Safe and Effective Care Environment NCLEX RN Questions

1. The Rule of Nines is used to:

A. determine the amount of the body surface that has been burned
B. assess the level of oxygen saturation in a body that has been burned.
C. determine the level of tissue damage that has occurred in a burn.
D. None of the above.

Correct answer: A

Rationale: The Rule of Nines is used to assess the amount of body surface that has been burned. Most body areas are divided out based on 9%, with the exception of the genitalia, which is only 1%.

2. A patient who is displaying the defense mechanism of Compensation would:

A. Refuse to hear unwanted information.
B. Transfer feelings of negativity to someone else.
C. Overemphasize behaviors which accommodate for perceived weaknesses.
D. Place blame on others for personal actions or mistakes.

Correct answer: C

Rationale: The correct answer is 'Overemphasize behaviors which accommodate for perceived weaknesses.' Compensation involves overemphasizing or exaggerating a particular behavior or trait to make up for or cover up perceived weaknesses in oneself. This defense mechanism allows individuals to focus on their strengths rather than acknowledging their shortcomings. Choices A, B, and D are incorrect. Refusing to hear unwanted information relates more to denial, transferring feelings of negativity to someone else is projection, and placing blame on others is an example of the defense mechanism known as externalization.

3. Penny Thornton has had a stroke, or CVA, and is having difficulty eating on her own. Soon, she will be getting some assistive devices for eating meals. Which healthcare worker will be providing Penny with these assistive devices?

A. A physical therapist
B. A speech therapist
C. A social worker
D. An occupational therapist

Correct answer: D

Rationale: An occupational therapist is the healthcare professional responsible for assessing the needs of individuals, like Penny, regarding assistive devices that aid them in their daily activities. In this case, assistive devices for eating, such as weighted plates and specialized utensils, are crucial for helping Penny regain independence in feeding herself. Physical therapists focus more on mobility and movement, speech therapists on communication and swallowing disorders, and social workers on providing emotional and social support. Therefore, the correct choice is the occupational therapist as they specialize in activities of daily living and promoting independence.

4. The nurse is taking an initial blood pressure reading on a 72-year-old patient with documented hypertension. How should the nurse proceed?

A. Cuff should be placed on the patient's arm and inflated 30 mm Hg above the point at which the palpated pulse disappears.
B. Cuff should be inflated to 200 mm Hg in an attempt to obtain the most accurate systolic reading.
C. Cuff should be inflated 30 mm Hg above the patient's pulse rate.
D. After confirming the patient's previous blood pressure readings, the cuff should be inflated 30 mm Hg above the highest systolic reading recorded.

Correct answer: C

Rationale: When measuring blood pressure, it's important to account for the possibility of an auscultatory gap, which occurs in about 5% of individuals, particularly those with hypertension due to a noncompliant arterial system. To detect an auscultatory gap, the cuff should be inflated 20 to 30 mm Hg beyond the point at which the palpated pulse disappears. This ensures an accurate measurement of blood pressure by overcoming the potential gap in sounds. Choice A is correct as it follows this guideline. Choices B and C are incorrect because inflating the cuff to 200 mm Hg or above the patient's pulse rate does not address the specific issue of an auscultatory gap. Choice D is incorrect as it focuses on the patient's previous readings rather than the current measurement technique needed to detect an auscultatory gap.

5. Over a patient's lifespan, how does the pulse rate change?

A. starts out fast and decreases as the patient ages.
B. starts out slower and increases as the patient ages.
C. varies from slow to fast throughout the lifespan.
D. stays consistent from birth to death.

Correct answer: A

Rationale: The correct answer is that the pulse rate starts out fast and decreases as the patient ages. In infants, the normal pulse rate is around 140 beats per minute, which then falls to an average of 80 beats per minute in adults. As individuals age, their pulse rate tends to decrease due to changes in cardiovascular function. Choice B is incorrect as the pulse rate typically decreases with age, rather than increases. Choice C is incorrect as there is a general trend of decreasing pulse rate as individuals age, rather than a continuous variation. Choice D is incorrect as the pulse rate does change over a patient's lifespan, starting fast in infants and decreasing as they age.
