1. An advance directive known as a durable power of attorney involves appointing another person called a(n) _____ to act as the decision maker in the event of the patient's incapacitation.
- A. witness
- B. primary caregiver
- C. health care agent
- D. state proxy
Correct answer: C
Rationale: The correct answer is 'health care agent.' A health care agent is appointed through a durable power of attorney to make medical decisions on behalf of a patient who becomes incapacitated. The term 'witness' (choice A) is incorrect because a witness only observes the signing of the directive and does not make decisions. 'Primary caregiver' (choice B) is also incorrect as they may provide care but are not necessarily legally empowered to make decisions. 'State proxy' (choice D) is not commonly used in the context of advance directives or health care decision making, making it an incorrect choice.
2. Water loss can occur from each, except one. Which is the exception?
- A. Respiratory inflammation
- B. Strenuous exercise
- C. Diarrhea
- D. Perspiration
Correct answer: D
Rationale: The correct answer is D, Perspiration. Water loss can occur through respiration inflammation, strenuous exercise, and diarrhea. Perspiration, also known as sweating, is a mechanism by which the body regulates temperature and eliminates some waste products, but it is not a cause of water loss. The body loses water through sweating, but this loss is mainly for cooling purposes, and it is not a primary mechanism for water loss like respiration, exercise, or diarrhea.
3. How is the stomach protected from damage by gastric acid?
- A. enzymes present in the stomach
- B. a protective bacteria in the stomach
- C. bicarbonate present in the stomach
- D. the mucus lining of the stomach
Correct answer: D
Rationale: The correct answer is D. The stomach is protected from gastric acid by a thick mucus lining that acts as a physical barrier, preventing the acid from eroding the stomach walls. Enzymes in the stomach help with digestion but do not play a significant role in protecting the stomach from acid damage, so choice A is incorrect. While some bacteria in the stomach can be beneficial, they do not primarily protect the stomach from gastric acid, making choice B incorrect. Bicarbonate, a base, can neutralize acid, but it is not the primary defense mechanism against gastric acid in the stomach, so choice C is also incorrect.
4. While on Bryant’s traction, which of these observations of Graciela and her traction apparatus would indicate a decrease in the effectiveness of her traction?
- A. Graciela’s buttocks are resting on the bed.
- B. The traction weights are hanging 10 inches above the floor.
- C. Graciela’s legs are suspended at a 90 degree angle to her trunk.
- D. The traction ropes move freely through the pulley.
Correct answer: D
Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
5. Which of the following is the least likely reason that osteoporosis is more prevalent in women?
- A. women have smaller bodies
- B. women have lower bone mass
- C. women consume less calcium
- D. bone loss begins later in women
Correct answer: D
Rationale: The correct answer is D. Contrary to the statement, bone loss begins earlier in women, particularly after menopause, due to the decrease in estrogen levels. This drop in estrogen accelerates bone loss, contributing to the higher prevalence of osteoporosis in women. Choices A, B, and C are more likely reasons for the increased prevalence of osteoporosis in women. Women generally have smaller bodies, lower bone mass compared to men, and may consume less calcium, all of which are significant factors contributing to the higher incidence of osteoporosis in women.
