A nurse is planning to teach a group of newly licensed nurses about hypermagnesemia. Which of the following manifestations should the nurse include in the teaching?
Bradypnea
Personality change
Seizure
Elevated hematocrit
The Correct Answer is A
A. Bradypnea: Hypermagnesemia depresses neuromuscular and central nervous system function, which can lead to slowed respiratory rate (bradypnea) and potentially respiratory failure in severe cases.
B. Personality change: Personality changes are more commonly associated with hyponatremia, hypernatremia, or other electrolyte imbalances affecting the brain, rather than hypermagnesemia.
C. Seizure: Seizures are more likely in hypomagnesemia due to increased neuromuscular excitability, not in hypermagnesemia, which generally causes neuromuscular depression.
D. Elevated hematocrit: Hypermagnesemia does not directly affect red blood cell concentration or hematocrit levels. Changes in hematocrit are usually related to fluid volume status, not magnesium levels.

Correct Answer is C
Explanation
A. "You will be given access to the medical records of every client in the facility.": Access to electronic medical records is restricted based on the nurse’s role and need-to-know basis to protect client confidentiality. Nurses only view records of clients under their care.
B. "You will be asked to change your password once per year.": Most facilities require more frequent password changes, often every 60–90 days, to maintain system security. Annual changes alone are insufficient for protecting client data.
C. "Information Technology will install a firewall to secure client information.": Firewalls and other cybersecurity measures help protect electronic health information from unauthorized access. Including this ensures nurses understand that the system has built-in technical safeguards for privacy and security.
D. "Documentation of sensitive material is performed by the charge nurse.": All licensed nurses are responsible for accurate, complete, and timely documentation of client care, including sensitive material. Responsibility is not limited to the charge nurse.
Correct Answer is B
Explanation
Rationale:
A. Dietitian: A dietitian focuses on nutritional needs, which may be beneficial if the client has dietary concerns, but this does not directly address mobility issues related to lower extremity weakness.
B. Physical therapy: Physical therapists specialize in improving strength, balance, and mobility. A referral will help the client develop exercises and strategies to enhance function and reduce fall risk.
C. Case manager: A case manager coordinates healthcare services, but they do not directly provide rehabilitation for weakness. They may be involved later to arrange additional resources after therapy needs are determined.
D. Social services: Social services assist with psychosocial needs, financial support, and community resources, but they are not the primary referral for addressing physical mobility limitations.
