which client is at the greatest risk for developing delirium

HESI LPN

CAT Exam Practice Test

1. Which client is at the greatest risk for developing delirium?

A. An adult client who cannot sleep due to constant pain
B. An older client who attempted suicide 1 month ago
C. A young adult who takes antipsychotic medications twice a day
D. A middle-aged woman who uses a tank for supplemental oxygen

Correct answer: B

Rationale: The correct answer is B because older adults are at higher risk for delirium, especially following a recent suicide attempt, which can be a significant stressor. Choice A is less likely to develop delirium solely due to difficulty sleeping; delirium is more complex and multifactorial. Choice C, a young adult taking antipsychotic medications, may be at risk for other conditions but not necessarily delirium. Choice D, a middle-aged woman using supplemental oxygen, is not directly linked to an increased risk of delirium compared to the older client who recently attempted suicide.

2. An older male resident of a long-term care facility has been scratching his legs for the past 2 days. Which intervention should the nurse implement?

A. Explain the importance of bathing or showering daily
B. Encourage fluid intake of at least 2,000 ml daily
C. Keep the legs covered as much as possible
D. Apply emollient to the affected area at least twice daily

Correct answer: D

Rationale: The correct intervention for the nurse to implement in this scenario is to apply emollient to the affected area at least twice daily. This is because applying emollients helps address dry skin, which is a common cause of itching in older adults. Explaining the importance of bathing or showering daily (Choice A) may be helpful for general hygiene but may not specifically address the itching. Encouraging fluid intake (Choice B) and keeping the legs covered (Choice C) are not directly related to addressing the itching caused by dry skin.

3. The parents of a 6-year-old recently diagnosed with asthma should be taught that the symptom of acute episodes of asthma is due to which physiological response?

A. Inflammation of the mucous membrane & bronchospasm
B. Increased mucus production and bronchoconstriction
C. Allergic reactions and hyperventilation
D. Airway narrowing and decreased lung capacity

Correct answer: A

Rationale: The correct answer is A: Inflammation of the mucous membrane & bronchospasm. Acute asthma episodes are primarily caused by inflammation of the airways and bronchospasm, which lead to airway obstruction. Increased mucus production and bronchoconstriction (Choice B) are part of the physiological responses in asthma but do not directly cause acute episodes. Allergic reactions and hyperventilation (Choice C) are related to asthma triggers and responses but are not the direct causes of acute episodes. Airway narrowing and decreased lung capacity (Choice D) are consequences of inflammation and bronchospasm but do not explain the physiological response leading to acute asthma episodes.

4. An adult client with a broken femur is transferred to the medical-surgical unit to await surgical internal fixation after the application of an external traction device to stabilize the leg. An hour after an opioid analgesic was administered, the client reports muscle spasms and pain at the fracture site. While waiting for the client to be transported to surgery, which action should the nurse implement?

A. Observe for signs of deep vein thrombosis.
B. Administer a PRN dose of a muscle relaxant.
C. Check the client’s most recent electrolyte values.
D. Reduce the weight on the traction device.

Correct answer: B

Rationale: The correct answer is B: Administer a PRN dose of a muscle relaxant. Muscle spasms and pain might be relieved by muscle relaxants, which are appropriate before surgery. Choice A is incorrect because the client is experiencing muscle spasms, not signs of deep vein thrombosis. Choice C is not the most immediate action needed in this situation. Choice D is incorrect because reducing the weight on the traction device would not directly address the muscle spasms and pain reported by the client.

5. When implementing a disaster intervention plan, which intervention should the nurse implement first?

A. Initiate the discharge of stable clients from hospital units
B. Identify a command center where activities are coordinated
C. Assess community safety needs impacted by the disaster
D. Instruct all essential off-duty personnel to report to the facility

Correct answer: B

Rationale: When implementing a disaster intervention plan, the first step the nurse should take is to identify a command center where activities are coordinated. This step is crucial for ensuring an organized and effective disaster response. Option A, initiating the discharge of stable clients, is not a priority during the initial phase of disaster response. Option C, assessing community safety needs, usually follows setting up a command center. Option D, instructing off-duty personnel to report, may be necessary but is not the primary intervention at the beginning of a disaster situation.
