such as weakness, numbness, or speech difficulties.

Digoxin is a medication used to treat various heart conditions, such as abnormal heart rhythms and heart failure.It works by improving the strength and efficiency of the heart, or by controlling the rate and rhythm of the heartbeat.

One of the important things to monitor when giving digoxin to an infant is the pulse rate. Digoxin can lower the heart rate, which can be dangerous if it becomes too slow.Therefore, the pulse rate should be checked for one full minute before administering digoxin, and the medication should be held if the pulse rate is below 90 beats per minute (bpm) for an infant.

In this case, the infant’s heart rate is 120 bpm, which is within the normal range for a 2-month-old. Therefore, the correct action for the PN to take is to administer the medication and document the heart rate. This is optionbin the list of choices. Optionais incorrect because there is no need to hold the medication or recheck the heart rate in one hour. Optioncis incorrect because there is no need to alert the charge nurse unless there is a problem with the infant’s condition or the medication. Optiondis incorrect because holding the medication and documenting cardiac assessment is not appropriate for a normal heart rate.
