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. Which behavior by a new nurse would indicate to the charge nurse that this nurse is following standard precautions?
- A. Wearing clean gloves while performing a heel stick on an infant
- B. Wearing the same gloves for assessments of clients in the same room
- C. Wearing sterile gloves when changing the urine bag and nasogastric canister of an infected client
- D. Donning a gown when responding to a request by the family to check the IV pump on a client with rotavirus
Correct answer: A
Rationale: The correct answer is wearing clean gloves while performing a heel stick on an infant. Standard precautions require the use of gloves when there is a risk of exposure to blood or body fluids. Clean gloves are suitable for this task as they provide adequate protection without being sterile. Choice B is incorrect because wearing the same gloves for different clients can lead to cross-contamination, violating standard precautions. Choice C is incorrect as sterile gloves are usually not required for changing a urine bag and nasogastric canister unless a specific aseptic technique is indicated; standard precautions do not demand sterile gloves for such tasks. Choice D is incorrect as donning a gown is not necessary for checking an IV pump unless there is a risk of exposure to bodily fluids that would necessitate full-body protection, which is not indicated in this scenario.
3. In Parkinson's disease, a client's difficulty in performing voluntary movements is known as:
- A. Akinesia.
- B. Dyskinesia.
- C. Chorea.
- D. Dystonia.
Correct answer: C.
Rationale: In Parkinson's disease, the client's difficulty in performing voluntary movements is termed dyskinesia. Dyskinesia refers to the impairment of the ability to execute voluntary muscle movements. Akinesia, on the other hand, refers to the absence or lack of voluntary movement. Chorea is characterized by involuntary, rapid, irregular movements. Dystonia involves sustained muscle contractions resulting in abnormal postures or twisting movements. Therefore, dyskinesia is the specific term used for the described difficulty in Parkinson's disease.
4. When teaching bleeding precautions to a client with leukemia, the PN should include which of the following instructions?
- A. Use a soft toothbrush.
- B. Use dental floss daily.
- C. Hold pressure on any scrapes for 1-2 minutes.
- D. Use a triple-edged razor.
Correct answer: A
Rationale: The correct answer is to 'Use a soft toothbrush.' A soft toothbrush is recommended because it is less likely to cause the gums to bleed in clients with leukemia, who are at risk of bleeding due to overcrowding of white cells at the expense of other cell types like platelets. Choice B, 'Use dental floss daily,' is incorrect because dental floss is contraindicated and can make the gums bleed in clients with leukemia. Choice C, 'Hold pressure on any scrapes for 1-2 minutes,' is incorrect because when clotting is impaired, pressure should be held for 5-10 minutes or longer until the bleeding stops. Choice D, 'Use a triple-edged razor,' is incorrect because an electric razor should be used instead of a triple-edged razor to prevent small cuts and bleeding in clients with leukemia.
5. The LPN is preparing to ambulate a client post total knee replacement. Which of the following actions should the nurse perform prior to ambulating the client?
- A. Assist the client to a sitting position at the edge of the bed
- B. Have the client march in place for 30 seconds
- C. Have the client raise his arms above his head
- D. Ask the client the last time he fell
Correct answer: A
Rationale: The correct action to perform before ambulating a client post total knee replacement is to assist the client to a sitting position at the edge of the bed. This step is crucial to prevent orthostatic hypotension and ensure the client is ready to stand and walk safely. Having the client march in place or raise his arms above his head are not necessary preparations for ambulation. While knowing about the client's fall history is important for safety reasons, it is not the priority action immediately before ambulating the client.
