Following are true for Rocuronium Bromide, Except.
Correct Answer
D. Rocuronium has its effect on Conciousness, pain threshold, thinking ability and memory.
Explanation
Rocuronium bromide has its effect on consciousness, pain threshold, thinking ability, and memory. This statement is incorrect because Rocuronium bromide is a neuromuscular blocking agent and its main effect is on skeletal muscle relaxation during surgery or mechanical ventilation. It does not have any direct effect on consciousness, pain threshold, thinking ability, or memory.
2.
Succinylcholine belongs to which of the following groups of Neuromuscular Blocking Agent.
Correct Answer
C. Depolarizing NMBA
Explanation
Succinylcholine is classified as a depolarizing neuromuscular blocking agent. Depolarizing NMBA's work by initially causing depolarization of the motor end plate, which leads to muscle fasciculation. This is followed by a prolonged depolarization phase, during which the muscle remains in a state of paralysis. This medication is commonly used for rapid sequence intubation and short surgical procedures. It is important to note that succinylcholine has a relatively short duration of action compared to non-depolarizing NMBA's, making it a preferred choice in certain clinical situations.
3.
The best explanation for Anesthesia is...
Correct Answer
C. Reversible Loss of Feeling or Sensation in All or Part of Body
Explanation
Anesthesia refers to the reversible loss of feeling or sensation in all or part of the body. This means that the person who undergoes anesthesia will not feel pain or have any sensation in the areas where the anesthesia is administered. It is important to note that anesthesia can be administered either locally, affecting only a specific part of the body, or generally, affecting the entire body. Therefore, the correct answer is "Reversible Loss of Feeling or Sensation in All or Part of Body."
4.
Types of Anesthesia.
Correct Answer
E. All of Above
Explanation
The correct answer is "All of Above" because it includes all the types of anesthesia mentioned in the given options. General anesthesia refers to the complete loss of consciousness during a medical procedure, local anesthesia involves numbing a specific area of the body, regional anesthesia blocks pain in a larger area of the body, and spinal or epidural anesthesia is used for procedures involving the lower part of the body. Therefore, "All of Above" encompasses all the different types of anesthesia listed.
5.
Following are the routes of Anesthesia, Except
Correct Answer
C. Oral Anesthesia
Explanation
The given correct answer is "Oral Anesthesia." This is because oral anesthesia is not a recognized route of administering anesthesia. Anesthesia can be delivered intravenously, through inhalation, or via total intravenous anesthesia, but not orally.
6.
The Triad of Anesthesia include following, Except
Correct Answer
D. Memory Loss
Explanation
The Triad of Anesthesia consists of three components: analgesia (pain relief), sleep/hypnosis (inducing a state of unconsciousness), and muscle relaxation. Memory loss is not a part of the Triad of Anesthesia. This means that memory loss is not one of the essential components required for achieving a state of anesthesia.
7.
According to American Society of Anesthesiologists, ASA-3 assign for the physical status who are;
Correct Answer
D. Patients with severe systemic disease that effect their daily life but not life threatening
Explanation
ASA-3 is assigned to patients with severe systemic disease that affects their daily life but is not life-threatening. This means that these patients have significant medical issues that impact their ability to carry out their daily activities, but their condition is not immediately life-threatening. In the given scenario, a brain dead person being taken for organ donation surgery would fall under this category as they have a severe systemic disease (brain death) that does not pose an immediate threat to their life.
8.
Acetylcholine is one of the most important Neurotransmitters, made up of Acetyl Co-A and Choline Molecules.
Which of the following is it's the site of release, at Neuromuscular junction?
Correct Answer
A. Presynaptic Neuromuscular Vasicles
Explanation
Acetylcholine is released from the presynaptic neuromuscular vesicles at the neuromuscular junction. This is where the nerve terminal and the muscle fiber meet, and acetylcholine is released into the synaptic cleft to bind to the post-synaptic nicotinic receptor sites on the muscle fiber. The inter-synaptic membrane refers to the membrane between two synapses and is not the site of release for acetylcholine. The answer "I don't know" is not correct. Therefore, the correct answer is Presynaptic Neuromuscular Vesicles.
9.
Total clinical Duration...
Correct Answer
A. Time (min) from end of injection till recovery of neuromuscular transmission (twitch height) to a level of 90% of control
Explanation
The correct answer is "Time (min) from end of injection till recovery of neuromuscular transmission (twitch height) to a level of 90% of control." This answer refers to the duration of time it takes for the neuromuscular transmission to recover to 90% of its original strength after the injection has been administered. This is an important measure in clinical settings as it helps determine the effectiveness and duration of the medication or treatment being used.
10.
PACU means
Correct Answer
Post anesthesia care unit
Explanation
PACU stands for Post Anesthesia Care Unit, which is a specialized area in a hospital where patients are closely monitored after undergoing anesthesia. In the PACU, patients are observed for any complications or side effects that may arise from the anesthesia, such as respiratory issues, pain management, and recovery from the effects of anesthesia. The PACU staff ensures that patients are stable and ready to be transferred to a regular hospital room or discharged home.

Select True options from the below statements:
Correct Answer(s)
A. Rocuronium is fully reversable from any depth of block with the use of Sugammadex
D. Sugammadex is modified cyclodextrin and not new to our human body
F. Sugammdex can be a life saver in Cannot Intubate, Cannot Ventilate Situations
Explanation
Rocuronium is fully reversible from any depth of block with the use of Sugammadex. This means that Sugammadex can effectively reverse the effects of Rocuronium, regardless of the level of muscle relaxation.
Sugammadex is a modified cyclodextrin and not new to our human body. This indicates that Sugammadex is a known substance in the human body and has been modified to have specific properties for reversing neuromuscular blockade.
Sugammadex can be a life saver in Cannot Intubate, Cannot Ventilate (CICV) situations. This suggests that Sugammadex can be crucial in emergency situations where a patient cannot be intubated or ventilated, providing a potential life-saving solution.

The Use of Rocuronium in Hepatic and Renal Insufficiency:
Correct Answer(s)
A. The standard intubation dose for geriatric patients and patients with hepatic
and/or biliary tract disease and/or renal failure during routine anesthesia is 0.6
mg.kg-1 rocuronium bromide
B. A dose of 0.6 mg.kg-1 should be considered for
rapid sequence induction of anesthesia in patients in which a prolonged
duration of action is expected
C. Regardless of the anesthetic technique used,
the recommended maintenance dose for these patients is 0.075-0.1 mg.kg-1 rocuronium bromide, and the recommended infusion rate is 0.3-0.4 mg.kg-1.h-1
Explanation
The recommended dose of Rocuronium for geriatric patients and patients with hepatic and/or biliary tract disease and/or renal failure during routine anesthesia is 0.6 mg.kg-1. This dose should also be considered for rapid sequence induction of anesthesia in patients where a prolonged duration of action is expected. Regardless of the anesthetic technique used, the recommended maintenance dose for these patients is 0.075-0.1 mg.kg-1, and the recommended infusion rate is 0.3-0.4 mg.kg-1.h-1. This is because the dose of Rocuronium should be the same as that for a normal healthy adult, as it does not affect liver enzymes and renal function.

rapid sequence induction technique, provided no intubation difficulties are
anticipated and a sufficient dose of anesthetic agent is administered
C. Esmeron, administered in
doses of 0.6 mg.kg-1, has been shown to be safe in parturients undergoing
Cesarean section
D. Esmeron does not affect Apgar score, fetal muscle tone
nor cardiorespiratory adaptation.
E. Only a dose of 0.6 mg.kg-1 is recommended in this patient group.
F. Rocuronium should be given to lactating women only when the
attending pHysician decides that the benefits outweigh the risks.
Explanation
Rocuronium bromide is a medication used for muscle relaxation during surgery. The given answer states that there is no clinical data available on the use of rocuronium in pregnant women, so caution should be exercised when prescribing it to them. However, it can be used during a Cesarean section if there are no anticipated difficulties with intubation and an adequate dose of anesthetic agent is given. Studies have shown that a dose of 0.6 mg.kg-1 of Esmeron (rocuronium) is safe for parturients undergoing a Cesarean section and does not affect the Apgar score, fetal muscle tone, or cardiorespiratory adaptation. Lactating women should only receive rocuronium if the attending physician determines that the benefits outweigh the risks.

This suggests that there may be potential risks or complications associated with using rocuronium bromide in this specific situation, and it is advisable to explore other options.
22.
For Maintenance dose of Rocuronium,
The recommended maintenance dose is 0.15 mg.kg-1 rocuronium bromide; in the case of long-term inhalational anesthesia, this should be reduced to 0.075-0.1 mg.kg-1 rocuronium bromide. The maintenance doses should best be given when twitch height has recovered to 25% of control twitch height, or when 2 to 3 responses to a train of four stimulation are present.
Correct Answer
A. True
Explanation
The explanation for the given correct answer is that the recommended maintenance dose of Rocuronium is indeed 0.15 mg.kg-1 rocuronium bromide. However, in the case of long-term inhalational anesthesia, the dose should be reduced to 0.075-0.1 mg.kg-1 rocuronium bromide. It is also recommended to administer the maintenance doses when the twitch height has recovered to 25% of control twitch height or when 2 to 3 responses to a train of four stimulation are present. Therefore, the statement "The recommended maintenance dose is 0.15 mg.kg-1 rocuronium bromide" is true.
23.
For Continuous Infusion of Rocuronium,
If rocuronium bromide is administered by continuous infusion, it is recommended to give a loading dose of 0.6 mg.kg-1 rocuronium bromide and, when neuromuscular block starts to recover, to start administration by
infusion. The infusion rate should be adjusted to maintain twitch response at 10% of control twitch height or to maintain 1 to 2 responses to train of four stimulation. In adults under intravenous anesthesia, the infusion rate required to maintain neuromuscular block at this level ranges from 0.3-0.6 mg.kg-1.h-1, and under inhalational anesthesia the infusion rate ranges from 0.3-0.4 mg.kg-1.h-1. Continuous monitoring of neuromuscular block is recommended since infusion rate requirements vary from patient to patient and with the anesthetic method used.
Correct Answer
A. True
Explanation
The statement is true because when administering rocuronium bromide by continuous infusion, it is recommended to give a loading dose and then start administration by infusion. The infusion rate should be adjusted to maintain the desired level of neuromuscular block. The recommended infusion rates vary depending on the type of anesthesia used. Continuous monitoring of neuromuscular block is also recommended as the infusion rate requirements can vary between patients and with different anesthetic methods.
24.
For Obese Patients,
When used in overweight or obese patients (defined as patients with a body weight of 30% or more above ideal body weight) doses should be reduced taking into account ideal body weight.
Correct Answer
A. True
Explanation
The explanation for the answer "True" is that in obese patients, doses of medication should be reduced based on their ideal body weight rather than their actual body weight. This is because the ideal body weight is a more accurate representation of the patient's size and metabolism, and using it to calculate the dosage can help prevent potential complications or adverse effects.
