A nurse is assessing a client who is receiving a blood transfusion. The nurse notes lung crackles, hypoxia, and distended neck veins. Which of the following actions should the nurse take? (Select all that apply.)

B. Regular weight-bearing exercises, such as walking, are beneficial for maintaining bone density and strength, which can help prevent osteoporosis. Walking for 30 minutes three to five times per week is a suitable recommendation because it provides consistent moderate-intensity exercise that stimulates bone remodeling and strengthens bones.
A. Water aerobics is a low-impact exercise that is beneficial for overall health and fitness, but it may not provide the same bone-strengthening benefits as weight-bearing exercises like walking.
C. Increasing intake of vitamin B12 is not directly related to osteoporosis prevention. While vitamin B12 is important for overall health and may play a role in bone metabolism, its supplementation is not a primary recommendation for osteoporosis prevention.
D. Maintaining a lean body mass is important for overall health, but it may not directly prevent osteoporosis. While excessive body weight can increase the load on bones and promote bone density, maintaining a healthy body weight through a balanced diet and regular exercise is more important than specifically focusing on lean body mass for osteoporosis prevention.

D. Demonstrates an understanding of safety considerations for an older adult with heart failure. Leaving a light on in the bathroom at night reduces the risk of falls, especially during nocturia (nighttime urination), which is common in heart failure due to fluid retention and diuretic use.
A. Taking a hot bath before bed can increase the risk of dehydration and may exacerbate symptoms of heart failure, as it can lead to further fluid loss through sweating.
B. Regular monitoring of weight is essential for clients with heart failure to assess for fluid retention and worsening heart failure symptoms. Weighing once weekly may not provide timely information to detect changes in fluid status.
C. While the timing of medication administration is important, particularly for diuretics like hydrochlorothiazide, which can increase urination, the optimal timing should be determined based on individual factors and healthcare provider recommendations. It's not specifically indicative of safety considerations related to heart failure and living at home.
