1. Which of the following joints normally allows 360-degree circumflexion?

A. The knee
B. The shoulder
C. The elbow
D. The fingertips

Correct answer: B

Rationale: The correct answer is B: The shoulder. The shoulder joint is a ball-and-socket joint that allows for a wide range of motion, including 360-degree circumflexion. This joint provides flexibility and mobility in various directions. Choice A, the knee joint, primarily allows flexion and extension but does not have a 360-degree circumflexion. Choice C, the elbow joint, is a hinge joint that permits flexion and extension but not circumflexion. Choice D, the fingertips, do not form a specific joint that allows circumflexion; rather, they have joints that enable bending and straightening movements.

2. What is the softening and thinning of the cervix during labor known as?

A. Dilation
B. Symphysis
C. Effacement
D. Hyperplasia

Correct answer: C

Rationale: Effacement is the correct term for the softening and thinning of the cervix during labor. It is the process where the cervix becomes thinner, allowing it to stretch and open as labor progresses. Choice A, 'Dilation,' is incorrect as it refers to the opening of the cervix. Choice B, 'Symphysis,' is incorrect as it refers to the joint that connects the two pubic bones. Choice D, 'Hyperplasia,' is incorrect as it refers to an increase in the number of cells in an organ or tissue.

3. A nurse is caring for a client who wanders through the halls yelling obscenities at staff, other clients, and visitors. Which of the following actions should the nurse take?

A. Keep the client in their room with the door closed
B. Contact a family member to come and sit with the client
C. Place the client in a wheelchair with a lap tray
D. Administer a sedative to the client

Correct answer: B

Rationale: When dealing with a client exhibiting disruptive behavior like yelling obscenities, involving a family member can provide emotional support and help in de-escalating the situation. Keeping the client isolated in their room (Choice A) may lead to further agitation. Placing the client in a wheelchair (Choice C) or administering a sedative (Choice D) should not be the first interventions for managing behavioral issues.

4. 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.

5. Round off these numbers to the nearest tenth:

A. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
B. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
C. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
D. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7

Correct answer: B

Rationale: The correct answer is B. When rounding off to the nearest tenth, 1.027 becomes 1.0 because the digit in the hundredth's place is less than 5. For the other numbers, they are rounded correctly to the nearest tenth: 5.5778 = 5.6, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7. Therefore, option B is the most accurate in rounding off these numbers to the nearest tenth. Choices A, C, and D are incorrect as they do not round 1.027 to 1.0 as required when rounding to the nearest tenth.
