108. Constant monitoring of cardiac function, a requirement for vascular surgery is effected by the use of a

Doppler

Swan-Ganz

Greenfield

Fogarty

The Swan-Ganz catheter is commonly used in vascular surgery to continuously monitor cardiac function. It is a specialized catheter that is inserted into the pulmonary artery, allowing for accurate measurements of cardiac output, pulmonary artery pressure, and other hemodynamic parameters. This information is crucial during surgery as it helps the medical team assess the patient's cardiovascular status and make necessary interventions if needed. The Doppler, Greenfield, and Fogarty options are not specifically designed for continuous cardiac monitoring in vascular surgery.

109. Neo-Synephrine is

Miotic

Retrobulbar blocker

Phacoemulsifier

Mydriatic

Neo-Synephrine is a medication that is classified as a mydriatic. Mydriatics are drugs that cause dilation of the pupil. Neo-Synephrine is commonly used in ophthalmology to dilate the pupil for various diagnostic and surgical procedures. It works by stimulating the dilator muscle of the iris, causing the pupil to enlarge. This allows for better visualization of the structures within the eye during examinations or surgeries.

110. Each of the following treats glaucoma EXCEPT

Trephining

Laser trabeculoplasty

Keratoplasty

Iridectomy

Keratoplasty is a surgical procedure that involves replacing the cornea with a healthy cornea from a donor. Glaucoma is a condition that affects the optic nerve and is usually caused by increased pressure within the eye. Treatments for glaucoma aim to reduce this pressure and prevent further damage to the optic nerve. Trephining, laser trabeculoplasty, and iridectomy are all treatments that can help lower intraocular pressure and manage glaucoma. However, keratoplasty is not directly related to treating glaucoma as it focuses on replacing the cornea rather than addressing the underlying pressure issue.

111. An intravenous agent used for anesthesia induction is

Lidocaine

Fluothane

Sodium pentothal

Demerol

Sodium pentothal is commonly used as an intravenous agent for anesthesia induction. It is a short-acting barbiturate that produces rapid unconsciousness and is often preferred for its quick onset and smooth induction. Lidocaine is a local anesthetic and not typically used for anesthesia induction. Fluothane is a volatile inhalation anesthetic, not an intravenous agent. Demerol is an opioid analgesic, not an anesthesia induction agent. Therefore, sodium pentothal is the correct answer.

112. Which of the following statements is a contraindication to intraocular lens (IOL) implant?

Elderly patient with bilaterla cataracts

Children with traumatic cataracts

Patients with occupational vision requirements

Children with congenital cataracts

Children with congenital cataracts are a contraindication to intraocular lens (IOL) implant because their eyes are still developing and growing. Implanting an IOL in a child with congenital cataracts can interfere with the natural development of the eye and may cause complications. It is generally recommended to wait until the child's eyes have fully developed before considering an IOL implant.

113. Pilocarpine is used to

Dilate the pupil

Constrict the pupil

Keep the eye moist

Reduce inflammation

Pilocarpine is a medication that is used to constrict the pupil. Constriction of the pupil is known as miosis, and it is achieved by stimulating the muscles in the iris to contract. Pilocarpine acts on the muscarinic receptors in the eye, causing the circular muscles of the iris to contract, resulting in a smaller pupil size. This can be beneficial in certain eye conditions, such as glaucoma, where reducing the size of the pupil can help to improve the outflow of fluid from the eye and lower intraocular pressure.

114. Transcutaneous electric nerve stimulation (TENS) would be utilized for

Urinary calculi

Soft tissue allograft

Dressing for burns

Antiembolitic effort

TENS, or transcutaneous electric nerve stimulation, would be utilized for urinary calculi. This is because TENS therapy involves the use of low-voltage electrical currents to provide pain relief. Urinary calculi, also known as kidney stones, can cause severe pain, and TENS therapy can help to alleviate this pain by stimulating the nerves and blocking pain signals. Therefore, TENS would be an appropriate treatment option for urinary calculi.
