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. In an emergency situation where a client is unconscious and requires immediate surgery, what action is necessary with regard to informed consent?

• A. The healthcare team will proceed with the surgery as consent is not needed in emergencies.
• B. The healthcare team will wait until the client's family can be contacted for consent.
• C. The healthcare team will contact the hospital clergy to provide informed consent.
• D. The healthcare team will obtain consent from the client's legal guardian before proceeding.

Correct answer: A

Rationale: In emergency situations where obtaining consent is not possible due to the client's condition, healthcare providers are allowed to perform life-saving procedures without informed consent. It is assumed that the client would want to receive necessary treatment to save their life. Therefore, the correct action is for the healthcare team to proceed with the surgery as consent is not needed. Waiting to contact the client's family for consent can delay life-saving treatment, risking the client's life. Contacting the hospital clergy for consent is unnecessary and can cause further delays. Obtaining consent from the client's legal guardian is not feasible in this critical situation and may lead to a delay in providing essential care.

3. A test that can correctly identify those who do not have a given disease is:

• A. specific.
• B. sensitive.
• C. negative culture
• D. marginal finding.

Correct answer: A

Rationale: The correct answer is 'specific.' Specificity refers to the ability of a test to correctly identify individuals who do not have a particular disease. In this case, when the client's lab culture report is negative for the suspected infection, a specific test would correctly identify that the client does not have the disease. 'Sensitive' (Choice B) is incorrect as sensitivity refers to the ability of a test to correctly identify individuals who do have the disease. 'Negative culture' (Choice C) is incorrect as it does not describe the test's ability but rather the result itself. 'Marginal finding' (Choice D) is irrelevant to the concept being tested in this question.

4. When removing a client's gown with an intravenous line, what should the nurse do?

• A. temporarily disconnect the intravenous tubing at a point close to the client and thread it through the gown
• B. cut the gown with scissors
• C. thread the bag and tubing through the gown sleeve, keeping the line intact
• D. temporarily disconnect the tubing from the intravenous container and thread it through the gown

Correct answer: C

Rationale: The correct action when removing a client's gown with an intravenous line is to thread the bag and tubing through the gown sleeve while keeping the line intact. This method ensures that the system remains sterile and reduces the risk of infection. Temporarily disconnecting the tubing at a point close to the client or from the container introduces the potential for contamination. Cutting the gown with scissors should only be done in emergencies as it is not a standard practice and can compromise the integrity of the intravenous line. Therefore, the most appropriate and safe method is to thread the bag and tubing through the gown sleeve.

5. Which action exemplifies the use of evidence-based practice in the delivery of client care?

• A. Advising a client to agree to the treatment recommended by their healthcare provider
• B. Taking a rectal temperature from a client for whom bleeding precautions have been instituted
• C. Donning sterile gloves to change an abdominal wound dressing
• D. Encouraging a client to take an herbal substance to treat their insomnia

Correct answer: C

Rationale: Evidence-based practice is an approach to client care where the nurse integrates the client’s preferences, clinical expertise, and the best research evidence to deliver quality care. Donning sterile gloves to change an abdominal wound dressing exemplifies evidence-based practice as it prevents the entrance of harmful bacteria into the wound, following best practice guidelines. The other options do not align with evidence-based practice. Advising a client to agree to a treatment does not involve integrating research evidence. Taking herbal substances may not be supported by strong research evidence and can pose risks. Additionally, rectal temperature-taking in a client with bleeding precautions can increase the risk of injury to the rectal mucosa, not aligning with best practices in care delivery.
