Nursing Elites

1. You see a sign over Mary Jones' bed when you arrive at 7 am to begin your day shift. The sign says, 'NPO'. Ms. Jones is on a regular diet. The patient asks for milk and some crackers. You _____________.

• A. can give her the milk but not the crackers
• B. can give her both the milk and the crackers
• C. can give her the crackers but not the milk
• D. cannot give her anything to eat or drink

Correct answer: D

Rationale: The correct answer is that you cannot give her anything to eat or drink. 'NPO' is the standard abbreviation for 'nothing by mouth,' indicating that the patient should not consume any food or liquids. It is crucial to adhere to this restriction to prevent any potential harm or complications in the patient's condition. Choices A, B, and C are incorrect because 'NPO' clearly specifies that the patient should not have anything to eat or drink, including milk and crackers. Providing these items could lead to adverse effects, so it is essential to follow the 'NPO' directive strictly.

2. How many cc are there in 25 ounces?

• A. 250
• B. 500
• C. 750
• D. 1000

Correct answer: C

Rationale: To convert ounces to cc, we know that there are 30 cc in 1 ounce. Therefore, to find out how many cc are in 25 ounces, we multiply 30 cc/ounce by 25 ounces which equals 750 cc. This makes choice C, 750, the correct answer. Choices A, B, and D are incorrect as they do not correctly convert ounces to cc.

3. When providing endotracheal suctioning, for how long should the nurse suction the endotracheal tube of an intubated client on a ventilator at a time?

• A. Five seconds or less
• B. Ten seconds or less
• C. At least 30 seconds
• D. No longer than 60 seconds

Correct answer: B

Rationale: When providing endotracheal suctioning, the nurse should suction for no longer than ten seconds at a time. Suctioning for longer than ten seconds may cause hypoxia or bronchospasm. Extended suctioning may also place the client at risk of injury to the bronchial and tracheal structures. Choices C and D suggest prolonged suctioning durations that can lead to adverse effects on the client. Choice A, suctioning for five seconds or less, may not be adequate to clear secretions effectively, making choice B the most appropriate duration for safe and efficient suctioning in this scenario.

4. 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.

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.
