Correct Answer: B

Rationale: The correct answer is B: 'Keep oxygen tanks upright at all times.' Oxygen tanks should be stored in an upright position to prevent leaks and accidents. Choice A is incorrect as smoking should never be allowed near oxygen due to the risk of fire. Choice C is incorrect as oxygen equipment should be stored in a well-ventilated area, not in a closet. Choice D is incorrect as oxygen tanks must be kept a minimum of 5 to 10 feet away from heat sources to prevent combustion. Therefore, the best practice is to keep oxygen tanks upright to ensure safety.

Correct Answer: B

Rationale: Acetylcysteine is the antidote for acetaminophen overdose. It works by replenishing glutathione, a key component in detoxifying acetaminophen metabolites, thus preventing liver damage. Naloxone is used to reverse opioid overdose, not acetaminophen. Flumazenil is a benzodiazepine antidote. Activated charcoal is used to limit absorption in cases of poisoning, but it is not the antidote for acetaminophen overdose.

Correct Answer: A

Rationale: Correct answer: Monitoring for signs of infection and ensuring airway patency is crucial in managing a patient with a tracheostomy. This involves observing for redness, swelling, or discharge at the stoma site, as well as assessing for any signs of respiratory distress. Choice B, suctioning airway secretions and providing humidified air, is important for maintaining airway hygiene but may not be the initial assessment priority. Choice C, inspecting the stoma site and cleaning with saline, is part of routine tracheostomy care but does not address immediate assessment and management needs. Choice D, providing education on tracheostomy care, is valuable but not the primary action required in the assessment and management of a patient with a tracheostomy.

Correct Answer: C

Rationale: In this situation, the nurse's priority is to determine if the client is experiencing psychotic thinking as it addresses the immediate safety concern. Psychotic thinking may pose a risk to the client's safety or the safety of others. Referring the client to a mental health counselor (choice A) may be appropriate but not the priority when safety is a concern. Encouraging the client to express their feelings (choice B) and asking about their social support system (choice D) are essential aspects of care but are secondary to addressing immediate safety issues.

Correct Answer: A

Rationale: Administering oxygen and calling for emergency assistance are the immediate priorities when managing a suspected pulmonary embolism. Oxygen helps support the patient's respiratory function, while emergency assistance is crucial for further evaluation and treatment. Positioning the patient in a prone position or giving fluids can worsen the condition by impeding blood flow. Administering anticoagulants may be part of the treatment plan but is not the initial response. Thrombolytics and chest physiotherapy are not first-line treatments for suspected pulmonary embolism and can even be harmful without prior evaluation.
