Nokea
For a diabetic male client with a foot ulcer, the physician orders bed rest, a wet-to-dry dressing change every shift, and blood glucose monitoring before meals and bedtime. Why are wet-to-dry dressings used for this client?
- A. They contain exudate and provide a moist wound environment.
- B. They protect the wound from mechanical trauma and promote healing.
- C. They debride the wound and promote healing by secondary intention.
- D. They prevent the entrance of microorganisms and minimize wound discomfort.
Correct Answer: C
Rationale: Wet-to-dry dressings are utilized in this case to debride the wound by removing dead tissue and promoting healing by secondary intention. Choice A is incorrect as wet-to-dry dressings do not provide a moist wound environment; instead, they promote drying to aid in debridement. Choice B is incorrect because their primary purpose is not to protect the wound but to remove dead tissue. Choice D is incorrect as the main function of wet-to-dry dressings is not to prevent the entrance of microorganisms or minimize wound discomfort.

A client with DM is scheduled for surgery. The nurse should plan to:
- A. Monitor the client's blood glucose level closely during the perioperative period.
- B. Give the client a regular diet as ordered.
- C. Have the client stop taking insulin 48 hours before surgery.
- D. Hold the client's insulin on the morning of surgery.
Correct Answer: A
Rationale: The correct answer is to monitor the client's blood glucose level closely during the perioperative period. For a client with diabetes mellitus (DM) scheduled for surgery, it is essential to closely monitor blood glucose levels to prevent hypo- or hyperglycemia. Choice B is incorrect because giving the client a regular diet as ordered may not address the specific needs related to managing blood glucose levels in the perioperative period. Choice C is incorrect as abruptly stopping insulin 48 hours before surgery can lead to uncontrolled blood sugar levels, which is not recommended. Choice D is incorrect because holding the client's insulin on the morning of surgery can also disrupt blood sugar control, potentially leading to complications during the perioperative period.
A client with DM visits the health care clinic. The client's diabetes has been well controlled with glyburide (Diabeta), 5 mg PO daily, but recently the fasting blood glucose has been running 180-200 mg/dl. Which medication, if added to the client's regimen, may have contributed to the hyperglycemia?
- A. Atenolol (Tenormin)
- B. Prednisone (Deltasone)
- C. Phenelzine (Nardil)
- D. Allopurinol (Zyloprim)
Correct Answer: B
Rationale: The correct answer is B. Prednisone is a corticosteroid that can cause hyperglycemia by increasing glucose production in the liver. Atenolol (Choice A) is a beta-blocker that typically does not affect blood glucose levels significantly. Phenelzine (Choice C) is a monoamine oxidase inhibitor used for depression and does not directly impact blood glucose levels. Allopurinol (Choice D) is a xanthine oxidase inhibitor used to manage gout and does not contribute to hyperglycemia.
A client with type 1 diabetes mellitus is experiencing hypoglycemia. What should the nurse instruct the client to do?
- A. Administer insulin immediately
- B. Consume 15 grams of simple carbohydrates
- C. Drink plenty of water
- D. Avoid eating until symptoms resolve
Correct Answer: B
Rationale: When a client with type 1 diabetes mellitus experiences hypoglycemia, the nurse should instruct them to consume 15 grams of simple carbohydrates. This is the recommended initial treatment for hypoglycemia as it helps quickly raise blood sugar levels to alleviate symptoms and prevent complications. Administering insulin immediately (Choice A) would further lower blood sugar levels, worsening the hypoglycemia. Drinking plenty of water (Choice C) and avoiding eating until symptoms resolve (Choice D) are not appropriate actions for treating hypoglycemia as they do not address the immediate need to raise blood sugar levels.
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.
The nurse is caring for a client with syndrome of inappropriate antidiuretic hormone (SIADH). Which of the following clinical findings should the nurse expect?
- A. Hyponatremia
- B. Hyperkalemia
- C. Hypercalcemia
- D. Hypernatremia
Correct Answer: A
Rationale: In SIADH, there is excessive release of antidiuretic hormone (ADH), leading to water retention and dilutional hyponatremia. Hyponatremia is a hallmark finding in SIADH due to the imbalance between water and sodium levels. Hyperkalemia (Choice B) is not typically associated with SIADH. Hypercalcemia (Choice C) involves elevated calcium levels, which are not directly related to SIADH. Hypernatremia (Choice D) is the opposite of what occurs in SIADH, where sodium levels are usually diluted due to water retention.
