Question 1 of 5
A client asks a nurse working in a dental office what type of drug the dentist uses to provide anesthesia during the extraction of the client's wisdom teeth. The dentist uses an anesthetic gas, also known as laughing gas. This agent is:
Correct Answer: A
Rationale: The correct answer is nitrous oxide. Nitrous oxide is commonly known as laughing gas and is used as an anesthetic gas for procedures like dental extractions. It produces analgesia and mild euphoria without loss of consciousness. Nitrogen is a nonmetallic element found in air, while nitric oxide is a vasodilator produced from L-arginine. Nitrogen dioxide is a poisonous gas found in smog and exhaust fumes and is not used for anesthesia.
Question 2 of 5
A newborn baby exhibits a reflex that includes hand opening, abducted, and extended extremities following a jarring motion. Which of the following correctly identifies the reflex?
Correct Answer: D
Rationale: The Moro reflex, also known as the startle reflex, is the correct answer. This reflex is characterized by the baby's response to a sudden head movement or loud noise, causing them to open their hands, extend their arms, and then bring them back towards their body. The characteristics mentioned in the question - hand opening, abducted, and extended extremities following a jarring motion - align with the Moro reflex. The asymmetrical tonic neck reflex (ATNR) involves the head turning to one side with extension of the same side's arm and leg, not the described characteristics. The grasping reflex involves the baby's response to touch on the palm, causing them to grasp an object. While the Moro reflex is often referred to as the startle reflex due to its response to sudden stimuli, the specific characteristics described in the question match the Moro reflex.
Question 3 of 5
A nurse is assessing an 18-year-old female who has recently suffered a TBI. The nurse notes a slower pulse and impaired respiration. The nurse should report these findings immediately to the physician due to the possibility the patient is experiencing which of the following conditions?
Correct Answer: A
Rationale: The nurse should report the slower pulse and impaired respiration to the physician immediately as they are indicative of increased intracranial pressure (ICP) following a traumatic brain injury (TBI). These signs suggest that there may be a rise in pressure within the skull, which can be a life-threatening condition requiring urgent intervention. Options B and C are unlikely in this scenario as they do not correlate with the symptoms presented. Meningitis (Option
D) typically presents with different signs and symptoms, such as fever, headache, and neck stiffness, which are not described in the patient's case.
Question 4 of 5
A nurse is returning phone calls in a pediatric clinic. Which of the following reports most requires the nurse's immediate attention and phone call?
Correct Answer: A
Rationale: The correct answer is the 8-year-old boy with vomiting, slower movements, and a history of an atrioventricular shunt placement. This report requires immediate attention because the symptoms could indicate a blocked shunt, which is a serious medical condition needing urgent evaluation and intervention. Slower movements in the context of an atrioventricular shunt history could suggest increased intracranial pressure. The other choices involve less urgent issues: choice B describes post-exercise pain, choice C presents with a low-grade fever and headache that could be due to a mild infection, and choice D reports itching associated with a cast, which is a common issue and less critical compared to a potentially blocked shunt.
