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.

Which of the following is a nursing issue of concern today?
- A. Safe staffing
- B. Low workloads
- C. Increasing professional autonomy
- D. Improving salaries
Correct Answer: A
Rationale: The correct answer is A: Safe staffing. Safe staffing is a critical issue in nursing today due to its impact on patient outcomes and nurse well-being. While low workloads (choice B) may seem beneficial, they can also indicate understaffing, leading to burnout and compromising patient care. Increasing professional autonomy (choice C) is generally viewed positively as it empowers nurses, and improving salaries (choice D) is important but may not directly address patient safety concerns related to staffing levels.
Which of the following best describes cultural competence in healthcare?
- A. Ignoring cultural differences
- B. Understanding and respecting cultural differences
- C. Enforcing cultural norms
- D. Focusing solely on medical knowledge
Correct Answer: B
Rationale: Cultural competence in healthcare involves understanding and respecting cultural differences to provide effective and respectful care to patients from diverse backgrounds. Choice A is incorrect as ignoring cultural differences goes against the principles of cultural competence. Choice C is wrong because enforcing cultural norms can be culturally insensitive and may not align with the patient's beliefs. Choice D is also incorrect as cultural competence encompasses more than just medical knowledge, including communication, empathy, and awareness of cultural factors.
What does the mnemonic device ABCDE stand for?
- A. Allergy, bleeding, chemicals, dietary, environment
- B. Allergy, bleeding, cardio, diabetes, endocrine
- C. Allergy, bleeding, cardio, digestive, endocrine
- D. Allergy, bleeding, cortisone, diabetes, emboli
Correct Answer: D
Rationale: The correct answer is D: 'Allergy, bleeding, cortisone, diabetes, emboli.' The ABCDE mnemonic is used in healthcare to help remember key assessment points. Choice A is incorrect as 'chemicals' and 'dietary' are not part of the ABCDE assessment. Choice B is incorrect as 'cardio' is not part of the ABCDE mnemonic. Choice C is incorrect as 'cardio' and 'digestive' are not part of the ABCDE mnemonic.
Nurse Andy has finished teaching a client with diabetes mellitus how to administer insulin. He evaluates the learning has occurred when the client makes which statement?
- A. I should check my blood sugar immediately prior to the administration.
- B. I should provide direct pressure over the site following the injection.
- C. I should use the abdominal area only for insulin injections.
- D. I should only use a calibrated insulin syringe for the injections.
Correct Answer: D
Rationale: The correct answer is D because using a calibrated insulin syringe is crucial for accurate dosing when administering insulin. Choice A is incorrect because checking blood sugar before administration is essential but not the specific evaluation of learning in this context. Choice B is incorrect as applying direct pressure over the injection site is not a key indicator of learning about insulin administration. Choice C is incorrect as insulin injections can also be administered in other sites like the thigh or arm; it is not limited to the abdominal area.
Which of the following is considered normal for the neonate?
- A. Chest Circumference: 10 to 13 inches
- B. Length: 16 to 22 inches
- C. Weight: 1,500 to 4,000 g
- D. Head Circumference: 12.6 to 14.5 inches
Correct Answer: D
Rationale: A normal head circumference for a neonate typically falls within the range of 12.6 to 14.5 inches. Choice A is incorrect because the chest circumference for a neonate is usually smaller. Choice B is incorrect as the length of a neonate is typically shorter. Choice C is incorrect as the weight of a neonate is usually measured in grams and falls within a different range.
