1. 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:
- A. nitrous oxide.
- B. nitrogen.
- C. nitric oxide.
- D. nitrogen dioxide.
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.
2. What vitamin is important in preventing peripheral neuritis in a client with alcohol abuse?
- A. Vitamin D
- B. Fat-soluble vitamins
- C. B vitamins
- D. Potassium
Correct answer: B
Rationale: The correct answer is 'Fat-soluble vitamins.' Vitamin B, not Vitamin D, is crucial in preventing peripheral neuritis in individuals with alcohol abuse. Vitamin B deficiency, particularly B1 (thiamine), is commonly associated with peripheral neuritis in alcoholics. Therefore, choices A, C, and D are incorrect. Vitamin D is not directly related to peripheral neuritis, and potassium deficiency typically presents with different symptoms.
3. The nurse is caring for a burn victim with a skin graft to the hand. The area is pale and mottled but has good capillary refill. What is the nurse's best action at this time?
- A. Warm the room
- B. Submerge the hand in warm water
- C. Order a K pad and apply to hand
- D. Have the client exercise the fingers to increase blood flow
Correct answer: A
Rationale: The correct action for the nurse to take when caring for a burn victim with a skin graft to the hand, exhibiting pale and mottled skin but good capillary refill, is to warm the room. By warming the room, the nurse helps promote circulation and maintain a conducive environment for healing. Submerging the hand in warm water can pose a risk of injury or infection to the graft site. Ordering a K pad and applying it to the hand may not be necessary at this time and could potentially cause harm. Having the client exercise the fingers to increase blood flow is also not recommended as it may interfere with the healing process of the skin graft.
4. A patient has recently been prescribed Norvasc. Which of the following side effects should the patient specifically watch out for?
- A. Hypotension and Angina
- B. Hypertension
- C. Lower extremity edema
- D. Peripheral sensory loss and SOB
Correct answer: A
Rationale: The correct answer is 'Hypotension and Angina.' Norvasc is a medication known to cause hypotension (low blood pressure) and angina (chest pain) as side effects. These side effects are important for the patient to watch out for as they can indicate potential issues related to the medication. Choice B ('Hypertension') is incorrect as Norvasc is actually used to treat hypertension, not cause it. Choice C ('Lower extremity edema') is not a common side effect of Norvasc. Choice D ('Peripheral sensory loss and SOB') is not typically associated with Norvasc's side effects.
5. Which microorganism is most commonly associated with gastritis?
- A. Syphilis
- B. Cytomegalovirus
- C. H. pylori
- D. Mycobacterium
Correct answer: C
Rationale: H. pylori is the most common microorganism associated with gastritis, present in over 80% of cases. While syphilis, cytomegalovirus, and mycobacterium can also cause gastritis, they are much less prevalent compared to H. pylori. Therefore, the correct answer is H. pylori.
