ATI PN Comprehensive Predictor 2020

Correct Answer: C

Rationale: The correct answer is to hold your breath for 5-10 seconds after inhaling when using a metered-dose inhaler (MDI) for asthma management. This action ensures proper medication absorption in the lungs. Inhaling rapidly (choice A) may cause the medication to impact the mouth/throat rather than the lungs. Exhaling completely before inhalation (choice B) does not optimize medication delivery. Inhaling slowly (choice D) may not allow the medication to reach the lungs effectively.

Correct Answer: D

Rationale: After cataract surgery, it is essential to avoid lying on the affected side to reduce pressure and promote healing. Sleeping on the side of the affected eye (Choice C) may increase pressure on the eye, leading to complications. While using eye drops to soothe dryness (Choice A) is generally recommended postoperatively, it is not as crucial as avoiding pressure on the eye. Rubbing the eye (Choice B) should be avoided to prevent irritation and potential damage, but it is not as critical as avoiding pressure on the affected eye.

Correct Answer: A

Rationale: When assessing a patient with a suspected infection, it is crucial to monitor temperature and check for elevated white blood cells. Elevated temperature indicates a potential infection, and increased white blood cells are a sign of inflammation and the body's response to an infection. Monitoring blood pressure (choice B) and checking for fever (choice B) are not as specific indicators of infection as monitoring temperature and white blood cell count. Assessing changes in mental status and monitoring urine output (choice C) are important aspects of patient assessment but may not directly indicate a suspected infection. Administering antibiotics (choice D) should only be done after a confirmed diagnosis of a bacterial infection, as unnecessary antibiotic use can lead to antibiotic resistance and other adverse effects.

Correct Answer: B

Rationale: The correct answer is to investigate the client's recent medication changes. In a client with dementia who frequently becomes agitated, medication changes can often be a significant factor contributing to their behavior. Checking recent medication changes can help identify if any specific medication is causing or exacerbating the agitation. Choice A about fluid and electrolyte balance is less likely to be the priority unless there are specific indications in the medical record. Choice C, investigating recent changes in cognitive functioning, may be important but addressing the agitation first is a more immediate concern. Choice D, investigating the client's psychosocial environment, is also important but may not directly address the immediate cause of the agitation as medication changes could.

Correct Answer: A

Rationale: The correct answer is A: Hypokalemia. Hypokalemia is an adverse effect of digoxin. Digoxin can cause hypokalemia, which increases the risk of toxicity. Monitoring potassium levels is crucial when a client is taking digoxin. Choices B, C, and D are incorrect as hypernatremia, hypertension, and tachycardia are not directly associated with digoxin use.
