What is the most important intervention for a client with delirium?

Correct Answer: B

Rationale: The correct answer is to identify any reversible causes of delirium. Delirium can be caused by various factors such as infections, medications, or metabolic imbalances. Addressing these underlying causes can help resolve delirium. Administering sedative medication (Choice A) can worsen delirium by further altering mental status. Providing a low-stimulation environment (Choice C) is helpful to manage delirium symptoms, but it is not the most important intervention. Increasing environmental stimulation (Choice D) is contraindicated in delirium as it can exacerbate confusion and agitation.

Correct Answer: A

Rationale: The correct answer is A. Systolic heart failure is characterized by reduced ejection fraction, meaning the heart is not pumping effectively. Diastolic heart failure, on the other hand, is characterized by preserved ejection fraction, indicating that the heart has difficulty relaxing and filling properly. Choices B, C, and D are incorrect because they do not accurately describe the key differences between systolic and diastolic heart failure.

Correct Answer: B

Rationale: Constant bubbling in the water seal chamber indicates an air leak, which should be reported to the provider. This finding suggests that the chest tube system is not functioning properly, leading to potential complications such as pneumothorax. Drainage of 75 mL in the first hour after surgery is within the expected range for a chest tube. Tidaling in the water seal chamber is a normal fluctuation and indicates proper functioning of the system. Client report of pain at the chest tube insertion site is expected after surgery and can be managed with appropriate pain management measures.

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: B

Rationale: The correct answer is B - 'Identify the underlying causative condition.' When a client is experiencing delirium, it is crucial to determine the root cause of this acute change in mental status. This can involve a thorough assessment to identify any medical conditions, medications, infections, or environmental factors that may be contributing to the delirium. By pinpointing the underlying cause, appropriate interventions can be implemented to address the specific issue. Choices A, C, and D are incorrect because controlling behavioral symptoms with low-dose psychotropics, increasing environmental stimulation, and administering antipsychotic medication do not target the primary need of identifying and addressing the causative condition of delirium.

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: A

Rationale: The correct answer is to administer insulin. In hyperglycemia, there is an excess of glucose in the blood, which needs to be lowered. Insulin is the primary medication used to lower blood glucose levels by facilitating the uptake of glucose into cells. Encouraging the client to exercise may further increase blood glucose levels due to the release of stress hormones, so it is not the priority. While staying hydrated is important, it will not directly address the high blood glucose levels seen in hyperglycemia. Glucagon is used to treat severe hypoglycemia, not hyperglycemia, so it is not the priority in this situation.

Correct Answer: B

Rationale: The correct initial action when a client with a tracheostomy exhibits respiratory distress is to suction the tracheostomy. This helps to clear secretions and improve the client's ability to breathe. Notifying the provider (choice A) can cause a delay in immediate intervention. Administering a bronchodilator (choice C) may be necessary but is not the priority in this situation. Increasing the oxygen flow rate (choice D) can be helpful but should come after addressing the immediate need for suctioning to clear the airway.

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.
