10 Random Questions

When used for irrigation during transurethral resection of the prostate, glycine 1.5% is associated with each of the following EXCEPT

(A) hemolysis
(B) hyperammonemia
(C) cerebral edema
(D) hypofibrinogencmia
(E) visual disturbances

ADVANCED General

In a patient who has undergone cholecystectomy, which of the following is the most likely pulmonary effect of systemically administered opioids?

(A) Decreased Qs/Qt
(B) Decreased dead space
(C) Restored vital capacity
(D) Restored functional residual capacity
(E) Shift of the carbon dioxide response curve to the right

BASIC Pharmacology & Pharmacokinetics

A 39-year-old patient with insulin-dependent diabetes mellitus receives thiopental 250 mg and succinylcholine 80 mg and is ventilated with 0.75% isoflurane in oxygen. Arterial pressure decreases abruptly from 140/100 to 80/50 mmHg while heart rate remains unchanged at 70 bpm. Failure of heart rate to increase most likely results from

(A) acute hypoglycemia
(B) autonomic neuropathy
(C) depression of sinus node function by thiopental
(D) depression of the baroreflex response by isoflurane
(E) ganglionic stimulation by succinylcholine

ADVANCED General

When succinylcholine is administered intravenously to infants, intragastric pressure

(A) is usually unchanged
(B) increases to a peak of 30 cmH20 within two minutes
(C) increases because of abdominal muscle fasciculations
(D) increases because of an acetylcholine-like effect on the vagus nerve
(E) peaks and subsides within five minutes

ADVANCED Pharmacology & Pharmacokinetics Pediatric

Each of the following increases arterial to end-tidal carbon dioxide tension difference EXCEPT

(A) addition of positive-end expiratory pressure
(B) deliberate hypotension
(C) endobronchial intubation
(D) hypovolemia
(E) pulmonary embolism

BASIC Respiratory & Critical Care

Compared with adults, neonates are more likely to become hypoxemic following anesthesia and extubation because of a relatively

(A) higher rate of oxygen consumption
(B) greater sensitivity to neuromuscular blockade
(C) larger Vd/Vt ratio
(D) lower blood pressure
(E) smaller functional residual capacity

ADVANCED Pediatric

Evaluation of a postoperative neurologic deficit discloses inability to oppose the thumb and little finger, weakness of abduction of the thumb, and loss of flexion of the distal phalanx of the index finger. This problem is most likely related to

(A) paresthesia occurring during an interscalene brachial plexus block
(B) attempted radial artery cannulation at the wrist
(C) inadequate padding under the elbow
(D) attempted venipuncture in the antecubital fossa
(E) abduction of the upper humerus against an "ether screen"

A patient is anesthetized using an inhaled anesthetic with a blood/gas partition coefficient of 13.0. Recovery time depends primarily on

(A) oil/gas solubility of the drug
(B) cardiac output
(C) tidal volume
(D) duration of administration
(E) MAC of the drug

BASIC Pharmacology & Pharmacokinetics

Which of the following statements concerning the ventilatory effects of inhalational anesthesia is true?

(A) Assisted ventilation is not an effective technique to achieve normocarbia
(B) Surgical stimulation does not affect ventilation
(C) Combined doses of nitrous oxide and isoflurane depress ventilation the same as an equipotent dose of isoflurane alone
(D) The ventilatory response to increasing carbon dioxide concentration is normal
(E) The ventilatory response to hypoxemia is preserved

A 72-year-old man has massive venous hemorrhage during a radical prostatectomy. Blood pressure decreases from 110/60 to 75/30 mmHg and central venous pressure decreases from 12 to 4 mmHg. PetC02 decreases from 34 to 24 mmHg during constant minute ventilation. The most appropriate next step should be to

(A) apply positive end-expiratory pressure to the breathing circuit
(B) attempt to aspirate air from the central venous catheter
(C) expand intravascular volume
(D) place the patient in the Trendelenburg position
(E) turn the patient to the left lateral decubitus position
