1. 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.

2. Efforts by healthcare facilities to reduce the incidence of hospital-acquired infections (HAIs) include an awareness of which of the following?

• A. The CDC requires all states to report HAI rates from each hospital.
• B. Ensure that the restraints are tied to the side rails.
• C. The gastrointestinal tract is a common site for HAIs.
• D. Joint Commission considers death or serious injury from HAIs a sentinel event.

Correct answer: D

Rationale: Efforts to reduce hospital-acquired infections (HAIs) involve being aware that the Joint Commission considers death or serious injury resulting from HAIs a sentinel event, which must be reported. While more than 20 states require reporting of HAI rates to the CDC, it is not a nationwide CDC requirement. The gastrointestinal tract is not a specific common site for HAIs; rather, bacteria are the primary cause. Ensuring restraints are properly secured is important for patient safety but not directly related to reducing HAIs.

3. The NFPA diamond has four colors. The blue diamond:

• A. indicates hazards to health.
• B. designates that it is safe to use water to put out this type of fire.
• C. indicates that ice is necessary to treat an injury with this type of chemical.
• D. indicates that the chemical may be incinerated upon disposal.

Correct answer: A

Rationale: The National Fire Protection Agency (NFPA) uses a safety diamond to communicate the level of threat posed by a specific chemical. The blue diamond in the NFPA diamond system signifies potential health hazards associated with the use of that chemical. Choice B is incorrect because the blue diamond does not indicate anything about using water to extinguish fires. Choice C is incorrect as the NFPA diamond does not provide information on treating injuries. Choice D is also incorrect as the blue diamond does not suggest incineration upon disposal; it pertains to health hazards.

4. When assessing the pulse of a 6-year-old patient, the nurse notices that the heart rate varies with the respiratory cycle, speeding up at the peak of inspiration and slowing to normal with expiration. What action would the nurse take next?

• A. Notify the physician.
• B. Record this finding as normal.
• C. Check the child's blood pressure and note any variation with respiration.
• D. Document that this child has bradycardia and continue with the assessment.

Correct answer: B

Rationale: The correct action for the nurse to take next is to record this finding as normal. Sinus dysrhythmia, characterized by heart rate variation with the respiratory cycle, is commonly found in children and young adults. The heart rate speeds up at the peak of inspiration and slows to normal with expiration. This phenomenon is a normal variant and does not require any intervention. There is no need to notify the physician as this finding is within the expected range for this age group. Checking the child's blood pressure for variations with respiration or documenting the child as having bradycardia would not be appropriate in this case, as sinus dysrhythmia is a normal physiological response.

5. A nurse is preparing to change a client's dressing for a burn wound on his foot. Which of the following interventions is appropriate for this process?

• A. Wash the wound with cleanser, rinse, and pat dry
• B. Bind the wound tightly, secure with tape, and elevate the foot
• C. Contact the physician after the dressing change is complete
• D. Provide analgesics for the client after the procedure

Correct answer: A

Rationale: When changing the dressing for a burn wound, it is essential to follow appropriate interventions to prevent infection, reduce pain, and support healing. In this scenario, after removing the old dressing, it is crucial to wash the wound gently with a suitable cleanser, rinse the area thoroughly, and then pat it dry. This process helps in maintaining cleanliness, reducing the risk of infection, and providing a conducive environment for healing. Binding the wound tightly (Choice B) can impede circulation and delay healing. Contacting the physician after the dressing change (Choice C) may be necessary in specific situations but is not a standard step in routine dressing changes. Providing analgesics after the procedure (Choice D) is important for pain management but is not directly related to the dressing change itself.
