A nurse is caring for an elderly client diagnosed with a urinary tract infection (UTI). The family reports an abrupt onset of altered mental status, disorientation, and intermittent hallucinations. The nurse would identify these signs to be consistent with which sensory alteration?

Sleep deprivation

Normal signs of aging

Dementia

Delirium

Answer and Explanation

The Correct Answer is D

Choice A Reason:

Sleep deprivation is incorrect. While sleep deprivation can cause confusion and disorientation, it is less likely to cause abrupt onset of altered mental status and hallucinations. Sleep deprivation typically results in gradual cognitive decline and fatigue rather than sudden changes.

Choice B Reason:

Normal signs of aging is incorrect. Normal aging can involve some cognitive decline, but it does not typically cause sudden and severe symptoms like hallucinations and significant disorientation. These symptoms are more indicative of an acute condition.

Choice C Reason:

Dementia is incorrect. Dementia involves a gradual decline in cognitive function over time and does not typically present with sudden onset of symptoms. While dementia can include hallucinations and disorientation, these symptoms usually develop progressively.

Choice D Reason:

Delirium is correct. Delirium is characterized by a sudden onset of confusion, disorientation, and changes in mental status. It is often triggered by acute medical conditions such as infections, including UTIs. Elderly patients are particularly susceptible to delirium, which can include symptoms like hallucinations and severe confusion.

Correct Answer is D

Explanation

Choice A Reason:

“Delivers a low concentration of oxygen” is incorrect because a nasal cannula can deliver varying concentrations of oxygen depending on the flow rate set by the healthcare provider. The concentration can range from low to moderate, typically between 24% to 44%.

Choice B Reason:

“Delivers a constant rate of oxygen” is partially correct but not entirely accurate. While the flow rate can be constant, the key aspect is the specific concentration of oxygen delivered, which is more relevant to the client’s understanding.

Choice C Reason:

“Delivers a high concentration of oxygen” is incorrect because nasal cannulas are generally used for low to moderate oxygen delivery. High concentrations of oxygen are typically delivered through other devices like non-rebreather masks or high-flow nasal cannulas.

Choice D Reason:

“Delivers a constant flow of a specific concentration of oxygen” is correct. This explanation accurately describes how a nasal cannula works. It provides a continuous flow of oxygen at a specific concentration, which is adjusted based on the client’s needs and the healthcare provider’s prescription.

A. Defamation of character B. Invasion of privacy C. Slander D. False imprisonment

Correct Answer is D

Explanation

Choice A Reason:

Defamation of character is incorrect. Defamation of character involves making false statements about someone that damage their reputation. This can be in the form of slander (spoken) or libel (written). Applying restraints without proper justification does not fall under defamation of character.

Choice B Reason:

Invasion of privacy is incorrect. Invasion of privacy involves intruding into someone’s personal life without consent. This can include unauthorized access to personal information or spaces. Applying restraints without proper justification is not an invasion of privacy.

Choice C Reason:

Slander is incorrect. Slander is a form of defamation that involves making false spoken statements that damage someone’s reputation. Applying restraints without proper justification does not involve making false statements.

Choice D Reason:

False imprisonment is correct. False imprisonment involves restraining a person without legal justification or their consent. In a healthcare setting, applying restraints without proper justification or following legal and ethical guidelines constitutes false imprisonment and violates the client’s rights.
