1. An external insulin pump is prescribed for a client with DM. The client asks the nurse about the functioning of the pump. The nurse bases the response on the information that the pump:
- A. Gives small continuous doses of regular insulin subcutaneously, and the client can self-administer a bolus with an additional dosage from the pump before each meal.
- B. Is timed to release programmed doses of regular or NPH insulin into the bloodstream at specific intervals.
- C. Is surgically attached to the pancreas and infuses regular insulin into the pancreas, which in turn releases the insulin into the bloodstream.
- D. Continuously infuses small amounts of NPH insulin into the bloodstream while regularly monitoring blood glucose levels.
Correct answer: A
Rationale: The correct answer is A. An external insulin pump delivers small continuous doses of regular insulin subcutaneously throughout the day to meet the basal insulin needs. The client can also self-administer a bolus dose with an additional dosage from the pump before each meal to cover the mealtime insulin needs. Option B is incorrect as insulin pumps do not typically release programmed doses of insulin into the bloodstream at specific intervals; instead, they infuse insulin subcutaneously. Option C is incorrect as insulin pumps are not surgically attached to the pancreas; they are worn externally. Option D is incorrect as NPH insulin is not commonly used in insulin pumps, and the pumps do not continuously infuse insulin directly into the bloodstream but rather subcutaneously.
2. The client with type 2 DM is being instructed by the nurse about the importance of controlling blood glucose levels. The nurse should emphasize that uncontrolled blood glucose can lead to:
- A. Increased risk of heart disease and stroke.
- B. Improved wound healing.
- C. Reduced need for medication.
- D. Decreased risk of infection.
Correct answer: A
Rationale: Uncontrolled blood glucose levels are associated with an increased risk of cardiovascular complications, such as heart disease and stroke. High blood glucose levels can damage blood vessels over time, leading to atherosclerosis, which can increase the likelihood of heart disease and stroke. Improved wound healing (choice B) is not a consequence of uncontrolled blood glucose levels; in fact, high blood sugar levels can impair wound healing. Reduced need for medication (choice C) is inaccurate because uncontrolled blood glucose usually necessitates more medication to manage the condition. Decreased risk of infection (choice D) is also misleading as high blood glucose levels can compromise the immune system, making individuals more susceptible to infections.
3. Following a unilateral adrenalectomy, Nurse Betty would assess for hyperkalemia indicated by which of the following signs?
- A. Muscle weakness
- B. Tremors
- C. Diaphoresis
- D. Constipation
Correct answer: A
Rationale: Muscle weakness is a classic manifestation of hyperkalemia, an elevated level of potassium in the blood. After an adrenalectomy, where one adrenal gland is removed, there may be a risk of hyperkalemia due to altered hormone regulation. Tremors (Choice B) are not typically associated with hyperkalemia but may be seen in conditions like hypocalcemia. Diaphoresis (Choice C) and constipation (Choice D) are not specific indicators of hyperkalemia. Diaphoresis is excessive sweating and constipation is a common gastrointestinal issue, neither directly related to potassium imbalances.
4. A client with DM is scheduled to have surgery. The nurse should plan to:
- A. Give the client a regular diet as ordered.
- B. Hold the client's insulin on the morning of surgery.
- C. Monitor the client's blood glucose level closely during the perioperative period.
- D. Have the client stop taking insulin 48 hours before surgery.
Correct answer: C
Rationale: The correct answer is to monitor the client's blood glucose level closely during the perioperative period. This is essential to ensure that the client's blood glucose levels remain within the target range and to prevent complications such as hypo- or hyperglycemia. Choices A, B, and D are incorrect because giving a regular diet as ordered, holding insulin on the morning of surgery, or stopping insulin 48 hours before surgery can lead to uncontrolled blood glucose levels, posing risks to the client's safety during the surgical procedure.
5. A client with hyperthyroidism is prescribed propranolol. The nurse understands that this medication is used to:
- A. Increase metabolism
- B. Reduce anxiety
- C. Decrease heart rate
- D. Increase blood pressure
Correct answer: C
Rationale: Propranolol is a beta-blocker commonly used in the management of hyperthyroidism. It works by blocking the effects of adrenaline, resulting in a decrease in heart rate and blood pressure. Choice A is incorrect because propranolol does not increase metabolism; instead, it may have a mild inhibitory effect. Choice B is incorrect as propranolol is not primarily used to reduce anxiety, although it may have some anxiolytic effects. Choice D is incorrect as propranolol actually decreases blood pressure by blocking the effects of adrenaline on the heart and blood vessels.
