Nursing Elites

1. The nurse is teaching a client about sleep and gives background information on normal sleep patterns. Which of the following substances promotes sleep?

• A. serotonin
• B. cortisol
• C. alcohol
• D. narcotics

Correct answer: A

Rationale: Serotonin is a substance found in the body that promotes sleep. It plays a role in the synthesis of a hypnogenic factor that directly induces sleep. Cortisol is a stress hormone that can disrupt sleep patterns. Alcohol can disrupt REM sleep and negatively impact sleep quality. Narcotics, like alcohol, can interfere with sleep architecture and lead to poor quality sleep. Therefore, the correct answer is serotonin as it is associated with promoting sleep, while the other substances listed can have negative effects on sleep patterns.

2. Which of the following lab values is elevated first after a client has a myocardial infarction?

• A. LDH
• B. troponin
• C. CPK
• D. SGOT

Correct answer: B

Rationale: The correct answer is troponin. Troponin levels are the most specific and sensitive markers for myocardial infarction, and they begin to rise within a few hours after the event. CPK, SGOT, and LDH are also enzymes that can indicate myocardial damage, but troponin is the earliest and most specific indicator. CPK typically rises 4-8 hours after an infarction, followed by SGOT (AST) at 8-12 hours, and LDH at 12-24 hours post-infarction.

3. The nurse is preparing to administer the 9 am dose of IV antibiotics when she notes the IVAC cord is frayed with wiring visible. What action should be her priority for this client?

• A. Notify maintenance to come and check the pump immediately.
• B. Continue with the administration of the antibiotic and fill out an equipment maintenance request.
• C. Immediately discontinue the use of this IVAC pump and obtain a replacement.
• D. Tag the equipment for maintenance.

Correct answer: C

Rationale: The correct action is to immediately discontinue the use of the IVAC pump and obtain a replacement because the frayed cord poses a safety risk to the client. Continuing to use the pump with visible wiring could lead to electric shock or other serious harm to the client. Notifying maintenance to come and check the pump immediately (Choice A) may cause unnecessary delays in ensuring the client's safety. Continuing with the administration of the antibiotic and filling out an equipment maintenance request (Choice B) is unsafe as it ignores the immediate danger. Tagging the equipment for maintenance (Choice D) does not address the urgent need to protect the client from harm.

4. A nursing student is assigned to care for a client who requires a total bed bath. When the student explains to the client that she is going to gather supplies to administer the bath, the client states, 'I don't want a bath. I've been up all night, and I'm clean enough.' The student reports the client's refusal to the nurse. Which action by the nurse is appropriate?

• A. Telling the nursing student to persuade the client to have a bath so that the evening shift staff will not have to do it
• B. Telling the nursing student to allow the client to rest
• C. Telling the client that the refusal of care will be informed to the health care provider
• D. Telling the nursing student to give the client the bath anyway

Correct answer: B

Rationale: The client has the right to refuse a treatment or procedure, and if the client does refuse, the nurse must respect the client's decision. Therefore, the nurse would allow the client to rest. Persuading the client to have a bath and giving the bath anyway are both inappropriate as they violate the client's rights. Informing the health care provider of the refusal of care can be discussed with the client if needed, but the immediate action should be to respect the client's wishes and allow them to rest.

5. Which medication might the healthcare provider prescribe if the client expresses discomfort with being in the enclosed space of a CT scanner?

• A. Valium (diazepam)
• B. Clozaril (clozapine)
• C. Catapres (clonidine)
• D. Lasix (furosemide)

Correct answer: A

Rationale: Valium (diazepam) is a sedative that might be prescribed to help a client who feels uncomfortable in the confined space of a CT scanner. Diazepam can help reduce anxiety and promote relaxation, making the scanning process more tolerable. Clozaril (clozapine), Catapres (clonidine), and Lasix (furosemide) are not sedatives and wouldn't be appropriate for alleviating discomfort related to being in an enclosed space. Clozaril is an antipsychotic used to treat schizophrenia, Catapres is a blood pressure medication, and Lasix is a diuretic used to treat fluid retention, so they are not indicated for this situation.
