When examining the eye, where will the nurse most likely find signs of liver disease?

Rationale for Correct Choices

• Cardiac Arrest: The client presents with the clinical triad of cardiac arrest: unresponsiveness, apnea (not breathing), and pulselessness. The sudden collapse during physical exertion in a patient with cardiovascular risk factors (hypertension, high cholesterol) is highly suggestive of a primary cardiac event.
• Begin CPR: High-quality chest compressions are the immediate priority to maintain systemic perfusion and provide blood flow to the heart and brain until advanced life support or defibrillation is available.
• Send someone to retrieve the AED: Early defibrillation is the most critical link in the "Chain of Survival" for witnessed cardiac arrest, as the most common cause in this setting is a shockable rhythm like Ventricular Fibrillation (VF).
• Palpate Pulse: Regular pulse checks (limited to 10 seconds) during rhythm analysis are necessary to determine if Return of Spontaneous Circulation (ROSC) has occurred.
• Compression Effectiveness: Monitoring the depth (at least 2 inches), rate (100–120/min), and allowing full chest recoil is vital to ensure that the manual pumping of the heart is actually circulating blood.

Rationale for Incorrect Choices

• Hypoglycemia: While it can cause loss of consciousness, it does not typically cause a sudden "clutching of the chest" and immediate loss of a pulse in a witnessed collapse.
• MVC Trauma: There is no evidence of a Motor Vehicle Collision; this was an atraumatic medical collapse during exercise.
• Narcotic Overdose: Typically presents with pinpoint pupils and a slow, shallow respiratory rate (respiratory depression) rather than sudden-onset pulselessness during physical activity.
• Administer ordered Pain medication for Angina: The patient is pulseless and unresponsive; oral or standard IV pain medications are contraindicated and useless in a state of circulatory collapse.
• Apply Non-Rebreather: Oxygen therapy via mask is ineffective if the patient is not breathing and has no circulation to transport the oxygen. The priority is ventilation (via Bag-Valve-Mask) and compressions.
• Apply Icepacks to Reduce Inflammation: This is irrelevant in a life-threatening cardiac emergency.
• Administer D50W 12.5mg IVP: This is the treatment for hypoglycemia; there is no evidence the patient is hypoglycemic, and CPR/defibrillation must come first.
• Assess for power of attorney / Monitor I&Os / Pain Score: These are non-urgent or impossible tasks (the patient cannot report pain) during an active resuscitation.
• Examine Extremities for Fall Injuries: While secondary injuries can occur, checking for broken bones is a lower priority than restoring a pulse (the "C-A-B" sequence).

Acute angle-closure glaucoma is ophthalmic emergency due to sudden trabecular meshwork obstruction causing elevated intraocular pressure, optic nerve ischemia, presenting with severe ocular pain, nausea, vomiting, glaucoma, intraocular pressure, optic nerve, halos.

Rationale:

A. Cranial nerve III assessment evaluates ocular motor function involvement assessment. Cranial nerve III controls most extraocular eye movements functionally. Oculomotor dysfunction presents with ptosis diplopia not acute pain state. Symptoms here indicate intraocular pressure emergency not nerve palsy process.

B. Acute angle-closure glaucoma is ophthalmic emergency from sudden trabecular blockage causing high intraocular pressure. acute angle-closure presents with severe eye pain, halos, nausea. emergency referral is required to prevent vision loss. Delay results in optic nerve ischemia and blindness state.

C. Corneal light reflex assesses ocular alignment via cranial nerve II and III pathways. corneal reflex tests blink response to corneal stimulation touch. alignment abnormalities indicate strabismus not acute ocular pressure emergency. Symptoms require urgent referral not reflex testing process state.

D. Presbyopia is age-related loss of lens accommodation due to decreased elasticity causing near vision difficulty. presbyopia develops gradually after age 40 years. age-related changes do not cause eye pain or halos. Symptoms here indicate acute pathology not refractive aging state.
