Correct Answer: A

Rationale: The client is exhibiting normal grieving behaviors, so referral to a grief counselor is the most important intervention for the nurse to implement. Option B is relevant but is not a high-priority intervention compared to addressing the immediate grief support needs of the client. Option C is irrelevant at this time but might be important when determining the client's risk for contracting the illness. While antidepressant medication might be necessary based on further assessment, grief counseling is a more appropriate initial action as grief is a typical response to the loss of a loved one.

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.

Correct Answer: A

Rationale: Barbiturates cause central nervous system (CNS) depression, increasing the risk of falls. Therefore, the nurse should assist the client to the bathroom to ensure safety. Using a bedpan is not necessary if the client can safely walk to the bathroom. Asking about bowel movements or voiding, as in option C, is irrelevant to the immediate safety concern of assisting the client to the bathroom. Assessing the client's bladder, as in option D, is unnecessary in this situation as there is no indication that the client cannot communicate his or her needs effectively. The priority here is to prevent falls and ensure the client's safety while assisting to the bathroom.

Correct Answer: D

Rationale: Group therapy is a valuable approach in mental health treatment. Working with psychiatric clients in a group setting offers various benefits. Clients in a group setting can learn from others when their behaviors are inappropriate in a safe and trusting environment. This environment allows individuals to express thoughts and feelings without fear of judgment or criticism, fostering a supportive atmosphere. Through interactions with peers, clients can gain insight into their own behaviors and learn alternative ways of coping. Choice A is incorrect as the presence and support of a nurse are typically important in group therapy sessions. Choice B is incorrect as group settings provide structure and rules to ensure a safe space for clients to express themselves. Choice C is incorrect as maintaining confidentiality is crucial in group therapy to build trust and encourage open sharing.

Correct Answer: C

Rationale: When no urine is seen in the tubing after inserting a catheter in a female client who has not voided for 8 hours, it is possible that the catheter is in the vagina rather than the bladder. Leaving the initial catheter in place can help locate the meatus for the second attempt. The client should have at least 240 mL of urine output after 8 hours, indicating the need for catheterization. Clamping the catheter (Option A) does not address the issue of incorrect catheter placement. Pulling the catheter back and redirecting it (Option B) is not effective unless the catheter is completely removed, requiring a new catheter. There is no indication of a urinary tract obstruction to notify the healthcare provider (Option D) as the catheter could be inserted easily.
