Nursing Elites

1. A patient's blood pressure is 118/82 mm Hg. The patient asks the nurse, "What do the numbers mean?"? Which is the best reply by the nurse?

• A. "The numbers are within the normal range and are nothing to worry about."?
• B. "The bottom number is the diastolic pressure and reflects the pressure in the arteries when the heart relaxes."?
• C. "The top number is the systolic blood pressure and reflects the pressure of the blood against the arteries when the heart contracts."?
• D. "The concept of blood pressure can be complex. The primary thing to be concerned about is the top number, or the systolic blood pressure."?

Correct answer: C

Rationale: The systolic pressure is the maximum pressure felt on the artery during left ventricular contraction, or systole. The diastolic pressure is the elastic recoil, or resting, pressure that the blood constantly exerts in between each contraction. The nurse should answer the patient's question in terms they can understand and not just say it is normal and there is nothing to worry about. The diastolic pressure is the pressure in the vessels when the heart is at rest, not the stroke volume. Both the systolic and diastolic blood pressure are important. Choice A is incorrect as providing a vague reassurance does not address the patient's query. Choice B is incorrect as it inaccurately describes the diastolic pressure as reflecting stroke volume, which is incorrect. Choice D is incorrect as it oversimplifies the explanation, focusing solely on the top number without providing a complete understanding of blood pressure.

2. Patients exhibiting signs of cyanosis will:

• A. show signs of hyperoxia.
• B. have increased O2 saturation.
• C. have blood levels of CO2 higher than O2 levels.
• D. None of the above.

Correct answer: C

Rationale: Cyanosis is a bluish discoloration of the skin and mucous membranes resulting from low blood oxygen levels. When a patient exhibits cyanosis, it indicates that their blood is poorly oxygenated, leading to a higher concentration of CO2 compared to oxygen. Options A and B are incorrect as cyanosis is associated with low oxygen levels, not hyperoxia or increased O2 saturation. Therefore, the correct answer is that patients exhibiting cyanosis will have blood levels of CO2 higher than O2 levels.

3. An 86-year-old client with decreased visual acuity who uses a cane for mobility requires fall prevention education. What should the nurse teach this client to reduce the risk of falling at home?

• A. Take off shoes while in the house and wear only socks
• B. Limit activities to the lower level of the home
• C. Keep a lamp near the door of every room
• D. Install non-slip pads in the shower or bathtub

Correct answer: D

Rationale: To reduce the risk of falling at home for an elderly client with decreased visual acuity and using a cane for mobility, installing non-slip pads in the shower or bathtub is crucial. This measure helps prevent slips and falls in areas where water accumulation may occur. While taking off shoes and wearing socks may seem comfortable, it increases the risk of slipping. Limiting activities to the lower level of the home may restrict the client's independence and quality of life unnecessarily. Keeping a lamp near the door of every room may improve visibility but does not directly address the risk of falls associated with mobility and visual acuity issues.

4. What is a common error when taking a pulse?

• A. Placing the index finger on the radial artery located on the thumb side of a patient's wrist.
• B. Noting a pulse as 'weak' when the pulsation disappears upon adding pressure.
• C. Counting the pulse for 15 seconds and multiplying the number by four.
• D. None of the above will cause errors.

Correct answer: C

Rationale: The correct answer is counting the pulse for 15 seconds and multiplying the number by four. To accurately assess a patient's heart rate or pulse, it is crucial to count the pulse for a full minute. Counting for only 15 seconds and then multiplying by four may result in an inaccurate heart rate calculation. This approach could miss arrhythmias or intermittent pulsations that could be vital indicators of the patient's condition. Placing the index finger on the radial artery, which is located on the thumb side of the patient's wrist, is the correct technique for taking a pulse. Noting a pulse as 'weak' when the pulsation disappears upon adding pressure is a valid observation and not an error in itself. Therefore, the most common error in this scenario is incorrectly calculating the pulse rate by multiplying a 15-second count by four.

5. While explaining an illness to a 10-year-old, what should the nurse keep in mind about the cognitive development at this age?

• A. They are able to make simple associations of ideas
• B. They are able to think logically in organizing facts
• C. Interpretation of events originates from their own perspective
• D. Conclusions are based on previous experiences

Correct answer: B

Rationale: At the age of 10, children are in the concrete operations stage according to Piaget. They are capable of mature thought when allowed to manipulate and organize objects. This means they can think logically, organize facts, and understand cause-and-effect relationships. Choices A, C, and D are incorrect. While simple associations of ideas may occur, the key cognitive ability at this stage is the capacity for logical thought and organization of information. Interpretation of events from their own perspective is more characteristic of younger children, and conclusions based on previous experiences are more aligned with older children or adults.
