Nursing Elites

1. What is the term for the tendency of a drug to combine with its receptor?

• A. potency
• B. efficacy
• C. kinetics
• D. affinity

Correct answer: D

Rationale: The correct answer is 'affinity.' Affinity refers to the close relationship or mutual attraction between a drug and its receptor, indicating the strength of the drug-receptor bonding. Potency (Choice A) is related to the dose of a drug needed to produce a specific effect. Efficacy (Choice B) refers to a drug's ability to generate the desired effect. Kinetics (Choice C) deals with forces affecting the motion of material bodies or changes in a system, which is not directly associated with the bonding between a drug and its receptor.

2. In an emergency situation, the nurse determines whether a client has an airway obstruction. Which of the following does the nurse assess?

• A. ability to speak
• B. ability to hear
• C. oxygen saturation
• D. adventitious breath sounds

Correct answer: A

Rationale: In an emergency situation, assessing the client's ability to speak is crucial in determining airway obstruction. If a client can speak, it indicates that the airway is patent and not completely obstructed. Choices B and C, assessing the ability to hear and oxygen saturation, are not directly indicative of an airway obstruction. Choice D, adventitious breath sounds, may be present in conditions like asthma or pneumonia but are not specific to determining an airway obstruction.

3. In an obstetrical emergency, which of the following actions should the nurse perform first after the baby delivers?

• A. Place extra padding under the mother to absorb blood from the delivery.
• B. Cut the umbilical cord using sterile scissors.
• C. Suction the baby's mouth and nose.
• D. Wrap the baby in a clean blanket to preserve warmth.

Correct answer: C

Rationale: In an obstetrical emergency, the immediate priority after the baby delivers is to clear the baby's airway by suctioning the mouth and nose to ensure effective breathing. This action helps prevent potential complications like meconium aspiration. Cutting the umbilical cord, wrapping the baby in a blanket, or placing extra padding under the mother can follow once the baby's airway is clear. Therefore, suctioning the baby's mouth and nose is the most critical and time-sensitive intervention in this scenario. Placing extra padding under the mother is not the immediate priority as ensuring the baby's airway is clear. Cutting the umbilical cord and wrapping the baby in a clean blanket are important but can wait until after ensuring the baby's breathing is not compromised.

4. Delegation of tasks to appropriate personnel allows the nurse to:

• A. ensure tasks are appropriately distributed.
• B. keep other members of the team productive.
• C. maintain tight control of all aspects of the workflow.
• D. recognize the importance of team members' roles.

Correct answer: B

Rationale: Delegating tasks to appropriate personnel is essential for a nurse to keep other team members productive. By assigning tasks that align with the specific roles and responsibilities of team members, the nurse can enhance work effectiveness and efficiency. Option A is incorrect because delegation is not primarily about ensuring tasks are evenly distributed but rather about utilizing team members' skills effectively. Option C is incorrect as maintaining tight control of all aspects of the workflow can hinder teamwork and limit individual growth. Option D is incorrect because effective delegation involves empowering team members to make decisions within their scope of practice, rather than solely recognizing the importance of their roles.

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.
