Correct Answer: B

Rationale: The correct position for a lumbar puncture is the lateral recumbent position. This position allows the spine to curve naturally, widening the spaces between the vertebrae, making it easier and safer to perform the procedure. Supine with head elevated (Choice A) would not provide the proper positioning for a lumbar puncture as it does not allow for proper access to the lumbar area. Prone with arms at sides (Choice C) would not be suitable as it would not facilitate the procedure. Sitting with back rounded (Choice D) is also incorrect as it does not allow for the proper alignment of the spine needed for a lumbar puncture.

Correct Answer: D

Rationale: After surgery, key signs of infection include redness, swelling, and fever. Redness and swelling can indicate inflammation at the surgical site, while fever is a systemic response to infection. Choosing 'All of the above' (Option D) is the correct answer because all three signs are commonly associated with post-surgical infections. Options A, B, and C are incorrect as each of them individually can be a sign of infection, but considering all three together provides a more comprehensive assessment for post-operative infection.

Correct Answer: D

Rationale: Avoiding sun exposure is crucial to prevent skin irritation and burns in clients undergoing radiation therapy. Radiation therapy makes the skin more sensitive to sunlight, increasing the risk of skin damage. Applying heat packs (choice A) can exacerbate skin irritation as heat can further irritate the skin that is already sensitive due to radiation. Using perfumed soap (choice B) can further irritate the skin due to its harsh chemicals, potentially worsening skin reactions. While keeping the area moist with lotion (choice C) may seem beneficial, some lotions contain ingredients that can worsen skin reactions during radiation therapy. Therefore, avoiding sun exposure to the treated area (choice D) is the most appropriate action to prevent skin irritation and damage during radiation therapy.

Correct Answer: B

Rationale: When caring for a client diagnosed with bipolar disorder, the priority is to monitor for signs of depression. Individuals with bipolar disorder are at risk of severe depressive episodes, making it crucial to watch for signs of depression. While changes in energy levels and self-esteem are common in bipolar disorder, they are not the primary focus. Hyperactivity is a characteristic of the manic phase of bipolar disorder, so monitoring for depression is the priority in this case.

Correct Answer: D

Rationale: The correct answer is to keep the oxygen equipment at least 6 feet away from heat sources. Placing oxygen equipment near heat sources can lead to fire hazards due to the oxygen's combustible nature. Option A is the correct safety measure as smoking near oxygen equipment can cause fires due to oxygen's flammable properties. Option B regarding the use of non-flammable bedding is not directly related to oxygen safety. Option C is important for proper oxygen tank functioning but is not as critical as keeping the equipment away from heat sources to prevent fires.
