1. The healthcare professional notices that a colleague is preparing to check the blood pressure of a patient who is obese by using a standard-sized blood pressure cuff. How would this likely affect the blood pressure reading?

• A. Yield a falsely low blood pressure
• B. Yield a falsely high blood pressure
• C. Be the same, regardless of cuff size
• D. Vary as a result of the technique of the person performing the assessment

Correct answer: B

Rationale: Using a cuff that is too narrow for an obese patient would likely yield a falsely high blood pressure reading. This occurs because the standard cuff is too small for the arm's circumference, requiring more pressure to compress the artery. A tight cuff can lead to inaccurate and elevated blood pressure readings. Choices A, C, and D are incorrect because using an improperly sized cuff would not yield a falsely low blood pressure, the blood pressure reading does vary with cuff size, and the technique of the person performing the assessment is not the primary factor affecting the reading in this situation.

2. The healthcare provider is examining a patient who is reporting "feeling cold."? Which is a mechanism of heat loss in the body?

• A. Exercise
• B. Radiation
• C. Metabolism
• D. Food digestion

Correct answer: B

Rationale: When the body needs to lose heat, one of the mechanisms it employs is radiation. Radiation involves the transfer of heat from the body to the environment in the form of infrared waves. While metabolism, exercise, and food digestion contribute to heat production, they are not mechanisms for heat loss. Metabolism generates heat as a byproduct, exercise increases metabolic rate leading to heat production, and food digestion involves some heat generation, but these processes do not directly facilitate heat loss. Therefore, in the scenario where the patient is feeling cold, radiation is the primary mechanism for the body to lose excess heat and maintain a stable internal temperature.

3. Which of the following actions is most appropriate for reducing the risk of infection during the post-operative period?

• A. Flush the central line with heparin at least every four hours
• B. Administer narcotic analgesics as needed
• C. Remove the urinary catheter as soon as the client is ambulatory
• D. Order a high-protein diet for the client

Correct answer: C

Rationale: The most appropriate action to reduce the risk of infection during the post-operative period is to remove the urinary catheter as soon as the client is ambulatory. Urinary catheters can serve as a source of bacteria, increasing the risk of infection in the bladder or urethra. By removing the catheter promptly once the client is mobile, the risk of infection can be minimized. Option A, flushing the central line with heparin, is not directly related to reducing urinary tract infections. Option B, administering narcotic analgesics as needed, is important for pain management but does not directly address infection prevention. Option D, ordering a high-protein diet, may be beneficial for wound healing but does not specifically target infection risk reduction in the post-operative period.

4. 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.

5. A patient is bleeding profusely from an injury near her wrist. Which of the following first aid procedures would be MOST appropriate?

• A. Place a tourniquet on her arm above the injury.
• B. Place pressure on her brachial artery.
• C. Place pressure on her radial nerve.
• D. Cover the bleeding area with wet towels.

Correct answer: B

Rationale: The most appropriate first aid procedure for a patient bleeding profusely from an injury near the wrist is to place pressure on her brachial artery. Applying pressure to the brachial pulse point will help slow down the bleeding. Placing a tourniquet on her arm above the injury is not recommended as it could potentially inhibit blood flow, leading to tissue necrosis. Pressing on the radial nerve or covering the bleeding area with wet towels are not effective in controlling bleeding and may not address the underlying cause.
