A nurse is preparing to administer NPH insulin to a client with DM. The nurse notes that the NPH insulin vial is cloudy. The nurse should:
- A. Obtain a new vial of NPH insulin.
- B. Draw up the cloudy insulin as ordered.
- C. Shake the vial vigorously before drawing up the insulin.
- D. Warm the insulin to room temperature before administration.
Correct Answer: B
Rationale: The correct answer is to draw up the cloudy insulin as ordered. NPH insulin is inherently cloudy due to its suspension of insulin crystals. Shaking the vial vigorously can lead to denaturation of the insulin molecules, altering its efficacy. Warming NPH insulin is not necessary as it can cause breakdown of insulin molecules. The nurse should gently roll the vial between hands to mix it before drawing it up to ensure an even distribution of insulin in the suspension.

Which of the following describes an effective method of communication?
- A. A unit manager meets with a new nurse to discuss what is going well and areas for improvement.
- B. A unit manager meets with a new nurse to explain departmental policies.
- C. A unit manager meets with staff after several safety events to introduce new policies aimed at preventing further safety events.
- D. A unit manager describes safety events that have occurred on the unit to another nurse manager and discusses ideas for policy improvement with the other manager.
Correct Answer: A
Rationale: Choice A is the correct answer because it describes an effective method of communication where a unit manager meets with a new nurse to discuss what is going well and areas for improvement. This approach fosters open dialogue, provides constructive feedback, and promotes professional growth. Choice B is incorrect as it only involves the explanation of departmental policies without engaging in a two-way communication process. Choice C is incorrect as it focuses on policy introduction after safety events rather than individual feedback. Choice D is incorrect as it involves discussing safety events with another manager and policy improvement, but it does not directly address individual performance feedback, which is essential for effective communication and professional development.
For a male client with hyperglycemia, which assessment finding best supports a nursing diagnosis of Deficient fluid volume?
- A. Cool, clammy skin
- B. Distended neck veins
- C. Increased urine osmolarity
- D. Decreased serum sodium level
Correct Answer: C
Rationale: Increased urine osmolarity is the best assessment finding supporting a nursing diagnosis of Deficient fluid volume in a male client with hyperglycemia. In hyperglycemia, there is increased glucose in the blood, which leads to osmotic diuresis. This results in the excretion of large amounts of urine that is concentrated (high osmolarity), leading to dehydration and fluid volume deficit. Cool, clammy skin (Choice A) is more indicative of poor perfusion, distended neck veins (Choice B) are associated with fluid volume excess, and decreased serum sodium level (Choice D) could be a result of dilutional hyponatremia due to fluid overload rather than deficient fluid volume.
A client with hyperthyroidism is being treated with radioactive iodine. The nurse should teach the client to expect which of the following side effects?
- A. Increased heart rate
- B. Hypothyroidism
- C. Hypercalcemia
- D. Weight loss
Correct Answer: B
Rationale: When a client with hyperthyroidism undergoes radioactive iodine treatment, it often leads to hypothyroidism due to the destruction of thyroid tissue. This occurs as a desired outcome of the treatment to reduce the overactive thyroid function. Choices A, C, and D are incorrect. Increased heart rate, hypercalcemia, and weight loss are not expected side effects of radioactive iodine treatment for hyperthyroidism. Instead, the goal is to suppress the overactive thyroid, leading to a hypothyroid state.
A client with Addison's disease is receiving corticosteroid therapy. The nurse should monitor the client for which of the following potential side effects?
- A. Hypoglycemia
- B. Hypertension
- C. Weight loss
- D. Hyperkalemia
Correct Answer: B
Rationale: When a client with Addison's disease is receiving corticosteroid therapy, the nurse should monitor for hypertension as a potential side effect. Corticosteroids can lead to hypertension by causing fluid retention and increased blood volume. Hypoglycemia (Choice A) is not a common side effect of corticosteroid therapy; instead, hyperglycemia is more likely. Weight loss (Choice C) is not a typical side effect of corticosteroid therapy; in fact, weight gain is more common due to fluid retention and increased appetite. Hyperkalemia (Choice D) is a potential side effect of Addison's disease itself due to adrenal insufficiency, but it is not directly caused by corticosteroid therapy.
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.
