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. Where is the duodenum located in the digestive system?

A. It is the first part of the small intestine, located immediately after the stomach.
B. It is the section of the digestive system where the gall bladder delivers bile.
C. It is the section of the small intestine where the pancreas delivers digestive juices.
D. None of the above.

Correct answer: D

Rationale: The duodenum is the first part of the small intestine, located immediately after the stomach. It is where the majority of digestion takes place in the gut. The pancreas delivers digestive juices containing amylase and lipase, while the gall bladder delivers bile to aid in the digestion of fats. Choice A incorrectly states that the duodenum is the third section of the small intestine, which is inaccurate. Choice B incorrectly associates the duodenum with the gall bladder, which is not where the duodenum is located. Choice C incorrectly states that the duodenum is where the pancreas delivers digestive juices, which is partly correct but not the main function of the duodenum. Therefore, the correct answer is 'None of the above' as none of the choices accurately describe the location or functions of the duodenum.

3. A healthcare professional is considering which patient to admit to the same room as a patient who had a liver transplant 3 weeks ago and is now hospitalized with acute rejection. Which patient would be the best choice?

A. Patient who is receiving chemotherapy for liver cancer
B. Patient who is receiving chemotherapy for lung cancer
C. Patient who has a wound infection after cholecystectomy
D. Patient who requires pain management for chronic pancreatitis

Correct answer: D

Rationale: The patient with chronic pancreatitis is the best choice to admit to the same room as a patient who had a liver transplant and is experiencing acute rejection. This is because the patient with chronic pancreatitis does not pose an infection risk to the immunosuppressed patient who had a liver transplant. On the other hand, patients receiving chemotherapy for cancer or those with wound infections are at risk for infections, which could endanger the immunosuppressed patient with acute rejection.

4. What is the primary route of transmission of MRSA?

A. Shared needles
B. Hands of healthcare workers
C. Items in the healthcare environment
D. Blood transfusions

Correct answer: B

Rationale: The correct answer is 'Hands of healthcare workers.' MRSA is primarily transmitted via the unwashed hands of healthcare workers who can carry the Staphylococcus aureus bacterium from one patient to another. Shared needles, items in the healthcare environment, and blood transfusions are not the main routes of transmission for MRSA. Shared needles can transmit bloodborne pathogens, items in the healthcare environment can harbor bacteria but are not the primary mode for MRSA, and blood transfusions are not a common route for MRSA transmission.

5. A client in a long-term care facility has developed reddened skin over the sacrum, which has cracked and started to blister. The nurse confirms that the client has not been assisted with turning while in bed. Which stage of pressure ulcer is this client exhibiting?

A. Stage I
B. Stage II
C. Stage III
D. Stage IV

Correct answer: B

Rationale: The client is exhibiting a stage II pressure ulcer. A stage II pressure ulcer develops as a partial thickness wound that affects both the epidermis and the dermal layers of skin. This stage can present with red skin, blisters, or cracking, appearing shallow and moist. However, the ulcer does not extend to the underlying tissues at this stage. Choice A (Stage I) is incorrect as Stage I ulcers involve non-blanchable redness of intact skin. Choices C (Stage III) and D (Stage IV) are incorrect as they involve more severe tissue damage, extending into deeper layers of the skin and underlying tissues, which is not the case in this scenario.
