Question 1 of 5
What is the most common side effect of insulin?
Correct Answer: B
Rationale: The most common side effect of insulin therapy is hypoglycemia, which occurs when the blood sugar levels drop too low. Insulin helps lower blood sugar levels by promoting the uptake of glucose into cells, but an excessive dose of insulin or changes in diet and physical activity can lead to hypoglycemia. Symptoms of hypoglycemia may include shakiness, sweating, dizziness, confusion, and hunger. It is important for individuals using insulin to be aware of the signs and symptoms of hypoglycemia and be prepared to treat it promptly with fast-acting glucose sources. Regular monitoring of blood sugar levels can help prevent and manage episodes of hypoglycemia.
Question 2 of 5
Which solution should the nurse administer with packed red blood cells?
Correct Answer: B
Rationale: When administering packed red blood cells, it is recommended to use 0.9% sodium chloride, also known as normal saline solution, as the preferred solution. Normal saline is isotonic and compatible with blood products, making it the most suitable solution for transfusion with packed red blood cells. It helps maintain the osmotic pressure and prevents hemolysis of red blood cells, ensuring the safe delivery of the blood product to the patient. Lactated Ringer's solution, D5W, and 0.45% sodium chloride are not ideal choices for administering packed red blood cells due to their electrolyte compositions and potential risks of adverse reactions.
Question 3 of 5
Which of the following is an amide type of local anesthetics:
Correct Answer: B
Rationale: Articaine is an amide type of local anesthetic. Local anesthetics can be classified into two main categories: esters and amides. Articaine belongs to the amide group of local anesthetics, along with lidocaine, bupivacaine, and others. Amide local anesthetics tend to have longer duration of action and are less likely to cause allergic reactions compared to ester local anesthetics. In the given choices, Procaine, Amethocaine, and Benzocaine are ester-type local anesthetics, while Cocaine is a unique example of a local anesthetic with mixed properties.
Question 4 of 5
A nurse is providing discharge instructions to a patient who is taking atenolol (Tenormin) to treat hypertension. What would the nurse teach the patient regarding a possible drug-drug interaction?
Correct Answer: C
Rationale: A decreased hypertensive effect can occur if a beta-selective adrenergic blocking agent is used in combination with NSAIDs. If this combination is used, the patient should be monitored closely and dosage adjustments made. Antibiotics, oral contraceptives, and antifungal agents are not known to have a drug-drug interaction. The nurse should educate the patient about potential interactions and advise them to consult their healthcare provider before starting any new medications.
Question 5 of 5
Regarding inhaled anaesthetics:
Correct Answer: C
Rationale: Nitrous oxide has a high minimum alveolar concentration (MAC >100%), not low, due to low potency, so that's false. Halogenated agents (e.g., isoflurane) have higher brain:blood coefficients, reflecting solubility, making that false. They reduce mean arterial pressure (MAP) proportional to alveolar concentration via vasodilation, a true statement. Nitrous oxide does decrease tidal volume and increase respiratory rate, true. They don't reduce cerebral metabolic rate via blood flow alone but directly. MAP reduction is a key hemodynamic effect, guiding anesthetic depth monitoring.
