The practical nurse (PN) is caring for a client with coronary artery disease who is admitted with intermittent chest pain. The admission laboratory results indicate elevations in troponin I and creatine phosphokinase myoglobin isoenzyme (CK-MB) levels.
What should the PN consider the most significant risk for this client on the second day of admission?
The lab results indicate myocardial damage, and the client is at risk for cardiac dysrhythmias
The client is at risk for pulmonary embolism, and lifestyle modifications need to be implemented.
The client is at risk for recurrent long-term angina pain and subsequent myocardial infarction (MI).
The lab results indicate risk factors for transient ischemic atack (TIA), and neurological vital signs should be monitored.
The Correct Answer is A
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 atack. 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:
- 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.
- 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.
- The lab results do not indicate risk factors for transient ischemic atack (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.

Correct Answer is B
Explanation
A) Incorrect - The APTT value being two times the control value indicates that the client's anticoagulation is within the therapeutic range. There is no need to increase the warfarin dose.
B) Correct - With the APTT value within the target range and the PT and INR values also normal, the nurse should continue the same dose of warfarin and withhold the heparin.
C) Incorrect - Decreasing the heparin dose is not indicated, as the client's APTT is already within the therapeutic range.
D) Incorrect - Increasing the heparin dose and decreasing the warfarin dose is not necessary, as the client's anticoagulation levels are appropriate.
Correct Answer is C
Explanation
A. Skipped eating lunch would more likely cause hypoglycemia rather than diabetic ketoacidosis (DKA). When a person with type 1 diabetes skips a meal but still takes insulin, blood glucose levels drop, leading to hypoglycemia, not the elevated glucose and ketone production seen in DKA.
B. Incorrectly administered too much insulin would also result in hypoglycemia rather than DKA. Administering excessive insulin causes blood glucose levels to fall too low, which does not trigger the fat breakdown and ketone production that characterize DKA.
C. Had a cold and ear infection for the past two days is the most likely cause of diabetic ketoacidosis. Illness and infection cause the body to release stress hormones such as cortisol and adrenaline, which increase blood glucose levels and counteract insulin. In type 1 diabetes, insufficient insulin leads to hyperglycemia, fat breakdown for energy, and the production of ketones, resulting in DKA.
D. Ate an extra peanut butter sandwich before gym class would not cause DKA. Consuming extra food may raise blood glucose temporarily, but it would not lead to the severe insulin deficiency and ketone production seen in DKA, especially if the adolescent took insulin as prescribed.
