Nursing Elites

1. What is the most common cause of HHNS?

• A. Insulin overdose
• B. Removal of the adrenal gland
• C. Undiagnosed, untreated hyperpituitarism
• D. Undiagnosed, untreated diabetes mellitus

Correct answer: D

Rationale: The correct answer is D: Undiagnosed, untreated diabetes mellitus. Hyperosmolar hyperglycemic nonketotic syndrome (HHNS) is most commonly caused by undiagnosed and untreated diabetes mellitus. Insulin overdose (Choice A) is not a typical cause of HHNS; it is more related to hypoglycemia. Removal of the adrenal gland (Choice B) can lead to adrenal insufficiency but is not a common cause of HHNS. Undiagnosed, untreated hyperpituitarism (Choice C) is not a usual cause of HHNS; it is more related to pituitary hormone imbalances rather than hyperglycemia.

2. What is the normal sodium level in the body?

• A. 135 to 145 milliequivalents per liter.
• B. 3 to 5 milliequivalents per liter.
• C. 135 to 145 microequivalents per liter.
• D. 3 to 5 microequivalents per liter.

Correct answer: A

Rationale: The correct answer is A: 135 to 145 milliequivalents per liter. The normal range for sodium levels in the body is expressed in milliequivalents per liter, not microequivalents. Choice B and D provide a significantly lower range which is not within the normal values for sodium. Choice C incorrectly states 'microequivalents' instead of the correct unit 'milliequivalents'. Therefore, A is the correct answer.

3. In developing a disaster management plan for a hospital, which resource should be the highest priority to have available in response to a bioterrorism event?

• A. A mental health specialist on the response team
• B. A sufficient supply of PPE
• C. A system for tracking client information
• D. A network for communication between staff members and families

Correct answer: B

Rationale: During a bioterrorism event, the highest priority resource to have available is a sufficient supply of personal protective equipment (PPE). PPE is crucial in protecting healthcare workers and other responders from exposure to biological agents. While mental health support, client information tracking systems, and communication networks are important components of disaster management, in the context of a bioterrorism event, ensuring the safety of staff through adequate PPE takes precedence over other resources.

4. A nurse manager is leading a discussion about ethical dilemmas. Which of the following situations should the nurse manager include as an example of an ethical dilemma?

• A. A visitor experiences a minor burn after spilling coffee
• B. A client receives an operation on the wrong side of her body
• C. A parent wants her 14-year-old adolescent to receive radiation treatment against his will
• D. A nurse witnesses another nurse administer an incorrect medication

Correct answer: C

Rationale: An ethical dilemma involves a situation where moral principles conflict, such as in the case of a parent wanting their adolescent to receive treatment against their will. In option A, a minor burn from spilled coffee does not present a conflict of moral principles. Option B describes a medical error, not necessarily a conflict of moral principles. Option D involves an issue of professional practice and patient safety but does not inherently pose a conflict of moral principles.

5. Select the stage of shock that is accurately paired with its characteristic.

• A. The initial stage of shock: Hyperventilation occurs and the blood pH rises.
• B. The compensatory stage of shock: Hypoxia occurs and lactic acid rises.
• C. The progressive stage of shock: Histamine is released; fluid and proteins leak into surrounding tissues and the blood thickens.
• D. The refractory stage of shock: Potassium ions leak out; sodium ions build up, and metabolic acidosis increases.

Correct answer: C

Rationale: The progressive stage of shock is accurately described as the stage where histamine is released, leading to fluid and proteins leaking into surrounding tissues and the blood thickening. In this stage, the body's compensatory mechanisms are overwhelmed, resulting in a cascade of events that worsen the shock state. Choice A is incorrect as hyperventilation and a rise in blood pH are more characteristic of the compensatory stage. Choice B is incorrect as hypoxia and a rise in lactic acid are more typical of the progressive stage. Choice D is incorrect as the described electrolyte imbalances and metabolic acidosis are more aligned with the refractory stage of shock.
