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 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.

Correct Answer is C
Explanation
Check fundal consistency and continue to monitor the lochial flow amount.
Choice A rationale:
Inserting an indwelling catheter to empty the bladder and contract the fundus is not the appropriate action for a sudden gush of vaginal blood and blood clots. The priority here is to assess the fundus, not intervene with an indwelling catheter. Catheterization may be necessary for other reasons, but not in this context.
Choice B rationale:
Returning the client to bed and maintaining bedrest until the lochial flow slows may be a reasonable initial response, but it is not the most appropriate action. The sudden gush of blood and presence of blood clots could be indicative of postpartum hemorrhage or retained placental tissue, which require prompt evaluation.
Choice C rationale:
Checking fundal consistency and continuing to monitor the lochial flow amount is the most appropriate action. The sudden gush of blood and clots suggest a possible uterine atony or retained products of conception. Assessing the fundal height and firmness helps identify if the uterus is contracting adequately, while monitoring the lochial flow amount can indicate ongoing bleeding.
Choice D rationale:
Massaging the fundus and avoiding direct pressure on the cesarean incision is not the recommended action in this situation. Massaging the fundus without assessing its consistency could worsen bleeding if there is uterine atony, and the client needs immediate evaluation and monitoring.
Correct Answer is A
Explanation
Glaucoma is a group of eye diseases that damage the optic nerve and cause vision loss. It is often associated with increased intraocular pressure, which can compress the nerve fibers and reduce blood flow to the retina. The most common type of glaucoma, open-angle glaucoma, causes gradual loss of peripheral vision.
The other options are not correct because:
A. Macular edema is a condition that causes swelling and fluid accumulation in the macula, the central part of the retina that is responsible for sharp and detailed vision. It can cause blurred or distorted vision, but it does not affect the optic nerve or the peripheral vision.
B. Cataract is a condition that causes clouding of the lens, which is the transparent structure that focuses light onto the retina. It can cause blurred, dim, or yellowed vision, but it does not affect the optic nerve or the intraocular pressure.
C. Diabetic retinopathy is a complication of diabetes that damages the blood vessels in the retina and causes bleeding, leakage, or scarring. It can cause blurred, fluctuating, or darkened vision, but it does not affect the optic nerve or the intraocular pressure.
