A nurse is reviewing her patient's labs for the shift. She notices that her patient's calcium is 7.8 mg/dl. The nurse can expect to see what assessment findings?
Low Blood Pressure and Dizziness
Edema to the extremities
High temperature and sweating
Positive Chvostek's Sign and Anxiety
The Correct Answer is D
A. Low Blood Pressure and Dizziness: Low blood pressure and dizziness are more commonly associated with other conditions such as dehydration or blood loss. Hypocalcemia may cause symptoms like muscle cramps or tingling but not typically low blood pressure.
B. Edema to the extremities: Edema is often related to conditions such as heart failure, kidney disease, or inflammation, not directly to low calcium levels. Hypocalcemia does not typically present with edema in the extremities, so this is not a likely finding.
C. High temperature and sweating: High temperature and sweating are not characteristic of hypocalcemia. These symptoms are more often seen with fever, infection, or hyperthyroidism, not with low calcium levels, which usually cause neuromuscular symptoms.
D. Positive Chvostek's Sign and Anxiety: A calcium level of 7.8 mg/dL is low, and hypocalcemia can cause neuromuscular irritability, including a positive Chvostek's sign. Anxiety is also common in hypocalcemia due to its effect on the nervous system.

Correct Answer is C
Explanation
A. Increased balance: Aging typically results in decreased balance due to changes in the musculoskeletal and nervous systems. Older adults often experience a decline in coordination and proprioception, which can increase the risk of falls.
B. Increased muscle mass: Muscle mass generally decreases with age, a condition known as sarcopenia. This loss contributes to reduced strength and endurance, making physical activity and mobility more difficult for older adults.
C. Increased joint stiffness: Joint stiffness is a common age-related change caused by decreased synovial fluid, cartilage wear, and reduced flexibility. This can limit mobility and make daily activities more challenging for elderly clients.
D. Increased calcification of bones: With aging, bones tend to lose density and become more porous, leading to conditions like osteoporosis. Calcification may occur in soft tissues, but bone itself typically becomes weaker, not more calcified.
Correct Answer is B
Explanation
A. stage 4 pressure injury: A stage 4 pressure injury involves full-thickness skin and tissue loss with exposed bone, tendon, or muscle, which is beyond subcutaneous tissue damage. These wounds may also include undermining or tunneling and carry a high risk for infection.
B. stage 3 pressure injury: Stage 3 pressure injuries involve full-thickness skin loss that extends into the subcutaneous tissue but does not expose bone, tendon, or muscle, aligning with the description of the wound. This stage may also include slough, undermining, or tunneling.
C. stage 2 pressure injury: A stage 2 injury involves partial-thickness skin loss with exposure of the dermis, typically presenting as a shallow open ulcer, not reaching subcutaneous layers. It may also appear as an intact or ruptured serum-filled blister.
D. stage 1 pressure injury: Stage 1 is characterized by non-blanchable erythema of intact skin without any tissue loss or damage to deeper layers.
