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 bathing an uncircumcised boy older than 3 years, it is essential to gently retract the foreskin to cleanse the penis. This helps in preventing the buildup of bacteria and maintaining good hygiene. Reminding the child to clean his genital area (Option A) may not be effective due to the child's cognitive development level. Perineal care should not be deferred (Option B) as it is necessary for maintaining hygiene at any age. Asking the parents why the child is not circumcised (Option D) is not relevant to the immediate care required during bathing.

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.

Correct Answer: D

Rationale: Health care providers may be found guilty of negligence, specifically assault and battery, if they carry out a treatment without the client's consent. The client's condition is stable, so the family cannot provide consent without her involvement, making option A incorrect. There is no evidence of mental incompetence in the client, so the son cannot waive informed consent, making option B incorrect. While therapeutic privilege may have been accepted in the past, it is unlikely to be upheld by today's courts, making option C incorrect. It is crucial for health care providers to obtain informed consent from clients before proceeding with any treatment to avoid legal consequences and uphold ethical standards.

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.
