When a person first begins drinking alcohol, two drinks produce relaxation and drowsiness. After 1 year, four drinks are needed to achieve the same relaxed, drowsy state. Why does this change occur?

Correct Answer: B

Rationale: The correct answer is B: Tolerance develops. Tolerance occurs when the body adapts to repeated exposure to alcohol, requiring higher doses to achieve the same effect. Initially, two drinks were sufficient, but over time, the body adjusts, leading to the need for four drinks to achieve the same level of relaxation and drowsiness. This change is not due to the alcohol being less potent (A), antagonistic effects (C), or hypomagnesemia (D). Tolerance is a well-documented phenomenon in the context of alcohol consumption, explaining the increased amount needed to achieve the desired effect.

Correct Answer: D

Rationale: The correct answer is D: Drowsiness, constricted pupils, slurred speech. After injecting heroin, the individual experiences a rapid onset of effects due to the drug's ability to quickly cross the blood-brain barrier. The central nervous system is depressed, leading to drowsiness and sedation. Heroin causes constriction of the pupils (miosis) due to its effect on the autonomic nervous system. The individual may also exhibit slurred speech due to the drug's impact on cognitive and motor functions. Incorrect Choices: A: Anxiety, restlessness, paranoid delusions - These symptoms are more commonly associated with stimulant drugs like cocaine or amphetamines. B: Heightened sexuality, insomnia, euphoria - These effects are more commonly seen with stimulant drugs rather than heroin. C: Muscle aching, dilated pupils, tachycardia - Muscle aching and tachycardia are signs of opioid withdrawal rather than immediate effects of heroin use. Dil

Correct Answer: C

Rationale: The correct answer is C: A synergistic effect occurs. When alcohol is consumed with pentobarbital sodium, both substances depress the central nervous system. This results in an enhanced sedative effect, leading to respiratory depression, coma, and potentially death. The combined effect of the two substances is greater than the sum of their individual effects. Choices A and B are incorrect as alcohol does not stimulate the metabolism of pentobarbital sodium nor diminish its effect. Choice D is also incorrect as there is a significant effect when alcohol is combined with this drug.

Correct Answer: D

Rationale: The correct answer is D because confusion, mouth ulcers, and ataxia are common assessment findings in individuals who have been using inhalants. Confusion and ataxia are neurological symptoms associated with inhalant use, while mouth ulcers can result from the toxic effects of inhalants on oral mucosa. These findings indicate central nervous system depression and potential damage from inhalant exposure. Choices A, B, and C are incorrect because they do not align with typical assessment findings of inhalant use. Perforated nasal septum and hypertension (A) are more commonly associated with chronic cocaine use. Drowsiness, euphoria, and constipation (B) are symptoms of opioid use. Pinpoint pupils and respiratory rate of 12 breaths per minute (C) are indicative of opioid overdose, not inhalant use.

Correct Answer: C

Rationale: The correct answer is C because asking a client to explain his or her cultural beliefs regarding the role of women demonstrates an understanding of the importance of value clarification. By exploring the client's cultural beliefs, the nurse shows respect for the client's values and perspectives, which is essential for building a therapeutic relationship. This action also promotes cultural competence and helps the nurse understand the client's worldview. Choice A is incorrect because although intently listening is important, it does not specifically address value clarification. Choice B is incorrect because arranging for the chaplain's visit may be helpful but does not directly relate to value clarification. Choice D is incorrect as encouraging the client to read a newspaper article on political issues does not necessarily focus on the client's values or beliefs.
