Nursing Elites

1. 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.

2. When a woman has miscarried in three or more consecutive pregnancies, it is referred to as which type of spontaneous abortion?

• A. Inevitable
• B. Missed
• C. Habitual
• D. Threatened

Correct answer: C

Rationale: The correct answer is C, 'Habitual.' Habitual abortion is defined as three or more consecutive miscarriages, making it the appropriate term for this situation. Choice A, 'Inevitable,' refers to a miscarriage that cannot be prevented. Choice B, 'Missed,' refers to a miscarriage where the fetus has died but has not been expelled. Choice D, 'Threatened,' refers to a situation where there is bleeding in early pregnancy but the cervix remains closed.

3. A client with a tumor refuses surgery, but the client's partner wants it. Which is the deciding factor in determining if the surgery will be done?

• A. Whether the partner is the client's durable power of attorney for healthcare
• B. Whether the client understands the risk of refusing the procedure
• C. Whether the client's refusal is based on religious belief
• D. Whether the facility's ethical committee reaches a consensus on the case

Correct answer: B

Rationale: The correct answer is B because the client's understanding of the risks involved in refusing the surgery is crucial in determining the course of action. In this scenario, the client's autonomy and decision-making capacity take precedence. Choice A is not directly relevant to the decision-making process regarding surgery. Choice C, religious beliefs, may influence the decision but should not be the determining factor in this case. Choice D involving the facility's ethical committee is not typically involved in individual patient care decisions.

4. 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.

5. A nurse is assessing a client with a suspected diagnosis of hypocalcemia. Which of the following clinical manifestations would the nurse expect to note in the client?

• A. Twitching
• B. Positive Trousseau's sign
• C. Hyperactive bowel sounds
• D. Hyperactive deep tendon reflexes

Correct answer: A

Rationale: The correct answer is A: Twitching. Hypocalcemia often presents with neuromuscular irritability, leading to manifestations such as twitching. Trousseau's sign is actually a positive indicator of hypocalcemia, not negative, making choice B incorrect. Hypoactive bowel sounds are not typically associated with hypocalcemia, making choice C incorrect. Similarly, hypoactive deep tendon reflexes are not a common finding in hypocalcemia, making choice D incorrect.
