1. A male client with a tentative diagnosis of hyperosmolar hyperglycemic nonketotic syndrome (HHNS) has a history of type 2 diabetes that is being controlled with an oral diabetic agent, tolazamide (Tolinase). Which of the following is the most important laboratory test for confirming this disorder?

• A. Serum potassium level
• B. Serum sodium level
• C. Arterial blood gas (ABG) values
• D. Serum osmolarity

Correct answer: D

Rationale: Serum osmolarity is the most important laboratory test for confirming hyperosmolar hyperglycemic nonketotic syndrome (HHNS). HHNS is characterized by severe hyperglycemia and dehydration without ketoacidosis. Elevated serum osmolarity indicates increased solute concentration in the blood, which is a hallmark of HHNS. Serum potassium level (Choice A) is important in conditions like diabetic ketoacidosis rather than HHNS. Serum sodium level (Choice B) may be affected in HHNS but is not the primary test for confirming the disorder. Arterial blood gas (ABG) values (Choice C) are more useful in assessing acid-base status, which is not the primary concern in HHNS.

2. The healthcare provider is assessing a client with hypothyroidism. Which of the following symptoms would the provider expect to find?

• A. Weight loss
• B. Heat intolerance
• C. Bradycardia
• D. Diarrhea

Correct answer: C

Rationale: Bradycardia is a common symptom of hypothyroidism because the condition leads to a decreased metabolic rate. Weight loss (Choice A) is more commonly associated with hyperthyroidism, where the metabolic rate is increased. Heat intolerance (Choice B) is also more indicative of hyperthyroidism due to increased sensitivity to heat. Diarrhea (Choice D) is not a typical symptom of hypothyroidism; rather, constipation is more common due to the slow-down of the digestive system.

3. The client with type 2 DM is being taught about the importance of foot care. Which instruction should be included?

• A. Soak your feet in hot water every night.
• B. Walk barefoot whenever possible.
• C. Use a heating pad to warm your feet.
• D. Wear comfortable shoes that allow air circulation.

Correct answer: D

Rationale: The correct instruction for the client with type 2 DM regarding foot care is to wear comfortable shoes that allow air circulation. This helps prevent foot injuries and infections, which are common complications in clients with diabetes. Choice A is incorrect as soaking feet in hot water can lead to burns and skin damage. Choice B is incorrect because walking barefoot increases the risk of injury and infection. Choice C is incorrect as using a heating pad can also potentially lead to burns and skin damage.

4. The client with DM is being taught about foot care. The nurse instructs the client to:

• A. Avoid hot water when bathing the feet.
• B. Apply a moisturizing lotion to the feet, especially between the toes.
• C. Use a heating pad to warm the feet if they feel cold.
• D. Go barefoot at home to allow the feet to air out.

Correct answer: A

Rationale: The correct answer is to avoid hot water when bathing the feet. This instruction is crucial because clients with diabetes may have decreased sensation in their feet, which can put them at risk of burns from hot water. Choice B is incorrect because applying moisturizing lotion between the toes can increase moisture and promote fungal growth. Choice C is incorrect because using a heating pad can also lead to burns due to decreased sensation. Choice D is incorrect as going barefoot can increase the risk of injury and infections in clients with diabetes.

5. Why is glucose an important molecule in a cell?

• A. Extraction of energy
• B. Synthesis of protein
• C. Building of genetic material
• D. Formation of cell membranes

Correct answer: A

Rationale: Glucose is a crucial molecule in cells because it serves as the primary source of energy through cellular respiration. Choice B, the synthesis of protein, is incorrect because proteins are typically synthesized from amino acids, not glucose. Choice C, the building of genetic material, is incorrect because genetic material, such as DNA and RNA, is not directly built from glucose. Choice D, the formation of cell membranes, is also incorrect as cell membranes are primarily composed of lipids and proteins, not glucose.
