Nursing Elites

1. Which neurotransmitter is most closely associated with mood regulation and is targeted by antidepressants?

• A. Serotonin
• B. Dopamine
• C. GABA
• D. Acetylcholine

Correct answer: A

Rationale: The correct answer is A: Serotonin. Serotonin plays a vital role in mood regulation, and its imbalance is often associated with depression. Many antidepressants function by boosting serotonin levels in the brain. Dopamine (Choice B) is more linked to reward and pleasure pathways in the brain, not primarily targeted for mood regulation. GABA (Choice C) is an inhibitory neurotransmitter that helps reduce neuronal excitability, not primarily associated with mood regulation. Acetylcholine (Choice D) is involved in muscle movement and cognitive functions, not the primary target of antidepressants for mood regulation.

2. At what age does a 9-year-old child typically lose which of the following teeth?

• A. Central incisor
• B. Second molar
• C. Lateral incisor
• D. Cuspid

Correct answer: A

Rationale: A 9-year-old child typically loses their central incisors, not the lateral incisors or second molars. The central incisors are usually among the first teeth that children lose around 6 to 7 years of age, as part of the natural process of shedding primary teeth to make way for permanent teeth. The second molars and cuspids are typically lost later in the mixed dentition phase. Therefore, option A, 'Central incisor,' is the correct answer.

3. A nurse is assessing a day-old infant for jaundice. Which of the following is the best method for this?

• A. Applying pressure over a bony area such as the forehead and evaluating the skin color after the pressure is removed
• B. Assessing the color of the infant’s hands and feet
• C. Assessing the infant’s tongue
• D. Assessing the infant’s arms and legs

Correct answer: A

Rationale: The correct answer is A. Applying pressure over a bony area and evaluating the skin color after the pressure is removed is the most accurate method for assessing jaundice in a day-old infant. This technique helps in identifying any yellowing of the skin, which is a key indicator of jaundice. Choices B, C, and D are less effective methods for assessing jaundice in a newborn. Assessing the color of the hands and feet may not give a reliable indication of jaundice, while evaluating the tongue, arms, and legs are not as specific or accurate as applying pressure over a bony area.

4. The nurse and UAP enter a client's room and find the client lying on the bed. The nurse determines that the client is unresponsive. Which instruction should the nurse give the UAP first?

• A. Obtain emergency help
• B. Feel for a carotid pulse
• C. Bring a glucometer to the room
• D. Check the blood pressure

Correct answer: A

Rationale: The correct answer is to instruct the UAP to obtain emergency help first. In a situation where a client is unresponsive, the priority is to ensure that help is summoned promptly. This allows for the availability of necessary resources and assistance for resuscitation or other emergency interventions. Feeling for a carotid pulse or checking the blood pressure can be important assessments but are secondary to obtaining immediate help. Bringing a glucometer to the room, while relevant in certain situations, is not the priority when the client's unresponsiveness indicates a need for urgent intervention.

5. While ambulating in the hallway following an appendectomy yesterday, a client complains of chest tightness and shortness of breath. Which action should the nurse implement first?

• A. Administer sublingual nitroglycerin
• B. Assist the client back to the room
• C. Have the client sit down in the hall
• D. Obtain a 12-lead electrocardiogram

Correct answer: C

Rationale: Having the client sit down in the hallway is the first action the nurse should implement. This is crucial to prevent further strain on the heart and to provide a safer environment for assessment and potential emergency intervention. Administering sublingual nitroglycerin (Choice A) may be appropriate later but should not precede ensuring the client's immediate safety. Assisting the client back to the room (Choice B) may not be advisable if the client is experiencing chest tightness and shortness of breath. Obtaining a 12-lead electrocardiogram (Choice D) is important but would not be the initial action to address the client's immediate symptoms.
