1. When auscultating the blood pressure of a 25-year-old patient, the nurse notices that the phase I Korotkoff sounds begin at 200 mm Hg. At 100 mm Hg, the Korotkoff sounds muffle. At 92 mm Hg, the Korotkoff sounds disappear. How should the nurse record this patient's blood pressure?

A. 200/92
B. 200/100
C. 100/200/92
D. 200/100/92

Correct answer: A

Rationale: When auscultating blood pressure, it is crucial to note the points at which Korotkoff sounds change. In adults, the last audible sound indicates the diastolic pressure. In this case, the Korotkoff sounds muffle at 100 mm Hg and disappear at 92 mm Hg. Therefore, the blood pressure should be recorded as systolic/diastolic, which is 200/92. Choices B, C, and D are incorrect because they do not reflect the correct points where the Korotkoff sounds change during blood pressure measurement.

2. 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.

3. In a 68-year-old man, a gradual loss of hearing is known as _____________.

A. presbycusis
B. xerostomia
C. myopia
D. presbyopia

Correct answer: A

Rationale: The correct answer is 'presbycusis.' Presbycusis is the age-related gradual loss of hearing ability, commonly seen in the elderly population. Xerostomia refers to dry mouth, myopia is nearsightedness, and presbyopia is the age-related loss of the eye's ability to focus on close objects. Given Mr. Roberts' age and symptom of gradual hearing loss, presbycusis is the most likely diagnosis. Xerostomia, myopia, and presbyopia do not match the sensory change described in the question, making them incorrect choices.

4. When dismissing a 5-year-old boy from the pediatrics unit, what type of seat belt restraint should the child wear as the parents drive the car to the front door of the hospital?

A. A 5-point restraint in the back seat, facing backward
B. A booster seat with a lap and shoulder belt in the back seat
C. A lap belt in the back seat
D. A lap and shoulder belt in the front seat

Correct answer: B

Rationale: A 5-year-old child riding in a car should use a restraint system for safety. The Centers for Disease Control and Prevention recommend that children under 13 years should not ride in the front seat of a car due to safety concerns. For a 5-year-old child, a booster seat with a lap and shoulder belt in the back seat is the most appropriate choice. This setup ensures proper protection and restraint for the child's size and age. Choice A is incorrect because a 5-point restraint system facing backward is not suitable for a 5-year-old child in a car. Choice C is incorrect as a lap belt alone does not provide adequate protection for a child of this age. Choice D is incorrect as children should not be seated in the front seat, especially at this young age.

5. Which is the most effective action for controlling the spread of infection?

A. Thorough hand hygiene
B. Wearing gloves and masks when providing direct client care
C. Implementing appropriate isolation precautions
D. Administering broad-spectrum prophylactic antibiotics

Correct answer: A

Rationale: Thorough hand hygiene is the most effective action for controlling the spread of infection as hands are a common source of transmission. Regular and routine hand hygiene helps prevent the movement of potentially infective materials. Wearing gloves and masks is important when providing direct client care to protect both the caregiver and the patient, but it is not as effective as thorough hand hygiene in preventing overall infection spread. Implementing appropriate isolation precautions is necessary for clients with known communicable diseases, but it is not as universally effective in preventing the spread of various infections. Administering broad-spectrum prophylactic antibiotics is not an appropriate measure for controlling the spread of infection as routine use can lead to superinfection and the development of resistant organisms.
