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. According to the American Heart Association standards, high-quality CPR for an adult includes all of the following EXCEPT:

• A. Push hard
• B. Push fast
• C. Allow chest recoil between compressions
• D. Pause CPR as each drug is administered

Correct answer: D

Rationale: High-quality CPR for adults should not be paused for drug administration. The correct CPR technique involves pushing hard and fast, at a rate of at least 100 compressions per minute and to a depth of at least 2 inches. It is also essential to allow chest recoil between compressions to enable proper blood circulation. Pausing CPR for drug administration would delay the delivery of continuous chest compressions, which are crucial for maintaining blood flow and oxygenation during cardiac arrest.

3. Which of these guidelines would a healthcare professional follow when measuring a patient's weight?

• A. The patient is always weighed wearing only undergarments.
• B. The type of scale matters and should be consistent day to day.
• C. The patient should remove heavy outer clothing, shoes, and jackets before weighing.
• D. Attempts should be made to weigh the patient at approximately the same time of day if a sequence of weights is necessary.

Correct answer: D

Rationale: When measuring a patient's weight, it is important to ensure accuracy and consistency. If a sequence of repeated weights is necessary, the healthcare professional should attempt to weigh the patient at the same time of day and with the same types of clothing worn each time. It is crucial to use a standardized balance or electronic standing scale for accurate weight measurement. Choice A is incorrect as patients should remove heavy outer clothing, shoes, and jackets before being weighed for accurate results. Choice B is incorrect because the type of scale used does matter and should be consistent for reliable weight tracking. Choice C is incorrect as patients should not leave on heavy outer clothing, shoes, or jackets as these items can add to the weight recorded inaccurately.

4. The student observes a patient with no breathing problems. Which action by the student indicates a need to review respiratory assessment skills?

• A. The student starts at the apices of the lungs and moves to the bases.
• B. The student compares breath sounds from side to side, avoiding bony areas.
• C. The student places the stethoscope over the posterior chest and listens during expiration.
• D. The student instructs the patient to breathe slowly and a little more deeply than normal through the mouth.

Correct answer: C

Rationale: The correct answer is C. Listening only during inspiration instead of both inspiration and expiration indicates a need for a review of respiratory assessment skills. During chest auscultation, it is essential to listen to at least one cycle of inspiration and expiration at each placement of the stethoscope. Instructing the patient to breathe slowly and a little deeper than normal through the mouth is a correct practice during auscultation. The correct sequence for lung auscultation is from the apices to the bases, comparing breath sounds bilaterally, avoiding bony areas. It is crucial to place the stethoscope over lung tissue rather than bony prominences to accurately assess lung sounds.

5. Patients exhibiting signs of cyanosis will:

• A. show signs of hyperoxia.
• B. have increased O2 saturation.
• C. have blood levels of CO2 higher than O2 levels.
• D. None of the above.

Correct answer: C

Rationale: Cyanosis is a bluish discoloration of the skin and mucous membranes resulting from low blood oxygen levels. When a patient exhibits cyanosis, it indicates that their blood is poorly oxygenated, leading to a higher concentration of CO2 compared to oxygen. Options A and B are incorrect as cyanosis is associated with low oxygen levels, not hyperoxia or increased O2 saturation. Therefore, the correct answer is that patients exhibiting cyanosis will have blood levels of CO2 higher than O2 levels.
