Correct Answer: A

Rationale: Abdominal cramping is a common manifestation of hyponatremia (low sodium levels). When sodium levels drop, it can lead to changes in the body's water balance, affecting cell function and causing symptoms like abdominal cramping. Increased thirst (choice B) is more commonly associated with hypernatremia (high sodium levels) due to the body's attempt to dilute the excess sodium. Elevated blood pressure (choice C) and elevated heart rate (choice D) are not typically direct manifestations of low sodium levels and are more commonly seen in conditions like dehydration or shock.

Correct Answer: B

Rationale: Depressed clients are at the highest risk of attempting suicide 7 to 14 days after starting antidepressant medication and psychotherapy. During this time, they may start to regain energy but still feel hopeless, which can increase the risk of suicidal ideation and behavior. Choices A, C, and D are incorrect because immediate post-admission, after an angry outburst with family, or when removed from a security room are not specific periods known to be associated with the highest risk of suicide in depressed clients.

Correct Answer: D

Rationale: The correct response is to involve the client's religious and spiritual leaders in the discussion to find a solution that respects both the client's values and medical needs. Option A is incorrect as it dismisses the client's beliefs. Option B assumes the family's opinion over the client's. Option C is inappropriate as it questions the client's religious beliefs rather than addressing the concern respectfully.

Correct Answer: A

Rationale: A pull toy is the most appropriate choice for an 18-month-old child. At this age, children are developing their motor skills and coordination, and a pull toy can help with these aspects by encouraging movement and coordination. Puzzle with large pieces (Choice B) may pose a choking hazard for a child of this age due to small parts. While a book with large pictures (Choice C) can be engaging and beneficial for language development, a pull toy is more suitable for promoting physical development in an 18-month-old. A doll with small clothes (Choice D) is not ideal for this age group as small parts can be a choking hazard.

Correct Answer: A

Rationale: The correct answer is to regulate O2 via nasal cannula no more than 6L. This flow rate is generally recommended to ensure adequate oxygen delivery without causing discomfort or potential harm to the patient. Choices B, C, and D are incorrect as they suggest flow rates that are either too low (2L, 4L) or too high (8L). A flow rate of 2L might not provide sufficient oxygen, while 4L could be inadequate for some patients. On the other hand, a flow rate of 8L could be excessive and potentially harmful, leading to complications like oxygen toxicity. Therefore, the optimal recommendation is to regulate O2 via nasal cannula at a maximum of 6L to balance effectiveness and safety.
