Nursing Elites

1. What is the approximate duration of action for intermediate-acting insulins like NPH?

• A. 6-8 hours.
• B. 10-14 hours.
• C. 16-20 hours.
• D. 24-28 hours.

Correct answer: C

Rationale: The correct answer is C: '16-20 hours.' Intermediate-acting insulins like NPH typically have a duration of action of approximately 16-20 hours. This prolonged action makes them effective in managing blood glucose levels over an extended period. Choices A, B, and D are incorrect because they do not align with the typical duration of action for intermediate-acting insulins. Choice A (6-8 hours) is too short, choice B (10-14 hours) is also shorter than the typical duration, and choice D (24-28 hours) is too long for intermediate-acting insulins like NPH.

2. 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.

3. A client with DM asks a nurse why it is necessary to rotate injection sites when using an insulin pen. The nurse's best response would be:

• A. To prevent scar tissue from forming under the skin.
• B. To make the injections less painful.
• C. To help the insulin absorb better.
• D. To keep the skin looking healthy.

Correct answer: C

Rationale: The correct answer is C: "To help the insulin absorb better." Rotating injection sites is important as it helps to ensure better insulin absorption and reduces the risk of developing lipodystrophy. Option A is incorrect as rotating sites primarily aims to optimize insulin absorption, not prevent scar tissue. Option B is inaccurate because rotating injection sites does not necessarily make the injections less painful. Option D is incorrect as the primary reason for rotating injection sites is not related to the aesthetics of the skin but rather to enhance insulin absorption and prevent complications.

4. Which of the following ethical principles is demonstrated when a nurse provides truthful information to a patient?

• A. Veracity
• B. Autonomy
• C. Justice
• D. Nonmaleficence

Correct answer: A

Rationale: The correct answer is A: Veracity. Veracity is the ethical principle of truthfulness and honesty in communication. When a nurse provides truthful information to a patient, it demonstrates integrity and respect for the patient's right to know the truth about their health condition and treatment. Choice B, Autonomy, refers to respecting the patient's right to make their own decisions. Choice C, Justice, involves fairness and equality in healthcare decisions. Choice D, Nonmaleficence, relates to the obligation to do no harm and prevent harm to the patient.

5. A healthcare professional is reading a physician's progress notes in the client's record and reads that the physician has documented 'insensible fluid loss of approximately 800 mL daily.' The healthcare professional understands that this type of fluid loss can occur through:

• A. The skin
• B. Urinary output
• C. Wound drainage
• D. The gastrointestinal tract

Correct answer: A

Rationale: Insensible fluid loss refers to the fluid lost from the body that is not easily measured, such as through sweating and respiration. The skin is a major contributor to insensible fluid loss due to evaporation of water through the skin. Choice B, urinary output, represents measurable fluid loss through urine excretion. Choice C, wound drainage, is a measurable form of fluid loss that occurs externally from a wound. Choice D, the gastrointestinal tract, primarily involves fluid loss through feces and is also a measurable form of output. Therefore, the correct answer is 'A: The skin,' as it is the main route for insensible fluid loss.
