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. What is a cavity containing pus surrounded by inflamed tissue?

• A. Cellulitis.
• B. An abscess.
• C. Extravasation.
• D. An adhesion.

Correct answer: B

Rationale: An abscess is defined as a cavity containing pus surrounded by inflamed tissue. Cellulitis is a bacterial skin infection causing redness and swelling, not a cavity. Extravasation is the leakage of fluid from a vessel into surrounding tissues, not a cavity. An adhesion is a band of scar-like tissue that binds two parts together, not a cavity containing pus and inflamed tissue.

3. What is the expected date of delivery for a woman whose last menstrual period was on April 20th?

• A. January 20th
• B. January 27th
• C. January 29th
• D. January 31st

Correct answer: B

Rationale: The expected date of delivery is calculated by adding 9 months and 7 days to the last menstrual period. For April 20th, the expected date is January 27th. Therefore, the correct answer is B. Choice A, January 20th, is incorrect as it does not account for the additional 7 days. Choice C, January 29th, and Choice D, January 31st, are also incorrect as they do not consider the standard calculation method for estimating the due date.

4. Which of the following is the best way for a nurse to improve quality of care?

• A. Recognize that physicians are among the health-care professionals interested in improving quality of care.
• B. Work with patients and families to improve healthcare.
• C. Collaborate with other health-care professionals, patients, and their families.
• D. Recognize that physicians are among the numerous professionals in health care.

Correct answer: C

Rationale: The best way for a nurse to improve the quality of care is by collaborating with other health-care professionals, patients, and their families. By working together with the healthcare team, patients, and families, nurses can ensure a holistic approach to care delivery, leading to better outcomes. Choices A and D are incorrect as they focus solely on physicians, while choice B, though important, does not fully encompass the collaborative aspect necessary for comprehensive care.

5. Most water leaves the body by way of the:

• A. Lungs
• B. Intestines
• C. Skin
• D. Kidneys

Correct answer: D

Rationale: Most water leaves the body through the kidneys. The kidneys play a crucial role in filtering waste and excess substances from the blood to form urine, which is then excreted out of the body. Choices A, B, and C are incorrect because while a small amount of water can be lost through respiration, feces, and sweating, the primary organ responsible for regulating water balance and excretion is the kidneys.
