1. Which of the following is a disadvantage of using a dry heat application?

A. Dry heat is more likely to cause burns than moist heat
B. Dry heat does not penetrate deeply into the tissues
C. Dry heat causes the skin to dry out more quickly
D. Dry heat can quickly cause skin breakdown

Correct answer: C

Rationale: The correct answer is that dry heat causes the skin to dry out more quickly. When comparing dry and moist heat applications, dry heat is less likely to cause burns and skin breakdown. However, one of the disadvantages of dry heat is that it does not penetrate deeply into the tissues and may lead to faster drying out of the skin. This can have negative effects on skin integrity and overall comfort during therapy. Choice A is incorrect because dry heat is less likely to cause burns than moist heat. Choice B is incorrect as dry heat may not penetrate deeply into tissues. Choice D is incorrect as dry heat is less likely to cause skin breakdown compared to moist heat.

2. While measuring a patient's blood pressure, which factor influences a patient's blood pressure?

A. Pulse rate
B. Pulse pressure
C. Vascular output
D. Peripheral vascular resistance

Correct answer: D

Rationale: When measuring a patient's blood pressure, it is important to consider various factors that influence blood pressure. Peripheral vascular resistance plays a crucial role in regulating blood pressure. The level of blood pressure is affected by factors such as cardiac output, peripheral vascular resistance, volume of circulating blood, viscosity, and elasticity of the vessel walls. Pulse rate (Choice A) refers to the number of heartbeats per minute and is not a primary factor influencing blood pressure. Pulse pressure (Choice B) is the difference between systolic and diastolic blood pressure and does not directly impact blood pressure regulation. Vascular output (Choice C) is not a recognized term in blood pressure regulation and is not a primary factor affecting blood pressure.

3. Who is the center of care?

A. The doctor
B. The administrator
C. The patient
D. The nurse

Correct answer: C

Rationale: The PATIENT is the center of care and the core of the healthcare team. The PATIENT holds the utmost importance within the healthcare setting. Healthcare professionals collaborate as a team to effectively address the needs of the patient. The primary focus should always be on the patient, who plays a crucial role in decision-making. While other healthcare team members, such as doctors, nurses, and administrators, play vital roles, the patient remains the central figure. The patient has the fundamental right to receive quality care from all members of the healthcare team.

4. All of the following factors may contribute to client falls EXCEPT:

A. Contact dermatitis
B. Urinary frequency
C. Decreased visual acuity
D. Confusion

Correct answer: A

Rationale: Client falls can result from various factors, both intrinsic and extrinsic. Intrinsic factors include health conditions like urinary frequency, which increases the need for bathroom visits, decreased visual acuity, and confusion. These factors can directly contribute to an increased risk of falls. However, contact dermatitis does not directly lead to falls. Contact dermatitis is a skin condition caused by contact with irritants or allergens and does not inherently predispose individuals to falling. Therefore, among the given options, contact dermatitis is the only factor that is not directly associated with an increased risk of falls.

5. A client has become combative and is attempting to pull out his IV and take off his surgical dressings. The nurse receives an order to apply wrist restraints. Which action of the nurse signifies that restraints are being used safely?

A. The nurse ties the restraints in a square knot to prevent the client from untying them
B. The restraints are attached to a movable portion of the bed
C. The padded side of the restraint is applied next to the skin of the wrist
D. The nurse assesses the client's distal circulation every 24 hours

Correct answer: C

Rationale: Restraint use must prioritize the safety of the client. When applying restraints around the wrists, the padded side should be placed against the skin to help prevent skin breakdown. Additionally, restraints should be secured in quick-release knots to ensure they can be removed rapidly in case of an emergency. Choice A is incorrect as restraints should not be tied in a way that could prevent quick removal. Choice B is incorrect because restraints should not be attached to a movable part of the bed to avoid unintentional movement. Choice D is incorrect as assessing distal circulation is important but is not directly related to the safe application of restraints.
