PN Exit Exam 2023 Quizlet
1. When caring for a patient with a fresh tracheostomy, what is the nurse’s first priority?
- A. Providing humidified oxygen
- B. Ensuring the tracheostomy ties are secure
- C. Suctioning the tracheostomy tube as needed
- D. Monitoring for signs of infection
Correct answer: B
Rationale: The correct answer is B: Ensuring the tracheostomy ties are secure. This is the nurse's first priority because it is critical to prevent accidental decannulation, which could compromise the patient’s airway. Providing humidified oxygen, suctioning the tracheostomy tube, and monitoring for signs of infection are important aspects of care but ensuring the tracheostomy ties' security takes precedence to maintain the patient's airway.
2. A full-term, 24-hour-old infant in the nursery regurgitates and suddenly turns cyanotic. Which immediate intervention should the PN implement?
- A. Stimulate the infant to cry
- B. Give oxygen by positive pressure
- C. Suction the oral and nasal passages
- D. Turn the infant onto the right side
Correct answer: C
Rationale: Suctioning the oral and nasal passages is the correct immediate intervention in this scenario. Regurgitation leading to cyanosis indicates a potential airway obstruction, which requires prompt action to clear. Stimulating the infant to cry (Choice A) may not address the underlying issue of airway obstruction. Giving oxygen by positive pressure (Choice B) can be beneficial, but clearing the airway obstruction takes precedence. Turning the infant onto the right side (Choice D) does not directly address the need to clear the airway.
3. Which type of isolation precaution is required for a patient with tuberculosis (TB)?
- A. Droplet precautions
- B. Contact precautions
- C. Airborne precautions
- D. Standard precautions
Correct answer: C
Rationale: The correct answer is C: Airborne precautions. Tuberculosis (TB) is transmitted via airborne particles, thus requiring airborne precautions to prevent the spread of infection. This includes using an N95 respirator to filter out small infectious particles. Droplet precautions (Choice A) are used for diseases that spread through large respiratory droplets. Contact precautions (Choice B) are for direct or indirect contact with the patient or their environment. Standard precautions (Choice D) are used for all patients to prevent the spread of infection through blood, bodily fluids, non-intact skin, and mucous membranes.
4. A male client attends a community support program for mentally impaired and chemically abusing clients. The client tells the PN that his drugs of choice are cocaine and heroin. What is the greatest health risk for this client?
- A. Hypertension
- B. Hepatitis
- C. Glaucoma
- D. Diabetes
Correct answer: B
Rationale: The correct answer is B: Hepatitis. Hepatitis is the greatest health risk for this client due to the potential for contracting the disease through needle-sharing, common among drug users. This can lead to serious liver complications. While hypertension, glaucoma, and diabetes are all important health concerns, they are not directly associated with the drug abuse mentioned in the scenario.
5. 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.
