Nursing Elites

1. 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.

2. The healthcare professional has collected the following information on a patient: palpated blood pressure"?180 mm Hg; auscultated blood pressure"?170/100 mm Hg; apical pulse"?60 beats per minute; radial pulse"?70 beats per minute. What is the patient's pulse pressure?

• A. 10
• B. 70
• C. 80
• D. 100

Correct answer: B

Rationale: Pulse pressure is the numerical difference between the systolic and diastolic blood pressure readings. In this case, the systolic blood pressure is 170 mm Hg, and the diastolic blood pressure is 100 mm Hg. Therefore, the pulse pressure is calculated as 170 - 100 = 70 mm Hg. Pulse pressure reflects the stroke volume, the amount of blood ejected from the heart with each beat. Choices A, C, and D are incorrect because they do not accurately represent the difference between the systolic and diastolic blood pressure readings provided.

3. Which of the following is one of the three smallest bones in the body?

• A. Vomer
• B. Distal phalanx of the small toe
• C. Stapes
• D. Coccyx

Correct answer: C

Rationale: The stapes, along with the malleus and incus, are the three smallest bones in the human body. These bones are located in the inner ear and play a crucial role in hearing. The vomer is a bone in the nasal cavity and is not one of the smallest bones. The distal phalanx of the small toe is relatively larger and not among the smallest bones. The coccyx, also known as the tailbone, is not one of the smallest bones in the body.

4. The nurse receives change-of-shift report on the following four patients. Which patient should the nurse assess first?

• A. A 23-year-old patient with cystic fibrosis who has pulmonary function testing scheduled
• B. A 46-year-old patient on bed rest who is complaining of sudden onset of shortness of breath
• C. A 77-year-old patient with tuberculosis (TB) who has four antitubercular medications due in 15 minutes
• D. A 35-year-old patient who was admitted the previous day with pneumonia and has a temperature of 100.2 F (37.8 C)

Correct answer: B

Rationale: The correct answer is the 46-year-old patient on bed rest who is complaining of sudden onset of shortness of breath. Patients on bed rest who are immobile are at high risk for deep vein thrombosis (DVT). Sudden onset of shortness of breath in a patient with a DVT suggests a pulmonary embolism, which requires immediate assessment and action such as oxygen administration to maintain adequate oxygenation. The other patients should also be assessed as soon as possible, but they do not present with an immediate life-threatening condition that requires urgent intervention like the patient experiencing sudden shortness of breath.

5. According to the American Heart Association standards, high-quality CPR for an adult includes all of the following EXCEPT:

• A. Push hard
• B. Push fast
• C. Allow chest recoil between compressions
• D. Pause CPR as each drug is administered

Correct answer: D

Rationale: High-quality CPR for adults should not be paused for drug administration. The correct CPR technique involves pushing hard and fast, at a rate of at least 100 compressions per minute and to a depth of at least 2 inches. It is also essential to allow chest recoil between compressions to enable proper blood circulation. Pausing CPR for drug administration would delay the delivery of continuous chest compressions, which are crucial for maintaining blood flow and oxygenation during cardiac arrest.
