1. Dina, 17 years old, asks you how a tubal ligation prevents pregnancy. Which would be the best answer?

A. Prostaglandins released from the cut fallopian tubes can kill sperm
B. Sperm cannot enter the uterus because the cervical entrance is blocked
C. Sperm can no longer reach the ova, because the fallopian tubes are blocked
D. The ovary no longer releases ova as there is nowhere for them to go

Correct answer: C

Rationale: The correct answer is C: 'Sperm can no longer reach the ova because the fallopian tubes are blocked.' Tubal ligation works by blocking the fallopian tubes, preventing sperm from reaching the egg for fertilization. Choice A is incorrect because prostaglandins are not released from the cut fallopian tubes to kill sperm. Choice B is incorrect as the cervical entrance being blocked does not relate to tubal ligation. Choice D is incorrect because tubal ligation does not affect the release of ova from the ovary.

2. Characteristics of type two diabetes include all of the following except:

A. insulin resistance
B. blood glucose levels that rise too high
C. blood insulin levels that rise too high
D. rapid destruction of the pancreas

Correct answer: D

Rationale: Type 2 diabetes is characterized by insulin resistance, high blood glucose levels, and high blood insulin levels. Rapid destruction of the pancreas is not a feature of this condition. The destruction of pancreatic beta cells is more commonly associated with type 1 diabetes, not type 2 diabetes. Therefore, option D is the correct answer. Options A, B, and C are all characteristic features of type 2 diabetes, making them incorrect choices.

3. A nurse is teaching a client who needs to increase their daily fluid intake. Which of the following foods has the highest percentage of water by weight?

A. Yogurt
B. Milk
C. Lettuce
D. Honey

Correct answer: C

Rationale: The correct answer is Lettuce. Lettuce has the highest percentage of water by weight among the options provided, making it an excellent choice to increase fluid intake. Yogurt and milk have some water content but are not as high in water percentage as lettuce. Honey, on the other hand, contains very little water and is not a good choice for increasing fluid intake.

4. Which is NOT a characteristic or function of lipids?

A. Involved in energy metabolism and storage
B. Provide insulation and protection
C. Act as hormones that regulate the body
D. Are hydrophilic

Correct answer: D

Rationale: Lipids are known for several functions including involvement in energy metabolism and storage (Choice A), providing insulation and protection (Choice B), and acting as hormones that regulate the body (Choice C). However, lipids are not hydrophilic (water-attracting), contrary to choice D. They are actually hydrophobic, meaning they repel water and do not mix well with it. This is a key property that differentiates them from many other biological molecules.

5. The only IV fluid compatible with blood products is:

A. D5LR C. NSS
B. D5NSS D. Plain LR
C.
D.

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.
