PN ATI Capstone Adult Medical-Surgical 1 Quiz

Correct Answer: B

Rationale: When using the ABC approach to client care, the nurse should identify that the priority intervention is administering oxygen. In this scenario, the client's oxygen saturation is only 91%, which is below the normal range of 95% and above. Oxygen is essential for adequate tissue perfusion and oxygenation of vital organs. Administering oxygen takes precedence over other interventions to ensure the client's physiological needs are met first. Choice A can be addressed after ensuring adequate oxygenation. Choice C is important for preventing postoperative complications but is not as urgent as addressing oxygen saturation. Choice D is a common postoperative intervention, but in this case, ensuring adequate oxygenation is the priority over IV fluid administration.

Correct Answer: A

Rationale: A sodium level of 122 mEq/L indicates hyponatremia, which is characterized by decreased deep tendon reflexes. Hyponatremia leads to neurological symptoms such as altered reflexes. Choices B, C, and D are not typically associated with hyponatremia. Positive Trousseau's sign is related to hypocalcemia, hypoactive bowel sounds can be seen in paralytic ileus or decreased peristalsis, and sticky mucous membranes are not specific findings related to sodium imbalances.

Correct Answer: B

Rationale: Tuberculosis is spread through small droplets, measuring less than 5 microns, which can remain airborne for extended periods. The nurse should place a client with TB under airborne precautions to prevent the transmission of the disease. Choice A, contact precautions, are used for diseases that spread by direct or indirect contact. Choice C, droplet precautions, are for diseases transmitted by large droplets. Choice D, protective environment, is used for clients who have compromised immune systems.

Correct Answer: A

Rationale: In the scenario of a client experiencing prolonged seizures, such as status epilepticus, the priority is to administer a benzodiazepine to stop the seizure activity. Diazepam is the medication of choice for this situation due to its rapid onset of action and effectiveness in terminating seizures quickly. Lorazepam, although another benzodiazepine, is typically given through routes other than oral (PO) administration in emergency situations. Diltiazem is a calcium channel blocker used for cardiac conditions, not for seizure management. Clonazepam is a benzodiazepine, but it is usually not the first choice in the acute management of status epilepticus.

Correct Answer: A

Rationale: The correct answer is A, Propofol. Propofol is a short-acting anesthetic medication commonly used to induce moderate sedation for procedures like a colonoscopy. This medication provides rapid onset and recovery, making it an ideal choice for such procedures. Choice B, Pancuronium, is a neuromuscular blocking agent used for muscle relaxation during surgery and would not be appropriate for sedation during a colonoscopy. Choice C, Promethazine, is an antihistamine used for nausea and motion sickness, not for anesthesia. Choice D, Pentoxifylline, is a medication used to improve blood flow in patients with circulation problems and is not indicated for anesthesia during a colonoscopy.
