Pelvic rocking exercises can help relieve lower back pain during pregnancy. The client can perform this exercise by getting on their hands and knees, keeping their back straight, and gently rocking their pelvis back and forth. This helps to stretch and strengthen the muscles in the lower back and pelvis.

A. Sit in a hot tub for 30 min every evening: Hot tubs and hot baths are not recommended during pregnancy as they can raise the body temperature too high, which can be harmful to the developing fetus.
B. Raise chairs to keep knees lower than hips: This recommendation is more appropriate for promoting good posture and reducing strain on the back, but it may not specifically address lower back pain.
C. Use the arms to pick up heavy items: It is important to avoid heavy lifting during pregnancy as it can strain the back and increase the risk of injury. It is recommended to use proper lifting techniques, such as bending the knees and using the leg muscles rather than the back muscles, to lift objects.

Hypertensive crisis is a severe increase in blood pressure that can lead to organ damage or other complications. Prompt assessment and intervention are necessary to prevent further escalation of blood pressure and potential complications.

While all the clients mentioned require attention, the client with elevated blood pressure and a headache poses a higher immediate risk. The nurse should assess the client's blood pressure, evaluate for signs of target organ damage, and initiate appropriate interventions, which may include administering antihypertensive medications as prescribed and monitoring closely for any changes in the client's condition.

The client who is postoperative and reports intermittent nausea can be assessed and managed after addressing the client with the elevated blood pressure and headache.
