The nursing caring for a patient who is receiving Warfarin. The lab calls and tells the nurse the patient's INR is reported at 5.3. What action should the nurse take?

A. All complementary and alternative therapies are safe to use along with insulin.: Not all complementary or alternative therapies are safe for patients taking insulin. Some may affect blood glucose levels or interact with insulin, potentially causing hypoglycemia or hyperglycemia. Patients should always discuss any supplements with their healthcare provider.

B. Wash your hands prior to insulin administration.: Proper hand hygiene reduces the risk of infection at the injection site and prevents contamination of the insulin vial or syringe. This is a key safety practice in self-administration of insulin.

C. Unopened insulin vials should be stored in the refrigerator.: Storing unopened insulin in the refrigerator preserves its potency until the expiration date. Exposure to heat or direct sunlight can degrade the insulin, reducing its effectiveness.

D. With diet and exercise you may be able to stop taking insulin.: Type 1 diabetes requires lifelong insulin therapy because the pancreas produces little to no insulin. Diet and exercise alone cannot replace the need for insulin. Stopping insulin could lead to life-threatening hyperglycemia or diabetic ketoacidosis.

E. You will need to monitor your glucose more often when you are ill.: Illness can cause stress-induced hyperglycemia and unpredictable blood glucose fluctuations. Frequent monitoring allows timely adjustment of insulin and prevention of complications such as diabetic ketoacidosis.

A. Albuterol is an anticholinergic causing dryness of bronchial secretions: Albuterol does not have anticholinergic properties and does not reduce secretions. Its primary action is bronchodilation, not secretion management.

B. Albuterol stimulates the parasympathetic nervous system causing the heart rate to decrease.: Albuterol is not a parasympathetic stimulant and can actually cause mild tachycardia due to beta-1 effects. Decreasing heart rate is not part of its therapeutic action in asthma.

C. Albuterol is a beta 2 adrenergic agonist which relaxes bronchial smooth muscle.: Albuterol selectively activates beta-2 receptors in the airways, causing smooth muscle relaxation and bronchodilation. This prevents exercise-induced bronchospasm and improves airflow, making it the first-line rescue medication for asthma.

D. Albuterol is an antihistamine, causing a block in the histamine response.: Albuterol does not block histamine receptors and does not prevent allergic responses. Its mechanism targets beta-2 adrenergic receptors to dilate airways, not histamine pathways.
