Safe and Effective Care Environment NCLEX RN Questions

1. 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.

2. What does preload refer to?

A. The volume of blood entering the left side of the heart
B. The volume of blood entering the right side of the heart
C. The pressure in the venous system that the heart must overcome to pump the blood
D. The pressure in the arterial system that the heart must overcome to pump the blood

Correct answer: B

Rationale: Preload refers to the volume of blood that enters the right side of the heart. This volume stretches the fibers in the heart before contraction. Preload is an essential factor in determining the force of ventricular contraction. Choices A, C, and D are incorrect. Choice A is incorrect because preload is specifically related to the volume of blood entering the right side of the heart. Choices C and D are incorrect as they refer to afterload, which is the pressure that the heart must overcome to pump blood out of the ventricles into the systemic or pulmonary circulation.

3. The nurse is preparing to perform a physical assessment. The correct action by the nurse is reflected by which statement?

A. Performs the examination from both sides of the bed.
B. Examines tender or painful areas last to help relieve the patient's anxiety.
C. Follows a flexible examination sequence, considering the patient's age and condition.
D. Organizes the assessment to ensure that the patient does not change positions too often.

Correct answer: D

Rationale: The nurse should organize the assessment to minimize the patient's need to change positions frequently, ensuring efficiency and comfort. It is essential to perform the examination from both sides of the bed to facilitate a comprehensive assessment. Examining tender or painful areas last can help reduce patient discomfort and anxiety. The examination sequence should be flexible, taking into account the patient's age, condition, and specific needs. This approach allows for a tailored and patient-centered assessment, optimizing the quality of care provided.

4. Nursing care plans are _______________?

A. written by CNAs before they provide care
B. guidelines of care that all nursing team members use
C. used by nurses but not by nursing assistants
D. used by nursing assistants but not by nurses

Correct answer: B

Rationale: Nursing care plans are comprehensive documents created by registered nurses to outline individualized care for patients. These plans serve as guidelines for all members of the nursing team, including nursing assistants, to ensure consistent and quality care. Choice A is incorrect as CNAs typically assist in implementing the care plan rather than creating it. Choice C is incorrect as nursing care plans are utilized by all members of the nursing team, not exclusive to only nurses. Choice D is incorrect as nursing assistants also utilize nursing care plans to provide patient care effectively.

5. A client is complaining of pain in his right hand after surgery. The IV in his hand has slowed down, and the skin around the site is reddened and cool. The client reports localized pain in the hand and fingers. What is the most likely cause of this client's pain?

A. The client's IV is infiltrated
B. The client is experiencing phlebitis from the last drug administered
C. The client has a blood clot developing in the distal arteries of the wrist
D. The client's pain is associated with myocardial ischemia and he is having a heart attack

Correct answer: A

Rationale: Pain, cool skin, and edema at an IV injection site indicate IV infiltration. The reddened and cool skin around the IV site, along with localized pain and a slowed IV drip rate, are classic signs of infiltration. Infiltration occurs when IV fluids or medications enter the surrounding tissues instead of the vein, leading to potential tissue damage. Phlebitis is inflammation of a vein, not infiltration. A blood clot in the distal arteries of the wrist would not cause these specific symptoms. Myocardial ischemia and heart attack are unrelated to the client's localized hand pain and IV issues.
