The practical nurse (PN) is completing a focused assessment on a client who is prescribed oxygen at 3 liters per minute by nasal cannula. Which assessment finding by the PN requires immediate action?

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:

1. 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.
2. 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.
3. 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.

A) Incorrect - Hyperglycemia typically does not lead to weight loss. In fact, it can result in weight gain due to the body's inability to properly use glucose for energy.

B) Correct - Hyperglycemia can lead to an increased sensation of hunger as the body's cells are not effectively receiving the glucose they need for energy, causing the person to feel hungry.
C) Incorrect - Cool and clammy skin are not typical symptoms of hyperglycemia. Hyperglycemia can lead to dry skin, but it does not cause cool and clammy skin.
D) Correct - Hyperglycemia often leads to increased thirst and urination. Excess glucose in the blood can cause the kidneys to work harder to filter and eliminate the glucose, leading to increased fluid intake and subsequently increased urination.
E) Hyperglycemia can cause dehydration, leading to dry, flushed skin and sometimes headaches due to electrolyte imbalances and reduced blood flow to the brain.
