1. When considering the concepts related to blood pressure, which statement best describes the concept of mean arterial pressure (MAP)?

• A. MAP is the pressure of the arterial pulse.
• B. MAP reflects the stroke volume of the heart.
• C. MAP is the pressure forcing blood into the tissues, averaged over the cardiac cycle.
• D. MAP is an average of the systolic and diastolic blood pressures and reflects tissue perfusion.

Correct answer: C

Rationale: Mean Arterial Pressure (MAP) is the pressure that forces blood into the tissues, averaged over the cardiac cycle. It is not the pressure of the arterial pulse (Choice A), nor does it directly reflect the stroke volume of the heart (Choice B). While MAP involves systolic and diastolic pressures, it is not simply an average of these two values as diastole lasts longer. Instead, MAP is closer to diastolic pressure plus one third of the pulse pressure. The best description of MAP is that it represents the pressure forcing blood into the tissues, averaged over the cardiac cycle.

2. Which of the following constitutes the five rights of medication administration?

• A. Right client, right nurse, right time, right dose, right route
• B. Right client, right time, right dose, right route, right order
• C. Right client, right drug, right dose, right time, right route
• D. Right physician, right nurse, right client, right drug, right dose

Correct answer: C

Rationale: The five rights of medication administration are essential to ensure safe and effective drug delivery to clients. The correct answer includes ensuring the right client receives the right drug at the right dose, via the right route, and at the right time. These elements are crucial to prevent medication errors and ensure optimal therapeutic outcomes. Choice A is incorrect as it includes 'right nurse' which is not part of the five rights of medication administration. Choice B is incorrect as it includes 'right order' which is not part of the five rights. Choice C is incorrect as it includes 'right drug' and 'right route', but it lacks 'right client' and 'right time'. Choice D is incorrect as it includes 'right physician' which is not part of the five rights.

3. A client is taking a walk down the hallway when she suddenly realizes that she needs to use the restroom. Although she tries to make it to the bathroom on time, she is incontinent of urine before reaching the toilet. What type of incontinence does this situation represent?

• A. Relex incontinence
• B. Urge incontinence
• C. Total incontinence
• D. Functional incontinence

Correct answer: D

Rationale: Functional incontinence occurs when a client develops an urge to void but may not be able to reach the toilet in time. In this scenario, the client had the urge to use the restroom but was unable to make it in time, leading to incontinence. Functional incontinence may be related to conditions that cause the client to forget bladder sensation until the last minute, such as cognitive changes, or the client may have mobility problems that prevent her from reaching the bathroom in time. Choice A, Reflex incontinence, is incorrect as reflex incontinence is characterized by the involuntary loss of urine due to hyperreflexia of the detrusor muscle. Choice B, Urge incontinence, is not the correct answer as urge incontinence is the involuntary loss of urine associated with a strong desire to void. Choice C, Total incontinence, is also incorrect as it refers to the continuous and unpredictable loss of urine, not specifically related to the inability to reach the toilet in time.

4. 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.

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.
