2.Inhalation sedation involves patients breathing gases. The gases used are Oxygen and Nitrous Oxide. What is the lowest level of Oxygen that can be administered to the patient?
30%
3.Gaining valid consent is an essential part of all treatment under conscious sedation. According to the UK, at what age are you presumed to have the capacity to consent unless there is evidence to the contrary? (
16
4.An inhalation sedation machine is required to have number of features to ensure patient safety. Which of the following features would allow the patient to breathe atmospheric air if the flowrate were set too low?
Entrainment valve
A student dental nurse that you work with has heard that intranasal sedation can be a useful method for administering sedative drugs for patients with special needs. They ask which drug would be given by this route. What is the correct response to this question when following current UK guidelines?
Midazolam
Inhalation sedation is a common technique used to help treat children in the UK. You are caring for a patient and notice that the flow rate of the machine is currently 6 l/min. Which of the measurable lung volumes does this most closely relate to?
Tidal volume
Some medications are classified as controlled drugs under the misuse of drugs legislation. Many of the drugs which may be used in conscious sedation fall under this control. Which of the drugs in the list below is not categorised as a controlled drug
Flumazenil
In some situations, you may be required to take a pulse manually. Which artery is palpated when required to a take a pulse on the inside of the patient thigh?
Femoral
9.There are specific sedation guidelines relating to gaining consent from patient. General GDC guidance for obtaining consent is contained within the ‘Standards for the Dental Team’ document. Which principle relates to this topic?
3
A pulse oximeter is required when sedating patient with benzodiazepines. Which of the following complications is the device principally designed to detect?
Respiratory depression
Before treatment is provided under conscious sedation, the dental sedation nurse should confirm that pre-operative instructions have been followed. If a patient has not removed their nail varnish, which of the following observations is most likely to be inaccurate
Oxygen saturation
The body mass index may have been used to indicate if a patient is suitable for conscious sedation within a general dental surgery. How is the BMI calculated?
Mass (kg) ÷ Height (m)²
Knowledge of pharmacology allows us to understand the properties of the drugs we use. Which common property of sedative drugs tells us that it reduces the sensation of nausea?
Anti-emetic
Despite the need for electro-mechanical observations, it is vital that the dental sedation nurse can use their visual clinical observations to make sensible judgements about the patient’s status. If a patient was exhibiting the sign of ‘cyanosis’, which of the following changes is most likely to have occurred
Decreased respiration rate
The alveoli allow gaseous exchange between the lungs and the blood stream. The proportion of which the following gases constitutes approximately 16% of exhaled air?
Oxygen
The drugs used in dentistry have multiple effects on our patients. Which of the following effects of a drug means that it reduces the feeling of fear?
Anxiolytic
During the recovery of a patient who has had Intravenous Sedation, the dental nurse should undertake several observations to ensure the patient is fully recovered. Which of the following should the dental nurse ensure takes place during recovery?
Clinically monitor the patient throughout
The respiration rate of a resting adult is?
12-20 breaths per minute
Drugs administered via the sublingual, buccal, intranasal, and rectal routes are all absorbed across a mucosal surface. What is this absorption route?
Transmucosal
Our vital organs all have important roles in keeping us healthy. Some of them help us to manage drugs given during conscious sedation. Which of the following vital organs is the primary organ concerned with excretion
Kidneys
The drug midazolam works by increasing the effectiveness of a neurotransmitter within the central nervous system. Which inhibitory neurotransmitter is associated with sedation when using midazolam?
Gamma Aminobutyric Acid
When assessing a patient during a medical emergency the DRABC approach should be used, at which stage of this assessment would a blood glucose measurement be taken
Disability
Exposure to any drug comes with the risk of encountering undesirable side effects. Long term exposure to Nitrous Oxide can lead to a deficiency of vitamin B12. Which of the bodies systems would be affected by this deficiency?
Haematological
There are a number of complications, which can occur following cannulation. Which of the possible complications listed below is inflammation within a vein relating to a clot, which occurs a number of days after cannulation?
Thrombophlebiits
Blood pressure is an observation that can tell us about a patient’s general health and their current state; however, this relies on having knowledge of normal values. What is the normal value for the diastolic blood pressure of a healthy adult?
80 mmHg
