Correct Answer: C

Rationale: Cold extremities are a critical sign of impending death as they indicate decreased circulation, leading to poor perfusion to the extremities. This phenomenon occurs as the body redirects blood flow to vital organs, preparing for the end of life. Hypertension and tachycardia are less likely to be seen in the terminal phase and are usually associated with other conditions like shock or sepsis. Diaphoresis, or excessive sweating, may occur in various situations but is not a specific indicator of impending death in this context.

Correct Answer: A

Rationale: The correct answer is A, paradoxical excitement. Lorazepam can cause an unexpected response of paradoxical excitement, which should be reported to the healthcare provider. This reaction is characterized by increased anxiety, restlessness, and agitation instead of the expected calming effect. Choices B, C, and D are incorrect because headache, slowing of reflexes, and fatigue are more common side effects of lorazepam and may not warrant immediate reporting unless severe or persistent.

Correct Answer: D

Rationale: The correct answer is D because having family members wear a gown and gloves when visiting a client with Clostridium difficile is essential to prevent the spread of infection. Options A, B, and C are incorrect. Negative air-flow systems are not necessary for preventing the spread of C. difficile. While alcohol-based hand sanitizers are effective for routine hand hygiene, they may not be sufficient for C. difficile. Cleaning contaminated surfaces with a phenol solution is not the most effective method for preventing the spread of C. difficile, as spores can be resistant to many disinfectants.

Correct Answer: A

Rationale: The correct answer is A: Crush medications and mix with food. When administering oral medications to a patient with dysphagia, crushing the medications and mixing them with food is a common method to aid in swallowing. Choice B is incorrect because using a straw could pose a choking hazard for patients with dysphagia. Choice C is incorrect as thickened liquids may not always be suitable for all medications. Choice D is incorrect because having the patient lie flat can increase the risk of aspiration, which is not recommended for patients with dysphagia.

Correct Answer: C

Rationale: When caring for a client diagnosed with delirium, the most important condition for the nurse to investigate is prescription drug intoxication. Delirium can be caused by various factors, and prescription drug intoxication is a common reversible cause. Investigating this factor first is crucial to identify and address the underlying cause promptly. Choices A, B, and D are less likely to be directly associated with delirium compared to prescription drug intoxication. While cancer, impaired hearing, and heart failure can have their complications and effects, they are not typically the primary causes of delirium in a client.
