Rationale: Continuing Professional Development such as post-graduate study is the best strategy among the options provided for addressing short staffing in the hospital. By encouraging nurses to pursue post-graduate studies, Chief Nurse Cirila is investing in the long-term growth and development of her nursing workforce. Post-graduate studies can enhance the knowledge, skills, and expertise of nurses, making them more competent in their roles. This can lead to improved patient care outcomes, increased job satisfaction among nurses, and ultimately help in retaining and attracting talent in the hospital. Additionally, supporting nurses in their professional development can boost morale and motivation, which are crucial factors in addressing short staffing issues.

Rationale: Carpal tunnel syndrome is a condition caused by compression of the median nerve in the wrist. The surgical procedure commonly performed to treat carpal tunnel syndrome is called median nerve release or carpal tunnel release. During this surgery, the transverse carpal ligament is divided to relieve pressure on the median nerve, reducing symptoms such as pain, numbness, and tingling in the hand and fingers. The goal of this procedure is to improve nerve function and reduce symptoms associated with carpal tunnel syndrome.

Correct Answer: C

Rationale: The most appropriate response by the nurse is, "If I were you, I will get a second opinion." This response acknowledges the seriousness of the situation and the life-changing decision the patient has been told to make. Suggesting the patient seek a second opinion is essential as it encourages the patient to explore all options and ensures they have considered all possibilities before proceeding with a major surgery like an above-the-knee amputation. It shows the nurse's support for the patient while also advocating for the patient's right to make an informed decision about their healthcare.

Correct Answer: A

Rationale: Bulimia nervosa is an eating disorder characterized by binge eating followed by compensatory behaviors such as self-induced vomiting, fasting, or excessive exercise. The repeated purging in bulimia can lead to electrolyte imbalances, such as hypokalemia (low potassium levels). Hypokalemia is a serious condition that can affect the function of the heart's electrical system, potentially leading to the development of cardiac arrhythmias (irregular heartbeats) and even cardiac arrest, which can result in death. Therefore, in a bulimic patient like Sherry, the risk of death is most likely due to the combination of hypokalemia and its complications, such as cardiac arrhythmias and arrest.
