Safe and Effective Care Environment NCLEX RN Questions
1. What is the initial step to take when a patient passes out at the front desk?
- A. Call 911.
- B. Initiate CPR.
- C. Shake the patient and ask if they are okay.
- D. Check for a pulse.
Correct answer: C
Rationale: The correct initial step when a patient passes out at the front desk is to shake the patient gently and ask if they are okay. This step aims to assess the patient's level of responsiveness. Checking for a pulse or initiating CPR should only be done if the patient does not respond to being shaken. Calling 911 can be the next step after assessing the patient's immediate condition and providing necessary assistance.
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. Surgical asepsis is being performed when:
- A. wiping down exam tables with bleach
- B. sterilizing instruments
- C. changing table paper
- D. wearing gloves when performing injections
Correct answer: B
Rationale: Surgical asepsis refers to the process of maintaining a sterile environment to prevent the introduction of pathogens to a patient's body. Sterilizing instruments is a crucial aspect of surgical asepsis as it ensures that the instruments used during procedures are free from microorganisms that could cause infections. Wiping down exam tables with bleach may help in cleaning and disinfecting surfaces but does not pertain directly to maintaining a sterile field. Changing table paper is important for cleanliness and infection control but is not specifically related to surgical asepsis. Wearing gloves when performing injections is important for standard precautions and preventing the spread of infection but does not encompass the concept of surgical asepsis, which focuses on maintaining a sterile field during invasive procedures.
4. 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.
5. Which gland of the endocrine system secretes a hormone that assists with the sleep/wake cycle?
- A. Pituitary
- B. Pineal
- C. Pancreas
- D. Hypothalamus
Correct answer: B
Rationale: The correct answer is the Pineal gland. The Pineal gland, located in the brain, secretes melatonin, which plays a crucial role in regulating the sleep/wake cycle in response to exposure to light. The Pituitary gland (Choice A) secretes various hormones but not specifically related to the sleep/wake cycle. The Pancreas (Choice C) secretes insulin and digestive enzymes, not hormones related to the sleep/wake cycle. The Hypothalamus (Choice D) is involved in regulating many bodily functions, including hormone secretion, but it does not directly secrete the hormone that regulates the sleep/wake cycle.
