A nurse is providing care to a client who has a history of asthma. The client presents with influenza symptoms that started the previous day. The provider orders an influenza test and prescribes an oral antiviral with instructions to begin the treatment as soon as possible. The client asks the nurse whether they can take the antiviral before the lab results are back. Which of the following responses by the nurse is appropriate?

A. The client who has renal failure: Renal failure can lead to hypocalcemia due to the kidneys' reduced ability to convert vitamin D to its active form, leading to decreased calcium absorption.

B. The client who is postoperative following a thyroidectomy: Hypocalcemia can occur after thyroidectomy if the parathyroid glands are inadvertently damaged or removed, as they regulate calcium levels.

C. The client who has hyperparathyroidism: Hyperparathyroidism typically leads to hypercalcemia, not hypocalcemia, as excessive parathyroid hormone (PTH) increases calcium levels in the blood.

D. The client who has vitamin D deficiency: Vitamin D is essential for calcium absorption in the intestines, so a deficiency can lead to hypocalcemia.

E. The client who is receiving bisphosphonate medications: Bisphosphonates inhibit bone resorption, which can lead to a decrease in calcium levels, potentially causing hypocalcemia.

F. The client who has Addison's disease: Addison's disease is primarily associated with electrolyte imbalances like hyponatremia and hyperkalemia, not hypocalcemia.

A. The "Choice of Analgesia and Sedation" component of the ABCDEF assessment tool focuses on selecting appropriate pain relief and sedation strategies for the patient but does not directly relate to the weaning process.
B. "Assess, Prevent, and Manage Pain" involves ensuring the patient is comfortable and free from pain, which is important but not specifically related to weaning from the ventilator.
C. "Delirium: Assess, Prevent, and Manage" addresses the cognitive status of the patient, particularly the prevention and management of delirium, which is a critical aspect of care but not directly related to ventilator weaning.
D. "Breathing: Spontaneous Awakening Trials (SAT) and Spontaneous Breathing Trials (SBT)" directly involves the weaning process, as it includes assessing the patient's ability to breathe independently by reducing or removing sedation (SAT) and evaluating their capacity for spontaneous breathing (SBT).
