Nursing Elites

1. When performing an EKG, the patient starts to laugh out of feelings of anxiety. What would you expect the EKG to show? (Choose the BEST answer.)

• A. Increased pulse rate, normal EKG
• B. Decreased pulse rate, abnormal EKG
• C. Tachycardia, poor EKG graph
• D. Bradycardia, poor EKG graph

Correct answer: C

Rationale: When a patient laughs due to anxiety during an EKG, it is likely to cause tachycardia, which is a rapid heart rate. This increased heart rate can lead to poor EKG graph quality as the electrical signals from large moving muscles can interfere with data collection from the chest leads. Therefore, in this scenario, the EKG is expected to show tachycardia with poor graph quality. Choices A, B, and D are incorrect because a patient laughing out of anxiety is more likely to result in an increased pulse rate (tachycardia) rather than a decreased pulse rate (bradycardia) or a normal EKG.

2. 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.

3. When considering the structural organization of the human body, what is the basic unit of life?

• A. Chemicals
• B. Atoms
• C. Molecules
• D. Cells

Correct answer: D

Rationale: The basic unit of life is the cell. Cells are considered the fundamental unit of life because they are capable of carrying out all the processes necessary for life, such as growth, reproduction, responding to stimuli, and more. While chemicals, atoms, and molecules are essential components of cells and living organisms, they are not considered the basic unit of life. Chemicals are general substances, atoms are the smallest units of matter, and molecules are combinations of atoms. Therefore, the correct answer is cells, as they are the building blocks of all living organisms.

4. The nurse is assessing the vital signs of a 20-year-old marathon runner and documents the following vital signs: temperature"?36�C; pulse"?48 beats per minute; respirations"?14 breaths per minute; blood pressure"?104/68 mm Hg. Which statement is true concerning these results?

• A. The patient is experiencing bradycardia.
• B. These are normal vital signs for a healthy, athletic adult.
• C. The patient's pulse rate is not normal"?no action is required.
• D. The patient's next clinic visit should occur as scheduled.

Correct answer: B

Rationale: The correct answer is, 'These are normal vital signs for a healthy, athletic adult.' A pulse rate of 48 beats per minute is considered bradycardia in adults, but it is not a concern in well-trained athletes like marathon runners. Bradycardia is a normal physiological response to aerobic conditioning. Tachycardia, on the other hand, is defined as a pulse rate above 100 beats per minute, which is not the case here. The low pulse rate in this scenario is a reflection of the athlete's cardiovascular fitness. Therefore, there is no need to notify the physician or schedule a follow-up visit based on these findings.

5. For a healthcare worker under normal conditions with unsoiled hands, effective hand hygiene between patients requires which of the following?

• A. At least a 15-second scrub with plain soap and water
• B. At least a 23-minute scrub with an antimicrobial soap
• C. Use of an alcohol-based antiseptic hand-rub
• D. Wearing a mask when scrubbing

Correct answer: C

Rationale: Effective hand hygiene between patients for a healthcare worker with unsoiled hands involves using an alcohol-based antiseptic hand rub. This method is sufficient for cleaning hands that are not visibly soiled. The use of an antimicrobial soap or a prolonged scrubbing time is unnecessary and not recommended in this scenario. Wearing a mask is not required for routine hand hygiene and does not contribute to effective hand cleaning.
