Correct Answer: C

Rationale: In clients with dementia and difficulty communicating, using behavioral indicators such as agitation and restlessness is more reliable for assessing pain than relying on verbal self-report, pain scales, or observing facial expressions. Verbal self-report may not be possible due to communication challenges, pain scales may be difficult for the client to comprehend, and observing facial expressions alone may not provide a comprehensive assessment of pain in individuals with dementia.

Correct Answer: C

Rationale: The correct answer is C: 'Avoid open flames or smoking near oxygen.' This information is crucial to prevent fires because oxygen supports combustion. Choices A, B, and D are incorrect. Choice A is not relevant to oxygen therapy. Choice B is incorrect as oxygen should not be turned off when in use as prescribed.

Rationale: The ventrogluteal site is the preferred site for intramuscular injections to avoid injury to nerves or blood vessels. The deltoid site is commonly used for vaccines but has a higher risk of hitting the radial nerve. The rectus femoris site is not typically recommended for intramuscular injections. The dorsogluteal site is contraindicated due to the proximity to the sciatic nerve and major blood vessels.

Correct Answer: A

Rationale: The correct answer is A: Negligence. Negligence in nursing occurs when a healthcare provider fails to take appropriate action that a reasonably prudent provider would take in a similar situation, such as not notifying the provider of changes in a client's condition. In this scenario, the nurse's failure to inform the provider of the client's changed condition constitutes negligence. Choices B, C, and D are incorrect. Assault involves the intentional threat of bodily harm to another person, battery is the intentional harmful or offensive touching of another person without their consent, and defamation is the act of making false statements about someone to a third party that harms that person's reputation.

Correct Answer: A

Rationale: Bladder distention is the correct finding that indicates a catheter occlusion. When the catheter is occluded, urine cannot drain properly, leading to the build-up of urine in the bladder, causing distention. Bladder spasms (Choice B) are not typically associated with catheter occlusion but may indicate irritation or infection. Hematuria (Choice C) refers to blood in the urine and is not specific to catheter occlusion. Increased urine output (Choice D) is not indicative of catheter occlusion but may suggest other conditions like diabetes insipidus.
