Correct Answer: D

Rationale: The correct answer is 'High risk for infection.' When caring for a client with an indwelling urinary catheter, the highest priority is to prevent infections, as these catheters are a significant source of infection. Options A and B, self-care deficit and functional incontinence, may be concerns but are not directly related to the indwelling catheter. Option C, fluid volume deficit, is not typically associated with the presence of an indwelling urinary catheter.

Correct Answer: D

Rationale: Opioids are a type of drug classified as narcotics. Nurses working with clients with substance abuse issues often encounter opioids. Opioids have the potential for addiction. Examples of opioids include methadone, codeine, morphine, and hydromorphone. Mescaline (Choice A) is a hallucinogen, not an opioid. Diazepam (Choice B) is a benzodiazepine used to treat anxiety and other conditions, not an opioid. Phenobarbital (Choice C) is a barbiturate used to treat seizures and insomnia, not an opioid.

Correct Answer: C

Rationale: When the nurse is unable to distinguish the point at which the first sound was heard while taking a client's blood pressure, the best action is to deflate the cuff to zero and wait 30 to 60 seconds before reattempting the reading. Deflating the cuff for this duration allows blood flow to return to the extremity, ensuring an accurate reading on that extremity a second time. Option A of deflating the cuff completely and immediately reattempting the reading could lead to a falsely high reading. Option B, re-inflating the cuff completely and leaving it inflated for 90 to 110 seconds, reduces circulation, causes pain, and may alter the reading. Option D, documenting the exact level visualized on the sphygmomanometer where the first fluctuation was seen, is not a reliable method for assessing blood pressure and does not address the issue of obtaining an accurate reading.

Correct Answer: C

Rationale: When dealing with an angry client, it is crucial to employ techniques that can help de-escalate the situation or ensure safety while providing care. If the client's behavior is escalating or they are fixating on a particular topic that is fueling their anger, it is advisable to temporarily change the subject. This technique can serve as a distraction from the initial trigger, allowing the client to refocus their thoughts and emotions. Placing a hand on the client's shoulder may not be well-received as physical touch can escalate the situation. Maintaining close proximity might be perceived as confrontational rather than building trust. Closing the door for privacy is important but may not directly address the client's anger or help in de-escalation.

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.
