1. An increase in the neurotransmitter dopamine is associated with which of the following illnesses?

• A. Schizophrenia
• B. Depression
• C. Alzheimer's disease
• D. Anxiety

Correct answer: A

Rationale: An increase in the neurotransmitter dopamine is associated with schizophrenia. Dopamine dysregulation is linked to some symptoms of schizophrenia, such as hallucinations and delusions. Depression (choice B) is more commonly associated with abnormalities in serotonin and norepinephrine. Alzheimer's disease (choice C) is primarily characterized by deficits in acetylcholine and other neurotransmitters. Anxiety disorders (choice D) are often linked to imbalances in neurotransmitters like serotonin, norepinephrine, and GABA, rather than dopamine.

2. Which behavioral characteristic describes the domestic abuser?

• A. Alcoholic
• B. Overconfident
• C. High tolerance for frustrations
• D. Low self-esteem

Correct answer: D

Rationale: The correct answer is 'Low self-esteem.' Domestic abusers often exhibit behaviors stemming from their own experiences of abuse, leading to a cycle of violence. They commonly have low self-esteem, which drives their need to exert control and power over their partners. Choice A, 'Alcoholic,' is not a defining behavioral characteristic of domestic abusers. Choice B, 'Overconfident,' is not typically associated with abusers who often exhibit insecurity and control issues. Choice C, 'High tolerance for frustrations,' is not a primary characteristic of domestic abusers; rather, they often have a low tolerance for situations that challenge their need for control.

3. Which of the following is an example of non-reversible dementia?

• A. Pick's disease
• B. Syphilis
• C. Encephalopathy
• D. Hyperthyroidism

Correct answer: A

Rationale: Non-reversible dementia refers to a condition where individuals experience permanent and often progressive cognitive decline. Pick's disease is a type of non-reversible dementia characterized by changes in personality, behavior, and language difficulties. Syphilis (Choice B) is a reversible cause of dementia that can be treated with antibiotics. Encephalopathy (Choice C) is a broad term for brain dysfunction that can be reversible or irreversible depending on the cause. Hyperthyroidism (Choice D) can lead to cognitive impairment but is reversible with appropriate treatment. Therefore, Pick's disease is the correct example of non-reversible dementia among the options provided.

4. The parents of a child often try to persuade their preschooler to touch their pet dog to reduce the child's fear of dogs. Instead, the child's fears and anxiety increase. Which advice would the nurse suggest to help overcome their child's fear?

• A. Ask the child to touch the dog's back gently.
• B. Keep the child away from dogs for a few years.
• C. Let the child watch other children playing with dogs.
• D. Bring in a pet cat to familiarize the child with animals.

Correct answer: C

Rationale: To help the child overcome their fear of dogs, the nurse should recommend letting the child watch other children playing with dogs. This approach allows the child to observe interactions with dogs in a safe environment, gradually building comfort and familiarity. Encouraging the child to touch the dog's back gently may increase fear and anxiety, as it could be overwhelming for the child. Keeping the child away from dogs for a few years does not address the fear directly and may not help the child overcome it. Bringing in a pet cat, while introducing the child to animals, does not specifically target the fear of dogs and may not effectively reduce the fear and anxiety associated with dogs.

5. The nurse is preparing to administer 10 mL of liquid potassium chloride through a feeding tube, followed by 10 mL of liquid acetaminophen. Which action should the nurse include in this procedure?

• A. Dilute each of the medications with sterile water prior to administration.
• B. Mix the medications in one syringe before opening the feeding tube.
• C. Administer water between the doses of the two liquid medications.
• D. Withdraw any fluid from the tube before instilling each medication.

Correct answer: C

Rationale: Water should be instilled into the feeding tube between administering the two medications to maintain the patency of the feeding tube and ensure that the total dose of medication enters the stomach and does not remain in the tube. These liquid medications do not need to be diluted when administered via a feeding tube. Mixing the medications in one syringe can lead to interactions or alterations in the medications' properties. Withdrawing any fluid from the tube before instilling each medication can cause inaccurate dosing and incomplete administration. Therefore, the correct action is to administer water between the doses of the two liquid medications to ensure proper delivery and avoid any complications.
