Nursing Elites

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. Which of the following best defines management?

• A. A manager is someone who ensures that employees complete their work.
• B. A manager controls the work of employees.
• C. A manager organizes and controls a group of employees to get work done.
• D. A manager accomplishes tasks through planning, organizing, commanding, coordinating, and controlling work groups.

Correct answer: D

Rationale: The best definition of management encompasses the comprehensive process of planning, organizing, commanding, coordinating, and controlling work groups to achieve organizational goals. Choice A is too limited, focusing only on ensuring work completion. Choice B is overly restrictive as management involves more than mere control. Choice C is more specific than the correct answer, which encompasses a broader range of managerial functions.

3. A client with type 2 DM is prescribed metformin (Glucophage). The nurse should include which instruction when teaching the client about this medication?

• A. Take the medication with meals.
• B. Take the medication on an empty stomach.
• C. Avoid taking the medication if you miss a meal.
• D. Take the medication before bedtime.

Correct answer: A

Rationale: The correct instruction when taking metformin (Glucophage) is to take the medication with meals. Taking metformin with meals helps to reduce gastrointestinal side effects and improve absorption. Choice B is incorrect because taking metformin on an empty stomach can increase the risk of gastrointestinal side effects. Choice C is incorrect because missing a meal does not mean the medication should be avoided; the client should still take it with the next meal. Choice D is incorrect because there is no specific recommendation to take metformin before bedtime.

4. Jemma, who weighs 210 lb (95 kg) and has been diagnosed with hyperglycemia tells the nurse that her husband sleeps in another room because her snoring keeps him awake. The nurse notices that she has large hands and a hoarse voice. Which of the following would the nurse suspect as a possible cause of the client's hyperglycemia?

• A. Acromegaly
• B. Type 1 diabetes mellitus
• C. Hypothyroidism
• D. Deficient growth hormone

Correct answer: A

Rationale: The correct answer is Acromegaly. Jemma's symptoms of large hands, hoarse voice, and snoring are indicative of acromegaly, a disorder caused by excessive growth hormone production. Acromegaly can lead to insulin resistance, which can result in hyperglycemia. Choice B, Type 1 diabetes mellitus, is unlikely in this case as the symptoms and presentation are more suggestive of acromegaly. Choice C, Hypothyroidism, typically presents with different symptoms such as weight gain, fatigue, and cold intolerance, not consistent with Jemma's symptoms. Choice D, Deficient growth hormone, would not lead to the signs and symptoms observed in Jemma, as her condition is characterized by excessive growth hormone production.

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.
